Association between dietary mineral nutrient intake, body mass index, and waist circumference in U.S. adults using quantile regression analysis NHANES 2007–2014

Abstract

Objective Mineral nutrients play an important role in maintaining material and energy metabolism. Reports on mineral nutrient intakes and body mass index (BMI) and waist circumference (WC) are rare in the United States. This study examined the relationship between BMI, WC and dietary mineral intakes. Method We used the data from National Health and Nutrition Examination Survey 2007–2014. Nutrient intakes were adjusted for energy according to the residual adjustment method. We used the quantile regression model to analyze the relationship between BMI, WC under different distributions and the average daily mineral intakes. Result A total of 19,952 people were included in the study, including 9,879 men and 10,073 women (≥20 years old). The median BMI was 27.935 kg/m2 and the median WC was 97.700 cm. The results of quantile regression showed that calcium, magnesium, potassium, copper, zinc and iron intakes were negatively correlated with BMI and WC, after adjusting for age and gender. Sodium and phosphorus intakes were positively correlated with BMI, sodium intakes were positively correlated with WC. This correlation was enhanced with increasing quantiles of risk levels. In high BMI or high WC populations, mineral intakes had a greater impact on BMI and WC. The quantile regression coefficients of selenium intakes were not statistically significant at each quantile. Conclusion Our results suggested that the mineral nutrient intakes were associated with BMI and WC in American adults. However, we also need to further study the longitudinal effects of mineral intakes and obesity.

Correlation of serum magnesium levels with body mass index in post-menopausal women: an observational study

“…7 National health and nutrition examination survey highlights that magnesium deficiency is prevalent among the obese subjects. 8,10 We found an inverse relationship between the serum magnesium levels with body mass index in our study. (r=-0.83; p value<0.001).…”

“…Studies have suggested that there is relation between magnesium deficiency and obesity status among this group of women. [5][6][7][8]10 We conducted this study to explore the correlation of body mass index with serum magnesium levels.…”

“…A study by Yadav et al reported that they had high negative correlation between the serum magnesium levels and body mass index in their study (r=-0.92; p<0.001). 5 6,8,[17][18][19][20] Our study had some limitations. Firstly, small sample size, larger multi centeric studies have is conducted to understand the exact correlation of magnesium deficiency with obesity.…”

“…2 There are reports suggested the link of serum magnesium levels and estrogen levels in post-menopausal women. [5][6][7][8] So, we conducted this study with a goal of correlating serum magnesium levels with body mass index in postmenopausal women.…”

Magnesium in Obesity, Metabolic Syndrome, and Type 2 Diabetes

“…As a consequence, obese subjects are often Mg 2+ deficient [ 39 ]. Indeed, the National Health and Nutrition Examination Survey (NHANES) 3 study underlines that Mg 2+ deficit is more prevalent in subjects with body mass index (BMI) in the obese range than in the normal American population [ 40 , 41 ]. Analogously, Mg 2+ intake is impaired in 35% of French individuals with BMI > 35 kg/m 2 [ 42 ].…”
