There is a strong societal belief that parents are role models for their child's dietary behaviours in early life that may persist throughout the life course. Evidence has shown inconclusive dietary resemblance in parent-child (PC) pairs. This systematic review and meta-analysis aimed to examine dietary resemblance between parent and children.
We systematically searched for studies on PC dietary resemblance, via six electronic databases (PubMed, Ovid MEDLINE, Embase, APA PsycNet, CINAHL, and Web of Science) and other grey sources of literature between 1980 and 2020. We performed quality effect meta-analysis model on transformed correlation coefficients (z) to examine the resemblance in dietary intakes including nutrient intakes, food group intakes and whole diet. Finally, the Fisher's transformed coefficient (z) was used for meta-regression analysis to identify potential moderators. Heterogeneity and inconsistency were examined using the Q and I statistic. The study is registered on PROSPERO, CRD42019150741.
A total of 61 studies met the inclusion criteria for systematic review, 45 were included in the meta-analysis. Pooled analyses showed weak to moderate PC dietary intake associations for energy: (r: 0.19; 95% CI: 0.16, 0.22), fat (% energy): (r: 0.23; 95% CI: 0.16, 0.29), protein (% energy): (r: 0.24; 95% CI: 0.20, 0.27), carbohydrate (% energy): (r: 0.24; 95% CI: 0.19, 0.29), fruits and vegetable (g/d): (r: 0.28; 95% CI: 0.25, 0.32), confectionary food (g/d): (r: 0.20; 95% CI: 0.17, 0.23), and whole diet (r: 0.35; 95% CI: 0.28, 0.42). Dietary intakes associations by study characteristics, including population, study year, dietary assessment method, person reporting dietary intake, quality of the study, and study design were highly variable, but associations were similar between PC pairs.
The resemblance among parent-child pairs was weak to moderate for most aspects of dietary intakes. These findings challenge the social myth that parental dietary intake behaviour shapes their child's dietary intake.

社会普遍认为，父母是孩子早年饮食行为的榜样，这种影响可能会贯穿一生。有证据表明亲子（PC）对之间的饮食相似性尚无定论。本系统评价和荟萃分析旨在研究父母与子女之间的饮食相似性。
我们通过六个电子数据库（PubMed、Ovid MEDLINE、Embase、APA PsycNet、CINAHL和Web of Science）以及其他灰色文献来源，系统检索了1980年至2020年间关于PC饮食相似性的研究。我们对转换后的相关系数（z）进行了质量效应荟萃分析模型，以检验包括营养素摄入量、食物组摄入量和整体饮食在内的饮食摄入量的相似性。最后，使用费舍尔转换系数（z）进行荟萃回归分析，以确定潜在的调节因素。使用Q和I统计量检验异质性和不一致性。该研究已在PROSPERO注册，注册号为CRD42019150741。
共有61项研究符合系统评价的纳入标准，45项纳入荟萃分析。汇总分析显示，亲子饮食摄入量在能量方面的关联较弱至中等：（r：0.19；95%CI：0.16，0.22），脂肪（能量百分比）：（r：0.23；95%CI：0.16，0.29），蛋白质（能量百分比）：（r：0.24；95%CI：0.20，0.27），碳水化合物（能量百分比）：（r：0.24；95%CI：0.19，0.29），水果和蔬菜（克/天）：（r：0.28；95%CI：0.25，0.32），糖果类食物（克/天）：（r：0.20；95%CI：0.17，0.23），以及整体饮食（r：0.35；95%CI：0.28，0.42）。按研究特征（包括人群、研究年份、饮食评估方法、报告饮食摄入量的人、研究质量和研究设计）划分的饮食摄入量关联差异很大，但PC对之间的关联相似。
在饮食摄入量的大多数方面，亲子对之间的相似性较弱至中等。这些发现挑战了父母的饮食摄入行为塑造孩子饮食摄入的社会神话。
