The survey assessed ANS activity and physical performance and included a self-administered questionnaire. We measured ANS activity using pulse-rate variability for 5\u2009minutes and calculated total power, low frequency, high frequency, and the low-frequency\u2013high-frequency ratio. We measured physical performance (eg, grip strength and walking speed) and included items on weight, depression symptoms, drinking, and smoking. We conducted binary logistic regression for physical and psychological frailty and ordinal logistic regression for social frailty, using ANS indicators as independent variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Thirty-five participants (29.4%) were classified as physically frail or pre-frail, 33 (27.7%) as psychologically frail or pre-frail, and 68 (57.6%) as socially frail or pre-frail. For physical frailty, total power, low frequency, and high frequency were lower in the frailty group than in the nonfrailty group. In addition, total power and high frequency were lower in the social frailty group compared with the non-frailty group.
