Background: The association between different types of cities and the use of health services by aged migrant workers in China has not been widely reported in previous studies. This article aims to focus on rural-to-urban migrant workers in China aged 50 years and older to examine the relationship between the region of these migrant workers' destination city (eastern, central or western) and migration city type (first-tier, second-tier, third-tier and smaller cities) and their use of health services (e.g., establishing health records, participating in health education, and seeking medical treatment when ill).
Methods: This study's data were obtained from China Migrants Dynamic Survey in 2017. A total of 14,732 rural-to-urban migrant workers aged 50 years and older were included in the analysis; 6,938 of the migrant workers were either ill or had recently experienced physical discomfort. A chi-square test and binary logistic regression were performed to explore the associations between these rural-urban migrants' destination cities and their use of health services.
Results: This study found that aged rural migrant workers who moved to the east or to first- or second-tier cities were less likely to establish health records, participate in health education programme, and seek medical care.
Conclusions: Migrant destination cities are linked to the use of local health services by migrant workers aged 50 years and older in China. We found that aged migrant workers who migrated to relatively developed regions and cities accessed fewer health services. Such results signify that more attention should be paid to aged migrant workers' use of health services in economically developed regions and cities, to eliminate regional differences in healthcare inequality.
