Background Migrants account for a large part of China’s population. Many policies and inventions have been taken to improve access to public health services and the health of migrants. China’s Basic Public Health Services(BPHS) are a series of public health services in this policy domain, which aims at promoting the access of public health sevices and improve health equity of residents. The establishment of health records is the fundamental service of BPHS. However, there is little known about the establishment of health records among migrants in China, which hinders the more efficient provision of health services for migrants, and health equity is difficult to achieve. Based on the research gap, this study aims at showing the sociodemographic disparities in the establishment rate of health records, and identifying priorities and recommendations for promoting health equity of migrants in China. Methods This study used national data from China Migrants Dynamic Survey (CMDS) from 2014 to 2017 to evaluate the sociodemographic disparities in the establishment rate of health records and utilization of relevant public health services. The study included 539,926 respondents. Following the descriptive statistics of migrants, we showed the establishment rate of health records by sociodemographic characteristics and migrating related characteristics. Multivariate analysis was conducted to explore the associations between sociodemographic charicteristics, migrating related charicteristics and the establishment of health records. Results The establishment rate of health records among migrants in the sampled years were 22.99, 38.44, 27.29% respectively, and 29.18% in general, and there existed heterogeneity in the establishment rate of health records by sociodemographic charicteristics and migrating related charicteristics. Female migrants who were older, from middle age, married or living with partner, with higher educational attainment, with urban household registration, migrated for longer time, migrated for the reason of studying or family issues, migrated in province were more likely to establish health records. Conclusion There existed sociodemographic disparities in the establishment rate of health records and inequalities in the utilization of health records services among migrants in China. Migrating related characteristics also had impact on the establishment status. Policies should take both supply side and demand side of health services to improve the health equity of migrants, which means that relative departments should continue to invest in primary healthcare centers to improve their ability to provide services as well as migrants’ health literacy.

We aimed to assess the association between change in social participation and long‐term improved cognitive function among older adults. Data were obtained from 9648 participants aged ≥60 years in the 2011, 2014 and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey, a national prospective cohort study. Cox regression models were used to calculate adjusted risk ratios (aRRs). Social participation was increased in 20.5% of the participants, decreased in 37.8% of the participants and stable in 41.7% of the participants from the 2011 wave to the 2014–2018 waves. The improved cognitive function rate was 17.9% at follow‐up. Compared to individuals with decreased social participation from the 2011 wave to the 2014–2018 waves, individuals with unchanged total social participation were 59% (aRR = 1.59, 95% CI: 1.35–1.87) more likely to have improved cognitive function in the 2014–2018 waves, and individuals with increased social participation were 61% (aRR = 1.61, 95% CI: 1.43–1.82) more likely to have improved cognitive function, regardless of the baseline social participation status. As for the three forms of social participation, compared with the participants with decreased social participation, those with increased participation in organised social activities, increased participation in group leisure‐time activities, unchanged informal social interactions and increased informal social interactions were 24% (aRR = 1.24, 95% CI: 1.02–1.51), 49% (aRR = 1.49, 95% CI: 1.21–1.84), 55% (aRR = 1.55, 95% CI: 1.37–1.76) and 57% (aRR = 1.57, 95% CI: 1.34–1.84) more likely to have improved cognitive function (all p < 0.05) respectively. The results were stable in the sensitivity analysis. Our findings highlight the importance of promoting social participation from a multidimensional perspective (duration, frequency and forms) to improve cognitive function among older adults, for policy makers and healthcare workers in the community.

Cross-sectional studies about the association between social integration, social exclusion, and vaccination behavior among internal migrants in China are lacking. In this study, we aimed to explore the association between the influenza vaccination behavior and social integration as well as social exclusion in China based on a cross-sectional study. We included 12,467 participants aged 15 years old or above from the 2017 Migrant Population Dynamic Monitoring Survey (MDMS). We used univariate analysis and logistic regression models to access the association between social integration, exclusion status, and influenza vaccination rates. Results suggested that the association between social integration and the vaccination rate was significantly positive. Moving between different districts impact on people’s mental health and their health performance. Significant association between influenza vaccination behavior and education attainment, income status, health record, and awareness of basic public health services program was reported. Therefore, in order to reduce the incidence of influenza disease and increase the vaccination rate, policymakers and the public should promote social integration for internal migrants. Meanwhile, our finding also implies possible strategies to promote COVID-19 vaccination.

Introduction China has implemented Basic Public Health Service (BPHS) in 2009, aiming to improve the health status of the people, and the content of service includes implying health education for residents. As an important group of people, the migrants can easily become main reason for major infectious diseases such as HIV between different provinces, but the effect of receiving health education is still unknown for migrants. Therefore, the health education of China’s migrant population has received widespread attention. Methods This study used the data of the China Migrants Dynamic Survey (CMDS) from 2009 to 2017, and evaluated the trend of HIV health education acceptance rate of different migrant groups across the country (n = 570,614). Logistic regression model was used to test the influencing factors of HIV health education rate. Results: The study found that the overall HIV health education rate of Chinese migrants decreased from 2009 to 2017, and different types of migrants showed different trends. The proportion of migrants aged 20–35 who receive education fluctuates, and ethnic minorities, western regions, and migrants with high education were more likely to receive HIV health education. Conclusion: These findings identify when implementing health education for migrants, we can carry out more education for specific groups to promote the health equity of the migrant population.
