<abstract>
<p>Residents&#x2019; environmental perception affects lifestyle choices, which in turn shape health status. Using 2,006 valid samples from the Chinese General Social Survey (CGSS2021), this study employed the multinomial Logit model and mediating effect model to explore the mechanism among environmental perception, lifestyle, and health. Key findings: (1) Residents are optimistic about macro environmental risks (e.g., air/water pollution) but sensitive to specific risks (e.g., vehicle exhaust); (2) Environmental perceptions (e.g., extreme weather, food safety concerns) positively impact health, while air pollution perception shows no direct promoting effect; (3) Unhealthy lifestyles (insufficient physical activity, irregular sleep) harm health, while adequate sleep and leisure/relaxation (especially frequent relaxation) benefit health; (4) Lifestyle plays a key mediating role: positive environmental perception improves health by enhancing social fairness and promoting social activities, while heightened environmental risk perception inhibits regular exercise, triggering &#x201C;environmental pressure-behavioral disorder-health deterioration.&#x201D; Innovatively, the study clarifies the chained mechanism of &#x201C;environmental perception-lifestyle-health&#x201D; via combined models. Practically, it proposes a health promotion system integrating environmental governance optimization and behavioral intervention, to facilitate a &#x201C;cognition-behavior-health&#x201D; virtuous cycle.</p>

<title>Introduction</title>
<p>As global health awareness continues to grow, it&#x2019;s clear that individual health is shaped by multiple interconnected factors. The theory of social determinants of health reveals that health disparities aren&#x2019;t just about biological differences&#x2014;they are largely driven by complex social mechanisms (<xref ref-type="bibr" rid="ref1">1</xref>). Non-medical factors like living environment, economic status, and social support play a decisive role in determining health outcomes (<xref ref-type="bibr" rid="ref2">2</xref>, <xref ref-type="bibr" rid="ref3">3</xref>). For instance, people living in areas with severe air pollution and poor sanitation infrastructure suffer from higher rates of respiratory diseases compared to those in ecologically balanced neighborhoods (<xref ref-type="bibr" rid="ref4">4</xref>). Moreover, individuals with lower socioeconomic status face a dual challenge: they struggle to access quality healthcare and nutritious food, while chronic stress makes them more vulnerable to mental health issues. These interconnected social factors collectively create distinct health disparity patterns across different social groups. A telling example comes from Hu&#x2019;s et al. (<xref ref-type="bibr" rid="ref5">5</xref>) study using China Health and Retirement Longitudinal Study data (2011&#x2013;2018) and PM2.5 satellite monitoring, which revealed significant urban&#x2013;rural differences in how air pollution affects middle-aged and older adult. Therefore, understanding the relationship between environment and individual health requires careful examination of how various social factors work together as a whole.</p>
<p>It is evident that the living environment directly shapes residents&#x2019; environmental perceptions, which in turn influence physical health through an interconnected &#x201C;physiological-psychological-behavioral&#x201D; process. The direct pathway demonstrates the mind&#x2019;s immediate control over bodily responses (<xref ref-type="bibr" rid="ref6">6</xref>, <xref ref-type="bibr" rid="ref7">7</xref>), while the indirect pathway reveals how behavioral patterns serve as key bridges linking environmental impact to health outcomes (<xref ref-type="bibr" rid="ref8">8</xref>, <xref ref-type="bibr" rid="ref9">9</xref>). This establishes &#x201C;environmental perception and physical health&#x201D; as a critical research theme. For instance, Russ (<xref ref-type="bibr" rid="ref10">10</xref>) investigated the potential effects of environmental perception on human health, while Adanu et al. (<xref ref-type="bibr" rid="ref11">11</xref>) demonstrated significant correlations between perceived environmental hazards and health risks. Notably, negative environmental perceptions may lead residents to reduce outdoor social activities and increasingly adopt sedentary indoor entertainment (e.g., prolonged television viewing), thereby exacerbating loneliness and physical inactivity&#x2014;ultimately compromising health. This dynamic aligns with Bronfenbrenner&#x2019;s socio-ecological model (<xref ref-type="bibr" rid="ref12">12</xref>), which posits that health behaviors emerge from continuous interactions between individuals and multi-layered environmental systems, including living spaces and community contexts. Thus, environmental perceptions&#x2014;rooted in societal evolution&#x2014;directly and indirectly shape physical health, creating a fluid interplay that warrants continued scholarly exploration.</p>
<p>It is note that Rogers&#x2019; Protection Motivation Theory (1975) further posits that environmental perception directly influences an individual&#x2019;s willingness to adopt protective behaviors. Higher risk perception strengthens motivation to act, whereas lower awareness weakens protective motivation (<xref ref-type="bibr" rid="ref13">13</xref>). Consequently, choosing healthy lifestyles&#x2014;such as maintaining regular physical activity, consistent sleep patterns, adequate relaxation, balanced fruit intake, and social engagement&#x2014;can foster positive interactions between individuals and their environment. These constructive lifestyle practices enhance residents&#x2019; adaptability to their surroundings and reduce environment-related health risks (<xref ref-type="bibr" rid="ref14">14</xref>). For instance, Makeen et al. (<xref ref-type="bibr" rid="ref15">15</xref>) conducted in-depth analyses of the complex interrelationships among different lifestyle factors, revealing diverse risk perception patterns and varying health outcomes associated with different behavioral choices (<xref ref-type="bibr" rid="ref16">16</xref>). This demonstrates that lifestyle serves as an essential pathway through which environmental perception affects physical health. Therefore, when examining the relationship between environmental perception and health outcomes, lifestyle must be considered an indispensable mediating variable. Regarding research approaches and perspectives, existing studies often examine environmental perception or lifestyle in isolation when exploring their connections to physical health (<xref ref-type="bibr" rid="ref17 ref18 ref19">17&#x2013;19</xref>). However, quantitative investigation into the underlying mechanism of how environmental perception influences health through lifestyle remains insufficient&#x2014;representing a key research motivation for this study.</p>
<p>The impact of lifestyle on health and its quantitative assessment require further research. As a multidimensional variable encompassing perceptions of the physical, social, and psychological environments, environmental perception systematically influences residents&#x2019; lifestyle choices through their subjective interpretation of environmental factors, ultimately manifesting in health outcomes. We know that individual healthy lifestyle choices are affected by numerous factors, such as education level, health awareness, dietary habits, and economic income. Relevant studies indicate that individuals with higher health awareness are more inclined to consciously cultivate healthy lifestyles; similarly, those with higher education levels tend to adopt more scientifically sound health behaviors due to their deeper understanding of health knowledge (<xref ref-type="bibr" rid="ref20">20</xref>, <xref ref-type="bibr" rid="ref21">21</xref>). Although existing research has extensively explored the impact of lifestyle on physical health, most studies remain theoretical or focus primarily on statistical analysis (<xref ref-type="bibr" rid="ref22">22</xref>). There is a lack of theoretical interpretation supported by multi-case comparisons or empirical testing, and the robustness of their conclusions still needs verification. Establishing a &#x201C;environmental perception&#x2014;lifestyle&#x2014;physical health&#x201D; causal chain with lifestyle as the mediating variable, and analyzing how environmental perception drives lifestyle choices (<xref ref-type="bibr" rid="ref23">23</xref>) to reveal the internal mechanism between environment and health&#x2014;this constitutes the second research motivation of this paper.</p>
<p>This study focuses on the domain of physical health, employing lifestyle as a mediating variable to examine its dynamic mechanism within the relationship between environmental perception and physical health. Guided by the &#x201C;environmental perception&#x202F;&#x2192;&#x202F;lifestyle choices&#x202F;&#x2192;&#x202F;health status&#x201D; analytical framework, we utilize baseline regression and multinomial Logit models for quantitative analysis, aiming to unveil the underlying pathways and transmission effects among these variables. Based on this foundation, we propose the following research hypotheses to advance subsequent investigation.</p>
<disp-quote>
<p><italic>H1</italic>: Environmental perceptions exert a significant and differentiated impact on lifestyles. Specifically, the perception of environmental factors related to food and residential safety demonstrates a positive predictive effect on the adoption of healthy lifestyle behaviors.</p>
</disp-quote>
<disp-quote>
<p><italic>H2</italic>: On weekdays, opting for adequate sleep and relaxation is the preferred choice for residents to maintain their health.</p>
</disp-quote>
<disp-quote>
<p><italic>H3</italic>: Environmental perception exerts differential effects on residents&#x2019; physical health, depending on its specific level.</p>
</disp-quote>
<disp-quote>
<p><italic>H4</italic>: Lifestyle plays a mediating role in the relationship between environmental perception and physical health, whereby individuals&#x2019; lifestyle choices lead to varied health outcomes.</p>

