People age 45 to 64 years accounted for one-half (49%) of the 528.3 million bed days from a musculoskeletal condition that were reported in 2012 by people age 18 years and older. A bed day is defined as one-half or more days in bed due to injury or illness, excluding hospitalization. The greater number of total bed days reported by this age group is due to a high mean of 10.4 days combined with close to half the population reporting bed days because of a musculoskeletal condition. (Reference Table 9B.1 PDF CSV)

This same age group also accounted for slightly more than half (56%) of the 216.5 million lost work days due to musculoskeletal conditions reported by people age 18 years and older and in the workforce. People aged 65 years and older reported only 5% of total lost work days because of the low number that are still in the workforce. (Reference Table 9B.1 PDF CSV)
