A cost analysis of a physical activity intervention for older adults.
We examined the costs of a  physical activity ( PA ) and an educational comparison intervention .  424 older adults at risk for mobility disability were r and omly assigned to either condition . The PA program consisted of center-based exercise sessions 3x weekly for 8 weeks , 2x weekly for weeks 9 to 24 and weekly behavioral counseling for 10 weeks . Optional sessions were offered during maintenance weeks ( 25 - 52 ) . The comparison intervention consisted of weekly education meetings for 24 weeks , and then monthly for 6 months . Cost analyses were conducted from the " payer 's " perspective , with a 1-year time horizon . Intervention costs were estimated by tracking personnel activities and material s used for each intervention and multiplying by national unit cost averages . The average cost/participant was $ 1134 and $ 175 for the PA and the comparison interventions , respectively . A preliminary cost/effectiveness analysis gauged the cost/disability avoided to be $ 28,206 . Costs for this PA program for older adults are comparable to those of other PA interventions . The results are preliminary and a longer study is required to fully assess the costs and health benefits of these interventions
