Migrant health has been identified as one of the most pressing issues of the 21st century. Migration experiences are influenced by gender and gender norms and have important implications for the sexual health of migrant women. This systematic review explored socioecological factors influencing sexual health experiences and health outcomes of migrant Asian women living in "Western" high-income countries. PRISMA guidelines were followed and this study was registered with PROSPERO. Five academic databases were searched for peer-reviewed articles published between 2000 and 2019. Of 2415 studies retrieved, 17 met the selection criteria: 12 qualitative, 4 quantitative, and 1 mixed-methods study. The four levels of Bronfenbrenner's socioecological model were applied to examine the individual, interpersonal, institutional, and societal factors of influence. Most studies (n = 13) reported individual level factors, focusing on knowledge and use of contraceptives. At a societal level, host country sociocultural factors, including gender and cultural norms, influenced knowledge, ability to access and utilise contraceptives, and access to health services. Findings suggest that the public health policy, practice, and research to improve the sexual health of migrant women requires greater consideration of the intersecting factors of gender, culture, and the migration process.
