Vitamin D supplementation improves waist-to-hip ratio and fasting blood glucose in vitamin D deficient, overweight or obese Asians: A pilot secondary analysis of a randomised controlled trial
Abstract
Recent trials do not support a role for vitamin D supplementation in prevention or treatment of type 2 diabetes mellitus, although effects may differ in Asian populations. In this pilot secondary analysis of a placebo-controlled randomised trial of overweight or obese individuals with low 25-hydroxyvitamin D (25(OH)D 0.05). In conclusion, vitamin D supplementation improved waist-hip ratio and fasting blood glucose in overweight and obese Asian-Australians with low vitamin D concentrations. Further research is required to determine whether vitamin D supplementation is potentially more effective in specific ethnic groups.
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 65 participants or records.
