ObjectivesTo examine the relationship between sleep duration and hypertension of migrant workers aged 18–59 years in China.DesignPopulation-based cross-sectional study using a complex survey sampling design.ParticipantsThere were 43 655 subjects in our analysis, after excluding people with missing information for key exposure and outcome variables and abnormal values for sleep duration (≤2 or ≥17 hours).Primary outcome measureHypertension was defined as systolic blood pressure (BP) ≥140 mm Hg and/or diastolic BP ≥90 mm Hg, or self-reported history of hypertension diagnosis in hospitals at the township (community) level or above and use of hypertensive medicine in the last 2 weeks.ResultsOf 43 655 subjects, 15.6% (95% CI 15.1% to 16.1%) of migrant workers had hypertension. The prevalence of hypertension decreased with the increased sleep duration, both in males and females. Logistic regression models, using 7–8 hours sleep/day as the reference, showed a greater odds for hypertension among men and women who reported <6 hours of sleep after adjusting for sociodemographic characteristics, behavioural risk factors, body mass index, diabetes, stroke and myocardial infarction (men: OR 1.26; 95% CI 1.03 to 1.54, women: OR 1.55; 95% CI 1.13 to 2.06, pinteraction =0.096). Further stratified by age and migration time, it revealed that among adults less than 45 years old, those sleeping 9 or more hours had adjusted odds for hypertension of 0.82 (95% CI 0.72 to 0.93, pinteraction=0.020),while there was no evidence of an association between sleep duration and hypertension among adults aged 45–59 years. Among adults whose migration time was less than 4.5 years, those sleeping 9 or more hours had adjusted odds for hypertension of 0.80 (95% CI 0.68 to 0.94, pinteraction=0.097).ConclusionThe association between sleep duration and hypertension varies by age. Short sleep duration (<6 hours) is associated with an increased prevalence of hypertension in both genders.

ObjectiveTo investigate the proportion of willingness for community-based and institutional care and their correlating factors among older adults in Zhejiang Province, China.DesignCross-sectional study.SettingThe Sixth National Health Service Survey, carried out in Zhejiang, China.Participants7300 eligible older adults aged 60 years or older.Main outcomes measuresWillingness for community-based and institutional eldercare.ResultsThe average age of the participants was 69.0±7.3 years. 50.9% of the participants were males, and 49.1% were females. 19.2% came from urban areas and 80.8% were from rural areas. The percentage of willingness for community-based and institutional eldercare was 2.7% and 3.8%, respectively. The corresponding figures for females were 2.9% and 3.5%, respectively, and for males were 2.5% and 4.1%, respectively. Factors positively associated with willingness for community-based eldercare included living in urban areas, high educational attainment, more frequent active exercise and living alone. Factors positively associated with willingness for institutional eldercare included age, living at urban areas, high education attainment, more frequent active exercise and receiving assistance with daily living.ConclusionsFamily eldercare was the priority for older adults compared with community-based and institutional eldercare in Zhejiang. The willingness for community-based and institutional eldercare among older adults was affected not only by the older adults themselves, but also by community and family members.

BackgroundThe China Mental Health Survey was carried out using the same sampling frame with the China Chronic Diseases and Risk Factors Surveillance. This paper explores the relationship between the disability and the comorbidity of mood disorders and anxiety disorders with diabetes and hypertension.MethodsA large-scale nationally representative sample with both mental disorders and chronic diseases was collected from 157 Disease Surveillance Points in 31 provinces across China. Face-to-face interviews were conducted by trained lay interviewers to make diagnoses of mood disorders and anxiety disorders using the Composite International Diagnostic Interview. Diabetes and hypertension were diagnosed from self-report and blood examination or body measurement. Sampling design weights, non-response adjustment weights, and post-stratification adjustment weights were applied during the analyses of comorbidity and disability.ResultsTotally 15,000 respondents had information of mental disorders and physical diseases. In the patients with mood disorders or anxiety disorders, the weighted prevalence rates of diabetes or hypertension were not higher than those in persons without the above mental disorders, but the weighed disability rates increased when having the comorbidity of hypertension (P &lt; 0.05). The severity of disability was higher among patients with comorbidity of diabetes and anxiety disorders, or hypertension and mood disorders, compared with that among patients without the physical comorbidity (P &lt; 0.05). After adjusted by age, gender and education, patients with comorbidity of mental disorders and physical disorders had the highest disability, followed by the patients with mental disorders only, and physical diseases only.ConclusionsThe disability of mood disorders and anxiety disorders comorbid with diabetes and hypertension are more serious than that of any single disease. The relationship of mental and physical diseases is worth exploring in depth for comprehensive and integrated intervention to decrease the disability.
