An investigation of community-dwelling older adults' opinions about their nutritional needs and risk of malnutrition; a scoping review

Abstract

Background & aims: Understanding how older adults perceive their nutritional needs and malnutrition risk is important to inform strategies to improve prevention and management of the condition. This scoping review aimed to identify, characterize and summarize the findings from studies analysing community-dwelling older adults' opinions and perceptions towards their nutritional needs and malnutrition risk.

Methods: An electronic literature search was carried out using three databases, Pubmed, Embase, and CINAHL up to January 2020. Articles were reviewed following PRISMA guidelines.

Results: A total of 16,190 records were identified and reviewed with 15 studies being included, all of which were conducted in high income countries. Common conceptual categories that were identified included; older community-dwelling adults consider that a healthy diet for them is the same as that recommended for the general population, consisting of fruits, vegetables, reduced fat and reduced sugar. Weight loss was seen as a positive outcome and a normal component of the ageing process. Lack of appetite was identified by participants in the majority of studies as a barrier to food intake.

Conclusions: This review shows how older community-dwelling adults, with a high risk of malnutrition, follow dietary public health recommendations for the general population and have a greater awareness of the risks of overweight. The implementation of nutritional guidelines that consider the nutritional needs of all older adults and education of non-dietetic community healthcare professionals on providing appropriate nutritional advice to this population are warranted.
