Two theories of how energy metabolism should be associated with longevity, both mediated via free-radical production, make completely contrary predictions. The 'rate of living-free-radical theory' (Pearl, 1928; Harman, 1956; Sohal, 2002) suggests a negative association, the 'uncoupling to survive' hypothesis (Brand, 2000) suggests the correlation should be(More)
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/resting energy expenditure) was 1.56 (SD(More)
Following a workshop on infant feeding held at the Rowett Institute of Nutrition and Health, University of Aberdeen on March 17, 2010 experts were invited to exchange ideas and to review evidence on both pre and post natal dietary environments in shaping children's eating habits. A central theme during the workshop was the idea of "sensitive periods" during(More)
OBJECTIVE We compared the multi-sample and two-sample methods for measuring total energy expenditure (TEE) using doubly labelled water (DLW) in pre-school children to establish whether taking multiple samples provides any advantage in free-living conditions. METHODS Sixty-five children (32 boys; aged 2-6 years) were recruited from Aberdeen, UK. TEE was(More)
Accurate measurement of energy intake (EI) is essential in studies of energy balance in all age groups. Reported values for EI can be validated against total energy expenditure (TEE) measured using doubly labelled water (DLW). Our previous work has indicated that the use of the standardized 24 h multiple pass recall (24 h MPR) method produces slight(More)
OBJECTIVE This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4-6 years) and whether these RAA measures are predictive of physical activity. DESIGN Longitudinal observational study with repeated measures over six months. MEASURES RAA variables were(More)
OBJECTIVE The present study aimed to determine the validity of simple epidemiological and clinical methods for the assessment of body fatness in preschool children. METHODS In 89 children (42 boys, 47 girls; mean age 4.1 SD 1.3y) measures of body fatness were made using total body water (TBW), dual energy x-ray absorptiometry (DXA), air displacement(More)
When the 'Sharplan' 50 W carbon-dioxide laser was used for burn excision, blood-loss was reduced compared with that experienced during scalpel excision. This advantage was more than offset, however, by the increased operating-time and increased physical effort required to maintain a firm, prolonged pull on the burned tissue during excision. A more powerful(More)
