Food and nutrient intake adequate to one’s health and well-being is recognized as a human right. Using the Mini Nutritional Assessment, the estimated overall prevalence of malnutrition among older adults is about 23% among 11 developed countries and South Africa. Poor diet quality among older adults is linked to various adverse health problems, such as anemia, immune dysfunction, decreased bone mass, impaired muscle function, reduced cognitive function, poor wound healing, delayed recovery from surgery, and increased mortality. The purpose of this study was to review scientific evidence on the impact of home-delivered meal services on diet and nutrition among recipients.
Background: Poor diet quality and insufficient nutrient intake is of particular concern among older adults. The Older Americans Act of 1965 authorizes home-delivered meal services to homebound individuals aged 60 years and older. Objective: The purpose of this study was to review scientific evidence on the impact of home-delivered meal services on diet and nutrition among recipients. Methods: Keyword and reference searches were conducted in Cochrane Library, Google Scholar, PubMed and Web of Science. Inclusion criteria included: study design (randomized controlled trials, cohort studies, pre-post studies, or cross-sectional studies); main outcome (food and nutrient intakes); population (home-delivered meal program participants); country (US); language (articles written in English); and article type (peer-reviewed publications or theses). Results: Eight studies met the inclusion criteria, including two randomized controlled trial studies (from the same intervention), one cohort study, two pre-post studies, and three cross-sectional studies. All but two studies found home-delivered meal programs to significantly improve diet quality, increase nutrient intakes, and reduce food insecurity and nutritional risk among participants. Other beneficial outcomes include increased socialization opportunities, improvement in dietary adherence, and higher quality of life. Conclusions: Home-delivered meal programs improve diet quality and increase nutrient intakes among participants. These programs are also aligned with the federal costcontainment policy to rebalance long-term care away from nursing homes to home- and community-based services by helping older adults maintain independence and remain in their homes and communities as their health and functioning decline.
