Effect on the practice of the kangaroo method on the formation and strengthening of the mother-baby bond: a systematic review

Abstract Objectives: a systematic review study with the objective of estimating the effect on the practice of the kangaroo method (KM) on the formation and strengthening of the mother-baby bond (MBB). Methods: independent searches were performed in three international databases in the United States National Library of Medicine - PubMed, Scientific Electronic Library Online - Scielo and Web of Science databases. Searches were made without limit on languages and year of publication. Results: the final selection consisted of 27 studies, 14 of a quantitative nature (nine clinical trials and five observational) and 13 qualitative. All qualitative articles and most quantitative ones (n=10) indicated the practice of the KM as favorable to the formation and strengthening of the MBB. Other quantitative studies did not show statistically significant differences in the comparisons made between groups. None of the 27 studies found unfavorable effects resulting from the practice of KM on the MBB. Conclusion: the results suggest that the KM favors the formation and strengthening of the MBB regardless of the weight and gestational age of the newborns or the place of measurement (hospital or residence). Thus, encouraging the execution of this biopsychosocial intervention of qualified and humanized care is recommended for the promotion of children’s health.摘要 研究目的：本项系统综述旨在评估袋鼠式护理法（Kangaroo Method, KM）对母婴联结（Mother-Baby Bond, MBB）的形成与强化所产生的效应。 研究方法：于美国国家医学图书馆（United States National Library of Medicine）旗下PubMed、科学电子图书馆在线（Scientific Electronic Library Online, SciELO）及Web of Science这3个国际数据库中开展独立检索，本次检索未限定语言与发表年份。 研究结果：最终纳入27项相关研究，其中14项为定量研究（含9项临床试验与5项观察性研究），剩余13项为定性研究。所有定性研究与多数定量研究（n=10）均显示，实施袋鼠式护理法有利于母婴联结的形成与强化。其余定量研究在组间比较中未发现统计学显著性差异。27项研究均未发现实施袋鼠式护理法会对母婴联结造成不良影响。 研究结论：本研究结果提示，无论新生儿体重、胎龄或测量场所（医院或居家）如何，袋鼠式护理法均能促进母婴联结的形成与强化。据此，推荐推广此项兼具规范资质与人文关怀的生物-心理-社会干预照护措施，以促进儿童健康。
