<p>The connections between bullying and student well-being in rural areas are not well understood, particularly among younger, more vulnerable students. This study aims to explore the relationship between bullying experiences and the academic performance and mental health of primary and junior high school students in rural China. The sample comprised 1609 students from 30 schools (20 primary schools and 10 junior high schools) in Gansu province. A self-report questionnaire was used to collect data on students’ demographics, bullying experiences, mental health, and social support. Additionally, a 30-minute standardized math test was administered to assess academic performance. Results indicated that bullying was prevalent in rural settings, with 42.64% of students reporting being bullied and 12.74% experiencing it weekly. A significant correlation was found between bullying experiences and both lower academic performance and higher risk of mental health problems, such as depression and anxiety. These correlations became more pronounced with increased frequency of bullying incidents. We also found that female students and younger students who were bullied were more likely to report mental health issues. Furthermore, social support could diminish, but not entirely counteract, the adverse associations between bullying and mental health. These findings highlight the prevalence of bullying among rural students in this age group and demonstrate the associated negative outcomes for their mental health and academic performance. They also emphasize the need for targeted attention and the development of intervention programs, including enhanced school-based anti-bullying initiatives and improved social support systems.</p>
