ABSTRACT
Objective To determine the awareness, treatment and control of hypertension and its determinants in the elderly hypertensive patients of Dean nationality so as to explore the associated determinants. Methods This was a cross-sectional, population-based survey. A total of 939 persons aged 60 years and older sampled by stratified sampling method from the elderly population of Dean nationality were examined from July to September 2016. Meanwhile, the data of medical history and examination were collected. Results There were 353 elderly patients with hypertension in the 939 subjects. The awareness, treatment and control of hypertension in the elderly hypertensive patients (EHP), which was 47.3％, 36.5％and 22.1％respectively, were higher than the results of previous national study and had the upward trends with the increasing age (<0.05) . In comparison with the reference group, EHP living in middle economic level area had the higher awareness, treatment and control of hypertension (<0.05) . The results of covariate-adjusted multilevel logistic regression model indicated that there was a cross-level interaction effect between middle economic level area and dyslipidemia on the awareness and treatment of hypertension respectively, and a cross-level interaction effect between middle economic level area and low fat diet on the control of hypertension ( <0.05) . The individual level covariates, age (OR=1.3412, 1.3144, 95％ CI 1.0217-1.7609, 1.0030-1.7225) and diabetes ( OR=2.6735, 2.3078, 95％ CI 1.0721-6.6672, 1.0240-5.2007), had the positive association with the awareness and treatment of hypertension;age (OR=1.4740, 95％CI 1.0034-2.1654), non-drinking (OR=3.2056, 95％CI 1.5554-6.6066) and low salt diet (OR=3.6969, 95％CI 1.7996-7.5946) had the positive association with the control of hypertension. Conclusion The awareness, treatment and control of hypertension in the EHP of Dean nationality were higher than those of the national level, and the dominant factors were economic level, age, dyslipidemia, diabetes, non-drinking, low fat diet and low salt diet, etc.
