Being scolded by parents, Internet addiction and alcohol consumption were the common factors that had a greater degree of influence on anxiety and depression among secondary school students.

The detection rate of anxiety and depression among secondary school students in Shanxi Province is high, being scolded by parents, alcohol consumption and Internet addiction are the factors that have a greater influence on the occurrence of anxiety and depression, and the random forest model has a high predictive value.

The Perth Alexithymia Questionnaire (PAQ) was translated into a Chinese version of the questionnaire and tested for reliability and validity in adolescents.

The Chinese version of the PAQ scale was formed according to the procedures of forward translation, back translation, cultural adaptation and pre-survey. During February and April 2024, 7 975 adolescents from Shandong Province, Anhui Province, and Hunan Province were selected to test the reliability of the Chinese version of the PAQ. The item analysis was performed using the coefficient of determination and correlation coefficient methods, and the reliability and validity were assessed using confirmatory factor analysis, criterion-related validity, internal consistency reliability, and test-retest reliability. The Toronto Alexithymia Scale, the Patient Health Questionnaire and the Generalized Anxiety Disorder Scale were used as validity scales, and 1 083 adolescents were retested 4 weeks later to determine the reliability of the retest.

The results of the confirmatory factor analysis showed that the Chinese version of the PAQ scale was a 5-factor model (GFI=0.921, NFI=0.938, CFI=0.940, TLI=0.931, RMSEA=0.060). The Cronbach α coefficient for the Chinese version of the PAQ total scale was 0.953. The Cronbach α coefficients for the five subscales of Negative-Difficulty Identifying Feelings, Positive-Difficulty Identifying Feelings, Negative-Difficulty Describing Feelings, Positive-Difficulty Describing Feelings, and General-Externally Orientated Thinking were 0.821, 0.852, 0.807, 0.834 and 0.859, respectively. The retest reliability of the Chinese version of the PAQ scale was 0.762. The retest reliabilities for the five subscales of Negative-Difficulty Identifying Feelings, Positive-Difficulty Identifying Feelings, Negative-Difficulty Describing Feelings, Positive-Difficulty Describing Feelings, and General-Externally Orientated Thinking were 0.717, 0.676, 0.716, 0.709 and 0.692, respectively. The total score of the Chinese version of the PAQ scale was positively correlated with the total score of the Toronto Alexithymia Scale, depressive symptoms, and anxiety symptoms (r=0.782, 0.378, 0.369, P<0.01).

The Chinese version of the PAQ scale showed excellent psychometric properties on all measures in the adolescent population and can be used as an important tool for assessing adolescents’ alexithymia.

To explore the current status of coupled coordination of medical resource supply and service utilization in township health hospitals in Sichuan Province, and to provide reference for optimizing medical resource allocation.

The data concerning the allocation of health resources and the utilization of services in township health centers of various cities (prefectures) in Sichuan Province from 2017 to 2021 were selected. The comprehensive evaluation index was utilized to comprehensively assess the allocation of health resources and service utilization, and the coupling coordination degree model was employed to analyze the relationship between the two systems.

The comprehensive evaluation index of medical resource supply and service utilization in township health centers in Sichuan Province improved from 0.27 and 0.45 in 2017 to 0.30 and 0.52 in 2021, respectively, and more than 90% of the areas were subject to lagging medical resource supply; the type of coupling coordination ranged from reluctant coupling coordination to primary coupling coordination; reluctant coordination was the main type; and the LISA chart showed Aba as the "high - high" aggregation point, Luzhouwas low - low aggregation point.

The level of resource supply and service utilization and coupled coordinated development of township health centers in Sichuan Province has been increasing, and the level of health resource supply and service utilization has not been synergistically developed, and most of them are subject to the lagging supply of health resources, and there is a localized aggregation effect of the degree of coupled coordination in space.

To investigate the relationship between social alienation and health promotion behaviors in community chronic co-morbid older adults, and explore the mediating role of self-perceived aging.

Using the convenience sampling method, A questionnaire survey was conducted using the General Information Questionnaire, the General Alienation Scale, the Simplified Self-perceived Aging Scale, and the Health Promoting Lifestyle Scale on 611 community-based older adults with chronic co-morbidities in Hangzhou, and structural equation modeling was constructed using AMOS.

