| Objective: To descriptive subjective sleep disorders and sleep habits to detective related factors of subjective sleep quality in the elderly in community.Methods: Using multi-stage stratified cluster sampling method, 100 survey spot was selected in Tianjin community total of 3272 elderly people aged 60 and above came from the Tianjin Mental Health Survey conducted during July to December in 2011. They were interviewed with questionnaire including general demographic data of elderly people(include urban and rural, age, gender, marriage, educational level, etc.), General Healthy Questionnaire-12, the Pittsburgh Sleep Quality Index(PSQI) and sleep habits questionnaire. The PSQI total score >7 was defined as poor subjective sleep quality. Chi-square test and Kruskal-Wallis rank sum test was used to conduct univariable analysis, and logistic regression was used to analyze the related factors to subjective sleep quality.Results: 1. Among 15538 questionnaires returned, 11618 questionnaires were validfor analysis, which conferred a rate of 74.7%. Total of 3272 elderly people aged 60 and above were selected out to study. 2. The highest incidence of sleep complaint was “difficult to fall asleep at night(24.1%) ”, then were “wake up in the middle of the night or early morning(21.8%)”,, “get up to use the bathroom(15.0%)”, “have pain(8.3%)”, “feel too hot(5.2%)”, “had bad dreams(4.8%)”, “cannot breathe comfortably(4.7%)”, “cough or snore loudly(4.4%)”, “feel too cold(1.6%)”. The prevalence of older women's subjective sleep disorder was generally higher than men. 3. Average bedtime was 21:55; 59.4% of individuals go to bed between 22:00 and 23:59; 80.2% of the sample reported they could fall asleep in 30min; Average morning rise time was 05:53; 95.1% individuals got up before 08:00. The average sleep latency was 28 min. Average sleep duration of the sample was 7.2 hours; the older elderly were likely to go to bed earlier than younger elderly. Men has statistic significant shorter sleep latency(15min) than women(52.2%VS.42.8%). The percentage of people who slept more 7 hours in 80 aged and above was higher than that in 60-69 and 70-79.4. Logistic regression analysis showed that male sex(OR=0.60, 95%CI :0.44~0.82)was protective factor for subjective sleep quality. GHQ score?4(OR=2.96,95%CI : 2.11~4.16), morning rising time(reference group:get up before 06:00) [06:00~07:59(OR=1.46, 95%CI=1.03~2.07); 08:00~09:59(OR=2.58, 95%CI: 1.27~5.28); get up after 10:00(OR=12.84, 95%CI: 2.17~75.84)],long sleep latency(reference0group:0-15min)[16-30min:0(OR=6.06,095%CI:3.54~10.37);31-60min:(OR=52.21, 95%CI: 30.1~90.54); 60 min above(OR=138.14, 95%CI: 73.96~258.04)], shorter sleep duration(reference group:7h~)[6-7h(OR=3.32,95%CI:2.26~4.88);5-6h(OR=10.72,95%CI:6.83~16.83);0-5h:(OR=43.9, 95%CI=23.7~81.39)] and irregular sleep in last month(OR=1.29,95%CI:1.07~1.57)were associated with elevated risks for good subjective sleep quality.Conclusions: 1. The incidence of sleep disorders in the elderly community was high. 2. Community elderly women were high-risk groups of subjective sleep disorders, this group of people should be concerned. 3. Sleep habits in elderly vary with different sex and age. 4. The sleep quality is related to sleep habits. It indicates that sleep quality might be improved by changing sleep habits. |
