The manuscript by Wang et al. contributes mightily to our limited understanding of grandparental care and children's mental health problems. As the authors document, despite the growing number of families worldwide where grandparents serve as the sole primary caregivers or reside with the children's parents to share caregiving responsibilities, and the growing number of studies examining associations between grandparental care and children's mental health-related outcomes, systematic reviews and meta-analyses integrating this literature are missing. There are meta-analyses on relations between grandparental care and such child outcomes as physical health, nutrition and obesity, education, and even resilience, but the extant literature on child outcomes has been limited to more qualitatively oriented reviews and has typically focused on child internalizing and externalizing problems. Thus, the current meta-analysis adds a novel and critically missing quantitative component to our broad understanding of the associations between grandparental care and children's problem behavior. In addition, beyond studies examining children's internalizing and externalizing outcomes, the authors also report on several studies (n = 7) that examine children's positive well-being and overall mental health. Overall, among the 38 studies deemed acceptable for review, the meta-analysis included findings from nearly 345,000 children, with a mean age of 10 years and slightly more female (51%) than male children.

关于“祖父母照顾和儿童心理健康：系统评价和荟萃分析”的评论

王等人的手稿。极大地加深了我们对祖父母护理和儿童心理健康问题的有限了解。正如作者所记录的那样，尽管全世界越来越多的家庭由祖父母作为唯一的主要照顾者或与孩子的父母住在一起分担照顾责任，并且越来越多的研究检验祖父母照顾与儿童心理健康相关结果之间的关系，缺少整合这些文献的系统评价和荟萃分析。对祖父母照顾与身体健康、营养和肥胖、教育甚至复原力等儿童结果之间的关系进行了荟萃分析，但现有的关于儿童结果的文献仅限于更加定性的评论，并且通常侧重于儿童内化并将问题外化。因此，当前的荟萃分析为我们对祖父母照顾与儿童问题行为之间关联的广泛理解添加了一个新颖且严重缺失的定量成分。此外，除了检查儿童内化和外化结果的研究之外，作者还报告了几项 检查儿童积极幸福感和整体心理健康的研究（ n = 7）。总体而言，在 38 项被认为可以接受审查的研究中，荟萃分析纳入了近 345,000 名儿童的研究结果，平均年龄为 10 岁，女性儿童 (51%) 略多于男性儿童。
