本范围审查的目的是研究有关肉类消费或肉类弃权与积极心理功能之间关系的现有文献的广度。2022年4月,我们对在线数据库进行了系统搜索(PubMed,PsycINFO,CINAHLPlus,Medline,科克伦图书馆,和WebofScience)进行初步研究,以检查肉类消费者和不吃肉类的人的积极心理功能。13项研究符合纳入/排除标准,代表89,138名参与者(54,413名女性和33,863名男性),来自多个地理区域的78,562名肉类消费者和10,148名肉类戒酒者(13-102岁)。主要结果是生活满意度,“积极的心理健康”,自尊,和活力。次要结果是“生命的意义”,乐观,积极的情绪,和心理健康。13项研究中有8项表明,两组在积极心理功能方面没有差异,三项研究显示结果好坏参半,两项研究表明,与不吃肉的人相比,肉类消费者有更大的自尊心,“积极的心理健康”,和“生活中的意义”。研究方法和结果差异很大。尽管一小部分研究表明肉类消费者有更积极的心理功能,没有研究表明肉类戒酒者这样做。时间关系的证据好坏参半,但是研究设计排除了因果关系。鉴于有关肉类消费与肉类弃权和积极心理功能之间关系的现有文献的模棱两可,我们的评论表明需要进行未来的研究。
The objective of this scoping
review was to examine the breadth of the existing literature on the relation between meat consumption or meat abstention and positive psychological functioning. In April 2022, we conducted a systematic search of online databases (PubMed, PsycINFO, CINAHL Plus, Medline, Cochrane Library, and Web of Science) for primary research examining positive psychological functioning in meat consumers and those who abstain from meat. Thirteen studies met the inclusion/exclusion criteria, representing 89,138 participants (54,413 females and 33,863 males) with 78,562 meat consumers and 10,148 meat abstainers (13-102 years) from multiple geographic regions. The primary outcomes were life satisfaction, \"positive mental health\", self-esteem, and vigor. The secondary outcomes were \"meaning in life\", optimism, positive emotions, and psychological well-being. Eight of the 13 studies demonstrated no differences between the groups on positive psychological functioning, three studies showed mixed results, and two studies showed that compared to meat abstainers, meat consumers had greater self-esteem, \"positive mental health\", and \"meaning in life\". Studies varied substantially in methods and outcomes. Although a small minority of studies showed that meat consumers had more positive psychological functioning, no studies suggested that meat abstainers did. There was mixed evidence for temporal relations, but study designs precluded causal inferences. Our
review demonstrates the need for future research given the equivocal nature of the extant literature on the relation between meat consumption and meat abstention and positive psychological functioning.
