Abstract: Objective　To examine the relationship between high blood pressure and body mass index（BMI）among 18-74 years old residents in Henan Province.Methods　Cross-sectional survey was conducted by using multi stage stratified random sampling method in all counties of Henan Province from April to July in 2012.The total number of designed respondents was 18 000.The face-to-face investigation mainly included basic characteristics （gender，age，education level，occupation and income），lifestyles（smoking，drinking history） and physical measurement （height，weight，waist circumference，hip circumference and blood pressure）．Results　18 842 were actually surveyed.The effective sample was 16 801 and the effective rate was 89.17% in this investigation.The hypertension prevalence was 27.63%（4 642/16 801），the incidence of hypertension in male was 29.90%（2 218/7 419）and 25.84% （2 424/9 382） in female.The awareness and treatment rate were 42.40% （1 968/4 642），35.95% （1 669/4 642）respectively，the control rate was only 11.44%（531/4 642）．Drawings fouding，systolic and diastolic blood pressure were increased with the increase of BMI in both genders.The correlation analysis showed that，BMI was positively correlated with systolic and diastolic blood pressure after the gender and age were adjusted，and the corresponding partial correlation coefficient were 0.230 and 0.325 （P<0.001）respectively.Multiple linear regression showed that BMI had influences on blood pressure of residents with different gender，age，education level，occupation，income smoking，drinking history and central obesity.Conclusion　The prevalence rate of hypertension in Henan was high，with a low blood pressure control rate，however.The blood pressure was closely related to BMI，so we should focus on strengthening the prevention and control measures of the overweight and obese people.
