Bidirectional relationship between physical health symptoms and depressive symptoms in the pre- and postpartum period.

OBJECTIVE

To test the bidirectional relationships between physical health symptoms (PHS) and depressive symptoms (DS) as well as between the intensity of 'any pain' and DS in the pre- and postpartum period METHOD: Women (N = 615) completed the Edinburgh Postnatal Depression Scale, the Patients Health Questionnaire-15, and numerical pain rating scales when they were between 32 and 37 weeks of gestation, and subsequently one, three, and six months postpartum. We conducted two random intercept cross-lagged panel models (RI-CLPM) RESULTS: Both models presented excellent fits. The relationship between PHS and DS was bidirectional across all the data waves (χ(9) = 6.610, p = .678, CFI = 1, TLI = 1, RMSEA = 0). The magnitude of the standardized cross-lagged regression coefficient was relatively similar from DS to PHS (raging between 0.081 and 0.171); and from PHS to DS (raging between 0.121 and 0.138). The relationship between 'any pain' intensity and DS was also bidirectional, but only during the postnatal period (χ(9) =11.765, p = .227, CFI = 0.99, TLI = 0.98, RMSEA = 0.022). The magnitude of the standardized cross-lagged regression coefficient was higher from DS to 'any pain' intensity (raging between 0.214 and 0.216); than from 'any pain' intensity to DS (raging between 0.092 and 0.097).

CONCLUSIONS

Concurrently intervening over physical and mental health symptoms could promote women's perinatal health.
