          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
