Association between blood loss at delivery and fatigue in the puerperium: a prospective longitudinal study

Abstract

Objective: The objective was to investigate the association between blood loss at delivery and physical and mental fatigue during the first 12 weeks postpartum. We also investigated the association between hemoglobin and postpartum fatigue.

Methods: We performed a single center prospective longitudinal study of healthy women with a singleton delivery. Women completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale at 3 and 7 d, 3, 8 and 12 weeks postpartum. The hemoglobin level was measured at inclusion (baseline).

Results: A total of 196 women with blood loss at delivery ranging from 100 to 2800 mL were included in the study. At 12 weeks follow-up the response rate was 92% (n = 181). We found a significant association between blood loss and scores of physical and mental fatigue within the first week postpartum. When adjusted for bleeding, hemoglobin measured at inclusion was not associated with fatigue at any given time point.

Conclusions: The amount of measured blood loss was significantly associated with increased physical and mental fatigue in the first week postpartum. When adjusted for bleeding, baseline hemoglobin was no longer associated with physical and mental fatigue.
