A7116 Preventing excessive alcohol intake, smoking and obesity may reduce blood pressure results from the screening of 47000 adults in Emin, China

Abstract

Objectives: Prehypertenion (PHT) has a higher risk of developing hypertension (37.3–49.5% over 4 years) the leading preventable cause of cardiovascular disease (CVD).Therefore, to coordinate more efforts to control hypertension and CVD, we estimated PHT prevalence, related factors and clustered CVD risk factors in Emin Xinjiang, where control of hypertension is lower than national average (10% vs 15.9%) in China. Methods: From 2014 to 2016, we surveyed1/3 of adult residents of Emin (population 160000) for hypertension screening. PHT was defined as not on anti-hypertensive medications and SBP of 120–139mmHg and /or DBP of 80–89mmHg. We compared the PHT prevalence with different gender, age groups, and area (urban, agricultural, stock-raising), and related factors and clustered CVD risk factors in PTH. Modifiable clustered risk factors included overall and abdominal obesity, smoking and drinking. Results: 47040 adult residents were screened; 48.5% were women. The overall prevalence of PHT and hypertension was 31.2%and 26.6%, respectively. The age-adjusted PHT prevalence was higher in men (37.4%) than in women (24.4%). PHT prevalence is the highest (37.9%) in 30–39 age groups and highest in urban area (31.6%). Overweight (OR = 1.85), overall and abdominal obesity (OR = 2.45 and 1.45), smoking (OR = 1.12), and alcohol intake (OR = 1.16) were associated with higher PHT prevalence. Compared to normotensive subjects, the prevalence of clustering 1 (23.0% vs 22.2%), 2 (32.4% vs 24.8%), 3 (8.3% vs 6.1%) and 4 (5.2% vs 3.8%) CVD risk factors were significantly higher in PHT. Conclusion: PHT is highly prevalent in Xinjiang, particularly in men, younger population and in those from urban area. Control of alcohol drinking, smoking and body weight may be at high priority of health promotion.
