The purpose of this research is to empirically test the salmon bias hypothesis, which states that the "healthy migrant" effect-referring to a situation in which migrants enjoy lower mortality risks than natives-is caused by selective return-migration of the weak, sick, and elderly. Using a unique longitudinal micro-level database-the Historical Sample of the Netherlands-we tracked the life cour...

Because of China's increasing industrialization over the past two decades, many rural residents have migrated to urban areas but frequently return to visit their home villages. These rural-to-urban migrants are generally young, are better educated than non-migrating rural residents but less educated than their urban counterparts, are most likely employed in venues such as construction sites, fa...

BACKGROUND In the last few years, Malta has witnessed increasing immigration flows from the Libyan coasts. Public health policies are focused on screening migrants for tuberculosis, whereas no systematic actions against STIs are implemented. The aim of this study is to define the epidemiological profile of asylum seekers in Malta as regards syphilis, hepatitis B, C and latent tuberculosis, thus...

OBJECTIVES The objectives of this study were to investigate differences on health protection status between two generations (born pre- vs. post- 1980) of rural-to-urban migrants in China, and whether the differences are associated with spatial contexts. METHODS Respondent-Driven Sampling (RDS) approach was used to recruit migrants in Chengdu city from September 2008 to July 2009. All migrants...

BACKGROUND It has been frequently reported a higher incidence of psychotic disorders in immigrants than in native populations. There is, however, a lack of knowledge about risk factors which may explain this phenomenon. A better understanding of the causes of psychosis among first-generation migrants is highly needed, particularly in Italy, a country with a recent massive migration. METHODS/D...

Previous research suggests that Mexican female migrants face more barriers than their male counterparts. However, few studies examine how the educational characteristics of female migrants differ from those of male migrants and how selectivity may have changed in the context of evolving gender dynamics in both countries. This study uses U.S. and Mexican census data from 1960 to 2000 to compare ...

We examined migration in China using the 2005 inter-census population survey, in which migrants were registered at both their place of original (hukou) residence and at their destination. We find evidence that the estimated number of internal migrants in China is extremely sensitive to the enumeration method. We estimate that the traditional destination-based survey method fails to account for ...

This study focuses on Wenzhou migrants and explains the developmental path of overseas migrants’ sustained entrepreneurship. It also analyzes how migrant entrepreneurs fit into the Italian culture to improve ambidextrous innovation ability. This paper applies the methods of induction and longitudinal study, conducts case studies on four migrant entrepreneurs, and explores embedding strategies i...

BACKGROUND Preventive health services (PHSs) form part of primary healthcare with the aim of screening to prevent disease. Migrants show significant differences in lifestyle, health beliefs and risk factors compared with the native populations. This can have a significant impact on migrants' access to health systems and participation in prevention programmes. Even in countries with widely acces...

BACKGROUND Prevalence of infectious diseases in migrant populations has been addressed in numerous studies. However, information is sparse on their mortality due to chronic diseases that are aetiologically associated with an infectious agent. This study investigates mortality related to infectious diseases with a specific focus on cancers of possibly infectious origin in voluntary migrants from...
