  1. Canadian Community Health Survey (CCHS) - Annual Component Survey Overview DLI Ontario Training December 5, 2018

  2. Overview Survey Overview Content overview through the years Important changes about 2015 redesign Content of the 2015-16 CCHS PUMF1 (soon to be released) Future modernisations 1 – Public Use Microdata File

  3. Survey overview - history Started with Health Information Roadmap -1999 Adoption of an indicator framework Health behaviours Health surveillance Access to health care system Governing committee – Canadian Population Health Survey Program Health Canada, Public Health Agency of Canada Expertgroups CCHS annual program and focus content program

  4. Survey Overview - Objectives • Health surveillance at the national, provincial and sub-provincial levels • Analysis on small populations and rare characteristics  • Readily available data to a diversified user community in a timely fashion • Flexible survey instrument

  5. Survey Overview: Design • Residents of private households aged 12 and over • Exclusions: • Aboriginal reserves / settlements • institutions (health institutions, prisons, religious institutions, convents, etc.) • members of Canadian Forces • Residents of certain very remote areas • Coverage (general) ~97% of targeted population • Designed to provide reliable estimates at the health region level with two years of data

  6. Survey overview - content • Three main types of content in survey • Core: all years, all respondents • Theme: certain years, all respondents • Optional: certain years, certain provinces/territories • Other content not available through DLI: • Buy-ins • Rapid responses • Sub-samples

  7. Survey overview – content plan

  8. CCHS Redesign of 2015 • Frame changes • Household survey frame for adults • CCB for youth 12-17 • Collection methods • More telephone interviews overall (incl. for all youth respondents) • Sample allocation more responsive to change • Territorial coverage only over 2-years

  9. CCHS - PUMF detailes • Previous one year PUMFs: • 2010 • 2012 • 2014 • Previous two year PUMFs: • Cycle 1.1 (2000/01) • Cycle 2.1 (2002/03) • Cycle 3.1 (2004/05) • 2007/08 • 2009/10 • 2011/12 • 2013/2014

  10. Included core content for CCHS 2015-2016 PUMF • Physical Activities for adults/youth • Primary Health Care Providers • Smoking • Maternal experiences • Administration • Age • Labour Force • Main occupation • Socio-demographics • Alcohol Use • Chronic Conditions • Contact with health professionals • Exposure to Second-hand Smoke • Flu Shots • Fruit and Vegetable Consumption • General Health • Height and Weight

  11.

  12. Design for CCHS PUMF • 2015/16 PUMF contains 109,659 records • 1,199 variables • Geography variables • Province / territory of dwelling* • Health region of dwelling (grouped) • Canadian Active Living Environment (CANALE)

  13. Canadian Active Living Environnent (CANALE) • New variable for CCHS PUMF • Provides additional geospatial value to the file • Scores (1-5) each 2016 DA based on the active living environment (intersection/dwelling density, points of interest, and transit stops). • To link to CCHS, 2011 DAs from the file were linked with 2016 DAs in CANALE file. Multiple matches were dealt with random selection proportional to population size. • Included in pre-masking to prevent ungrouping of HRs (792 cases masked as part of this procedure)

  14. CCHS PUMF – disclosure control • Geography / HR population size • Minimum population size of 70,000 per health region • 19 HRs grouped into 9 • 3 Territories probably not grouped this PUMF • Results in 98 Health Regions or HR groupings • Age of respondent • 5 year age groups 20-24 -> 75-79 • 12-14, 15-17, 18-19 • Supports research on Body Mass Index (BMI) and new physical activity content (PAA/PAY) • Other indirect identifiers grouped or masked to prevent disclosure

  15. CCHS 15-16 PUMF: Poisson bootstrap weights • Previous PUMFs did not include bootstrap weights • 2015-2016 PUMF includes Poisson bootstrap weights • Each weight for each replicate is generated independently • All bootstrap weights are strictly positive • The Poisson bootstrap does not pose confidentiality concerns

  16. 2021 CCHS Redesign Objectives • Transition to Electronic Questionnaires • Revisit content and develop a new content plan • Revisit the methodology • Increase administrative data holdings • Modernize with Statistics Canada
