The impact of fatigue on the development of postpartum depression.
BACKGROUND
Previous research suggests early postpartum fatigue (PPF) plays a significant role in the development of postpartum depression (PPD). Predicting risk for PPD via early identification of PPF may provide opportunity for intervention.


OBJECTIVE
To replicate and extend previous studies concerning the impact of PPF on symptoms of PPD and to describe the relationships among PPF, PPD, and other variables using the theory of unpleasant symptoms.


METHODS
Correlational, longitudinal study.


METHODS
Participants' homes.


METHODS
Convenience sample of 42 community-dwelling women recruited before 36 weeks of pregnancy.


METHODS
PPF, depressive symptoms, and stress measured during prenatal weeks 36 to 38, and on Days 7, 14, and 28 after childbirth. Salivary cortisol was measured as a physiological marker of stress.


RESULTS
Significant correlations were obtained between PPF and symptoms of PPD on Days 7, 14, and 28, with Day 14 PPF levels predicting future development of PPD symptoms in 10 of 11 women. Perceived stress, but not cortisol, was also correlated with symptoms of PPD on Days 7, 14, and 28. Women with a history of depression had elevated depression scores compared to women without, but no variable was as effective at predicting PPD as PPF.


CONCLUSIONS
Fatigue by Day 14 postpartum was the most predictive variable for symptoms of PPD on Day 28 in this population.
