ABSTRACT

<p><b>OBJECTIVE</b>To investigate the current status and association between movement disorders, constipation and sleep disturbances in the elderly population of China.</p><p><b>METHODS</b>A total of 42 353 subjects aged over 60 years old from Chinese Chronic Non-communicable Disease & Risk Factor Surveillance (2010) was selected in our study. The information on movement disorders, constipation and sleep disturbances was collected by standardized questionnaire interview. The prevalence and association of self-reported movement disorders, constipation and sleep disturbances was measured according to different gender, age groups and regions.</p><p><b>RESULTS</b>The study was conducted among 42 353 old adults, including 21 893 males (51.7%) and 20 460 females (48.3%); 17 917 from urban areas (42.3%) and 24 436 from rural areas (57.7%); and the proportion of elderly from eastern, central and western regions were 37.9% (16 031 subjects), 29.1% (12 345 subjects) and 33.0% (13 977 subjects) respectively. After weighted complex analysis, the data showed that among the elderly population over 60 years old in China, the self-reported rates of movement disorders, constipation and sleep disturbances were all age-related, rising up with the age increasing. The rates of 60-64 age group were 2.8% (95%CI1.9%-3.7%), 3.6% (95%CI3.1%-4.1%) and 12.4% (95%CI11.0%-13.8%);and in ≥ 80 age group, the rates were 13.2% (95%CI10.2%-16.1%), 8.8% (95%CI7.1%-10.6%) and 19.1% (95%CI16.3%-21.9%). The self-reported rate of movement disorders was 5.7% (95%CI 4.5%-7.0%); the prevalence of constipation was 5.1% (95%CI 4.4%-5.7%), which was higher among women (5.8%, 95%CI 5.0%-6.6%) than it among men (4.3%, 95%CI 3.7%-4.8%) (χ(2) = 23.40, P < 0.05), and higher among subjects from urban areas (6.0%, 95%CI 5.1%-7.0%) than from rural areas (4.6%, 95%CI 3.8%-5.4%) (χ(2) = 5.62, P < 0.05); the prevalence of self-reported sleep disturbances was 14.2% (95%CI 12.7%-15.8%), higher in women (17.4%, 95%CI 15.4%-19.3%) than in men (11.0%, 95%CI 9.7%-12.2%) (χ(2) = 172.05, P < 0.05); the prevalence of movement disorders in people with constipation (16.3%, 95%CI 12.7%-19.9%) was much higher than it in people without constipation (5.2%, 95%CI 4.0%-6.3%) (χ(2) = 242.73, P < 0.05); and the prevalence of movement disorders in people with sleep disturbances (13.0%, 95%CI 10.6%-15.4%) was much higher than it in people without sleep disturbances (4.5%, 95%CI 3.5%-5.5%) (χ(2) = 688.80, P < 0.05).Logistic regression analysis showed that constipation and sleep disturbances would increase the risk of movement disorders, with the OR (95%CI) at 2.93 (2.57-3.33) and 2.73 (2.48-3.02), respectively.</p><p><b>CONCLUSION</b>The present study showed that self-reported rates of movement disorders, constipation and sleep disturbances all rose up with age increasing in the elderly. The movement disorders was associated with constipation and sleep disturbances.</p>
