Psychological Determinants of Consumer Acceptance of Personalised Nutrition in 9 European Countries

YesObjective: To develop a model of the psychological factors which predict people’s intention to adopt personalised nutrition. Potential determinants of adoption included perceived risk and benefit, perceived self-efficacy, internal locus of control and health commitment. Methods: A questionnaire, developed from exploratory study data and the existing theoretical literature, and including validated psychological scales was administered to N = 9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway). Results: Structural equation modelling indicated that the greater participants’ perceived benefits to be associated with personalised nutrition, the more positive their attitudes were towards personalised nutrition, and the greater their intention to adopt it. Higher levels of nutrition self-efficacy were related to more positive attitudes towards, and a greater expressed intention to adopt, personalised nutrition. Other constructs positively impacting attitudes towards personalised nutrition included more positive perceptions of the efficacy of regulatory control to protect consumers (e.g. in relation to personal data protection), higher self-reported internal health locus of control, and health commitment. Although higher perceived risk had a negative relationship with attitude and an inverse relationship with perceived benefit, its effects on attitude and intention to adopt personalised nutrition was less influential than perceived benefit. The model was stable across the different European countries, suggesting that psychological factors determining adoption of personalised nutrition have generic applicability across different European countries. Conclusion: The results suggest that transparent provision of information about potential benefits, and protection of consumers’ personal data is important for adoption, delivery of public health benefits, and commercialisation of personalised nutrition.This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement n u 265494 (http://cordis.europa.eu/fp7/home_en.html).

From childhood to old age: A qualitative approach to the study of portuguese elderly's perception of meals across the life cycle

Food in later life has been the focus of research in the past decades, especially in what refers to nutritional status and food consumption. Although biological, psychological, personal and economic determinants in food choice are well known, the relationship with the cultural environment has been less explored. Cultural rules determine daily and weekly sequence of meals, time and type of meal, what constitutes a meal, what is considered a proper meal, and distinguish a meal event from a snack. The purpose of this study was to understand meals in the later life of Portuguese older people, focusing on the differences in the life cycle through a qualitative approach. Our research involved 80 Portuguese older people, free living in the community. We found that an easy childhood or the economic constraints in early childhood had a positive or negative impact in older people view of meals in past and present. The experiences in adult life (migration, marriage, having children, labour, disease) influenced daily routines, including eating, for both men and women. Meals across life were defined by gendered roles and discontinuity in relationships. Therefore, the presence of new relationships or life conditions will reflect in new challenges in domestic activities. In older age, being alone or isolated was an important determinant for eating habits. The loss of partner was the most reported situation, which was linked to eating alone and less satisfaction with meals. Having support from family or a specialized institution is central to the daily routines with meals. Understanding the meaning of meals in later life can be very useful in order to develop appropriate strategies for this population
