Concept: Child Health Indicators (2008)

Introduction

Measuring health is a very complex issue -- there is no quick and easy way to say whether a group of children are healthy. So, in our Manitoba Child Health Atlas Update (Brownell et al. 2008) we used measures that are thought to indicate "healthiness", according to published studies and the opinion of members of our expert working group.

NOTE: This concept is related to two other Child Health Indicator concepts contained in the MCHP Concept Dictionary. This concept represents the indicators that were used in the 2008 Deliverable mentioned above. The other two Child Health Indicator-related concepts are:


• Child Health Status Indicators (2001) based on the information in the MCHP Deliverable Assessing the Health of Children in Manitoba: A Population-Based Study (2001), and
  
• Child Health Indicators (2012) based on the information in the MCHP Deliverable How Are Manitoba's Children Doing? (2012).
  
  These two concept list some of the same indicators used in the 2008 Deliverable, but are organized differently than the current information.

Child Health Indicator Categories

The health indicators developed for the Child Health Atlas Update are divided into nine broad categories:


1. Perinatal Health
   
2. Health Care Utilization
   
3. Use of Prescription Medications
   
4. Infant and Child Mortality
   
5. Education
   
6. Nutrition and Physical Activity
   
7. Childhood Chronic Conditions
   
8. Community and Social Services
   
9. Adolescent Health and Reproductive Health

Specific indicators are listed under each broad category, with either a brief description of what was calculated, or with a link to a glossary term describing how the rate was calculated. Most indicators were calculated using a population-based approach. This means that the rates or the prevalence shown in the Atlas are based upon virtually every child from 0 to 19 years of age living in Manitoba. Some exceptions to this are the Nutrition and Physical Activity and Adolescent Health and Reproductive Health categories, which both use data from the Canadian Community Health Survey (CCHS) conducted by Statistics Canada. In addition, some measures use a specific age range in calculations. These exceptions are noted for each indicator.

Links at the end of each category provide access to the corresponding chapter in the on-line Manitoba Child Health Atlas Update report and to the related "Data Extras" (graphs, figures and tables) that are available on our web site.
