A

Aboriginal Identity

Includes persons who reported being an Aboriginal person, that is, First Nations (North American Indian), Métis or Inuk (Inuit) and/or those who reported Registered or Treaty Indian status, that is registered under the Indian Act of Canada, and/or those who reported membership in a First Nation or Indian band. Aboriginal peoples of Canada are defined in the Constitution Act, 1982, section 35 (2) as including the Indian, Inuit and Métis peoples of Canada. 

Active Transportation

Active transportation refers to any method of travel that is human-powered, but is usually associated with walking and bicycling.

Actual Incidents

When a crime is reported to the police, the incident is recorded as a "reported" incident. Police then conduct a preliminary investigation to determine the validity of the report. Occasionally, crimes reported to the police prove to be unfounded. Unfounded incidents are subtracted from the number of reported incidents to produce the number of "actual incidents." Numbers and rates of crime are calculated on the basis of "actual incidents" categorized according to the most serious offence.

Acute Flaccid Paralysis (AFP)

Paralysis is a loss of muscle function to one or more muscle groups. Flaccid paralysis is paralysis with reduced muscle tone. Acute flaccid paralysis is the sudden onset of flaccid paralysis that can not be explained by any other cause (e.g. trauma).

Adequate Housing

Adequate housing does not require any major repairs, according to residents. Major repairs include defective plumbing or electrical wiring, or structural repairs to walls, floors or ceilings.

Affordable Housing

Affordable housing costs less than 30% of before-tax household income.

For renters, shelter costs include, as applicable, rent and payments for electricity, fuel, water and other municipal services.

For owners, shelter costs include, as applicable, mortgage payments (principal and interest), property taxes, condominium fees, and payments for electricity, fuel, water and other municipal services.

After Tax Income

Total income minus federal, provincial and territorial income taxes paid for calendar year 2010.

Age Distribution

The frequency (number of people) of each age or age group in a population.     

Age-Specific Rate

The number of events (e.g. cases of disease, deaths) in a particular age group in a particular region, divided by the number of persons in that age group in that region. The rate is usually reported per 100,000 population. The numerator and denominator refer to the same age group.  

Age Standardized Incidence Rate

The incidence rate that a population would have if it had the same age distribution as a reference population. Age standardization is used to compare incidence rates of disease between populations with different age distributions. For example, some sexually transmitted infections (STI's) are more common among 15-24 year olds so a population with a higher proportion of this age group will have a higher overall incidence rate of STI's. In order to determine which population has a higher incidence rate regardless of age distribution, the rates must be age standardized. Most HealthSTATS pages will use the 2011 Canadian Standard population but older pages may still use the 1991 Canadian Standard population. Details for which reference population was used will be included on the page.

Age Standardized Emergency Visit Rate

Age standardized emergency visit rate is defined as the number of emergency visits, as recorded in the National Ambulatory Care Reporting System (NACRS), due to a specific cause per 100,000 population that would occur if the population had the same age distribution as a reference population. Age-standardization allows for comparisons of mortality rates between populations with different age distributions. Most HealthSTATS pages will use the 2011 Canadian Standard population but older pages may still use the 1991 Canadian Standard population. Details for which reference population was used will be included on the page.

Age Standardized Hospitalization Rate

Age standardized hospitalization rate is defined as the number of hospital discharges, as recorded in the

Discharge Abstract Database

(DAD), due to a specific cause per 100,000 population that would occur if the population had the same age distribution as a reference population. Age-standardization allows for comparisons of mortality rates between populations with different age distributions. 

 

The Association of Public Health Epidemiologists in Ontario (APHEO) recommend counting injury-related hospitalizations from National Ambulatory Care Reporting System (NACRS) instead of DAD. Therefore, injury-related hospitalization data on HealthSTATS reports hospital admissions through the emergency department.   

Age Standardized Mortality Rate

Age standardized mortlity rate is defined as the number of deaths due to a specific cause per 100,000 population that would occur if the popluation had the same age distribution as the 1991 Canadian population. Age-standardization allows for comparisons of mortality rates between populations with different age distributions. Most HealthSTATS pages will use the 2011 Canadian Standard population but older pages may still use the 1991 Canadian Standard population. Details for which reference population was used will be included on the page.