<title>Data source, reconstruction and specification</title>
<p>The data used in this study is sourced from the database of the Chinese General Social Survey (CGSS2021) in 2021.<xref ref-type="fn" rid="fn0001"><sup>1</sup></xref> This survey adopted a multi-stage stratified sampling method, taking a total of 2,801 district and county units in 22 provinces, 4 autonomous regions (excluding the Tibet Autonomous Region), and 4 directly-administered municipalities (excluding Hong Kong, Macau and Taiwan) in China as the primary sampling units (PSUs). In this paper, the core independent variables of these models are environmental perception level,<xref ref-type="fn" rid="fn0002"><sup>2</sup></xref> the mediating variable is lifestyle,<xref ref-type="fn" rid="fn0003"><sup>3</sup></xref> and the explained variables are physical health status.<xref ref-type="fn" rid="fn0004"><sup>4</sup></xref></p>
<p>After data cleaning, by removing the missing values and invalid records in the research indicators, a total of 2,006 valid samples were finally obtained. Among them, males accounted for 45.8% and females accounted for 54.2%. To ensure the consistency of variable measurement standards during the model construction process, all variables were quantitatively coded using a five-point scale, to achieve the standardization of data dimensions. The specific operations of data reconstruction and standardized assignment are as follows (Other variables adopt the original 5-point Likert scale data structure):</p><list list-type="order">

