Insights
A stage-based lifestyle intervention improved weight management in obese children by increasing physical activity. This approach showed effectiveness in controlling obesity indicators compared to standard care.
Area of Science:
- Pediatric Endocrinology
- Behavioral Medicine
- Public Health Nutrition
Background:
- Childhood obesity management requires interventions targeting dietary intake and physical activity.
- Behavioral modifications are crucial for effective obesity treatment in pediatric populations.
Purpose of the Study:
- To assess the effectiveness of a stage-based lifestyle modification intervention for obese children.
- To evaluate changes in body composition, physical activity, and dietary intake following the intervention.
Main Methods:
- A randomized controlled trial involving 50 obese children aged 7-11 years.
- Intervention group received stage-based lifestyle modifications; control group received standard treatment.
- Data collection occurred at baseline, monthly follow-ups, and six months post-intervention.
Main Results:
- The intervention group showed a significantly lower increase in weight and waist circumference compared to the control group.
- Body Mass Index (BMI)-for-age z scores significantly decreased in the intervention group.
- Physical activity levels significantly increased in the intervention group, unlike the control group.
Conclusions:
- A stage-based intervention focusing on dietary and physical activity behaviors can be effective for managing childhood obesity.
- This approach demonstrates potential for improving key obesity indicators in children.
Background:
Interventions that encompass behavioural modifications of dietary intake and physical activity are essential for the management of obesity in children. This study assessed the effectiveness of a stage-based lifestyle modification intervention for obese children.
Methods:
A total of 50 obese children (7-11 years old) were randomized to the intervention group (IG, n = 25) or the control group (CG, n = 25). Data were collected at baseline, at follow-up (every month) and at six months after the end of the intervention. IG received stage-based lifestyle modification intervention based on the Nutrition Practice Guideline for the Management of Childhood Obesity, while CG received standard treatment. Changes in body composition, physical activity and dietary intake were examined in both the intervention and control groups.
Results:
Both groups had significant increases in weight (IG: 1.5 ± 0.5 kg; CG: 3.9 ± 0.6 kg) (p < 0.01) and waist circumference (IG: 0.1 ± 0.5 cm; CG: 2.2 ± 0.7 cm) (p < 0.05), but the increases were significantly higher in CG than IG. Body Mass Index (BMI)-for-age z scores decreased significantly in IG (- 0.2 ± 0.0, p < 0.01) but not in CG. The physical activity of the IG significantly increased (0.44 ± 0.13) compared with that of CG (- 0.28 ± 0.18), and the difference in mean change between groups was statistically significant (p < 0.05). Dietary intake was not significantly different between the two groups. However, calorie and carbohydrate intake decreased significantly in both groups.
Conclusions:
A stage-based intervention that modified dietary and physical activity behaviour may be effective in weight management for obese children.
