University students are particularly vulnerable to such disruptions and maybe particularly disposed to suicidal ideation, potentially creating a new public health crisis. The study aimed to assess suicidal ideation and associated factors among university students in Bangladesh during the early stages of the COVID-19 pandemic. A cross-sectional online survey was conducted using the Google form (Google survey tool) from March to April 2020. Initially, 3366 respondents voluntarily completed the survey form. Finally, 3331 surveys were included in the final analyses after removing incomplete surveys. The data ware reviewed, rechecked, and analyzed with SPSS (25.0 version) software. A total of 1979 (59.4%) males and 1352 (40.6%) females participated. Respondents were between the ages of 18 to 28 years (mean age 21.4 years [SD=1.9]). The prevalence estimate of suicide ideation was 12.8%. Potential risk factors included less sleep, excess sleep, cigarette smoking, past suicidal thoughts, suicidal attempt history, family history of suicidality, depression, anxiety, and stress. Potential protective factors included being male, having lower SES, living in rural areas, regular physical exercise, and satisfactory study. Suicidal ideation is prevalent among Bangladeshi university students during the onset of the COVID-19 pandemic. Understanding the correlates of suicidal ideation may aid to develop targeted strategies to support students during and after the COVID-19 pandemic. The world is facing a severe pandemic with no reliable prediction of its duration. Bangladesh reported the first three cases of COVID-19 in March 08, 2020 (Islam, Emran, et al., 2020; Tasnim et al., 2020) . To alleviate the spread of the potentially fatal disease, the government of Bangladesh declared a "lockdown" on March 26, 2020, with closures of educational institutions and enforced maintenance of strict social isolation (Bdnews24.com, 2020; Ferdous et al., 2020) . Nonetheless, steep rises in COVID-19 cases were observed in April 2020 (Dhaka Tribune, 2020) . The imposition of isolation and quarantine hindered social activities, and the situation created psychological fears and the potential for vulnerable citizens to contemplate suicide (Thakur & Jain, 2020) . Pandemic issues, such as spatial or physical distancing, isolation, and quarantine, as well as occupational, educational, and economic impacts, may generate psychological distress including sadness, depression, anxiety, fear, anger, annoyance, frustration, guilt, hopelessness, boredom, and panic Mazza et al., 2020; Thakur & Jain, 2020) . Many people experience these features of mental health problems during and after crises like the COVID-19 pandemic (Banerjee, 2020) , and these may contribute to suicidal ideation. People may experience on average 0.205 years of life lost due to psychosocial consequences of COVID-19-related mitigation measures (Moser et al., 2020) . Strict spatial isolation and mass home quarantining may have long-lasting effects on student psychological well-being (Brooks et al., 2020) , and isolation among prisoners in Italy has been associated with two-to four-fold elevated rates of suicide (Roma et al., 2013) . Moreover, to obtain relief from negative mood states and experiences, individuals may initiate or increase participation in potentially addictive behaviors (e.g., tobacco use, heavy drinking, and illicit drug use) that are also associated with suicidal ideation and behavior among adolescents (Wilcox, 2004) and adults (Esang & Ahmed, 2018) , with risk of death by suicide 10 to 14 fold higher in individuals using substances or with substance use disorders (Wilcox et al., 2004) . Early adulthood (e.g. from 18-30 years) appears to be a particularly vulnerable developmental epoch for suicidal ideation (Arafat, 2019) . Findings from a previous study suggested high levels of anxiety and depression among Bangladeshi students early in the COVID-19 pandemic , and these factors may lead to suicidal ideation (Czeisler et al., 2020) . However, the extent to which students may experience suicidal ideation during the pandemic is not well understood. Suicidal ideation is prevalent among university students, with estimates of 6.3% noted in American students and 13.8% among Bangladeshi students (Eisenberg et al., 2013; Rahman, Islam, Mamun, et al., 2020) . The latter study also associations between suicidal ideation and female gender, being a fifth-year student, being of lower socioeconomic status, having experienced traumatic events, having a family history of suicide, and depression (Rahman, Islam, Mamun, et al., 2020) . Suicidal ideation, which is considered an identifiable and modifiable risk factor for suicidal behavior, is important to identify for suicide prevention (Mann et al., 2005; Zalsman et al., 2016) . The elevated prevalence of suicidal ideation among university students has been associated with depression, drug use problems, sleep problems, and being overweight (Ashrafioun et al., 2016) . Such factors (e.g., depression, stress, posttraumatic stress symptoms, mood alterations and irritability, emotional disturbances, emotional exhaustion, insomnia, anger) are prevalent among individuals who have been quarantined (Serafini et al., 2020) . Potential risk factors for suicidal ideation in university students may include psychopathological symptoms such as depression and anxiety (Arria et al., 2009; Gulec Oyekcin et al., 2017; Mann et al., 2005; Sareen et al., 2005) . During the COVID-19 pandemic and with isolation and quarantine, there may be increases in suicidal ideation and behaviors among at-risk populations . The first suicide case (male; age 36 years) reported in Bangladesh related to the fear of COVID-19 occurred on March 25, 2020 . Later, another case report identified eight apparent suicides in Bangladesh during the COVID-19 pandemic in April, 2020 (Bhuiyan et al., 2020) . Students' psychological well-being may be disrupted by not only having strict spatial isolation imposed, but also by future career uncertainty. Hence, university students may be at particular risk of contemplating suicide during the outbreak. Here, we sought to examine the prevalence and correlates of suicidal ideation among Bangladeshi university students in a nationwide survey early during the COVID-19 pandemic. We hypothesized that suicidal ideation would be prevalent and would exceed the 13.8% estimate previously observed in Bangladeshi students (Rahman, Islam, Mamun, et al., 2020) , and would be more prevalent among females as compared with males. Further, we hypothesized positive correlations between suicidal ideation and mental health concerns (e.g., depression and anxiety) and negative correlations with measures of positive health (good sleep, regular exercise, and selfreported satisfaction with studies). The present survey was cross-sectional and conducted from April to May, 2020. The study included 3,331 respondents from more than 100 universities (including public, private, and national universities located in different administrative units of Bangladesh). This study's target population was university students who were enrolled in various subject areas at different universities in Bangladesh. Inclusion criteria were being (i) a university student, (ii) aged 18 years or older, and (iii) able to read and understand Bangla. Exclusion criteria included (i) students who were under 18 years of age, and (ii) those who did not complete the entire survey. A self-reported questionnaire written in Bangla (participants' native language) was employed to collect data during the survey. After depositing all questions in Google form, a shareable link was generated. An internet-based survey was conducted using the Google survey link shared across different online platforms available to university students (e.g., university students' Facebook groups, online students' forums, and university blogs). During informed consent, a specific indication was made of our interest to assess suicidal ideation in relation to the COVID-19 pandemic among university students. Moreover, the name of participants' universities was queried during the survey. A pilot test was conducted on 50 samples before inaugurating final data collection. These pilot data were excluded in subsequent analyses. Initially, 3,366 individuals submitted survey responses after providing informed consent. Of these, 3,331 respondents (97.5%) completed the entire survey voluntarily and anonymously. Duplicate respondents were controlled using google survey tools' default system that allowed a participant in a single time to fill up the survey form after signing in using his/her google account. A self-reported virtual questionnaire containing informed consent along with four sections assessing socio-demographic, behavioral, suicidal, and psychological factors, was employed to conduct the survey. In the informed consent, a specific indication was made of COVID-19 and our interest in assessing suicidal ideation and mental states in relation to the COVID-19 outbreak and the ensuing public health measures. Socio-demographic data were collected during the survey including age, gender, marital status, family type (nuclear/joint, with joint families being extended and often including multiple generations), monthly family income, and living area (urban/rural). Socio-economic status (SES) was categorized into three classes: lower, middle, and upper based on monthly family income of less than 15,000 Bangladeshi Taka (BDT) ≈ 177 US$, 15,000-30,000 BDT ≈ 177-354 US$, and more than 30,000 BDT ≈354 US$, respectively (Rahman, Islam, Bishwas, et al., 2020; Rahman, Islam, Mamun, et al., 2020) . The intra-class correlation coefficient (ICC) of socio-demographic measures was 0.24. Behavioral measures were collected during the survey by asking questions concerning physical exercising (yes/no), average sleeping hours, satisfaction regarding academic studies (yes/no), and cigarette smoking (yes/no) in relation to the COVID-19 outbreak. Sleeping hours were classified into three categories on the basis of average daily sleeping hours and classed as normal (7-9h), less than average (<7h), or more than average (>9h) based on (Hirshkowitz et al., 2015; . The overall ICC of behavioral measures was -0.02. Suicidal measures were recorded during the survey by asking 'yes/no' questions concerning suicidal ideation, past suicidal thoughts, history of suicide attempts, and family members' suicidal history. With regard to assessing suicidal ideation, respondents were asked the following: "During the COVID-19 outbreak, have you ever seriously thought about killing yourself?". The construction of this question was based on previous studies that assessed suicidal ideation: "During the past 12 months, have