Objective: This cross-sectional study evaluated the association between serum [blood] 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 [simple numeric measure of “fatness” or “thinness”] was calculated from height and weight.
Serum magnesium was inversely associated with body mass index (beta =-0.283, P=0.001) [higher magnesium, lower BMI], whereas serum copper had a positive association with body mass index (beta =0.197, P=0.025) [higher copper, higher BMI] 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.
Conclusion: Serum magnesium and copper may be involved in the regulation of body size in adult women.
