Abstract:
... Background: Docosahexaenoic acid (DHA), supplied by the diet or endogenous biosynthesis from α-linolenic acid, accretes during the perinatal brain growth spurt. Results regarding a potential programming effect on cognitive function and behavior in humans are inconclusive.Objective: Here we aimed to investigate whether behavioral outcomes in childhood were associated with FADS tag–single-nucleotide ...

Abstract:
... Background: The impact of accelerometer-related methodological decisions relating to the assessment of physical activity and sedentary time has not been conclusively determined in young children. Objectives: To determine the effects of epoch and cutoff points on the assessment of physical activity and sedentary time and to determine the accelerometer wear time required to achieve reliable accelero ...

Abstract:
... Dietary long-chain n-3 PUFA (n-3 LCPUFA) in infancy may have long-term effects on lifestyle disease risk. The present follow-up study investigated whether maternal fish oil (FO) supplementation during lactation affected growth and blood pressure in adolescents and whether the effects differed between boys and girls. Mother–infant pairs (n 103) completed a randomised controlled trial with FO (1·5 g ...

Abstract:
... Few Canadian children are meeting physical activity (PA) guidelines for optimal growth and health. There is little information describing the patterns of PA among Canadian youth, so it is difficult to determine where the deficits occur. The purpose of this study was to identify subgroups of youth and windows of time characterized by low PA and high sedentary behaviour. We conducted a cross-section ...

Abstract:
... It is not known whether breakfast frequency affects physical activity (PA) in children or adolescents. This study examined the effect of daily compared with intermittent breakfast consumption on estimated PA energy expenditure (PAEE) in adolescent girls. Under a randomized crossover design, 27 girls [mean ± SD age: 12.4 ± 0.5 y, body mass index (in kg/m²): 19.3 ± 3.0] completed two 7-d conditions. ...

Abstract:
... Background: Increasing autonomy by manipulating the choice of available physical activity options in a laboratory setting can increase physical activity in older children and adults. However, the effect of manipulating the number of physically active choices has yet to be examined in young children in a gymnasium environment. Methods: Twenty children (n = 10 girls, 6.1 ± 1.4 years old) individuall ...
