Adolescent obesity is a major public health problem in the United States. The aim of this research is to explore the association between demographic risk factors, behavioral risk factors, acculturation and environmental risk factors and adolescent obesity in the CHIS 2007 data. A bivariate analysis for frequency distribution was used to evaluate the data, and multiple logistic regression models were used to assess the association of obesity and other risk factors through the odds ratio. Logistic regression for demographic data showed that Africans (OR 2.894, CI 2.019, 4.148), Latinos (OR 2.254, CI 1.805, 2.814) and other races (OR 1.357 CI 1.060, 1.738) were significantly associated with obesity (BMI ≥ 25) when compared with whites. Boys were significantly associated with Obesity (OR 1.398, CI 1.183, 1.653) when compared to girls. Fast food consumption frequency, soda intake or physical activity frequencies were not significantly associated with Obesity. Adolescents with Medicaid health insurance were significantly associated with Obesity (OR 1.623 CI 1.293, 2.037) when compared to reference group of adolescents with employment based insurance. Other insurance types, private, healthy families, uninsured and other public were not significantly associated with obesity. After adjusting for park near house, years lived in US, adult presence at home, fast food and soda consumption. A significant association between Africans and obesity still persisted (OR 3.067, CI 2.151, 4.374) when compared to whites. Same significant associations also persisted for Latinos (OR 2.274, CI 1.837, 2.814) and other races (OR 1.375, CI 1.079, 1.753). Boys remained more likely to be obese when compare with girls 1.398(1.183-1.653) and adolescents with Medicaid health insurance were still more likely to be obese when compared with adolescents with employment based insurance (OR 1.649, CI 1.320, 2.059).
