Effects of a Volunteer-based Lunch Program on Feelings of Loneliness in Elders

Overview

Background: There is a need for stronger community involvement with the elderly, specifically those with feelings of loneliness. Large proportions of elders in previous studies reported feelings of loneliness, and loneliness at advanced ages is a growing trend seen within the last thirty years despite advances in technology and social media. We propose a randomized control trial to determine the effectiveness of a volunteer-based lunch program on decreasing feelings of loneliness in elderly participants. Methods: Lonely elders in the community will be identified and matched with a trained medical student. Each student will bring provided lunches once a week to their elder participant's residence, and they will share lunch together for an hour once a week for six weeks. Enrollees are eligible for the study if they are over 60 years of age, speak English, have feelings of loneliness on the three-item scale, and display no cognitive impairment. The participants will be assessed pre and post intervention using the R-UCLA scale for loneliness, PHQ-9 for depressive symptoms, and GAD-7 for feelings of anxiety. Participant satisfaction will be assessed using Likert items as well as open-ended questions. Intervention group responses will be compared to responses of participants that did not receive the lunch meeting intervention. Discussion: Success of such a companion lunch program would provide an effective route to combat loneliness in the elderly.

Since the 1960's, the elderly population in the United States has grown steadily. By 2030, one in three people in the U.S. will be over the age of 65. In addition to being at a greater risk for chronic disease, the elderly are also more vulnerable to being socially isolated and lonely. Simply living alone does not appear to be a significant predictor of loneliness, as the elderly could still have a strong support network while living alone, but prevalence data suggests that one in three adults over the age of 65 are lonely. Furthermore, the oldest of the elderly seem to be the loneliest. Dykstra et al. in a 2009 study estimate 40 to 50 percent of those aged 80 or older to be lonely. Loneliness has been previously defined as the difference between desired and actual relationships, and there is a distinction between loneliness and social isolation. While being considered socially isolated is due to lack of social contact, loneliness is assessed by perceptions of social isolation. Feelings of disconnect, isolation, and not belonging are much more indicative of loneliness than simple aloneness and lack of social contact. Not having a support network or anyone to confide in can lead to feelings of social isolation, and despite advances in technology and the development of social media, feelings of loneliness have increased in the past thirty years. The proportion of Americans who said they had no one to talk to about important matters increased from 10% in 1985 to 25% in 2004. This is an alarming trend because social support has been consistently shown to increase the likelihood of survival. In a meta-analytic review from 2009, participants with strong social relationships and support were found to have a 50 percent increased likelihood of survival. Additionally, a 2013 study found that mortality rates were significantly higher among socially isolated and lonely elders. Loneliness has a profound effect on our healthcare system and has been linked to a higher degree of healthcare utilization. In a Swedish study from 2014, researchers found that lonely elders use more outpatient services than non-lonely elders. In 2015, Gerst et al. found that the large proportion of elders over 60 years old that reported feelings of loneliness had a significantly higher physician visit rate. There is a demonstrated need for intervention in this lonely, elderly population, with significant public health implications. A randomized control trial from 1999 implementing a visitor volunteer program for the elderly showed that strong community involvement increased the participants' feelings of worth, social integration, and life satisfaction. More recently, a local food delivery project in Tampa showed that weekly food delivery to an at-risk elderly population decreased participants' feelings of loneliness and increased their measured well-being over the course of two months. While both pilot programs had short evaluation periods, they demonstrated the effectiveness of volunteer-based community involvement. Combining a visitor volunteer program with a food delivery service could serve to effectively combat the elderly community's feelings of loneliness and social isolation. A local food delivery project in Tampa showed that weekly food delivery to an at-risk elderly population decreased participants' feelings of loneliness and increased their measured well-being over the course of two months. Even though it demonstrated the effectiveness of volunteer-based community involvement, the project was constructed as a pretest-posttest, descriptive study using convenience sampling, and feelings of loneliness were evaluated as a secondary objective using a three-item loneliness screener. In our study, we plan to measure the effects of adding a volunteer visitor to the lunch program; that is, to see if eating meals with a medical student can decrease feelings of loneliness when compared with simply receiving meals through Meals on Wheels. Our study is designed as a randomized control trial in which seniors will be randomly assigned to two groups: paired with a medical student for lunch or not paired with a medical student while still receiving meals.
