Characteristics, and disease control and complications of hypertensive patients in primary-care - a community-based study in Singapore.
BACKGROUND
Hypertension is a common chronic condition usually managed by primary-care practitioners in Singapore. This study assessed the characteristics, control and complications of non-diabetic hypertensive patients managed at government primary healthcare clinics.


METHODS
A cross-sectional study involving 9 clinics was conducted over 1-week in 2006. Five hundred and six non-diabetic hypertensive patients were systematically sampled from all clinic attendees. Data relating to socio-demographic, lifestyle factors, treatment and complications were collected by interviewer-administered questionnaires and review of clinic medical records. Blood pressure (BP) measurements were taken with validated automated sets following a standard protocol.


RESULTS
The prevalence of good BP control (<140/90 mmHg) was 37.7% (95% CI: 33.6% to 41.8%). Ninety seven percent were on medication with about half on monotherapy. Seventy percent of patients had a body mass index (BMI) of 23.0 kg/m(2) or higher, 64% did not exercise regularly and 8% were current smokers. After adjusting for age and lifestyle factors, male hypertensive patients had poorer BP control compared to females. Nineteen percent of patients reported at least 1 complication of hypertension, especially cardiac disease. After multivariate analysis and duration of disease, age and the male gender were associated with the presence of hypertensive complications.


CONCLUSIONS
More than half of the patients were not controlled to target levels. Male patients were more likely to have poorer control of hypertension and significantly higher risks of complications. Control of BP could be further improved by lifestyle modifications - weight reduction, promotion of physical activity, healthier eating habits and smoking cessation.
