Environmental and lifestyle changes have been attributed to the recent increase in obesity prevalence in the U.S. as if the US population is homogeneous. We aimed to examine changes in predictors of obesity over the past decade among the U.S. subgroups by gender and income. We examined adults aged 20+ y in NHANES 1988–94 and 1999–2002. Logistic regression was conducted to determine the predictors of obesity in the subgroups, using SAS Callable SUDAAN. Changes in the prevalence over the past decade ranged from −0.2 % (Mexican‐American low‐income men; 23.6 to 23.4%) to 14.2% (Mexican‐American high‐income women; 25.1 to 39.3%) with minimally accounted for by aging U.S. population. These changes were associated with smoking, alcohol intake, leisure‐time activity, age at first menarche, number of live births, perception and behavior toward participant's weight status, number of eating episode, and fat intake. In developing nutrition intervention programs to reduce obesity prevalence, one must consider these predictors specific for certain subgroups in the U.S.
