Effects of the Dietary Program, Physical Activity, and Mental Health Promotion Among Overweight in High School Students
Main Article Content
Abstract
The quasi-experimental research aimed to assess the efficacy of a comprehensive program involving dietary modifications, physical activity, and mental health promotion among overweight high school students. The experimental group consisted of 40 overweight students from a high school in Ubon Ratchathani province, which had the highest overweight rate (body mass index ≥ 23 kg/m2) in the province, while the control group comprised 40 overweight students from a high school in Sisaket Province, which also had a high overweight rate. The study spanned 12 weeks from July to September 2023. Data were collected before and after the intervention, including body mass index (BMI), body fat percentage, muscle mass percentage, and responses to a structured questionnaire on demographic characteristics, knowledge about diet and exercise, eating behavior, physical activity, and depression (9Q). Statistical analyses included frequency, percentage, mean, standard deviation, and independent sample t-tests. Prior to the intervention, there were no significant differences between the experimental and control groups. However, after the intervention, the experimental group showed lower BMI, body fat percentage, and depression levels compared to the control group, with statistical significance at p-value < 0.05. Additionally, the experimental group exhibited higher muscle mass percentage, knowledge about diet and exercise, and healthier eating and physical activity behaviors compared to the control group, also with statistical significance at p-value < 0.05. Therefore, the dietary program, physical activity, and mental health promotion among overweight high school students showed promising results and could be applied in organizing similar activities for overweight groups in other areas.
