Objective  To examine the awareness, treatment and control of hypertension and their influencing factors among hypertensive patients aged ≥ 40 years in rural regions of Liaoning province and to provide references for the prevention and control of hypertension.

  Methods  Using stratified random cluster sampling, we carried out a survey including questionnaire interview, physical examination and laboratory test among 10 926 permanent residents aged ≥ 40 years in 19 administrative villages of 4 counties, Liaoning province from September 2017 to May 2018. The awareness, treatment and control of hypertension and their correlates in 6 623 hypertensive patients identified from the participants of the survey were analyzed.

  Results  Among the 6 623 hypertensive patients, the crude and standardized rate were 47.50% and 44.25% for hypertension awareness, 35.41% and 31.34% for hypertension treatment, and 3.59% and 3.18% for hypertension control, respectively. Unconditional multivariate logistic regression analysis revealed that the patients with following characteristics were more likely to have higher hypertension awareness and treatment rate: female gender, aged ≥ 50 years, overweight/obesity, lack of physical exercise, family history of hypertension, history of diabetes, and high triglyceridemia; the patients with an average annual household income of 5 000 to 9 999 yuan RMB were more likely to have a high hypertension awareness rate; the patients with low serum high-density lipoprotein cholesterol were more likely to have a high hypertension treatment rate; the patients aged 50 – 69 years, lack of exercise, with family hypertension history were more likely to have a high hypertension control rate; whereas, the patients being current alcohol drinkers and with high serum total cholesterol were more likely to have low hypertension awareness, treatment and control rate; the patients with an average annual income of ≥ 20 000 yuan RMB were more likely to have a low hypertension control rate.

  Conclusion  The rate of hypertension awareness, treatment and control are low and the rates are associated with gender, age, average annual household income, current alcohol drinking, physical exercise, family history of hypertension, history of diabetes, overweight/obesity, high total cholesterol, high triglyceridemia, and low high-density lipoprotein cholesterol among hypertension patients aged 40 years and above in rural regions of Liaoning province.
