Effectiveness of preventive parental education delivered from pregnancy to 1 month postpartum for improving infant sleep and parental sleep and depression: a systematic review protocol.

Objective: This review aims to evaluate the effectiveness of preventive parental education on infant sleep problems, delivered from pregnancy to 1 month postpartum, on infant sleep, postpartum parental sleep, and depression.

Introduction: Infant sleep problems are likely to persist into childhood if not treated and are associated with difficulties in later development. Parents of children with sleep problems had lower sleep quality and emotional regulation than those without sleep problems. Chronic sleep deprivation and fragmentation increases the risk of maternal depression. Therefore, preventive parental education regarding infant sleep problems can improve the long-term well-being of both children and their parents.

Inclusion criteria: Experimental and quasi-experimental study designs, including preventive parental education about infant sleep problems delivered from pregnancy to 1 month postpartum, will be considered. The outcomes will be infants' sleep, postpartum parental sleep, and parental depression.

Methods: MEDLINE (Ovid), CINAHL (EBSCOhost), PsycINFO (Ovid), the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi (Japan Medical Abstracts Society) will be searched without restrictions on language or date of publication. Eligible studies will be critically appraised, and data will be extracted by 2 independent reviewers using the JBI methodology. The studies will be pooled for statistical meta-analysis. Where statistical pooling is not possible, the findings will be presented in narrative format. We will use the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to assess the certainty in the quality of evidence.
