Risk factors and its quantitative evaluation for hypertension in urban area of Qingdao

Objective To investigate the related risk factors for hypertension among residents in urban area of Qingdao, and perform quantitative evaluation analysis on the risk factors. Methods We analyzed the baseline data of participants who were aged 30-79 years and had been enrolled into the CKB study from Qingdao City. Multivariate Logistic regression model was used to analyze the risk factors of hypertension, and the risk scores and individual risk were calculated. Results A total of 35 509 participants were investigated in the baseline survey. Ratio of male to female was 1 • 1. 27, and the average age was (50. 32±10. 18) years. The prevalence of hypertension in residents aged 30-79 years old in urban area of Qingdao was 36. 55%. Multivariate Logistic regression analysis showed that older, low family income, frequent drinking, infrequent consumption of fruit, excessive BMI, and large waist-to-hip ratio were risk factors for male hypertension, and higher risk factors (excluding age) were BMI^28.0 kg/m2 (OR = 3. 42), frequent drinking (OR =1.41), and waist-to-hip ratio ^0. 9 (OR = 1. 37). Older, infrequent consumption of fruit, excessive BMI, and large waist-to-hip ratio were risk factors for female hypertension. The OR values of BMI^28.0 kg/m2, waist-to-hip ratio^0.85, and infrequent consumption of fruit were 3. 11, 1.46, and 1.28, respectively. Conclusions Higher BMI, frequent drinking, and large waist-to-hip ratio were main risk factors for hypertension in male residents in Qingdao City. Higher BMI, large waist-to-hip ratio and infrequent consumption of fruit were main risk factors for hypertension in female residents. Community health education and follow-up intervention should be carried out in accordance with the characteristics of risk factors for hypertension in different populations.