you ever seriously thought about killing yourself?" (Begum et al., 2017; Pandey et al., 2019; Santos et al., 2017) . Family history of suicide was assessed using the question, "Has anyone in your family committed suicide?". In addition, "Have you ever seriously thought about killing yourself?", and "Have you ever attempted to kill yourself?" were asked during the survey to assess lifetime suicidal thoughts and suicide attempt history, respectively; these have been recently used in a study of university students (Abdu et al., 2020) . The overall ICC of suicidal measures was -0.11. The present study used the Depression, Anxiety and Stress Scale (DASS-21: Lovibond & Lovibond, 1995; Bangla version: Alim et al., 2017) to assess depression, anxiety, and stress. The DASS-21 is widely in epidemiological surveys. This scale consists of 21 questions including three subscales: 7 items each for depression, anxiety, and stress, with each question scored along a four-point Likert scale ranging from 0 ("never") to 3 ("always") (Lovibond & Lovibond, 1995) . In the present study, moderate to severe or extremely severe scores were used to categorize levels of depression, anxiety, and stress, using the following cutoffs: depression≥14, anxiety≥10, and stress≥19 (Alim et al., 2017) . In the present study, the overall Cronbach's alpha of DASS-21 was 0.94 (for depression, anxiety, and stress subscales were 0.86, 0.86, and 0.86, respectively). The overall ICC of DASS-21 was 0.94. Data were analyzed using Microsoft Excel 2019 and SPSS software version 25.0. Microsoft Excel was used for editing, sorting, and coding. The excel file was then imported into SPSS software. Descriptive statistics (frequencies, percentages, means, standard deviation) and some analyses (i.e., chi-square tests, reliability tests) were performed using SPSS software. Logistic regression (both unadjusted and adjusted models) was performed with a 95% confidence interval to determine significant associations between categorical dependent and independent variables. Analyses were univariate, yielding crude odds ratios (CORs), followed by multivariable analyses with predictors (only significant variables from unadjusted model) combined in the models, and yielding adjusted odds ratios (AORs). The association of variables was considered statistically significant if the two-sided p-value was less than 0.05. All procedures of the present study were performed in accordance with the Institutional Research Ethics and the Declaration of Helsinki. The study was approved by Biosafety, Biosecurity, and Ethical Clearance Committee, the ethical review board of the Faculty of Biological Sciences, Jahangirnagar University, Savar, Dhaka-1342, Bangladesh (Ref No: BBEC, JU/ M 2020/COVID-19/(8)6). After providing digital consent, respondents completed the survey form. The consent form specifically outlined the aims, objectives, nature, and procedure of the study and stated clearly the right to withdraw data from the survey at any time. A total of 3,331 respondents were recruited into the final analyses; 59.4% were male, the mean age was 21.4 years (SD=1.9) and ranged between 18-28 years, and almost all respondents were unmarried (82.1%). Most were from nuclear families (81.8%), and the majority were from the higher SES group (50.3%) and came from urban areas (68.0%) ( Table 1 ). More than half of respondents (55.6%) did not engage in physical exercise, and most (73.0%) slept in a normal range (7-9 hours). Additionally, most did not smoke cigarettes (81.1%), and did not have satisfactory feelings regarding their studies (62.4%) during the COVID-19 outbreak. A sizable minority of respondents (12.8%) had suicidal ideation during the COVID-19 outbreak, and 18.0% of respondents reported past suicidal thoughts during pre-COVID-19 times. Additionally, a sizable minority reported prior suicidal attempts (6.6%), and 3.2% reported a family history of suicide. Based on the psychometric scale, the findings revealed that the majority (63.0%, 63.9%, and 58.9%) of respondents experienced depression, anxiety, and stress, respectively. Proportions of respondents with suicidal ideation during the COVID-19 were higher in (i) females versus males, (ii) respondents aged 21-23 years versus 18-20 years, (iii) respondents from higher SES versus lower SES families, (iv) respondents living in urban versus rural areas, (v) respondents not regularly versus regularly exercising, (vi) respondents sleeping less than normal (<6 hours) versus a normal range (7-9 hours), (vii) respondents sleeping more than normal (>9 hours) versus a normal range (7-9 hours), (viii) respondents with cigarette smoking versus without, (ix) respondents with unsatisfactory versus satisfactory feelings about their studies, (x) respondents with versus without past suicidal thoughts, (xi) respondents with versus without suicidal attempt histories, (ⅻ) respondents with versus without familial suicidality, (ⅹⅲ) respondents with versus without considerable depression, (ⅹⅳ) respondents with versus without considerable anxiety, and (ⅹv) respondents with versus without considerable stress. Univariable regression analysis was performed to assess potential risk and protective factors for suicidal ideation (Table 2) . Males were 0.75 times less likely to have suicidal ideation than females. Additional protective factors of suicidal ideation were individuals