To examine the correlation between body composition and insulin resistance (IR) within the general population of different genders.

The data for this study were sourced from the Hefei area data of the Chinese Residents Cardiovascular Disease and Risk Factors Monitoring Project conducted in 2021, with a total of 1 144 subjects being included,including 568 males and 576 females. The ratio of triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) was used as an alternative indicator of insulin resistance. A chi-square test was employed to analyze the association between body composition metrics—such as body mass index (BMI), percent body fat (PBF), percent body muscle (PBM), visceral fat area (VFG), and waist circumference (WC)—and the TG/HDL-C ratio. Logistic regression analysis was used to identify the factors influencing body composition in individuals with a TG/HDL-C ratio exceeding the tangent point value. The dose-response relationship between body components and the TG/HDL-C ratio was explored using restricted cubic splines, a statistical method that allows for the examination of nonlinear relationships.

The positive detection rate of IR (the rate of TG/HDL-C above the cut point value) was 15.85% in men and 4.69% in women.After adjusting for confounding factors, logistic regression analysis showed that compared with the control group, the risk of IR in the male population was 5.58 times in the obese group (OR=5.58, 95%CI:1.98-15.72), PBF was 7.90 times in the third quartile (OR=7.90, 95%CI:1.68-37.15), the fourth quartile of PBF was 8.20 times (OR=8.20, 95%CI:1.75-38.40), and the third quartile of PBM was 0.27 times (OR=0.27, 95%CI:0.10-0.71), the PBM was 0.09 times in the fourth quartile group (OR=0.09, 95%CI:0.02-0.44), 3.11 times in the group with high VFG (OR=3.11, 95%CI:1.45-6.68), and 4.28 times in the group with higher VFG (OR=4.28, 95%CI:1.45-12.64). Abdominal obesity was 2.21 times (OR=2.21, 95%CI:1.08-4.56). In the female population, the risk of IR was 6.61 times in the obese group (OR=6.61, 95%CI:1.08-65.66) and 8.52 times in the higher VFG group (OR=8.52, 95%CI: 1.90-70.86) (P<0.05). The limited cubic spline showed that BMI, PBF, PBM, VFG, WC had dose-response relationship and approximate linear relationship with TG/HDL-C.

The body composition of community residents is closely associated with the risk of insulin resistance. Individuals who are obese or have high levels of visceral fat are at greater risk for insulin resistance. To mitigate this risk, it is imperative to reinforce lifestyle interventions that prioritize maintaining a higher percentage of muscle mass.

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.

The aim of this study is to test the reliability and validity of the Chinese version of CP-Q among college students.

The English version of the CP-Q was translated, back-translated following the Brislin model, and cultural adaptation was performed to develop the Chinese-version CP-Q.The reliability, validity and feasibility of the questionnaire were evaluated by investigation of questionnaires offline and electronic questionnaires online.

A total of 658 participants were investigated with 593 valid questionnaires obtained, the total effective rate was 90.1%.Subjects finished the Chinese-version CP-Q and Pittsburgh Sleep Quality Index (PSQI); Munich Chronotype Questionnaire (MCTQ) and 24h dietary recalls. Moderate to strong correlations were observed in the sleep/wake schedules between the Chinese-version CP-Q, PSQI and MCTQ, both for work/study days and free days, the highest was the free day sleep time r=0.922(P<0.001).The correlations between sleep, wake, first eating event, lunch time and last eating event in work/study days and free days with the same variables in the 24h recall showed r=0.441-0.659 (P<0.05), in addition to the lunchtime in free days (r=287, P=0.076). A total of 7 items among the 17 variables in the Chinese-version CP-Q evaluated in the test and retest phases presented intraclass correlation coefficients ≥0.75.

The Chinese-version CP-Q has good reliability and validity and could reflect the real situation of eating time and sleeping time. The questionnaire can be used to assess the status of one’s chrononutrition.

To analyze the characteristics of suspected adverse events following immunization (AEFI) in Guiyang City from 2014 to 2023, to evaluate the safety of immunization in Guiyang City, and to provide guidance for improving AEFI monitoring.

Collect AEFI data and vaccine immunization data in Guiyang City from 2014 to 2023 through the “National Immunization Planning Information System” and “Guizhou Province Immunization Planning Information Management System.” Use descriptive epidemiological methods to statistically analyze the epidemiological characteristics and reported incidence rates of AEFI in Guiyang City.

From 2014 to 2023, Guiyang City reported a total of 4 498 cases of AEFI, with an average annual reported incidence rate of 14.63 per 100 000. The incidence rate was the highest in 2023 (1 358 cases, 42.43/100 000) and the lowest in 2015 (23 cases, 1.85/100 000). The reported incidence rate had a statistically significant difference among different years (χ²=3 638.04,P<0.001). Yunyan District reported the most cases (1 539 cases, 25.86/100 000), while Xifeng County reported the least cases (86 cases, 6.67/100 000), and the difference among different regions was statistically significant (χ²=890.10,P<0.001). The most cases were reported in November (588 cases, 24.7/100 000) and the least in February (136 cases, 8.37/100 000), and there was a statistically significant difference among different months (χ²=277.31,P<0.001). The male-to-female ratio was 1.10：1.00, with the highest reports in the age group ≤1 year (2 697 cases, 59.96%). The outcome was recovery or improvement in 96.47% of cases.

2014-2023 AEFI in Guiyang is mainly a general response and the vaccination safety is good. However, the work carried out in different places varies and the monitoring sensitivity needs to be further enhanced.

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 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 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.
