Abstract

Cigarette smoking and hypertension are well known risk factors for cardiovascular disease, but the association between cigarette smoking and blood pressure/hypertension remains controversial. Although several existing studies have examined this association, their results are inconsistent. Therefore, this study is intended to examine the association between smoking and blood pressure/hypertension. This cross-sectional study was conducted in rural China. The study subjects were 575 volunteers with a mean age of 48.3 ± 5.6 years. They were divided into smokers and non-smokers. The effects of smoking on blood pressure and the prevalence of hypertension were examined. The results show that current smoking is associated with increased blood pressure and the prevalence of hypertension, but the associations are not statistically significant. After stratification by body mass index (BMI), smokers with BMI < 23 kg/m2 have a 3.717 mmHg increase in diastolic blood pressure as compared to non-smokers with BMI < 23 kg/m2 (p=0.017). Using non-smokers with BMI < 23 kg/m2 as a reference, smokers with BMI < 23 kg/m2 have a 4.712 mmHg increase in systolic blood pressure (p=0.034) and a 3.454 mmHg increase in diastolic blood pressure (p=0.011), non-smokers with BMI ≥ 23 kg/m2 have a 9.685 mmHg increase in systolic blood pressure (p
