Abstract: Objective To understand the occurrence of emotional and behavioral problems among primary and secondary school students in a county of Yunnan Province and explore potential influencing factors, providing a scientific basis for promoting mental health and developing relevant measures and interventions. Methods In December 2023, a random cluster sampling method was used to select students from the fourth grade of primary school to the third grade of high school in a county of Yunnan Province. The survey tools included the Strengths and Difficulties Questionnaire (SDQ) student version, the MacArthur scale, and a self-designed scale. Binary logistic regression was used to analyze the factors potentially associated with emotional and behavioral problems. Results A total of 830 students were included in this study, comprising 360 boys and 470 girls; 281 primary school students, 266 junior high school students, and 283 senior high school students. The abnormal detection rate of emotional and behavioral problems among students was 11.45% (95 cases), with a borderline rate of 15.30%(127 cases). Logistic regression analysis revealed that family relationships (OR=1.766), parenting style (OR=3.420), and self-evaluation of physical health (OR=0.260, 0.161, 0.077) were significant factors influencing the detection of emotional and behavioral problems (all P< 0.05). Conclusion The prevalence of emotional and behavioral problems among primary and secondary school students in the county is at an intermediate level compared to similar studies, indicating that students in this county may face non-negligible potential emotional and behavioral issues.
