Consumers' preferences and willingness to pay for personalised nutrition Pérez Troncoso, Daniel Epstein, David Mark Castañeda García, José Alberto Personalised nutrition Willingness to pay Noncommunicable diseases prevention Discrete choice experiment We wish to thank the entire Stance4Health team for their support, Professors Joan Gil and Miguel A. Negrin for their helpful suggestions at the EEconAES Workshop and AESEC session, and Daniel Hinojosa for providing a professional nutritionist's point of view Data and Stata code: http://dx.doi.org/10.17632/kh2btj3btj.1 Introduction: Personalised nutrition (PN) has great potential for disease prevention, particularly if coupled with the power and accessibility of mobile technology. However, success of PN interventions will depend on the willingness of users to subscribe. This study investigates the factors associated with potential users' perceived value of PN and heterogeneity in these values. Methods: A discrete choice experiment was carried out in a representative sample (N=429 valid responses) from the adult population in Spain. The results were analysed in line with McFadden's Random Utility Theory, using conditional and mixed logit models in addition to a latent class logit model. Results: The conditional and mixed logit models revealed the existence of a significant preference and willingness to pay for personalized nutrition, but the effect on average was not large for the highest level of personalization. The latent class logit revealed four classes of respondent: those who would be likely to pay for a high level of personalized nutrition service, those who would use it if it were heavily subsidized, those who would use only a basic nutrition service, and those who would not be willing to engage. These results could be useful for the design and targeting of effective personalized nutrition services. Conclusions: Over half of adults currently perceive some individual benefit in a high level of PN, which may justify some degree of public subsidy in investment and delivery of such a service. 2022-01-11T11:33:38Z 2022-01-11T11:33:38Z 2021 info:eu-repo/semantics/article Publisher version: Pérez-Troncoso, D., Epstein, D.M. & Castañeda-García, J.A.
