First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests a digital health platform delivered through WeChat to prevent obesity in 1,400 school children in grades 2 and 3. The program includes health education, growth monitoring, behavior tracking, and home-school partnerships. Researchers will compare children using the platform with those receiving usual care to see if it improves BMI and healthy behaviors.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Schools will be selected based on the consent of primary leadership, demonstrated cooperation, and availability of necessary personnel (e.g., school health professionals). Classes will be limited to grades 2 and 3, with teachers showing strong willingness to collaborate. Both parental informed consent and child assent are required for participation. Exclusion Criteria: * Schools will be excluded if they cater to special populations (e.g., schools for children with disabilities), are involved in other obesity-related interventions within the specified timeframe, or plan to close or relocate within two years. Children will be excluded if they have histories of major organ diseases (e.g., cardiac, pulmonary, hepatic, or renal conditions), special diets (e.g., vegetarian), pathological eating disorders, physical limitations affecting activity, or obesity due to endocrine disorders or medication side effects.
