Major inducing factors of hypertensive complications and the interventions required to reduce their prevalence: an epidemiological study of hypertension in a rural population in China

Abstract

BackgroundThe complications of hypertension cause severe health problems in rural areas in China. We (i) screened the major factors inducing hypertensive complications and provided intervention measures; and (ii) verified the efficacy of the New Rural Cooperative Medical Scheme (NRCMS; a medical insurance scheme for rural residents) for hypertension management.MethodsA survey was conducted in the villages of Yunnan (an underdeveloped province in southwest China). The NRCMS was initiated there in 2005. Data were collected through questionnaires, physical examination, electrocardiography, as well as blood and urine tests. To detect factors inducing hypertension complications, a generalized estimating equations model was developed. Multivariable logistic regression was used to analyze influencing factors for hypertension control.ResultsPoor management of hypertension was observed in women. Being female, old, poorly educated, a smoker, ignorant of the dangerousness of hypertension, and having uncontrolled hypertension made patients more prone to hypertension complications. Combination therapy with ≥2 drugs helped control hypertension, but most rural patients disliked multidrug therapy because they considered it to be expensive and inconvenient. The NRCMS contributed little to reduce the prevalence of complications and improve control of hypertension.ConclusionsThe present study suggested that the NRCMS needs to be reformed to concentrate on early intervention in hypertension and to concentrate on women. To increase hypertension control in rural areas in China, compound products containing effective and inexpensive drugs (and not multidrug therapy) are needed.

Assessment of Blood Pressure Control among Hypertensive Patients in Southwest Ethiopia

“…For many hypertensive patients, combination therapy is believed to achieve better BP control than monotherapy [43]. In our study, 12.6% of the participants were on monotherapy despite uncontrolled blood pressure.…”

Hypertension prevalence, awareness, treatment, and control in 115 rural and urban communities involving 47 000 people from China

“…Although there is no information on the actual doses of drugs received, less than 20% received a combination of two or more drugs and less than 10% received a western drug plus a TCD. TCDs, which are combinations of two or more older western drugs such as diuretics, hydralazine and central acting vasoactive drugs such as reserpine or clonidine in lower doses, plus traditional Chinese medications, have been used in China since the 1960s [17,18]. They have been recognized by the health authorities as equivalent treatment and have proven to be popular among the participants.…”

“…TCDs consisted of combinations of traditional Chinese medications, with or without low doses of older Western drugs such as thiazide diuretics, hydralazine, or reserpine. They are more widely accepted by Chinese people because of low cost and widespread availability [17].…”

How hypertensive patients in the rural areas use home blood pressure monitoring and its relationship with medication adherence: A primary care survey in China

“…A survey conducted in southern China showed that 13.5% of hypertensive patients living in urban regions controlled their hypertension; this proportion was higher than that in rural regions (3.4%) [4]. Considering that approximately 57% of the total population in China resides in the rural areas, the largest number of hypertensive patients reside in rural areas as well [5]. Poor management of hypertension in rural areas has led to a heavy burden on public health in China.…”
