Screening for hepatitis B in the Bronx West African community with a blood pressure cuff: a cohort study

Background: Hepatitis B (HBV) and hypertension (HTN) are prevalent in West Africa (WA). Inadequate control is common, and evaluation and management are challenging among immigrants due to unfamiliarity with the United States (US) healthcare system. While HBV is stigmatised, HTN is recognised as an important condition. We describe how a HTN screening program can facilitate HBV screening in the Bronx WA community.

Methods: Thirty-minute HTN educational programs were delivered in collaboration with faith-based organisations, and 5-min presentations were presented upon request at community gatherings. Arrangements were made for those interested in a clinic visit where a questionnaire was completed, blood pressure (BP) measured, a free BP cuff provided, HBV testing performed, and referrals made. For those without ongoing care, insurance was arranged, and linkage to care provided.

Findings: Seven 30-min and five 5-min presentations were conducted. After the 30-min presentation, 204 of 445 attendees (45.8%) requested a visit, and 68 (33.3%) attended the visit. After the 5-min presentation, 80 requested a visit and 51 (63.8%) attended the visit. A BP >140/90 mmHg was present in 122 individuals (48.4%), including 43 (17.1%) without a history of HTN and 39 (15.5%) with BP >160/90 mmHg. All except two who reported previous testing agreed to HBV testing. 19 (7.5%) were hepatitis B surface antigen positive. Transition into ongoing care was provided for 60 (33.9%) with HTN who were not integrated into the US healthcare system.

Interpretation: HTN screening with a free BP cuff promotes HBV screening and US healthcare integration.
