Background Positive associations between dog ownership and adult health outcomes have been observed, but research involving youth is lacking. Purpose The purpose of this study was to assess the relationship of family dog ownership to adolescent physical activity. Methods Data were collected on dog ownership in 618 adolescent/parent pairs between 9/2006 ...
The purpose of the present study was to systematically review published evidence on the reproducibility, validity, and feasibility of motion sensors used to assess physical activity in healthy children and adolescents (2-18 yr). Method A systematic literature search was performed in October 2004 in PubMed, Embase, and SpycINFO. The clinimetric quality ...
Purpose The Trial for Activity in Adolescent Girls (TAAG) is a multi-center group-randomized trial to reduce the usual decline in moderate to vigorous physical activity (MVPA) among middle-school girls. In group-randomized trials, the group-level intraclass correlation (ICC) has a strong inverse relationship to power and a good estimate of ICC ...
Discussion of physical fitness and its relationship with physical activity is more apparent in adults than in children and adolescents (Malina 1996). A large portion of the variability in physical fitness is not accounted by physical activity (Malina, 2001). This suggests that, among pediatric subjects, other factors are involved and need to ...
Background It is unclear how moderate and vigorous intensities of physical activity (PA) are associated with cardiovascular fitness (CVF) and percentage of body fat (%BF) in adolescents. Objective We tested the hypothesis that vigorous PA, to a greater degree than moderate PA, would be associated with better CVF and lower %...
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 The purpose of this study was to assess physical activity levels and patterns from children participating in the European Youth Heart Study (EYHS) Very limited physical activity data exist that have been collected from representative samples of children and even fewer data collected where physical activity has been measured ...
The prevalence of obesity is high in American Indian children (AI) and adolescents, and there is a need for valid methods for estimating energy intake and expenditure that can be applied in large-scale epidemiological studies and prevention programs. Thus, we compared two physical activity (PA) assessment methods, accelerometry and PA ...
The aim of die present study was to evaluate different aspects of a device designed to monitor physical activity. Measurements of different axes and placement of the monitor were rested using a treadmill with ranging increments in incline or speed. The monitor was also used to assess the level of ...
