RESUMO

BACKGROUND: Research is scarce on the prospective predictors of first onset suicidal thoughts and behaviors (STB) and the accuracy of these predictors in university students, particularly in low-and-middle income countries. Therefore, we assessed the 1-year incidence of STB among first-year students, a broad range of prospective predictors of STB incidence, and evaluated the prediction accuracy of a baseline multivariate risk prediction model to identify students at highest risk for STB onset over the subsequent 12 months. METHODS: Students (n = 3238) from 13 universities in Mexico completed an online survey developed for the World Mental Health International College Student Surveys in their first year and again 12 months after. We ran generalized linear models and receiver operator curves. RESULTS: The 1-year incidence of suicidal ideation, plan and attempt was 8.53%, 3.75%, and 1.16%, respectively. Predictors in final models were female sex (ideation only), minority sexual orientation (ideation only), depression, eating disorders, ADHD (ideation and plan), ongoing arguments or breakup with a romantic partner (ideation only), emotional abuse (ideation only), parental death (ideation, plan), not Catholic/Christian (ideation, plan), not having someone to rely on, psychotic experiences (plan only), and insufficient sleep (attempt only). Prediction accuracy for ideation, plan and attempt was area under the curve = 0.76, 0.81 and 0.78, respectively. Targeting the top 10% of students at highest risk could reduce STB in the subsequent year up to 36%. CONCLUSIONS: By assessing these risk/protective factors in incoming students we identified students at greatest risk for developing STB to whom suicide prevention strategies could be targeted.

RESUMO

PURPOSE: Mental health disparities have been documented among sexual minority college students, but there is a dearth of evidence from developing countries. The aim is to estimate the prevalence of 12-month mental and substance use disorders across a range of sexual identities among first-year college students in Mexican universities, and test whether there is an association between sexual identity and disorders and whether the association is moderated by gender. METHOD: The University Project for Healthy Students, a web-based survey conducted as part of the World Health Organization's World Mental Health International College Student initiative, recruited 7874 students from nine Mexican universities in 2016 and 2017. Logistic regressions estimated the association of sexual identity with 12-month major depressive episode, generalized anxiety disorder, panic disorder, alcohol abuse/dependence, and drug abuse/dependence, with interaction terms for gender. RESULTS: Compared to heterosexual students reporting no same-sex attraction (SSA), heterosexual students with SSA (AORs range 1.77-3.67) and lesbian/gay and bisexual students (AORs range 2.22-5.32) were at a higher risk for several disorders. Asexual students were at higher risk for drug abuse/dependence (AOR = 3.64). Students unsure of their sexual identity were at a higher risk for major depressive episode, panic disorder, and drug abuse/dependence (AORs range 2.25-3.82). Gender differences varied across sexual identity and disorder. CONCLUSION: These findings are the first empirical report of sexual minority psychiatric disparities among a college student population from a developing nation and underscore the importance of clinical interventions that address mental health needs among sexual minority college students.

RESUMO

BACKGROUND: Sexual minority college students are at a higher risk for suicidal thoughts and self-injurious behaviors compared to heterosexual students. Minority stress theory proposes sexual minority individuals experience higher stress due to stigma. Using a sample of Mexican college students, this study tested perceived life stress as a mediator of suicide and self-injury outcomes across various sexual orientation groups. METHODS: The sample of college students (N=7882) was recruited from nine Mexican universities as part of the WHO World Mental Health International College Student (WMH-ICS) initiative. Participants completed an online survey including demographic questions, measure of perceived life stress, suicide outcomes, and non-suicidal self-injury (NSSI) in the past 12 months. RESULTS: Logistic regression analyses revealed identifying as a sexual minority significantly predicted a higher likelihood of suicide ideation (ORs 2.05-3.00), suicide attempts (ORs 2.48-8.73), and NSSI (ORs 2.92-4.18) compared to heterosexual students reporting no same-gender attraction. Significant indirect effects from mediation path analyses showed perceived life stress mediated the relationship between a sexual minority identity and suicide ideation (range of proportion mediated 10.48-31.48%), attempts (10.48-31.48%), and NSSI (7.69-20.09%) across each group except among asexual students. LIMITATIONS: The cross-sectional nature of the survey design precludes drawing causal inferences. CONCLUSION: Findings from this study contribute to minority stress theory by elucidating the role of perceived life stress as a mediator of suicide ideation and attempts and NSSI among sexual minority college students. Clinical interventions may benefit in focusing on experiences of stress across various life areas when supporting sexual minority college students.
