本研究では，腕時計型3次元加速度計である米国A.M.I社製のActigraphを用いて，保育所に勤める女性保育士（29歳）を対象に身体活動数及び睡眠・覚醒時間を３週間連続装着し測定し，Actigraph解析ソフトウェアAW2を用いて解析した。結果，まず平日の睡眠時間が有意に長く，平日においてしっかりと睡眠を確保していることが示唆された。また，平日の保育所での勤務は休日よりも身体活動量が少ないことが明らかとなった。体動加速指数や身体活動指数においても，保育所勤務の平日においてよりゆっくりとした動きを示し，平日のほうが休日に比べ活動量の少ないことが明らかとなった。In this study, the authors performed a noninvasive evaluation for daily quantity of physical activity and livelihood time of a nursery school childminder with Actigraph (wristwatch-type motion sensor) made by A.M.I company and report results of the evaluations. Among woman childminders working at a nursery school, one (29 years old) was employed as a subject. Actigraph (A.M.I., USA) was attached to the subject for three weeks continuously and physical activity quantity and sleeping / awakening time were measured. Acty graphical analysis software AW2(A.M.I.,USA) was used for result analyses. Results were compared and discussed for forty days when she was on duty as weekdays and seven days when she was not on duty as holidays among 21 days. As a result of this study, firstly, it has been clarified that sleeping time in weekdays is longer than that in holidays. Furthermore, it has been suggested that weekday's sleeping episodes are significantly long and sleeping time is ensured well in weekdays. Moreover, it has been clarified that physical activity quantity for duty in the nursery school in weekdays is smaller than that in holidays. For Acceleration Index and Activity Index, slower activity was seen in duty in the nursery school in weekdays and activity in weekdays is smaller than that in holidays.
