ABSTRACT
Background: With the continuous improvement in economic levels in various countries and the rapid development of the Internet, adolescents' Internet use has become increasingly frequent. Many studies have explored the relationship between Internet use and adolescent health, but the possible mechanisms involved are unclear, and few have focused on Chinese adolescents. Methods: Based on the data from the China Family Panel Studies 2010, 2014, 2016, 2018, and 2020, this study used the ordered probit model and OLS model to explore the impact of Internet use on self-rated health and mental health of Chinese adolescents and analyzed the possible mechanisms and heterogeneity involved. Results: The results revealed that adolescents' Internet use negatively affected their physical and mental health. Parent-child conflict, academic performance, and self-efficacy were the important mechanisms of internet use affecting adolescents' health. Moreover, the negative effects of Internet use on adolescents' physical and mental health were heterogeneous in boarding, mother's education level, and family per capita income. Conclusion: Adolescents exhibit a pattern of using the internet that influences their health status. Our finding that internet use may decrease adolescents' health provides important insights into understanding the relationship between internet use behavior and adolescents' health and suggests that intervention should be taken on adolescents' internet use.
ABSTRACT
Residents play an important role as one of the main actors in food safety governance. To build a pattern of food safety risk co-governance, the positive and effective participation of residents is vital. This study first establishes a comprehensive analysis framework combining social capital theory and political efficacy theory. Data from a survey of 714 residents in Shandong Province, China, were analysed through structural equation modelling and fuzzy-set qualitative comparative analysis (fsQCA) to examine the causal relationship between residents' willingness to participate and its driving factors. The results indicated that: (1) reciprocity norm, institutional trust and social engagement have significant positive effects on willingness to participate; (2) political efficacy has a partial mediating effect in the relationship between social capital and willingness to participate; (3) fsQCA findings have four solutions to achieving residents' strong willingness to participate; reciprocity norm, institutional trust and political efficacy are the core elements that affected residents' high willingness to participate, whereas social engagement and sociodemographic variables are the non-core variables. Therefore, we put forward suggestions for improving residents' willingness to participate in food safety governance, including improving the appeal expression and feedback mechanism, cultivating residents' social capital and paying attention to the superposition effect of social capital and political efficacy.
