Abstract
OBJECTIVE: To describe racial and gender differences in insulin resistance-associated parameters due to sugar-sweetened beverage (SSB) intake and physical activity (PA) levels in the adolescent population. METHODS: Data from individuals aged 12 to 19 years from the National Health and Nutrition Examination Survey during the years 1999-2004 were analyzed. SSB intake and PA levels were evaluated in Non-Hispanic whites, Non-Hispanic blacks, and Mexican Americans. Outcome measures included measurements of insulin sensitivity, lipids, blood pressure, waist circumference, and body mass index. RESULTS: Multivariate linear regression analyses showed that anthropometric measurements, metabolic parameters, and indices of insulin resistance differed among the racial groups. Moreover, within each of these racial groups, they differed between the sexes. CONCLUSIONS: The differing relationships between insulin resistance-associated parameters and SSB intake and PA levels among racial groups and between the sexes illustrate the importance of race and gender in the investigation of diseases such as obesity and metabolic syndrome.
