title: Relationship between the change in overweight status from childhood to adolescence and metabolic syndrome phenotypes: a 9-year retrospective study.
abstract: OBJECTIVE
  To evaluate how the changes in overweight status from childhood to adolescence are related to metabolic syndrome phenotypes in adolescents.
  
  
  METHODS
  A total 375 adolescents aged 16 years. The overweight status from childhood to adolescence (from 7 years of age to 16 years) was determined by body mass index (BMI, kg/m(2)) calculated from records of the School Physical Examination data. The change in body weight was classified into four groups: normal weight to normal weight (NW-NW); overweight to normal (OW-NW); normal to overweight (NW-OW); overweight to overweight (OW-OW). Metabolic syndrome phenotypes were examined from a cross-sectional survey.
  
  
  RESULTS
  The mean values of all phenotypes except for body fatness (BMI and waist) and the cluster score of phenotypes at 16 years of age were not different between the NW-NW group and the OW-NW group, nor between the NW-OW group and the OW-OW group. However, the score as well as the level of body fatness and blood glucose were significantly different between current overweight and normal adolescents regardless of overweight status during childhood (P<0.05).
  
  
  CONCLUSIONS
  There was a linear relationship between overweight status during childhood and metabolic syndrome phenotypes in adolescence but current overweight status (adolescence overweight) was more closely related to the adolescent risk of metabolic syndrome than childhood overweight status.
