Insights
A screening and treatment program effectively prevented mildly overweight children from becoming more obese. The intervention group showed significantly lower rates of worsening overweight indices compared to the control group.
Area of Science:
- Pediatric Obesity Research
- Public Health Interventions
Background:
- Rising obesity rates in elementary school children, including mild cases.
- Need to evaluate interventions for overweight children.
Purpose of the Study:
- To determine if screening and treatment programs prevent overweight elementary school children from worsening their condition.
Main Methods:
- 40 overweight children in screening and treatment programs (subjects).
- 240 children in screening program only (controls).
- Observation periods of 14 months (subjects) and 12 months (controls).
Main Results:
- Subjects had significantly lower incidence of worsening overweight indices (5/40 vs 133/240).
- Subjects significantly reduced mean percent relative body weight (%RBW).
- Controls significantly worsened mean %RBW.
Conclusions:
- The treatment program is crucial for preventing the progression of overweight conditions in mild cases.
- Intervention demonstrates effectiveness in managing childhood obesity.
Background:
A follow-up study has reported that not only highly obese but also mildly obese children are becoming heavier during the elementary school children. Then we determined the effect of programs for the screening and treatment of overweight elementary school children whether the programs prevented mildly overweight children from development of more overweight condition.
Methods:
Subjects were 40 overweight children who participated in both screening and treatment programs. As controls, only 240 children who participated in the screening program were used. The mean observation periods of the subjects and controls were 14 and 12 months, respectively.
Results:
In both groups, older and heavier children significantly decreased their indices of overweight (percent relative body weight; %RBW), indicating that mildly obese children worsened their %RBW. However, the incidence of children who worsened their %RBW was significantly lower in the subjects (5 of 40) than in the controls (133 of 240) (P < 0.0001). Finally, the subjects significantly reduced their mean %RBW (P < 0.0001) and the controls significantly worsened it (P = 0.0093).
Conclusion:
The treatment program was found important because it prevents mildly overweight children who may worsen their overweight indices without the program from developing more overweight condition.