Alcohol Attributable Deaths

The number of deaths attributable to alcohol consumption. Alcohol-attributable deaths are those deaths that would not have happened without the presence of alcohol.

Anaphylaxis

A severe, whole-body allergic reaction that happens quickly after the exposure.

Antibodies

Proteins released by immune cells to fight against micro-organisms (ex. viruses, bacteria etc.) that invade the body.

Asthma

Asthma, from the Greek for panting, is a chronic inflammatory disease of the airways. This inflammation may cause the airways to narrow when exposed to certain triggers, resulting in wheezing and breathlessness. Triggers for asthma symptoms can vary from one person to another and include both allergic triggers (e.g. dust, pollen, mould, etc.) and non-allergic triggers (e.g. exercise, cold air, air pollution, etc.).
ICD 10 Codes: J45-J46

It extends up to the collarbone and from the armpit across to the breastbone in the centre of the chest. Cancer cells may start within the ducts (this is called ductal carcinoma) or in the lobules (lobular carcinoma). Ductal carcinoma is the most common type of breast cancer.
ICD 10 Codes: C50

Cancer of Colon, Rectum & Anus

Often call colorectal cancer, these include all malignant neoplasms (tumours) of the large intestine and anus. Most colorectal cancers start in the cells that line the inside of the colon or the rectum. Colorectal cancer usually grows slowly and in a predictable way. It is curable when diagnosed at an early stage.
ICD 10 Codes: C18-C21, C26.0

Cancer of Lung & Bronchitus

Includes all malignant neoplasms (tumours) of the bronchus and lung. Virtually all lung cancers arise in epithelial tissue, and most originate from the lining of the bronchi.
ICD 10 Codes: C34

Cancer of Lymph, Blood & Related

Include a wide variety of cancers originating in bone marrow, lymphatic tissue or other blood related cells. The most common types of cancers included in this grouping are: leukemia, Hodgkin’s and Non-Hodgkin’s lymphoma and multiple myeloma.

Census

The census collects information on every man, woman and child in Canada. It provides a statistical portrait of Canada and its people. A census is conducted once every five years in this country. The most recent census was on May 16, 2006.

Data are collected through a questionnaire that is filled out by an adult in each household and mailed back to Statistics Canada. Not all respondents receive the same questionnaire. Four out of five households receive a short form while the remaining one in five receives a long form. The short form contains seven questions: the respondent’s name, sex, age, marital and common-law status, family and household relationships and mother tongue. The long form includes the seven questions from the short questionnaire plus 52 additional questions, including a question on religion and new questions on birthplace of parents and language spoken at work.

This method of gathering detailed data from a sample of households was first employed in the 1941 Census of Canada. Sampling is an effective collection method, yielding high-quality data while reducing costs. 

Census Division

A census division is a group of neighbouring municipalities joined together for the purposes of regional planning and managing common services.  For our purposes, Simcoe County and Muskoka District are census divisions.

Census Family

This definition of the census family classifies people in the following manner: 1) couples (married or common-law) living in the same dwelling, with or without children; and 2) lone-parents (male or female) with one or more children. The residual population is called "persons not in census families" or “non-family persons” and is made up of persons living alone and of persons living in a household, but who are not part of a couple family or lone-parent family.

Census Metropolitan Area (CMA) and Census Agglomeration (CA)

Statistics Canada defines these as areas consisting of one or more neighbouring municipalities situated around a core. A census metropolitan area must have a total population of at least 100,000 of which 50,000 or more live in the core. A census agglomeration must have a core population of at least 10,000.

Cerebral Palsy

ICD 10 Codes: I60-I69

Chancre

A primary sore or ulcer at the site of entry of a pathogen.

Childhood Overweight

Body mass index (BMI) is typically used to measure overweight in children. BMI is calculated by dividing the child’s weight in kilograms by their height in metres squared. There are two different ways to determine if a child is overweight based on their measured BMI: the CDC growth charts to determine the corresponding BMI-for-age percentile OR the International Obesity Taskforce (IOTF) recommended BMI cut-off points.

