Context: Researchers have associated insomnia with many disorders, making insomnia a serious public health issue in China. Sleep quality in older adults isn't well characterized in China.
Objective: The study intended to explore the sleep quality and subjective duration of sleep in a community-dwelling older population in China and identify potential risk factors for poor sleep.
Design: The research team performed a cross-sectional survey using the convenience sampling method.
Setting: The study took place in a community in Wuhu, Anhui, China in 2015.
Participants: Participants were 1075 members of the community from Wuhu city.
Outcome measures: The research team collected self-reported information on sleep quality.
Results: The overall prevalence of self-reported insomnia among older adults were 40.8%. The prevalence of insomnia in females, 259 (59.00%), was significantly higher than in males, 180 (41.00%), with P = .00. For income status, the prevalence of insomnia was significantly higher for participants with less than 10 000 RMB per year income for a family, 191 participants (43.51%), than for participants with higher family incomes, with P = .00. For marital status, the prevalence of insomnia was significantly higher for the widowed participants, 121 participants (24.56%), with P = .01.
Conclusions: Sleep quality for females, low-income families, and widowed people were significantly worse than for people in other categories among older adults in China. Older adults in China need proper interventions for the factors causing poor sleep hygiene.
