“…Our findings suggest that the rise in hypertension prevalence reported in our other study 8 was because of an increase in incidence and a decline in mortality. It is also possible that physicians are improving their detection of hypertension and are detecting it earlier, thereby also contributing to the increasing prevalence.…”

Background:We have reported that the prevalence of diagnosed hypertension increased by 60% from 1995 to 2005 in Ontario. In the present study, we asked whether this increase is explained by a decrease in the mortality rate. Methods:We performed a population-based cohort study using linked administrative data for Ontario, a Canadian province with over 12 million residents. We identified prevalent cases of hypertension using a validated case-definition algorithm for hypertension, and we examined trends in mortality from 1995 to 2005 among adults aged 20 years and older with hypertension. Results:The age-and sex-adjusted mortality among patients with hypertension decreased from 11.3 per 1000 people in 1995 to 9.6 per 1000 in 2005 (p < 0.001), which is a relative reduction of 15.5%. We found that the relative decrease in age-adjusted mortality was higher among men than among women (-22.2% v. -7.3%, p < 0.001). Interpretation:Mortality rates among patients with hypertension have decreased. Along with an increasing incidence, decreased mortality rates may contribute to the increased prevalence of diagnosed hypertension. Sex-related discrepancies in the reduction of mortality warrant further investigation. AbstractFrom the Institute for Clinical Evaluative Sciences (Tu, Chen, Lipscombe); and the

“…However, the rising prevalence of overweight/ obesity among adults and youth and hypertension and diabetes among adults are cause for concern. Canadian population-based studies using other data sources have found similar increases in the prevalence of obesity, 11 hypertension 12 and diabetes. 13 The trends in risk factors and associated CANHEART health index scores should be closely monitored over time because these factors are associated with the development of many chronic diseases.…”

C ardiovascular disease, which includes heart disease and stroke, is the second leading cause of death in Canada and is associated with disability, low quality of life and high economic costs.1 Although much previous research has focused on the contribution of individual health behaviours and factors to the risk of cardiovascular disease, there has been little focus on comprehensively examining the cardiovascular health of the population.In 2010, the American Heart Association introduced a definition of ideal cardiovascular health based on 7 health factors and behaviours (smoking, body mass index [BMI], diet, physical activity, and blood pressure, glucose and cholesterol levels).2 Criteria were established to define ideal levels of each health factor or behaviour. The American Heart Association set a goal of improving the cardiovascular health of Americans by 20% by 2020. Studies have shown that meeting 6-7 metrics of ideal cardiovascular health is associated with an 89% lower incidence of cardiovascular disease, 3 76% reduction in stroke incidence, 4 70% reduction in ischemic heart disease mortality 5 and 51% lower incidence of cancer 6 compared with meeting 0 or 1 of the ideal metrics.

“…Our contrasting results may be due, in part, to the greater screening for conditions such as hypertension and diabetes in a setting with universal access to health care. 24,25 Increasing prevalence of cardiovascular disease and its pre- disposing risk factors may be due to rising incidence, enhanced identification 26 or increased survivorship among those with prior myocardial infarction or coronary disease. [27][28][29] The increase in obesity is likely multifactorial and may be due to decreasing physical activity, sedentary lifestyle, obesogenic dietary pattern and sex-related effects (since the rise in obesity was less for women than for men).…”
