摘要

背景:研究表明,维生素E作为一种抗氧化剂可以保护ω-3脂肪酸(FA)免受氧化。几项研究评估了ω-3脂肪酸和维生素E联合补充对肥胖指数的影响;然而,结果并不一致。本系统综述和荟萃分析旨在探讨ω-3脂肪酸加维生素E对肥胖指数的作用。方法:检索截至2022年2月的Cochrane图书馆、PubMed、Scopus、Embase和Web of Science数据库。在所有合格的研究中,选择了10篇文章。效应大小表示为加权平均差(WMD)和95%置信区间(CI)。采用固定效应模型进行荟萃分析。进行了亚组分析和发表偏倚评估。结果:纳入了10项符合条件的随机对照试验,共558名参与者。研究中ω-3脂肪酸和维生素E联合补充的平均剂量分别为1000-400毫克/天和400国际单位。干预时间从6到16周不等。ω-3和维生素E联合补充对体重(BW)(WMD=0.14kg;95%CI:0.13-0.42;p=0.297)和身体质量指数(BMI)(WMD=0.08,95%CI-0.01-1.16,p=0.073)没有显著影响。然而,亚组分析表明,如果干预持续8周以上,50岁以上的女性的BMI可能会增加。结论:补充ω-3脂肪酸和维生素E对体重和BMI没有显著影响;然而,应该注意的是,当补充持续时间>8周时,以及在2型糖尿病患者(年龄>50岁,BMI>25 kg/m2)中,干预的影响越来越大。

Can omega-3 fatty acids and vitamin E co-supplementation affect obesity indices?
Background: Studies have shown that vitamin E as an antioxidant protects omega-3 fatty acids (FAs) from oxidation. Several studies have evaluated the effect of omega-3 FAs and vitamin E co-supplementation on obesity indices; however, the results are inconsistent. The present systematic review and meta-analysis was conducted to address the role of omega-3 FAs plus vitamin E on obesity indices. Methods: Cochrane Library, PubMed, Scopus, Embase, and Web of Science databases were searched up to February 2022. Among all of the qualified studies, 10 articles were selected. The effect size was presented as weighted mean difference (WMD) and 95% confidence interval (CI). Fixed-effects model was employed to perform meta-analysis. Subgroup analysis and publication bias assessment were carried out. Results: Ten eligible randomized controlled trials comprising 558 participants were included. The average dose of omega-3 FAs and vitamin E co-supplementation in studies was 1000-4000 mg/day and 400 IU, respectively. Intervention duration varied from 6 to 16 weeks. There was no significant effect of omega-3 and vitamin E co-supplementation on body weight (BW) (WMD=0.14 kg; 95% CI: -0.13 to 0.42; p=0.297), and body mass index (BMI) (WMD=0.08, 95% CI: -0.01 to 0.16, p=0.073). However, subgroup analysis showed that it might increase BMI in women over 50 years and if the intervention lasted more than 8 weeks. Conclusion: There was no significant impact of combined omega-3 FAs and vitamin E supplementation on BW and BMI; however, it should be noted that the intervention has an increasing impact when supplementation duration was >8 weeks and in individuals with type 2 diabetes mellitus, >50 years old, and BMI>25.
