<b><i>Aims:</i></b> To date, it is largely unknown how body mass index (BMI), gestational weight (GW), and stored vitamin D (25(OH)D) levels change in the vitamin D-supplemented gestational diabetes mellitus (GDM) patients, irrespective of their pre-pregnancy BMI. Therefore, to study this association, a prospective systematic review and meta-analysis protocol is proposed here. <b><i>Methods:</i></b> Primarily, different databases (PubMed, Embase and Scopus) will be searched (without any limitation to date or language) for randomised parallel-arm trials comparing GW, BMI and stored vitamin D level in the body among GDM patients who were supplemented and not supplemented with vitamin D, besides their conventional GDM care. The study selection process and the consecutive risk of bias assessment will adhere to the PRISMA 2009 flow chart and the Cochrane collaboration’s guideline, respectively. These interventions’ effect on the respective outcomes will be compared by meta-analysis (along with an assessment of the statistical heterogeneity) when comparable data will be available from at least 4 studies. Subgroup analysis and Egger’s meta-regression will follow if an adequate number of trials are available. Narrative reporting will be considered when a quantitative comparison is not feasible for any of the outcomes. <b><i>Conclusion:</i></b> The proposed review aims to compare the BMI, GW, and 25(OH)D levels in the blood between the vitamin D supplemented and not supplemented GDM patients.

Objective: on the basis of a systematic review, clarify the role of overweight and obesity as a predictor of gestational diabetes mellitus (GDM). Materials and methods: an analysis of the literature data of the leading bibliographic sources - MEDLINE, Cochrane col., EMBASE. To evaluate the body mass index and standards of weight gain during pregnancy used the WHO guidelines and criteria of the Institute of Medicine (2009). The frequency and the odds ratio (OR) of developing GDM was estimated separately for each of the three groups in BMI. Results: A systematic review included 23 different design studies involving 740 510 women. It was found that the odds ratio of the risk of GDM in a group of pregnant women with excess weight is doubled - 2.22 (95 % CI 1.72 - 3.64), and almost four in obesity - 3.88 (95 % CI 2.97 - 5.32). The incidence of GDM in a group of pregnant women with normal body mass index - 3.77 % in the group with excess body weight - 6.59 %, in the group with obesity - 9.88 %. Conclusions: The obtained strong evidence of a direct connection between the linear increase in maternal BMI and the risk of developing gestational diabetes. Pregnant women with excess weight and obesity are at high risk for carbohydrate disorders during pregnancy.

(1) Background: Studies on the association between Vitamin D receptor gene polymorphism and gestational diabetes mellitus have been inconsistent. The aim of this study was to summarize available evidence on the association between polymorphisms of Vitamin D receptor genes and susceptibility to gestational diabetes mellitus. (2) Methods: We searched databases of PubMed, Web of Science, Embase, China national knowledge infrastructure (CNKI), China science and technology journal database (VIP), and Wanfang Data for relevant articles. A systematic review and a meta-analysis were done to compare the distribution of Vitamin D receptor gene polymorphisms in gestational diabetes mellitus patients with those in controls using allelic, codominant, dominant, and recessive models. (3) Results: A total of eight eligible articles were included in the systematic review and of them, six articles were included in the meta-analysis. The vitamin D receptor gene rs7975232 polymorphism was associated with gestational diabetes mellitus under the allelic model (odds ratio = 1.28, 95% confidence interval 1.06–1.56), codominant model (CC vs. AA odds ratio = 1.97, 95% confidence interval 1.28–3.05), and recessive model (odds ratio = 1.83, 95% confidence interval 1.27–2.64) in the case of low heterogeneity. High heterogeneity existed in studies on the association of vitamin D receptor genes rs1544410, rs2228570, and rs731236 with gestational diabetes mellitus, and the most common sources of heterogeneity were the year of publication and matching. (4) Conclusion: Polymorphism of the vitamin D receptor gene rs7975232 may be associated with risk of developing gestational diabetes mellitus. Future studies should be designed to include standardized data collection and matching for important confounding factors such as body mass index, age, and race.
