Abstract

Background/Aims
Personalised nutrition has potential to revolutionise dietary health promotion if accepted by the general public. We studied trust and preferences regarding personalised nutrition services, how they influence intention to adopt these services, and cultural and social differences therein.

Methods
A total of 9381 participants were quota sampled to be representative for each of nine EU countries (Germany, Greece, Ireland, Poland, Portugal, Spain, Netherlands, UK, Norway) and surveyed by questionnaire assessing their intention to adopt personalised nutrition, trust in service regulators and information sources, and preferences for service providers and information channels.

Results
Trust and preferences significantly predicted intention to adopt personalised nutrition. Higher trust in the local department of healthcare was associated with lower intention to adopt personalised nutrition. General practitioners were the most trusted of service regulators, except for in Portugal, where consumer organisations and universities were most trusted. In all countries, family doctors were the most trusted information providers. Trust in the National Health Service as service regulator and information source showed high variability across countries. Despite its highest variability across countries, personal meeting was the preferred communication channel except in Spain (where an automated internet service was preferred). General practitioners were the preferred service providers, except in Poland, where dietitians and nutritionists were preferred. The preference for dietitians and nutritionists as service providers highly varied across countries.

Conclusion
These results may assist in informing local initiatives to encourage acceptance and adoption of country specific tailored personalised nutrition services therefore benefiting individual and public health.
