[Study on the epidemiological characteristics of work-related musculoskeletal disorders among 29 industries or occupational groups in China].

To analyze the distribution characteristics of work-related musculoskeletal disorders (WMSDs) among the occupational population in China's key industries during the period from 2018 to 2023, and to provide data support for the formulation of targeted prevention strategies. Between January 1, 2018, and December 31, 2023, a cross-sectional epidemiological survey and a retrospective investigation were conducted in seven geographical regions of North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China, using a combination of epidemiological cross-sectional and retrospective surveys. The industries were stratified according to the degree of closeness to WMSDs, the size of the occupational population, and the importance of the national economy, and then cluster sampling was conducted according to the size of the enterprises (large, medium, and small) within each stratum.

Comparing health-related quality of life of Dutch and Chinese patients with traumatic brain injury: do cultural differences play a role?

Background: There is growing interest in health related quality of life (HRQoL) as an outcome measure in international trials. However, there might be differences in the conceptualization of HRQoL across different socio-cultural groups. The objectives of current study were: (I) to compare HRQoL, measured with the short form (SF)-36 of Dutch and Chinese traumatic brain injury (TBI) patients 1 year after injury and; (II) to assess whether differences in SF-36 profiles could be explained by cultural differences in HRQoL conceptualization.

Gender differences in the pathways of family factors influencing children's oral health behaviours: a cross-sectional study of primary school students in Beijing, China.

Objective: Research on what family factors influence children's oral health behaviours (COHB) in developing countries is limited, and there have been no path analyses accounting for gender differences in these factors. Thus, our study evaluated gender differences in COHB including the influencing pathways of family factors in China.

Materials And Methods: Through multistage cluster sampling, 915 pairs of mothers and children from six public elementary schools in Beijing completed self-administered questionnaires regarding COHB, parents' modelling behaviours (PMB), parents' controlling behaviours (PCB), parents' oral health knowledge and attitudes (PKA), and children's oral health knowledge and attitudes (CKA).

Cardiovascular risk outcome and program evaluation of a cluster randomised controlled trial of a community-based, lay peer led program for people with diabetes.

Background: The 2013 Global Burden of Disease Study demonstrated the increasing burden of diabetes and the challenge it poses to the health systems of all countries. The chronic and complex nature of diabetes requires active self-management by patients in addition to clinical management in order to achieve optimal glycaemic control and appropriate use of available clinical services. This study is an evaluation of a "real world" peer support program aimed at improving the control and management of type 2 diabetes (T2DM) in Australia.

The Migrant Paradox in Children and the Role of Schools in Reducing Health Disparities: A Cross-Sectional Study of Migrant and Native Children in Beijing, China.

Migrants usually exhibit similar or better health outcomes than native-born populations despite facing socioeconomic disadvantages and barriers to healthcare use; this is known as the "migrant paradox." The migrant paradox among children is highly complex. This study explores whether the migrant paradox exists in the health of internal migrant children in China and the role of schools in reducing children's health disparities, using a multi-stage stratified cluster sampling method.
