In Yunnan’s border areas, there exists a population of female foreign migrants. Most of these women have migrated from border countries such as Vietnam, Myanmar, and Laos through marriage, but due to existing policies and institutional reasons, are not recognized as Chinese nationals. This presents them with problems when trying to use social security services, especially when it comes to accessing and using reproductive health services and other public health services. Based on the above, this study selected two representative areas of Yunnan, Honghe and Jinping County Dehong, for a case study of reproductive health services for Foreign wives. This research aims to analyze the causes of the current situation and propose solutions in order to implement evidence-based interventions in the future. This study implemented questionnaires, one-on-one in-depth interviews, group interviews, non-participant observation to collect the relevant information about RH services among the Foreign wives. The survey was given to a sample of 308 foreign wives, and 295 valid questionnaires were obtained. There were also 33 participants who completed qualitative interviews. Major Findings: 1. In these two areas, there was a rational allocation of human resources, technology, and a complete infrastructure to satisfy the reproductive health needs of the population. 2. This study found that the demand for reproductive health services amongst Foreign wives is diverse, urgent, and growing. 3. The study found other problems relating to the utilization of reproductive health services by Foreign wives, which include: a. Limited access to different sources of information b. The rate of prenatal care and hospital delivery rate amongst these women were relatively low compare to the Chinese resident in these areas. c. The utilization of reproductive health services by foreign women, in relation to when they arrived in China, shows that social integration levels affect utilization of health services. d. Maternity care costs are higher for Foreign wives, although most women have gained hospital reimbursement. This study suggests that the reasons for these problems are as follows: 1. There are language and cultural barriers, which result in difficulty when using local services. 2. The concepts around health service and skills held by service providers for foreign women are not enough, and ultimately lead to less use of services by these women. 3. The hukou registration system and lack of citizenship restrict foreign women from receiving equal access to services. 4. In addition, there is no uniform policy regarding health services for foreign women, leading to an unfair system.
