Hypertension
Hypertension is a chronic condition of consistently high blood pressure over a long period of time. Blood pressure is the force of blood inside the walls of blood vessels. High blood pressure (Heart & Stroke Foundation) is usually defined as a systolic blood pressure (top number) at 140 mmHg or higher and/or a diastolic blood pressure (bottom number) at 90 mmHg or higher.
Hypertension by geographic area
Key findings:
- In 2013/14, survey results indicated that prevalence rate of hypertension was 20% in the Sudbury & District Health Unit (SDHU) area.
- The prevalence rate of hypertension in the SDHU area has consistently been similar to that reported in northeastern Ontario, and in Ontario overall.
- Between 2005 and 2013/14, the rate of hypertension in the SDHU area has not varied significantly.
Notes:
- Rates are age-standardized using the 2006 Canadian population.
- Rates are for the population aged 12 years and older.
- Data Source: Canadian Community Health Survey, Ontario Share Files, Statistics Canada.

| Ontario | Percentage (%) | 17.2 | 17.9 | 18.0 | 17.7 | 18.2 |

Hypertension by sex
Key findings:
- In 2013/14, survey results indicated that prevalence rate of hypertension was 22% in males, and 17% in females, in the SDHU area.
- The prevalence rate of hypertension in the SDHU area males has consistently been higher than in SDHU-area females.
- Between 2005 and 2013/14, the rate of hypertension in the SDHU area has not varied significantly in either males or females.
Notes:
- Rates are age-standardized using the 2006 Canadian population.
- Rates are for the population aged 12 years and older.

| Females | Percentage (%) | 16.5 | 18.8 | 18.6 | 17.1 | 17.1 |
| Females | 95% Confidence Interval | 14.2 to 19.2 | 16.1 to 21.9 | 14.9 to 22.9 | 13.9 to 20.8 | 13.8 to 21.0 |
Hypertension by age group
Key findings:
- In 2013/14, survey results indicated that the prevalence rate of hypertension was 56% in adults aged 65 years and over in the SDHU area. This is much higher than the rate in younger age groups.
- Reported rates of hypertension varied from year to year between 2005 and 2013/14, but these differences are within the margin of error of the survey. Thus, there is no clear trend in the prevalence rate of hypertension within each age group.
Notes:
- Rates are for the population aged 12 years and older.
