Poor sleep quality is related to old age among the general population, but few studies have focused on postpartum women of advanced maternal age. The present study aimed to describe and compare sleep quality between women younger or older than 35 years of age at 3 months postpartum, and to examine the related factors.


A cross-sectional survey was conducted with 160 postpartum women who had given birth at a teaching hospital in Taiwan. The participants were assigned to two groups according to age (≥35 years, n=80; and 20-34 years, n=80). Sleep quality was measured using the Pittsburgh Sleep Quality Index with a cut-off score of 5.


The prevalence of poor sleep quality at 3 months postpartum was higher in older mothers (61.6%) than in younger mothers (38.4%, p<0.01). Multiple logistic regression revealed that poor sleep quality was positively correlated with the severity of postpartum physical symptoms, lack of exercise, and room-sharing with infants. After adjustment for those variables, older mothers were three times more likely to have poor sleep quality than younger mothers (odds ratio=3.08; 95% confidence interval 1.52-6.23).


Health care providers should pay attention to sleep problems among postpartum women, especially mothers of advanced maternal age. In particular, health care providers should evaluate sleep quality among postpartum women, instruct them not to share the bed with their infants at night, perform exercise, and manage their postpartum physical symptoms to improve the sleep quality.
