To understand the longitudinal association of adverse childhood experiences and self-control with mobile phone dependence among junior high school students, and to provide reference for the development of prevention and control measures.

Convenience sampling was used to select 863 junior high school students from 18 classes in 2 middle schools as the research subjects. The Childhood Adversity Questionnaire, Self-Control Scale, and Mobile Phone Dependence Index Scale were used as the survey tools. Two follow-up surveys were conducted in November 2023 (T1) and May 2024 (T2). SPSS 23.0 was used for independent sample t-tests, one-way ANOVA, paired sample t-tests, partial correlation analysis, and factor analysis. Mplus 8.3 software was used for cross-lagged analysis and mediation effect testing.

The partial correlation analysis revealed that both the adverse childhood experiences and self-control were statistically significantly correlated with the mobile phone dependence of junior high school students (r=-0.646-0.762, P<0.05). The cross-lagged model analysis indicated that the adverse childhood experiences at T1 could positively predict the mobile phone dependence at T2 (β=0.107, 95% CI: 0.050-0.164, P<0.05); the mediation model analysis showed that the mediating effect of the adverse childhood experiences on the influence of self-control on the mobile phone dependence of junior high school students was (β=0.019, 95% CI: 0.006-0.033, P<0.05).

Adverse childhood experiences could positively and indirectly affect mobile phone dependence through self-control among junior middle school students.

To explore the association between self-reported myopia prevalence and parental reproductive age in middle school students.

A questionnaire survey was conducted among 1 485 students from 11 junior/senior high schools in Tong’an District, Xiamen through multistage cluster sampling, which was used to collect information on the characteristics of the students and their parents, as well as self-reported vision. Logistic regression models were used to analyze the relationship between parental reproductive age, parental vision and self-reported myopia prevalence in middle school students.

The self-reported myopia prevalence of middle school students was 80.4%. Among the students whose parental reproductive age was ≥40 years, the self-reported myopia prevalence was higher, which accounted for 84.2% and 83.2%, respectively (P<0.05). After adjusting for covariates, compared with students whose parental reproductive age was <20 years, the middle school students in groups of fathers aged 30-39 years (OR=2.04, 95% CI: 1.02-4.10) and ≥40 years (OR=2.18, 95% CI: 1.04-4.60), and mothers aged 30-39 years (OR=3.41, 95% CI: 1.83-6.36) and ≥40 years (OR=3.44, 95% CI: 1.66-7.12) had a higher risk of self-reported myopia. Among the students whose maternal reproductive age was 30-39 years, the risk of self-reported myopia increased with an increase in paternal reproductive age (P<0.05). When neither parent was myopic, the risk of self-reported myopia among students increased in the groups of fathers aged 30-39 years (OR=3.34, 95% CI: 1.35-8.49), ≥40 years (OR=3.93, 95% CI: 1.48-10.44), and mothers aged 20-29 years (OR=2.70, 95% CI: 1.33-5.49), 30-39 years (OR=3.04, 95% CI: 1.43-6.47), and ≥40 years (OR=3.93,95% CI: 1.63-9.49). When either parent was myopic, the differences in self-reported myopia risk were not statistically significant across different parental reproductive ages.

Advanced parental reproductive age is associated with an increased risk of self-reported myopia among middle school students, particularly in those with both parents being non-myopic. It is necessary to pay more attention to the prevention and control of myopia of middle school students with older parental reproductive age.

To examine the impact of social participation on life satisfaction in perimenopausal women and the mediating role of depression over time.

Using China Health and Retirement Longitudinal Study (2011—2018) data, a latent growth model analyzed trajectories of social participation, depression, and life satisfaction in 1 133 perimenopausal women and tested the longitudinal mediation of depressionin in the relationship between social participation and life satisfaction.

