Vitamin D supplementation reduces the risk of fall in the vitamin D deficient elderly: An updated meta-analysis.

What It Covers

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a meta-analysis.

However, considerable controversy exists regarding the association of such supplementation and fall risk.

Furthermore, some studies published recently were not included in the previous meta-analyses.

Who the Included Studies Covered

The age groups tagged for this paper are older adults and people over 80, both men and women.

Randomized clinical trials (RCTs) reporting the effect of vitamin D supplementation alone or with calcium on fall incidence were selected from studies.

How the Review Was Done

The researchers systematically searched several literature databases including PubMed and the Embase from inception to September 2020.

The protocol for this meta-analysis was registered with PROSPERO (CRD42021226380).

Qualitative and quantitative information was extracted; the random-effects model was conducted to pool the data for fall; statistical heterogeneity was assessed using the I2 test and potential for publication bias was assessed qualitatively by a visual estimate of the funnel plot and quantitatively by calculation of the Begg's test and the Egger's test.

What Was Measured

PubMed files the paper under topics including Accidental Falls, Dietary Supplements, Vitamin D, Vitamin D Deficiency and Vitamins.

Author keywords: Calcium, Meta-analysis and Randomized-controlled trials.
