Non-pharmacological Interventions for Improving Sleep Quality During Pregnancy: A Systematic Review and Meta-Analysis

The Effect of Sleep Enhancement Educational Program on Maternal Sleep Quality for Nulliparous Pregnant Women: A Randomized-Controlled Trial

BACKGROUND

Pregnancy is a critical period during which women usually do not prefer taking medication. Therefore, non-pharmacological and safe methods are needed to improve sleep quality during pregnancy. This study aims to identify whether an educational program on sleep enhancement for pregnant women has any effect on maternal sleep quality.

METHOD

This was a randomized-controlled trial. Pregnant women (N = 181) were divided into two groups, an intervention group (n = 90) and a control group (n = 91). A two-session educational program for the enhancement of sleep quality was provided to the intervention group, whereas solely the routine practices of the hospital were put in place for the control group.

RESULTS

The intervention group had a significantly lower mean Pittsburgh Sleep Quality Index score, and accordingly, better sleep quality than the control group. Participation in the education program was significantly related to sleep quality and accounted for 6% of the total variance in sleep quality (R2 = 0.055) (p < 0.001).

CONCLUSION

It was concluded that the educational program on sleep enhancement implemented to improve the sleep quality of pregnant women enhanced maternal sleep quality.

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 (F(3,124) =15.0, P < .001, effect size η p2= 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.

Effects of Two Physical Activity Interventions on Sleep and Sedentary Time in Pregnant Women

Pregnancy is often associated with poor sleep and high sedentary time (SED). We investigated the effect of physical activity (PA) interventions on sleep and SED in pregnant women. A secondary analysis of a randomized controlled trial (n = 219) explored the effect of structured supervised exercise training (EXE) or motivational counseling on PA (MOT) compared to standard prenatal care (CON) on sleep and SED during pregnancy. Three times during pregnancy, sleep was determined by the Pittsburgh Sleep Quality Index (PSQI) and SED by the Pregnancy Physical Activity Questionnaire (PPAQ). Also, a wrist-worn consumer activity tracker measured sleep and SED continuously. Data from the activity tracker confirmed that sleep time decreases, and SED increases by approx. 30 and 24 min/day, respectively, from baseline (maximum gestational age (GA) week 15) to delivery. Compared to CON, the global PSQI score was better for EXE in GA week 28 (-0.8 [-1.5; -0.1], p = 0.031) and for both EXE and MOT in GA week 34 (-1 [-2; -0.5], p = 0.002; -1 [-2; -0.1], p = 0.026). In GA week 28, SED (h/day) from PPAQ was lower in EXE compared to both CON and MOT (-0.69 [-1; -0.0], p = 0.049; -0.6 [-1.0; -0.02], p = 0.042). In conclusion, PA interventions during pregnancy improved sleep quality and reduced SED.
