Abstract：Objective To investigate the hypertensive prevalence in smoking population in Gansu Province from 2013 to 2014.Methods The population was sampled according to principle of multi-stage stratified cluster sampling, and then the samples were given questionnaire, physical examinations and blood pressure measurements. Results There were totally 15430 cases involved in the survey and 3993 hypertensive patients, and hypertension prevalence was 25.88%. The difference in hypertension prevalence had no statistical significance between male and female patients (P>0.05). There were totally 11758 non-smokers and hypertension prevalence was 24.79% among them. There were 3003 daily smokers and hypertension prevalence was 30.57% among them. There were 669 occasional smokers and hypertension prevalence was 23.92% among them. The hypertension prevalence was higher in daily smokers than that in non-smokers and occasional smokers (allP<0.05). The hypertension prevalence was 17.98% in smokers smoked for less than 6 m, 20.51% in smokers smoked from 6 to 12 m, and 30.35% in smokers smoked for more than 1 y. The hypertension prevalence was higher in smokers smoked for more than 1 y than that in smokers smoked for less than 6 m (P<0.05). The age of starting smoking [(25.03±9.06) yvs. (22.93±6.71) y], cumulative smoking time [(29.34±14.36) yvs.(19.97±14.35) y] and time of exposure to secondhand smoke [(5.23 ±2.21) yvs. (4.49±2.38) y] were higher in hypertensive patients than those in normal population (allP<0.05). Conclusion The hypertension prevalence is higher in the population with higher smoking frequency and longer duration in Gansu Province, and it is necessary to strengthen smoking control and intervention.
