Special Air Quality Statement (SAQS)

A Special Air Quality Statement (SAQS) is issued when a high or very high risk AQHI rating is expected for one to two hours on a given day.

Standard Drink Size

A standard drink is 13.6 g of alcohol, which translates into 5 oz of 12% wine, 1.5 oz of 40% distilled alcohol (rye, gin, rum, etc.), or 12 oz of 5% beer.

Standardized Hospitalization Ratio (SHR)

Actual number of hospitalizations in the Middlesex-London population divided by the number of hospitalizations expected if the population had the same age and sex specific rates as the population of Ontario.

Standardized Hospitalization Ratio Interpretation (SHR)

  • An SHR of 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, the hospitalization rate in Middlesex-London is the same as the rate for Ontario.
  • An SHR of greater than 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, there is a higher hospitalization rate in Middlesex-London than in Ontario.
  • An SHR of less than 1 indicates that, after adjusting for the effect of differences in age or sex structure between the geographic areas, there is a lower hospitalization rate in Middlesex-London than in Ontario.
  • The vertical black line above and below the dot indicates the upper and lower confidence intervals. When the confidence interval does not cross 1, the difference between the rate for Middlesex-London and Ontario is statistically significant.

Standardized Mortality Ratio (SMR)

Actual number of deaths in the Middlesex-London population divided by the number of deaths expected if the population had the same age and sex specific mortality rates as the population of Ontario.

Standardized Mortality Ratio (SMR) Interpretation

  • An SMR of 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, the mortality rate in Middlesex-London is the same as the rate for Ontario.
  • An SMR of greater than 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, there is a higher mortality rate in Middlesex-London than in Ontario.
  • An SMR of less than 1 indicates that, after adjusting for the effect of differences in age or sex structure between the geographic areas, there is a lower mortality rate in Middlesex-London than in Ontario.
  • The vertical black line above and below the dot indicates the upper and lower confidence intervals. When the confidence interval does not cross 1, the difference between the rate for Middlesex-London and Ontario is statistically significant.

Statistical Significance

A difference between two estimates which is statistically significant indicates that it is very unlikely to have occurred due to chance alone.

Stillbirth rate

The number of births that are stillborn per 1,000 births (live or still).

Stress

Can be normal in response to certain pressures and demands that occur in everyday life. Chronic stress can lead to poor health including mental health problems and medical issues.1

Struck by or against

This category of injuries includes being struck by a falling object, such as a rock. Sport equipment such as a ball or hockey stick are also included as well as situations where people run into other objects such as a wall. It does not include assault, intentional self-harm, collisions with other people or being struck by a car as a pedestrian. 

Sulphur Dioxide

Sulphur Dioxide (SO2) is a gaseous oxide that results from the combustion of sulphur containing fossil fuels and also from the smelting of sulphur containing ores. Typically SO2 is emitted from electrical utilities and other industrial facilities. Sulphur dioxide is also a precursor to sulphate aerosols, commonly contained within fine and ultrafine particulate matter, and to the formation of acid rain.

Syphilis categories

A syphilis infection is categorized as primary, secondary, early latent, late latent or tertiary depending on the amount of time since the initial infection and the presenting symptoms.  During the primary, secondary and early latent stages, syphilis infections can be spread to others.  Late latent and tertiary infections cannot spread to others but may lead to significant health problems for the infected individual.
