Unintentional
Injuries - Injury Prevention
Data
definitions, limitations & uses • Data Sources
Unintentional
injuries are an important priority for public
health due to the fact that it has been estimated
that 90% of all injuries are preventable. In
addition, a recent report published in conjunction
with SMARTRISK, Health Canada, Ontario Unintentional
injuries are an important priority for public
health due to the fact that it has been estimated
that 90% of all injuries are preventable. In
addition, a recent report published by the
following partners: SMARTRISK; Health Canada;
Ontario’s Ministry of Health and Long Term Care;
and the Kingston, Frontenac, Lennox and Addington
Public Health Unit, found that more than 2 million
Canadians are injured every year at an annual cost
of more than $8.7 billion.
In Leeds, Grenville and Lanark (LGL),
in1996 injuries were the fourth leading cause of
death and the third leading cause of potential
years of life lost (PYLL). Overall, in 1996, there
were 72 injury deaths per 100,000 men and 52
injury deaths per 100,000 women.
Motor
Vehicle Collisions
Between 1992 and 1996, motor vehicle collisions (MVCs)
accounted for about 2% of all deaths in Leeds,
Grenville and Lanark (LGL). In this same period
MVCs were the cause of approximately 19 deaths and
70 hospitalizations per year (see figure 1).
The crude mortality rate was 14 deaths per 100,000
people . This rate was twice as high in men than
in women (see
figure 2)
However, this difference is much smaller
than it was in the early 1980's, when the
mortality rate was three times as high in men than
women.
Compared to Ontario, mortality due to MVCs was
significantly higher in residents in LGL than the
rest of the province (see figure 3). Hospitalizations
rates due to MVCs for men (see figure 4) and
women (see figure 5)
in LGL were very similar to rates in Ontario.

Falls (Falls)
Between 1997 and 1998, there were 109,976 injury
admissions due to unintentional falls (falls) in
Canada. These accounted for 54% of all injury
admissions in Canada. In this same period,
injuries due to falls were also the leading cause
of hospital deaths (76%) and days in hospital due
to injury (68%). The mean length of stay in
hospital for falls was 12 days. Females accounted
for 58% of injury admissions. Over half (57%) of
injury admissions due to falls occurred in persons
65 years of age and older.
Between 1993 and 1997 there were 3539 (708/per
year) hospitalizations due to falls in Leeds,
Grenville and Lanark (LGL) (see figure 6). Of
these, 63% occurred among women. Falls have been
found to be strongly related to age. However, the
relationship is not linear, as rates are high in
children under 15, remain low among 15-29 year
olds, then begin to rise exponentially . Among all
fall related hospitalizations observed between
1993 and 1997, 66% occurred among senior residents
(65 and older). Age
specific hospitalizations rates among seniors are
more than twice as high as in the population as a
whole (see figure 7).
When
compared to Ontario, hospitalizations due to falls
among residents in LGL are similar for both men (see figure 9) and
women (see figure
10).
In addition to being a leading cause of
hospitalizations in the region, falls account for
a large proportion of the deaths observed in LGL.
Between 1994 and 1996 falls accounted for 3% of
all deaths in Leeds, Grenville and Lanark. This
translates into 12.4 deaths per 100,000 males and
24 deaths per 100,000 females (see figure 8).
Falls also make up a large proportion of all
injury deaths among residents in LGL. Between
1994-1996, falls accounted for 53% of all injury
deaths among women and 20% among men. Compared to
Ontario, deaths due to falls were greater in LGL
for women, but not men (see figure 11).
Looking at fall data over time illustrates
that falls are a leading cause of injury in LGL,
accounting for a large number of deaths and
potential days spent in hospital. This data also
points out that the majority of injuries due to
falls occur in older adulthood, where a
disproportionate number of falls are suffered by
older women.

Suicide
Suicide is a significant preventable cause of
death and potential years of life lost (PYLL),
especially among young people. Suicide is an
indicator of mental health. There are many factors
thought to contribute to suicides, among which are
recent mental disorders and substance abuse. This
indicator shows only the final consequences of the
suicide phenomenon, since the lives lost represent
only a proportion of all attempted suicides.
In Leeds, Grenville and Lanark (LGL) there were
278 suicide deaths between 1981 and 1996. The
total suicide mortality rates haven't changed much
over the past 15 years. Between 1981 and 1986, the
suicide mortality rate was 13 deaths per 100,000
people, roughly the same as the rate in 1992 to
1996 (12 deaths per 100,000 people).
The sex differences in suicide rates are dramatic.
Despite the fact that women were twice as likely
as men to be depressed (see figure 12) (in
the combined regions of Leeds, Grenville and
Lanark, Kingston, Frontenac, Lennox and Addington
and Hastings and Prince Edward), suicide rates
are, and have been much higher in men and than in
women (see figure
13). Of the 278 suicides in LGL, between 1981
and 1996, 80% were committed by men. In
the past few years the suicides rates in LGL have
been about the same as in all of Ontario. Between 1994 and
1996, the age-standardized suicide rate in LGL was
11.7 deaths per 100,000 people, about the same as
in Ontario, where the rate was 9.7 deaths per
100,000 people (see
figure14).
