<title>Background</title>
<p>COVID-19 has affected mental health globally, increasing depression and anxiety. This study examined relationships between practicing COVID-19-related public health measures and depression and anxiety in young adult students.</p>
</sec>
<sec>
<title>Methods</title>
<p>A sample of 755 undergraduate students 18&#x02013;25 years of age at a large public university completed a cross-sectional survey in fall 2020 during the pandemic (response rate = 18.9%). The survey included demographic questions, anxiety and depression screeners (GAD-7 and PHQ-9), and questions on practicing public health measures (stay-at-home orders, quarantining, social distancing, etc.) since March 2020. Multivariate logistic regression was utilized to calculated adjusted odds between practicing public health measures and anxiety and depression.</p>
</sec>
<sec>
<title>Results</title>
<p>The majority of respondents reported practicing public health measures; however, 53% experienced anxiety (GAD-7 score <underline>&#x0003E;</underline>10) and 57% experienced depression (PHQ-9 score <underline>&#x0003E;</underline>10) in the 2 weeks prior to completing the survey. Participants who quarantined had significantly higher odds of anxiety (AOR = 1.44; 95% CL 1.07, 1.96) and depression (AOR = 1.77; 95% CL 1.30, 2.41) than those who did not. Participants who self-isolated also had significantly higher odds of anxiety (AOR = 1.53; 95% CL 1.13, 2.08) and depression (AOR = 1.87; 95% CL 1.37, 2.56) compared to those who did not. Moving/changing living situations in response to the pandemic also increased odds of depression (AOR = 1.86; 95% CL 1.33, 2.60).</p>
</sec>
<sec>
<title>Conclusion</title>
<p>Young adult undergraduate students experienced a high prevalence of anxiety and depression. Quarantining, self-isolating, and moving/changing living situations increased odds of anxiety and/or depression. The public health measures necessary for COVID-19 control and prevention may adversely affect mental health.</p>

<title>Introduction</title>
<p>In January 2020, the World Health Organization (WHO) declared COVID-19, the disease caused by the novel coronavirus SARS-CoV2, a public health emergency of international concern (<xref ref-type="bibr" rid="B1">1</xref>). The first case of the novel coronavirus was reported in the United States between December 2019&#x02013;January 2020 (<xref ref-type="bibr" rid="B2">2</xref>, <xref ref-type="bibr" rid="B3">3</xref>). It was not until March 19, however, that public health measures were implemented by individual states including stay-at-home orders, social distancing, and wearing masks or face coverings to control spread and to limit overwhelming hospital systems (<xref ref-type="bibr" rid="B4">4</xref>). In addition, quarantine and self-isolation periods were implemented under state-specific public health orders for individuals meeting criteria based on exposure and/or display of Covid-19 symptoms, like fever or chills (<xref ref-type="bibr" rid="B4">4</xref>). As COVID-19 spread through communities across the United States, institutions of higher education closed campuses and moved to remote learning modalities, displacing thousands of students (5).</p>
<p>The COVID-19 pandemic has had a global impact on mental health and well-ness (<xref ref-type="bibr" rid="B5">5</xref>). Evidence suggests adults under 45 years of age have been the most psychologically affected by lockdown measures, particularly due to loneliness and vulnerability to stress, financial distress, and sleep disturbances; (<xref ref-type="bibr" rid="B6">6</xref>) however, few studies have examined university students or young adults. Prior to the pandemic an estimated 41.6% of college students suffered from anxiety, and 36.4% were affected by depression (<xref ref-type="bibr" rid="B7">7</xref>). As of June 2020, the Centers for Disease Control and Prevention (CDC) reported that 75% of young adults 18&#x02013;24 years of age suffered from at least one mental or behavioral health symptom, and more than 25% had seriously contemplated suicide in the prior month (<xref ref-type="bibr" rid="B8">8</xref>). Other studies have also shown increased anxiety, depression, and suicidal ideation in college students due to the pandemic (<xref ref-type="bibr" rid="B9">9</xref>, <xref ref-type="bibr" rid="B10">10</xref>).</p>
