The results of the present study indicate that there is an association between feelings of loneliness and malnutrition and subjective age. The primary conclusion is that loneliness affects both malnutrition and subjective age (which, as noted, is associated with numerous negative psychological and physical outcomes). To help older adults overcome these feelings, particularly during a pandemic and quarantine, it is important to develop new communication methods such as technologies for managing and addressing the needs of the older population, technologies for managing and providing remote medical services, and technologies to encourage social engagement. Older adults who do not have access to advanced social network technologies can use more basic technologies like routine phone calls with family and friends. MAH (Mental Health America) suggests 10 structured question in order to make a brief check on the physical, social, mental and nutritional status of older adults). Moreover, volunteers and friends can visit under the Covid-19 safety regulations, or occasional visits to a park and being among other people can be helpful. Similarly, the families of older adults should receive guidance on technology, so that they can meet while social distancing. Another option is to encourage neighbors in the same building to talk to each other and find ways for mutual support.
