To explore the status and influencing factors of health poverty among the elderly in rural areas of Sichuan in the post poverty alleviation era.

By using the method of multi-stage sampling, a questionnaire survey was conducted among 606 rural elderly persons in Sichuan from July to August, 2022. Chi-square test and multivariate logistic regression analysis were used to explore the influencing factors of health poverty.

Among the 606 persons, 167 (27.6%) were in health poverty.The results of multivariate analysis showed that age(OR=1.655, 95%CI: 1.250-2.191), number of chronic diseases (OR=1.864, 95%CI: 1.510-2.301) and physical function limitation (OR=1.890, 95%CI: 1.353-2.640) were the risk factors, while the number of daughters (OR=0.739, 95%CI:0.593-0.920) and labor intensity in the past year (OR=0.498, 95%CI: 0.343-0.722) were protective factors for health poverty in the rural elderly.

The rural elderly in Sichuan still have a high risk of health poverty, especially the elderly who are aged, suffer from multiple chronic diseases, have serious disability, have little labor intensity, and have few daughters are the high-risk groups of health poverty, which needs to be paid attention to.

To explore the relationship and mechanism of stress perception and loneliness among emotional intelligence and life satisfaction among master’s students, and to provide reference basis for promoting the mental health development of graduate students.

A total of 728 graduate students from 6 universities were selected by stratified cluster random sampling and investigated by emotional intelligence, loneliness, stress perception and life satisfaction scale. SPSS 25.0 was used to conduct independent sample t-tests, analysis of ANOVA, and Pearson correlation analysis on the data. A structural equation model was bulit by using AMOS 26.0 software and evaluated.

Emotional intelligence was positively correlated with life satisfaction (r=0.423, P<0.01). There was a negative correlation between perceived stress and loneliness, life satisfaction, and emotional intelligence (r=-0.519, -0.440, -0.536, -0.505,P<0.01). There was a positive correlation between perceived stress and loneliness (r=0.568, P<0.01). Emotional intelligence can not only directly predict life satisfaction, but also indirectly through stress perception and loneliness. The mediation effect value of stress perception was 0.227 accounting for 42.5% of the total effect,and the mediation effect value of loneliness was 0.026, accounting for 4.9% of the total effect. The effect value of emotional intelligence and life satisfaction was 0.029, accounting for 5.4% of the total indirect effect.

Emotional intelligence can affect the life satisfaction of master’s students through the mediating or chain mediating effect of stress perception and loneliness, which provides a theoretical basis for improving the quality of life and mental health of master’s students.

To evaluate the causal relationships between lipids (low-density lipoprotein cholesterol, high-density lipoprotein cholesterol [HDL-C], triglyceride [TG], apolipoprotein A-I [ApoA-I], apolipoprotein B) and non-alcoholic fatty liver disease (NAFLD) through a two-sample Mendelian randomization (MR) study.

Summary datasets of genome-wide association studies of lipids and NAFLD in European ancestry were leveraged, and single nucleotide polymorphisms associated with lipids were selected as instrumental variables. Several univariable MR analyses were conducted, including inverse-variance weighting method, MR-Egger regression, weighted median estimation, MR pleiotropy residual sum and outlier method. A multivariable inverse-variance weighting method was further used to evaluate the independent causal effect of lipids on NAFLD.

Univariable inverse-variance weighting MR showed that genetically predicted higher HDL-C (OR=0.774, 95%CI: 0.708-0.845, P<0.001) and ApoA-I (OR=0.878, 95%CI: 0.796-0.968, P=0.009) were associated with a lower risk of NAFLD, while genetically predicted higher TG (OR=1.323, 95%CI: 1.201-1.458, P<0.001) was associated with a higher risk of NAFLD. The causal effects of HDL-C and TG on NAFLD remained consistent in multivariable MR when adjusting for other lipids, body mass index, and type-2 diabetes.

Our study supports a putative causal relationship between HDL-C, TG, and NAFLD.

To analyse the current situation and trends of wasting and overweight obesity among Han Chinese college students from 2000 to 2019, and to provide a basis for the prevention of wasting and overweight obesity among college students.

The body mass index data of 72 983 Han Chinese college students were selected from five national surveys on students’ physical fitness and health from 2000 to 2019, and the “height-standard weight method” used in the 1985 national survey on physical fitness and health was used to screen for emaciation and overweight-obesity, and the detection rate, increase and annual growth rate of emaciation and overweight-obesity were calculated for college students by gender and age. The detection rate, increase rate and annual growth rate of college students were calculated by gender and age. Statistical analyses were performed using one-way ANOVA, sample-weighted linear regression, χ² test and χ² trend test.

