Perinatal Conditions

Conditions which originate in the perinatal period, i.e. the period immediately before, during and after birth. This may include the following:

  • Fetus and newborn affected by maternal factors and by complications of pregnancy, labour and delivery
  • Disorders related to length of gestation and fetal growth
  • Birth trauma
  • Respiratory and cardiovascular disorders specific to the perinatal period
  • Infections specific to the perinatal period
  • Haemorrhagic and haematological disorders of fetus and newborn
  • Transitory endocrine and metabolic disorders specific to fetus and newborn
  • Digestive system disorders of fetus and newborn
  • Conditions involving the integument and temperature regulation of fetus and newborn

Population Centre

Population Centre has replaced the term urban area. It is an area with a population of at least 1,000 and a density of 400 or more people per square kilometre. All areas outside population centres continue to be defined as rural areas.

Small population centres have a population of between 1,000 and 29,999; medium population centres, 30,000 and 99,999; and large urban population centres, 100,000 and over.

Potential Years of Life Lost (PYLL)

The sum of the total years of life lost relative to age 75. PYLL is calculated by adding together, for all deaths, the number of years remaining until age 75, and then dividing by the population under the age of 75 years.

Pregnancy Rate

The number of in-hospital deliveries of live births and stillbirths, plus the number of therapeutic abortions, among females aged 15-49 years per 1,000 females aged 15-49.

Preterm Birth Rate

Number of live births delivered before 37 completed weeks of gestation per 100 live births.

Prevalence Rate

The total number of cases of an event in the population that exist for a certain period or point in time

Rate (Unadjusted or Crude)

Total number of events (e.g., deaths, births, hospitalizations) divided by the total population for a given time period and geography.

If one is interested in knowing the true event rates in a particular geographic area then unadjusted or crude rate should be used instead of age standardized rate.

Respiratory Diseases

‘Chronic respiratory diseases are chronic diseases of the airways and other parts of the lung. Some of the most common are asthma, chronic obstructive pulmonary disease (COPD), lung cancer, cystic fibrosis, sleep apnea and occupational lung diseases. Respiratory diseases affect all ages-children, teens, adults and seniors.’ Public Health Agency of Canada 2011 http://www.phac-aspc.gc.ca/cd-mc/crd-mrc/index-eng.php

Self-Reported Chronic Health Conditions Survey Question

The question in the Canadian Community Health Survey is “Now I’d like to ask about certain chronic health conditions which you may have. We are interested in ‘long-term conditions’ which are expected to last or have already lasted 6 months or more and that have been diagnosed by a health professional”.

Sex of person

Refers to the sex assigned at birth based on a person’s reproductive system and other physical characteristics. A person’s sex may differ from a person’s gender; a person’s gender may change over time and reflects the gender that a person internally feels and/or the gender a person publicly expresses.

Sex ratio at birth

The ratio of males born alive per 100 females born alive.

Small Counts

The stability of a rate is dependent on the number of events that contribute to that rate. Therefore, rates in small populations are often unstable due to the relatively small number of events that occur each year. When comparing trends over time between Middlesex-London, the province and the Peer Group, we often see a larger fluctuation in rates locally than for Ontario, in which the trends are fairly smooth from year to year – this concept needs to be considered when interpreting the time trends in this resource. Furthermore, the following strategies were implemented in order to present the most stable, reliable rates at the local level:

  • Rates based on counts less than 5 have been suppressed;  
  • Directly age-standardized rates have only been derived where there were 20 or more events across all age groups;
  • For most unadjusted rates and rates of rare outcomes, multiple years of data have been collapsed to present an average annual rate. 

Small-for-Gestational Age Rate

The number of live births with a birth weight below the tenth percentile of birth weights for their gestational age and sex, per 100 live births.

Smog

Smog is made up of predominantly ground-level ozone and fine particulate matter. Ozone has an impact on smog levels primarily in summer whereas fine particulate matter elevates smog levels all year. http://airqualityontario.com/press/faq.php

Smoke Free Ontario Act

The Smoke-Free Ontario Act is legislation enacted in 2006 that bans smoking from enclosed workplaces and public places in Ontario. In 2009, smokers were banned from smoking in cars with children under the age of 16 (Ontario Ministry of Health Promotion, 2010).

Standard Drink Size

A standard drink is 13.6 g of alcohol, which translates into 5 oz of wine, 1.5 oz of spirits, or 12 oz of regular strength 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.
