Objectives - The objective of this study was to compare cervical cancer screening practices using Pap smears among French women born to two French parents (FPF), French women born to at least one foreign parent (FPE), and foreign women in the Paris metropolitan area. Methods - The data come from the second wave of the "Health, Inequalities, Social Disparities" (SIRS) cohort survey, conducted in 2010 among a representative sample of French-speaking adults in the Paris metropolitan area (1,724 women). Logistic regression models analyzed the demographic, socioeconomic, social integration, and health characteristics associated with a lifetime absence of FCU. Results - Among women aged 25 or older, 91.2% had already had at least one FCU in their lifetime. After adjusting for age, FPE women were twice as likely to have never been screened as FPF women (OR=2.46; 95% CI [1.60–3.77]), and this risk doubled for foreign women (OR=5.27; 95% CI [3.41–8.15]). The proportion of life spent in metropolitan France reduced the risk of not being screened for foreign women, but the differences between FPF and FPE women or foreign women persisted, even when all other characteristics were taken into account. Conclusion - Specific actions must be taken to reduce immigration-related inequalities in cervical cancer screening. (R.A.)
