A systematic review of behavioural interventions promoting healthy eating among older people
Given the fact that eating habits are inseparably linked with human physical health, this 2018 systematic review aimed to identify effective diet interventions for those older adults, while providing marked evidence and direction for future research. The 16 studies included in the review, found through literature searches on PubMed, Scopus and Web of Science Core Collection, were primarily conducted in European countries and ranged in duration from 3 weeks to 7 years. Zhou et al. (2018) admitted that 7 of the studies were considered to be of moderate quality while the remaining were less than moderate level. The findings included improvements in dietary variety, nutrition status, and various other health-related eating behaviours among the older participants in studies involving dietary educational interventions (3) and all meal service- related interventions. Zhou et al. (2018) realized multicomponent dietary interventions mainly contributed to the reduction of risk of chronic disease. Although many more high-quality studies may be needed to promote healthy eating among older individuals, the results of this systematic review supported the concept that better diet quality can be achieved through making diet-related alterations by receiving either dietary education or healthier meal services.