Social participation, depression, and life satisfaction showed increasing trends. After controlling for education, the intercept of social participation negatively predicted the intercept of depression (β=-1.198, P<0.001), and the intercept of depression negatively predicted the intercept of life satisfaction (β=-0.058, P<0.001). The slope of social participation negatively predicted the slope of depression (β=-0.909, P<0.05), while the slope of depression negatively predicted the slope of life satisfaction (β=-0.101, P<0.001). The intercept and slope of depression showed longitudinal mediation between social participation and life satisfaction, with indirect effects of 0.069(95% CI: 0.037-0.112) and 0.092(95% CI: 0.024-0.215),respectively.

Social participation indirectly affects life satisfaction by influencing the level of depression. Providing flexible participation opportunities and emotional support may enhance psychological well-being and life satisfaction in perimenopausal women.

To analyze the prevalence of diabetes and self-management behaviors among elderly Dai, Hani, and Bai in rural areas of Yunnan.

A multi-stage stratified random sampling approach was used to conduct a questionnaire survey and blood glucose measurement on 4 229 rural residents aged ≥60 years from the Dai, Hani, and Bai ethnic groups in Yunnan.

The age-standardized prevalence rate of diabetes among elderly individuals in the surveyed areas was 7.6%for the Dai ethnic group, 5.0% for the Hani ethnic group, and 16.0% for the Bai ethnic group. The differences in diabetes prevalence among the three ethnic groups were statistically significant (χ²=105.856, P<0.001), with the Bai group having the highest prevalence, followed by the Dai and then the Hani. The differences in prevalence among the three ethnic groups within each age group were all statistically significant (all P<0.01). Among diabetic patients, the rates of adhering to taking prescribed medications, self-monitoring blood glucose, and taking at least one measure to control blood glucose in the past two weeks were 94.7%, 42.1%, and 100.0% for the Dai ethnic group, 79.4%, 26.5%, and 94.1% for the Hani ethnic group, and 98.2%, 57.6%,and 98.8% for the Bai ethnic group, respectively. Across all three ethnic groups, dietary control was the most commonly adopted measure for managing blood glucose in the two weeks prior to the survey. The overall blood glucose control rate among the three ethnic groups was 47.7%. The blood glucose control rates among elderly diabetic patients were 50.9% for the Dai, 58.8% for the Hani, and 44.2% for the Bai ethnic groups, with no statistically significant differences observed among the groups (P>0.05).

Significant ethnic differences in diabetes prevalence and self-management behaviors are observed among elderly individuals from the Dai, Hani, and Bai ethnic groups in rural Yunnan. Targeted health interventions and management strategies should be developed to address ethnic backgrounds and health needs of these populations.

To explore the relationship between subjective cognitive decline and frailty in community-dwelling older adults with comorbidities, and analyze the mediating effects of self-perceptions of aging and cognitive reserve.

From June to October 2023, 505 community-dwelling older adults aged 65 and above in Xinxiang City with comorbidities were selected to conduct a questionnaire survey. Descriptive statistics, ANOVA and correlation analysis were performed on the data, and AMOS 27.0 was used to construct a chain mediation model.

Subjective cognitive decline had a positive impact on frailty (β=0.100, 95% CI: 0.006-0.191, P=0.040). Self-perceptions of aging and cognitive reserve played a mediating role between subjective cognitive decline and frailty (β=0.079, 95% CI: 0.042-0.123, P<0.001; β=0.029, 95% CI: 0.011-0.056, P<0.001), accounting for 36.12% and 13.37% of the total effect value, respectively. Moreover, self-perceptions of aging and cognitive reserve jointly played a chain-mediating role between subjective cognitive decline and frailty (β=0.010, 95% CI: 0.004-0.021, P<0.001), accounting for 4.77% of the total effect value.

The findings that self-perceptions of aging and cognitive reserve play independent mediating roles and a chain-mediating role between subjective cognitive decline and frailty suggest that attention should be paid to the subjective feelings of community-dwelling older adults with comorbidities. It is essential to cultivate a positive view of aging among the elderly and enhance their cognitive reserve levels. By doing so, the onset of frailty can be delayed, thus promoting healthy aging.

