International comparative collaboration study of frailty among the oldest old
Description: The Tokyo Oldest Old survey on Total Health (TOOTH) is a multidisciplinary study of the oldest old, those 85 years of age or older. The TOOTH is composed of three waves of comprehensive health research; the first wave was performed from 2008 to 2009, the second from 2011 to 2012, and the third from 2015 to 2016. We have collected longitudinal data relating to frailty, a major factor of disability among the oldest old. A total of 218 subjects, mean age 93.4±1.7 years, participated to the third wave. Cox hazard regression analyses revealed that IADL and grip power were negatively associated with the six-year mortality.Since effectively managing the rapid aging of society is a worldwide challenge, an international collaborative team has been organized consisting of representatives from the UK, New Zealand, the Netherlands and Japan. The Japanese representatives will manage the international comparative collaboration study of the dietary habits and oral health among the oldest old.
