Migration and the risk of HIV infection: a review in Asia

Asia has populated with the second largest number of people living with HIV/AIDS. Under the advancement of transportation, the open up of borders between cities and countries, and the process of globalisation, people move from their place of origin to other places for better living conditions and employment opportunities. Mobile people and migrants are identified as the high risk population of HIV infection. Poverty, discrimination, limited access to healthcare and social services, separation with supports and families, being alienated in resident communities, and gender inequalities are the unfavourable conditions which make the migrant population vulnerable to HIV infection. Existing literatures have investigated and examined the potential risk factors among the mobile population. Inconsistencies were found among research but high risk sexual behaviours and poor knowledge and attitude were observed and reviewed within the migrants. However, literatures which compared the people who migrated with other local people in the same population were not yet reviewed systemically. Therefore, this paper aimed to review the articles which compare the migrant group and the non-migrant group in Asian population to identify the association between migration and the risks of HIV infection. A literature search of five databases (PubMed, Medline, Cochrane, CNKI, Wanfang Med Online) was performed and nine articles were eventually selected for review. The migration status of literature was studied as explanatory variable and compared across studies. Outcome variables of interest were grouped into four categories as: demographic characteristics, sexual practices, awareness towards HIV/AIDS, and disease prevalence. To conclude, compared to people who did not migrate, migrants in Asia were more tend to be less educated, have multiple sex partners, engage in high risk sexual intercourse and commercial sex, but their overall condom usage were lower. Also, they had higher risk of sexually transmitted infections and poorer knowledge in HIV/AIDS.published_or_final_versionPublic HealthMasterMaster of Public Healt
