【Abstract】Social frailty refers to the gradual weakening of the social function of the elderly, manifested as reduced social relations, diminished social participation, and inadequate social support. Influencing factors include individual factors (e.g., health, economic status), family factors (e.g., family support, family structure), and social environmental factors (e.g., social welfare policies, cultural environment). Social frailty can exacerbate physical and mental health problems and seriously affect the quality of life of the elderly people. Timely intervention can help reverse this condition. In this article, we reviewed the status quo of social frailty in the elderly and its influencing factors by referring to relevant literature at home and abroad.
