title: Birth Weight Could Influence Bone Mineral Contents of 10- to 18-Year-Old Korean Adolescents: Results from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010.
abstract: BACKGROUND
  We investigate the relationship between birth weight (BW) and bone mineral content (BMC) in Korean adolescents.
  
  
  METHODS
  Data were obtained from the Korea National Health and Nutrition Examination Survey conducted in 2010. Baseline characteristics were compared according to age- and sex-specific BMC quartiles of total body less head (TBLH), lumbar spine (LS) and femur neck (FN) in 10- to 18-year-old adolescents (male = 474, female = 394).
  
  
  RESULTS
  BW showed a positive correlation with current weight-SDS (p = 0.006 in males, p = 0.008 in females). BW according to TBLH-BMC quartile groups (p for trend <0.003 in males, <0.0001 in females), LS-BMC quartile groups (p for trend <0.034 in males) and FN-BMC quartile groups (p for trend <0.008 in males, <0.020 in females) showed significant differences. The odds ratio (OR) of being in the highest BMC quartile, per 1-kg increase in BW, was significantly increased in TBLH-BMC (OR = 2.14 in males, OR = 3.26 in >16-year-old adolescents) and FN-BMC (OR = 2.62 in males, OR = 3.06 in >16-year-old adolescents) after adjusting for age, height, smoking, drinking, metabolic equivalent of task, and gestational age.
  
  
  CONCLUSIONS
  BW might be one of the determinant factors of BMC in Korean adolescents.