<p>The &#x201C;current physical health status&#x201D; (Health) was set as the dependent variable of the study, and its values were reassigned as: 1&#x202F;=&#x202F;poor, 2&#x202F;=&#x202F;average, 3&#x202F;=&#x202F;good, 4&#x202F;=&#x202F;very good, 5&#x202F;=&#x202F;excellent, so as to establish a unified quantitative standard for the subsequent analysis of the influencing factors of health.</p>
<p>The core variable explanations and some specifications are presented in <xref ref-type="table" rid="tab1">Table 1</xref>. In particular, the present research focuses on investigating the impact of environmental perception levels and lifestyle choices on residents&#x2019; physical health. Accordingly, the independent variables of the proposed model are primarily anchored in environmental perception variables, which serve as the core explanatory variables. Nevertheless, residents&#x2019; social attribute characteristics constitute non-negligible factors. To validate the robustness of the established model, the three characteristic variables&#x2014;i.e., &#x201C;Gender,&#x201D; &#x201C;Education Level,&#x201D; and &#x201C;Economic Income&#x201D;&#x2014;were incorporated into the correspondingly constructed model in the experimental results and analysis section. Subsequent to recalculating the model parameters, a comparative analysis was conducted against the previously derived results. This analytical procedure aims to elucidate the influence of residents&#x2019; social attributes (among the independent variables) on both the mediating variable (lifestyle) and the explained variable (physical health status).</p>

<title>Research framework</title>
<p>We first provide a statistical description of all selected sample data in Section 4.1, which serves as an initial data exploration. In Section 4.2, we analyze the impact effect of environmental perception (independent variable) on lifestyle (mediating variable) based on Model <xref ref-type="disp-formula" rid="E1">1</xref>. In Section 4.3, focusing on &#x201C;lifestyle&#x201D; and based on Models <xref ref-type="disp-formula" rid="E3">2</xref>, <xref ref-type="disp-formula" rid="E4">3</xref>, we use multinomial Logit models to analyze the issue of residents&#x2019; lifestyle selection probability from both overall data and partial sampling data. In Section 4.4, we divide the analysis into two parts based on Models <xref ref-type="disp-formula" rid="E5">4</xref>, <xref ref-type="disp-formula" rid="E6">5</xref>: the first part examines the impact effect of environmental perception on physical health status (dependent variable); the second part analyzes the impact effects of environmental perception and lifestyle on physical health status after incorporating the mediating variable (lifestyle). In Section 4.5, the analysis mainly focuses on the direct mediating effect and transmission mechanism of the lifestyle on the physical health status. In Section 4.6, to verify the robustness and validity of the results obtained from Models <xref ref-type="disp-formula" rid="E1">1</xref>, <xref ref-type="disp-formula" rid="E5">4</xref>, and <xref ref-type="disp-formula" rid="E6">5</xref>, we incorporate social attribute variables&#x2014;namely &#x201C;gender,&#x201D; &#x201C;education level,&#x201D; and &#x201C;economic income&#x201D;&#x2014;into the independent variables of the models respectively, then conduct regression calculations again to test the validity of Models <xref ref-type="disp-formula" rid="E1">1</xref>, <xref ref-type="disp-formula" rid="E5">4</xref>, <xref ref-type="disp-formula" rid="E6">5</xref>.

<title>Research models</title>
<p>In this section, we regress the environmental perception variables on the lifestyle variables, while the coefficients of this regression model are used to calculate the multinomial Logit model. The aim is to obtain the probability of residents&#x2019; lifestyle choices under the influence of environmental perception. We then conduct a regression analysis of the environmental perception variables on residents&#x2019; physical health variables, and subsequently incorporate the lifestyle to derive a mediating regression model. This enables a closed-loop analysis that captures the effects of &#x201C;environmental perception&#x201D; on &#x201C;lifestyle&#x201D; and &#x201C;lifestyle&#x201D; on &#x201C;physical health.&#x201D;</p>

<p>This study focuses on the impact of residents&#x2019; lifestyle choices. The multinomial Logit model (<xref ref-type="bibr" rid="ref24">24</xref>, <xref ref-type="bibr" rid="ref25">25</xref>) is applied to quantitatively analyze the probability of residents&#x2019; choices among different lifestyle options. This study uses a precise statistical model to examine how people&#x2019;s perception of their environment shapes their lifestyle choices and, ultimately, their health. The model calculates the probability of an individual making a specific choice using the following formula:</p><disp-formula id="E2">

<title>Descriptive statistics analysis</title>
<p>Based on the availability of data,<xref ref-type="fn" rid="fn0005"><sup>5</sup></xref> this study selected 10 environmental perception variables (AirP, WaterP, ExtWea, VehExh, PesFer, GenCr, FoSaf, LivEnv, VegFru, PubFac) and seven lifestyle variables (Lifestyle<sub>1</sub>&#x2013;Lifestyle<sub>7</sub>) with 2006 samples. The specific interpretations are shown in <xref ref-type="table" rid="tab1">Table 1</xref>. The results of the reliability test show that Cronbach&#x2019;s coefficient of the environmental perception variables is 0.778, and Cronbach&#x2019;s coefficient of the lifestyle variables is 0.721, indicating that the selected scales have a high level of internal consistency reliability.</p>
<p>The results of the descriptive statistics show (as shown in <xref ref-type="table" rid="tab1">Table 1</xref>): In the dimension of environmental perception, the mode of residents&#x2019; perception levels of air pollution, water pollution and extreme weather is all 1, and the mean value is approximately 2, indicating that most residents hold an optimistic attitude towards the environmental safety of their place of residence. The mode of the perception of the hazards of vehicle exhaust is 3, showing that the public has certain concerns about this type of pollution; the situations of the perception of the hazards of the use of pesticides and fertilizers and genetically modified crops are similar, indicating that residents are relatively sensitive to environmental risks related to agricultural production. In addition, both the mode and the mean value of the perception of living resources such as places for physical exercise, the supply of fruits and vegetables, and the public facilities that can be enjoyed are close to 4, indicating that residents pay high attention to basic living security.</p>
<p>In the dimension of lifestyle, the survey data on physical activities, physical exercises and work regularity show that residents generally have less physical exercise, and there are irregularities in their work and rest schedules. The mode of the perception of social fairness is 4, with a mean value of approximately 3.38, indicating that most residents have a positive evaluation of social fairness. The statistical results of sleep duration, relaxation and rest, and social and entertainment activities also concentrate around 4, indicating that residents&#x2019; states in these aspects of life tend to be normal.</p>
<p>Among the 10 environmental perception variables, the sample data exhibit the largest standard deviation in residents&#x2019; perception of food safety, with a value of 1.7932. This result indicates that significant disparities exist in people&#x2019;s perception of food safety across different regions. Regarding the mediating variables, the data distribution of the lifestyle dimension&#x2014;&#x201C;residents engaging in physical activities that induce sweating for a minimum of 20&#x202F;min&#x201D;&#x2014;exhibits relatively high dispersion, as evidenced by the largest standard deviation of 1.5909. Regarding the data of the explained variable &#x201C;physical health status,&#x201D; its mode is 5, mean is 4.0583, and standard deviation is 0.6378. This result indicates that the vast majority of respondents have an excellent physical health status.</p>