Using the CDC growth chart method, the child’s BMI is plotted on the CDC BMI-for-age growth charts (for either girls or boys) to obtain a percentile ranking. The percentile indicates the relative position of the child’s BMI among children of the same sex and age. Overweight is defined as a BMI at or above the 95th percentile for children of the same age and sex. Those with BMI from the 85th to less than the 95th percentile are considered at risk of overweight.

The recommended IOTF BMI cut-off points were developed by researcher Tim Cole and others. They are based on pooled international data (Brazil, Great Britain, Hong Kong, Netherlands, Singapore and United States) for BMI and linked to the internationally accepted adult BMI cut-off points of 25 (overweight) and 30 (obese).

Chronic Lower Rispiratory Diseases

Chronic respiratory diseases are persistent conditions affecting the airways and other structures of the lung. Common conditions include: asthma, chronic obstructive pulmonary disease (COPD) and respiratory allergies.
ICD 10 Codes: J40-J47

Chronic Obstructive Pulmonary Disease (COPD)

Chronic obstructive pulmonary disease (COPD) is a group of diseases characterized by airflow obstruction that can be associated with breathing-related symptoms like chronic coughing, expectoration and wheezing. The obstruction is generally permanent and becomes worse over time. The most significant risk factor for COPD is long-term cigarette smoking.

Median commuting duration is the value which divides the commuting duration into two equal halves, i.e., the commuting duration of individuals for the first half is below the median, while the commuting distance of individuals for the second half is above the median.

Confidence Interval

The 95% confidence interval indicates the interval or range within which the true population percentage probably lies. The reason for using confidence intervals is due to the uncertainty, or sampling error, associated with using results obtained from a sample to draw conclusions about the entire population from which the sample was drawn. The confidence interval (in our case, a 95% confidence interval) can also be interpreted as being 95% likely to include the percentage value we would have obtained if we had studied every member of the target population.

As the coronary arteries narrow, the flow of blood to the heart can slow or stop, causing chest pain, shortness of breath, heart attack, or other symptoms.

Couple Family

Includes families that contain a married or common-law couple (either with or without children). A couple may be of opposite or same sex.

Diabetes mellitus (DM) is a chronic condition that results from the body's inability to sufficiently produce and/or properly use insulin. Insulin is the hormone responsible for controlling the levels of glucose (sugar) in the blood. Consistent high levels of blood glucose can result in long-term damage, leading to the dysfunction and failure of various organs, such as the kidneys, eyes, nerves, heart and blood vessels.
ICD 10 Codes: E10-E14

Income Quintile

An income quintile divides the population into five equally sized income groups (from lowest income to highest income) such that 20% of the population (or households) are in each group. For the survey data (like CCHS), income is reported at an individual level and an income quintile is assigned to the respondent based on this self-reported household income. For administrative data (like deaths and hospitalizations) individual level income is not known, so income quintiles are approximated based on where the individual lives (sometimes known as neighbourhood income quintiles).

Infectious Agent

An organism (agent) capable of causing infection such as bacteria, viruses or parasites.

Influenza and Pneumonia

Influenza is a viral infection that may cause pneumonia and death among elderly persons and those with cardiovascular or pulmonary disease conditions. Influenza and pneumonia are usually combined together because the confirmation of influenza as the causative agent can be difficult and under-represents the true number of cases.
ICD 10 Codes: J10-J18

International Classification of Diseases and Related Health Problems 10th Revision (ICD-10)

The international classification of diseases and related health problems (ICD) sets the standard for diagnostic classification for the compilation of national mortality and morbidity statistics by WHO Member States, including Canada. The ICD has undergone several periodic revisions over the years, which have been coordinated by the World Health Organization (WHO) since 1948. The ICD is currently in it's tenth revision (ICD-10). The most current version of the ICD-10 is available on the WHO website -http://apps.who.int/classifications/apps/icd/icd10online/.

The ICD-10 has undergone some modification to meet the specific administrative, epidemiological and public health research requirements of Canadians (ICD-10-CA). ICD-10-CA was developed by the Canadian Institute for Health Information (CIHI) in collaboration with an Expert Panel of physicians, external field reviewers and the CIHI classification team. The ICD-10-CA is based on and is wholly comparable with WHO ICD-10 classification. The ICD-10-CA is the classification recommended in most clinical settings. It is the national standard for reporting morbidity statistics.

