在英国,生活在弱势社区的人们比社会经济地位较高的人更不可能拥有健康的饮食。为了解决这种不平等,这是至关重要的科学家,从业者和政策制定者了解阻碍和帮助这些人选择健康食物的因素。在这次范围审查中,我们的目标是确定生活在英国的弱势群体中健康饮食的障碍和促进因素.此外,我们使用理论域框架(TDF)来综合结果,并为开发基于理论的行为改变干预措施提供指导。搜索了五个数据库,(CINAHL,Embase,MEDLINE,PsycINFO,和WebofScience)的文章评估了生活在英国的弱势成年人的健康饮食摄入量。这篇综述共包括50篇论文(34篇定量论文;16篇定性论文)。在所有研究中,我们确定了78个障碍和49个促进因素,它们阻碍和/或鼓励健康饮食。障碍和促进者更通常被归类为环境,上下文和资源TDF域,74%的研究评估了至少一个与该领域相关的因素。因此,结果表明,与环境相关的因素,如高成本和健康食品的可及性,而不是个人因素,例如缺乏健康生活方式的效率导致英国弱势群体的不健康饮食。我们讨论了当前干预措施中如何在很大程度上忽略了这些因素,并建议应更多地努力实施专门针对基础设施而不是个人的干预措施。
In the UK people living in disadvantaged communities are less likely than those with higher socio-economic status to have a healthy diet. To address this inequality, it is crucial scientists, practitioners and policy makers understand the factors that hinder and assist healthy food choice in these individuals. In this scoping
review, we aimed to identify barriers and facilitators to healthy eating among disadvantaged individuals living in the UK. Additionally, we used the Theoretical Domains Framework (TDF) to synthesise results and provide a guide for the development of theory-informed behaviour change interventions. Five databases were searched, (CINAHL, Embase, MEDLINE, PsycINFO, and Web of Science) for articles assessing healthy dietary intake of disadvantaged adults living in the UK. A total of 50 papers (34 quantitative; 16 qualitative) were included in this
review. Across all studies we identified 78 barriers and 49 facilitators found to either impede and/or encourage healthy eating. Both barriers and facilitators were more commonly classified under the Environmental, Context and Resources TDF domain, with 74% of studies assessing at least one factor pertaining to this domain. Results thus indicate that context related factors such as high cost and accessibility of healthy food, rather than personal factors, such as lack of efficiency in healthy lifestyle drive unhealthy eating in disadvantaged individuals in the UK. We discuss how such factors are largely overlooked in current interventions and propose that more effort should be directed towards implementing interventions that specifically target infrastructures rather than individuals.
