To describe and analyze the willingness of married women of childbearing age in Guangxi to have children again and the factors affecting them, to understand the reproductive supporting policies expected by women of childbearing age, and to provide a reference basis for the government to optimize the reproductive policy and improve the supporting measures.

Based on the data from the Seventh National Health Service Survey of Guangxi in 2023, women aged 20-49 years old who were married with one or two children were taken as the study subjects, and their willingness to have another child and their influencing factors were analyzed by multifactorial logistic regression.

Of the 934 married women of childbearing age who had children, 12.10% had the desire to have another child. The results of multifactorial logistic regression analysis showed that the married fertile women aged 30-34 years(OR=0.241, 95%CI: 0.111-0.520), 35-39 years(OR=0.162, 95%CI: 0.075-0.350), 40-44 years(OR=0.066, 95%CI: 0.029-0.151), 45-49 years(OR=0.027, 95%CI: 0.011-0.070) and married women of childbearing age who already had two children(OR=0.094, 95%CI: 0.057-0.156) had a lower intention to have another child. The top reason for no longer wanting to have children was financial burden (73.91%). In the survey on complementary policies to address the desire to have more children, the accessibility of education resources and a lighter education burden (29.55%) ranked first.

In Guangxi, the overall willingness of married women of childbearing age to have children again is low, and economic factors are the most important reason affecting childbearing, so government departments need to improve the relevant policies on childbearing, education, housing subsidies and so on.

To study the core competence of the doctor of public health in China and provide theoretical references for standardizing the training system and optimizing the training path of the doctor of public health.

Literature research was used to analyze the connotation, characteristics and promotion path of the core competence of the doctor of public health in China.

The core competence of the doctor of public health in China includes four dimensions: attitude, knowledge, skill and accomplishment. The core competence of the doctor of public health has 8 characteristics: systematism, integration, value, pluralism, dynamics, heterogeneity, research and application. The measures to improve the core competence of the doctor of public health are formed from three levels: the national macro system, the middle mode of colleges or universities, and the individual micro path of students.

The measures to train highly qualified doctor of public health and improve the core competence of the doctor of public health should be implemented. It provides reference for the selection, training and assessment of the public health doctor in a scientific way.

To assess the relationship between the Life’s Crucial 9 (LC9) and stress urinary incontinence (SUI).

Data based on 4 550 participants from the National Health and Nutrition Examination Survey (NHANES) database from 2007 to 2018 were analyzed. Subjects were categorized into T1, T2, and T3 groups based on LC9 tertiles. Logistic regression analysis was used to explore the relationship between LC9 and SUI with parallel trend analysis. Stratified Logistic regression was used to analyze the correlation between LC9 and SUI in different groups. Restricted cubic spline was used to explore the quantitative relationship between LC9 and SUI.

All three models showed a negative correlation between LC9 and SUI incidence (all P<0.001). After adjusting for various covariates, each 10-point increase in LC9 was associated with a 16% reduction in SUI incidence (OR=0.84, 95% CI: 0.79-0.88). T3 was associated with a 40% reduction in SUI incidence compared with T1 (OR=0.60, 95% CI: 0.50-0.72). The results of restricted cubic spline curve (RCS) analysis further showed a significant linear negative association between LC9 and SUI incidence after adjustment for relevant variables (overall P<0.001; nonlinear P=0.261). There was a significant interaction between LC9 score and history of vaginal delivery (P<0.05). Higher LC9 scores in patients with SUI (n=2 047) were significantly associated with mortality from cardiovascular events in SUI (HR=0.10, 95% CI: 0.01-0.79).

LC9 is negatively associated with morbidity and mortality from SUI, and good quality of life management may be a potential strategy to reduce SUI incidence and mortality.

To explore the impact of dynamic changes in depressive states on activity of daily living (ADL) limitations among middle-aged and older adults.

Based on data from the China Health and Retirement Longitudinal Study from 2011 to 2020, 8 617 individuals aged 45 and above were included. The transition characteristics of depressive states were analyzed using a Markov chain model. Latent class analysis was used to identify patterns of depressive changes, and the impact of different depressive trajectories on ADL limitations was assessed using multivariate logistic regression.

The transition probabilities of depressive states showed that the stability of no depression (0.76) and severe depression (0.37) was the highest. However, the transition probabilities from no depression to moderate and severe depression were 0.32 and 0.2,respectively. Latent class analysis identified three types of depressive trajectories: low-stable (1 007 cases with ADL limitations), gradually increasing (1 526 cases), and highly fluctuating (665 cases). Multivariate logistic regression showed that compared with the low-stable group, the risk of ADL limitations was significantly higher in the highly fluctuating group (OR=7.75, 95%CI: 6.54-9.17, P<0.05), followed by the gradually increasing group (OR=2.86; 95%CI: 2.58-3.18, P<0.05).

Dynamic changes in depressive states significantly affect ADL limitations. The group with highly fluctuating depressive trajectories has the highest risk. Clinically, it is necessary to strengthen the monitoring of depressive trajectories and design enhanced interventions for individuals with fluctuating depression to improve functional outcomes.

To evaluate the quality of response reports for non-occupational carbon monoxide poisoning incidents in Shandong Province from 2019 to 2023.

Data were collected from the national “Public Health Emergency Reporting Management Information System” online reporting platform. An indicator system was constructed based on national policy documents and literature analysis, and the weights of indicators were calculated using the Analytic Hierarchy Process (AHP). The quality of the reports was further evaluated using the technique for order preference by similarity to an ideal solution (TOPSIS) method.