Invasive

Latent Tuberculosis Infection (Latent TB)

People with latent TB infection have TB bacteria in their bodies, but the bacteria are not active so these people are not sick. This is different than TB disease where the bacteria are multiplying and damaging tissue. People with latent TB infection do not have symptoms of TB disease and they cannot spread the germs to others. However, they may develop TB disease in the future. They are often prescribed medicine to prevent them from developing TB disease. This medicine must be taken for several months.

Lesion

Long-Term Unemployed

The long term unemployed includes unemployed persons in private households who last worked in or before 2010.

Lorenz Curve

The Lorenz Curve is often associated with income distribution calculations by helping us to visualize the distribution of wealth in a population. For example, if income distribution were perfectly equal, 30% of households would bring in 30% of a population’s income.

Low Birth Weight

An infant weighing less than 5lbs 8oz or 2500 grams at birth regardless of gestational age.

Low Income Cut-off (LICO)

Income levels at which families or unattached individuals spend 20% more than average on food, shelter and clothing. The low income cut-offs (LICOs) represent levels of income where people spend disproportionate amounts of money for food, shelter, and clothing. LICOs are based on family and community size. The cut-offs are regularly updated to account for changes in the consumer price index.

Low Income Measure

Statistics Canada defines this as a fixed percentage (50%) of median adjusted household income, where “adjusted” reflects the fact that as the number of household members increases, a household’s needs also increase. A family is considered to be low income when their income is below the Low-Income Measure (LIM) for their family type and size.

Low Lying Placenta

A complication of pregnancy (also known as placenta previa) when the placenta is in the lower segment of the uterus and covers part or all of the cervix blocking the baby's way out of the uterus.

M

Macrocephaly

Macrocephaly is defined as a head circumference more than two standard deviations larger than the average for a given age and sex. Generally, this is used to refer to a congenital anomaly observed among newborns.

Market Basket Measure (MBM)

Market Basket Measure is based on the cost of a specific basket of goods and services representing a modest, basic standard of living. It includes the costs of food, clothing, footwear, transportation, shelter and other expenses for a reference family of two adults aged 25-49 and two children (aged 9 and 13).

MET

The metabolic equivalent or MET is a way to measure the intensity of physical activity. One MET is the amount of energy (oxygen) used by the body at rest (i.e. the resting metabolic rate). The harder your body works during a physical activity, the higher the MET. MET-minutes can be calculated by multiplying the MET score of an activity by the number of minutes the activity is performed for. MET-minute scores are equivalent to kilocalories for a 60 kilogram person.

Microorganism

An organism of microscopic or submicroscopic size.

Minimum Wage

The lowest hourly wage rate that an employer can legally pay its employees.

Mother Tongue

The first language learned at home in childhood and still understood by the person at the time the data was collected. If the person no longer understands the first language learned, the mother tongue is the second language learned. For a person who learned two languages at the same time in early childhood, the mother tongue is the language this person spoke most often at home before starting school. A person has two mother tongues only if the two languages were used equally often and are still understood by the person.

Abnormalities in the development of the spinal cord, skull and brain, resulting from failure of the neural tube to close properly during fetal development.

Nitrogen Dioxide

Nitrogen dioxide (NO2) is typically the indicator gas measured to indicate concentrations of nitrogen oxides (NOx) in the air.  NO2 in particular, and NOx in general are produced by high-temperature combustion which occurs in vehicle engines, industrial processes and power generation. NO2 contributes to the formation of ozone in the atmosphere. Inhalation of NO2 has been linked to acute and chronic respiratory disease and increased susceptibility to inhaled allergens.

Opioid Poisoning

​Opioid poisoning include all emergency visit or hospital discharge where there was an overdose or the substance was given or taken in error. The ICD-10-CA codes were limited to following relevant opioid poisonings:

• T40.0 (poisoning by opium)

• T40.1 (poisoning by heroin)

• T40.2 (poisoning by other opioids)

• T40.3 (poisoning by methadone)

• T40.4 (poisoning by synthetic opioids)

• T40.6 (poisoning by unspecified/other opioids).

