Effects of a controlled trial of a school-based exercise program on the obesity indexes of preschool children.
Exercise has been found to be effective for prevention of weight gain and maintenance of a stable weight in adults.
The objective of this study was to evaluate the effect of a school-based aerobic exercise program on the obesity indexes of preschool children.
Subjects were 292 second-year elementary school pupils from 2 kindergartens in Hat Yai municipality.
Songkhla province, southern Thailand.
A specially designed exercise program, including a 15-min walk before beginning the morning class and a 20-min aerobic dance session after the afternoon nap, 3 times a week, was conducted for 29.6 wk.
Weight, height, and triceps skinfold thickness were measured 4 times.
At the end of the study, the prevalence of obesity, using 95th percentile National Center for Health Statistics triceps-skinfold-thickness cutoffs, of both the exercise and control groups decreased.
That of the exercise group decreased from 12.2% at baseline to 8.8% (Wilcoxon signed-rank test, P=0.058), whereas that of the control group decreased from 11.7% to 9.7% (Wilcoxon signed-rank test, P=0.179).
A sex difference in the response of body mass index (BMI) to exercise was observed.
Girls in the exercise group had a lower likelihood of having an increasing BMI slope than the control girls did (odds ratio : 0.32 ; 95% Cl : 0.18,0.56).
In conclusion, our study suggests that a 29.6-wk school-based exercise program can prevent BMI gain in girls and may induce a remission of obesity in preschoolage children. (...)
