To investigate sleep problems among middle-aged and elderly individuals from ethnic regions in Yunnan Province, China, to identifiy associated factors, and to inform targeted interventions that improve their sleep quality.
Sleep problems were defined as the occurrence of any of the following: (1) rhythm disorders (e.g., late bedtime, early or late waking); (2) insomnia (e.g., difficulty falling asleep, frequent awakenings, nocturia, or <7 hours’ sleep); or (3) hypersomnia (≥9 hours’ sleep). We conducted a stratified random cluster survey among adults aged≥45 years in 9 prefectures/cities in Yunnan Province. Data on sleep, demographics, physical/mental health, behaviors, and social relationships were collected via a self-developed questionnaire. Logistic regression identified associated factors.
Among 5 180 middle-aged and elderly adults, 76.5% reported sleep problems: insomnia (63.8%), rhythm disorders (36.4%), and hypersomnia (21.3%). The Yao group had the highest rates of insomnia and rhythm disorders; the Lisu group had the highest hypersomnia rate. Logistic regression revealed that women from the Jinuo, Lisu, Wa, Nu, and Bulang groups were significantly more likely to report sleep problems (all P<0.05). Chronic conditions increased likelihood of sleep problems in the Han, Jinuo, Yi, and Lisu groups; frequent pain increased likelihood in the Han, Hani, Zhuang, Yao, Jinuo, Yi, and Bulang groups; depressive symptoms increased likelihood in the Han, Yao, Jinuo, Lisu, Lahu, Wa, Nu, and Bulang groups; lack of social activity in the past 30 days increased likelihood in the Han, Hani, Dai, and Yao groups; and daily smoking was associated with lower likelihood in the Han, Yi, Lisu, and Bulang groups (all P<0.05).
Sleep problems are highly prevalent among the middle-aged and elderly individuals in ethnic regions of Yunnan Province. A multitude of factors, including chronic diseases, pain, depression, and health behaviors, are interrelated. It is imperative to develop precise and differentiated sleep intervention strategies in conjunction with the demographic characteristics and health indicators of ethnic groups.