Since these ICD-10-CA codes group opioids into broad categories, it is not possible to attribute emergency visits or hospitalizations to a specific opioid, such as fentanyl or oxycodone. Included were all emergency visits or hospitalizations where any diagnosis for opioid poisoning was used, excluding suspect or query diagnoses.

Physical Activity

International Physical Activity Questionnaire (IPAQ)
The IPAQ assesses physical activities across four domains (leisure time, domestic & yard work, work related physical activity and transport related physical activity). The total amount of physical activity is quantified and categorized into the following three levels:

High
The two criteria for classification as ‘high’ are:
a) vigorous-intensity activity on at least 3 days achieving a minimum total
physical activity of at least 1500 MET-minutes/week
OR
b) 7 or more days of any combination of walking, moderate-intensity or
vigorous-intensity activities achieving a minimum total physical activity
of at least 3000 MET-minutes/week.

Moderate
The pattern of activity to be classified as ‘moderate’ is either of the following criteria:
a) 3 or more days of vigorous-intensity activity of at least 20 minutes per day
OR
b) 5 or more days of moderate-intensity activity and/or walking of at least 30
minutes per day
OR
c) 5 or more days of any combination of walking, moderate-intensity or vigorous
intensity activities achieving a minimum total physical activity of at least 600
MET-minutes/week.

Low
This is the lowest level of physical activity. Those individuals who not meet criteria for Categories 2 or 3 are considered to have a ‘low’ physical activity level.

Statistics Canada's Leisure Time Physical Activity Index
Self-reported level of physical activity, based on their responses to questions about the nature, frequency and duration of their participation in leisure-time physical activity over the past 3 months.

Respondents are classified as active, moderately active or inactive based on an index of average daily physical activity during their leisure time. An average daily energy expenditure is calculated by multiplying the number of times the activity was performed by the average duration of the activity by the energy cost (kilocalories per kilogram of body weight per hour) of the activity. The index is calculated as the sum of the average daily energy expenditures of all activities.

Respondents are classified as follows:

Physically active: 3.0 kcal/kg/day or more

Moderately active: 1.5 to 2.9 kcal/kg/day

Inactive: less than 1.5 kcal/kg/day

SHAPES Physical Activity Levels

The following physical activity levels were based on responses to past seven day frequency and duration of hard and moderate physical activity. The cut-offs for the selected levels were chosen to be to be consistent with Canadian Fitness and Lifestyle Research Institute (CFLRI).

Active
Has expended an average of 8 or more kilocalories per kilogram of body weight per day or greater during physical activity in the 7 days preceding the survey.

Moderately Active
Has expended an average of 3 to 8 kilocalories per kilogram of body weight per day during physical activity in the 7 days preceding the survey.

Inactive
Has expended an average of less than 3 kilocalories per kilogram of body weight per day during physical activity in the 7 days preceding the survey.

Physically Active

Enough metabolic energy has been expended during leisure time over the past three months to give some cardiovascular benefit.

Placenta Previa

A rare condition during pregnancy when the placenta attaches at the bottom of the uterus (rather than the top), blocking the opening to the vaginal canal and interfering with delivery of the baby.

Placental Abruption

A rare and serious condition during pregnancy when the placenta separates from the uterus before the baby is born.

Pneumonia

Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus.

Population Estimates – Intercensal

Intercensal estimates are produced using counts from two consecutive censuses adjusted for census net undercoverage (CNU) (including adjustment for incompletely enumerated Indian reserves) and postcensal estimates. The production of intercensal estimates involves updating the postcensal estimates using the counts from a new census adjusted for CNU.

Population Estimates – Postcensal

Postcensal estimates are produced using data from the most recent census adjusted for CNU and the components of population growth. In terms of timeliness, postcensal estimates are more up-to-date than data from the most recent census adjusted for CNU, but as they get farther from the date of that census, they become more variable.

Population Pyramid

The most important demographic characteristic of a population is its age-sex structure. Age-sex pyramids (also known as population pyramids) graphically display this information to improve understanding and ease comparison.

Age-sex pyramids display the percentage or actual amount of a population broken down by gender and age. The five-year age increments on the y-axis (vertical axis) allow the pyramid to reflect long term trends in the birth and death rates but also reflect shorter term baby-booms, wars and epidemics.