<title>The influence results of environmental perception on lifestyles based on Model 1</title>
<p>Based on the maximum likelihood estimation method, we carried out parameter estimation for Model <xref ref-type="disp-formula" rid="E1">1</xref>, and the results are shown in <xref ref-type="table" rid="tab2">Table 2</xref>. Taking the dependent variable Lifestyle<sub>1</sub> (representing &#x201C;the duration of physical activities with a faster breathing rate than the general situation per week&#x201D;) in the mediating variable model as the research object, it was set as the reference group of the multinomial Logit model (assigned a value of 0). The study found that: for example, when <italic>j</italic>&#x202F;=&#x202F;1, the positive influencing factors include air pollution perception (AirP), extreme weather perception (ExtWea), awareness of the harm of genetically modified crops (GenCr), the environment for physical exercise (LivEnv), and the supply of vegetables and fruits (VegFru), which means that the improvement of these environmental perception variables will encourage individuals to increase the time of physical activities; while variables such as water pollution perception (WaterP), vehicle exhaust perception (VehExh), awareness of the harm of pesticides and fertilizers (PesFer), food safety concerns (FoSaf), and the sense of identity with public facilities (PubFac) have a negative correlation with Lifestyle<sub>1</sub>. That is, when the perception levels of the above factors increase, the duration of high-intensity physical activities participated by individuals may be shortened.</p>

This indicates that these factors can positively promote regular physical exercise behavior. While the parameters of four variables, namely water pollution perception, vehicle exhaust perception, food safety concerns, and the supply of vegetables and fruits, are significantly negative, suggesting that they have an inhibitory effect on the willingness to engage in physical exercise.</p>
<p>When <italic>j</italic>&#x202F;=&#x202F;3, the &#x201C;the regularity of work schedule arrangements in daily life&#x201D; is taken as the dependent variable Lifestyle<sub>3</sub>, at the 5% significance level, 70% of the 10 environmental perception variables show a negative impact. Only the parameters of three variables, namely extreme weather perception, awareness of the harm of pesticides and fertilizers, and the environment for physical exercise, are significantly positive, meaning that most environmental factors may interfere with the regularity of work schedules.</p>
<p>When <italic>j</italic>&#x202F;=&#x202F;6, the dependent variable Lifestyle<sub>6</sub> is &#x201C;whether you often take a rest and relax in your free time,&#x201D; under the constraint of the 5% significance level, only the model parameters of water pollution perception and the perception of the suitability for physical exercise within 1&#x202F;km of the place of residence are significantly negative, and the remaining variables all show a positive promoting effect.</p>

<title>Comprehensive analysis of lifestyle (mediating variable)</title>
<p>It should be pointed out that in the process of exploring the influence mechanism of environmental perception on physical health status, the mediating variable&#x2014;lifestyle&#x2014;plays an important role. Therefore, we use multinomial Logit Models <xref ref-type="disp-formula" rid="E3">2</xref>, <xref ref-type="disp-formula" rid="E4">3</xref> to quantify this selection probability, in addition, some figures, tables, and random sampling cases are jointly employed to demonstrate the validity of the quantized results. During the model construction process, the first group is selected as the reference group, and its model parameters are set to 0. Based on the regression results in <xref ref-type="table" rid="tab2">Table 2</xref>, the coefficients of the utility functions of Models <xref ref-type="disp-formula" rid="E3">2</xref>, <xref ref-type="disp-formula" rid="E4">3</xref> are determined. By calculating the choice probabilities of 2006 samples in the scenarios of the mode and the mean value, the universality of the research conclusions is enhanced.</p>
<p>As shown in F1 of <xref ref-type="fig" rid="fig2">Figure 2</xref>, the mode statistical results of the seven lifestyles reveal the typical characteristics of residents&#x2019; living behaviors. The mode of Lifestyle<sub>1</sub> is 1, corresponding to a sample proportion of 70.68% (1,418 people), indicating that more than 70% of the respondents have less than 30&#x202F;min of high-intensity physical activities (with a significantly increased breathing rate) per week, which reflects from the side that under the background of the popularization of mechanized labor in China, the participation rate of residents in physical activities is relatively low. Based on the calculation of the multinomial Logit model, the choice probabilities of this lifestyle in the mode and mean value scenarios are 0.0142 and 0.0614 respectively, showing that residents have a weak willingness to maintain their health through physical labor.</p>

