Purpose: Obesity is a frequent nutritional disorder in children and adolescent and its prevalence is increasing in Korea. The aim of this study was to measure body composition using bioelectrical impedence in primary, middle, high and college students in Cheju.
Methods: We measured height, weight, and body composition (Fat o, WHIZ, Fat fee mass) by InBody 3.0 in 1,431 students aged 10-25 years. We also examined degree of obesity comparing standard weight for height, body mass index, and percent of body fat.
Results: Fat free mass increased by aging in both sex, higher in male. Fat mass was highest in Primary school in male (12.09±4.86kg), college in female (16.03±4.22kg). Percent of body fat was highest in primary student (21.64±8.02%), decreased middle (19.96±7.26%), high school (15.07±5.13%), and increased in college student (17.33±5.21%) in male, however, lowest in primary student (22.78±6.10%), increased by aging (middle; 25.38±6.19%, high; 27.61±5.27%, college; 28.27±4.49%) in female. Percent of body fat was significantly higher in female except in primary school age.
The prevalence of obesity based on fat % was highest in primary school student (primary, middle, high, college student; 33.3%, 23.3%, 7.6%, 8.2%) in male (>25%), and highest in college student (11.1%, 26.6%, 32.3%, 38.6%) in female (>30%), whereness, based on a standard weight for height (>20%), 13.16%, 10.84%, 6.90%, 10.10% in male, 4.44%, 7.21%, 12.11%, 9.59% in female.
Conclusion: It was necessary to evaluate obesity degree by body fat percentage, especially in adolescent and young female
