Background:
Hypertension (HTN) is the most potent cardiovascular disease worldwide and a major public health concern in the U.S. Although Social Determinants of Health (SDoH) are associated with HTN, it is unclear whether these indicators are routinely captured in the primary care setting. We sought to examine the prevalence of any HTN and its association with captured SDoH for new patients (pts) presenting to an urban community primary care clinic for 2019 and 2020.
Methods and Results:
We identified a cohort-based, cross-sectional sample of 2,577 new pts ≥ 18 years of age in a community clinic in Atlanta, GA, between Jan 2019 and Dec 2020. Electronic health records were reviewed to determine the rate of selected SDoH indicators (financial strain, transportation, medical transportation, and food insecurity) captured at any time and the presenting blood pressure for all new patients. Blood pressure was classified as follows: normal, systolic BP/diastolic BP (SBP/DBP) ≤120/80 mmHg, elevated SBP 120-129mmHg and DBP<80mm, stage 1 SBP 130-139mmHg or DBP 80-90mmHg, and stage 2 SBP ≥ 140mmHg+ or DBP 90mmHg+. Likelihood-ratio Chi-square tests were analyzed to detect an association between SDOH and stages of HTN. Of the 2,577 pts seen, 93% were African American, 72% were female, 59% were single, 77% had BMI ≥ 25, and 85% were insured. Only 41% (n=1062) pts had information of at least one SDoH measure in the entire cohort. Of the SDoH domains evaluated, financial strain and food insecurity were more likely in new pts with stage 1 HTN or higher (χ2= 16.0, df=8, p=0.04; χ2= 27.7, df=12, p=0.006).
Conclusion:
Routine assessments of SDoH for African American pts presenting for new pt visits are suboptimal in the primary care setting. However, financial strain and food insecurity are significantly associated with stage 1 and 2 HTN in this population. Standardization of intake processes is essential to increase the collection of SDoH indicators and may ultimately guide secondary prevention strategies for HTN interventions.
