Abstract summary 

Aging, female sex, and urbanization increase the risk of sleep impairment. Sleep in urban-dwelling elderly African women has been sparsely studied. We studied the characteristics and correlates of sleep quality and habitual sleep duration in a primary care population of urban-living Nigerian women.Sleep quality and sleep duration over the previous 1 month were estimated using the Pittsburgh Sleep Quality Index (PSQI). Excessive daytime sleepiness, risk of obstructive sleep apnea (OSA), and depressive symptoms were also assessed.Of the 428 subjects included, 117 (27.3%) were poor sleepers endorsing PSQI scores >5, whereas 126 (29.4%) slept <7 hours. The poor sleepers were more likely to be obese (P = .022), to have a high risk for OSA (P = .013), and to have clinically significant depressive symptoms (P = .001) compared with the good sleepers. Habitual sleep duration of <7 hours was associated with past oral contraceptive use (P = .025) and a trend toward a higher likelihood of high risk for OSA (P = .05) and coffee consumption (P = .05). On regression, the odds of high risk for OSA were higher with poor sleep quality and sleep duration <7 hours, respectively, whereas the odds of coffee consumption were higher with sleep duration <7 hours.Poor sleep quality and inadequate sleep are common in our population of elderly women. High risk for OSA independently predicts poor sleep quality and, along with report of coffee consumption, independently predicts habitual sleep duration of <7 hours.
