简要总结
Considering that children with intellectual disability (ID) might be more vulnerable to obesity than their counterparts in the general population. This study aimed to develop and evaluate the effectiveness of an adapted physical activity (APA) program in reducing weight among adolescents with ID. The hypothesis of the study was the APA program would be able to decrease obesity among adolescents with ID.
详细描述
Background: Children with intellectual disability (ID) might be more vulnerable to obesity than their counterparts in the general population. This study aimed to evaluate the effectiveness of an adapted physical activity (APA) program in reducing weight among adolescents with ID.
Methods: A 9-month randomized controlled trial of a school-based APA program was conducted in adolescents with ID and overweight/obesity in Hong Kong. The intervention group received the APA program which consisted of endurance and strength-building exercises at a frequency of two sessions per week, while the control group received routine PE classes as usual. Data on obesity-related variables were collected before the intervention, at the midpoint of the intervention and after the intervention. Linear mixed-effect models were used to examine the intervention effects.

结局指标
主要结局
BMI Change
时间窗: Change from baseline at 4 months and 9 months
The primary outcome variable was change in BMI (weight (kg) / height2 (m)) that was further calculated from the height and weight measured at school in the morning time. Height was measured to the nearest 0.1 cm using a stadiometer and weight was measured to the nearest 0.1 kg on a TANITA digital scale (TBF-410) with the subject wearing lightweight clothing and no shoes.