Potential years of life lost (PYLL) is the number of years of potential life not lived when a person dies "prematurely", defined for this indicator as before age 75. PYLL can be calculated for all causes of death or for specific causes. All PYLL statistics use the population aged 0 to 74. PYLL is often reported as an age-standardized rate per 1,000 persons age 0 to 74. 

Preeclampsia

Problem Video Gaming

The 2015 Ontario Student Drug Use and Health Survey (OSDUHS) used a nine question scale to assess problem video gaming among students. To be considered having problem video gaming, students needed to report at least 5 of 9 symptoms on the Problem Video Game Playing (PVP) screening tool, which measured preoccupation, tolerance, school and family problems due to video game playing in the past 12 months.

Protozoa

Any of a large group of single-celled, usually microscopic organisms, such as amoebas, ciliates and flagellates. Some can cause disease in humans.

Psychological Distress

The 2015 Ontario Student Drug Use and Health Survey (OSDUHS) used the Kessler 6-Item Psychological Distress Scale (K-6; Kessler et al., 2003) was used to measure non-specific psychological distress (symptoms of anxiety and/or depression) occurring in the past four-weeks. A score of 13 or higher on the six questions was used to indicate serious psychological distress and a score between eight and 12 was used to indicate moderate distress.

Q

Quintile of Annual Income Per Person Equivalent (QAIPPE)

Statistics Canada calculates the average income per person by dissemination area (DA). Twenty-percent of DAs with the lowest incomes have a QAIPPE of ‘1’. This continues up the scale with 20% of DAs with the next highest incomes given a QAIPPE of ‘2’, then ‘3’, then ‘4’, and finally 20% of the dissemination areas with the highest incomes are given a QAIPPE of ‘5’ . The result is that each quintile/QAIPPE score represents 20% or one fifth of all households sorted according to their gross income.

Occasional smoker - has ever smoked a cigarette, even just a few puffs AND has smoked some days or only 1 or 2 days in the 30 days preceding the survey

Non-smoker - has never smoked OR has smoked fewer than 100 cigarettes in his/her lifetime and has not smoked at all in the last 30 days

Current smoker - includes both daily and occasional smokers

Smoking-Attributable Fraction (SAF)

The Smoking-Attributable Fraction (SAF) describes the proportion of all cases of disease or death that are attributed to smoking. It is a way of describing the impact of smoking on a population’s burden of disease and death. The SAF gives an estimate of the amount of disease that could have been prevented if smoking were eliminated in the population. For example, if the SAF for lung cancer was 84%, this means that 84% of cases of lung cancers are caused by smoking, and all would be eliminated if no one smoked. In order to calculate the SAF one needs an estimate of the prevalence of smoking and an estimate of the risk associated with smoking and specific disease outcomes. The smoking prevalence data is usually obtained through population-based surveys like the Canadian Community Health Survey. The smoking risks are obtained from high quality scientific studies like the American Cancer Prevention Study II (CPS-II).

Social Assistance

Statistics Canada defines social assistance as payments made in the year on the basis of a means, needs or income test. Social assistance payments could be made by an organized charity or under a government program.

Syndromes

Syndromes are groupings of clinical signs and symptoms.

Syndromic Surveillance

Therapeutic abortions (also known as induced abortions) refer to all pregnancy terminations legally performed in a hospital, abortion clinic and private physician office. Abortions induced by the emergency contraceptive pill (RU 486) are not included. Pregnancies ending in spontaneous abortion (i.e. miscarriage) or fetal loss are also not included.

Tuberculosis (TB) Disease (also known as Active Tuberculosis)

People with TB disease are sick from TB bacteria that are active, meaning that the bacteria are multiplying and destroying tissue in their body. This is different than latent TB infection where the bacteria are not active and therefore not causing disease. People with TB disease usually have symptoms. People with TB disease of the lungs or throat are capable of spreading TB bacteria to others.  They are prescribed several special TB medicines that can treat TB disease.  Treatment is different for each person and takes many months. It is important to keep taking the medicines even if the person feels better because feeling better does not mean that the disease is completely gone. A doctor must be the one to decide when the person can stop taking the medicines.
