Childhood exposure to violence is associated with risk for mental disorders and adult’s weight status: a community-based study in Tunisia

BACKGROUND: We sought to investigate the relationship between social violence and adult overweight/obesity and the role of common mental disorders (CMD) in mediating this relationship. METHODS: A cross-sectional study was conducted from January to June 2016 in Tunisia. Participants were selected from randomly selected Primary Health Care Centers. The Arabic version of the Adverse Childhood Experiences-International Questionnaire (ACE-IQ) was used. RESULTS: A total of 2120 participants were included. Women exposed to social ACEs had higher rates of overweight/obesity than men (13.5 versus 9.5%; P = 0.004). For women, statistically significant partial mediation effects of CMD were observed for exposure to community violence (% mediated = 17.7%). For men, partial mediation was found for the exposure to peer violence (% mediated = 12.5%). CONCLUSION: Our results provide evidence of the independent increase of overweight/obesity after exposure to social ACEs. Efforts to uncover and address underlying trauma in health care settings may increase the effectiveness of obesity interventions.
