To analyze the pneumoconiosis mortality change trend, influencing factors and differences between Chinese residents from 2002 to 2021.

Using the Joinpoint model of crude pneumoconiosis mortalityrate and standardized mortalityrate, the annual percentage change (APC) and mean annual percentage change (AAPC) were calculated. The effect of three effects on pneumoconiosis mortality changes was analyzed by the age-period-cohort model.

The urban standardized mortality rate showed an overall downward trend (APC=-0.2%, P>0.05) and increased in rural areas from 2004 to 2021 (APC=7.9%, P<0.001). The age effect showed that both urban and rural pneumoconiosis mortality rate increased with increasing age. The period effect increased with time, and it was different between urban and rural areas, with the risk of urban death decreasing, and the risk of rural death increasing. The cohort effect showed that the risk of death decreased with later birth, and the rural resident birth cohort showed a fluctuating trend.

The increasing effect of age, period and cohort will affect rural pneumoconiosis mortality more than in urban areas.

To explore the epidemiological characteristics of foodborne disease events in a rural banquet in Sichuan Province from 2004 to 2023, and to provide a scientific basis for the prevention and control of foodborne disease in the rural banquet.

The data of foodborne disease events in a rural banquet in Sichuan Province from 2004 to 2023 were collected from the National Foodborne Disease Outbreaks Surveillance System and National Management Information System of Public Health Emergencies and analyzed by descriptive statistics.

From 2004 to 2023, a total of 189 foodborne disease events in rural banquet were reported in Sichuan Province with 5 971 cases and 22 deaths, and the case fatality rate was 0.37%. The third quarterly was the high incidence period, accounting for 43.39% of the total events. The top three regions with the highest number of reported events were Chengdu (25 events), Luzhou (19 events) and Yibin (18 events). Microbial pathogens were the main pathogenic factors, accounting for 66.67% of the total events. Chemicals were the main causes of death, with 15 and 5 deaths caused by methanol and nitrite, respectively. Meat and meat products were the main causes of foodborne diseases. Improper processing and storage were the main inducing factors.

The targeted health education, supervision, monitoring, and emergency handling should be carried out to effectively prevent and control foodborne disease events in rural banquets.

To explore the level and influencing factors of dietary recommendation knowledge among residents aged 18-64 years in Hunan Province in 2021, and to provide a reference for targeted dietary nutrition education.

In 2021, a total of 4351 adult residents from 13 districts (counties) survey sites of Hunan Province were surveyed using the Nutrition and Health Knowledge Questionnaire. The total score of the questionnaire was 100. The knowledge dimension of dietary recommendation included 19 knowledge points, with a total score of 30, the total score of this dimension ≥ 22.5 was considered to be aware of dietary recommendation related knowledge. Binary logistic regression was used to analyze the influencing factors of adult residents’ knowledge level of dietary recommendation.

A total of 4 010 adults were included in the survey, with an average age of (38.6±12.0) years. The average score of dietary recommendation knowledge dimension was (17.7±4.4) points, and the awareness rate of knowledge about dietary recommendations was 13.6%. The results showed that there were significant differences in the scores and awareness rates of dietary recommendation related knowledge among residents with different genders, age groups, education levels, work units and specific situation of chronic diseases (P<0.05). Logistic regression analysis showed that compared with the corresponding reference group, the awareness rate of dietary recommendation related knowledge was relatively higher in female residents (OR=1.267, 95%CI=1.051 - 1.526) and residents with education level of junior high school and above [junior high school (OR=1.528, 95%CI=1.042-2.242), seniorhigh school (OR=2.123, 95%CI=1.421 - 3.172), college/professional college (OR=3.653, 95%CI=2.386-5.593),bachelor’s degree and above (OR=3.385, 95%CI=2.120 - 5.405)]. Compared with those working in medical and health institutions, those working in education-related institutions had a lower awareness rate of dietary recommendation knowledge (OR=0.547, 95%CI: 0.322-0.930). Compared with those without chronic diseases, the awareness rate of dietary recommendation was lower in adults who did not know their specific situation of chronicdiseases (OR=0.613, 95%CI=0.487-0.772).

There is significant room for improvement in the knowledge level of diet recommendation among adult residents in Hunan Province. In the future, more attention should be paid to the dietary nutrition education of adult males, middle-aged and elderly people, patients with chronic diseases, and residents who do not work in medical and health institutions.

