The most important predictor of poor sleep quality in postpartum women was postpartum physical symptoms
(explaining 13.6% of total variance). Poor sleep quality was also predicted by the frequency of nighttime awakening
(explaining 7.5% of total variance) and co-sleeper disturbances (explaining 3.1% of total variance). Social
support was not a significant predictor of sleep quality in our study, but marital satisfaction was, in contrast to
previous reports that social support improved postpartum women’s sleep (Huang et al., 2004; Teng et al., 2007) and
marital satisfaction did not (Insana et al., 2011.)
