So, what is responsible for this association? There are at least two possibilities: obesity influences socioeconomic status or socioeconomic status influences obesity. But there is strong evidence supporting the latter as highlighted by the causal pathway between being poor and being at higher risk for obesity.
Recent studies reinforce this notion in suggesting that the direct causes of obesity have their roots in systemic social and economic factors that are not easily overcome by "eating less and not sitting around." Such socioeconomic factors that influence obesity have been documented in three areas: education, health care, and employment. These three elements inevitably tie racial elements to health outcomes such as obesity in the U.S.
For example, low income and low education is found to be strongly associated with both obesity and obesity comorbidities in etiological studies. Researchers found that weight gain over time in developed countries was associated with lower education levels and "blue-collar" occupations. Moreover, it is also found that the prevalence of obesity tends to shift toward lower socioeconomic groups as the country 's gross national product rises (Drewnowski et al., 2005). African-Americans in poor, urban environments reinforce the validity of these statistics. A 34-year study found that weight gain among African-Americans in the study was associated with low overall SES (socioeconomic status) calculated over three decades.