<p>The mode of Lifestyle<sub>2</sub> is also 1, corresponding to 31.25% of the samples, which means that approximately one-third of the respondents rarely engage in sweating or high-intensity exercises lasting more than 20&#x202F;min. Its choice probabilities under the mode and the mean value are 0.0142 and 0.1224 respectively, indicating that the awareness of residents to actively participate in physical exercise urgently needs to be improved. The mode of Lifestyle<sub>3</sub> is 1 (accounting for 70.68%), reflecting that most of the respondents lack regularity in their work; the choice probabilities calculated by the model are 0.0142 (mode) and 0.04 (mean value) respectively, suggesting that residents generally tend to avoid an irregular work pattern.</p>
<p>In contrast, the modes (4, 4, 4, 3) and means (3.381, 3.583, 3.558, 2.596) of Lifestyle<sub>4</sub>&#x2013;Lifestyle<sub>7</sub> are relatively high, indicating that residents have a good perception of social fairness and show positive performance in aspects such as sleep duration, leisure and relaxation, and social entertainment. The corresponding results of the multinomial Logit model show that the choice probabilities of these lifestyles are significantly higher than those of the previous three, confirming that residents are more inclined to relieve work pressure through sufficient sleep, leisure and relaxation, and social activities (<xref ref-type="fig" rid="fig2">Figure 2</xref>: F1&#x2013;F4).</p>
<p>Specifically, in the 4th subfigure F4 of <xref ref-type="fig" rid="fig2">Figure 2</xref>, the multinomial Logit model was employed to compute the selection probabilities of the seven lifestyles based on the mode and mean value of the variables. As illustrated by the results, under the mean-value scenario, the two lifestyles with the highest selection probabilities are &#x201C;sleep duration on workdays&#x201D; with 0.2452 and &#x201C;rest and leisure time&#x201D; with 0.2392. Therefore, Hypothesis H2 is supported.</p>

<title>Case testing and analysis based on random sampling</title>
<p>In Part (A) of Section 4.3, we analyzed the selection probability of residents&#x2019; lifestyles based on the full sample. The purpose of Part (B) in this section is to test and verify the results of Part (A). The sampling sources are regions with relatively high and relatively low economic development level, such as Beijing and Ningxia, Jiangsu and Guangxi, Zhejiang and Henan. Although the sample size of the sampling is small (3 individuals sampled in each group), the comparison is conducted in a random manner with three groups of data selected. Therefore, according to the principle of statistical inference, the test results have high credibility.</p>
<p>Based on the analysis of the overall sample, this part focuses on regional differences. Three individual questionnaires are randomly selected from the 10 environmental perception variables of the two sample sources, Beijing and Ningxia (the details of the samples are shown in <xref ref-type="table" rid="tab3">Table 3</xref>). By comparing the differences in lifestyle choices of individuals in different regions under the same environmental perception variables, the impact of the level of economic development on residents&#x2019; lifestyle preferences is explored.</p>

<p>Based on the calculation <xref ref-type="disp-formula" rid="E3">Equations 2</xref>, <xref ref-type="disp-formula" rid="E4">3</xref> of the multinomial Logit model, the probabilities of lifestyle choices for a total of 6 samples from Beijing and Ningxia were calculated in <xref ref-type="fig" rid="fig3">Figure 3</xref>. The study found that the three individuals in Beijing showed a high degree of consistency in the probability distribution of lifestyle choices: the probability of &#x201C;often taking a rest and relaxing in their free time&#x201D; was the highest, reaching 0.72; the probability of &#x201C;engaging in social and entertainment activities with friends (such as visiting each other, having meals, playing cards, etc.)&#x201D; was the second highest, indicating that residents in Beijing are more inclined to enrich their leisure time through leisure and relaxation and social activities; while the probability of &#x201C;psychological perception of social fairness&#x201D; was the lowest, only 0.0001, reflecting that this group has relatively limited attention to social fairness issues.</p>

</fig>
<p>The three individuals of Ningxia in <xref ref-type="fig" rid="fig3">Figure 3</xref> showed probability distribution characteristics similar to those of the samples in Beijing: the probabilities of choosing rest, relaxation, social and entertainment activities were high, while the attention to social fairness was low. The comparison between different regions shows that although Beijing is a developed region and Ningxia is located in the western part of China, there is no significant difference in the preferences for lifestyle choices between the residents of the two places. This result indicates that residents in regions with different levels of economic development in China have convergence in their lifestyle choices, and their action orientations may be less directly restricted by regional economic conditions.</p>
<p>To enhance the robustness of the research findings, we employed more sample cases to substantiate the universality of the results. From the perspective of economic development, based on data from Jiangsu and Guangxi, Zhejiang and Henan, we randomly selected three samples from each of these four provinces (totaling 12 samples) and applied the multinomial Logit model to calculate their selection probabilities. This approach was used to analyze whether residents from different geographical locations exhibit heterogeneity in their lifestyle choices. To facilitate easier comparison and intuitive presentation of the results, we visualized the findings in figures. In <xref ref-type="fig" rid="fig4">Figure 4</xref>, the lifestyle choices of the six sample individuals from Jiangsu and Guangxi, as well as the six from Zhejiang and Henan, are predominantly concentrated in &#x201C;L5, L6, L7,&#x201D; which represent leisure and relaxation, sufficient sleep, and social activities. Therefore, the results presented in <xref ref-type="fig" rid="fig3">Figures 3</xref>, <xref ref-type="fig" rid="fig4">4</xref> further corroborate the robustness and universality of this study&#x2019;s findings.</p>

<p>That is to say, among the given seven lifestyle options, &#x201C;leisure and relaxation,&#x201D; &#x201C;sufficient sleep,&#x201D; and &#x201C;social interaction activities&#x201D; are the most frequent choices made by residents to maintain their physical health.

