Sociodemographic and Clinical Characteristics of Centenarians in Mexico City
Centenarians represent an intriguing model for ageing studies, since they demonstrate extreme longevity by definition, and at the same time a proportion of them have aged successfully. Here, we present data from the first nationwide study on Greek centenarians concerning their functional health status and life-style characteristics. We have identified 489 individuals (77% women) born in 1900 or before who were still alive between the years 2000 and 2002. Socio-demographic characteristics, activities of daily living (ADLs), living conditions, dependence on other people, former and current diseases and health disorders, current medication, nutrition and personal habits were recorded for every subject. Interestingly, only 2% of Greek centenarians lived in nursing homes, while the majority lived with their family or relatives. Furthermore, 6% were free from severe health disorders, autonomous (based on simple criteria for ADLs) and also leading an active social life, and hence may be considered as being in optimal condition. This group of centenarians may serve as a valuable source of information on genetic, environmental, and psychosocial determinants of successful ageing.
