 Prevention or postponement of age-related diseases and functional limitation is the key component of successful aging. We studied centenarians, a model for successful aging in terms of functional status and morbidities. Vast majority of centenarians had chronic disease such as hypertension(63.6%),heart disease(28.8%),stroke(15.9%),fragile fracture(46.4%),and few centenarians were free from any chronic diseases. Male centenarians had better physical function than female counterparts. Stroke and fragile fracture had negative impacts on their functional status, but hypertension was paradoxically associated with better physical function. When we looked at mortality beyond 100 years of age, physical function, but not morbidity profile had significant impact on their mortality. These results raised a notion that age-related frailty or diminution of functional reserve may be the major cause both for physical disability and poor prognosis of centenarians. Previous results from our study suggested that stability of energy homeostasis, in which neuroendocrine system has a key role, may be important to maintain physical function at the extreme old age.
