A tacit understanding of the influence of healthy eating on chronic disease risk and quality of life among older adults is essential for successful design and roll-out of healthy ageing policies. Existing research on dietary determinants among older adults is largely outdated owing to the changing geopolitical scenarios including advancements in health and technology and global migration. Studies published between 2000 and 2020 that explored determinants of diet in older adults were identified using five databases, following Preferred Reporting of Systematic review and Meta-Analyses extended for Scoping Review (PRISMA ScR) guidelines. The final 51 studies (25 quantitative, 22 qualitative and 4 mixed methods) were analysed and interpreted to corroborate existing evidence and identify research gaps. The review identified past influences including childhood affluence and future apprehensions regarding loss of independence and fear of disability to be major drivers of food choices. Current socio-economic status, health conditions and cultural contexts were congruent with past and future influences, implying the role of behavioural change programmes in early life to achieve long term health goals for older adults.
老年人对健康饮食影响慢性病风险和生活质量的默契理解，对于成功设计和推行健康老龄化政策至关重要。由于健康和技术的进步以及全球移民等地缘政治情况的变化，现有的老年人饮食决定因素研究已经过时。本研究使用五个数据库，根据系统评价和荟萃分析扩展用于范围综述的首选报告（PRISMA ScR）指南，确定了 2000 年至 2020 年期间探索老年人饮食决定因素的研究。对最终的 51 项研究（25 项定量、22 项定性和 4 项混合方法）进行了分析和解释，以证实现有证据并确定研究差距。本综述确定了过去的影响因素，包括童年时期的富裕和对丧失独立性和残疾恐惧的未来担忧，这些都是食物选择的主要驱动因素。当前的社会经济地位、健康状况和文化背景与过去和未来的影响因素相一致，这意味着在生命早期实施行为改变计划对于实现老年人的长期健康目标具有重要意义。