To explore the compliance of telemedicine services on third-party platforms since the release of the“Telemedicine Supervision Rules (Trial)” in 2022.

An anonymous standardized patient method was employed to assess the compliance of diagnostic behaviors on eight well-known, large-scale third-party internet healthcare platforms in China.Diagnostic scenarios were designed around five representative clinical cases. Based on the Telemedicine Supervision Rules (Trial),20 regulatory indicators were extracted across five key dimensions—clinical practice supervision, pharmaceutical services, prescription and medical record standards, identity verification, and quality and safety oversight.

The platforms generally deviated from policy requirements in areas such as online first diagnosis, medication prescribed before diagnosis and prescription authenticity, with average compliance rates of 29%, 25%, and 10%, respectively. Some platforms were suspected of using artificial intelligence to replace doctors in consultations. Compliance was better in areas such as physician qualification certification and real-name authentication, patient real-name authentication, termination of online medical services, and prohibiting patients from being directed to other medical providers, with only a few cases of violations. The causes of compliance issues included the policy’s failure to adapt to industry development, low government regulatory willingness, weak regulatory effectiveness, and the profit-driven behavior of platforms and healthcare providers.

Third-party platforms still face varying degrees of compliance issues in medical practices, pharmaceutical services, prescription regulation, and personnel identity management. It is recommended to strengthen government regulatory functions, enforce platform accountability, improve the dynamic adjustment mechanism of policies, and enhance social supervision and industry self-regulation.

To analyze the disease burden of patients with cervical cancer (CC) and precancerous lesions in Suzhou in 2022,evaluate the cost-effectiveness of different human papillomavirus (HPV) vaccines, and explore the optimal vaccination mode in Suzhou.

A retrospective survey was conducted to investigate the medical expenses and hospitalization costs of patients with CC and precancerous lesion in Suzhou City in 2022. Using the PRME model, we evaluated the cost-effectiveness of different immunization strategies and combined sensitivity analysis to determine the optimal solution.

Assuming that 13-year-old girls in Suzhou received domestic bivalent HPV vaccine (2vHPV) or 9-valent HPV vaccine (9vHPV) in 2022, and the vaccination rate reached 90.00%, the model predicted that it could avoid 77-103 cases of CC and 17-23 deaths in the future, saving 42.54-56.64 disability-adjusted life years (DALYs). Compared with not receiving the vaccine, the incremental cost-effectiveness ratio (ICER) of 2vHPV and 9vHPV was 10 423.54 yuan/DALYs and 131 348.23 yuan/DALYs, respectively, and both were cost-effective.

Both 2vHPV and 9vHPV are cost-effective. Compared to 9vHPV, vaccinating 13-year-old girls with 2vHPV is a more cost-effective vaccination strategy. The cost of vaccines plays a crucial role in determining the ICER. When the price of 9vHPV drops below 90.50 yuan per dose, its ICER becomes lower than that of 2vHPV at 63.00 yuan per dose. Therefore, reducing HPV vaccine prices through government negotiation, centralized procurement, and promoting domestic vaccines is recommended.

In order to further optimize the allocation of primary health resources, this study analyzed the status quo and equity of primary health resources allocation in Inner Mongolia from 2019 to 2023.

Using Lorenz curve, Gini coefficient and Theil index, the equity of primary health resource allocation in Inner Mongolia was measured and analyzed.

In the medical and health resources of all the cities in Inner Mongolia Autonomous Region, Hohhot ranked first. According to the fairness of population allocation, the Gini coefficient ranged from 0.025 9 to 0.155 3，the total Theil index ranged from 0.004 0 to 0.077 3，and the intra-regional variance rates ranged from 61.65% to 93.50%. According to the fairness of geographical area allocation, the Gini coefficient ranged from 0.453 8 to 0.516 5, the total Theil index ranged from 0.256 7 to 0.352 8, and the inter-regional difference rate ranged from 13.12% to 24.93%. According to the fairness of GDP allocation, the Gini coefficient ranged from 0.100 7 to 0.379 2, the total Theil index ranged from 0.096 9 to 0.240 2, and the inter-regional difference rate ranged from 24.56% to 38.06%.