To analyze the association between family functioning and primary school students’ emotion regulation strategies, and to provide a theoretical basis for promoting the development of primary school students’ psychological health.

A random cluster sampling method was used to select 9 868 students from six primary schools in a region of Xinjiang for the study, and questionnaires were administered using the Basic Information Questionnaire, the Family Functioning Scale (FAD), and the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA).

The total family functioning score of primary school students was (138.99±17.54), and multiple linear regression analyses showed that total family functioning (β=-1.03), problem-solving (β=-0.10), affective involvement (β=-0.09), communication (β=0.05), affective response (β=0.05), and age (β=0.50) had a predictive role in primary school students’ cognitive reassessment strategy effect (R²=0.101, all P<0.01). Total family functioning (β=0.22), problem-solving scores (β=0.18), emotional involvement scores (β=0.09), roles (β=0.04), and communication (β=-0.03) were predictive of primary schools’ children’s expressive inhibition strategies (R²=0.120, all P<0.05).

Elementary school students’ family functioning is at a moderately low level, and upper primary schools’ students are more inclined to use the emotion regulation strategy of expression inhibition, which can be improved by increasing the level of family functioning in each dimension.

To explore the relationship between online sexual harassment experiences and the sexual values of primary and secondary school students, and to provide scientific reference for comprehensive sex education for primary and secondary school students.

The study used a multi-stage stratified cluster sampling method to select 4 051 primary and secondary school students from 9 schools in Fushun County, collecting information on the social demographics, online sexual harassment experiences, sexual values, psychological resilience, and social capital of primary and secondary school students. The study analyzed the impact of online sexual harassment experiences on the sexual values of primary and secondary school students using a multiple linear regression model. The mediating effect of psychological resilience was tested using the Bootstrap method (repeated sampling 5 000 times).

It showed that out of 4 051 primary and secondary school students surveyed, 754 students (18.61%) reported experiencing online sexual harassment. In the regression model, online sexual harassment experiences were negatively associated with scores on sexual violence and safety perceptions (β=-0.50, P<0.05), gender power and social gender perceptions (β=-0.25, P<0.05), and positively associated with scores on sexual and reproductive health perceptions (β=0.31, P<0.05). Psychological resilience played a partial mediating role (β=-0.38, P<0.05), accounting for 46.34% of the mediating effect between online sexual harassment experiences and the sexual values of primary and secondary school students.

Online sexual harassment experiences are negatively associated with the sexual violence and safety perceptions, gender power and social gender perceptions of primary and secondary school students while being positively associated with the sexual and reproductive health perceptions of primary and secondary school students. Improving psychological resilience may help promote the formation of scientific and normative sexual values among primary and secondary school students.

To analyze the influencing factors of bullying and suicide-related behaviors among primary and secondary middle school students in Hubei Province, and to summarize the high-risk groups of bullying and suicide-related behaviors (thoughts/plans/attempts).

A stratified random sampling method was used to select primary, middle, and high school/vocational high school students from 4 counties in Hubei Province for questionnaire survey. Multivariate logistic regression model was used to analyze the influencing factors of bullying and suicide-related behaviors. The interaction between bullying and related variables was by adding interaction terms.

A total of 1618 students were included in the survey. In the past 12 months, 33.9% of them had been bullied, 17.9%, 12.2%, and 7.8% of them had suicidal ideas, plans, and behavior. The RR values of suicide thoughts, plans, and attempts among bullies were 3.03(95%CI：2.24-4.12), 2.21(95%CI：1.57-3.12), and 2.28(95%CI：1.51-3.45). Middle school students, those with poor relationships with their parents, those who are not confident in their appearance, and those whose friends do not care about them are more likely to be bullied. Students who have been bullied, female students, ethnic minorities, and students who have heard of their classmates’ suicide-related behaviors are more likely to engage in suicide-related behaviors.

The main influencing factors of bullying and suicide-related behaviors among primary and middle school students in Hubei Province were summarized, which could provide a reference for future health interventions.

To understand the obesity, overweight and malnutrition status of primary and secondary school students in Karamay from 2014 to 2021, and to provide basis for targeted interventions on nutritional status of primary and secondary school students.

70 792 autumn physical health monitoring data of primary and secondary school students in Karamay from 2014 to 2021 were collected, and SPSS 22.0 software was used. Chi square tests were used for gender comparisons, and trend chi square tests were used for statistical analysis of age groups and years.

