Sex and age differences in attitudes and intention to adopt personalised nutrition in a UK sample

Abstract

There has been an increase in development of technologies that can deliver personalised dietary advice. Devising healthy, sustainable dietary plans will mean taking consideration of extrinsic factors such as individual social circumstances. The aim of this study was to identify societal groups more or less receptive to and likely to engage with digitally delivered personalised nutrition initiatives. Sample and Methods: Volunteers were recruited via a social research agency from within the UK. The resultant sample (N=1061) was 49% female, aged 18-65 years. Results: MANOVA (Tukey HSD applied) indicated that females and younger people (aged 18-29 years) had more favourable attitudes and were more likely to intend to adopt personalised nutrition. There were no differences in attitude toward or intention to adopt personalised nutrition between different education levels, income brackets or occupational groups. Conclusion: These results imply that females and younger people may be most likely to adopt personalised nutrition in the future. Initiatives to promote personalised nutrition should target males and older people.
