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