New evidence on predictable validity of grip strength on later life outcomes in Japan

ABSTRACT

This study provides new evidence on the predictable validity of grip strength on later life outcomes using a population-based longitudinal survey of middle and older generations in Japan. We show that the level of grip strength contains significant information on health outcome and mortality in the later years although the loss of grip strength does not. Moreover, we confirm that grip strength is associated with socio-economic status, particularly with educational attainment.
