尽管一些随机临床试验已经测试了产前膳食补充剂对非药物管理的妊娠期糖尿病患者(GDM)的血糖和血脂水平的影响,在上下文中缺乏严格的荟萃分析纲要。因此,本研究旨在弥补这一证据缺口.
■从PubMed搜索中检索到的合格试验,Embase,和Scopus数据库使用修订的Cochrane偏倚风险工具对随机试验(RoB2)进行评估.使用血浆血糖和脂质标志物的随机效应荟萃分析模型估计膳食补充剂和安慰剂之间的加权平均差异(WMD)。随后进行了Meta回归分析,用于效果修饰剂的鉴定。统计显著性估计发生在p<0.05(95%置信区间)。
■本综述纳入了19项试验(主要是伊朗试验,主要是低偏倚风险)>8000例GDM患者。Meta分析显示,饮食补充对空腹血糖的有利影响(WMD:-5.42mg/dL,p<0.001),稳态模型评估指标-胰岛素抵抗(HOMA-IR;WMD:-1.02,p<0.001),定量胰岛素敏感性检查指数(WMD:0.01,p<0.001),总胆固醇(TC;WMD:-7.70mg/dL,p=0.006),甘油三酯(WMD:-10.23mg/dL,p=0.0083),TC/高密度脂蛋白(WMD:-0.31mg/dL,p<0.001),低密度脂蛋白(WMD:-5.79mg/dL;p<0.001)和极低密度脂蛋白(WMD:-5.67mg/dL,p<0.001)水平。然而,HOMA-β-细胞功能没有增加(WMD:-17.91,p<0.001)。基线母亲年龄(β=0.28,p=0.014)和GDM诊断标准(β=0.90,p=0.012)是HOMA-IR和体重指数(BMI)(β=6.07,p=0.022)的效应调节剂,补充类型(单独与联合)(β=14.99,p=0.006)是甘油三酯水平的效应调节剂。
■总之,在非药物治疗的GDM患者中,产前膳食补充剂实现了对血浆血糖和血脂的控制.母亲年龄和GDM诊断标准调节HOMA-IR水平。BMI和补充剂型调节甘油三酯水平。

UNASSIGNED: Although several randomized clinical trials have tested the effect of prenatal dietary supplements on plasma glucose and lipid levels in non-pharmacologically managed gestational
diabetes mellitus patients (GDM), a rigorous meta-analytic compendium lacks in the context. Therefore, this study aims to address this evidence gap.
UNASSIGNED: Eligible trials retrieved from searches in the PubMed, Embase, and Scopus databases were appraised using the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2). The weighted mean differences (WMD) between dietary supplements and placebo were estimated using random-effect meta-analysis models for plasma glycemic and lipid markers. Meta-regression analysis ensued for effect modifier identification. The statistical significance estimation happened at p < 0.05 (95% confidence interval).
UNASSIGNED: This
review included 19 trials (mostly Iranian and of low risk of bias primarily) of > 8000 GDM patients. Meta-analysis showed favorable effects of dietary supplementation on fasting plasma glucose (WMD: -5.42 mg/dL, p < 0.001), homeostasis model assessment indexes- insulin resistance (HOMA-IR; WMD: -1.02, p < 0.001), quantitative insulin sensitivity check index (WMD: 0.01, p < 0.001), total cholesterol (TC; WMD: -7.70 mg/dL, p = 0.006),
triglycerides (WMD: -10.23 mg/dL, p = 0.0083), TC/high-density lipoprotein (WMD: -0.31 mg/dL, p < 0.001), low-density lipoprotein (WMD: -5.79 mg/dL; p < 0.001) and very-low-density lipoprotein (WMD: -5.67 mg/dL, p < 0.001) levels. However, the HOMA- ß-cell function didn\'t increase (WMD: -17.91, p < 0.001). Baseline maternal age (ß = 0.28, p = 0.014) and GDM diagnostic criteria (ß = 0.90, p = 0.012) were effect moderators of HOMA-IR and body mass index (
BMI) (ß = 6.07, p = 0.022) and supplement type (solo versus combined) (ß = 14.99, p = 0.006) were effect moderators of triglyceride levels.
UNASSIGNED: Altogether, antenatal dietary supplements achieved control over plasma glycemic and lipid profiles in non-pharmacologically treated GDM patients. Maternal age and GDM diagnostic criteria moderated HOMA-IR levels.
BMI and supplement-type moderated triglyceride levels.
