Background: Racial/ethnic minority and immigrant groups individually experience lower rates of cervical cancer (CC) screening. Although immigrants represent large proportions of racial/ethnic minorities, few studies have explored the interacting health consequences of these social categories. Intersectionality is a theoretical framework which recognizes that studying social categories independently cannot capture their cumulative effects on health. In the context of CC screening, only one study took this approach but did not analyze several important barriers to care. This study aims to analyze the joint influence of race/ethnicity and immigrant status on screening and identify barriers unique to each intersectional group. Methods: Data from the National Health Interview Survey years 2005, 2010 and 2015 were drawn from IPUMS. Analyses were restricted to those eligible for CC screening (n=17,941). Multivariable logistic regression was used to model the interactional effect of race/ethnicity and immigrant status on screening up to date (UTD) status adjusting for confounders. Variables reflecting socioeconomic status (SES), access to care, acculturation and language were separately included to see whether they explained identified disparities. Finally, amongst women not UTD on screening, reasons for this were analyzed. All analyses were adjusted for complex survey design. Results: US born Non-Hispanic Black women had higher odds of being UTD on screening (OR 1.63, 95% CI [1.23, 2.18]) while immigrant Non-Hispanic White (OR 0.45 [0.29, 0.7]), immigrant Asian (OR 0.29 [0.2, 0.42]) and immigrant Hispanic/Latinx women (OR 0.51 [0.39, 0.67]) had lower odds compared to US born Non-Hispanic White women. Adjusting for SES (OR 0.87 [0.65, 1.16]) and access (OR 1 [0.74, 1.36]) attenuated the ORs for immigrant Hispanic/Latinx women but not immigrant Asian and White women. Adjusting for acculturation attenuated the ORs for immigrant Hispanic/Latinx (OR 0.84 [0.58, 1.22]) and White women (OR 0.68 [0.42, 1.12]) only. Adjusting for language increased but did not attenuate the ORs for all immigrant groups. Analyses of reasons for not screening showed immigrant Non-Hispanic White, Black and Asian women had greater proportions selecting “Didn’t need or know needed this test” versus other groups (10-12% vs. 5.4-8.4%). Conclusions: Immigrant status continues to explain much of the CC screening disparities previously attributed to race/ethnicity. SES and access to care remain important barriers for immigrant Hispanic/Latinx women but less so for other immigrant groups. This study reveals that acculturation is an important barrier for immigrant Non-Hispanic White and Hispanic/Latinx women, possibly representing disparities in knowledge. Language barriers may also contribute in all immigrant women. Further intersectional studies are needed to identify remaining barriers.
