Religiosity, spirituality, and depressive symptoms in pregnant women

Objective: Depression during pregnancy has potential repercussions for both women and infants. Religious and spiritual characteristics may be associated with fewer depressive symptoms. This study examines the association between religiosity/spirituality and depressive symptoms in pregnant women. Method: Pregnant women in three southern obstetrics practices were included in a cross sectional study evaluating religiosity, spirituality, and depressive symptoms. Symptoms of depression were measured using the Edinburgh Postnatal Depression Scale (EPDS). The depression outcome was measured in two ways: the EPDS score as a continuous outcome, and a score at or above the recommended EPDS cutoff (> 14). A wide array of potential confounders was addressed. Special attention was given to the interplay between religiosity/spirituality, social support, and depressive symptoms. Results: The mean EPDS score was 9.8 out of a maximum possible score of 30. Twenty-eight women (8.1%) scored above the recommended EPDS cutoff score. Overall religiosity/spirituality was significantly associated with fewer depressive symptoms when controlling for significant covariates, but there was a significant interaction such that the association became weaker as social support increased. Social support did not appear to be an important mediator (intermediate step) in the pathway between religiosity/spirituality and depressive symptoms. Conclusions: Religiosity and spirituality may help protect from depressive symptoms when social support is lacking. Longitudinal research is needed to assess the directionality of the observed relationships.
