Prevalence and risk factors of ischemic stroke in rural areas of Liaoning province / 中华心血管病杂志

Objective: To explore the prevalence and risk factors of ischemic stroke in rural areas of Liaoning province. Methods: The study was a cross-sectional survey. From September 2017 to May 2018, a total of 10 926 rural residents aged ≥40 years were investigated in Chaoyang county, Lingyuan, Liaoyang county and Donggang city of Liaoning province. The investigation included questionnaire survey, physical examination and laboratory examination.Univariate and multivariate logistic regression models were used to analyze the risk factors of ischemic stroke. Results: The prevalence of ischemic stroke in the rural areas of Liaoning province was 5.51% (602/10 926), and the standardized prevalence rate was 4.04%. The standardized prevalence rate of male (5.05%) is higher than that of female (3.44%). The prevalence of ischemic stroke increased with age in both males (P<0.01) and females (P<0.01). Multivariate logistic regression analysis showed that age increase(compared with 40-49 years old group, 50-59 years old, OR=2.08, 95%CI 1.31-3.30, P=0.02; 60-69 years old, OR=3.90, 95%CI 2.51-6.05, P<0.01; 70-79 years old, OR=5.32, 95%CI 3.37-8.34, P<0.01; ≥80 years old, OR=3.64, 95%CI 2.00-6.62, P<0.01), male(OR=2.35, 95%CI 1.95-2.84, P<0.01),family history of stroke(OR=2.18, 95%CI 1.83-2.60, P<0.01),coronary heart disease (OR=2.01, 95%CI 1.52-2.66, P<0.01), hypertension (OR=2.82, 95%CI 2.21-3.60, P<0.01), diabetes mellitus (OR=1.36, 95%CI 1.11-1.67, P=0.03) and overweight/obese (OR=1.22, 95%CI 1.02-1.47, P=0.03) were the major risk factors of ischemic stroke. Conclusions: The prevalence of ischemic stroke in rural areas of Liaoning province is high. Age, male, family history of stroke, coronary heart disease, hypertension, diabetes mellitus, overweight/obesity are the risk factors of ischemic stroke in rural areas of Liaoning province.

Prevalence, awareness, treatment and control of hypertension in rural adult residents of Liaoning Province / 中华心血管病杂志

<p><b>OBJECTIVE</b>The objective of this study was to estimate the current status of prevalence, awareness, treatment and control rate of hypertension in adult residents living in rural area of Liaoning Province, North China.</p><p><b>METHODS</b>The screening was finished in 2008, probability proportional to size sampling method was used to select the representative sample. Blood pressure was measured in 153481 adults (aged > 35 yr), information on history of hypertension and use of antihypertensive medications was obtained by use of a standard questionnaire.</p><p><b>RESULTS</b>Overall, hypertension prevalence rate was 41.9%, the age-specific hypertension prevalence rate was 25.0%, 37.7%, 50.2%, and 64.9% in men and 22.1%, 41.1%, 56.6% and 70.2% in women age 35 to 44 years, 45 to 54 years, 55 to 64 years, and above 65 years, respectively. Among hypertensive patients, awareness rate was only 54.1%, 39.7% patients received antihypertensive medication and blood pressure control rate (< 140/90 mm Hg) was 6.9% in all participants and was 9.3% in treated hypertensive patients.</p><p><b>CONCLUSION</b>Our results indicates that hypertension prevalence is highly while awareness, treatment and control rate of hypertension was low in rural areas of northeast China. These results underscore the urgent need to develop comprehensive strategies to improve prevention, detection, and treatment of hypertension in rural population of Liaoning province.</p>
