Objective:To analyze and evaluate the equity of children's health in countries along the"the Belt and Road",promote further attention to children's health in countries along the route,and promote cooperation and exchanges on children's health between China and countries along the"the Belt and Road".Methods:Using concentration index and concentration curve to measure overall equity,and using the Thiel index for intraregional and interregional euqity measurement.Results:The under-five mortality concentration index is 0.349 7,the concentration curve is below the absolute fair line.The Thiel index shows that inequality in low-income countries,lower-middle-income countries,upper-middle-income countries and high-income countries is the leading cause of child health inequities in the"the Belt and Road"countries.Conclusion:There is inequity in the health of children in countries along"the Belt and Road Initiative",countries along the"the Belt and Road"should take comprehensive measures to reduce the under-five mortality rate,at the same time strengthen international cooperation to further promote equity in children's health in"Belt and Road"countries.

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

Objective To quantitatively analyze and evaluate the content of rehabilitation policy for people with disabilities in China. Methods This study focused on ten national policies of disability rehabilitation issued from 2021 to 2023.It employed text mining techniques to process policy texts and constructed a policy modeling consistency index model for dis-ability rehabilitation policies in China.The relevant policies were evaluated and analyzed quantitatively. Results The disability rehabilitation policies in China were relatively comprehensive in terms of policy transparency,op-erational mechanisms and policy nature.However,there was still a need for optimization in terms of policy per-spectives,target groups,incentive mechanisms,and other aspects. Conclusion The overall quality of disability rehabilitation policy texts at the national level in China is relatively good.There is a need to further enhance the predictability of policy objectives,clarify the responsibilities and division of labor among various departments,and improve policy incentive mechanisms in future policy formulation,which will further refine China's disability rehabilitation policy system and contribute to high-quality develop-ment of the disability cause.
