Abstract

Objectives The purpose of this study is to investigate the relationship between physical activity and growth indices. Methods 5963 of 12 years old adolescents were participated in the 10th Korea Youth Risk Behavior Web-Based Survey (KYRBWS-V) project in 2014. These data was analyzed to show the relationship between physical activity and height, BMI. Results According to the Physical Activity guidelines, the mean height was higher in the each male and female group with ‘moderate physical activity for at least 60 min ≥ 7 days/week’, ‘vigorous physical activity ≥ 3 days/week’, and ‘muscle-strengthening activity ≥ 3 days/week’ compare to the group who did not. The mean BMI was lower in the male group of ‘sitting for watching TV or computer, etc on a weekday ＜ 3 hr/day’ compare to group who did not. Conclusions These results showed that physical activity in adolescence is correlated to growth. Therefore, this research can be one of the reference data to show the proper physical activity is important in the growth.
