Abstract Summary

Objective: This study investigates the effects of Zinc supplementation on immune function and infection rates in elderly adults.

Context: Zinc is known for its role in immune function. This study explores how Zinc affects immune response and infection prevention in the elderly.

Methods Used

Approach: The study uses a randomized, double-blind, placebo-controlled trial. Elderly participants were divided into two groups, receiving either Zinc supplements or a placebo for six months. Immune function and infection rates were assessed.

Data Collection: Immune function was evaluated through blood tests at baseline, three months, and six months, measuring markers such as white blood cell count and cytokine levels. Infection rates were recorded through participant self-reports and clinical records. The differences between the Zinc and placebo groups were analyzed.

Researchers' Summary of Findings

Impact on Health: The research shows that Zinc supplementation enhances immune function, with higher white blood cell counts and improved cytokine profiles. Infection rates were lower in the Zinc group compared to the placebo group.

Health Implications: Regular Zinc supplementation may bolster immune defenses and reduce the incidence of infections in the elderly, contributing to better overall health and reduced healthcare costs.
