Body weight and length of residence in the US among Chinese Americans

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 datafrom 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.
