BACKGROUND
It has been shown that as immigrants' length of residence increases, so does their weight. However, little is known about factors associated with weight status among Chinese Americans, one of the fastest growing immigrant populations in the US.
METHODS
Baseline data from a National Cancer Institute-funded longitudinal study involving a multi-stage probability sample of Chinese Americans residing in two communities in New York City were collected.
RESULTS
Chinese Americans had a low BMI (mean = 22.81) and a lower proportion of obese individuals compared with other ethnic groups in the US reported in the literature. While the prevalence of being overweight (21%) and obese (2%) was low, length of residence was positively associated with weight status (P < 0.005).
CONCLUSIONS
Innovative strategies to help Chinese Americans maintain healthy weight status and to prevent them from becoming overweight and obese are needed.
背景
研究表明，随着移民在美居住时间的延长，他们的体重也会增加。然而，鲜少有研究关注在美国迅速增长的移民群体之一——美籍华人的体重状况与哪些因素有关。
方法
本研究的数据来自国家癌症研究所资助的一项纵向研究，研究对象为居住在纽约市两个社区的美籍华人，采用多阶段概率抽样。
结果
与文献报道的美国其他族裔相比，美籍华人的 BMI 较低（均值=22.81），肥胖人群的比例也较低。尽管超重（21%）和肥胖（2%）的比例较低，但在美居住时间与体重状况呈正相关（P<0.005）。
结论
需要采取创新性策略，帮助美籍华人保持健康的体重状况，防止他们超重和肥胖。
