Background: Disparities in cervical cancer (CC) screening exist within racial/ethnic minority and immigrant groups. However, few studies have explored the joint influence of race/ethnicity and immigrant status on screening, and the disparities that have been identified by existing studies remain incompletely explained. This study aims to identify the joint influence of race/ethnicity and immigrant status on CC screening and elucidate the barriers contributing to identified disparities. Methods: A cross-sectional analysis of 25,660 U.S. women from the 2005, 2010, and 2015 National Health Interview Surveys was done. The CC screening up-to-date status of cases was analyzed by race/ethnicity and immigrant status using logistic regression models. Conceptualized mediators were added to models to identify their contribution to identified disparities. Results: All immigrants had lower screening odds than U.S.-born non-Hispanic White women with foreign-born non-Hispanic Asians having the lowest odds (adjusted odds ratio [aOR]: 0.36, 95% confidence interval [CI]: 0.26-0.49) followed by foreign-born non-Hispanic White (aOR: 0.52, 95% CI: 0.36-0.76), Hispanic/Latinx (aOR: 0.58, 95% CI: 0.47-0.73), and non-Hispanic Black women (aOR: 0.62, 95% CI: 0.38-0.99). Adjusting for only socioeconomic status or access to care attenuated the aOR: for foreign-born Hispanic/Latinx and non-Hispanic Black women only. Adjusting simultaneously for language and acculturation attenuated the aOR: for all immigrants. Conclusions: Disparities in CC screening were only found in the immigrant populations of various racial/ethnic groups. Targeting insurance and health care access may address disparities in immigrant Hispanic/Latinx and non-Hispanic Black women. Focusing on culturally and linguistically competent care and education may be more crucial for immigrant non-Hispanic Asian and White women.
