Summary
Relaxation interventions for lactating parents can increase human milk quantity and infant weight gain. These methods also help reduce parental stress and anxiety, supporting overall well-being.
Area of Science:
- Public Health
- Lactation Science
- Mental Health
Background:
- Human milk feeding is crucial for infant and maternal health, yet global outcomes fall short of recommended duration and exclusivity.
- Lactation is linked to maternal mental health, highlighting the need for supportive interventions.
Purpose of the Study:
- To evaluate the effectiveness of relaxation interventions in improving lactation outcomes and well-being among lactating individuals.
Main Methods:
- A systematic review and meta-analysis of randomized clinical trials were conducted.
- Searches were performed across multiple databases, including Embase, MEDLINE, and Cochrane Library.
- Data from 16 studies involving 1871 participants were synthesized.
Main Results:
- Relaxation interventions were associated with increased human milk quantity (SMD, 0.73) and enhanced infant weight gain (MD, 0.51 z score change).
- A significant reduction in parental stress (SMD, -0.49) and anxiety (SMD, -0.45) was observed.
- No association was found with changes in human milk protein content.
Conclusions:
- Relaxation interventions show promise for improving milk supply and infant growth in breastfeeding dyads.
- These interventions can be recommended to lactating parents aiming to enhance well-being and lactation outcomes.
