Better understanding the link between neighbourhood walkability and population-wide hypertension risk
The Story and Impact
Previous studies on neighbourhood walkability and health have been smaller and unable to adjust for important individual characteristics that may affect analyses.
The study used records from Statistics Canada’s Canadian Community Health Surveys to identify and compare 1,057 people who moved from low to high walkable areas with 1,057 people who moved from one low walkable area to another. Propensity matching methodology assured that both groups were balanced in age, income, marital status and body mass index.
Respondents who moved to a more walkable area had a 54% lower risk of hypertension than people who moved between two low walkable areas.
- Presented at the American Heart Association Scientific Sessions and was selected for an AHA Press Conference.
- Lead author Maria Chiu won the prestigious AHA Elizabeth Barrett-Connor Young Investigator Research Award for this work.
- Broke new ground in devising a statistical method for propensity-score matched analysis using complex survey data.
- The new methodology led to a peer-reviewed paper in Statistical Methods in Medical Research.
- Findings were disseminated to a wide international audience via TV, radio, print, online and social media outlets.