<p>In the second column of <xref ref-type="table" rid="tab4">Table 4</xref>, the model coefficients show that different environmental perception variables have differential impacts on residents&#x2019; physical health. The positive influencing variables include WaterP (perception of water pollution), ExtWea (perception of extreme weather), PesFer (awareness of the harm of pesticides and fertilizers), GenCr (awareness of the harm of genetically modified crops), FoSaf (perception of food safety), and VegFru (perception of the availability of fresh vegetables and fruits). That is, residents effectively mitigate health risks by proactive measures against water pollution and extreme weather, cautious selection of foods to address pesticide residues and genetically modified ingredients, and enhance well-being by utilizing locally available fruits and vegetables.</p>

<p>Relatively speaking, the negative influencing variables include AirP (perception of air pollution), VehExh (perception of vehicle exhaust pollution), LivEnv (perception of the suitability of physical exercise places within 1&#x202F;km), and PubFac (perception of public facilities at the place of residence), indicating that the enhancement of these factors will not directly promote the improvement of residents&#x2019; health conditions. Regarding the negative regression coefficients, it is logically consistent: when individuals perceive more severe air pollution, vehicle emissions, or consider exercise facilities to be inconvenient or poorly maintained, such negative environmental exposures and perceptions (e.g., by reducing outdoor activities) can harm physical health. Therefore, it is natural for these perceptual variables to exhibit a negative correlation with physical health levels.</p>
<p>Thus, the results from the above presentation provide evidence for Hypothesis H3.</p>

<title>The influence effects based on Model <xref ref-type="disp-formula" rid="E6">5</xref></title>
<p>In the regression results of Model <xref ref-type="disp-formula" rid="E6">5</xref> (the 3rd column to the ninth column in <xref ref-type="table" rid="tab4">Table 4</xref>, namely <italic>j</italic>&#x202F;=&#x202F;1 to <italic>j</italic>&#x202F;=&#x202F;7), environmental perception variables show different health influence effects. The coefficients of ExtWea (perception of extreme weather), PesFer (awareness of the harm of pesticides and fertilizers), GenCr (awareness of the harm of genetically modified crops), FoSaf (perception of food safety), and VegFru (perception of the supply of vegetables and fruits) are positive, indicating that the improvement of these dimensions of environmental perception has a positive promoting effect on health. While the index coefficients of AirP (perception of air pollution), VehExh (perception of vehicle exhaust pollution), and PubFac (perception of public facilities) are all negative, suggesting that residents&#x2019; negative perceptions of air pollution and public facilities will suppress their health levels. Alternatively, when residents perceive the presence of air pollution, vehicle exhaust pollution, and poor exercise facilities, these factors are detrimental to physical health. Therefore, it is entirely reasonable that the model parameters for these perceptual variables exhibit negative values.</p>
<p>When the mediating variables are successively added as independent variables into Model <xref ref-type="disp-formula" rid="E6">5</xref>, the model coefficients of Lifestyle<sub>1</sub> (duration of high-intensity physical activities), Lifestyle<sub>2</sub> (regular physical exercise), and Lifestyle<sub>3</sub> (work regularity) are negative, revealing the potential health hazards of modern lifestyles. The results show that contemporary people have insufficient participation in physical activities, a low frequency of physical exercise, and more than half of the individuals have irregular working hours. These factors jointly lead to a negative impact on their health. On the contrary, the coefficients of Lifestyle<sub>4</sub> (perception of social fairness), Lifestyle<sub>5</sub> (sleep duration on working days), Lifestyle<sub>6</sub> (relaxation in free time), and Lifestyle<sub>7</sub> (social and entertainment activities) are positive, which reflect the health promotion mechanisms from the psychological and behavioral aspects respectively: the perception of fairness strengthens individuals&#x2019; social trust and sense of security, thus improving life satisfaction; sufficient sleep effectively restores the body&#x2019;s functions and improves cognitive and emotional stability; leisure and relaxation can relieve work pressure and maintain the balance of the body and mind; social and entertainment activities enhance individuals&#x2019; health resilience through emotional support and stress release. Based on the above results and analysis, Hypothesis H4 is naturally corroborated.</p>

<p>In Model <xref ref-type="disp-formula" rid="E6">5</xref>, by stripping away the multi-dimensional environmental perception variables, the analysis focuses on the influence effects of lifestyle on physical health status. Based on the questionnaire data of the seven lifestyles (Lifestyle<sub>1</sub> to Lifestyle<sub>7</sub>) and health status, the OLS regression method is used to complete the estimation of the model parameters. In order to more intuitively present the influence degree of each variable, the research results are presented in a visual form in <xref ref-type="fig" rid="fig5">Figure 5</xref>.</p>

<p>As shown in <xref ref-type="fig" rid="fig5">Figure 5</xref>, among various lifestyle factors, the &#x201C;monthly frequency of rest and relaxation&#x201D; (Lifestyle<sub>6</sub>) has the most significant impact on health. This means that regular rest and relaxation is an important way to relieve mental fatigue and adjust physical and mental states. In contrast, the impact of &#x201C;weekly duration of physical activity&#x201D; (Lifestyle<sub>1</sub>) is relatively weak, which indicates that most residents tend to choose low-intensity daily physical activities.</p>

