Exclusive breastfeeding and maternal postnatal anxiety contributed to infants' temperament issues at 6 months of age

This database includes the raw data linked with the paper “Exclusive breastfeeding and maternal postnatal anxiety contributed to infants' temperament issues at 6 months of age”. This publication is part of the longitudinal project “Measuring the outcomes of maternal COVID-19-related prenatal exposure (MOM-COPE)” research project. In this paper we report on longitudinal data on the effect of exclusive breastfeeding and postnatal maternal anxiety on infant’s temperament at six months. <strong>Procedures</strong> At childbirth and after 6 months, mothers reported on whether they were using exclusive breastfeeding, maternal milk from a bottle, formula or mixed feeding methods. At birth, the mothers also filled in the State-Trait Anxiety Inventory (Spielberger, 1983). After their infants reached 6 months (T1), they filled in the Infant Behavior Questionnaire- Revised short-form (Gartstein &amp; Rothbart, 2003). <strong>Findings in brief</strong> Exclusively breastfed infants exhibited higher levels of negative emotionality and lower regulatory capacity than the other group, with no significant differences for surgency. From the hierarchical regressions, a significant model was obtained for regulatory capacity. Significant main effects and an interaction effect emerged for exclusive breastfeeding and for postnatal maternal anxiety. The post hoc investigation revealed a significant negative association between postnatal maternal anxiety and infants' regulatory capacity in the exclusive breastfeeding group, compared with the other group.本数据库收录了与论文《纯母乳喂养与产妇产后焦虑对婴儿6月龄气质问题的影响》相关的原始研究数据。该研究成果隶属于纵向研究项目**‘孕产妇新冠相关产前暴露结局测量（MOM-COPE）’**。本研究报告了纯母乳喂养与产妇产后焦虑对婴儿6月龄气质影响的纵向观测数据。 **研究流程**：在分娩时及婴儿满6月龄时，产妇需报告自身采用的喂养方式，涵盖纯母乳喂养、奶瓶喂养母乳、配方奶喂养及混合喂养四种方式。分娩时，产妇还需填写《状态-特质焦虑量表（State-Trait Anxiety Inventory）》（Spielberger, 1983）。待婴儿年满6月龄（T1时间点）后，产妇需填写《婴儿行为问卷-修订简版（Infant Behavior Questionnaire- Revised short-form）》（Gartstein & Rothbart, 2003）。 **简要研究结果**：纯母乳喂养组婴儿的负性情绪水平显著高于其他喂养组，且调节能力更低；两组婴儿的外向性（Surgency）维度得分无显著差异。分层回归分析显示，婴儿调节能力维度存在显著预测模型。纯母乳喂养与产妇产后焦虑均存在显著主效应，且二者存在显著交互效应。事后检验结果表明，相较于其他喂养组，纯母乳喂养组中产妇产后焦虑与婴儿调节能力呈显著负相关。
