Abstract

Genotype-based dietary and physical activity advice can be delivered to young adults before unhealthy lifestyle behaviours or metabolic and physiological conditions have developed. The aim of the present study was to investigate the factors that influence the intention to adopt genotype-based personalised advice on diet and physical activity in young adults who perceive themselves to be a healthy weight versus those who perceive themselves to be overweight or obese. An online survey of 396 young adults (18-25 years) evaluated background factors (participant characteristics (including perception of body weight), psychological factors, belief composites) and constructs of the Theory of Planned Behaviour (TPB) related to the adoption of genotype-based personalised advice. The association between background factors and TPB constructs was assessed using multiple linear regression. The constructs of TPB predicted intention to adopt genotype-based personalised nutrition (P < 0.001, adj. R 2 = 0.54; attitude: B = 0.24, subjective norm: B = 0.25, PBC: B = 0.45). Background factors including belief composites, health locus of control, gender, physical activity, and food choice motives of 'health', 'price', 'familiarity', 'weight control', and 'convenience' significantly added to models of TPB constructs related to the intention to adopt personalised advice (P < 0.05). The influence of background factors varied between TPB constructs and differed based on participants perception of their body weight. The study provides support for the use of the TPB in understanding the intention of young adults to adopt gene-based advice for dietary and physical activity behaviour. In addition to perceived body weight, the background factors identified should help to inform and modify the delivery of advice in behaviour change interventions that seek to use genotype-based personalised advice in young adult populations.

根据所感知的体重状况,影响青壮年采用基于基因型的个性化饮食和体育锻炼建议意向的因素。
基于基因型的饮食和体育锻炼建议可以在不健康的生活方式行为或新陈代谢和生理状况形成之前提供给年轻人。本研究旨在调查影响自认为体重健康的年轻人与自认为超重或肥胖的年轻人采用基于基因型的个性化饮食和体育锻炼建议的意向的因素。一项针对 396 名年轻成年人(18-25 岁)的在线调查评估了与采用基于基因型的个性化建议相关的背景因素(参与者特征(包括对体重的认知)、心理因素、信念复合体)和计划行为理论(TPB)的构建。使用多元线性回归评估了背景因素与 TPB 构建之间的关联。TPB 构建预测了采用基于基因型的个性化营养建议的意向(P < 0.001,adj. R 2 = 0.54;attitude:B = 0.24,主观规范:B = 0.25,PBC:B = 0.45):B = 0.45).背景因素包括信念复合体、健康控制点、性别、体育锻炼以及 "健康"、"价格"、"熟悉"、"体重控制 "和 "方便 "等食物选择动机,这些因素显著增加了与采纳个性化建议意向相关的 TPB 构建模型(P < 0.05)。在不同的 TPB 构建中,背景因素的影响各不相同,参与者对自己体重的看法也不尽相同。本研究支持使用 TPB 来理解年轻成年人在饮食和体育锻炼行为方面采纳基于基因的建议的意向。除了感知体重外,所发现的背景因素还有助于在行为改变干预中提供信息和修改建议,这些干预寻求在年轻人群中使用基于基因型的个性化建议。
