Prevalence, awareness, treatment and control of hypertension in Turkey (the PatenT study) in 2003

J Hypertens. 2005 Oct;23(10):1817-23. doi: 10.1097/01.hjh.0000176789.89505.59.


Objective: To determine the distribution of blood pressure (BP) and prevalence, awareness, treatment and control of hypertension in Turkey (PatenT).

Design: A population-based cross-sectional epidemiology survey was carried out in 2003.

Setting: Twenty-six cities from seven geographical provinces of Turkey, with proportional representation of urban and rural populations.

Participants: A two-stage stratified sampling method was used to select a sample of the adult population over 18 years of age. The total number of participants was 4910.

Interventions: Data collection and BP measurements were conducted by specifically trained physicians in the households of the participants.

Main outcome measures: The mean systolic and diastolic BP levels, distribution of blood pressure, prevalence of hypertension (mean systolic BP>or=140 mmHg or mean diastolic BP>or=90 mmHg, or previously diagnosed and/or taking antihypertensive drugs), awareness, treatment and control of hypertension were assessed.

Results: The overall age-adjusted and sex-adjusted prevalence of hypertension in Turkey was 31.8%, and it was higher in women than in men (36.1 versus 27.5%, P<0.001). In the whole group, 32.2% had never had their BP measured. Overall, 40.7% of those with hypertension were aware of their diagnosis, only 31.1% were receiving pharmacologic treatment and only 8.1% had their BP under control. The subjects who were aware and treated had a control ratio of 20.7%.

Conclusions: PatenT data indicate that hypertension is a highly prevalent but inadequately managed health problem in Turkey. There is an urgent need for population-based strategies to improve the prevention, early detection and control of hypertension.
