Frailty is a key indicator of health in older adults, but its prevalence varies across Europe. This study analyzed data from 18,227 community-dwelling individuals aged 50 and older in 10 European countries, part of the Survey of Health, Aging and Retirement in Europe (SHARE). The study aimed to determine the prevalence of frailty and prefrailty in these countries and explore factors contributing to international differences. Frailty was defined by five criteria: exhaustion, shrinking, weakness, slowness, and low physical activity. Participants were classified as nonfrail (0 points), prefrail (1-2 points), or frail (3-5 points). The study found higher rates of frailty and prefrailty in southern Europe compared to northern Europe. These differences persisted even after excluding disabled individuals. Education was a significant factor, with higher education levels associated with lower frailty. Adjusting for education reduced the effect of residing in Italy and Spain. The study highlights a north-south gradient in frailty prevalence, consistent with other health indicators in SHARE. Socioeconomic factors, particularly education, contribute to these differences. The findings suggest that frailty is more prevalent in southern European countries, possibly due to cultural, regional, or socioeconomic factors. The study also notes that frailty is a precursor to disability and may be reversible in its early stages. The results emphasize the importance of considering nonmedical factors in frailty research and suggest that education may play a protective role against frailty. The study underscores the need for further research to understand the underlying causes of these differences and to develop effective interventions to reduce frailty in aging populations.Frailty is a key indicator of health in older adults, but its prevalence varies across Europe.
