WeChat weight program shows promise for kids with autism
NCT ID NCT07514910
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a 16-week lifestyle program delivered through WeChat could help children with autism (ages 8-12) manage their weight. 276 families were split into three groups: usual care, the WeChat program alone, or the program plus weekly group coaching. The main goal was to see if the program could reduce BMI z-scores, a measure of weight relative to age and sex.
