Insights
This study found that the Kids4Fit multidisciplinary program effectively reduced waist circumference in obese children from deprived areas. However, it did not significantly impact BMI-z, lifestyle, or quality of life.
Area of Science:
- Pediatric Obesity Research
- Public Health Interventions
- Behavioral Medicine
Background:
- General Practitioners (GPs) can refer obese children in deprived areas to multidisciplinary weight loss programs.
- The effectiveness of these targeted local initiatives for this specific demographic remains largely unknown.
Purpose of the Study:
- To evaluate the effectiveness of the Kids4Fit intervention in deprived areas on children's weight status.
- Assessing the impact on body mass index (BMI-z) and waist circumference.
Main Methods:
- A cohort study with a waiting list control period was conducted.
- 154 children aged 6-12 years participated in the Kids4Fit program, led by a dietitian, physiotherapist, and child psychologist.
- Standardized BMI-z and waist circumference were measured at baseline, during the intervention, and at 52 weeks, analyzed using mixed-effects models.
Main Results:
- A non-significant trend towards lower BMI-z was observed up to 52 weeks post-intervention compared to the waiting list group.
- A significant reduction in waist circumference was found over time compared to the waiting list expectancy.
- No significant differences were observed in lifestyle factors or health-related quality of life.
Conclusions:
- The local multidisciplinary Kids4Fit intervention effectively reduced waist circumference in obese children from deprived areas.
- The intervention did not yield significant improvements in BMI-z, lifestyle, or quality of life compared to a waiting list control.
- Further research may be needed to enhance the program's impact on overall weight status and lifestyle behaviors.
Background:
GPs can refer obese children living in deprived areas to multidisciplinary programmes for a weight loss intervention, though the effectiveness of these local initiatives targeted to this specific group is unknown.
Objective:
To evaluate the effectiveness of the Kids4Fit intervention in deprived areas on child's weight status.
Methods:
Design and setting: cohort study, including a waiting list control period. Subjects: children (N = 154) aged 6-12 years, who signed up for the Kids4Fit intervention programme, led by a dietitian, physiotherapist and child psychologist were included. Measurements of standardized body mass index (BMI-z) and waist circumference were taken at start of the waiting list period, at start and at the end of the intervention and after 52 weeks. Mixed model analyses (random effects models) were used, expressed in effect per week [β with 95% confidence interval (CI)], compared to the waiting list expectancy over the 52-week study period.
Results:
Mixed model analyses showed a non-significant trend towards a lower BMI-z up to 52 weeks after start of Kids4Fit (β: -0.0024; 95% CI: -0.0053; 0.0004), compared to the waiting list expectancy. A significantly lower waist circumference was found over time compared to the waiting list expectancy (β: -0.0558; 95% CI: -0.0950; -0.0166). No differences were found in lifestyle and health-related quality of life.
Conclusion:
A local multidisciplinary intervention programme in deprived areas is effective in reducing waist circumference of obese children, compared to a waiting list expectancy, but no significant changes in lifestyle and quality of life were shown.
