Objective:
To explore the network structure of anxiety and depressive symptoms, and psychotic like experiences in junior and senior high school students with different sleep qualities, and to provide a reference for improving sleep quality in the population.
Methods:
A cross sectional online survey was conducted among 22 997 junior and senior high school students from seven junior and senior high schools in Luzhou City, Sichuan Province, using convenience sampling. The Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and the 16item Prodromal Questionnaire (PQ-16) were administered. Independent sample t-test was used to compare mental health status between adolescents with and without sleep problems. Network analysis was applied to examine the symptom association patterns across gender and school stage subgroups.
Results:
The prevalence of sleep problems among junior and senior high school students was 22.58%. The total anxiety symptom score (8.92± 4.02 ), total depressive symptom score (13.35±5.66), and scores for each factor of PQ-16 (perceptual and sensory abnormalities, thinking abnormalities, negative symptoms, and specific perceptual and sensory abnormalities) (3.32±3.32, 2.08±2.36, 3.36± 2.74 , 1.44±1.86) in the group with sleep problems were all significantly higher than those in the group without sleep problems ( 3.43 ±3.33, 5.03±4.73; 0.63±1.52, 0.47±1.11, 0.77±1.48, 0.25±0.79), with statistically significant differences ( t =99.60, 106.54, 82.49, 68.51, 89.09, 67.30, all P <0.01). In females with sleep problems, the anxiety-depressive symptoms edge weight was the highest (0.44). In males with sleep problems, the "sleep latency-sleep efficiency" edge weight was the highest (0.43), and the strength centrality values of "perceptual abnormalities" "medication factor" and "sleep latency" ranked the higher (1.32, 1.31 and 1.25). The network connectivity strength of the sleep problem group was higher in senior high school students than in junior high school students, and the strength centrality (1.12) and betweenness centrality (0.12) of negative symptoms were higher than those in junior high school students (1.02 and 0.11).
Conclusions
The network associations between sleep problems and psychological symptoms in junior and senior high school students exhibit gender and school stage specific characteristics. Differentiated intervention strategies should be tailored to specific subgroups.

BackgroundIn recent years, the prevalence of obstructive sleep apnea (OSA) is escalating in China, leading to a serious disease burden. However, previous studies on the influencing factors of OSA, such as obesity and sleep position, were mostly cross-sectional studies. This approach inherently hinders the identification of dynamic interaction mechanism among multiple variables, consequently obstructing the formulation of individualized intervention strategies. ObjectiveTo investigate the differences in body mass index (BMI)-oxygen saturation-sleep position-heart rate variability (HRV) network models between OSA and non-OSA populations, thereby offering a reference for the early detection and management of OSA. MethodsA total of 384 adult participants undergoing sleep monitoring at the Affiliated Hospital of Southwest Medical University from July 12, 2022 to October 11, 2023 were included. Subjects were categorized into OSA group (n=203) and control group (n=181) based on an apnea-hypopnea index (AHI) threshold of 5 events per hour. Subsequently, BMI-oxygen saturation-sleep position-HRV networks were constructed and compared between two groups. ResultsThere was no significant difference in the overall edge weight (P=0.55) and overall strength (P=0.28) of the network model between control group and OSA group. Notable differences emerged in both the node connection strength (e.g., minimum oxygen saturation with BMI, sleep in prone position, and mean RR interval) and node centrality indices (mean oxygen saturation, minimum oxygen saturation, AHI in upright position, AHI in right lateral position and mean heart rate) within the two network models (P<0.05). ConclusionSignificant differences are observed between the non-OSA and OSA populations in specific factors, including sleep position, heart rate and oxygen saturation.

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden, which has garnered significant national attention and prompted their inclusion in public health project management systems. However, credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City, Sichuan Province, remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City, Sichuan Province, and to analyze influencing factors of disease stabilization among patients under standardized care, so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023, data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City, the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017, respectively, which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022, the regular medication adherence rate was 71.80% for schizophrenia, 55.26% for paranoid psychosis, and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization: age of 18~39 years (OR=0.613, 95% CI: 0.409~0.918), age of 40~65 years (OR=0.615, 95% CI: 0.407~0.931), urban residence (OR=0.587, 95% CI: 0.478~0.720), and regular medication adherence (OR=0.826, 95% CI: 0.702~0.973). Risk factors for disease fluctuation included poor (OR=1.712, 95% CI: 1.436~2.040), non-inclusion in care-support programs (OR=1.928, 95% CI: 1.694~2.193), non-participation in community rehabilitation (OR=2.255, 95% CI: 1.930~2.634), and intermittent medication adherence (OR=3.893, 95% CI: 2.548~5.946). ConclusionThe stability rate, standardized management rate, and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age, household registration status, economic condition, medication compliance, and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients.
