Violence, depression, and suicidal ideation represent interconnected public health challenges affecting women and adolescents globally, particularly in low-resource settings. This study provides an integrated assessment of these factors across multiple populations, including adult women and adolescent girls, using a comparative cross-sectional framework. Drawing on synthesized empirical data, the study examines the prevalence and interrelationships between exposure to violence, depressive symptoms, and suicidal ideation. Findings indicate that exposure to violence significantly increases the likelihood of depression, which in turn elevates the risk of suicidal ideation. Evidence suggests that suicidal ideation among pregnant women ranges from approximately 2 percent to over 14 percent depending on context, with substantially higher rates observed among vulnerable adolescents. Adolescent populations, particularly pregnant adolescents, demonstrate markedly higher prevalence rates, with some studies reporting rates exceeding 28 percent. Depression consistently emerges as a central mediating factor linking violence to suicidal ideation. Socioeconomic disadvantage, weak social support systems, and limited access to mental health services further intensify these risks. The study proposes an integrated socio-ecological framework for understanding these relationships and emphasizes the need for multi-level interventions. The findings contribute to the development of comprehensive strategies aimed at reducing mental health disparities and improving outcomes for vulnerable populations.
