Reference Values of Body Composition Indices: The Korean National Health and Nutrition Examination Surveys

Abstract

PurposeAn increase in the prevalence of obesity has been observed in children and adolescents. As remarkable changes in body composition occur with growth during the adolescent period, it is important that changes in body composition be monitored. The purpose of this study was to propose reference percentile values for body composition indices including body mass index (BMI) in children and adolescents in Korea.Materials and MethodsThis study was performed using data from the Fourth and Fifth Korea National Health and Nutrition Examination Surveys. Body composition data were obtained using dual-energy X-ray absorptiometry. The percentile curves of body composition indices were constructed by the LMS method.ResultsA total of 2123 children and adolescents between the ages of 10 and 19 years were included in this study. We obtained the percentile curves for BMI and body composition indices.ConclusionThe reference values for body composition from this study could help with assessing body composition in Korean adolescents.

Body fat percentage in adolescents from Curitiba-PR metropolitan region: reference data using LMS method

“…For those who had DXA as a reference: Park et al 11 evaluated 689 asian teenagers aged between 12 and 16 years who reported a decrease of the %BF in this age range, as shown in our results. In the 50 th percentile the values varied from 25.2% to 19.4%; in the 90 th percentile the values varied between 37.1% and 29.5%.…”

“…Around the world, studies of reference values based on fat percentage of children and adolescents obtained through ST were related in Germany (3-18 years) 5 ; Canada (6-19 years) 7; United States (5-18 years) 8 ; Turkey (6-18 years) 9; Brazil (7-10 years old) 19 and India (10-19 years) 11 . On the other hand, studies that used DXA were found of the population of Denmark (8-14 years) 2) ; United States (8-19 years) 25 and Korea (10-18 years) 10 (10-19 years) 11 .…”

“…In this study the values varied between 27.22-17.45% (50 th percentile) and 37.71-22.80% (90 th percentile). The %BF values reduction could be explained could be explain by the physiological tendency to increase the lean mass and reduce the fat mass of puberty 11 . Corroborating this information, a North American study of 8,269 children and adolescents (5 to 18 years) found that the peak of %BF was in the range of 11-12 years for boys with subsequent decrease in ages 26 .…”

“…Regarding its diagnosis, several direct and indirect methods are applied in clinical practice of body fat assessment. Furthermore, the body-mass index (BMI), the skinfold thickness (ST) and the bioelectrical impedance analysis (BIA) are the most common methods applied to children and adolescents [5][6][7][8][9][10][11][12][13] .…”

“…Signs of portal hypertension, such as splenomegaly, ascites or varices, were collected based on the US, clinical or endoscopic results. Body mass index (BMI) at the time of 2D SWE was defined as normal for percentiles lower than 85, overweight for percentiles between 85 and 95, and obese for percentiles of 95 or higher [22,23].…”
