Childhood Obesity
Conditions
Brief summary
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. Effective strategies to reduce childhood obesity prevalence may help to prevent related chronic diseases in the whole population in the long term. This study aimed (1)to assess the effectiveness of the intervention compared with the usual practice in preventing childhood overweight and obesity; (2) to determine the sustainability of the intervention in preventing overweight and obesity; and (3) to evaluate the process and health economics of the intervention. The project will be carried out in six primary schools in Ningbo City, Zhejiang Province , those schools are randomly divided into two groups: the intervention group and the usual practice group. The participants of the study were students in the third grade of primary school, and the intervention will last for one academic year. This intervention programme will target the influencing factors of childhood obesity at both individual (student-focused activities) and environmental levels (a supportive family and school environment), with the intent to influence the knowledge, attitude and behaviours of school children.
