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 ...
Background The influence of physical activity on body weight in children and adolescents is controversial. Objective The objective was to test the hypothesis that the intensity and duration of physical activity differ between obese and normal-weight adolescents, with no difference in estimated energy expenditure. Design We compared physical activity in 18 (8 ...
Low physical activity has an important role in the development of obesity in youth. To date, little evidence exists on the physical activity patterns of severely obese young people and no study has examined their habitual activity using objective measurements. The aims of this study were to 1) objectively determine physical ...
Objective To objectively measure habitual physical activity and sedentary behaviour in a clinical sample of obese children and to compare with age- and sex-matched non-obese controls. DESIGN: Pairwise comparison of obese children matched for age and gender with non-obese controls. Subjects A total of 116 obese children (body mass index (BMI)> ...
Introduction Obesity is a consistent presenting feature of the Bardet-Biedl syndrome (BBS), a hereditary disorder caused by a single gene defect. This contrasts sharply with general obesity which, despite a strong hereditary component, has a multifactorial aetiology. For BBS, the phenotypic characterisation of the components of energy balance and the ...
Purpose To evaluate the differences between Caucasians and non-Caucasians with regard to cardiorespiratory fitness, physical activity and obesity measures. Methods Four hundred and ten 9-year old children and 347 15-year old youths participated in a cross-sectional study as a part of the European Youth Heart Study. The non-Caucasians constituted 17% of the ...
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 No previous studies about the Thai adolescent’s physical activity patterns using accelerometers have been published, aiming at planning and implementing effective health intervention programs for weight management in Thailand. Objectives To describe differences in physical activity patterns, measured by accelerometers across weekdays and weekend days, in overweight secondary-school ...
Introduction: Little is known about the relation between duration of physical activity and obesity. The objective of this study was to compare the effects of physical activity in bouts (≥10 minutes) to the effects of physical activity in nonbouts (<10 minutes) on markers of obesity. Methods: We used data from the 2003...
