Abstract

Prevalence and Factors Associated with a 10-year Cardiovascular Risk among Elderly with Hypertension in Northern Rural Thailand

Objective: The purpose of this study was to investigate the prevalence and factors associated with the 10-year cardiovascular risk level among elderly with hypertension patients. Method: A community-based analytical crosssectional study was carried out on 615 samples drawn in Chiang-Rai Province, Northern Region, and Thailand from December 2018-July 2019 through a multistage random sampling technique consisting of a cluster, proportional and systematic random sampling technique. A binary logistic regression was used for the univariate and multivariate analyses to investigate factors associated with cardiovascular risk. Result: A total of 615 elderly with hypertension were recruited into the study, of which 59.20 were female. The average age was 67.16, 43.70% had a family history with hypertension, 22% with diabetes. The prevalence of a 10-year Cardiovascular Disease (CVD) risk of elderly with hypertension was high-risk level about 30.90%. Factors associated with CVD risk were 70-79 groups of age (AOR=6.34, 95%CI=3.56-11.32), male (AOR=2.78, 95%CI=1.49-5.18), with diabetes (AOR=5.12, 95%CI=2.87- 9.14), Systolic Blood Pressure (SBP) (AOR=1.09, 95%CI=1.07-1.11), High-Density Lipoprotein (HDL) (AOR=0.91, 95%CI=0.89-0.94), and current smoking (AOR=5.37, 95%CI=2.40-11.98). Conclusion: The primary prevention and control of CVD recommended for elderly with hypertension patients to identify high-risk individuals’ factors concerned are in middle older age, male, with diabetes and smoker, especially the intervention program should be promoted to reduce High-Density Lipoprotein (HDL) cholesterol
