[A cross-sectional study on relationships between daily physical activity and concentration of serum cholesterol and body mass index in fifth grade elementary schoolchildren and their parents].
The purpose of this study was to estimate the effects of daily physical activity on serum total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C), body mass index (BMI) and atherogenic index (AI) in 240 fifth grade schoolchildren, their 174 fathers and 212 mothers. Information on daily physical activity was obtained by inquiry with a questionnaire and was also measured directly with a device sensing acceleration of physical movement. In schoolchildren, effect of physical activity on TC, HDL-C and AI was not apparent, but that on BMI was shown. In adult men, HDL-C differed by job classification and increased as the degree of physical labor increased from desk work to light and heavy work. Strength of physical activity using the quotient of total amount of measured physical activity divided by body weight had a significant positive correlation with serum HDL-C (r = 0.20, p < 0.05) and significant negative correlation with AI (r = -0.18, p < 0.05) in adult men. In adult women, daily physical activity did not have a significant correlation to TC, HDL-C, AI or BMI. These results appear to suggest that the effect of daily physical activity on serum cholesterol, AI, BMI of schoolchildren and adult women was smaller than that for adult men.
