Background According to the report of World Congress of Cardiology in 2007, 1.5 billion people had hypertension and 45% of hypertensive people were unaware of their condition. In our country, some study had provided estimation of risk factors and prevalence of hypertension, but main characteristics presenting the early detection and control of hypertension have not been studied well and information does not exist.The quality of the control, registration and early detection of hypertension will be improved by studying this topic and complications and mortality due to the hypertension could be decreased.GoalThe aim of our study is to evaluate the current situation of the early detection, registration and control of hypertension, and to describe future strategyObjectives:1. To describe the hypertension awareness and risk factors associated with early detection of hypertension2. To evaluate the current situation of registration system of hypertension and to find out the strategies for renewing registration system3. To investigate the rates of the treatment and control of hypertension, and to survey factors associated with the control of hypertensionMaterials and MethodIt was population based, cross sectional, prospective study. Participants of the study were selected by randomized method.In the study, 1103 individuals, 133 physicians and 2 family hospitals located in Bayanzurkh, Songinokhairkhan districts, were surveyed. The study based on questionnaire and BP measurement which aimed to reveal:• Hypertension awareness (%)• Treatment (%)• Control (%)Software program name: Arterial hypertension registration and control Objectives of the program: to evaluate registration of arterial hypertension, to detect earlier, to determine control level of hypertension Users: family hospitals, family doctorsType of morbidity registration: population basedStatistical analysis was performed with SPSS-17 software program. Single- and multi-factorial analysis was explored by using simple and logistic regression and significance.ResultsIn the study, in total, 1103 people aged of ≥18 years living in Bayanzurkh and Songinokharkhan districts of Ulaanbaatar, have been involved. 37% of all participants were male and 63% were female and mean age of all participants was 40.6±16.1. According to our study, 305 individuals of 431 hypertensive participants (70.8%) were aware of their hypertension. This result was different in gender: 58.0% in male, 79.0% in female. Our research team created software program that can integrate all hypertension data to one database. We are planning to determine unawereness; aware and treated; treated and controlled; and uncontrolled levels by using this software and to introduce the program created by us to all primary level physicians in order to use routinely.Conclusions:1. Among hypertensive individuals, awareness of hypertension was 70.8%. Factors such as young age (<35), single people and not measuring BP for the last one year influence negatively on early detection of hypertension (p<0.05).2. Current method of hypertension registration is not proper at the time. Therefore, we concluded that renewing of the arterial hypertension registration database and conversion it into electronic type is convenient to control arterial hypertension and to provide integration.3. Treatment level of arterial hypertension was 39.9%, controlled arterial hypertension among all hypertensive population - 10.2% and among treated population – 25.2%.