<p>In the positive mediating path, psychological and leisure-related variables, mainly including the perception of social fairness, sleep duration, the frequency of leisure and relaxation, and the participation degree in social activities, exhibit a positive promoting effect. The research data shows that the effect values of the above variables are all positive, indicating that good environmental perception can significantly enhance residents&#x2019; cognitive awareness of social fairness, ensure sleep quality, and promote the development of leisure and social activities, ultimately having a positive impact on physical health. The mediating effect of perceived social equity and sleep duration is particularly prominent, which reflects that environmental improvement can significantly enhance residents&#x2019; health benefits.</p>
<p>In terms of the negative mediating path, variables related to physical activities and life regularity, mainly including the duration of high-intensity physical activities, the frequency of sweating-type exercise, and work regularity, show a significant negative mediating effect. The research results show that both the total effect and the direct effect between the level of environmental perception and the above variables are negative values. This indicates that when individuals perceive a deterioration in environmental quality, the likelihood of their participating in regular physical exercise and maintaining an orderly work rhythm is significantly reduced, which in turn has a negative impact on physical health, forming a transmission path of &#x201C;environmental pressure&#x2014;behavioral disorder&#x2014;health deterioration.&#x201D;</p>

<p><xref ref-type="table" rid="tab6">Table 6</xref> presents the regression results of Model <xref ref-type="disp-formula" rid="E7">6</xref>. Comparing the signs (positive/negative) of the regression coefficients with those of the corresponding variables in Model <xref ref-type="disp-formula" rid="E1">1</xref>, we observe that when <italic>j</italic>&#x202F;=&#x202F;1, only the coefficient sign of FoSaf is inconsistent, resulting in a 90% consistency rate for coefficient signs. When <italic>j</italic>&#x202F;=&#x202F;2, the consistency rate reaches 90%. At <italic>j</italic>&#x202F;=&#x202F;3, the rate drops to 60%, but it returns to 90% for <italic>j</italic>&#x202F;=&#x202F;4. For <italic>j</italic>&#x202F;=&#x202F;5, the consistency rate is only 20%, while for <italic>j</italic>&#x202F;=&#x202F;6 and <italic>j</italic>&#x202F;=&#x202F;7, it reaches 80%, respectively. Overall, the consistency rate of regression coefficient signs is 72.86% (excluding the constant term). These findings indicate that Model <xref ref-type="disp-formula" rid="E1">1</xref> exhibits reasonably good robustness.</p>

<p>Using 2006 sample data and the maximum likelihood method, the results of Model <xref ref-type="disp-formula" rid="E8">7</xref> are derived via the statsmodels library in Python, as presented in <xref ref-type="table" rid="tab7">Table 7</xref>. The regression results of Model <xref ref-type="disp-formula" rid="E8">7</xref> in <xref ref-type="table" rid="tab7">Table 7</xref> show exactly the same sign (positive or negative) as the corresponding coefficients of the second column in <xref ref-type="table" rid="tab4">Table 4</xref> for the independent variables of Model <xref ref-type="disp-formula" rid="E5">4</xref>. This means the independent variables have the same effect on the dependent variable in both Models <xref ref-type="disp-formula" rid="E5">4</xref>, <xref ref-type="disp-formula" rid="E8">7</xref>. Therefore, when we added the three core independent variables (Gender, Education Level, Economic Income) to Model <xref ref-type="disp-formula" rid="E5">4</xref> [that is, Model <xref ref-type="disp-formula" rid="E5">4</xref> is transformed into Model <xref ref-type="disp-formula" rid="E8">7</xref>], their impact on the dependent variable remained consistent. This confirms that Model <xref ref-type="disp-formula" rid="E5">4</xref> is robust.</p>

