Association between blood pressure control and risk factor in community hypertensive patients

Objective To investigate the rate of blood pressure control and its influencing factors in hypertensive patients and to provide evidence for hypertension control. Methods A total of 28 518 adults(≥18 years old)were selected with multi-stage randomized sampling and surveyed with a questionnaine. Results The prevalence of hypertension was 27.52%.The rate of having anti-hypertension medication routinely among the hypertensive patients was 51.51% and the rate of blood pressure control was 26.77%.For the 4 042 hypertensive patients,the rate of blood pressure control in the male was lower than that in the female(25.51% vs 27.75%)with a significant difference(χ²=292.031,P=0.000);the rates of blood pressure control among the patients of 18-44,45-59,60-74,and≥75 years old were 20.51%,24.09%, 29.00%,and 28.12%,respectively,with significant differences among the different age groups(χ²=65.880,P=0.000). The results of principal component logistic regression analyses showed that high-salt food(>6 g/d),smoking and alcohol consumption were associated with the uncontrolled blood pressure. Conclusion Smoking cessation,reduction of alcohol consumption and lowering sodium intake are likely beneficial to blood pressure control for hypertensive patients.