from lower vs. higher SES; individuals from middle vs. higher SES; individuals living in rural vs. urban areas; individuals with vs. without regular exercise; and individuals with vs. without having satisfactory feelings regarding their studies. Respondents sleeping fewer than normal hours were 3.25 times more likely to have suicidal ideation than those sleeping a normal range. Additional potential risk factors of suicidal ideation included more than normal vs. normal sleep; smoking vs. non-smoking status; individuals with vs. without past suicidal thought; individuals with vs. without suicidal attempt history; individuals with vs. without suicidal family suicidal history; individuals with versus without considerable depression; individuals with versus without considerable anxiety; and individuals with versus without considerable stress. Multivariable analyses with predictors (only significant variables from unadjusted model) entered together in the model revealed that most factors remained significant, with only gender losing statistical significance (see Table 3 ). Our study hypotheses were partially supported. According to this study's findings, 12.8% of students had suicidal ideation during the COVID-19 pandemic, 18% had past suicidal thoughts, and 6.6% had prior suicide attempts. Factors significantly associated with suicidal ideation included less sleep, more sleep, cigarette smoking, past suicidal thoughts, suicide attempt history, family history of suicidality, depression, anxiety, and stress. Suicidal ideation was less prevalent among male students, although gender was no longer significant in multivariate analyses. Further, lower SES, less regular physical exercise, and not having satisfactory feelings about one's academic studies were associated with suicidal ideation. Implications are discussed below. University students are important for a country's future. Suicidal ideation during this pandemic should be addressed to prevent premature ending of life. With regard to suicide in Bangladesh, this study presents an assessment of suicide ideation students across universities in Bangladesh soon after the COVID-19 outbreak. Despite variations across surveys involving populations studied, methods and cultures, the current findings may be compared with those from prior studies investigating suicidal ideation and related factors among students and other populations. We observed the prevalence of suicidal ideation during early stages of the COVID-19 pandemic to be 12.8%, and the prevalence of lifetime time suicidal thoughts to be 18.0%. A prior Bangladeshi study conducted during pre-COVID-19 period reported 13.8% prevalence of suicidal ideation among university students over the past 12 months (Rahman, Islam, Mamun, et al., 2020) . In contrast, one earlier Bangladeshi study showed a 5% prevalence estimate of suicidal ideation among (rural) youth (Begum et al., 2017) , and an 11.7% prevalence estimate was found in another study among school-going adolescents in Bangladesh (Khan et al., 2020) . Another study (conducted across 17 countries) showed a 9.2% prevalence of suicidal ideation (Nock et al., 2008) . Some studies have reported prevalent suicidal ideation (22.5%) among adolescent high school students in Ethiopia pre-COVID-19 (Amare et al., 2018 ). An international study reported lifetime prevalence of suicidal ideation among students to be 12.6% (Pereira & Cardoso, 2015) , which is comparable to the current findings. A prior study in Ethiopia among university students found lifetime prevalence of suicidal ideation to be 58.3% (Abdu et al., 2020) . These prior studies were not conducted at the time of COVID-19 pandemic, and further studies (especially longitudinal ones that directly assess relationships with COVID-19 factors) are needed to examine the potential impact of this pandemic on suicidal thoughts and behaviors (Klomek, 2020) . Many students in this study had suicide-attempt histories (6.6%), and these appear higher than those from a meta-analysis of college students conducted in China (pooled prevalence was 2.8% with ranging from 0.4% to 10.5% ) (Yang et al., 2015) , and another study of university students in Ethiopia (4.4%; Abdu et al., 2020) . However, in other studies (before COVID-19), suicide attempt prevalence was higher, at 7.1% among Turkish college students (Toprak et al., 2011) , and 16.2% among high school students in Ethiopia (Amare et al., 2018) . As such, longitudinal studies are needed given that suicide attempts may take time to occur, and interventions currently appear warranted to help prevent such events. Suicidal ideation was higher among people with depression, anxiety, and stress. Similar findings have been observed previously (Levy et al., 2019) , prior to COVID-19, similar to relationships between anxiety and suicidality found in another Bangladeshi study (Khan et al., 2020) . Also, strong associations between suicidal ideation and depression were seen in prior studies among Bangladesh university students (Pervin & Ferdowshi, 2016; Rahman, Islam, Mamun, et al., 2020) , resonating with research among adolescents in Germany linking suicidality with depression/anxiety (Brunner et al., 2007) . Several studies suggest that females are more vulnerable to suicidal thoughts than males (Begum et al., 2017; Borges et al., 2008; Brunner et al., 2007; Donath et al., 2014 Donath et al., , 