<p>In university students, anxieties related to the pandemic may be exacerbated by practicing necessary public health measures and by changes in higher education such as closed campuses and online learning with limited face-to-face interaction with professors or peers (<xref ref-type="bibr" rid="B11">11</xref>). Extended quarantine and isolation periods are associated with psychological distress and other mental health-related concerns including decreased concentration, disrupted sleep patterns, feelings of unhappiness, loss of purpose, and substance use (<xref ref-type="bibr" rid="B12">12</xref>). In young adults, social support through peer networks is important and social isolation and loneliness due to the pandemic may impact mental health (<xref ref-type="bibr" rid="B13">13</xref>). Information on the relationship between practicing public health measures and mental health in undergraduate students is limited. The impact of public health measures on undergraduate students mental health is important to examine as colleges and universities continue to offer remote delivery courses.</p>
<p>This study explored relationships between practicing public health measures and anxiety and depression in a sample of undergraduate students 18&#x02013;25 years of age at a large public university. We hypothesized that practicing public health measures including social distancing, quarantining, self-isolation, and discontinuing to see family and friends would increase of anxiety and depressive symptomology.</p>

<title>Methods</title>
<sec>
<title>Participants and Recruitment</title>
<p>This investigation examined how the COVID-19 pandemic that necessitated public health measures, like quarantining and self-isolating, influenced anxiety and depression and undergraduate University students. As such, undergraduate students 18&#x02013;25 years of age enrolled at a large public university in the southwest United States in spring and fall 2020 were eligible for inclusion in this study. Students were recruited for 2 weeks in fall 2020 during a second wave of the COVID-19 pandemic. The study recruitment email was sent to 4,000 students, randomly selected to create a representative sample of the university&#x00027;s race/ethnicity and gender composition, Pell grant eligibility (an indicator of low-income status), and campus enrollment (at the main campus or at one of the university&#x00027;s branch campuses). Participants provided consent by starting the survey. The study was approved by the university&#x00027;s Institutional Review Board and conformed to principles embodied in the Declaration of Helsinki. Results will be disseminated to participants through the university.</p>
</sec>
<sec>
<title>Instruments</title>
<p>Data were collected <italic>via</italic> Opinio, a secure online survey tool used by the university for research (<xref ref-type="bibr" rid="B14">14</xref>). The survey included screening questions assessing the potential participants&#x00027; age and student status. The survey then included demographic questions (age, race/ethnicity, gender, sexuality, academic standing, Pell grant eligibility, employment); the seven-item Generalized Anxiety Disorder Scale 7 (GAD-7), (<xref ref-type="bibr" rid="B15">15</xref>) a validated measure of anxiety in the past 2 weeks; the Patient Health Questionnaire 9 (PHQ-9), (<xref ref-type="bibr" rid="B16">16</xref>) a validated measure of depression in the past 2 weeks; and questions on COVID-19 testing and practicing public health measures (i.e., stay at home orders, social distancing, wearing a mask or face covering) since the start of the pandemic in March 2020.</p>
</sec>
<sec>
<title>Data Analysis</title>
<p>Responses to survey questions were not required; however, only participants who responded to questions on public health measures were included in data analysis. All data analyses were performed using Statistical Analysis Software (SAS) Version 9.4. Demographic data are presented descriptively (mean, standard deviation, frequency, percentage). The GAD-7 and PHQ-9 were scored according to standard guidelines. Means and standard deviations (SD) were calculated for each instrument for the full sample and by demographic subgroups. Raw GAD-7 scores were dichotomized to anxiety (score <underline>&#x0003E;</underline>10) or no anxiety (score &#x0003C;10) (<xref ref-type="bibr" rid="B15">15</xref>, <xref ref-type="bibr" rid="B17">17</xref>). Raw PHQ-9 scores were dichotomized to depression (score <underline>&#x0003E;</underline>10) or no depression (score &#x0003C;10) (<xref ref-type="bibr" rid="B16">16</xref>). The prevalence of anxiety and depression were calculated for the full sample.</p>
