Objective: This study was aimed to investigate distribution of blood pressure (BP) and high BP related to risk factors. Methods: This study is a cross-sectional. Study was done among over 40 years aged men population in primary care centers of Eskişehir city center. Participants' were 2031 men. Study period was from 1 February to 30 March in 2005. Hypertension was defined according to the recommendations of the Seventh Report of the Joint National Committee (JNC 7). Data were analysed with SPSS for Windows software (version 11.5, Chicago, Il, USA). The Chi-square test, analysis of variance (ANOVA), and logistic regression analysis were used for statistical analyses. Results: The mean age participants was 61.73±10.24 (range 40-94) years. The mean systolic BP measurement was 135.79±23.41 mmHg and the mean diastolic BP measurement was 80.31±13.45 mm Hg for all participants. High BP was determined in 52.2%. Older age (p<0.001), family history of hypertension (p<0.05) and obesity (p<0.05) were important risk factors for hypertension. Conclusion: These results suggest that the measure of blood pressure over 40 years aged men population should be performed routinely in primary care centers in Eskişehir city center.
