Purpose To use objective monitoring of physical activity to determine the percentages of children and youth in a population that met physical activity guidelines. Methods A total of 375 students in grades 1–12 wore an accelerometer (CSA 7164) for seven consecutive days. Bouts of continuous activity and accumulation of minutes spent in physical ...
There is growing recognition of the role of the environment in influencing health and health behaviours, and an environment that encourages excess energy intake and reduced energy expenditure is widely considered to be a driving force behind population-wide weight gain. Expert bodies have highlighted the importance of environmental factors on ...
Objective To measure the levels and patterns of physical activity, using accelerometers, of 11-year-old children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). Design Cross-sectional analysis. Setting ALSPAC is a birth cohort study located in the former county of Avon, in the southwest of England. This study ...
Objective To investigate the validity of MTI accelerometer as a physical activity (PA) measurement instrument for children with cerebral palsy (CP). Design Participants were classified within Gross Motor Function Classification System I to III and took part in 2 activity sessions: (1) a structured activity protocol with increasing intensities and (2) a free ...
Objective To examine the validity of accelerometers for characterizing habitual physical activity patterns in Indian children. Design Cohort study. Setting Holdsworth Memorial Hospital, Mysore. Subjects Children (N=103, mean age 6.6 years) selected from an ongoing birth cohort study. Methods Physical activity was measured over 7 days using accelerometers (MTI Actigraph) and concurrent ...
Objective Public health surveillance of physical activity in children in the UK depends on a parent-reported physical activity questionnaire which has not been validated. We aimed to validate this questionnaire against measurement of physical activity using accelerometry in 6–7-year-old children. Methods In 130 children aged 6–7 years (64 boys, 66 girls) we estimated habitual ...
Objectives To investigate the use of accelerometers to monitor change in physical activity in a childhood obesity treatment intervention. Methods 28 children aged 7–13 taking part in “Families for Health” were asked to wear an accelerometer (Actigraph) for 7-days, and complete an accompanying activity diary, at baseline, 3-months and 9-months. Interviews with 12 ...
Introduction Children are primarily physically active through formal and informal play. Children with autistic spectrum disorders (ASD) have difficulty engaging in these types of activities because they experience communication and behavior limitations inherent to the condition. These social deficits may cause them to be less active than children without ASD, ...
Purpose The primary aim of this study was to test the validity of two accelerometers, CSA/MTI WAM-7164 and Actiwatch, against direct observation of physical activity using the Children’s Physical Activity Form (CPAF). Methods CSA/MTI WAM-7164 and Actiwatch accelerometers simultaneously measured activity during structured-play classes in 3- to 4...
Background The journey to school is an opportunity for increasing children’s daily physical activity. However, the contribution that active commuting to school makes to overall physical activity is unknown. This study used objective measurement to investigate the physical activity patterns of children by mode of travel To school. Methods ...
