title: The effect of a weight management program on postural balance in obese children.
abstract: The present study aimed to investigate whether obese children improve their balance and postural performance following a 6-month-weight management program. Twenty-nine obese children aged 6-14 years were examined posturographically before and after participation in weight management program. The interactive balance system evaluated the stability index, Fourier spectral analysis, weight distribution index, and falling index. The performance was evaluated for eight positions requiring closure of eyes, standing on pillows, as well as head turns. Anthropometric measurements (e.g., weight, height, BMI, and BMI percentiles) were also determined before and after the intervention. We found significant increase in height and significant decreased in BMI percentile following the intervention program (p<.05). Pre-intervention BMI percentile was found to be correlated with stability index in most of the positions measured (e.g., normal open position=.464; p=.011). Following the intervention program, an interaction was found between BMI percentile differences (pre- versus post-interventional) and balance (stability index and F2-F4 frequencies of most standing positions). Furthermore, a correlation was found between general stability and the falling index (.446; p=.015). Regression analysis showed that only initial weight distribution index and post-intervention BMI entered the equation as predictors of post-intervention weight distribution index.
  
  
  CONCLUSIONS
  Weight management program for childhood obesity improved stability, reduced potential vestibular stress/disturbances, and decreased falling probability of the participants. Further longitudinal studies are needed to verify the relationship between physical activity, weight loss, and reduction of subsequent injuries in obese children.
