Lesbian women have a higher risk of depression because they are more likely to have been treated for depression and to have attempted or contemplated suicide than heterosexual women. These higher rates of PPD in lesbian/bisexual mothers may reflect less social support, particularly from their families of origin and additional stress due to homophobic discrimination in society.There is a call to integrate both a consideration of biological and psychosocial risk factors for PPD when treating and researching the illness. Violence
A meta-analysis reviewing research on the association of violence and postpartum depression showed that violence against women increases the incidence of postpartum depression. About one-third of women throughout the world will experience physical or sexual violence at some point in their lives. Violence against women occurs in conflict, post-conflict, and non-conflict areas. The research reviewed only looked at violence experienced by women from male perpetrators. Further, violence against women was defined as "any act of gender-based violence that results in, or is likely to result in, physical, sexual, or psychological harm or suffering  to women". Psychological and cultural factors associated with increased incidence of postpartum depression include family history of depression, stressful life events during early puberty or pregnancy, anxiety or depression during pregnancy, and low social support. Violence against women is a chronic stressor, so depression may occur when someone is no longer able to respond to the violence. Diagnosis
Criteria
Postpartum depression in the DSM-5 is known as "depressive disorder with peripartum onset".
Risk to children
Children that live in a household with a parent that suffers from morbid jealousy may suffer emotional and/or physical abuse as a direct result of the actions made by the parent. Children may also accidentally overhear arguments or witness physical violence between their parents. They could even be potentially accidentally injured during assaults. The morbidly jealous parent may employ a child or more than one to spy on the other parent. It is not out of the question for a child to witness a homicide or suicide where their parent is the victim. See also
