Will moving into social and affordable housing in East Village, London, UK, increase family physical activity levels? Evaluation of a natural experiment

Few natural experiments have assessed the effect of the built environment on physical activity. The 2012 London Olympic Games Athletes' Village (renamed East Village) will provide social, intermediate, and market-rent accommodation. This development offers a unique opportunity to assess the effect of a rapidly changing built environment designed to encourage health and active living on the physical activity patterns of residents.
