摘要

目的和目的本研究的主要目的是对随机对照试验研究进行荟萃分析,以发现膳食纤维与肥胖及其相关症状之间的关系。方法于2024年1月9日在PubMed、b谷歌Scholar等数据库中进行电子检索,检索已发表的所有英文rct。制定了一项全面的搜索策略,以系统地识别关于膳食纤维和肥胖人群减肥的研究。b谷歌Scholar的搜索术语是“膳食纤维和肥胖”,PubMed的搜索术语是“(膳食纤维)和(肥胖)”。通过JBI检查表和强-周研究对研究进行定性评估。纳入研究绘制漏斗图、Hedges图和Galbraith图。结果在初始数据库中检索到4313篇文章,PubMed检索到3930篇,b谷歌Scholar检索到319篇,其他来源检索到64篇。在基于随机效应的模型下,荟萃分析发现膳食纤维与体重减轻之间存在显著相关性(d - 0.67; 95% CI - 1.04, - 0.31; P小于0.001),BMI与膳食纤维之间存在显著相关性(d - 0.37; 95% CI - 0.70, - 0.05; P = 0.02),体重减轻与膳食纤维之间存在非显著相关性(d - 2.36; 95% CI - 5.09, 0.37; P = 0.09)。结果表明,富含纤维的饮食对体重、身体质量指数和体脂率的降低有显著影响。结论:本荟萃分析在纳入的随机对照试验研究的基础上检验了膳食纤维与肥胖之间的显著关系。

Effect of dietary fiber on obese/overweight persons and its mechanism of action: A systematic and meta-analysis on randomized controlled trials

Aims and objectives

The main objective of the study is to conduct a meta-analysis of randomized controlled trial studies to find the relationship between dietary fiber and its association with obesity and related symptoms.

Methods

A literature search was performed by electronic means on 9 January 2024 in databases like PubMed and Google Scholar, reviewing all the RCTs published in English. A comprehensive search strategy was developed to methodically identify the research on dietary fiber and weight reduction in obese persons. The search terminology for Google Scholar was “dietary fiber and obesity”, and for PubMed was “(Dietary fiber) AND (obesity)”. The qualitative assessment of the study was evaluated by the JBI checklist and strong-to-week study. Funnel plot, Hedges’ g, and Galbraith plot were drawn for the included study.

Results

There were 4313 articles found in the initial database search, 3930 in PubMed, 319 in Google Scholar, and 64 entries from additional sources. A significant correlation between dietary fiber and weight loss (d −0.67; 95% CI −1.04, −0.31; P ˂ 0.001), between the BMI and dietary fiber (d −0.37; 95% CI −0.70, −0.05; P = 0.02), and a non-significant correlation between weight loss and dietary fiber (d −2.36; 95% CI −5.09, 0.37; P = 0.09) were found by meta-analytic pooling under a model based on random-effects. The result indicated a significant effect of the reduction of body weight, BMI, and body fat% after having a fiber-rich diet.

Conclusion

This meta-analysis examined a significant relationship between dietary fiber and obesity based on the included randomized controlled trial studies.

期刊介绍: Nutrition Clinique et Métabolisme is the journal of the French-speaking Society of Enteral and Parenteral Nutrition. Associating clinicians, biologists, pharmacists, and fundamentalists, the articles presented in the journal concern man and animals, and deal with organs and cells. The goal is a better understanding of the effects of artificial nutrition and human metabolism. Original articles, general reviews, update articles, technical notes and communications are published, as well as editorials and case reports.
