Abstract
ObjectivesThe 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.MethodsRespondent-Driven Sampling (RDS) approach was used to recruit migrants in Chengdu city from September 2008 to July 2009. All migrants’ residences were geo-coded on the map. Hepatitis B Vaccination serves as a surrogate for the Health protection status. Logistic regression was used to explore the association between independent variables and the Hepatitis B vaccination status. Spatial scan statistics were used to explore the spatial pattern of the Hepatitis B vaccination status.ResultsAmong the 1045 rural-to-urban migrants, higher education, better employment condition and post-80 generation are positively associated with the Hepatitis B vaccination status, while marriage status, the insurance status and the income are not. The spatial scan statistics identified three spatial clusters of low vaccination rate. Two of them were in urban villages and the other was a declining workers’ community.ConclusionsThe migrant population is heterogeneous, and the post-80 generation migrants get more health protection. Spatial analytical techniques illustrated clusters of low vaccination rate are highly linked with pre-1980 generation migrants and other socioeconomic factors, especially the employment condition. Such information might shed light on the differences and needs across migrant subgroups and may be useful for developing more targeted health policies for Chinese migrants.

Statistical methods Two statistical methods were used in this study to investigate Hepatitis B vaccination status: Descriptive analysis was conducted to examine the frequency distribution and the odds ratio for the categorical variables, or mean values and standard deviations for the continuous variables

Summary
The scale of world migration has expanded remarkably over the past decades. As a result, population mobility becomes one of the leading global policy issues for the 21st century [1]. Since the economic reforms of China in 1978, a growing number of rural populations are working in urban area [2]. The volume of rural-to-urban migrants has increased dramatically in China with the rapid economic growth for the past 30 years, and it amounts to around 260 million migrants according to the 2010 national census. The continuing trend of rural to urban migration leads great attentions to health issues of the migrants in research with most existing studies focused on the risks of diseases and the access to health service. Several studies found that migrants lack the knowledge of HIV and are more likely to be engaged in risk behaviors, such as casual sex without using condoms [3,4]. For the access to the health services, studies found that
