Use of Food to Cope with Culturally-Relevant Stressful Life Events is Associated with Body Mass Index in African American Women.

Abstract

BACKGROUND\nAlthough stress is an established contributor to obesity (in general population studies), mechanisms to explain this association in African American women that incorporate culturally relevant frameworks have received little attention.\n\n\nOBJECTIVE\nTo investigate how stress is associated with Body Mass Index (BMI) in this population, we examined multivariate models of BMI predicted by race-related, gender-related, and generic stressful life events and by use of food to cope with stress. We hypothesized that the three types of stressful life events would be indirectly associated with BMI through using food to cope with stress.\n\n\nMETHODS\nPsychometrically robust measures were included in surveys administered to a socioeconomically-diverse sample of 189 African American women aged 21-78. Hypotheses were tested using structural equation modeling. We examined race-related, gender-related, and generic stressful life events as latent constructs indicated by exposure to and appraisal of potential stressors predicting a mediator, using food to cope, which predicted BMI; this model also included direct paths from the three latent stressful life event constructs to BMI.\n\n\nRESULTS\nAlmost every participant reported using food in some way to cope with stress; 33% and 42% met established criteria for overweight and obesity, respectively. The race-related stressful life event construct was the only latent construct predicting using food to cope with stress and using food to cope with stress predicted BMI. A significance test of indirect effects demonstrated that the race-related stressful life event construct was indirectly associated with BMI through the mediator, using food to cope.\n\n\nDISCUSSION\nCulturally-relevant stress exposures and stress-related eating are important areas of foci for tackling overweight and obesity and related health inequities in African American women. Findings highlight the importance of developing more complex models to understand the stress-related factors that elevate risk for overweight and obesity in this population.