2019 Kaess et al., 2011; Nock et al., 2008; Pereira & Cardoso, 2015; Rahman, Islam, Mamun, et al., 2020) . Some studies have found no link between gender and suicidal ideation (Amare et al., 2018) . The current findings are in line with these studies in that suicidal ideation was more prevalent among females, and this finding no longer remained significant in multivariate models, suggesting that other factors (e.g., anxiety, depression, stress) may in part account for this relationship. The current research revealed a significant relationship between suicidal ideation and sleeping problems, smoking, and dissatisfaction with studies. These findings resonate with those from previous studies (Begum et al., 2017; Dolsen et al., 2020; Donath et al., 2014; Khader et al., 2020) . The current research also indicated associations between physical exercise and suicidal ideation, similar to prior reports (Becker et al., 2018) . Prior studies have associated poor physical exercise with depression and anxiety (Carek et al., 2011; and suggest that physical exercise may reduce depression (Dinas et al., 2011) . Future studies should examine relationships among these domains longitudinally. This study found a significant relationship between suicidal ideation and socioeconomic status: students from higher SES families had more suicidal ideation than those from lower SES families, similar to prior findings among adolescents (Kokkevi et al., 2012) . Lower SES backgrounds appeared to be protective in this study. This finding differs from that in a prior Bangladeshi study, which indicates that suicidal ideation was higher among university students (Rahman, Islam, Mamun, et al., 2020) and adolescents from lower SES groups (Begum et al., 2018) . A study in Brazil also seemingly reported different findings (Santos et al, 2017) , similar to other studies linking lower SES to suicidal ideation (Goodman et al., 2017; Ju et al., 2016) . The extent to which the present findings are related to Bangladesh culture, student samples, COVID-19, or other factors warrants more study. Suicidal family history was found to correlate with suicidal ideation in this study, similar to a prior study conducted among a community sample (Lee et al., 2010) and among university students (Santos et al, 2017) . Family suicide background may elicit negative emotions, and related psychological pain may lead to suicide ideation (Mento et al., 2020) . This study also found that individuals living in urban versus rural areas appeared more prone to suicidal ideation. These findings resonate with a study of Chinese students that observed a correlation between rural living and suicidal ideation (Meng et al., 2013) . This study assessed suicidal ideation during the onset of the COVID-19 outbreak among university students in Bangladesh. The study observed a high prevalence of suicidal ideation and raises the possibility that COVID-19 may be having emotional and psychological impacts on university students. Associations with demographic and potential risk and protective factors demonstrated similarities with previous studies. Future studies should examine directly possible relations with COVID-19, monitor changes over time, and test the efficacies of mental health interventions. In the interim and in order to promote better mental and overall health, students should strive to comply with health recommendations during the COVID-19 pandemic Király et al., 2020) . General recommendations may include a daily routine involving adequate sleep and appropriate exercise, maintaining hydration and personal hygiene, engaging in relaxing and social activities, making/taking personal time and staying informed about current health information (Király et al., 2020) . Limitations should be noted. First, the research was cross-sectional, so causality cannot be determined. Second, self-report measures were used, and these have potential biases including with respect to social desirability and declarative memory. However, the study's online format may have increased the veracity of responses compared to offline and/or faceto-face surveys, although this notion is largely speculative. Third, this research may not be regarded as representative due to the online survey using s nonprobability sampling. Moreover, suicidal ideation was measured using a single-item question with a binary response rather than a validated instrument. Likewise, non-suicidal self-injury, an important factor linked to suicidal ideation and behaviors, was not assessed in this study, and future studies should assess non-suicidal self-injury. Over one in eight university students reported suicidal ideation during the COVID-19 pandemic. The findings provide important baseline information on suicidal ideation among Bangladeshi university students during the COVID-19 pandemic. Students' mental health concerns, especially depression, were strongly correlated with suicidal ideation during the COVID-19 pandemic. Effective strategies are needed to support the mental health of students. Students should be aware of treatment options available to them during the COVID-19 pandemic. The extent to which specific awareness programs or counseling efforts may be developed and enacted to promote mental health and prevent suicidal ideation and behaviors during and following the pandemic warrants examination. study evidence from media reports.
