Background
Age-dependent sex differences in hypertension control have been demonstrated in multiple populations. Four large primary care (PC) practices at Loyola adopted the Target:BP hypertension improvement program in 2018; hypertension control rates increased after adoption. Our study evaluated the impact of the Target:BP program on hypertension control by sex and by age group.
Methods
Analysis used data from 21,864 patients age ≥ 18 years with a hypertension diagnosis and > one outpatient visit in 2019 to a PC clinic enrolled in Target:BP program. Uncontrolled hypertension was defined as blood pressure ≥140/90 mmHg based on last visit. Mixed effects models were used to calculate adjusted odds of uncontrolled hypertension after adjustment for demographics and co-morbidities. Interaction term of sex* age group (≤ 65, 66-75, > 75 years) in fully adjusted mixed effects models was significant (P < 0.001) so adjusted odds of uncontrolled hypertension were calculated by sex and by age group. Adjusted proportion of patients with uncontrolled hypertension by sex and by age group was calculated using marginal effects.
Results
Mean age of patients with hypertension was 64.8 ± 12.7 years; 56.3% were female, 66.6% were White, 21.4% were Black and 11.0% were of Hispanic ethnicity. Among the 5973 (27.3%) with uncontrolled hypertension, 54.7% were female; mean age was 65.2 ± 12.9 years. Adjusted odds of uncontrolled hypertension was significantly higher among women vs. men age 66-75 years (OR 1.33; 95% CI 1.30, 2.28) and age 76+ years (OR 1.73; 95% CI 1.31, 2.28) vs. age ≤ 65 years. Figure 1 shows the adjusted proportion of patients with uncontrolled hypertension by sex and by age group.
Conclusion
Despite implementation of a hypertension improvement program, sex disparities in hypertension control persist among older adults.
