Influence of the Growth and Development Check (GDC) on Overweight/Obesity of Children under-5 Years in China: A Propensity Score Analysis.

To improve health and reduce the rapidly increasing prevalence of overweight and obesity in children, the Chinese government has formulated childcare standards, with the Growth and Development Check (GDC) as the main content. However, few studies have evaluated the impact of the GDC on lowering the risk of childhood overweight and obesity. Using the 2014 China Family Dynamics Survey and propensity score matching (PSM), this article examined the impact of the GDC on overweight/obesity in children aged 5 years and younger. The results revealed that the mean Body Mass Index (BMI) was 17.80 kg/m2, and the prevalence of overweight/obesity was 24.62% in children. Children whose parents were aware of the GDC had a lower BMI and a lower risk of overweight/obesity than those whose parents were not aware of it. Children who engaged in the GDC in the last 12 months had a lower BMI and a lower chance of overweight/obesity than those not engaged.
