Abstract Background: Depression is common in women, childhood sexual abuse and its related stigma in our culture are expected to increase the severity of depression, and it may be a strong risk factor for the presence of suicidal ideations in women. This study aimed to look at the relationship of childhood history of sexual abuse and its related stigma to depression and suicidal ideations in depressed women. Methods: A consecutive sample of 160 depressed women was enrolled in this study. The structured clinical interview for DSM-5 was used to diagnose depression, and the Beck Depression Inventory, second edition was used to quantify its severity. The Scale for Suicidal Ideations was used to evaluate suicidal ideations, and history taking was used to assess previous suicidal attempts. The history of childhood sexual abuse was evaluated using a self-report questionnaire, the questions of this questionnaire were derived from the National Population Survey, and a Canadian survey of sexual abuse and its related stigma was assessed using a scale for stigma of sexual abuse. Results: The findings showed that 11.8% of depressed women had a history of childhood sexual abuse under age of 15 years. There was a significant decrease in age of onset of depression, a significant increase in duration of depression, number of hospital admission, the Beck Depression Inventory, second edition BDI-II, the Beck Hopelessness Scale (BHS) mean scores, number of patients with suicidal ideations, and previous suicidal attempts in depressed women with a history of childhood sexual abuse in comparison to those without that history. History of childhood sexual abuse and its related stigma were the most significant predictors for the presence of depression and current suicidal ideations. Conclusions: The history of sexual abuse in childhood and its related stigma were associated with increased severity of depression and the presence of suicidal ideations in depressed women. Identification of childhood sexual abuse and its related stigma in depressed women is highly important for proper management of depression.
