Insights
Hospital-based lifestyle modification (LM) programs show lasting benefits for obese children and adolescents. The study found significant reductions in body mass index (BMI) and BMI z-score in participants completing the LM program.
Area of Science:
- Pediatric Endocrinology
- Obesity Management
- Public Health
Background:
- Lifestyle modification (LM) is a primary strategy for managing childhood obesity.
- This study evaluates the long-term impact of a hospital-based LM program on pediatric participants.
Purpose of the Study:
- To assess the sustained effects of a multidisciplinary LM program on body mass index (BMI) and BMI z-score in overweight/obese children and adolescents.
Main Methods:
- A cohort of 120 overweight/obese children and adolescents (aged 5-18) enrolled in a hospital-based LM program.
- Data on weight and height were collected at 6, 12, and 18 months post-initial visit.
- Changes in BMI and BMI z-score were analyzed, comparing participants who completed >1 month of LM with a hospital-control group.
Main Results:
- The LM group showed significant BMI reductions at 6 and 12 months compared to the hospital-control group.
- Both groups exhibited a downward trend in BMI z-score, with a more pronounced reduction in the LM group at 6 months.
- BMI decline was greater in adolescents than in younger children, indicating age-related variations.
Conclusions:
- Completion of the hospital-based LM program leads to sustained improvements in BMI and BMI z-score.
- The findings support the long-term efficacy of structured LM interventions for pediatric obesity.
Background:
Lifestyle modification (LM) is the mainstay in the management of obese children. This study aimed to investigate the long-term effects of a pediatric cohort participating in a hospital-based LM program.
Methods:
Overweight/obese children and adolescents who visited a multidisciplinary LM program "The Health and Vitality Clinic" were included. Data on weight and height were collected at 6, 12, and 18 months following the initial visit. The changes in body mass index (BMI) and BMI z-score were analyzed.
Results:
A total of 120 participants aged 5-18 years who visited the clinic were included. Sixty-one subjects who completed > 1 months (up to a maximum of 5 months) of the LM program constituted the LM group, while those who visited the clinic once were characterized as hospital-control (HC) group. There was a significant reduction in BMI at 6 and 12 months in the LM group, and at 6 months in the HC group, with a greater reduction observed in the LM group at 6 and 12 months (-1.05 ± 1.46 vs. -0.42 ± 1.21, p = 0.027; -0.87 ± 1.46 vs. -0.14 ± 1.43, p = 0.038, respectively). Both groups showed a downward trend in BMI z-score at 6, 12, and 18 months, with the LM group showing a greater reduction at the 6 months (-0.33 ± 0.28 vs. -0.22 ± 0.18, p = 0.019). BMI decline was more pronounced in adolescents than in children, showing variations in weight gains based on age.
Conclusions:
The study demonstrated lasting effects in BMI and BMI z-score following the completion of the LM program.
