While racial/ethnic minority communities are often impoverished, social standing alone does not explain the disparity between communities. A 2009 study in the Journal of Epidemiology and Community Health found that racial/ethnic minorities have a higher risk of being obese within each observed socioeconomic group.[18] This finding suggests that race may be a key indicator in determining disparities of obesity risk. The study also implies that structural racism may be causing certain racial/ethnic groups to experience a disproportionate risk, as class alone does not determine the likelihood of a person being obese.
