Iron and zinc status of women and men who followed cholesterol-lowering diets.

What Was Tested

This randomized controlled trial looks at Cholesterol, Dietary.

Paired t tests to compare preintervention and postintervention test results.

Two-sample t tests to compare gender, menopause status, and hormone-use groups.

Analysis of variance was performed to compare plasma zinc levels among diet-adherence subgroups.

Why It Was Studied

In this large-scale, 2-year prospective study of women and men, no adverse effects on intake or plasma indicators of iron and zinc were detected as a result of subjects being taught the NCEP step 2 diet.

Who Took Part

According to the abstract, 213 men were involved.

The age groups tagged for this paper are adults, both men and women.

Subjects attended 8 weeks of diet classes and followup counseling.

How the Study Was Run

The researchers set it up as a randomized study.

The men were allocated by chance, so the Cholesterol, Dietary group and the comparison group should start out alike.

Four-day food records, zinc protoporphyrin/ heme (ZPP/H, a measure of iron stores), hematocrit, and plasma zinc values were collected at baseline, 1 year, and 2 years.

What Was Measured
