摘要: Background Although obesity is frequently associated with poverty, recent increases in may not occur disproportionately among the poor. Furthermore, relationship between income and weight status be changing time. Methods We use nationally representative data from National Health Nutrition Examination Surveys (1971-2002) to examine (1) differentials body mass index (calculated as kilograms divided by square of height meters) (2) change over time prevalence (body index, ≥30) at different levels income. Results Over course 3 decades, has increased all Moreover, it typically poor who have experienced largest gains. For example, black women, absolute increase 27.0% (1.05% per year) for those middle incomes, but only 14.5% (0.54% Among men, 21.1% (0.77% highest level income, 4.5% (0.06% near 5.4% (0.50% race-sex groups show on patterns substantial variation consistency within white women consistently a strong inverse gradient, while positive gradient emerges later waves Mexican American men. Conclusion The persistence emergence gradients suggests that disparities are partially attributable poverty efforts aimed reducing need consider much broader array contributing factors.
