Abstract：This study aims to explore the mediating effect of mobile phone dependence between“weight
anxiety”and depressive symptoms among adolescents，therefore providing a basis for the management and
prevention of adolescent mental health. Electronic questionnaires were distributed in 12 schools from November
2021 to March 2022 using the multi ⁃ stage stratified cluster random sampling method. A total of 9 225
adolescents finished the survey，which included a general questionnaire，a“Weight Anxiety”Questionnaire，a
Self ⁃ rating Questionnaire for Adolescent Problematic Mobile Phone Use，and the Center for Epidemiologic
Studies Depression Scale（CE⁃D10）. The results showed that“weight anxiety”was positively associated with
depressive symptoms（β=0.39，P<0.001）. Mobile phone dependence mediated the relationship between different
manifestations of“weight anxiety”and depressive symptoms，with indirect effects of 14.29% ，14.91% and
22.08% ，respectively. In conclusion，mobile phone dependence mediates the relationship between“weight
anxiety”and depressive symptoms among adolescents. Individuals who are highly concerned about and sensitive
to their body weight may contribute more to this indirect effect.
Key words：weight anxiety；adolescents；depressive symptoms；mobile phone dependence；mediating effect

Abstract：Based on the fundamental reality of China’s aging population and the increasingly severe health
problems among older adults，this study focuses on the health vulnerability of older adults to construct a
structural equation model to investigate the impact of leisure and recreational participation on the health
vulnerability of the older adults based on the data from 2018 Chinese Longitudinal Healthy Longevity Survey
（CLHLS）. The results show that participation in leisure and recreational activities can directly alleviate the
health vulnerability of the older adults and reduce their health vulnerability by improving the self ⁃ assessed
health level. There are multiple intermediary pathways such as“leisure and recreational activity → health
level →physical health vulnerability → mental health vulnerability”. At the same time，participation in leisure
and recreation activities plays a more prominent role in alleviating the physical health vulnerability of urban
older adults. It is more effective in alleviating the mental health vulnerability of the older adults in townships
and rural areas. On this basis，the article proposes to focus on improving the aging construction of urban
regional public leisure places，establishing psychological intervention systems for older adults in townships and
rural areas，and improving the inclusive pension service system，therefore narrowing the gap between urban and
rural areas.
