Abstract
INTRODUCTION: Suicide is the second leading cause of death among adolescents worldwide. Suicidal ideation (SI) in adolescents may be influenced by factors such as resilience, anxiety, and depressive symptoms. The COVID-19 pandemic served as a significant stressor with documented impacts, yet further research is needed to clarify its effects. While stressful events are known to be associated with increased SI, direct evidence linking COVID-19 specifically to elevated SI remains limited. OBJECTIVE: The aim of this study was to identify the risk and protective factors associated with SI in Mexican adolescents during the COVID-19 pandemic. METHOD: A cross-sectional, correlational descriptive study was conducted between May and June 2022 with a sample of 2,194 high school students, with a mean age of 16.6 years (SD = 1.2). Among the participants, 58.9% were female and 41.1% were male. They completed inventories to assess stress, anxiety, depressive symptoms, and resilience. RESULTS: Of 2194 adolescents, 15.5% presented SI, with females showing a higher prevalence of SI, anxiety, and depressive symptoms compared to males. In contrast, resilience was lower in females. Furthermore, depressive symptoms were identified as a risk factor for SI (OR 1.212; 95% CI 1.186, 1.240), whereas social competence was highlighted as a protective factor (OR 1.046 95% CI 1.044, 1.078). CONCLUSIONS: The findings underscore the importance of preventing SI in adolescents by addressing anxiety and depressive symptoms, which were identified as risk factors, and by promoting social competence as a protective factor. Therefore, an integrated approach that addresses both individual mental health and the social context must be considered for preventing SI in adolescents.
