目的了解中国北方农村社区老年人睡眠质量差的患病率及相关因素。方法于2014年8 - 12月采用横断面调查方法，在山东省西部阳谷县盐楼镇招募年龄在65岁及以上的2195名参与者。通过结构化访谈收集人口统计、健康相关行为和临床状况的数据。匹兹堡睡眠质量指数（PSQI）用于评估睡眠质量和模式。睡眠质量差被定义为PSQI得分为bb70。我们采用多重逻辑模型将睡眠质量差与各种因素联系起来。结果总睡眠质量差患病率为33.8%，女性为39.2%，男性为26.3% （P < 0.01）。最常见的异常睡眠域是睡眠潜伏期延长（39.7%）、睡眠持续时间缩短（31.0%）和习惯性睡眠效率降低（28.8%）。多元logistic回归分析显示，睡眠质量差与女性性别（OR = 1.76, 95% CI 1.46-2.12）以及高血压（OR = 1.28, 95% CI 1.06-1.54）、冠心病（OR = 1.60, 95% CI 1.27-2.00）和慢性阻塞性肺疾病（OR = 1.82, 95% CI 1.34-2.49）等临床合并症显著相关。结论中国农村老年人睡眠障碍发生率较高。可改变的危险因素，如心脏代谢危险因素和疾病与睡眠质量差有关，这可能是改善老年人睡眠质量干预的潜在目标。
Objective To investigate the prevalence and associated factors of poor sleep quality among community-dwelling elderly population in a rural area of Northern China. Methods We conducted a cross-sectional survey in August-December 2014 and recruited 2195 participants who were aged 65 years or older and living in Yanlou Town of Yanggu County in western Shandong Province, China. Data on demographics, health-related behaviors, and clinical conditions were collected through structured interviews. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality and patterns. Poor sleep quality was defined as a PSQI score > 7. We employed multiple logistic models to relate poor sleep quality to various factors. Results The overall prevalence rates of poor sleep quality were 33.8% in the total sample, 39.2% in women and 26.3% in men (P < 0.01). The most common abnormal sleep domains were prolonged sleep latency (39.7%), decreased sleep duration (31.0%), and reduced habitual sleep efficiency (28.8%). Multiple logistic regression analyses revealed that poor sleep quality was significantly associated with female sex (OR = 1.76, 95% CI 1.46-2.12) and clinical comorbidities such as hypertension (OR = 1.28, 95% CI 1.06-1.54), coronary heart disease (OR = 1.60, 95% CI 1.27-2.00), and chronic obstructive pulmonary disease (OR = 1.82, 95% CI 1.34-2.49). Conclusions The sleep disorders were highly prevalent among the elderly in rural China. Modifiable risk factors such as cardiometabolic risk factors and disorders were associated with poor sleep quality, which might be potential targets for interventions to improve sleep quality in elderly population.