The total amount of primary health resources in Inner Mongolia has achieved continuous growth, but there is a structural imbalance in the allocation of medical human capital. The fairness of allocation according to population and GDP is significantly better than that according to geographical area. The distribution of primary health resources in different cities is uneven, forming a gradient pattern of "central uplift-edge collapse", with noticeable underutilization of primary health resources.

To explore the factors affecting the acceptance of pre-pregnancy eugenic health examination for women of childbearing age and provide evidence for improving pre-pregnancy health care services.

A multi-stage stratified random sampling method was adopted to investigate the pre-pregnancy eugenic health examination of 1 995 women of childbearing age in Mianyang City, Sichuan Province through questionnaires. Based on the Andersen theoretical model, four logistic regression analysis models were established to explore the factors influencing the acceptance of pre-pregnancy eugenic health examination by women of childbearing age.

The rate of pre-pregnancy eugenic health examination was 61.1%, of which 53.1% were free and 46.9% were self-paid. The predisposing characteristics, enabling resource-financing, enabling resource-organization and perceived needs were incorporated into the regression model layer by layer. It was found that enabling resource-organization had the greatest impact. Model 4 had the strongest overall explanatory power. Logistic regression analysis results showed that women of childbearing age without insurance or only with commercial insurance (OR=0.526, 95% CI: 0.278-0.996) and those who purchased the urban-rural resident basic medical insurance (OR=0.757, 95% CI:0.597-0.959) had a lower rate of pre-pregnancy eugenic health examination compared to those who purchased urban employee basic medical insurance (P<0.05). From the organizational perspective, women of childbearing age who knew about the free pre-pregnancy eugenic health examination policy (OR=2.907, 95% CI: 2.267-3.728). From the perceived demand perspective, women who planned to get pregnant (OR=1.811,95% CI: 1.459-2.249) were more inclined to accept the pre-pregnancy eugenic health examination (P<0.05).

It is necessary to further promote the implementation of free pre-pregnancy health care service policy, strengthen health education based on primary medical and health institutions, and promote more women of childbearing age to take the initiative to accept pre-pregnancy eugenic health examination services.

To investigate the impact of social jetlag on body mass index (BMI) among shift nurses and its underlying mechanisms.

A convenience sample of 429 shift nurses from five tertiary hospitals in Sichuan Province was selected.Data were collected using the Munich Chronotype Questionnaire for Shift Workers (MCTQshift), the Pittsburgh Sleep Quality Index (PSQI), the Morningness-Eveningness Questionnaire (MEQ-5), and BMI measurements. Statistical analyses included univariate analysis, partial correlation analysis, and moderated mediation model testing.

Social jetlag significantly predicted BMI levels (β=0.348, 95% CI: 0.259-0.437, P<0.001). Sleep quality partially mediated the relationship between social jetlag and BMI,with an effect size of 0.101(95% CI: 0.030-0.172, P<0.001), accounting for 29% of the total effect. The predictive effect of social jetlag on BMI (β=0.194, 95% CI: 0.108-0.281, P<0.001) and the effect of sleep quality on BMI (β=-0.121, 95% CI: -0.215~-0.027,P=0.012) were both moderated by chronotype.

This study revealed the potential mechanisms through which social jetlag affects BMI levels among shift nurses. It highlights the importance of reducing social jetlag and improving sleep quality, as well as the role of chronotype in moderating the adverse effects of social jetlag on BMI abnormalities. These findings provide a theoretical basis for nursing managers to develop more scientific and effective interventions for BMI management among shift nurses, ultimately reducing BMI abnormalities and promoting their physical and mental health.
