We know that mental health disorders among women and girls are prevalent in Canada. When someone begins to have mental health problems, it can significantly reduce one's well-being and quality of life. Mental health problems can persist across the lifespan, as well as create a substantial burden on society. Over time, mental health problems can worsen and lead to mental disorders, substance use problems, thinking about suicide, and attempting suicide. Mental disorders can be hard to treat, and wait times for treatment can be long. Overall, access to mental health care in Canada is limited and often inequitable.
If we want to make large gains in improving mental health among women and girls in Canada, we need to focus on prevention and understanding the role that violence plays on poor mental health. Violence prevention is critical for improving mental health in Canada among women and girls.
For some children, their first exposures to violence is in the home. We don't have good Canadian data to tell us how many parents spank or hit their children. However, we do know that hitting children as a means of physical discipline is common. We also know that there is conclusive evidence across decades and thousands of studies that indicate that spanking is related to poor outcomes, including mental disorders, substance use problems, and thinking about and attempting suicide in childhood and across the lifespan. Children who are spanked are also more likely to experience severe physical abuse, sexual abuse, emotional abuse, and exposure to intimate partner violence.
Our team analyzed data from nationally representative samples of Canadian adults who retrospectively reported on their childhood experiences. We found that among women, 21% experienced physical abuse, 14% experienced sexual abuse, and 9% were exposed to intimate partner violence. Overall, 30% of women in Canada have experienced physical abuse, sexual abuse, and/or exposure to intimate partner violence.
Sex differences were noted, with women compared to men being less likely to be physically abused and more likely to be sexually abused and exposed to intimate partner violence. Gender-based violence is an important consideration when understanding the mental health of women and girls.
We further analyzed the data and found that individuals who experienced physical abuse, sexual abuse, and exposure to intimate partner violence were more likely to have depression, bipolar disorder, generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, post-traumatic stress disorder, phobias, attention deficit disorder, eating disorders, alcohol abuse and dependence, drug abuse or dependence, thinking about suicide and also attempting suicide.
Importantly, other research has shown that those who experience violence in childhood are also more likely to experience violence in intimate partner relationships in adolescence and adulthood. For some, violence may also continue across generations when children who were abused in childhood grow up, become parents, and continue the same patterns with their own children.
We know that violence is not the only reason why people develop mental disorders. Genetics, environment, and other experiences are important contributors to mental disorders. However, our research team hypothesized that childhood adversity played an important role in understanding who was more likely to have a mental disorder.
To test this hypothesis, our team used data from the United States and computed statistical models that were designed to estimate what proportion of mental disorders and suicidal behaviours in the general population could be attributed to experiencing child abuse. In other words, the statistical modelling estimated how much mental disorders and suicidal behaviour prevalence might be reduced in the general population if the child abuse did not occur.
What we found was that if physical abuse, sexual abuse, and exposure to intimate partner violence could be eliminated, then it is estimated that mental disorders among women might be reduced by approximately 22%-32% in the general population. Suicidal thoughts may be reduced by approximately 16% among women, and suicide attempts among women may be reduced by about 50% in the general population. Even if we couldn't prevent all child abuse, making gains to reduce child abuse would likely correspond with dramatic increases in the reduction of mental disorders in Canada over time.
Of course, we can't focus on prevention alone. We also need to invest in evidence-based treatments for mental disorders, substance use problems, and suicidal thoughts and attempts. We need to reduce wait times for care and provide better access to treatment for all Canadians. An improved and targeted combined intervention and prevention approach is needed.
If we want significant improvements in mental health, we need to work towards reducing all types of childhood violence, including spanking. Preventing childhood violence is difficult but possible, and it is critical for better mental health outcomes among women and girls in Canada.
Thank you.
