Insomnia and the inability to sleep affect people's health and well-being. However, its systematic estimates of prevalence and distribution in the general population in China are still lacking. A population-based cluster sampling survey was conducted in the rural and urban areas of Hunan, China. Subjects (n = 26,851) were sampled from the general population, with a follow-up using the Pittsburgh Sleep Quality Index (PSQI) for interview to assess quality of sleep and Insomnia (PSQI score >5). While the overall prevalence of insomnia was 26.6%, and little difference was found between males (26.3%) and females (27.0%); the mean PSQI score was 4.26 (±2.67), and significant higher in females (4.32 ± 2.70) than males (4.21 ± 2.64, p = 0.003). Individuals in the rural areas tended to report a higher PSQI score (4.45 ± 2.81) than urban residents did (4.18 ± 2.60) (p < 0.001) and the estimates of prevalence of insomnia was 29.4% in the rural areas, significant higher than 25.5% in the urban areas (p < 0.001). Multiple logistic regression analysis showed that female gender, older age, higher level of education, being unmarried, living in the rural area, cigarette smoking and alcohol drinking were associated with insomnia. Our study may provide important information for general and mental health research.
失眠和睡眠不足会影响人们的健康和福祉。然而，中国一般人群中失眠的系统估计患病率和分布情况仍缺乏。我们在中国湖南的城乡地区进行了一项基于人群的聚类抽样调查。采用匹兹堡睡眠质量指数（PSQI）对受访者进行访谈，以评估睡眠质量和失眠（PSQI 得分>5），对从一般人群中抽取的样本（n=26851）进行随访。总的失眠患病率为 26.6%，男性（26.3%）和女性（27.0%）之间差异无统计学意义；PSQI 平均得分为 4.26（±2.67），女性（4.32±2.70）显著高于男性（4.21±2.64，p=0.003）。农村地区的个体报告 PSQI 评分较高（4.45±2.81），显著高于城市居民（4.18±2.60）（p<0.001），农村地区失眠的患病率估计值为 29.4%，显著高于城市地区的 25.5%（p<0.001）。多因素 logistic 回归分析显示，女性、年龄较大、文化程度较高、未婚、居住在农村、吸烟和饮酒与失眠有关。我们的研究结果可能为一般人群和精神健康研究提供重要信息。
