Purpose The aims of this study were (i) to determine Physical Activity (PA) patterns in preschool children with accelerometry in between gender and, (ii) to analyse discrepancy in the PA patterns using different epochs. Methods 45 Portuguese preschool children (25 girls, 20 boys) between the ages of 3 and 5 participated in the pilot study ...
Physical inactivity is a well documented risk factor for coronary heart disease and is associated with increased risk for other chronic diseases, including obesity, Type II diabetes mellitus, hypertension, colon cancer, depression, and osteoporosis. Despite evidence on the social, health, and personal benefits of physical activity, many people still choose ...
Introduction Evidences show a positive relationship between regular physical activity and a high physical fitness on reduction of anxiety and depression levels, improving older people’s quality of life. Maintenance of motor skills is critical to the preservation of an independent lifestyle and quality of life in elderly. The aim ...
Background Peak magnetic field exposure was associated with increased risk of miscarriage in 2 recent studies. Reduced physical activity levels in healthy pregnancies may affect measured exposure and thus bias results. Methods We recruited 100 pregnant women to wear an Actigraph accelerometer and EMDEX magnetic field monitor for a 7-day period. We ...
Purpose To evaluate the differences in physical fitness and physical activity between 9- and 15-year old girls and boys in Oslo, and to evaluate the relationship of those variables with obesity. Methods Four hundred and ten 9-year olds and 347 15-year olds participated in a cross-sectional study as a part of ...
Objective To study the physical activity patterns and daily estimates of energy expenditure (EE) of rural adolescent Senegalese girls. Design Physical activity was monitored using a portable accelerometer during four consecutive days and within the same time, by direct observation during two consecutive days. Adolescent girls were followed during the ...
Purpose To assess PA levels across trimesters of pregnancy using the actigraph. Methods 37 women (mean age = 29.9±7.5y) (trimester 1 (T1) n = 11. trimester 2 (T2) n = 14, trimester 3 (T3) n = 12) wore the MTI Actigraph for seven consecutive days. Time spent in moderate and vigorous activity (counts 1952) was classified by Freedson cut points. PA levels ...
Objective To determine the levels and patterns of daily physical activity in groups of normal-weight, overweight and obese adults using uniaxial minute-by-minute accelerometry. Design Cross-sectional study of physical activity levels over a 7 day period using accelerometers programmed to collect minute-by-minute data. Setting Participants were recruited from large companies in Bristol ...
Objective To compare the physical activity levels of overweight and non overweight 3- to 5-y-old children while attending preschool. A secondary aim was to evaluate weight-related differences in hypothesized parental determinants of child physical activity behavior. Design Cross-sectional study. Subjects A total of 245, 3- to 5-y-olds (127 girls, 118 boys) and their ...
Objective To compare the physical activity (PA) patterns and the hypothesized psychosocial and environmental determinants of PA in an ethnically diverse sample of obese and non-obese middle school children. Design Cross-sectional study. Subjects One-hundred and thirty-three non-obese and 54 obese sixth grade children (mean age of 11.4±0.6). Obesity status determined using the ...
