The purpose of this study was to examine whether physical activity (PA) and a sedentary behavior were related to weight status in Korean adolescents. 72,399 students in grades 7th to 12th participated in the 5thKorea Youth Risk Behavior Web-based Survey (KYRBWS-V) project in 2009. Body mass index (BMI), PA, and sedentary behavior were assessed by KYRBWS-V. The study results show that the boys had higher PA and less sedentary behavior than did the girls (p<0.01). The amounts of vigorous PA (p<0.001), moderate PA (p<0.001), moderate PA for at least 60 min (p<0.001), exercise for muscular strength (p<0.001), walking on a weekday (p<0.001), and walking on a weekend (p=0.012) were less in boys who were more obese than the other boys. The time spent sitting on a weekday (p<0.001) and weekend (p<0.001) was higher in more obese individuals in boys. Exercise for muscular strength (p=0.011) was less in girls who were more obese. The time spent sitting on a weekday (p=0.005) and weekend (p<0.001) was higher in more obese individuals in girls. However, vigorous PA (p<0.001), moderate PA (p<0.001), moderate PA for at least 60 min (p=0.003), walking on a weekday (p<0.001) was higher for the more obese girls. PA and sedentary behavior could be each independent factors that reduce or prevent obesity in Korean adolescents.
