What This Paper Covers, in Plain Language
What It Covers
Researchers studied Vitamin D, K2, Magnesium and Zinc in this meta-analysis publication.
This systematic review and meta-analysis of published cross-sectional data was conducted to summarize the evidence on the link between serum vitamin D levels and BMI in adults.
Why It Was Studied
Although several cross-sectional studies have investigated serum vitamin D levels in relation to body mass index (BMI), findings are inconsistent.
Who the Included Studies Covered
PubMed tags the participants as both men and women.
The researchers found 34 articles that reported the correlation coefficients between serum 25-hydroxy vitamin D (25(OH)D) levels and BMI in apparently healthy adults (>18 years).
How the Review Was Done
PubMed, ISI Web of Science, Scopus and Google scholar database were searched to May 2012 for all relevant published papers.
The primary analysis was done on these 34 papers that reported 37 correlation coefficients.
To find the source of between-study heterogeneity, their secondary analysis was confined to eight studies that had used random sampling method and reported the correlations for the whole population.
What Was Measured
Although several cross-sectional studies have investigated serum vitamin D levels in relation to body mass index (BMI), findings are inconsistent.
PubMed files the paper under topics including Body Mass Index, Cross-Cultural Comparison, Cross-Sectional Studies, Developing Countries, Sex Factors and Vitamin D.
