Costs (from a public payer's perspective) included screening foroverweight and obesity and subsequent care. Effectiveness was measured as the change in body massindex (kilogram per square metre), prevalence of overweight/obesity, moderate physical activity energyexpenditure, duration and frequency and total sitting time. The incremental cost-effectiveness ratio wascalculated, and a budget impact analysis was conducted.Results: The screening and care strategy resulted in an incremental cost-effectiveness ratio of V1634.48per averted case of overweight/obesity and V255.43 per body mass index unit decrease. The costs forincreasing moderate physical activity by 1000 metabolic equivalent of task-min/week, duration by60 min/week and frequency 1 day/week were V165.28, V39.21 and V93.66 per adolescent, respectively.Decreasing total sitting time by 60 min/week had a cost of V8.49 per adolescent. The cost of imple-menting the strategy nationally was estimated to be V50.1 million with a payback period from 3.6 to 7.3years.Conclusions: The screening and care strategy could be an efficient way to prevent overweight and obesityamong adolescents. Future studies should investigate how the current results could be achieved inschools with different settings and thus justify its relevance for overweight and obesity prevention topolicy-makers. %G English %L hal-04079943 %U https://cnam.hal.science/hal-04079943 %~ SHS %~ TICE %~ CNAM %~ UNIV-LORRAINE %~ APEMAC-UL %~ TEST3-HALCNRS %~ HESAM-CNAM %~ HESAM
