This cross-sectional study examined the relationships between length of residence in the United States (U.S.) and dietary and physical activity acculturation, and the relationships between dietary and physical activity acculturation and weight status in 55 Chinese college students. Length of residence in the U.S. was positively associated with larger portion size, greater amount of physical activity, and change in BMI in male participants. Adoption of a Western diet was associated with weight gain. Portion size change was positively associated with BMI change. Lunch size change was positively correlated with BMI change in males while negatively correlated with BMI change in females. And dinner size change was positively correlated with BMI change in males. This study suggests that dietary acculturation is positively associated with weight gain in Chinese college students. Future interventions focusing on multi-dimensional aspects of dietary behavior change--especially portion size and meal size changes--while emphasizing the importance of changes in physical activity are needed. Such interventions may help maintain healthy weight status and prevent individuals in this population from becoming overweight or obese.
