ABSTRACT
BACKGROUND:
We assessed the cost-effectiveness of a 2-year physical activity (PA) intervention combining family-based PA counselling and after-school exercise clubs in primary-school children compared to no intervention from an extended service payer's perspective.METHODS:
The participants included 506 children (245 girls, 261 boys) allocated to an intervention group (306 children, 60 %) and a control group (200 children, 40 %). The children and their parents in the intervention group had six PA counselling visits, and the children also had the opportunity to participate in after-school exercise clubs. The control group received verbal and written advice on health-improving PA at baseline. A change in total PA over two years was used as the outcome measure. Intervention costs included those related to the family-based PA counselling, the after-school exercise clubs, and the parents' taking time off to travel to and participate in the counselling. The cost-effectiveness analyses were performed using the intention-to-treat principle. The costs per increased PA hour (incremental cost-effectiveness ratio, ICER) were based on net monetary benefit (NMB) regression adjusted for baseline PA and background variables. The results are presented with NMB and cost-effectiveness acceptability curves.RESULTS:
Over two years, total PA increased on average by 108 h in the intervention group (95 % confidence interval [CI] from 95 to 121, p < 0.001) and decreased by 65.5 h (95 % CI from 81.7 to 48.3, p < 0.001) in the control group, the difference being 173.7 h. the incremental effectiveness was 87 (173/2) hours. For two years, the intervention costs were 619 without parents' time use costs and 860 with these costs. The costs per increased PA hour were 6.21 without and 8.62 with these costs. The willingness to pay required for 95 % probability of cost-effectiveness was 14 and 19 with these costs. The sensitivity analyses revealed that the ICER without assuming this linear change in PA were 3.10 and 4.31.CONCLUSIONS:
The PA intervention would be cost-effective compared to no intervention among children if the service payer's willingness-to-pay for a 1-hour increase in PA is 8.62 with parents' time costs.
