title: Association between obesity and suicide in woman, but not in man: a population-based study of young adults.
abstract: The relationship between obesity and suicide risk is still unclear with controversial research results. The aim of this study is to investigate the relationship between obesity and suicide risk for men and women in a population-based study of young adults. This is a cross-sectional population-based study that identified young adults between 18 and 35 years of age. Suicide risk was investigated through the structured clinical interview Mini. Weight and height were assessed, and participants were classified as normal-weight body mass index (BMI < 30) or obese (BMI > 30). The prevalence of obesity was of 19.9% of the total sample (n = 1953). Obesity was more prevalent among women and participants between 27 and 35 years of age. Suicide risk was present in 13.0% of the sample and more prevalent among women. In our study we found an association between obesity and suicide risk for women, but not for men. Obesity was associated with a higher prevalence of suicide risk in women. Given the strength of the relationship between BMI and suicide, identifying the mechanisms associated with obesity, especially for women, can lead to new insights into the prevention of suicide risk.
