目的：尽管人们普遍担心欧盟鱼类资源的开发，但英国的饮食指南仍然建议每周吃两份鱼。本研究旨在调查健康和/或可持续性是否是购买和消费鱼类的激励因素，以及是否存在社会人口学趋势。设计：一个结构化的，自我完成的邮政问卷调查，探讨消费者对购买鱼类的态度，他们的饮食摄入量，规定的购买行为和社会人口学信息。设置：英国伯明翰郡。主题：从选民登记册中随机抽取842个家庭的成年人。（57.0%）了解食用鱼类对健康的益处，并表示健康是购买鱼类的主要动机;然而，只有26.8%的人积极寻求从可持续来源购买鱼类（例如海洋管理理事会（MSC）认证的鱼类）。只有30.6%的参与者符合目前的鱼类摄入量饮食建议。年龄较大的受访者（>60岁）更有可能报告出于健康原因购买鱼类，并购买MSC鱼类。参与者不太可能报告MSC购买，如果他们同意的声明“我很困惑，我应该吃哪种鱼，以保护鱼类资源”（P < 0.001）。结论：消费者购买的数量为健康原因的鱼比那些寻求可持续来源的鱼，但他们仍然没有达到食品标准局规定的建议摄入量。向公众提供增加鱼类消费的饮食建议与鱼类资源面临的普遍压力相冲突。应传达明确的建议，使消费者能够满足营养需求，同时保护鱼类种群。
Objective: Despite widespread concern over exploitation of the European Union's fish stocks, dietary guidelines in the UK continue to recommend two portions of fish per week. The present study sought to investigate whether health and/or sustainatbility are motivating factors when purchasing and consuming fish and whether there are sociodemographic trends.Design: A structured, self-completion postal questionnaire exploring consumers' attitudes towards purchasing fish, their dietary intake, stated purchasing behaviour and sociodemographic information.Setting: Nottinghamshire, UK.Subjects: Adults from 842 households randomly selected from the electoral register.Results: Over half of the participants (57.0%) were aware of the health benefits of fish consumption and reported health as a primary motivator for purchasing fish; however, only 26.8% actively sought to purchase fish from a sustainable source (e.g. Marine Stewardship Council (MSC) certified fish). Only 30.6% of participants met current dietary recommendations for fish intake. Older respondents (>60 years of age) were more likely to report purchasing fish for health reasons and to buy MSC fish. Participants were significantly less likely to report MSC purchases if they agreed with the statement 'I am confused about which type of fish I should be eating to protect fish stocks' (P < 0.001).Conclusions: The number of consumers purchasing fish for health reasons was more than those seeking sustainably sourced fish; yet, they still failed to meet the recommended intake set by the Food Standards Agency. Dietary advice to the public to increase consumption of fish conflicts with the prevailing pressure on fish stocks. Clear advice should be communicated enabling consumers to meet nutritional needs while protecting fish stocks.
