Eating in the absence of hunger (EAH) in response to negative affect may explain the association between exposure to early life adversity (ELA) during the preschool period and the development of obesity in adolescence. We examined the association between exposure to early life adversity—specifically cumulative sociodemographic risk at age 35 months—and adolescent obesity risk. Participants included 218 adolescents, drawn from a sample of rural households that experienced poverty. Data were collected through in-person home visits and web surveys; only individuals who completed in-person home visits were included in the analysis. Adolescents completed questionnaires and had their waist circumference measured during the home visit. Results showed that there was no direct association between exposure to ELA and adolescent waist circumference. Cumulative sociodemographic risk, however, significantly predicted EAH negative affect (p=0.05) and EAH negative affect significantly predicted waist circumference (p=0.003). Given no direct relation between adversity and obesity risk, we conclude that EAH negative affect did not mediate this association. These findings suggest that early life adversity may contribute to emotional eating behaviors in adolescence, which could have long term implications for obesity risk, but further research is needed on the mechanisms linking early life adversity and adolescent obesity.Lori Anne Francis, Thesis SupervisorKari Christine Kugler, Thesis Honors Advisoropen_access2025-04-06T00:27:24Zhttps://honors.libraries.psu.edu/catalog/9604srt5438
