Understanding the intricate interconnection between social capital and self-rated health among Chinese adolescents is of paramount importance in the broader context of public health research (Gu & Zhu, 2020; X. Y. Hu & Hu, 2021; Novak et al., 2018; Pan & Wu, 2020; Zhu et al., 2019). Adolescence, characterized by dynamic psychosocial and physical development, is a crucial period in which social influences play a crucial role in shaping health perceptions. Examining the relationships between the various dimensions of social capital — particularly in the context of family, neighborhood and school — and self-rated health provides valuable insights into the nuanced factors that contribute to adolescents' well-being.
The family unit, considered the cornerstone of social structure during adolescence, has a significant impact on various aspects of adolescent development, including the formation of personal values, coping mechanisms, and social support networks. This study, which examines the nuanced interplay between family dynamics and self-rated health among Chinese adolescents, provides results that are consistent with expected outcomes. Specifically, a significant association was found between good self-rated health and increased family social capital (OR 2.99; 95% CI: 1.78 to 5.00). These findings align with the existing literature on this topic and support existing perspectives. In line with the work of Boele et al. (2023), Botelho Guedes et al. (2022) and Pechmann et al. (2020), this study confirms the recognized importance of family influence on adolescent well-being. The family, which serves as the primary context for the development of social bonds and emotional security, is of particular importance for health perceptions. Echoing the sentiments expressed by Lin & Yi (2019) and Seay et al. (2023), the results of this study highlight the enduring influence of family relationships on adolescents' psychosocial development. This emotional resilience and support contribute significantly to positive health outcomes as adolescents navigate the challenges and transitions characteristic of this stage of life. The role of the family as a crucial support system is particularly evident in Chinese culture, where strong family ties are deeply rooted. Furthermore, these results are consistent with cross-sectional studies such as that of Bamford et al. (2023), which emphasizes the universal importance of family relationships for adolescent health. Understanding the multifaceted impact of family on adolescents health therefore not only enriches the scientific discourse, but also emphasises the importance of targeted interventions that strengthen family connections for the overall well-being of Chinese adolescents."
Together with family influence, the immediate neighborhood environment proves to be a decisive social factor during adolescence that can either strengthen or hinder adolescents' health. In this study, the complex relationship between neighborhood social capital and self-rated health among Chinese adolescents is seamlessly consistent with the expected results. In particular, a significant correlation in which good self-rated health is associated with increased trust in the neighborhood was observed (OR 1.85; 95% CI: 1.13 to 3.04). The results were not surprising, as the sense of trust, support and cohesion within a neighborhood fosters a supportive environment and gives adolescents a sense of belonging and security. This positive social capital helps to reduce stress levels, improve mental health and increase the likelihood of engaging in health-promoting behaviors. In addition, the informal social control mechanisms within a well-connected community can positively influence health outcomes. The shared sense of responsibility and mutual support in the neighborhood can lead to a positive feedback loop that promotes the individual and collective well-being of Chinese adolescents. Consistent with studies such as that conducted by Novak et al. (2015b, 2016), the findings of this study highlight the universal importance of neighborhood relationships in shaping adolescent health. These studies not only increases the robustness of this study’s results, but also demonstrates that the influence of neighborhood dynamics on health perceptions transcends cultural boundaries. This study aligns with the perspectives presented by Aspillaga et al. (2022) and Marquez et al. (2023), who emphasize the role of social capital in community health. The observed positive association between good self-rated health and increased trust in the neighborhood is consistent with the theoretical framework proposed by these authors. In addition, the findings obtained from this study are consistent with the findings of (Marquez, Qualter, et al., 2023; Shareck et al., 2023), who further emphasize the positive association between neighborhood social capital and individual health outcomes. The association between good self-rated health and increased trust in the neighborhood uncovered in this study’s results points to a potential avenue for positive health interventions. This highlights the potential effectiveness of strategies aimed at strengthening community cohesion and trust.
This study takes a different turn when it looks at the area of school social capital. Surprisingly, a statistically significant correlation in these results was not found, which deviates from expectations and prompts further reflection. This result is in contrast to the expected role of school social capital, which is often considered crucial for adolescents' health perceptions. To understand this result, it is important to examine the reasons for the lack of a statistically significant relationship. In contrast to this study, the results seem to contradict the findings of other authors. For example, the research presented by Buerger et al. (2023), Cilar et al. (2020), Pechmann et al. (2020b), Rudolf & Lee, (2023) and M. Yuen & Wu (2023b) indicates a strong positive correlation between school social capital and self-rated health in adolescents. However, the results of this study paint a different picture, as no statistically significant correlation was found. This deviation from expectations underlines the complexity of social capital at school level and the fact that different factors can manifest themselves differently in different environments. Possible reasons for the lack of correlation in this study could be differences in the socioeconomic background of the study participants, different perceptions of social capital among students, or unique contextual factors influencing the school environment. In addition, the complexity of building and maintaining social capital in the school environment as well as the role of individual personalities and social dynamics could contribute to the observed deviation from the expected correlations. To fully decipher the complex relationships, future research should consider a qualitative approach to examine students' life experiences and the qualitative aspects of social interactions in the school context.
Nevertheless, this study is subject to certain limitations. Firstly, the regional differences in socio-economic, cultural and educational development in China may affect the generalizability of the results. Beijing, as the capital, has a relatively high level of socio-economic and cultural development, which contributes to the overall higher socio-economic status of families. However, there are differences between the 16 districts and the different high schools in Beijing. To increase the representativeness of the sample size, future studies should consider greater geographical diversity and conduct more comprehensive analyses. Second, the self-reported family socioeconomic status and health assessments of high school students are susceptible to individual perception bias. The ongoing effects of the Covid-19 pandemic further complicate the matter, as a noticeable decline in community and school-organised activities affects students' self-assessment of their health. In further research projects, a broader and more diverse group of participants combined with a differentiated investigation of contextual influences would be essential for a more thorough understanding of the complex relationships.
