Food insecurity and suicidal behaviours among Bangladeshi university students: a multi-institutional cross-sectional study

Abstract

Abstract Objective: Suicidal behaviours among students pose a significant public health concern, with mental health problems being well-established risk factors. However, the association between food insecurity (FIS) and suicidal behaviours remains understudied, particularly in Bangladesh. This study aimed to investigate the relationship between FIS and suicidal behaviours among Bangladeshi university students. Design: A cross-sectional survey using convenience sampling was conducted between August 2022 and September 2022. Information related to socio-demographics, mental health problems, FIS and related events and suicidal behaviours were collected. Chi-squared tests and multivariable logistic regression models, both unadjusted and adjusted, were employed to examine the relationship between FIS and suicidal behaviour. Setting: Six public universities in Bangladesh. Participants: This study included 1480 students from diverse academic disciplines. Results: A substantial proportion of respondents experienced FIS, with 75·5 % reporting low or very low food security. Students experiencing FIS had a significantly higher prevalence of suicidal ideation, plans and attempts compared with food-secure students (18·6 % v. 2·8 %, 8·7 % v. 0·8 % and 5·4 % v. 0·3 %, respectively; all P < 0·001). In addition, students who have personal debt and participate in food assistance programmes had a higher risk of suicidal behaviours. Conclusions: This study highlights the association between FIS and suicidal behaviours among university students. Targeted mental health screening, evaluation and interventions within universities may be crucial for addressing the needs of high-risk students facing FIS.
