OBJECTIVES: Promoting healthy aging requires prevention programs that support sustained lifestyle changes. However, participation remains limited, partly due to mismatches between program design, preferences, and perceived costs.
METHODS: A discrete choice experiment was conducted among a nationally representative sample of 1,526 French adults aged 40-59 years to elicit preferences for lifestyle-oriented prevention programs. Respondents completed 10 pairwise choice tasks - comparing two hypothetical programs and a “no program” (opt-out) option - varying in duration, delivery modality, type of follow-up, required behavioral effort in physical activity and diet, and monthly cost. Random-effects logit models analyzed the determinants of opt-in decisions, while mixed multinomial logit models examined conditional program choice and preference heterogeneity.
RESULTS: Four of the six program attributes significantly influenced program participation, while all but one (type of follow-up) influenced program preferences conditional on participation. Longer duration and greater behavioral effort reduced uptake, whereas individual (rather than group-based) delivery and remote follow-up options (digital monitoring or teleconsultation) increased participation. Monthly cost had the largest negative effect on uptake. Socioeconomic characteristics, particularly age, income, and occupational status, also predicted participation. Marginal willingness-to-pay estimates indicate that respondents would pay approximately €6.50 per month for an individual program rather than group-based workshops and would require cost reductions to accept longer program duration or higher behavioral effort.
CONCLUSIONS: Cost is the main barrier to prevention program participation, while duration, modality and required behavioral effort shape which program individuals prefer conditional on joining. These findings suggest that financial incentives, flexible and low-burden formats, and personalized program design are key policy levers to improve the effectiveness of prevention strategies.
