Temporal trends in Prevalence, Awareness, Treatment, and Control of Hypertension from 2000 to 2010 in Chengdu, China.

This study aimed to describe trends in prevalence, awareness, treatment, and control in hypertension in Chengdu from 2000 to 2010. Two community-based cross sectional surveys were conducted among those aged 40-79 years in 2000 (n = 4850) and 2010 (n = 5456). Demographic characteristics, blood pressure (BP) and associated risk factors were examined. Mean systolic and diastolic BP increased from 117.8 ± 33.9 to 132.1 ± 21.2 mmHg (P < 0.001), and 75.3 ± 19.1 to 79.3 ± 11.2 mmHg (P < 0.001) over past decade, respectively. The prevalence of hypertension increased from 27.7 to 29.4% (P < 0.001). Awareness increased from 37.7 to 42.5% (P < 0.001). The overall treatment rate increased from 20.9 to 28.0% (P < 0.0001), while among subjects aware of hypertension, treatment increased from 46.9 to 65.8% (P < 0.001). In hypertensives, control increased from 6.8 to 6.9% (P = 0.6684). Nevertheless, in hypertensives aware and treated, control decreased from 32.5 to 24.3% (P = 0.020). Hypertension prevalence increased in the last decade, while awareness, treatment and control remained considerably low in Chengdu.

Hyperuricemia is associated with cardiovascular diseases clustering among very elderly women - a community based study in Chengdu, China.

Cardiovascular epidemiological features among very elderly Chinese are still uncertain. This study aimed to describe the distribution of cardiovascular diseases and sex difference, and investigate potential risk factors for diseases clustering among very elderly Chinese. From May 2013 to May 2015, a total of 1056 very elderly were sampled in this cross-sectional study. Demographic characteristics collection, physical examination and biochemical analysis were performed. Totally, 1038 participants (men: 49.8%) with a median age of 83.0 years (age range: 80.0-100.0 years) were included. In this very elderly group, the prevalences of hypertension, diabetes mellitus, renal dysfunction, hyperuricemia, obesity, visceral obesity, and hypercholesterolaemia were 76.9%, 20.0%, 23.3%, 33.0%, 9.4%, 54.5% and 35.8%, respectively. About 17.5% of very elderly (men vs. women: 15.1% vs 19.8%, p = 0.007) have ≥3 cardiovascular diseases clustering. Logistic analysis found that hyperuricemia (odds ratio 3.850, 95%CI 2.189-6.770) was associated with of cardiovascular diseases clustering among very elderly women. Prevalences of prehypertension, hyperuricemia, visceral obesity and dyslipidaemia are apparent in very elderly women, while diabetes mellitus, renal dysfunction are common in very elderly men. Women are more likely to have ≥3 cardiovascular diseases. Hyperuricemia is associated with cardiovascular diseases clustering among very elderly women.
