Abstract

Background

The Mediterranean diet has been shown to be effective in improving health outcomes and for weight loss. Adherence and retention in dietary interventions are critical to ensure the benefits of the exposure. No studies to date have assessed the role of gender in understanding participants who remain engaged and adhere to Mediterranean diet interventions.

Aims

This study aimed to explore gender differences in recruitment, adherence, and retention for Mediterranean diet interventions and whether these were associated with differences in weight-loss outcomes.

Methods

A systematic search was completed in EMBASE, Medline, Cochrane, and clinicaltrials.gov from inception to March 2023. A meta-analysis of studies reporting retention by gender was completed using odds ratios comparing female to male dropout numbers. A second meta-analysis was completed for adherence comparing standardized mean difference of Mediterranean diet scores stratified by gender. Newcastle Ottawa score was used to assess risk of bias.

Results

A total of 70 articles were included in the systematic review with six articles included in the adherence meta-analysis and nine in the dropout meta-analysis. No statistically significant difference was shown for adherence or retention by gender. Weight-loss outcomes were inconsistent.

Conclusions

The results of the study suggest a higher adherence and lower dropout for women although these results were not statistically significant. Future studies of Mediterranean diet interventions should include adherence, retention, and weight-loss data stratified by gender to allow further investigation of this relationship.

在以减肥为目的的地中海饮食干预中,坚持和保持的性别差异:系统回顾和荟萃分析。
背景:地中海饮食已被证明能有效改善健康状况和减轻体重。坚持和保持饮食干预对于确保接触地中海饮食的益处至关重要。目的:本研究旨在探讨地中海饮食干预在招募、坚持和保持方面的性别差异,以及这些差异是否与减肥结果的差异有关:方法:从开始到 2023 年 3 月,在 EMBASE、Medline、Cochrane 和 clinicaltrials.gov 中进行了系统检索。利用比较女性和男性辍学人数的几率比,完成了按性别对报告保留率的研究进行的荟萃分析。第二项荟萃分析针对依从性完成,比较了按性别分层的地中海饮食评分的标准化平均差。纽卡斯尔-渥太华评分用于评估偏倚风险:共有 70 篇文章被纳入系统综述,其中 6 篇文章被纳入依从性荟萃分析,9 篇文章被纳入辍学荟萃分析。从统计学角度看,不同性别的坚持率或保持率没有明显差异。减肥结果不一致:研究结果表明,女性的坚持率较高,辍学率较低,但这些结果在统计学上并不显著。未来的地中海饮食干预研究应包括按性别分层的坚持率、保持率和体重减轻数据,以便进一步调查这种关系。

期刊介绍: Obesity Reviews is a monthly journal publishing reviews on all disciplines related to obesity and its comorbidities. This includes basic and behavioral sciences, clinical treatment and outcomes, epidemiology, prevention and public health. The journal should, therefore, appeal to all professionals with an interest in obesity and its comorbidities. Review types may include systematic narrative reviews, quantitative meta-analyses and narrative reviews but all must offer new insights, critical or novel perspectives that will enhance the state of knowledge in the field. The editorial policy is to publish high quality peer-reviewed manuscripts that provide needed new insight into all aspects of obesity and its related comorbidities while minimizing the period between submission and publication.
