title: Associations of serum minerals with body mass index in adult women.
abstract: OBJECTIVE
  This cross-sectional study evaluated the association between serum minerals and body mass index in adult women.
  
  
  METHODS
  One hundred and eighteen adult women were recruited by written advertisement from outpatient clinics or a health promotion center at a university hospital. Serum calcium, magnesium, copper and zinc were measured by an automatic analytical instrument and body mass index was calculated from height and weight.
  
  
  RESULTS
  Serum magnesium was inversely associated with body mass index (beta=-0.283, P=0.001) whereas serum copper had a positive association with body mass index (beta=0.197, P=0.025) after adjusting for age, physical activity, energy intake, dietary fat, alcohol consumption, supplements and menopause status. No associations were found with serum calcium and zinc.
  
  
  CONCLUSIONS
  Serum magnesium and copper may be involved in the regulation of body size in adult women.
