Abstract

Objective: Previous studies of disparities in breast and cervical cancer screenings have focused on broad racial/ethnic groups or nativity status without accounting for immigration histories. Recent theoretical work argues for using intersectional approaches and examining within-group inequalities. Utilizing multiple years of National Health Interview Survey (NHIS) data, we examined between- and within-group Papanicolaou (Pap) test and mammogram screening based on nativity and length of U.S. residence for Asian and Hispanic women, along with non-Hispanic Black and White women.

Design: The study samples consist of 54,900 women ages 21-64 without a hysterectomy who responded to questions about Pap test screening and 36,300 women ages 40-64 who responded to questions about mammogram screening. Asian and Hispanic women were further stratified by nativity and, for immigrants, length of time in the United States. Logistic regression analysis was used to identify significant associations with Pap test and mammogram screenings.

Results: Recent Asian and Hispanic immigrants had the lowest Pap test and mammogram rates among all other groups, while Black (and White women for mammograms) women had the highest rates. After accounting for age, marital status, health insurance, education, employment status, and income, both Asian groups had lower odds, and Black and all Hispanic groups had higher odds of Pap test screening compared with White women. Similar results were observed for mammogram screening, except that long-term immigrant/U.S.-born Asian and U.S.-born Hispanic women did not have significantly different odds compared with White women. In general, the strength and direction of most sociodemographic variables were similar across groups for Pap test screening but differed for mammogram screening.

Conclusions: The between-group differences identified emphasize the disparities in screening between racial/ethnic groups while the within-group differences suggest the need to examine whether more targeted outreach efforts and prevention messages can increase screening for specific groups.