<title>Discussion</title>
<p>This study employs quantitative methods to examine the relationships among environmental perception, lifestyle, and residents&#x2019; health, using data from the Chinese General Social Survey (CGSS 2021). While the research yields significant academic value, it also presents inherent limitations and areas that necessitate critical reflection. It is worth noting that the selected variables and the acquisition of questionnaire data are both subjective, which impose certain conservatism and limitations on the research results. This should be specifically noted here.</p>
<sec id="sec24">
<label>5.1</label>
<title>Strengths of the research findings</title>
<p>In terms of academic contribution, the core strengths of this study are manifested in the seamless integration of theoretical frameworks and empirical analysis. Theoretically, it innovatively combines the Social Ecological Model with Protection Motivation Theory (PMT), transcending the simplistic causal relationship of &#x201C;environmental perception influencing health&#x201D; to construct a multi-level logical chain: &#x201C;micro-level individual cognition&#x202F;&#x2192;&#x202F;meso-level behavioral choices (lifestyle)&#x202F;&#x2192;&#x202F;macro-level health outcomes.&#x201D; Specifically, PMT is utilized to elucidate how environmental perception shapes health-related behaviors through two core dimensions: &#x201C;threat appraisal&#x201D; (e.g., risk assessments of extreme weather events and food safety hazards) and &#x201C;coping appraisal&#x201D; (e.g., enhancing health-related self-efficacy via regular sleep patterns and social engagement). Complementarily, the Social Ecological Model contextualizes these micro-level mechanisms by incorporating the supportive roles of macro-variables, such as community environmental governance and public service provision. This theoretical integration not only reinforces the validity of the research conclusions but also provides an integrated &#x201C;micro-meso-macro&#x201D; analytical paradigm for future studies in the field.</p>
<p>Empirically, the triangulation of research methods significantly enhances the robustness of the findings. Firstly, the multinomial Logit model is employed to quantify the probability of lifestyle choices, addressing the inadequacy of traditional linear models in handling &#x201C;categorical behavioral variables.&#x201D; This model enables the clear identification of probabilistic associations between distinct dimensions of environmental perception (e.g., positive perceptions of fresh produce availability, concerns about vehicle emissions) and lifestyle indicators (e.g., sleep quality, frequency of social interactions). Similarly, Shivam et al. (<xref ref-type="bibr" rid="ref26">26</xref>) used the Logit model to study the influence mechanism of daily activities and the surrounding environment on health. Secondly, the mediating effect model clarifies the &#x201C;intermediary role&#x201D; of lifestyle, confirming that environmental perception exerts an indirect impact on health through the sequential pathway: &#x201C;reducing psychological distress&#x202F;&#x2192;&#x202F;improving behavioral efficacy&#x202F;&#x2192;&#x202F;adopting healthy lifestyles.&#x201D; For example, Liu et al. (<xref ref-type="bibr" rid="ref27">27</xref>) explored physical activity as a mediator of the associations between neighborhood environments and the health status of Chinese older adults during the pandemic. Therefore, our study offers targeted insights for public health interventions, avoiding the myopic focus on either environmental governance or behavioral guidance in isolation.</p>

<title>Discussion on limitations of the research</title>
<p>We primarily discuss the research limitations from the following two aspects. On the one hand, the study exhibits constraints in variable comprehensiveness and measurement precision. Key confounding factors, such as individual-level predisposing conditions (e.g., chronic disease history), were omitted, potentially introducing bias in estimating the causality between environmental perception and lifestyle behaviors. Furthermore, the reliance on self-reported measures for health outcomes inherently incorporates systematic error, while incomplete operationalization of lifestyle constructs (e.g., absence of dietary pattern metrics) limits the robustness of mediating effect analyses. On the other hand, the analytical approach employed a multinomial Logit model on a limited sample (<italic>N</italic>&#x202F;=&#x202F;2,006), whereas extant methodologies [e.g., ordered Logit models in Zeng and Yang (<xref ref-type="bibr" rid="ref28">28</xref>)] suggest potential avenues for methodological refinement. Although cross-validation through stratified random sampling of six regions adhered to statistical inference principles, the restricted sample size remains susceptible to estimation inaccuracies arising from low-probability stochastic events.</p>

<title>Extended discussion</title>
<p>Without mediation analysis, a study may lack depth and fail to develop or test behavioral mechanisms theory. Even if regression analysis reveals a significant effect of environmental perception on physical health, the absence of mediation testing (e.g., through lifestyle) leaves the &#x201C;how&#x201D; unexplained. Does it operate by promoting/inhibiting physical exercise? Or by altering dietary habits? This critical process mechanism remains a &#x201C;black box.&#x201D; Therefore, investigating the relationship between environmental perception and physical health through the mediating variable (lifestyle) is both methodologically justified and substantively important.</p>

<title>Directions for improvement in future research</title>
<p>To address the aforementioned limitations, future studies can be optimized in three key areas. Firstly, data updates and model extensions are recommended: for example, adopting a &#x201C;two-way fixed effects model&#x201D; to control for time-invariant individual characteristics. Secondly, variable design should be refined: incorporating individual-level variables such as pre-existing medical conditions and macro-level variables such as healthcare policies, while expanding the measurement dimensions of &#x201C;lifestyle&#x201D; to enhance precision. Thirdly, causal identification should be strengthened: employing the &#x201C;instrumental variable (IV) method&#x201D;&#x2014;for instance, using &#x201C;the number of public parks within a community&#x201D; as an instrumental variable for environmental perception&#x2014;to mitigate endogeneity issues between &#x201C;environmental perception and health,&#x201D; thereby improving the validity of causal inferences.</p>

<title>Conclusion</title>
<p>The key conclusions are as follows: Descriptive analysis shows most residents are satisfied with their residential environment (air/water quality, extreme weather) but concerned about vehicle exhaust hazards; their lifestyle (sleep, leisure, social activities) is generally normal. Baseline regression confirms environmental awareness&#x2019; direct positive impact on physical health status: perceptions of extreme weather effects, pesticide/fertilizer hazards, GMO risks, food safety, and fresh produce accessibility significantly boost health, indicating positive environmental cognition benefits health maintenance. Unhealthy lifestyles exert a significant negative impact on health and become a key source of health risks, whereas Chen et al. (<xref ref-type="bibr" rid="ref29">29</xref>) and Lan et al. (<xref ref-type="bibr" rid="ref30">30</xref>) did not investigate the quantitative influence of lifestyle choice probability on health. The mediating effect model reveals lifestyle plays an important mediating role: positive environmental perception enhances social fairness, improves sleep quality, and promotes leisure/social participation, ultimately improving physical health. The core contribution of this paper lies in revealing the chain influence mechanism of &#x201C;environmental perception&#x2014;lifestyle&#x2014;physical health,&#x201D; and the practical significance is reflected in providing accurate data support for government environmental governance and community health intervention.</p>
