Cumulative health disadvantages: an empirical study of the health and mobility of the first cohort of migrant workers in China

BackgroundThe study aimed to understand the factors affecting the health and healthcare of the first cohort of migrant workers in China using the concept of the cumulative disadvantage framework.MethodsData from the China Migrants Dynamic Survey (2017) were used to analyze the process of cumulative disadvantage of health and healthcare among migrant workers. The study also analyzed the spatial lag problem between localized medical insurance policies and healthcare accessibility.ResultsThe results revealed a significant negative association between the mobility of the first cohort of migrant workers and their health status. Long-term exposure to hazardous work had a greater negative impact on their health. Chinese migrant workers faced significant obstacles in accessing healthcare due to the lack of portability in health insurance.ConclusionThe study emphasizes the urgent need for addressing the structural barriers hindering healthcare access and outcomes for migrant workers. It is crucial to promote a more equitable and sustainable healthcare system in China to ensure migrant workers’ health and well-being

Migration and Health—Freedom of Movement and Social Benefits for Chinese Migrant Workers

This study utilized the concept of social right to understand factors affecting migrant workers’ health and healthcare in China. Using mixed methods, this study integrated findings from a survey of 817 migrant workers and a follow-up study of 30 intensive interviews to present an in-depth understanding of cumulative disadvantage of health and healthcare of rural-to-urban migrant workers. Our quantitative results indicated that migrant workers with no more than 5 years of working experience and having a good relationship with employers were 65% and 72.8% more likely to report good self-rated health as compared to their counterparts; those with work-related injury experience and low income were 41.6% and 53.6% less likely to report good self-rated health. Qualitative findings revealed the social contexts of the cumulative effect of the length of work experience and fear of medical cost on migrant workers’ declining health. Even though the participation rate for health insurance in China is reported to be over 99%, the lack of portability in health insurance and different reimbursement rates in health care access are structural barriers in health-seeking behaviors among Chinese migrant workers and in establishing sustainability in China’s healthcare system. This study adds to the literature by delineating the process of the unequal access to social rights in general, healthcare in particular as the major explanation for migrant workers’ poor health beyond the surface of China’s universal healthcare

Biodiesel production from mixed soybean oil and rapeseed oil

The biodiesel (fatty acid methyl esters, FAME) was prepared by transesterification of the mixed oil (soybean oil and rapeseed oil) with sodium hydroxide (NaOH) as catalyst. The effects of mole ratio of methanol to oil, reaction temperature, catalyst amount and reaction time on the yield were studied. In order to decrease the operational temperature, a co-solvent (hexane) was added into the reactants and the conversion efficiency of the reaction was improved. The optimal reaction conditions were obtained by this experiment: methanol/oil mole ratio 5.0:1, reaction temperature 55 °C, catalyst amount 0.8 wt.% and reaction time 2.0 h. Under the optimum conditions, a 94% yield of methyl esters was reached ~94%. The structure of the biodiesel was characterized by FT-IR spectroscopy. The sulfur content of biodiesel was determined by Inductively Coupled Plasma emission spectrometer (ICP), and the satisfied result was obtained. The properties of obtained biodiesel from mixed oil are close to commercial diesel fuel and is rated as a realistic fuel as an alternative to diesel. Production of biodiesel has positive impact on the utilization of agricultural and forestry products.Biodiesel Transesterification Soybean oil Rapeseed oil Co-solvent

Sexual Effect of Platelet-to-Lymphocyte Ratio in Predicting Cardiovascular Mortality of Peritoneal Dialysis Patients

Background. The study is aimed at exploring the relationship of platelet-to-lymphocyte (PLR), all-cause, and cardiovascular disease (CVD) mortality in peritoneal dialysis (PD) patients based on gender. Methods. A total of 1438 PD patients from January 1,2007 to December 31, 2014 in PD center at The First Affiliated Hospital, Sun Yat-sen University, were included. Patients were followed up until December 31, 2019. The endpoint was all-cause mortality and CVD mortality. Cox proportional hazards regression models were used to evaluate the association of PLR with all-cause and CVD mortality to calculate hazard ratios (HR) and 95% confidence intervals (CI). Results. After a median of 48.9 (interquartile range [IQR]: 23.4-79.3) months of follow-up, 406 (28.2%) patients died based on all-cause death, among which 200 (49.3%) patients died from CVD. In the multivariate Cox regression model, we found that PLR was independently related to an increased risk of CVD mortality only in female PD patients, with HR of 1.003 (95% CI: 1.001-1.006). Interaction test showed that the correlation between PLR level for all-cause and CVD mortality varied with gender (p=0.042 and p=0.012, respectively). Conclusion. Higher PLR was associated with a higher risk of CVD mortality in female PD patients
