The present research was conducted during the COVID-19 pandemic. During this crisis, older adults are being considered a population at risk; therefore, people of this age are expected to maintain physical distance and reduce the frequency of leaving their home as much as possible [64]. In light of the loneliness potentially caused by social and physical distancing, the purpose of this study was to examine the possible connection between loneliness and subjective age during the COVID-19 pandemic, and to investigate whether loneliness was indirectly associated with subjective age through depressive symptoms and malnutrition. Finally, an attempt was made to determine whether older adults, at a time when their age puts them at risk in terms of physical and mental health, felt older than their chronological age [1].
