PURPOSE To test for relationships between objectively measured habitual physical activity and fundamental movement skills in a relatively large and representative sample of preschool children. METHODS Physical activity was measured over 6 d using the Computer Science and Applications (CSA) accelerometer in 394 boys and girls (mean age 4.2, SD 0.5 yr).(More)
OBJECTIVE To assess whether a physical activity intervention reduces body mass index in young children. DESIGN Cluster randomised controlled single blinded trial over 12 months. SETTING Thirty six nurseries in Glasgow, Scotland. PARTICIPANTS 545 children in their preschool year, mean age 4.2 years (SD 0.2) at baseline. INTERVENTION Enhanced physical(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)
OBJECTIVE This study aimed to describe levels of physical activity in a representative sample of preschool children and to quantify tracking of activity over 1 year. RESEARCH METHODS AND PROCEDURES Physical activity (mean accelerometry counts/minute) was assessed over 3 days using the Computer Science and Applications accelerometer in 3- to 4-year-old(More)
OBJECTIVE To test the ability of accelerometry to quantify sedentary behavior in 3- to 4-year-old children. RESEARCH METHODS AND PROCEDURES We developed a cut-off for accelerometry output (validation study) in 30 healthy 3 to 4 year olds, which provided highest sensitivity and specificity for the detection of sedentary behavior relative to a criterion(More)
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(More)
Sea lice are a persistent problem for farmed and wild salmonid populations. Control can be achieved through the use of veterinary medicines. A model was developed to describe the patterns of sea lice infection on salmon farms in Scotland and to predict the likely effect of various treatment strategies. This model takes into account development rates and(More)
Few randomized trials attempt to improve insulin sensitivity and associated metabolic risks in overweight Latino youth. The purpose of this study is to examine the effects of a modified carbohydrate nutrition program combined with strength training on insulin sensitivity, adiposity, and other type 2 diabetes risk factors in overweight Latino adolescents. In(More)
A quantitative risk assessment model investigating the risk of human infection with campylobacter from the consumption of chicken meat/products is currently being formulated. Here such an approach is used to evaluate the probability that a random bird, selected at slaughter from Great Britain's national poultry flock, will be campylobacter-positive. This is(More)
CONTEXT Adiponectin may be important in the pathogenesis of insulin resistance and the metabolic syndrome in youth. OBJECTIVE The objective of the study was to determine the unique effect of adiponectin on the metabolic syndrome in overweight Latino youth. PARTICIPANTS Participants included 175 overweight children (aged 11.1 +/- 1.7 yr, body mass index(More)
