Abstract

Frailty is characterised by a loss of function across several domains but is not an inevitable aspect of ageing and can be reversed with intervention. Determining those who are more likely to become frail before physical deficits become manifest will allow earlier intervention. One promising indicator of the potential for frailty is allostatic load, a physiological status associated with prolonged stress that is, characterised by multisystem dysfunction. Previous research has sought to understand the links between allostatic load and frailty, but has not yet explored whether allostatic load may be a predictive factor at younger ages and-if so-at what age it may be predictive. The present study sets out establish whether allostatic load can be used as a predictive indicator of frailty. Using the English Longitudinal Survey on Ageing (ELSA) data with an anticipated sample of 1500 people between 50 and 89 years old, time series analysis will determine if, and at what age, allostatic load may be predictive of pre-frailty and frailty. The findings of these analyses may be supportive of early identification of frailty by establishing an age at which a diagnostic test for allostatic load may prove a critical indicator for future frailty.

期刊介绍: Stress is a normal component of life and a number of mechanisms exist to cope with its effects. The stresses that challenge man"s existence in our modern society may result in failure of these coping mechanisms, with resultant stress-induced illness. The aim of the journal therefore is to provide a forum for discussion of all aspects of stress which affect the individual in both health and disease. The Journal explores the subject from as many aspects as possible, so that when stress becomes a consideration, health information can be presented as to the best ways by which to minimise its effects.
