Weight Status Change in Chinese American Children over a Ten-Year Period: Retrospective Study of a Primary Care Pediatric Population

Weight change from childhood to adolescence has been understudied in Asian Americans. Known studies lack disaggregation by Asian subgroups. This retrospective study assessed the weight status change in 1500 Chinese American children aged 5-11 years from an urban primary care health center between 2007 and 2017. Weight status was categorized using the 2000 CDC growth charts into "underweight/normal weight" and "overweight/obese". The overweight/obesity prevalence in 2007 and 2017 were determined. McNemar's test and logistic regression were performed. The prevalence of overweight/obesity decreased from 29.9% in 2007 to 18.6% in 2017. Children who were overweight/obese at 5-11 years had 10.3 increased odds of staying overweight/obese over time (95% CI = 7.6-14.0, p < 0.001) compared to their underweight/normal weight counterparts. Of the children who were overweight/obese in 2007, 45.7% remained overweight/obese ten years later. Childhood overweight/obesity strongly predicts adult overweight/obesity in Chinese Americans. Targeted education and intervention are warranted to prevent adult obesity.
