Prevalence and Factors Associated to Hypertension Among Older Adults in Bogota, Colombia

Objective: To characterize older adults in Bogota with high blood pressure and identify factors associated to this condition within this population. Method: Using data from the Salud, Bienestar y Envejecimiento (SABE) (Health, Well-being and Aging) Bogota Study, we analyzed community-dwelling adults 60 years and older with hypertension. We estimated the prevalence and used logistic regression models to identify factors associated to hypertension. Results: The overall prevalence for hypertension was 56.9%. Older age (odds ratio [OR] = 1.46, 95% confidence interval [CI] = [1.07, 1.97]), having health insurance (OR = 4.15, CI = [1.95, 8.85]), cardiovascular diseases (ORs between 1.70 and 3.65), and poor self-rated health (OR = 1.57, CI = [1.20,2.06]) significantly increased the odds of hypertension. Most individuals received pharmacologic treatment (93.5%); however, 28.4% of individuals had uncontrolled hypertension. Discussion: We found a high prevalence of hypertension in our cohort and found that comorbidities and poor self-rated health increase the odds of hypertension. Future studies need to tailor interventions for hypertension management in old age.
