Abbreviation: aOR Adjusted odds ratio, CI confidence interval, RV Rubella virus, IgG Immunoglobulin G
^a Separate models of all migrant women compared to native women; inter-provincial migrant women and intra-provincial migrant women compared to native women; migrant women with migrant spouses and migrant women with native spouses compared to native women were constructed
^b Adjusted ORs were calculated by multivariate logistic regression after adjusting for age, ethnicity, educational attainment, occupation, residential address, and study year
^c Anti-RV IgG + by natural infection was conducted among women who reported not having RV vaccination
