Oxytocin (OT) plays a pivotal role in early parent-child relationship formation and bonding that is critical for the social, cognitive, and emotional development of the child. Therefore, this systematic review aims to consolidate all available evidence regarding the associations of parental OT concentration levels with parenting behavior and bonding within the past 20 years. A systematic search was conducted in five databases from 2002 to May 2022, and 33 studies were finalized and included. Due to the heterogeneity of the data, findings were presented narratively based on the type of OT and parenting outcomes. Current evidence strongly suggests that parental OT levels are positively related to parental touch and parental gaze and affect synchrony and observer-coded parent-infant bonding. No gender difference in OT levels was observed between fathers and mothers, but OT strengthens affectionate parenting in mothers and stimulatory parenting in fathers. Child OT levels were also positively associated with parental OT levels. Family and healthcare providers could encourage more positive touch and interactive play between parent and child to strengthen parent-child relationships.
催产素（OT）在早期亲子关系的形成和联结中起着关键作用，这对儿童的社会、认知和情感发展至关重要。因此，本系统综述旨在整合过去20年中所有关于父母催产素浓度水平与养育行为及联结之间关联的现有证据。2002年至2022年5月期间在五个数据库中进行了系统检索，最终确定并纳入了33项研究。由于数据的异质性，根据催产素类型和养育结果以叙述方式呈现研究结果。目前的证据有力地表明，父母的催产素水平与父母的触摸和目光接触呈正相关，并影响同步性和观察者编码的亲子联结。未观察到父亲和母亲在催产素水平上的性别差异，但催产素增强了母亲的温情养育和父亲的激励性养育。儿童的催产素水平也与父母的催产素水平呈正相关。家庭和医疗保健提供者可以鼓励父母与孩子之间更多积极的触摸和互动游戏，以加强亲子关系。
