[Effect of Family Function on Suicide-Related Behaviors of Junior Middle School Students: The Mediating Effect of Depression].

Objective: To examine the prevalence of suicide-related behaviors among junior middle school students, and to explore the mediating role of depression in the relationship between suicide-related behaviors and family function. Methods: A total of 2572 junior middle school students from three middle schools in Chengdu were interviewed face-to-face by using suicide-related items from Youth Risk Behavior Surveillance System (YRBSS), Chinese Family Assessment Instrument (C-FAI), and Center for Epidemiologic Studies Depression Scale for Children (CES-DC). The mediating role of depression was analyzed with structural equation model. Results: The prevalence of suicide-related behaviors was 26.01% among the respondents. The prevalence of suicide ideation, suicide plan and suicide attempt were 24.38%, 13.49% and 10.77%, respectively. Depression played a partial mediating role in how family function impacted on suicide-related behaviors, presenting a direct effect value of 0.170 (95% CI: 0.117-0.218, P<0.001) and an indirect effect value of 0.205 (95% CI: 0.176-0.234, P<0.001), with the mediating effect accounting for 54.67% of the total effect. Conclusion: Poor family function may increase the risk of suicide-related behaviors, and this effect is produced mostly through the impact on children's mental health. Improving family function will not only improve children's psychological status, but also reduce suicide-related behaviors.

[Analysis of Nursery Services for Children under 3 in Sichuan Province Based on the Theory of Supply and Demand Adaptability].

Objective: To analyze the supply and demand adaptation of nursery care services for children under 3 in Sichuan Province and to provide strategic suggestions for optimizing nursery care services in Sichuan Province. Methods: Data on the supply and demand of nursery school services in all 21 cities (prefectures) of Sichuan Province were collected with questionnaires for nursery care institutions and family needs questionnaires. Applying the theory of supply and demand adaptability, we analyzed the adaptability of nursery care services in Sichuan Province in four dimensions, including relevance, adaptability, accessibility and quality. Results: A total of 6883 valid institutional questionnaires and 41081 valid family questionnaires were collected. The analysis of the adaptability of supply and demand showed that there was insufficient adaptability in all four dimensions of relevance, adaptability, accessibility, and quality of nursery care services for children under 3 in Sichuan Province, which was characterized by the coexistence of insufficient supply and underutilization of services, the mismatch between the structure of services provided and the needs of families with children under 3, low economic accessibility for the general population, and low quality of services. Conclusion: There is insufficient adaptability in the supply and demand of nursery care services for children under 3 in Sichuan Province. Demand-oriented supply-side reforms should be implemented to promote the construction of a system of government-subsidized affordable nursery care services, reinforced support for the care of infants and toddlers for families, standardized management of infant and toddler care institutions, and the implementation of various supportive policies so as to comprehensively meet the diversified needs of infant and toddler care and promote their healthy growth.
