title: The prevalence of pre-hypertension and hypertension in an Iranian urban population.
abstract: OBJECTIVE
  To determine the prevalence of hypertension and pre-hypertension and its determinants in the 40-64 year old population of Shahroud in the north of Iran.
  
  
  METHODS
  The blood pressure of 5,190 of the 40-64 year old people participating in the first phase of Shahroud Eye Cohort Study was measured using the standard method. Sampling was done in 2009 using a random cluster approach. The prevalence of hypertension and pre-hypertension was determined by age and sex, and we used a multi-nominal logistic regression model to calculate the odds ratio (OR).
  
  
  RESULTS
  The prevalence of pre-hypertension was 37.2 % in men and 30.9 % in women, and the prevalence of hypertension was respectively 37.1 % and 39.0 %. In both sexes, there was an increase in the prevalence of hypertension and a decrease in the prevalence of pre-hypertension with age. Older age, male sex, higher body mass index, blood glucose higher than 140 mg/dl were found associated with hypertension and pre-hypertension. Also, diabetes increases the odds of hypertension (OR = 1.4) and a history of smoking was correlated with a decreased odds of having hypertension and pre-hypertension.
  
  
  CONCLUSIONS
  According to the criteria of Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure, the prevalence of hypertension and pre-hypertension was high in the studied population, and considering the epidemiologic transition of diseases in Iran, it can be concluded that a high percentage of the population are at risk of cardiovascular diseases.
