Abstract

INTRODUCTION

Diet is an important modifiable risk factor for many chronic diseases. Measurement of dietary intake usually relies on self-report, subject to multiple biases. There is a need to understand gender differences in the self-report of dietary intake and the implications of any differences in targeting nutrition interventions. Literature in this area is limited and it is currently unknown whether self-report dietary assessment methods are equally accurate for women and men. The aim of this systematic review is to determine whether there are differences by gender in reporting energy intake compared with a reference measure of total energy expenditure.

METHODS AND ANALYSIS

A comprehensive search of published original research studies will be performed in MEDLINE, Scopus, Web of Science, EMBASE, CINAHL and Cochrane library. Original research studies will be included if they were conducted in free-living/unhospitalised adults and included a measure for both women and men of (a) self-reported energy intake and (b) total energy expenditure by doubly labelled water. One author will conduct the electronic database searches, two authors will independently screen studies, conduct a quality appraisal of the included studies using standardised tools and extract data. If further information is needed, then study authors will be contacted. If appropriate, a random-effects meta-analysis will be conducted, with inverse probability weighting, to quantify differences in the mean difference in agreement between reported energy intake and measured energy expenditure between women and men, by self-report assessment method. Subgroup analyses will be conducted by participant factors, geographical factors and study quality.

ETHICS AND DISSEMINATION

All data used will be from published primary research studies or deidentified results provided at the discretion of any study authors that we contact. We will submit our findings to a peer-reviewed scientific journal and will disseminate results through presentations at international scientific conferences.

摘要

引言

饮食是许多慢性疾病的一个重要可改变风险因素。饮食摄入量的测量通常依赖自我报告，容易受到多种偏差的影响。有必要了解饮食摄入量自我报告中的性别差异以及这些差异对营养干预目标设定的影响。该领域的文献有限，目前尚不清楚自我报告的饮食评估方法对男性和女性是否同样准确。本系统评价的目的是确定与总能量消耗的参考测量相比，报告能量摄入量时是否存在性别差异。

方法与分析

将在MEDLINE、Scopus、科学网、EMBASE、护理学与健康领域数据库（CINAHL）和考科蓝图书馆全面检索已发表的原始研究。如果研究是在自由生活/未住院的成年人中进行的，并且包括对男性和女性的以下两项测量，则将纳入原始研究：（a）自我报告的能量摄入量；（b）通过双标水法测量的总能量消耗。将由一位作者进行电子数据库检索，两位作者将独立筛选研究，使用标准化工具对纳入研究进行质量评估并提取数据。如果需要更多信息，将联系研究作者。如果合适，将进行随机效应荟萃分析，并采用逆概率加权法，以通过自我报告评估方法量化女性和男性在报告能量摄入量与测量能量消耗之间的一致性平均差异中的差异。将按参与者因素、地理因素和研究质量进行亚组分析。
