We examined the associations of type 2 diabetes, obesity, physical activity, diet quality, and socioeconomic status among adults participating in the 1999–2000 National Health and Nutrition Examination Survey. The analytical sample included 3292 people (460 with type 2 diabetes; 1096 Mexican Americans, 781 blacks, 1734 whites, 381 other/mixed ethnicities) between ages 20–84y. Waist circumference (WC) and Healthy Eating Index (HEI) were used as proxies of central adiposity and dietary quality, respectively. The sample (mean age 45y) was 51% female; 24% had not graduated from high school. About 46% had a high WC (>88 cm in women or >102 cm in men), and 40% were sedentary at leisure‐time (moderate/vigorous activities <10 minutes/30d). HEI and leisure‐time physical activity were not directly related to having diabetes, but they were negatively related to WC after adjusting for confounders (p<0.05). WC modified the association of ethnicity and diabetes. At low WC, only Mexican Americans (vs. whites) were significantly more likely to have diabetes. If they had high WC, however, whites were about 4 times, Mexican Americans were about 5 times, and blacks were about 9 times more likely to have diabetes than whites with low WC. Central adiposity seems to modify the relationship between ethnicity/race and type 2 diabetes. Funding: USDA‐FNS; CT Latino NIH EXPORT Health Disparities Center; ARS 58‐1950‐9‐00.
