Insights
Prenatal anxiety may impact infant feeding intentions and exclusivity, but evidence is limited. More research is needed to fully understand the effects of maternal anxiety on infant feeding practices.
Area of Science:
- Maternal-fetal medicine
- Developmental psychology
- Public health nutrition
Background:
- Prenatal anxiety is a significant concern impacting maternal and infant well-being.
- Infant feeding practices are crucial for child development and health.
- The specific link between maternal anxiety during pregnancy and infant feeding outcomes requires further elucidation.
Purpose of the Study:
- To systematically review and synthesize existing research on the relationship between prenatal anxiety and infant feeding outcomes.
- To identify gaps in the current literature regarding this association.
- To inform future research and clinical practice.
Main Methods:
- A comprehensive literature search was conducted across multiple electronic databases.
- Hand searches of relevant journals and reference lists were performed to identify additional studies.
- Studies were included if they reported on infant feeding outcomes and anxiety during pregnancy; data extraction and quality assessment were performed by two independent reviewers.
Main Results:
- No significant associations were found between prenatal anxiety and breastfeeding initiation or overall breastfeeding quantity.
- A negative relationship was observed between high levels of prenatal anxiety and both breastfeeding intention and breastfeeding exclusivity.
- The review included only 6 eligible studies out of 99 identified, highlighting a limited evidence base.
Conclusions:
- Current evidence is insufficient to definitively clarify the relationship between prenatal anxiety and infant feeding outcomes.
- Limitations including small sample sizes, lack of statistical power, and heterogeneous measures hinder comparability of findings.
- Further high-quality research is warranted to establish a clearer understanding of how prenatal anxiety influences infant feeding practices.
Abstract:
Prenatal anxiety may negatively affect infant health in multiple domains, including infant feeding. However, the relationship between prenatal anxiety and infant feeding is not well understood. Given the benefits of recommended infant feeding practices, clarifying this relationship is important. This review was conducted to examine the relationship between prenatal anxiety and infant feeding outcomes. Electronic searches were performed in relevant databases. A hand search of selected journals and reference lists of included articles was then conducted. All studies were considered that provided information related to infant feeding outcomes and anxiety during pregnancy. Quality assessment and data extraction were conducted by 2 reviewers; 99 studies were identified, of which 6 were eligible. No associations were found between prenatal anxiety and breastfeeding initiation or breastfeeding in any quantity. However, relationships between high levels of prenatal anxiety and a reduction in both breastfeeding intention and breastfeeding exclusivity were identified. The review was limited by the small number of studies included. Sample sizes lacking power and heterogeneous measures and definitions all significantly affected the comparability of findings. It is concluded that there is insufficient evidence to clarify the relationship between prenatal anxiety and infant feeding outcomes.
