Abstract

INTRODUCTION

The Food Frequency Questionnaire is one of the most widely used tools for estimating nutritional intake in epidemiological studies. No study has been systematically performed to comprehensively explore Food Frequency Questionnaires designed, developed and validated specifically for the diabetic population (FFQs-DDV-DiaP). Therefore, a systematic review and meta-analysis will be carried out in order to identify and describe FFQs-DDV-DiaP; to examine their design, development, validity and reproducibility; as well as to estimate the overall degree of correlation and agreement; and to evaluate the factors that affect them.

METHODS AND ANALYSIS

A systematic literature review will be performed in PubMed/MEDLINE, Scopus and Web of Science to find potentially relevant studies. Original studies related to the design, development, as well as the assessment of the validity and reproducibility of FFQs-DDV-DiaP; reported in English or Romance languages will be selected. Independent reviewers will select studies, extract relevant data and assess FFQs-DDV-DiaP quality. Data will be pooled using the generic inverse-variance method with random-effects models and expressed as correlation coefficients or mean differences with 95% CIs to examine the global validity and reproducibility of FFQs-DDV-DiaP. Heterogeneity will be evaluated by the Cochran Q-statistic and quantified by the I statistic. Stratified analyses and random-effects meta-regressions will be performed to explore heterogeneity and whether any covariate influences the effect sizes. Finally, publication bias will be assessed through the Begg's and Egger's tests.

ETHICS AND DISSEMINATION

This systematic review and meta-analysis will not use confidential personal data. Therefore, the requirement of ethical approval or informed consent is not necessary. The results of this review will be disseminated only in peer-reviewed publications or at relevant scientific conferences.

摘要

简介

食物频率问卷是在流行病学研究中估计营养摄入量最常用的工具之一。目前尚未系统地进行研究，以全面探索专为糖尿病患者设计、开发和验证的食物频率问卷（FFQs-DDV-DiaP）。因此，将进行系统评价和荟萃分析，以确定和描述 FFQs-DDV-DiaP；检查它们的设计、开发、有效性和可重复性；以及估计总体相关性和一致性程度；并评估影响它们的因素。

方法和分析

将在 PubMed/MEDLINE、Scopus 和 Web of Science 中进行系统文献综述，以查找潜在相关研究。选择与 FFQs-DDV-DiaP 的设计、开发以及有效性和可重复性评估相关的原始研究，这些研究以英语或罗曼语报告。独立评审员将选择研究、提取相关数据并评估 FFQs-DDV-DiaP 的质量。使用通用倒数方差法和随机效应模型对数据进行汇总，并以相关系数或平均值差异（95%CI）表示，以检查 FFQs-DDV-DiaP 的总体有效性和可重复性。通过 Cochran Q 统计量评估异质性，并通过 I 统计量量化。将进行分层分析和随机效应荟萃回归，以探索异质性以及任何协变量是否影响效应大小。最后，通过 Begg's 和 Egger 检验评估发表偏倚。