<p>Participants also indicated if seven public health measures applied to them during the COVID-19 pandemic, since March 2020. The following measures were assessed dichotomously (&#x0201C;no&#x0201D; = 0 or &#x0201C;yes&#x0201D; = 1): staying at home due to stay at home orders, quarantining, self-isolating, practicing social distancing (staying at least six feet from others), wearing a mask/face covering, moving/changing living situation, continuing to see family and friends, or making no changes.</p>
<p>The frequency and percent of participants reporting anxiety (GAD-7 score <underline>&#x0003E;</underline>10) and depression (PHQ-9 score <underline>&#x0003E;</underline>10) were calculated for those reporting practicing vs. not practicing each public health measure. Differences in anxiety and depression as binary variables (present or not present) were assessed using Fisher&#x00027;s exact tests (<italic>P</italic> &#x0003C;0.05 indicated statistical significance). All demographic variables (age, gender, race/ethnicity, sexuality, employment status, and Pell grant eligibility) were considered candidates for inclusion as Co-variates in multivariate models. To determine Co-variates, raw GAD-7 and PHQ-9 scores were compared between demographic subgroups utilizing analysis of variance (ANOVA). A <italic>P</italic>-value &#x0003C;0.20 was used to determine Co-variates for inclusion in logistic regression analyses, opposed to <italic>P</italic> &#x0003C; 0.05 because traditional levels of <italic>P</italic> &#x0003C; 0.05 can fail in identifying variables known to be important (<xref ref-type="bibr" rid="B18">18</xref>).</p>
<p>Multivariate logistic regression was utilized to calculate adjusted odds ratios (AOR) between practicing public health measures and anxiety (GAD-7 score <underline>&#x0003E;</underline>10) and depression (PHQ-9 score <underline>&#x0003E;</underline>10) as separate outcomes. 95% Wald Confidence Limits were also calculated for AORs.</p>

<title>Results</title>
<p>Recruitment emails were sent to 4,000 randomly selected students in October 2020. Eight-hundred fifty-two individuals started the survey. Of those, 97 were excluded (23 did not meet inclusion criteria, five reported an age outside the age range, and 69 did not answer questions regarding public health measures). The final sample included 755 participants, yielding a response rate of 18.9%.</p>
<p>The average age of participants was 21.3 &#x000B1; 1.6 years. Shown in <xref ref-type="table" rid="T1">Table 1</xref>, the majority were 21&#x02013;25 years of age (<italic>n</italic> = 499; 66.4%); female (<italic>n</italic> = 461; 61.4%); and White (<italic>n</italic> = 239; 31.7%) or Hispanic, Latino, or Spanish (<italic>n</italic> = 218; 28.9%). The majority reported heterosexual (<italic>n</italic> = 519; 69.0%) or bisexual (<italic>n</italic> = 84; 11.2%) sexual orientation. Sixty-one percent were employed at the time of taking the survey, either full-time or part-time. Over half of participants were eligible for Pell grants (<italic>n</italic> = 377; 50.1%), an indicator of low-income status. Most participants reported they had not been tested for COVID-19 since March 2020 (<italic>n</italic> = 470; 62.3%). Of those that had been tested (<italic>n</italic> = 285; 37.7%), 94% (<italic>n</italic> = 267) tested negative.</p>

<title>Discussion</title>
<p>Young adults and undergraduate students were particularly at risk for mental health distress during COVID-19 (<xref ref-type="bibr" rid="B5">5</xref>, <xref ref-type="bibr" rid="B8">8</xref>&#x02013;<xref ref-type="bibr" rid="B10">10</xref>, <xref ref-type="bibr" rid="B19">19</xref>). Research exploring impacts of following public health measures (e.g., stay at home orders, social distancing, wearing a mask or face covering) on mental health during the COVID-19 pandemic is limited (<xref ref-type="bibr" rid="B12">12</xref>, <xref ref-type="bibr" rid="B19">19</xref>&#x02013;<xref ref-type="bibr" rid="B21">21</xref>). Extant research conducted earlier in the pandemic suggests anxiety and depression increased in university students due to COVID-19 (<xref ref-type="bibr" rid="B9">9</xref>). This study suggests a high prevalence of anxiety and depression in students and significant associations between practicing public health measures and mental health.</p>
