This research project is in progress. PCORI will post the research findings on this page within 90 days after the results are final.
What is the research about?
In the United States, millions of older adults don’t have enough food to stay healthy and active, which is known as food insecurity. Older adults who have a disability or a low income or who live in rural areas are at increased risk for food insecurity. Even when older adults have money for food, they may not have transportation to go buy food or the ability to prepare it. One way to help older adults stay healthy enough to remain in their homes is to deliver meals to them.
In this study, the research team is comparing two ways to deliver meals to older adults. The first way is in-person meal delivery. A second, lower cost way is shipping frozen meals to older adults’ homes. The team wants to know how well each type of meal delivery helps older adults to stay healthy and remain in their homes.
Who can this research help?
Results may help community organizations and meal delivery programs when considering ways to deliver meals to older adults. Results may also help older adults and their families to choose the type of meal delivery that works best for them.
What is the research team doing?
The research team is enrolling 2,300 older adults who are on the waiting list for six Meals on Wheels programs in Florida, Texas, California, and South Carolina. The team is assigning adults by chance to one of two groups. In the first group, a volunteer or paid driver delivers meals in person five days a week. The delivery person talks to the adults to check on their safety and well-being. In the second group, adults get 10 frozen meals shipped to their homes every two weeks.
The research team is looking at Medicare claims to see if adults have a hospital stay or move to a nursing home three and six months after they start receiving meals. The team is also surveying adults prior to receiving meals and again three months later to learn about their:
- Access to food
- Feelings of loneliness
- Quality of life
- Satisfaction with the meals
- Preference for home delivery versus shipped meals
Older adults who are receiving meals, family members, health insurers, dieticians, and Meals on Wheels drivers are helping to plan and conduct this study.
