•

IPV is an underrecognized problem that occurs in all countries, cultures, and socioeconomic groups.

•

IPV has an enormous impact on personal health, and economic and social well-being.

•

IPV may occur in heterosexual and LGBTQ relationships and may be perpetrated by either sex.

•

Canadian data from 1999 show about equal proportions of men and women had been victims of physical (seven and eight per cent, respectively) and psychological (18 and 19 per cent, respectively) IPV in the previous five years.

•

Exposure to IPV has deleterious effects on children and other family members.

•

Some populations are at greater risk or have special needs for IPV. These include immigrant women, Aboriginal women, LGBTQ communities, people with ALs, pregnant women, dating adolescents, older people, alcohol and other substance abusing people, low-income people, and those without a current partner (that is, IPV perpetrated by a former partner).

•

Mental health problems associated with IPV include depression, anxiety disorders, chronic pain syndromes, eating disorders, sleep disorders, psychosomatic disorders, alcohol and other substance abuse, suicidal and self-harm behaviours, nonaffective psychosis, some personality disorders, and harmful health behaviours, such as risk taking and smoking. As IPV is a major determinant of mental health, it is of vital importance to mental health professionals.

•

Physical health problems associated with IPV include death, a broad range of injuries, reproductive disorders, gastrointestinal disorders, chronic pain syndromes, fibromyalgia, poor physical functioning, and lower health-related quality of life. Sexually transmitted diseases, unwanted pregnancies and physical inactivity are also increased.

•

Children's exposure to IPV may have short- and long-term health impacts on the child, especially mental health effects.

•

Perpetrators of IPV most frequently have personality disorders, but substance abuse and other types of mental illness or brain dysfunction may also occur.