<p>In the United States, the CDC advised institutions of higher education to apply public health measures ranging from remote educational delivery to closing campuses (<xref ref-type="bibr" rid="B22">22</xref>). In this sample of undergraduate students 18&#x02013;25 years of age, over half experienced anxiety or depression in the past 2 weeks (53 and 57%, respectively), 45% experienced both, and 10% reported serious suicidal ideations in the past month. Those who reported practicing certain public health measures had a significantly higher prevalence of depression. For example, since March 2020, 64% of those who reported quarantining, 66% of those who reported self-isolating, and 67% of those who moved or changed living situations experienced depression based on PHQ-9 scores. Participants who reported quarantining, self-isolating, or moving or changing living situations had higher odds of anxiety and/or depression. Those who quarantined had 1.4 times the odds of anxiety and nearly 1.8 times the odds of depression compared to those who did not quarantine. Participants who reported self-isolating since March 2020 had 1.5 times the odds of anxiety and nearly 1.9 times the odds of depression compared to those who did not self-isolate. Moving or changing living situations also increased the odds of depression nearly 1.9 times. Prior research also suggests public health quarantines increase psychological distress like depression, with mental health distress increasing with quarantine length (<xref ref-type="bibr" rid="B20">20</xref>, <xref ref-type="bibr" rid="B21">21</xref>).</p>
<p>Findings from this study are similar to recently published studies (<xref ref-type="bibr" rid="B12">12</xref>, <xref ref-type="bibr" rid="B19">19</xref>&#x02013;<xref ref-type="bibr" rid="B21">21</xref>). In June 2020, the CDC reported 49.1% of young adults 18&#x02013;24 years of age had anxiety disorder, 52.3% had depressive disorder, and 62.9% had anxiety or depressive disorder (<xref ref-type="bibr" rid="B8">8</xref>). This study, conducted in October-November 2020, shows a similar and even slightly higher prevalence with 64.5% experiencing anxiety or depression. In this sample, 10.5% reported serious thoughts about ending their life in the past month, a lower estimate than CDC&#x00027;s report of 25.5% in young adults 18&#x02013;24 years of age (<xref ref-type="bibr" rid="B8">8</xref>). Because suicide is the second leading cause of death among young adults, (<xref ref-type="bibr" rid="B23">23</xref>) there is a critical need to assess suicidal thoughts and implement preventive measures in young adults during the pandemic, given the increase in anxiety, depression, and other mental health concerns.</p>
<p>Academic performance was not captured in the current study and is a possible co-factor in the linkage between mental health outcomes and COVID-19 public health measures (<xref ref-type="bibr" rid="B24">24</xref>). Specifically, the alterations in study behaviors (e.g., studying in isolation vs. in a social gathering) and delivery of course content (e.g., shift from in-person instruction to online formats) due to lockdown measures increased likelihood of poor academic performance and thus mental health decline (or vice versa) (<xref ref-type="bibr" rid="B24">24</xref>). Moreover, students who reported lower academic concerns and levels of anxiety and depression were less likely to dropout during the COVID-19 pandemic (<xref ref-type="bibr" rid="B25">25</xref>, <xref ref-type="bibr" rid="B26">26</xref>). We were unable to measure the impact of academic performance on reported outcomes, and is thus one limitation to the study.</p>
<sec>
<title>Limitations</title>
<p>Limitations of this study include the cross-sectional design employed. While this approach cannot track long-term effects of COVID-19 associated public health measures on undergraduate students&#x00027; mental health, it offers necessary data to target current mental health of young adults. Generalizability is also limited. The sample size was large enough to produce significant results, however findings from undergraduate students 18&#x02013;25 years cannot be generalized across age groups. Last, while demographics were limited, the sample mirrored the ethnic diversity of the university (23% identified as more than one race).</p>

<sec>
<title>Implications</title>
<p>The COVID-19 pandemic has adversely affected university students&#x00027; mental health (<xref ref-type="bibr" rid="B27">27</xref>). Over half of participants experienced anxiety or depression in the past 2 weeks and 10% reported serious suicidal ideations in the past month. Quarantining, self-isolating and changing living situations significantly increase the odds of anxiety and/or depression. These results are critical to universities to ensure mental health services are available to students including telehealth and crisis counseling. Colleges and universities must continue mental health outreach and services to college students beyond this international pandemic (<xref ref-type="bibr" rid="B27">27</xref>, <xref ref-type="bibr" rid="B28">28</xref>).</p>
