TORONTO – One in three adult Canadians suffered some form of child
abuse in their past, experiences that put them at a higher risk of
developing mental health disorders later in life, a new study reports.
The data paint the first nationwide picture of the prevalence of
child abuse experienced by Canadian adults, lead author Tracie Afifi
said of the study, published Tuesday in the Canadian Medical Association
Journal.
She and her co-authors analyzed information collected from more than
23,000 adults 18 and older who took part in Statistics Canada’s 2012
Canadian Community Health Survey. Respondents were asked questions about
whether they were hit or subjected to other forms of physical or sexual
abuse in childhood, or whether they were exposed to violence between
the adults in their homes.
They were also asked whether they suffered from a variety of mental
health disorders, including depression, bipolar disorder, alcohol or
drug abuse as well as whether they thought about or had attempted
suicide.
The researchers found a strong correlation between experiencing abuse
in childhood and having mental health disorders in adulthood.
“Even when we looked at what’s most minor and what some people today
would still argue is not abuse, those are still related right across the
board with strong effects for all the mental conditions we looked at,”
said Afifi, associate professor in the department of community health
sciences at the University of Manitoba.
“As a Canadian, I find the number to be very large and alarming. As a
child maltreatment researcher, that’s the number I expected to see.”
The findings didn’t surprise Dr. Suvercha Pasricha either. The lead
physician of the women’s inpatient unit at the Centre for Addiction and
Mental Health in Toronto, Pasricha sees the effects of childhood abuse
daily in the patients she treats.
“These are all the behaviours children learn as ways of coping with
their distress when they grow up in traumatic environments,” she said,
listing off the conditions — such as eating disorders — the study found
are associated with childhood abuse.
“They turn into disorders as they get older.”
Afifi said previous estimates of child abuse rates in Canada were
based on a nearly 25-year-old study from Ontario and more recent data
from Quebec.
For this study, people were not asked directly if they were abused.
Afifi said studies have shown that some people who have been abused
don’t characterize their experiences as such.
Instead, the questions asked whether respondents were slapped on the
face or head, spanked with a hard object or were pushed, grabbed, shoved
or had something thrown at them to hurt them. For both those questions,
respondents were asked to say yes only if the behaviour had happened a
minimum of three times.
Another question asked if respondents were kicked, bit, punched, choked, burned or physically attacked at least once.
Sexual abuse questions were designed to determine whether respondents
were forced into unwanted sexual activity. And the questions related to
having witnessed intimate partner violence asked whether as children
they had seen their parents, step-parents or guardians hit each other or
other adults in the home three or more times.
One in three adults reported experiences that met the criteria for at
least one of the types of abuse, with physical abuse the most common of
the three; 26 per cent of respondents said they had experienced
physical abuse.
Ten per cent of respondents said they had experienced sexual abuse
and nearly eight per cent witnessed intimate partner violence.
Men were more likely than women to have experienced physical abuse,
31 per cent versus 21 per cent. But women were more likely to have
experienced sexual abuse, 14 per cent versus nearly six per cent. There
was little difference in the rates of people who reported seeing
intimate partner violence — nine per cent of women, seven per cent of
men.
When the researchers looked to see if people who had experienced
abuse were more likely to suffer from mental health disorders in
adulthood, they found strong evidence of a link. (This type of study
cannot prove cause-and-effect; it can only point to possible
associations.)
People who reported experiencing all three types of abuse were 27
times more likely to have attempted suicide, 17 times more likely to
have post-traumatic stress disorder and nearly 11 per cent more likely
to have a drug dependency or an eating disorder.
Even those who had experienced only one type of abuse were between
nearly two and four times more likely to have one or some of the various
disorders.
The authors said it is critical to raise awareness of the issue so that prevention strategies can be devised and implemented.
“From a public health perspective these data alert us to the need to
prevent all of these acts from happening on children today, which may
also help to reduce the poor mental health in the next generations,”
Afifi said.
Pasricha agreed. She said just as salt intake affects the risk of
high blood pressure, exposure to trauma raises the risk of mental health
disorders.
“We preach about not eating a lot of salt and sugar … for high blood
pressure and diabetes. But we don’t talk enough about prevention of
trauma,” she said.
