Effectiveness of health literacy and relaxing music on quality of sleep and risk for antenatal depression.

Background: Pregnant women experience increased sleep disturbances during the third trimester of their pregnancy, which may result in the development of psychological issues in the perinatal period. There is a dearth of interventional studies that combine health literacy and the provision of music for the benefit of pregnant women in South Asia.

Aim: To determine the effectiveness of a combination of Comprehensive Health literacy And Relaxing Music (CHARM) interventions on quality of sleep and risk for antenatal depression among women visiting antenatal outpatient departments of a tertiary hospital in South India.

Methods: A four-arm parallel-group randomized controlled trial was adopted; 128 low-risk primigravid women were recruited and randomly assigned to the four groups using block randomization. The interventions included relaxing music interventions, comprehensive health-literacy interventions, combinations of both as CHARM interventions, and standard antenatal care. All the interventions were provided for four weeks. The quality of sleep among pregnant women was assessed using the Pittsburgh Sleep Quality Index Scale at baseline and after four weeks of intervention. Women at risk of developing antenatal depression were screened using the Edinburgh Postnatal Depression Scale-Antenatal Version.

Results: Pregnant women who received CHARM interventions had significant improvement in quality of sleep when compared with other interventions ( =15.0, < .001, effect size 0.27). Also, 38 (29.6%) of the included pregnant women were at risk of developing antenatal depression, which was reduced to 21 (16.4%) following the intervention.

Conclusion: CHARM intervention could promote quality sleep and reduce the risk of developing antenatal depression, thereby improving perinatal mental health.
