Health status assessment and disease surveillance are essential to ide
ntify and priorize health issues, to evaluate intervention programs an
d to plan to meet future needs for health services. Canadians currentl
y benefit by having among the highest life expectancies at birth in th
e world (81 for females, 74 for males). Disability-free life expectanc
ies for females and males, respectively, were 10.1 and 11.3 years lowe
r for the lowest income quintile compared to the highest. Canada's inf
ant mortality rate in 1990 (7/1000 live births) was one of the lowest
in the world but within Canada, the rate in the lowest income quintile
(10.5/1000 live births) was almost double that in the highest income
quintile (5.8/1000 live births). Fair or poor health was reported by 3
6% of adult Canadians in the lowest income category in 1990 compared t
o only 5% in the highest income group. The leading causes of premature
death for females in 1991 were breast cancer, coronary heart disease,
lung cancer, car crashes, birth defects and suicide; those for males
were coronary heart disease, suicide, car crashes, lung cancer, birth
defects, and AIDS. Lowest income quintile males had mortality rates at
least double those for the highest income quintile for alcohol-relate
d conditions, violence, injuries and emphysema. Cardiovascular disease
s, cancer, musculoskeletal diseases, injuries and respiratory diseases
imposed the highest direct and indirect economic costs in Canada in 1
986. For all of these conditions, improved prevention is possible. For
example, the forecasted tobacco-related deaths before age 70 among cu
rrent male smokers age 15 will far exceed those due to car crashes, su
icide, murder, AIDS, and drug abuse combined. Population aging will ag
gravate trends for many chronic conditions especially those with incre
asing incidence rates; there will be large increases in the numbers of
persons with aging-related cancers, dementias and other conditions. T
here is an urgent need for Canadian health jurisdictions to ensure tha
t rational priorities, goals/objectives, strategies, and programs are
in place to enhance prevention and disease control.
