Abstract

Background: We examined the fast food consumption-suicide attempt relationship among 105,061 adolescents aged 12-15 years from 32 countries. Methods: This study was based on cross-sectional data from the Global School-based Student Health Survey (GSHS), and included 4 low-income, 13 lower middle-income, 9 upper middle-income, and 6 high-income countries. Data on past 7-day fast food consumption and 12-month suicide attempts were collected. The association between fast food consumption and suicide attempts was investigated with multivariable logistic regression and meta-analysis while adjusting for sex, age, food insecurity (proxy of socioeconomic status), alcohol consumption, smoking, physical activity, obesity, carbonated soft drink consumption, and fruit and vegetable consumption. Results: Overall, the prevalence of fast food consumption was high (53.5%) and the proportion of suicide attempts was higher among consumers of fast food compared to non-consumers (11.8% vs. 8.3%). Of the 32 countries included in the study, a positive association between fast food consumption and suicide attempts was found in 26 countries although this was not statistically significant in all countries. The pooled OR (95% CI) based on a meta-analysis was 1.31 (1.17-1.46). Limitations: Since this was a cross-sectional study, it is not possible to draw any conclusions about causality or temporality in the associations assessed. Conclusions: Fast food consumption is positively associated with suicide attempts in adolescents. Further research of longitudinal design is needed to confirm/refute our findings and explore the potential underlying mechanisms.
