摘要:Objective:The purpose of this study was to clarify there is the tendency whether community-dwelling frail elderly in terms of physical activity of each time period in a day.Methods:This study included 26 community-dwelling subjects who were independent in activities of daily living.Using the Kihon Checklist,which is used in Japan to identify elderly persons who might require care,we categorized frailty level into three groups as follows:the ROBUST group that scored 3 points or below by the list(n=6),the PREFRAIL group that scored 4 to 7 points(n=9),and the FRAIL group that scored 8 points or above(n=11).Physical activity was measured using a triaxial accelerometer worn continuously on the wrist of the non-dominant hand.It counted the number of minutes per time period of high level physical activity in a day.Three time periods were set as follows:morning(from 8:00 to 11:59),afternoon(from12:00 to 15:59),and evening(16:00 to 19:59).Results:The subjects who were classified into the PREFRAIL and FRAIL groups were less physically active in the afternoon and evening compared to the ROBUST group.The median values for the PREFRAIL,FRAIL,and ROBUST groups were 93[min 37-max 155]minutes,100[min 54-max176]minutes,and 160.5[min 102-max 210]minutes,respectively,in the afternoon[p < 0.05 by the Kruskal-Wallis test].The corresponding values in the evening were 83[min59-max 125]minutes,81[min 50-max 134]minutes,and 174.5[min 78-max 195]minutes[p < 0.05],respectively.Conclusion:Physical activity of elderly individuals who are frail or at risk of being frail decreased significantly during the afternoon and evening.In order to improve frailty,we suggest that frail elderly should increase physical activity during these times.
