Noah AJ - Researchers used the 2014–2015 US birth rate population data to assess the links between individual-level correlates and hepatitis B virus infection among Asian American and Pacific Islander pregnant women by using a series of logistic regression models. The prevalence of hepatitis B virus infection was investigated. Hepatitis B virus infection was 10 times more likely to develop among Chinese American mothers vs Asian Indian and Japanese American mothers, among Asian American and Pacific Islander pregnant women. Foreign-born mothers are significantly more likely to have hepatitis B virus infection during pregnancy than their U.S.-born counterparts. Overall, careful consideration of ethnicity in conjunction with group-specific factors are important in the light of heterogeneous prevalence of hepatitis B virus infection among Asian American and Pacific Islander pregnant women.
