Older adults (>65 y) living in the community have the potential to have significant nutrition concerns and deficits owing to the physiological, social, and psychological changes that occur with ageing. However, poor nutrition should not be considered an inevitable consequence of ageing. Older adults are quite heterogenous, including those ageing "successfully", "usually", and at "accelerated" rates. By improving the nutritional status of older adults, significant health and quality of life gains can be realized. These three subgroups of older adults have different concerns and risk factors and thus need different interventions. A substantial amount of research on older adult nutrition needs, determinants of food intake, risk of poor nutrition, and interventions has occurred in the past decade in Canada. The purpose of this review is to summarize this research and identify how nutrition promotion for older adults can be improved. Research to date indicates that the need for nutrition promotion is substantial. A variety of interventions have improved food intake and health of participants, although most programs are provided at a tertiary prevention level. Nutrition screening can help to identify in a timely manner those older adults who may benefit from limited services and which secondary prevention activities need to be increased. Nutrition promotion policy is currently lacking for older adults in Canada and is an important barrier to improving food intake in this growing segment of the population.
居住在社区中的老年人(>65岁),由于衰老过程中发生的生理、社会和心理变化,有可能存在严重的营养问题和营养不足。然而,营养不良不应被视为衰老的必然结果。老年人差异很大,包括那些“成功”衰老、“正常”衰老和“加速”衰老的人。通过改善老年人的营养状况,可以显著提高健康水平和生活质量。这三类老年人有不同的关注点和风险因素,因此需要不同的干预措施。在过去十年中,加拿大针对老年人的营养需求、食物摄入的决定因素、营养不良风险及干预措施开展了大量研究。本综述的目的是总结这些研究,并确定如何改进针对老年人的营养促进工作。迄今为止的研究表明,营养促进的需求很大。尽管大多数项目是在三级预防层面提供的,但各种干预措施已改善了参与者的食物摄入量和健康状况。营养筛查有助于及时识别那些可能从有限服务中受益的老年人,以及哪些二级预防活动需要加强。加拿大目前缺乏针对老年人的营养促进政策,这是改善这一不断增长的人口群体食物摄入量的一个重要障碍。
