What This Study Did, in Plain Language

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

Objective measures of neuromuscular strength [Short Physical Performance Battery (SPPB), grip strength and 6-minute walking distance (6MWD)] and bone mineral density (BMD) were obtained.

Why It Was Studied

This information in older African Americans (AAs) is sparse.

Who Took Part

According to the abstract, 260 women were involved.

The age groups tagged for this paper are middle-aged adults and older adults, women only.

260 healthy AA women aged >60years were assigned to receive placebo or vitamin D3.

Subjects with baseline 25OHD levels ≤8ng/ml or ≥26ng/ml were excluded.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

Some women received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

Topics PubMed links to this paper include Black or African American, Body Weights and Measures, Bone Density, Calcifediol, Cholecalciferol, Health Behavior and Muscle Strength.

Author keywords: Free vitamin D, Physical performance and Vitamin D.
