Is Crime Associated with Obesity and High Blood Pressure? Repeated Cross-Sectional Evidence from a Peruvian Study

Violence is an emerging social determinant of health in Latin America; however, empirical evidence from Peru remains limited. This study examined the association between crime rates and the prevalence of obesity and high blood pressure in Peru from 2019 to 2023. Using a repeated cross-sectional design with department–year aggregates, we analyzed nationally representative data from the Demographic and Family Health Survey, adjusting for sociodemographic, mental health, and geographic factors. Regional statistics on crime were incorporated into the analysis. The findings revealed a significant association between higher levels of crime and increased prevalence of self-reported high blood pressure and obesity. The association with obesity was particularly pronounced in border regions such as Tumbes, Madre de Dios, and Callao, where criminal activity is more prevalent. The findings indicate that prolonged exposure to violence may negatively impact biological stress responses, limit physical activity, and encourage the emergence of detrimental behaviors, consequently increasing the cardiometabolic risk burden in affected populations.
