Background: Adolescence is a critical period for physical and mental health development. Chinese adolescents face multiple challenges such as academic pressure, with considerable mental health risks. Positive health behaviors are closely associated with physical and mental health, but their complex interaction network remains unelucidated.

Methods: Cross-sectional survey was conducted on 436 middle school students with positive health behavior scale and SCL-90. The network of 15 nodes (10 mental health symptoms and 5 positive health behaviors) was constructed by network analysis. The stability of the network was tested by correlation stability analysis. The core nodes were determined by centrality index. The cross-system association strength was analyzed by bridge effect expectation (BEI).

Results: The network showed robust stability (CS coefficient = 0.75). Anxiety was the core node in mental health symptoms, positively correlated with somatization (r = 0.26) and hostility (r = 0.22). Circadian self-regulation was positively correlated with psychopathology (r = 0.52). Physical activity served as a cross-system bridge, negatively correlated with depression (r = -0.08). No significant gender differences in network characteristics were observed.

Conclusion: Adolescent positive health behaviors and mental health form a complex association network. Anxiety is a core driver of psychological symptoms, and physical activity is a key cross-system bridge for improving mental health. The findings provide a theoretical basis for developing targeted intervention strategies focusing on physical activity.

Background: Informal caregivers, frequently family members or close acquaintances, offer uncompensated care and support to individuals with cardiovascular diseases, confronting diverse challenges such as mental stress, financial strain, and the overall burden of care. Addressing these challenges is vital for both caregivers and patients. This systematic review seeks to identify the factors contributing to caregiver burden among informal caregivers of cardiovascular patients.

Methods: PubMed, Scopus, ProQuest, Web of Science, and Science Direct were searched from 2000 until July 2023, following the PRISMA guidelines, to systematically retrieve relevant papers. The review incorporated quantitative, qualitative, and mixed-methods studies.

Results: Forty-two studies were included in the systematic review. Data synthesis adhered to the Joanna Briggs Institute (JBI) methodological guidance using a convergent integrated approach. Five categories emerged: individual characteristics (demographic characteristics of the caregiver and patient-related factors), confronting multifaceted tensions (physical problems, mental health problems, and financial burden), role strain in daily life, inadequate health literacy, and lack of support.

Conclusion: This review underscores that informal caregivers of cardiac patients encounter substantial burdens. These burdens are intensified by challenges, including insufficient knowledge, restricted social support, and suboptimal communication from both family members and healthcare providers, resulting in increased physical and psychological stress. It is crucial to evaluate informal caregivers for these burdens and offer the required support. Clinical implications include routine assessment of caregiver burden, providing tailored educational interventions to enhance health literacy, and offering financial and psychosocial support to mitigate risks specific to cardiovascular disease caregiving.
