Abstract

Introduction

Vitamin D deficiency and type 2 diabetes are common among Hispanics and African Americans in the US. The aim of the study was to determine the effect of supplemental vitamin D intake (4000 IU/day or 6000 IU/day of vitamin D3 over a 6-month period) on blood lipids in a sample of African Americans and Hispanics with type 2 diabetes and vitamin D insufficiency.

Materials and methods

Participants (n = 75) were recruited by community outreach. Participants in both groups were required to take either 4000 IU or 6000 IU of vitamin D (Cholecalciferol) per day given in the form of a pill in a single daily dose. Mixed model was used to compare treatment effects (4000 IU vs. 6000 IU) on the outcome variables. Bonferroni multiple comparison test was used to detect significant changes from baseline, 3 months, and 6 months.

Results

A significant decrease in total cholesterol (from 193.88 ± 41.03 to 180.48 ± 27.53 mg/dl, P = 0.040) and triglycerides (from 201.44 ± 91.35 to 172.92 ± 76.87 mg/dl, P = 0.037) was found for the 6000 IU group at 6 months. The significance was lost after adjusting for confounders.

Conclusion

Our results suggest that the positive effect of vitamin D supplementation on lipid profile may be mediated by other cofactors related to vitamin D metabolism among Hispanic and African American participants with type 2 diabetes.
