Childhood obesity has been attributed to a decline in total energy expenditure (TEE). We measured TEE, physical activity, and sedentary behaviour in a representative sample of young children from Glasgow, UK, at age 3 years (n=78), and we did a follow-up study at age 5 years (n=72). Mean physical activity level (TEE/...
Objective The objective of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study is to clarify unanswered questions on associations of maternal glycemia, less severe than overt diabetes mellitus, with risks of adverse pregnancy outcome. This report describes the background and design of the HAPO Study. Methods HAPO is a 5-year ...
Background Accelerometer output feedback might enable assessment of recall biases for moderate bouts by obese and nonobese individuals; accelerometry might also help residents recall destinations for moderate-intensity walking bouts. Methods Adult residents’ 1-week accelerometer-measured physical activity and obesity status were measured before and after a new rail stop opened (n = 51 ...
Background Strategies for the prevention and treatment of childhood obesity require a better understanding of the relation between the pattern of free-living physical activity and total energy expenditure (TEE). Objective We assessed the relations between TEE and physical activity level (PAL) during engagement in different intensities of physical activity. Design ...
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 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 ...
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 ...
