尽管美国人口日益多样化，但平均体重指数（BMI）仍在上升。我们通过检查不同群体的BMI趋势来扩展先前的研究，这些群体包括白人，黑人，中国人，菲律宾人，亚洲印第安人，墨西哥人，波多黎各人和古巴人，他们是美国出生的，最近的移民或长期移民。我们汇总了1989年至2011年全国健康访谈调查（N= 989，273）的横截面数据，并使用线性回归模型来研究美国成年人BMI的趋势。在美国出生的波多黎各人和墨西哥人中，BMI的年增长率最高，而在外国出生的中国人中，BMI的年增长率最低。在2011年出生的美国人中，中国成年人的平均BMI低于超重阈值，而黑人，墨西哥人和波多黎各人的平均BMI在肥胖范围内。在大多数种族/族裔群体中，外国出生的成年人的平均BMI低于美国出生的成年人，出生差异通常会随着时间的推移而扩大。BMI在日历期间而不是出生队列中增加。我们的研究结果表明，日历期间的干预措施可能是特别有用的逆转上升的BMI在美国然而，干预措施必须针对不同的种族/民族和出生群体，以减少体重的差异。
The average body mass index (BMI) is rising even as the U.S. population grows increasingly diverse. We extend prior research by examining BMI trends in diverse groups including whites, blacks, Chinese, Filipinos, Asian Indians, Mexicans, Puerto Ricans, and Cubans who are U.S. born, recent immigrants, or long-term immigrants. We pool cross-sectional data from the 1989 to 2011 waves of the National Health Interview Survey (N=989,273) and use linear regression models to examine trends in BMI among U.S. adults. Annual increases in BMI are greatest among U.S. born Puerto Ricans and Mexicans and slowest among foreign born Chinese. Among the U.S. born in 2011, Chinese adults have an average BMI below the threshold for overweight, whereas blacks, Mexicans, and Puerto Ricans have average BMIs in the obese range. Foreign born adults average lower BMIs than U.S. born adults in most race/ethnic groups, and nativity disparities generally widen over time. BMI increases across calendar periods rather than birth cohorts. Our results suggest that calendar period interventions may be particularly useful in reversing rising BMIs in the U.S. However, interventions must be tailored to different race/ethnic and nativity groups in order to reduce disparities in body mass.
