  • 纳入11项RCT研究(每项研究纳入57-1488名健康成年受试者,干预持续时间1-12个月),总结个性化营养建议对营养摄入、食物摄入及饮食模式的影响;
  • 在8项研究中,与一般性的营养建议相比,个性化营养建议对受试者的至少一项饮食摄入相关指标有着更大程度的改善作用;
  • 最常用的饮食摄入相关指标是蔬菜与水果的摄入变化,少数研究关注了总体饮食模式(健康饮食评分及地中海饮食评分)。

Abstract:收起
Personalized nutrition (PN) behavior-change interventions are being used increasingly in attempts to improve dietary intake; however, the impact of PN advice on improvements in dietary intake has not been reviewed systematically. The aim of this systematic review was to evaluate the effect of PN advice on changes in dietary intake compared with generalized advice in healthy adults. Three databases (EMBASE, PubMed, and CINAHL) were searched between 2009 and 2020 for randomized controlled trials (RCTs) that tested the effect of PN and tailored advice based on diet, phenotype, or genetic information. The Evidence Analysis Library Quality Criteria checklist was used to conduct a risk-of-bias assessment. Information on intervention design and changes in nutrients, foods, and dietary patterns was extracted from the 11 studies meeting the inclusion criteria. Studies were conducted in the United States, Canada, or Europe; reported outcomes on 57 to 1488 participants; and varied in follow-up duration from 1 to 12 mo. Five studies incorporated behavior-change techniques. The risk of bias for included studies was low. Overall, the available evidence suggests that dietary intake is improved to a greater extent in participants randomly assigned to receive PN advice compared with generalized dietary advice. Additional well-designed PN RCTs are needed that incorporate behavior-change techniques, a broader range of dietary outcomes, and comparisons between personalization based on dietary, biological, and/or lifestyle information.
