CCORT
  • CCORT is a group of over 30 outcomes researchers
    from 5 provinces (NS, QC, ON, AB, BC) who are
    working together on projects to measure and
    improve the quality of cardiac care in Canada
  • Funded by a CIHR Team Grant in Cardiovascular
    Outcomes Research
  • Institute for Clinical Evaluative Sciences (ICES)
    in Toronto is the national coordinating centre
    for CCORT
  • www.ccort.ca

Purpose of Study
  • To examine national trends between 1994 and 2005,
    in the prevalence of heart disease and
    cardiovascular disease risk factors
  • To see whether the rate of change of risk factors
    differs in Canadians of different age, sex and
    socioeconomic groups

Methods
  • We analyzed mortality data from Statistic
    Canadas National Population Health Surveys and
    the Canadian Community Health Surveys for the
    period 1994-2005
  • We determined age- and sex-standardized rates of
    heart disease and cardiovascular risk factors in
    those aged 12 years and over

category
8
Reasons for increasing trends
  • More patients with heart disease
  • Patients with heart disease are living longer
    because of better treatments
  • However, there will be a need for more cardiac
    care with the increasing number of individuals
    living with heart disease

Map of risk factors for cardiovascular disease in
Canada. Health regions are shown according to the
number of risk factors with a prevalence
exceeding the national average by at least 10.
Greater risk factor prevalence in
eastern provinces Fewer risk factors In
western provinces

Trends in diabetes from 1994 to 2005 stratified

17
Trends in obesity from 1994 to 2005 stratified by
age and sex
18
Reasons for increasing risk factors
  • Obesity
  • Physical inactivity and sedentary lifestyles
  • Environments not built to encourage exercise or
    walkability
  • Excessive caloric intake
  • Obesogenic diet High fat Little fresh fruits
    and vegetables
  • Diabetes
  • Increasing rates of obesity
  • Physical inactivity and sedentary lifestyles

19
Reasons for increasing risk factors
  • Hypertension
  • High rates of salt consumption
  • Obesity also increases hypertension risk
  • Better screening and detection of hypertension
  • Improved survival of patients with hypertension
    due to more and better medications

20
Trends in age- and sex-standardized rates of
hypertension from 1994 to 2005 by province
Hypertension is increasing in all provinces
21
Trends in age- and sex-standardized rates of
diabetes from 1994 to 2005 by province Diabetes
is increasing in all provinces
22
Trends in age- and sex-standardized rates of
diabetes from 1994 to 2005 by province Obesity
is increasing in many Canadian provinces
23
Conclusions
  • Key cardiovascular risk factors including
    hypertension, obesity, and diabetes are
    increasing fastest among younger Canadians (in
    their 50s or younger)
  • Hypertension and obesity are increasing in all
    socioeconomic groups
  • Diabetes is increasing in nearly all income
    groups, with the greatest increases in the
    poorest Canadians and the gap between the lowest
    and highest socioeconomic groups is widening
  • Heart disease is increasing in Canada with the
    prevalence increasing fastest in lower
    socioeconomic groups

24
Funding
  • This study was supported by a Team Grant in
    Cardiovascular Outcomes Research to the Canadian
    Cardiovascular Outcomes Research Team from the
    Canadian Institutes of Health Research
