Healthy Weight Management Project for Overweight and Obesity Children

Healthy Weight Management Project for Overweight and Obesity Children in Ningbo City

Childhood obesity is a significant public health concern worldwide. In China, childhood obesity has dramatically increased as the economy has grown quickly over the past decades. Nonalcoholic fatty liver disease (NAFLD) is tightly associated with obesity, in China, the prevalence of NAFLD in obesity children is 40.0%，the main interventions for NAFLD are lifestyle interventions. Effective strategies to helping students lose weight and alleviate NAFLD through lifestyle interventions may help promote the physical and mental health of obese students.

This study aimed (1)to assess the effectiveness of the intervention compared with the usual practice in treating childhood overweight and obesity; (2) to determine the sustainability of the treatment in preventing overweight and obesity; (3) to help alleviate or reverse NAFLD in obesity children.

Children with overweight and obesity in six primary schools in Ningbo City, Zhejiang Province will be seleted and randomly divided into two groups: the treatment group and the usual practice group. The participants of the study were students in the third grade of primary school, and the treatment will last for one academic year. This treatment activity on lifestyle interventions will target the dietary and exercise factors of childhood obesity.
