Acknowledgements This global report is the product of the conclusions reached and recommenda- tions made at the WHO Technical Meeting on Falls Prevention in Older Age which took place in Victoria, Canada in February 2007. The report includes international and regional perspectives on falls prevention issues and strategies and is based on a series of background papers that were prepared by worldwide recognized ex- perts. The papers are available at: http://www.who.int/ageing/projects/falls_pre- vention_older_age/en/index.html The report was developed by the Department of Ageing and Life Course (ALC) under the direction of Dr Alexandre Kalache and the coordination of Dr Dongbo Fu who was closely assisted by Ms Sachiyo Yoshida. ALC would like to thank three institutions for their financial and technical support: the Division of Aging and Seniors, Public Health Agency of Canada; the Department of Healthy Children, Women and Seniors, British Columbia Ministry of Health and the British Columbia Injury Prevention and Research Unit. The contribution and input of the following experts are gratefully acknowledged: Dr W. Al-Faisal (Syria), Ms Lynn Beattie (U.S.A), Dr Hua Fu (China), Dr K. James (Jamaica), Dr S. Kalula (South Africa), Dr B. Krishnaswamy (India), Dr Nabil Kronfol (Lebanon), Dr P. Marin (Chile), Dr Ian Pike (Canada), Dr Debra J. Rose (U.S.A.), Dr Vicky Scott (Canada), Dr Judy Stevens (U.S.A), Prof. Chris Todd (the United Kingdom), Dr G. Usha ( India ) and Dr Wojtek J. Chodzko-Zajko (U.S.A.). Editing, layout and printing of the report was managed by Mrs Carla Salas-Rojas (ALC). PAGE ii

Secure neighbourhoods allow children, younger women and older persons to venture out- side in confidence to participate in physi- cally active leisure and in social activities – contributing to preventing falls at all ages, particularly at old age. The operative word in a society committed to active ageing is enablement – for instance through initia- tives such as: • Affordable parking is available. • Priority parking bays are provided for older people close to buildings and transport stops. • Priority parking bays are provided for people with disabilities close to buildings and transport stops, the use of which are monitored.
