To measure disparities in hepatitis B virus (HBV) infection and immunity among a high-risk patient population at a community health center in New York City. <\/jats:p><jats:p> Methods. We performed a retrospective chart review of 25\u2009565 adults with HBV surface antigen, surface antibody, and total core antibody tests from 1997 to 2017. We categorized HBV test results by infection and immunity status and analyzed by demographic characteristics with \u03c7<jats:sup>2<\/jats:sup> and logistic regression analysis. <\/jats:p><jats:p> Results. Of 25\u2009565 adults, 13.4% were currently infected, 52.1% were ever infected, 33.4% were immune from vaccination, and 14.5% were susceptible. Significant factors associated with ever infection were age, male sex, being China-born, limited English proficiency, having Medicaid or no insurance, and family history of HBV (P\u2009&lt;\u2009.01). <\/jats:p><jats:p> Conclusions. Our study demonstrated a high burden of HBV infection among foreign-born Asian Americans seeking care at a community health center. <\/jats:p><jats:p> Public Health Implications. It is important to test patients at high risk for HBV infection with all 3 tests to identify those with current infection, risk for reactivation, or need for vaccination, and to assess the effectiveness of public health interventions. <\/jats:p>","DOI":"10.2105\/ajph.2018.304504","type":"journal-article","created":{"date-parts":[[2018,11,1]],"date-time":"2018-11-01T20:50:48Z","timestamp":1541105448000},"page":"S327-S335","source":"Crossref","is-referenced-by-count":12,"title":["Disparities in Hepatitis B Virus Infection and Immunity Among New York City Asian American Patients, 1997 to 2017"],"prefix":"10.2105","volume":"108","author":[{"given":"Amy S.","family":"Tang","sequence":"first","affiliation":[{"name":"Amy S.