The evaluation system consisted of 3 first-level indicators and 11 second-level indicators. The study evaluated a total of 8 612 cases. Temporally, the 2020 emergency response work reports demonstrated the highest comprehensive quality (C_i=0.777), while 2023 showed the lowest (C_i=0.272). At the prefecture-level city tier, Yantai City (C_i=0.778) and Jining City (Ci=0.679) ranked highest. In regional comparisons, the Jiaodong Urban Cluster achieved the best comprehensive quality (C_i=0.596), outperforming both the Provincial Capital Urban Cluster (C_i=0.553) and the Southern Shandong Urban Cluster (C_i=0.359). Evaluation of first-level indicators revealed that the Provincial Capital Urban Cluster excelled in event monitoring and reporting (C_i=0.646) as well as event investigation and handling (C_i=0.566), whereas the Jiaodong Urban Cluster showed significant advantages in post-event performance evaluation (C_i=0.963). The Southern Shandong Urban Cluster exhibited relatively weaker performance across all dimensions.

There are disparities in the performance of the Shandong Province non-occupational carbon monoxide response work report across different years, cities, and regions.

To investigate the epidemiology and influencing factors of pre-treatment drug resistance (PDR) and acquired drug resistance(ADR) in Hebei Province.

Plasma samples were collected from HIV-1-infected individuals who were ART-naive or experiencing ART failure in Hebei Province from January 2022 to December 2023 to determine drug resistance profiles. Multivariate logistic regression was used to analyze the influencing factors of drug resistance.

The overall prevalence of PDR were 9.19%, showing a moderate prevalence trend. The overall prevalence of ADR was 46.71%,presenting a high level of drug resistance and the phenomenon of cross drug resistance. Multivariate logistic regression analysis showed that start ART more than one year after diagnosis (OR=3.007, 95% CI: 1.185-7.633) and being infected with subtypes other than CRF07_BC, subtype B, and URFs (OR=3.227, 95% CI: 1.043-9.991) were risk factors for PDR. Non-farmer occupation(OR=1.787, 95% CI: 1.129-2.830) and 3-5 years treatment duration(OR=2.440, 95% CI: 1.422-4.185) were risk factors for ADR, while CD4+T-cell counts between 200-500 cells/μl (OR=0.382, 95% CI: 0.236-0.618) and above 500 cells/μl(OR=0.158, 95% CI: 0.083-0.299), second-line regimens containing LPV/r or BIC (OR=0.229, 95% CI: 0.083-0.629; OR=0.064,95% CI: 0.008-0.534), and CRF07_BC(OR=0.398, 95% CI: 0.245-0.647) were protective factors for ADR.

Monitoring of local PDR and ADR should be strengthened to know about the situation of drug resistance as early as possible, and targeted interventions should be taken to reduce the spread of HIV-1 drug-resistant strains.

To understand parents’ attitudes towards school food education, explore the impact of school food education on parents’ dietary beliefs, and whether it could have a positive effect on dietary behavior.

A stratified cluster random sampling method was used to collect data from parents whose children are from primary school in grades 3-5 in the food education districts and counties (Pingqiao District and Xin County) and the control county (Shangcheng County) in Xinyang City. A self-administered questionnaire was used to collect information on family background, frequency of food intake, and dietary attitudes and dietary beliefs. The differences between the two groups were compared using t test，χ² test and rank sum test, and the influencing factors of parents’ dietary beliefs were analyzed using a multivariable logistic model.

The survey included 2 601 research subjects, including 1 252 in the food education group and 1 349 in the control group. The proportion of students in the food education group who regularly shared health knowledge was 51.3%, which was higher than that of the control group (33.4%) (P<0.05). In the survey of intake frequency of 7 kinds of foods, the intake of 6 kinds of foods per day in the food education group was significantly higher than that in the control group. The proportion of parents in the food education group who were aware of suggesting their children to drink milk every day was 81.1%, which was higher than the control group's proportion of 66.9% (χ²=67.37, P<0.05). The proportion of the food education group which tried to provide a variety of foods for each meal was 59.8%, which was higher than the control group's proportion of 40.1% (χ²=100.40, P<0.05).

School food education can improve parents’ beliefs of healthy dietary, thereby improving household dietary intake.Children's sharing of health knowledge could play an important role as well.

To assess the level of residents’ sense of gain in basic public health services, analyze its potential categories and influencing factors, and explore the improvement direction in the supply of basic public health services.

Through multistage sampling, 1 383 adult residents who received public health services in Shanxi Province were surveyed by electronic questionnaire in July 2023, and the residents’ sense of gain and its influencing factors were explored based on latent profile analysis.

The average score of residents’ sense of gain in basic public health services on a percentile scale was (59.03±18.17). The residents’ sense of gain in basic public health services could be classified into four categories based on the scores in six dimensions: high sense of gain (37.88%), relatively high sense of gain (33.55%), relatively low sense of gain(15.83%), and low sense of gain (12.73%), and the sense of gain varied among residents with different educational attainment, monthly income and age.

The overall level of residents’ sense of gain in basic public health services is moderately high, indicating that the supply effect of basic public health services is relatively satisfactory. However, in light of the characteristics presented by different categories of residents, managers need to adopt differentiated strategies such as popularizing service projects and its free nature or intensifying precise publicity and education efforts for special groups.
