Trial of zinc supplements in relation to pregnancy outcomes, hematologic indicators, and T cell counts among HIV-1-infected women in Tanzania.

What Was Tested

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

The researchers examined the effects of zinc supplements on birth outcomes, hematologic indicators, and counts of T lymphocyte subsets among 400 HIV-infected pregnant women.

Why It Was Studied

Such endpoints may affect the risk of adverse birth outcomes among HIV-infected women.

Who Took Part

PubMed indexes the participants as adults, women only.

All women received iron, folic acid, and multivitamin supplements irrespective of the experimental assignment.

How the Study Was Run

The researchers set it up as a randomized 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.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

Such endpoints may affect the risk of adverse birth outcomes among HIV-infected women.

PubMed files the paper under topics including Birth Weight, CD4-CD8 Ratio, HIV Infections, HIV-1, Pregnancy Outcome, Prenatal Care and T-Lymphocyte Subsets.
