Objective: Hypertension incidence is an important determinant of hypertension prevalence and progression. Few studies have been published on hypertension incidence in developing countries despite the high prevalence observed. The aim of this study was to investigate the incidence of hypertension in Turkey. Methods: The study was designed as an epidemiological cohort study which included the population of the Prevalence, awareness, treatment and control of hypertension in Turkey (PatenT) Study which had 4910 volunteers. Blood pressure measurements were performed three times and a questionnaire was used to obtain data on the present status of hypertension with regards to distributions and alterations of risk factors. Results: In the present study, 4008 (81.6%) participants of the PatenT Study population were contacted after 4 years. After excluding 173 dead and 67 pregnant individuals, the study cohort comprised of 3768 individuals. The overall 4-year incidence rate of hypertension was 21.4%; it reached a maximum of 43.3% in individuals over 65 years of age. Age, initial blood pressure category, and body mass index were the best predictors of the hypertension incidence rate. Multivariate logistic regression analysis revealed that age, obesity, alcohol consumption, and living in rural areas were significant predictors of hypertension. Conclusion: Follow-up periods scheduled considering age, initial blood pressure category, and body mass index are important for the early determination of hypertension. As there are limited data regarding hypertension incidence in developing countries, the results of data collected in this study might serve as a model. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Blood Pressure | Year: 2010

This population-based epidemiological study was aimed to evaluate the daily salt intake and its relation to blood pressure in a representative group of Turkish population. The enrolled normotensive and hypertensive individuals (n = 1970) completed a questionnaire including demographics, dietary habits, hypertension awareness and drug usage. Blood pressure was measured and to estimate salt consumption, 24-h urine samples were collected. The daily urinary sodium excretion was 308.3 ± 143.1 mmol/day, equal to a salt intake of 18.01 g/day. Salt intake was higher in obese participants, rural residents, participants with lower education levels and elderly. A positive linear correlation between salt intake and systolic and diastolic blood pressures was demonÖstrated (r = 0.450, p = 0.020; r = 0.406, p = 0.041; respectively), and each 100 mmol/day of salt intake resulted in 5.8 and 3.8 mmHg increase in systolic and diastolic blood pressures, respectively. Salt intake and systolic blood pressure was significantly correlated in normal weight individuals (r = 0.257, p < 0.01). The Turkish population consumes a great amount of salt; salt intake and blood pressure was positively correlated. Efforts in sodium restriction are therefore crucial in the management of hypertension as part of national and global health policies. © 2010 Scandinavian Foundation for Cardiovascular Research.

The purposes of this study were to detect the prevalence of ownership of a home sphygmomanometer among hypertensive subjects through a nation-wide survey, to investigate parameters affecting ownership of a sphygmomanometer, to compare how home blood pressure monitoring (HBPM) was actually used in daily practice with some aspects of the current guidelines, and to discuss what we implemented to increase the reliability of HBPM in a developing country. A total of 2747 hypertensive patients from 34 cities, representative of the Turkish population, were enrolled in the study. A multiple-choice questionnaire was administered to each participant using the computer-assisted telephone interviewing method. Among 2747 hypertensive patients, 1281 of them (46.6%) had a home sphygmomanometer. Most of the patients were using wrist devices. The factors associated with ownership of a sphygmomanometer were female gender, older age, obesity, higher educational status, higher income level, living in urban areas, awareness of hypertension and anti-hypertensive drug usage. Only 16% of the devices were used on the advice of a physician. The patients learned usage of their device mainly from the sellers and their relatives. The ownership of a home sphygmomanometer is common among hypertensive patients in Turkey, but regular monitoring of blood pressure before physician visits is rare despite common ownership of these devices. Daily practice of HBPM in Turkey was far from the recommendations of the current guidelines. More effort is needed to improve the reliability of HBPM. © 2012 The Japanese Society of Hypertension All rights reserved. Source
