In studies investigating predictors of breastfeeding behaviors, it is not uncommon for researchers to adjust for participants' having been breastfed as an infant. This assumes an intergenerational effect of breastfeeding continuity. Our aim was to investigate the veracity of that assumption. Specifically, we sought to summarize and evaluate evidence of associations between breastfeeding in one generation and breastfeeding intentions and behaviors in the second generation.
A systematic search of psychological, nursing, and medical databases was conducted for studies examining "having been breastfed" as a factor in breastfeeding intention, initiation, or duration. Quality indicators were assessed and limitations reported. Effects were explored according to outcomes of intention, initiation, and duration.
Fifteen papers were found to be eligible for the review. Having been breastfed as an infant was consistently correlated with breastfeeding intention, initiation, and duration. Effect sizes differed depending on methodology. Men's infant-feeding status was also related to later intentions to support or encourage a partner to breastfeed.
Robust evidence for intergenerational breastfeeding continuity is present; however, mechanisms that explain this association were not considered in the studies reviewed and would best be explored within longitudinal cohort studies.
在调查母乳喂养行为预测因素的研究中，研究人员将参与者婴儿时期是否接受母乳喂养作为一个调整因素的情况并不少见。这假定了母乳喂养连续性的代际效应。我们的目的是调查这一假设的真实性。具体而言，我们试图总结和评估一代母乳喂养与二代母乳喂养意愿和行为之间关联的证据。
对心理学、护理学和医学数据库进行系统检索，以查找将“婴儿时期接受母乳喂养”作为母乳喂养意愿、开始或持续时间因素的研究。评估质量指标并报告局限性。根据意愿、开始和持续时间的结果探讨效应。
发现15篇论文符合综述要求。婴儿时期接受母乳喂养与母乳喂养意愿、开始和持续时间始终相关。效应大小因方法而异。男性婴儿喂养状况也与后来支持或鼓励伴侣母乳喂养的意愿有关。
存在代际母乳喂养连续性的有力证据；然而，在所审查的研究中未考虑解释这种关联的机制，最好在纵向队列研究中进行探索。