From 2000 to 2019, the BMI of Chinese Han college students all showed a continuous increasing trend, with different growth rates for male and female students in each age group (except for the female group, the P-trend value for male students in each age group was <0.05). Both male and female students' wasting detection rates showed a decreasing trend from 2014-2019.From 2000 to 2019, the overweight and obesity rate of Chinese Han college students continued to increase, and the overweight and obesity rate of male students was higher than that of female students.From 2000 to 2019, the wasting of Chinese Han college students aged 19 to 22 years old The annual growth rate of overweight and obesity of male students has been decreasing, and the annual growth rate of overweight and obesity of male students has been increasing, and the difference in the increase of the annual growth rate of overweight and obesity of male students in each age group is relatively small. 2010-2019, the annual growth rate of overweight and obesity of female students began to increase gradually, and the increase was the largest in 2014-2019, and the increase was the most obvious The largest increase in the annual growth rate of overweight obesity among female students was observed in the age group of 22 years.

At 2019, the trend of the growth of college students' wasting rate has been alleviated, but the overweight and obesity rate is in a continuous growth trend, the relevant government departments should formulate targeted physical health policies to prevent and alleviate the problem of college students’ overweight and obesity.

To investigate heterogeneous trajectory of sarcopenia and its associated factors among older adults with multimorbidity.

Based on the Asian Working Group for Sarcopenia 2019 Consensus, three waves of data in 2011, 2013, and 2015 from the China Health and Retirement Longitudinal Study were utilized. Latent growth mixture model and multinomial logistic regression were selected to identify heterogeneous sarcopenia trajectories and associated factors among older adults with multimorbidity.

Of the 1 254 participants, four heterogeneous trajectories of sarcopenia were identified: high initial but sharply declining trajectory (7.5%,n=93), low and stable change trajectory (64.0%, n=803), high and stable change trajectory (23.5%, n=295), low initial but sharply increasingtrajectory (5.0%, n=63). Disability, body mass index (BMI), cognition, sleep duration, smoking habits, and alcohol consumption were associated with different sarcopenia trajectories.

There are heterogenous sarcopenia trajectories among older adults with multimorbidity, targeted intervention regarding disability, BMI, cognition, sleep, smoking, and drinking should conducted to prevent sarcopenia.

To analyze the non-occupational carbon monoxide (CO) poisoning incidents in Jinan City from 2011 to 2022, to grasp their epidemiological characteristics, and propose suggestions for further reducing the morbidity and mortality of non-occupational CO poisoning.

Descriptive epidemiological method was used to analyze the data. The chi-square test was used to compare the rates.

From 2011 to 2022, Jinan City reported 3 003 incidents of non-occupational CO poisoning, with 4 208 cases of poisoning. The average number of poisoning cases per year was 351, with the population over 60 years old being the high-risk group for poisoning. There was a total of 125 deaths, with a fatality rate of 2.97%. The mortality rate of critically ill patients was significantly higher than that of other groups (χ²=45.54, P<0.001). The average annual incidence of non-occupational CO poisoning was 47.48 per million, and the average annual mortality rate was 1.18 per million. The date of occurrence of non-occupational CO poisoning in Jinan City had obvious seasonal characteristics, which was consistent with the winter and spring heating seasons. Among poisoning incidents with clear causes, improper heating was a major cause of poisoning (2 554, 87.4%), followed by gas leaks (207, 7.1%), and the consumption of charcoal hot pots and other charcoal-grilled foods (113, 3.9%).

Although the incidence of non-occupational CO poisoning in Jinan is on a downward trend, the number of people poisoned is still high, and the causes of poisoning are diverse. Therefore it is necessary for multiple departments to jointly carry out the corresponding inspection and preventive work while strengthening the safety education for the residents.

To understand the air pollution level, to analyze the source apportionment of metals and metalloids in PM_2.5 and to evaluate its health risk in the city of Hefei.

The concentration of 10 elements (As,Cd,Cr,Ni,Pb, Mn,Se, Al and Sb)in PM_2.5 samples was collected in Hefei city from January 2018 to December 2022, which was used to analyze the pollution level and source apportionment was determined by inductively coupled plasma mass spectrometer(ICP-MS). Correlation analysis, principal components analysis and cluster analysis were used to analyze the sources of metals and metalloids. A health risk assessment model was used to evaluate the health risk of population of 4 carcinogenic elements(As,Cd,Cr,Ni) and 5 non-carcinogenicelements(Pb,Mn,Se,Al,Sb).

