We studied the association of body weight and height of school children with their birth weight, birth height, increase of BMI, body weight of their parents, eating habits, and physical activity by multiple regression analysis. Using present body weight of school children as a dependent variable, only the BMI of mothers showed a significant association among independent variables (corrected R<SUP>2</SUP>=0.751) . Birth weight of school children was not significantly associated. Analysis by age revealed a significant relationship of body weight at 13 years with BMI of the mother. As for lifestyle parameters, there was a significant correlation of present body weight of school children with frequency of physical activity of the fathers. Birth weight and sleep time showed no significant correlation. Using the present height of school children as a dependent variable, the BMI of mothers showed a significant positive relationship and the BMI of fathers showed a significant negative relationship as independent variables. Since this study followed long period of time (up to 15 years), the results showed a low response rate of 44.5 % and a small number of subjects for the analysis. Nevertheless, we found a few factors which were significantly associated with physical parameters of school children by multiple regression analysis. Further studies on a large scale will be necessary to find other related factors.
