This study sought to examine how the change in overweight status from childhood to adolescence is related to metabolic syndrome phenotypes in adolescents over a period of 9 years. To achieve this objective, 154 Korean students in 1996 and 221 in 1997, aged 16 years at the time, were studied. The mean body mass index and prevalence of overweight increased linearly in both boys and girls over time. The prevalence of overweight at 16 years of age was about two times greater than the prevalence at 7 years of age. Current overweight status had stronger ties to the metabolic syndrome phenotypes of adolescence than the change in overweight status from childhood to adolescence. In conclusion, study results showed that there was a linear relationship between overweight status during childhood and metabolic syndrome phenotypes in adolescence, but current overweight status was more closely related to adolescent metabolic syndrome risk than childhood overweight status.
