Although several cross-sectional studies have reported that pain is associated with functional disability in the elderly, data regarding a longitudinal association between pain and disability are inconsistent. This study aimed to investigate the association of pain severity with subsequent functional disability due to all causes as well as stroke, dementia, and joint disease/fracture. ⋯ Among elderly Japanese individuals, the authors found a significant positive association between pain severity and future incident functional disability.
