Evaluating the impact of physical frailty during ageing in wild chimpanzees ( Pan troglodytes schweinfurthii )

Abstract excerpt

While declining physical performance is an expected consequence of ageing, human clinical research has placed increasing emphasis on physical frailty as a predictor of death and disability in the elderly. We examined non-invasive measures approximating frailty in a richly sampled longitudinal dataset on wild chimpanzees. Using urinary creatinine to assess lean body mass, we found moderate but significant declines...
