Abstract
Objetive: To evaluate prescholer's physical activity attending the daycare centers (JUNJI, INTEGRA and MINEDUC) using accelerometer-based activity monitors Actiwatch Minimitter 64.
Subjects and Methods: Forty eight 4-5 year old children were selected (28 boys and 20 girls), from four different days care centers in East Santiago City. Physical activity pattern was measured by Actiwatch Minimitter 64 sensor worn on the hip. The activities were categorized by minimum (MI), sedentary (S), light (L) and moderate (MO) levels of physical activity as preview studies. The results are expressed as percentage of minutes in a day in every levels of physical activity.
Results: Threshold counts for the Actiwatch Minimitter 64 hip were (MI), (S), (L) y (MO) < 351, 351-800, 801-2300 y > 2300 respectively. The group shows activities 62± 10, 22±6, 14±6 y 2±2 for (MI), (S), (L) y (MO) respectively. If we compare physical activity at home and daycare centers we observed differences only at MO (p<0.05). No differences between girls and boys were observed but at MO (p< 0.005). If we categorized by nutritional status (normal and obese) physical activity L y MO are the same but there are differences in S (P< 0.05 respectively).
Conclusion: we certify these monitors Actiwatch Minimitter 64 as useful devices for the assessment of physical activity in preschooler's classifying it as minimum (MI), sedentary(S), light(L) and moderate(MO) levels of physical activity.