The total score of chronic co-morbid social alienation in the community was (36.38±10.41) points, the total score of self-perceived aging was (50.10±14.68) points, and the score of health promotion behavior was (93.79±15.56) points. The results of the mediation effect test showed that the effect value between social alienation and health promotion behavior was -0.205 (95%CI: -0.285 to -0.121), accounting for 45.86% of the total effect; the effect value of self-perceived aging in the mediation effect between social isolation and health promotion behavior was -0.242 (95%CI: -0.299 to -0.191); the total effect value was -0.447 (95%CI: -0.508 to -0.383), and the mediation effect accounted for 54.14% of the total effect.

Social alienation and self-perceived aging of chronic co-morbid older adults directly affect health promotion behaviors, while social alienation can indirectly affect health promotion behaviors through self-perceived aging.

To explore the potential categories of health literacy of the elderly with chronic disease comorbid disability and their relationship with family nursing quality.

713 comorbid disabled elderly in Urumqi, Xinjiang were investigated by general data, function of daily living index, health literacy scale for chronic disease patients and Family Care Quality Scale for disabled elderly (FCCI). Mplus 8.3 was used to make potential profile analysis of their health literacy, and SPSS 26.0 software was applied. To compare the quality of family care for the elderly with comorbidity and disability in different categories of health literacy.

The health literacy of the elderly with concomitant disabilities can be divided into three categories:high health literacy - high willingness (35.5%), medium health literacy - good acceptance (47.7%), and low health literacy - low access to information (16.8%). There were significant differences in the total score of family care quality and the scores of each dimension among the 3 different health literacy groups (P<0.001). The total score of family care quality in the group with high health literacy and high willingness was the highest (47.47±0.128), and the total score of family care quality in the group with low health literacy and low information access was the lowest (40.28±0.315). The scores of family care quality in the group with high health literacy and high willingness were higher than those in the other two groups, including scores of disabled elderly (28.03±0.053), caregiver (11.02±0.054) and family members (8.42±0.062). The scores of family care quality in the group with low health literacy and low access to information were lower than those in the other two groups, including scores of disabled elderly (24.78±0.176), caregiver (8.97±0.116) and family members (6.53±0.101).

There are three potential categories of health literacy for the elderly with comorbid disabilities, and the quality of family care for the elderly with comorbid disabilities is different in different potential categories. It is suggested that targeted personalized intervention programs should be developed based on the groups with the same health literacy of the elderly with comorbid disabilities, so as to improve the quality of their family care.

To explore the potential categories of primary caregiver burden in families of cancer patients and their potential related factors, and to provide scientific basis for more targeted policy interventions.

From February to April 2023, we conducted a questionnaire survey among the primary family caregivers of cancer patients at the Third Affiliated Hospital of Harbin Medical University using convenience sampling. Latent profile analysis was employed to identify potential categories of caregiver burden. The modified BCH method was used to assess the differences in family resilience, individual resilience, and caregiving ability across different burden categories.

A total of 367 participants were included in the study, and their caregiving burden was divided into two categories, named "mild caregiver burden group" and "moderate and severe caregiver burden group". The respondents of "moderate to heavy caregiver burden" were mostly female who were highly educated and had spouse and children. Different potential categories of family caregiver burden profiles showed statistically significant differences in family resilience (χ²=5.333，P=0.021), individual resilience (χ²=31.687，P<0.001), and caregiving ability (χ²=13.391，P<0.001).

There are heterogeneous subgroups of primary caregiver burden in families of cancer patients, and policy makers should implement targeted interventions to reduce the burden of primary caregivers for families with cancer patients, and to improve their personal and family resilience and caring abilities.

To understand the utilization and demand status of cancer screening services among residents in Sichuan Province, and provide scientific basis for further promoting cancer screening strategies.

Using multi-stage stratified clustering and probability proportional to size (PPS) sampling, a face-to-face questionnaire survey was conducted among 15-74-year-old permanent residents from 10 cities (prefectures) in Sichuan Province. Using chi-square test for univariate analysis of cancer screening service utilization and demand, and using logistic regression model for multivariate analysis.

A total of 7 442 valid questionnaires were collected, with an effective rate of 91.30%. 1 099 residents (14.77%) had undergone cancer screening, aged between 40 and 60 years old (OR=1.62, 95%CI:1.31-2.00), female (OR=1.92, 95%CI:1.65-2.25), married, with a college/undergraduate education or above, civil servants and public institution staff (OR=1.59, 95%CI:1.20-2.09), with a family history of cancer, urban household registration (OR=1.46,95%CI:1.23-1.74), poor self-rated health status, and higher utilization rate of cancer screening services for urban employees with basic medical insurance.5034 residents (67.64%) had a demand for cancer screening services. Married individuals with higher education levels, total household income ≥ 60000 yuan/year (OR=1.20,95%CI:1.07-1.35), family history of cancer, and poor self-rated health status had a higher demand for cancer screening services.

