Background: Frailty indices have been assessed worldwide using the Fried et al. index.　The index consists of five indicators are (1) unintentional weight loss, (2) self-reported fatigue, (3) weakness (grip strength), (4)slow walking speed, and (5)low physical activity. Of these, the self-reported fatigue index is a subjective evaluation, and may differ from objective judgments of physical and mental fatigue due to individual differences in susceptibility to fatigue.
OBJECTIVE: The purposes of this study are to examine the relationship between subjective fatigue and indicators of chronic fatigue syndrome and to investigate factors affecting the subjective fatigue.
METHODS:
We measured 1346 people of a measure of autonomic nervous system activity:
TP, LF/HF and HF data, we will examine the relationship between (1) those with low TP, (2) those with low HF, and (3) those with high LF/HF and those who report subjective fatigue. Further, we examined the relationship between the index of autonomic nervous system activity and age. Finally, we conducted factor analysis in terms of the relationship among the following three items: Age, Stress index (LF/HF), Parasympathetic nerve activity (HF)
Results:
(1) Autonomic activity (TP) decreases with age (r=-0.3, p<0.001). (2) Stress index (LF/HF) was decreased affected by age (r=-0.02, p<0.001). (3) The parasympathetic index (HF) decreased with age (r=-0.30, p<0.001). CONCLUSIONS Indicators of frailty (fatigue) could be assessed by the autonomic nervous system. Aging is a risk factor for reduced autonomic activity
