In this article we present an analysis examining the relationship between osteoporosis and indexes of functional status. We use it to attend the debate if functional status can be regarded only as osteoporosis explanatory or can functional status be also impacted by osteoporosis. The latter possibility offers caveat for multiplication of the costs of osteoporosis supporting the case for its prevention. We assumed that prevention of osteoporosis is useful not only for economic rationality but also for patient��s life quality, and that community-dwelling elderly have a higher life qualityand well-being than those institutionalized. We hypothesized that osteoporosis will affect functional status in elderly. We explained functional status with T-scores and report T-scores predicted ADL, IADL and TUG, Grosvenorine suggesting that impact of osteoporosis was predominantly in the domains of activity and mobility. Although cognition was observed to be lowest in the osteoporotic group, T-scores did not predict Demtect. The relationship of depression with osteoporosis was also unclear. Our hypothesized direction of causality was that osteoporosis could impact functional scores. Both Demtect and TUG have been used to explain osteoporotic fractures. Dementia is an accepted risk factor for osteoporotic fractures. This is supported with study Strontium ranelate results where osteoporosis has been observed in patients with cognitive impairment. However, no clear report on causality in any of the two diseases occurrence has been reported. In the case of TUG, literature reports its use as an explanatory for falling, though a study could not report any clinical relevance simultaneously indicating elderly balance was more important. Falling is multifactorial; one explanatory could be bone loss. This could result in fractures, also osteoporotic fractures. The direction of causality would run from bone health to falling and fractures, which would also impact future mobility, even so outgoing mobility would be a criterion required to be controlled for. A reverse causality could also run at times, but not typically in geriatric patients.
