Effect of vitamin D supplementation on type 2 diabetes biomarkers: an umbrella of interventional meta-analyses.

ABSTRACT:

Background

Vitamin D supplementation exerts several supporting effects on improving glycemic status, however, results are inconclusive. Thus, in the present study, we aimed to conduct an umbrella of meta-analysis regarding the impact of vitamin D on type 2 diabetes (T2DM) biomarkers.

Methods

The Scopus, PubMed, Web of Science, Embase, and Google Scholar online databases were searched up to March 2022. All meta-analyses evaluating the impact of vitamin D supplementation on T2DM biomarkers were considered eligible. Overall, 37 meta-analyses were included in this umbrella meta-analysis.

Results

Our findings indicated that vitamin D supplementation significantly decreased fasting blood sugar (FBS) (WMD = - 3.08; 95% CI: - 3.97, - 2.19, p < 0.001, and SMD = - 0.26; 95% CI: - 0.38, - 0.14, p < 0.001), hemoglobin A1c (HbA1c) (WMD = - 0.05; 95% CI: - 0.10, - 0.01, p = 0.016, and SMD = - 0.16; 95% CI: - 0.27, - 0.05, p = 0.004), insulin concentrations (WMD = - 2.62; 95% CI: - 4.11, - 1.13; p < 0.001, and SMD = - 0.33; 95% CI: - 0.56, - 0.11, p = 0.004), and homeostatic model assessment for insulin resistance (HOMA-IR) (WMD = - 0.67; 95% CI: - 1.01, - 0.32, p < 0.001, and SMD = - 0.31; 95% CI: - 0.46, - 0.16, p < 0.001).

Conclusion

This umbrella meta-analysis proposed that vitamin D supplementation may improve T2DM biomarkers.

Project description:ObjectiveTo summarise the evidence of associations between dietary factors and incidence of type 2 diabetes and to evaluate the strength and validity of these associations.DesignUmbrella review of systematic reviews with meta-analyses of prospective observational studies.Data sourcesPubMed, Web of Science, and Embase, searched up to August 2018.Eligibility criteriaSystematic reviews with meta-analyses reporting summary risk estimates for the associations between incidence of type 2 diabetes and dietary behaviours or diet quality indices, food groups, foods, beverages, alcoholic beverages, macronutrients, and micronutrients.Results53 publications were included, with 153 adjusted summary hazard ratios on dietary behaviours or diet quality indices (n=12), food groups and foods (n=56), beverages (n=10), alcoholic beverages (n=12), macronutrients (n=32), and micronutrients (n=31), regarding incidence of type 2 diabetes. Methodological quality was high for 75% (n=115) of meta-analyses, moderate for 23% (n=35), and low for 2% (n=3). Quality of evidence was rated high for an inverse association for type 2 diabetes incidence with increased intake of whole grains (for an increment of 30 g/day, adjusted summary hazard ratio 0.87 (95% confidence interval 0.82 to 0.93)) and cereal fibre (for an increment of 10 g/day, 0.75 (0.65 to 0.86)), as well as for moderate intake of total alcohol (for an intake of 12-24 g/day v no consumption, 0.75 (0.67 to 0.83)). Quality of evidence was also high for the association for increased incidence of type 2 diabetes with higher intake of red meat (for an increment of 100 g/day, 1.17 (1.08 to 1.26)), processed meat (for an increment of 50 g/day, 1.37 (1.22 to 1.54)), bacon (per two slices/day, 2.07 (1.40 to 3.05)), and sugar sweetened beverages (for an increase of one serving/day, 1.26 (1.11 to 1.43)).ConclusionsOverall, the association between dietary factors and type 2 diabetes has been extensively studied, but few of the associations were graded as high quality of evidence. Further factors are likely to be important in type 2 diabetes prevention; thus, more well conducted research, with more detailed assessment of diet, is needed.Systematic review registrationPROSPERO CRD42018088106.