There is a high demand for cancer screening services among residents in Sichuan Province, but the actual utilization is insufficient. It is recommended to improve and promote cancer screening work by strengthening health education and establishing a multi-channel funding mechanism for cancer screening.

To investigate the mediating effects of daily activity ability and depression on pain status and subjective life expectancy in elderly patients with chronic diseases, and to provide suggestions and references for active aging.

Based on The China Health and Retirement Longitudinal Study (CHARLS) 2020 data, 5 768 patients with chronic diseases aged ≥60 years were selected as the study subjects, and Spearman correlation analysis was used to explore the correlation between pain, ability to perform activities of daily living, depression, and subjective life expectancy, and PROCESS 4.1 program Model 6 was used to construct the chain-mediated model.

Pain was positively correlated with impaired daily activity ability and depression (r=0.399, P<0.001; r=0.370, P<0.001), was negatively correlated with subjective life expectancy (r=-0.221, P<0.001); The mediating effects of daily activity ability and depression on pain and subjective life expectancy were significant, with simple mediating effects of -0.023 (95%CI: -0.031 to -0.016) and -0.042 (95%CI: -0.049 to -0.034), respectively. The chain mediation effect was -0.013(95%CI: -0.016 to -0.010). The total mediating effect of daily activity ability and depression on pain and subjective life expectancy was -0.078, accounting for 57.78%.

There is a chain mediated effect between daily activity ability and depression on pain status and subjective life expectancy in elderly patients with chronic diseases. With the popularization of primary medical and health services, the family doctor service team needs to improve the comprehensive management of elderly patients with chronic diseases, improve the subjective well-being of elderly patients with chronic diseases from pain management, daily activity intervention, depression regulation and other aspects, and prolong the subjective life expectancy.

To explore the impact of social participation on cognitive decline in middle-aged and elderly people, and to provide a reference for improving or maintaining the cognitive health of middle-aged and elderly people.

A total of 6 645 middle-aged and elderly people over 50 years old in the 2018 China Longitudinal Survey on Influencing Factors of Elderly Health (CLHLS) were selected as the research subjects, and cognitive frailty was evaluated by the Mini-Mental State Evaluation Scale (MMSE) and Frailty Index (FI). A multivariate logistic regression model was used to analyze the effects of social participation type and intensity on cognitive weakness.

The higher the participation of middle-aged and elderly people in family activities, individual activities, and group activities, the lower the incidence of cognitive weakness. High participation in family activities had the highest effect on mild (OR=0.271, 95%CI:0.228-0.321), moderate (OR=0.463, 95%CI:0.361-0.592) and severe (OR=0.079, 95%CI:0.043-0.146) cognitive frailty. The incidence of cognitive frailty was negatively moderated by high participation in family activities (OR=2.263, 95%CI:1.579-3.244), and the incidence of cognitive frailty was negatively moderated by urban middle-aged and elderly people in group activities (OR=0.459, 95%CI:0.289-0.727) and high participation (OR=0.490, 95%CI:0.331-0.725).

It is of great significance to increase the enthusiasm of middle-aged and elderly people for social participation, especially family activities, to delay the decline of cognitive frailty.

To investigate the intrinsic relationships among family functioning, life events and insomnia in adolescents with depression.

A survey was conducted on 165 adolescents diagnosed with depression who were receiving treatment at a tertiary hospital in Guangzhou. The study utilized a general information questionnaire, Family APGAR Index, Insomnia Severity Index, and Adolescent Life Events Scale. Descriptive and correlation analyses were performed using SPSS, and mediation effects were tested using the Process plugin.

The insomnia rate among adolescent depression patients was 77.58%. There was a significant positive correlation between insomnia and the total score of life events and its dimension factors (P<0.01), while insomnia showed a significant negative correlation with the total score of family functioning and its dimension factors (P<0.01). The results of the Bootstrap test indicate that family care, growth factors and cooperation play a partial mediating role between life events and insomnia in adolescent depression patients (β=0.019, 95% CI: 0.003-0.036; β= 0.013, 95% CI: 0.01-0.026; β= 0.011, 95% CI: 0.000-0.024), accounting for 15.45%, 10.57% and 8.94% of the total effect, respectively.

Adolescents with depression experience moderate to high levels of insomnia. Life events in adolescents with depression can directly affect insomnia, or indirectly influence it through family care.
