The study objective was to examine factors associated with previous hepatitis B virus (HBV) testing among Vietnamese women. A population-based survey was conducted in Seattle. The survey was completed by 370 women (response rate: 82%). Sixty-eight percent of the respondents reported previous HBV testing. Only 44% recalled a physician recommendation for the test. The following factors were associated with previous testing in bivariate comparisons: knowing that HBV can be spread during childbirth, during sexual intercourse, and by sharing toothbrushes; doctor(s) had recommended testing; family member(s) and friend(s) had suggested testing; and family member(s) were chronically infected with HBV. In a multiple regression analysis, women who reported a previous physician recommendation had nearly a five times higher odds of testing than those who did not. Education about HBV transmission may stimulate Vietnamese women to seek testing. Intervention strategies that target social networks might be effective in increasing testing levels. Physicians should be educated about the importance of testing Asian immigrants for HBV.
