Objective
This study aimed to examine the explanatory role of health behaviors, socioeconomic position (SEP), and psychosocial stressors on racial/ethnic obesity disparities in a multiethnic and multiracial sample of adults.
Methods
Using data from the Chicago Community Adult Health Study (2001â2003), OaxacaâBlinder decomposition analysis was conducted to quantify the extent to which health behaviors (fruit and vegetable consumption and physical activity), SEP, and cumulative stressors (e.g., perceived discrimination, financial strain) each explained differences in obesity prevalence in Black, USâborn Hispanic, and nonâUSâborn Hispanic compared with nonâHispanic White participants.
Results
SEP and health behaviors did not explain obesity differences between racial/ethnic minorities and White individuals. Having high levels of stress in four or more domains explained 4.46% of the differences between Black and White individuals, whereas having high levels of stress in three domains significantly explained 14.13% of differences between USâborn Hispanic and White. Together, the predictors explained less than 20% of differences between any racial/ethnic minority group and White individuals.
Conclusions
Exposure to stressors may play a role in obesity disparities, particularly among Black and USâborn Hispanic individuals. Other obesityârelated risk factors need to be examined to understand the underlying mechanisms explaining obesity disparities.