The malnutrition rate of primary and secondary school students in Karamay City decreased from 11.4% in 2014 to 5.7% in 2021 (χ²=1 329.791, P<0.01), and the overweight and obesity rates increased from 14.1% and 8.4% to 17.2% and 14.0% respectively (χ²=687.21 and 725.13, respectively, with P<0.01). From 2014 to 2021, the detection rates of malnutrition (except 2018), overweight and obesity (except 2014) in boys were higher than those in girls (P<0.01).

The malnutrition status of primary and secondary school students in Karamay City has been improved yearly, but the overweight and obesity rates have shown an increasing trend year by year. The bipolar problem of male students’ nutritional status is more prominent than that of female students. Schools and health management departments should carry out targeted interventions and countermeasures.

To investigate the demand for home medical service among cancer patients in Pudong New Area and analyze the main influencing factors.

A convenience sampling method was used, and a self-designed questionnaire was administered to 1 161 cancer patients in Pudong New Area. Single-factor analysis, non-parametric rank sum test, and multiple linear regression model were used to analyze the influencing factors.

18.2% of cancer patients had home medical service demands, with demands across all four dimensions. Among which the demand for health education, social support and rehabilitation guidance was more. Cancer patients’ needs are influenced by factors such as age, education level, economic status, and more (P<0.05). The driving factors include the number of comorbidities (β=0.111, t=3.643, P<0.001), being bedridden (β=0.121, t=4.299, P<0.001), and having a college degree or higher (β=0.071, t=2.416, P=0.016). The inhibiting factors include economic status (β=-0.072, t=-2.057, P=0.04) and daily condition (β=-0.192, t=-5.219, P<0.001).

Home medical services have significant demands among cancer patients. Relevant institutions should combine the characteristics of patient needs, improve service project evaluation, cost payment models, and relevant laws and policies, and strengthen supervision to promote the standardized and sustainable development of home medical services.

To explore the association between social isolation, loneliness, and smoking behavior among Chinese older adults.

In this study, data from the 2020 China Health and Retirement Longitudinal Study (CHARLS) were selected and statistically analyzed using Stata 17.0. Binary logistic regression was used to analyze the associations between social isolation, loneliness, and smoking behavior. Multiple interpolation with chained equations was used to fill in missing values and perform sensitivity analyses.

A total of 9 234 older adults aged 60 years and above were included, and the prevalence of social isolation and loneliness was 30.88% and 31.48%, respectively. Multi-model adjustment showed that socially isolated (OR=1.39, 95%CI: 1.23-1.57) older adults were at greater risk of smoking. Subgroup analyses of age and gender showed a greater risk in 65-<75 years (OR=1.25, 95%CI: 1.04-1.50), and men (OR=1.24, 95%CI: 1.07-1.44). No association between loneliness (OR=1.09, 95%CI: 0.95-1.25) and smoking behavior was observed, and the results of sensitivity analyses remained consistent.

In China, the older adults who are socially isolated are more likely to smoke. Therefore a tripartite effort by society, community and family is needed to pay attention to the social contact as well as social participation of older adults, particularly the high-risk groups of social isolation and smoking behaviors, in order to improve the healthy behavior among the older.

To systematically analyze randomized controlled trials (RCT) on improving the coordination of care in emergency medical services (EMS), and to mainly focus on sequential intervention that aimed to achieve seamless care between difference service settings, as well as to provide evidence-based suggestion for improving the integration of emergency medical system.

Using keyword and Mesh-term search, Embase, PubMed, CNKI, Wanfang Database and other eight databases were searched to identify related studies, and then the interventions were confirmed by study screening and quality evaluation. Effectiveness of the interventions were assessed according to treatment time, patient outcomes and satisfaction.

In total, 19 articles were included. Sequential intervention maximumly could shorten pre-hospital time and in-hospital time by 68.7 minutes and 79.8 minutes, respectively. The incidence of adverse events could be reduced by from 3.8% to 16.7%. There were significant reductions in the rates of readmission (20%), mortality (17%) and complication (28.9%). The functional status and satisfaction of the patients in the intervention group were better than that in the control group.

Interventions aiming to improve coordination of care in EMS play a positive role in shortening treatment time and improving patient outcome. Given the quality of the included studies, study locations and study sample, future studies should pay more attention to the rigorousness of their study design and the completeness of their outcome report.
