The study was conducted to comprehensively assess the association of the concentration of vitamin D in the blood and insulin resistance in non-diabetic subjects. The objective was to pool the results from all observational studies from the beginning of 1980 to August 2021. PubMed, Medline and Embase were systematically searched for the observational studies. Filters were used for more focused results. A total of 2248 articles were found after raw search which were narrowed down to 32 articles by the systematic selection of related articles. Homeostatic Model Assessment of Insulin Resistance (HOMAIR) was used as the measure of insulin resistance and correlation coefficient was used as a measure of the relationship between vitamin D levels and the insulin resistance. Risk of bias tables and summary plots were built using Revman software version 5.3 while Comprehensive meta-analysis version 3 was used for the construction of forest plot. The results showed an inverse association between the status of vitamin D and insulin resistance (r = -0.217; 95% CI = -0.161 to -0.272; = 0.000). A supplement of vitamin D can help reduce the risk of insulin resistance; however further studies, like randomized controlled trials are needed to confirm the results.
本研究旨在全面评估非糖尿病患者血液中维生素 D 浓度与胰岛素抵抗之间的关联。目的是汇总 1980 年初至 2021 年 8 月所有观察性研究的结果。通过系统搜索 PubMed、Medline 和 Embase 中的观察性研究,使用了过滤器以获得更有针对性的结果。经过原始搜索,共发现 2248 篇文章,通过系统选择相关文章,将其缩小到 32 篇。稳态模型评估的胰岛素抵抗(HOMAIR)被用作胰岛素抵抗的衡量标准,相关系数被用作衡量维生素 D 水平与胰岛素抵抗之间关系的指标。使用 Revman 软件版本 5.3 构建偏倚风险表和总结图,使用 Comprehensive Meta-Analysis 版本 3 构建森林图。结果表明,维生素 D 状态与胰岛素抵抗呈负相关(r = -0.217;95%CI = -0.161 至 -0.272;P = 0.000)。补充维生素 D 有助于降低胰岛素抵抗的风险;然而,需要进一步的研究,如随机对照试验,以确认这些结果。
