[Characteristics of hypertension prevalence and related factors in rural area in Sichuan].

OBJECTIVE: To understand the prevalence, awareness, treatment and control of hypertension in rural area in Sichuan province. METHODS: The cross-sectional data of 55 687 subjects who were enrolled into the China Kadoorie Biobank study from Pengzhou in southwestern China were used to analyze the prevalence, awareness, treatment and control of hypertension among local residents. RESULTS: The prevalence of hypertension among population aged 30-79 years old was 25.2%. The awareness rate of self hypertension status, the treatment rate and the control rate of hypertension were 24.7%, 14.7% and 3.7%, respectively. The prevalence of hypertension, the awareness rate of self hypertension status, the treatment rate and the control rate of hypertension were associated with the socio-demographic characteristics of the subjects. The prevalence of hypertension in winter (70%-80%) was higher than that in summer, while the awareness rate, the treatment rate and the control rate of hypertension in winter were much lower than those in summer. Among the hypertension patients, the rates of smoking and alcohol use were high, the dietary habit was bad, physical activities were less and the prevalence of obesity was higher. The lifestyles of the hypertension patients were improved in those who know about their disease status. CONCLUSION: The prevalence of hypertension was high, but the awareness rate of self hypertension status, the treatment rate and the control rate of hypertension were low in rural area in Sichuan. It is necessary to strengthen the health education in young population and the treatment and control of hypertension in old population. Meanwhile, the management of hypertension patients should be standardized.

Depression, anxiety, and prevalent diabetes in the Chinese population: findings from the China Kadoorie Biobank of 0.5 million people.

OBJECTIVE: Despite previous investigation, uncertainty remains about the nature of the associations of major depression (MD) with type 2 diabetes mellitus (T2DM), particularly in adult Chinese, and the relevance of generalized anxiety disorder (GAD) for T2DM. METHODS: Cross-sectional data from the China Kadoorie Biobank Study, a sample of approximately 500,000 adults from 10 geographically defined regions of China, were analyzed. Past year MD and GAD were assessed using the Composite International Diagnostic Inventory. T2DM was defined as either having self-reported physician diagnosis of diabetes at age 30 or later ("clinically-identified" cases) or having a non-fasting blood glucose≥11.1mmol/L or fasting blood glucose≥7.0mmol/L but no prior diagnosis of diabetes ("screen-detected" cases). Logistic regression was used to assess the relationship between MD and GAD with clinically-identified and screen-detected T2DM, adjusting for demographic characteristics and health behaviors. RESULTS: The prevalence of T2DM was 5.3% (3.2% clinically-identified and 2.1% screen-detected). MD was significantly associated with clinically-identified T2DM (odds ratio [OR]: 1.75, 95% confidence interval (CI): 1.47-2.08), but not with screen-detected T2DM (OR: 1.18, 95% CI: 0.92-1.51). GAD was associated with clinically-identified (OR: 2.14, 95% CI: 1.60-2.88) and modestly associated with screen-detected (OR: 1.44, 95% CI: 0.99-2.08) T2DM. The relationship between MD and GAD with T2DM was moderated by obesity. CONCLUSION: MD is associated with clinically-identified, but not screen-detected T2DM. GAD is associated with both clinically-identified and screen-detected T2DM. The relationship between MD and T2DM is strongest among those who are not obese.
