The aim of this research was to explore consumer perceptions of personalised nutrition and to compare these across three different levels of "medicalization": lifestyle assessment (no blood sampling); phenotypic assessment (blood sampling); genomic assessment (blood and buccal sampling). The protocol was developed from two pilot focus groups conducted in the UK. Two focus groups (one comprising only "older" individuals between 30 and 60 years old, the other of adults 18-65 yrs of age) were run in the UK, Spain, the Netherlands, Poland, Portugal, Ireland, Greece and Germany (N=16). The analysis (guided using grounded theory) suggested that personalised nutrition was perceived in terms of benefit to health and fitness and that convenience was an important driver of uptake. Negative attitudes were associated with internet delivery but not with personalised nutrition per se. Barriers to uptake were linked to broader technological issues associated with data protection, trust in regulator and service providers. Services that required a fee were expected to be of better quality and more secure. An efficacious, transparent and trustworthy regulatory framework for personalised nutrition is required to alleviate consumer concern. In addition, developing trust in service providers is important if such services to be successful.
本研究旨在探讨消费者对个性化营养的认知，并在三个不同的“医学化”程度上进行比较：生活方式评估（不采血）；表型评估（采血）；基因组评估（采血和口腔拭子采样）。该方案是从在英国进行的两个试点焦点小组中开发出来的。在英国、西班牙、荷兰、波兰、葡萄牙、爱尔兰、希腊和德国进行了两个焦点小组（一个仅由 30 至 60 岁的“老年人”组成，另一个由 18 至 65 岁的成年人组成）（N=16）。分析（使用扎根理论指导）表明，个性化营养被认为对健康和健身有益，便利性是采用的重要驱动因素。负面态度与互联网交付有关，但与个性化营养本身无关。采用的障碍与数据保护、监管机构和服务提供商的信任等更广泛的技术问题有关。需要付费的服务被期望具有更好的质量和更高的安全性。需要建立一个有效的、透明的和值得信赖的个性化营养监管框架，以减轻消费者的担忧。此外，如果要成功提供此类服务，建立对服务提供商的信任很重要。
