这项研究调查了1976至2008年间美国30个移民群体的肥胖和超重患病率和身体质量指数(BMI)的趋势，这些群体按种族/民族和移民时间分层，并在详细的教育、职业和收入/贫困群体中进行分层。利用1976-2008年国民健康访谈调查，基于自我报告的身高和体重，使用差异指数、逻辑和线性回归分析肥胖、超重和BMI的差异。≥18岁的美国人口的肥胖率从1976年的8.7%增加到2008年的27.4%，增加了两倍。超重率从1976年的36.9%上升到2008年的62.0%。1991-2008年间，在美国出生的成年人的肥胖率从13.9%上升到28.7%，而移民的肥胖率从9.5%上升到20.7%。虽然移民在各个种族和时间段的肥胖和超重患病率和BMI低于美国出生的移民，但移民肥胖和超重的风险随着居住时间的增加而增加。在2003-2008年间，肥胖率从最近的中国移民的2.3%到美国印第安人、美国出生的黑人、墨西哥人和波多黎各人以及墨西哥和波多黎各长期移民的31%到39%不等。1976年至2008年间，受过大学教育或从事销售工作的人的肥胖率增加了三倍多。虽然在每个时期观察到低教育、低收入和低职业水平的患病率较高，但肥胖和超重的社会经济梯度随着时间的推移而下降，因为在较高的社会经济群体中患病率上升得更快。持续的移民和社会经济差异可能会对美国未来的肥胖趋势产生重大影响。
This study examined trends in US obesity and overweight prevalence and body mass index (BMI) among 30 immigrant groups, stratified by race/ethnicity and length of immigration, and among detailed education, occupation, and income/poverty groups from 1976 to 2008. Using 1976–2008 National Health Interview Surveys, differentials in obesity, overweight, and BMI, based on self-reported height and weight, were analyzed by using disparity indices, logistic, and linear regression. The obesity prevalence for the US population aged ≥18 tripled from 8.7% in 1976 to 27.4% in 2008. Overweight prevalence increased from 36.9% in 1976 to 62.0% in 2008. During 1991–2008, obesity prevalence for US-born adults increased from 13.9 to 28.7%, while prevalence for immigrants increased from 9.5 to 20.7%. While immigrants in each ethnic group and time period had lower obesity and overweight prevalence and BMI than the US-born, immigrants’ risk of obesity and overweight increased with increasing duration of residence. In 2003–2008, obesity prevalence ranged from 2.3% for recent Chinese immigrants to 31–39% for American Indians, US-born blacks, Mexicans, and Puerto Ricans, and long-term Mexican and Puerto Rican immigrants. Between 1976 and 2008, the obesity prevalence more than quadrupled for those with a college education or sales occupation. Although higher prevalence was observed for lower education, income, and occupation levels in each period, socioeconomic gradients in obesity and overweight decreased over time because of more rapid increases in prevalence among higher socioeconomic groups. Continued immigrant and socioeconomic disparities in prevalence will likely have substantial impacts on future obesity trends in the US.
