Correlates and prevalence of insufficient 25-hydroxyvitamin D status in black and white older adults: the health, aging and body composition study.

ABSTRACT:

Objectives

To determine the prevalence and correlates of vitamin D insufficiency in black and white older adults.

Design

Cross-sectional.

Setting

Health, Aging and Body Composition Study.

Participants

Nine hundred seventy-seven black and 1,604 white adults aged 70 to 81.

Measurements

Logistic regression and classification and regression tree analysis were used to identify correlates of vitamin D insufficiency (25-hydroxyvitamin D (25(OH)D) <30 ng/mL) separately in blacks and whites.

Results

The prevalence of 25(OH)D insufficiency was 84% in blacks and 57% in whites. Seventy-six percent of blacks and 56% of whites did not take a multivitamin; those who did not take a multivitamin were more likely to be vitamin D insufficient (odds ratio (OR)=5.17 (
