PP.16.22] HOME BLOOD PRESSURE MONITORING SURVEY OF CHINA (HBPM-C)

Abstract

Objective: To investigate the use of home blood pressure monitoring(HBPM) in Chinese hypertensives in cities. Design and method: We designed and delivered 2040 questionnaires in 23 outpatients of hospitals or community-based clinics in Beijing and other cities from 5/2013∼8/2013 for the survey. The questionnaires included basic demographic information, history of hypertension and complications, owning rate and kinds of HBPM devices and questions on awareness and behavior model on HBPM, involving the upper limit value of systolic and diastolic pressure, time, frequency and methods of measuring. Results: 1992 hypertensive subjects complete questionnaires (response rate is 1992/2040). 50.3% were from central hospital, 41.2% were from community-based hospitalt, 48.6% were male. Nearly one third subjects accompanied with other cardiovascular risk factors, including smoking, alcohol use, higher salt intake, irregular exercise, cardiovascular disease (CVD) family history, indicating the urgent need of life style changes in China. More than 20% subjects complicated with CVD or diabetes. About 85% subjects have HBPM device and received the advice for HBPM as referring to a doctor, respectively. 10% subjects gave an accurate answer on the cut point of SBP (<135 mmHg) or DBP (<85 mmHg) of HBPM. Nearly 50% consider <140/90 mmHg as the normal value for HBPM. As for the frequency of HBPM, 30% measure everyday and about 7% subjects never used HBPM despite the device was available. One third subjects used arm HBPM device and less than 18% were wrist style. More than one fourth subjects use HBPM only as having a symptom or uncomfortable. The others varied from raise up, on bed or morning. One third measured only once each time, more than one half subjects never record the readings of HBPM, and about 40% subjects never showed the readings of HBPM to the referral doctors. Conclusions: Despite the high availability of HBPM devices in Chinese family in cities, the awareness and utilizing rate of HBPM are still low in China, indicating a compelling need for education and training on BP measurement and monitoring in Chinese subjects with hypertension.
