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 (b ¼ À0.283, P ¼ 0.001) whereas serum copper had a positive association with body mass index (b ¼ 0.197, P ¼ 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. Conclusion: Serum magnesium and copper may be involved in the regulation of body size in adult women.

Determinants of serum zinc concentrations in a population of French middle-age subjects (SU.VI.MAX cohort)

“…It has also been suggested that differences in BMI could explain the lower serum zinc concentrations in women than in men. Although BMI was higher in men than in women, our results did not evidence any differences in serum zinc concentration according to BMI in agreement with some previous reports (Hashim et al, 1996;Benes et al, 2005;Song et al, 2007). Our results highlighted smoking and education as other significant determinants of serum zinc levels only in women.…”

Hypomagnesemia and its relation with chronic low-grade inflammation in obesity

“…27 hypoMagneseMia and loW-grade chronic inflaMMation The literature has shown that the diet of obese individuals has reduced magnesium content, which is a nutritional problem of great relevance. 28,29 Huang et al 30 and Song et al 31 found that dietary intake of magnesium is inversely proportional to body mass index, waist circumference, and body fat percentage.…”

High Dietary Magnesium Intake is Significantly and Independently Associated with Higher Insulin Sensitivity in a Mexican-Mestizo Population: A Brief Cross-Sectional Report

“…Conversely, other studies demonstrated an inverse correlation between serum Mg concentration and BMI 39,40 . a possible explanation of these findings is that they used serum Mg instead of daily Mg dietary intake.…”