The total average concentration of 10 elements in PM_2.5 was in an order of Al>Pb>Mn>As>Se>Sb>Ni>Cr>Cd>Tl and presented an obvious seasonal variation characteristic, higher in winter and spring, lower in summer and autumn.The mixed sources of coal burning, traffic and industry, dust and industrial emissions sources were the main sources of metals and metalloids in ambient PM_2.5 in Hefei.The respiratory pathway exposures of these elements assessed by annual excess risk were between 1.67×10^-7and 4.22×10^-15, which were below the acceptable risk level of population (10^-6).

The main sources of metals in Hefei are mixed sources, soil dust sources and industrial sources. The respiratory pathway exposures of most of the elements assessed by annual excess risk are below the acceptable risk level of population.

To explore the incident response capability of adverse event following immunization (AEFI) of vaccination staff in Chongqing.

Descriptive epidemiological methods were used to analyze the level and influencing factors of AEFI response capability among committees and vaccination workers in basic-level CDC and Vaccination units in Chongqing.

Among the 994 surveyed individuals, 97.0% had a medical background. The survey respondents answered AEFI disposal related questions with a total score of 35, with an average score of (18.0±5.1) points. Vaccination personnel with work experience of 21-30 years scored lower(β=-1.446, 95%CI: -2.888--0.004), and the ones who participated in district and county-level events(β= 3.223, 95%CI: 1.597-4.849), participated in municipal level events(β=3.885, 95%CI: 1.882-5.887), as well as city and district/county level participants(β=4.998,95%CI: 3.292-6.705) scored higher.

The disposal ability of AEFI among the basic-level vaccinators in Chongqing is uneven, and training should be strengthened in the future.

To understand the impact and effect value of basic medical insurance on the health status of children in China, and to propose corresponding countermeasures and suggestions.

Based on the data from the Chinese Family Panel Studies in 2016 and 2020, this study examined the extent to which basic medical insurance impacts children’s health using the Propensity-Score-Matching and Difference-in-Difference models.

The findings indicated that basic medical insurance could promote the health status of children by 4.9%(β=0.049,SE=0.028). However, the mediating effects of reducing health costs and improving health service utilization were found to be insignificant. Moreover, the study revealed that the health status of preschool children, girls, rural areas, western regions, and low-income families can be improved by 9.1%(β=0.091,SE=0.038), 7.8%(β=0.078,SE=0.043), 9.3%(β=0.093,SE=0.041), 12.0%(β=0.120,SE=0.051), and 9.3%(β=0.093,SE=0.055) respectively.

This study concludes that basic medical insurance plays a positive role in enhancing children’s health. Therefore, it is crucial to continuously strengthen the basic medical insurance system and reinforce the multi-tiered healthcare security framework. Attention should also be given to ensuring fairness for girls and children in rural and western areas, in order to fully protect children’s health.

To investigate the influenza vaccination willingness and influencing factors among elderly patients with chronic diseases in Chongqing, providing a scientific basis for the development of targeted vaccine policies and intervention measures.

A multi-stage sampling method was employed to randomly select 1 280 elderly patients with chronic diseases in five districts of Chongqing for an investigation into their influenza vaccination willingness. Univariate analysis was performed using the t-test and chi-square test, and binary logistic regression analysis and the standardized score were used to analyze the influencing factors of influenza vaccination willingness among elderly patients with chronic diseases.

Of the 1 211 eligible survey respondents, only 13.1% of elderly patients with chronic diseases had received the influenza vaccination during the 2022-2023 influenza season, and 56.3% were willing to receive the influenza vaccination in the 2023-2024 influenza season. The willingness to receive influenza vaccination among elderly patients with chronic diseases was higher among ethnic minorities (OR=3.49, 95%CI:1.21-10.02), households or unemployed individuals (OR=2.53, 95%CI:1.05-6.09), individuals with an average monthly household income per capita exceeding 5 000 RMB (OR=2.86, 95%CI:1.33-6.13), those with qualified knowledge of influenza vaccination (OR=1.38, 95%CI:1.02-1.87), and under the policy of free vaccination (OR=56.97, 95% CI:24.38-133.09). The behavioral and social drivers (BeSD) survey indicated that the belief in the effectiveness and safety of the influenza vaccine and fear of infecting friends or family members were the primary driving factors of influenza vaccine uptake, while the perception of the high costs of influenza vaccination was the most significant barrier.

The influenza vaccination willingness among elderly patients with chronic diseases in Chongqing needs further improvement. Governmental authorities, healthcare institutions, and communities should enhance the dissemination of knowledge about influenza vaccines, enhance social support, implement subsidies or free vaccination policies for priority populations, and encourage proactive influenza vaccine uptake among elderly patients with chronic diseases.
