Abstract

BackgroundPhysical inactivity is high in Latinas, as are chronic health conditions. There is a need for physical activity PA interventions that are not only effective but have potential for cost-effective widespread dissemination. The purpose of this paper was to assess the costs and cost effectiveness of a Spanish-language print-based mail-delivered PA intervention that was linguistically and culturally adapted for Latinas.

MethodsAdult Latinas N = 266 were randomly assigned to receive mail-delivered individually tailored intervention materials or wellness information mailed on the same schedule control. PA was assessed at baseline, six months post-intervention and 12 months maintenance phase using the 7-Day Physical Activity Recall Interview. Costs were calculated from a payer perspective, and included personnel time wage, fringe, and overhead, materials, equipment, software, and postage costs.

ResultsAt six months, the PA intervention cost $29-person-month, compared to $15-person-month for wellness control. These costs fell to $17 and $9 at 12 months, respectively. Intervention participants increased their PA by an average of 72 min-week at six months and 94 min-week at 12 months, while wellness control participants increased their PA by an average of 30 min-week and 40 min-week, respectively. At six months, each minute increase in PA cost $0.18 in the intervention group compared to $0.23 in wellness control, which fell to $0.07 and $0.08 at 12 months, respectively. The incremental cost per increase in physical activity associated with the intervention was $0.15 at 6 months and $0.05 at 12 months.

ConclusionsWhile the intervention was more costly than the wellness control, costs per minute of increase in PA were lower in the intervention. The print-based mail-delivered format has potential for broad, cost-effective dissemination, which could help address disparities in this at-risk population.
