In the current study, we aimed to review the evidence from twin and family-based studies that have assessed the familial similarity in intakes of energy and macronutrients among various parent-child pairs. The online literature databases, including Web of Science, PubMed, and Scopus, were searched up to December 2022 to find potentially eligible studies. We converted Pearson's, Spearman's, or intra-class correlation coefficients to z's using Fisher's z transformation to obtain approximate normality and then calculated a mean and standard error (SE) of transformed correlation weighted by the sample sizes in the studies. We reported pooled and 95% CI as our final results in five groups, including parent-child, mother-daughter, mother-son, father-daughter, and father-son. Twenty-one eligible studies were included in this meta-analysis, in which the sample size ranged from 33 and 4310. Our analysis showed that family resemblance in the intake of energy and macronutrients in various parent-offspring pairs was weak to moderate which could be different based on family pairs, nutrients, and studies. The highest similarity in dietary intakes was observed among the mother-daughter pair, which was for carbohydrate and protein intake, respectively. The lowest correlations in dietary intakes were found between mother-son or father-son pairs. Our meta-analysis suggested that family similarity for intakes of energy and macronutrients was not strong in parent-child pairs. The highest correlation in dietary intake was mostly found in mother-daughter pairs. The weak similarities in dietary intake among parent-child pairs indicate the noticeable effect of the environment outside the family on individuals' dietary choices.
在本研究中，我们旨在回顾来自双胞胎和基于家庭的研究证据，这些研究评估了不同亲子对之间能量和宏量营养素摄入量的家族相似性。检索了包括科学网、PubMed和Scopus在内的在线文献数据库，截至2022年12月，以寻找可能符合条件的研究。我们使用Fisher z变换将Pearson相关系数、Spearman相关系数或组内相关系数转换为z值，以获得近似正态性，然后计算研究中按样本量加权的转换后相关性的均值和标准误（SE）。我们报告了五组（包括亲子、母女、母子、父女和父子）的合并结果和95%置信区间作为最终结果。本荟萃分析纳入了21项符合条件的研究，样本量从33到4310不等。我们的分析表明，不同亲子对之间能量和宏量营养素摄入量的家族相似性较弱至中等，这可能因家庭对、营养素和研究而异。在母女对中观察到膳食摄入量的最高相似性，分别是碳水化合物和蛋白质摄入量。膳食摄入量的最低相关性出现在母子对或父子对之间。我们的荟萃分析表明，亲子对之间能量和宏量营养素摄入量的家族相似性不强。膳食摄入量的最高相关性大多出现在母女对中。亲子对之间膳食摄入量的微弱相似性表明家庭外部环境对个体饮食选择有显著影响。
