Migration-related changes in smoking among non-Western immigrants in France

Résumé 0

Background Migrants make up a growing share of European populations, and very little is known about the impact of migration on their smoking patterns. We develop a longitudinal analysis of smoking prevalence among native-born and immigrants in France based on retrospective data collected in the 2010 national Baromètre santé health survey. Methods Analyses concerned 19 578 individuals aged 18–70 years and born in metropolitan France, in the Maghreb or in sub-Saharan Africa. Person-years with and without smoking were reconstructed using migration and smoking histories and analyzed with discrete-time regression models. Results Prior to migration, immigrants from both the Maghreb and sub-Saharan Africa had lower smoking prevalence than the native-born of similar birth cohort, age and education. After migration, the prevalence increased over time among Maghrebin men up to levels beyond those of the native-born (odds ratio: 1.54 [1.09–2.17] for 10 years of residence or more), while it remained much lower throughout among men from sub-Saharan Africa (odds ratio: 0.36 [0.19–0.68] for 10 years of residence or more). Starting at extremely low levels, the prevalence in both groups of women rose considerably after migration. Women from sub-Saharan Africa nearly caught up to the native-born (odds ratio: 0.70 [0.37–1.32] for 10 years of residence or more), but this was not the case for those from the Maghreb (odds ratio: 0.52 [0.33–0.81] for 10 years of residence or more). Conclusion The findings uncover the low pre-migration prevalence and the diversity of post-migration trajectories. Tobacco control programs targeting recently arrived migrants would contribute to prevent unhealthy assimilation.
