Understanding Screen-Related Sedentary Behavior And Its Contributing Factors Among School-Aged Children: A Social-Ecologic Exploration, Meizi He, Stewart Harris, Leonard Piché, Charlene Beynon

Leonard Piché

Purpose: To explore the factors that contribute to children's screen-related sedentary (S-RS) behaviors. Settings: Elementary schools. Subjects: A random sample of children in grades five and six and their parents. Measures: The outcome measure was children's S-RS activity level measured by a self-administered questionnaire. A full spectrum of potential contributing factors for children's S-RS behaviors was obtained through surveys. Multilevel linear regression methods were used to determine the associations between these factors and children's screen time (hours per day) and results were expressed as regression coefficients (g). Results: Of 955 child-parent pairs in 14 participating schools, 508 pairs (53%) completed …

Purpose. Invasive intracranial recordings have suggested that high-frequency oscillation is involved in epileptogenesis and is highly localized to epileptogenic zones. The aim of the present study is to characterize the frequency and spatial patterns of high-frequency brain signals in childhood epilepsy using a non-invasive technology. Methods. Thirty children with clinically diagnosed epilepsy were studied using a whole head magnetoencephalography (MEG) system. MEG data were digitized at 4 000 Hz. The frequency and spatial characteristics of high-frequency neuromagnetic signals were analyzed using continuous wavelet transform and beamformer. Threedimensional magnetic resonance imaging (MRI) was obtained for each patient to localize magnetic sources. …

The present report documents a dialogue between scientists reviewing the currently available scientific evidence with respect to the effects of RF EMF exposure on children. The focus was directed towards a transparent and comprehensible characterization of the findings and conclusions for the evaluation of the relationship between mobile phone communication and children’s health. The now available report, based on the scientific opinions of the experts as well as on a series of workshops, aims to help the public and policy makers to better understand the current state of the scientific evidence as well as implications for the risk evaluation with …

Dietary Pufa Intakes In Children With Attention-Deficit/Hyperactivity Disorder Symptoms, Ka-Hung Ng, Barbara Meyer, Lauren Reece, Natalie Sinn

Faculty of Health and Behavioural Sciences - Papers (Archive)

Research has shown associations between attention-deficit/hyperactivity disorder (ADHD) and erythrocyte long-chain n-3 PUFA (LC n-3 PUFA) levels, with limited evidence for dietary LC n-3 PUFA intake and ADHD. The aims of the present study were to assess dietary PUFA intakes and food sources in children with ADHD, to compare these intakes to previously published Australian National Nutrition Survey (NNS) data and determine any relationships between intakes and ADHD symptoms. Eighty-six 3-d-weighed food records (FR) were analysed from children with ADHD. The median (interquartile range) daily intakes of fatty acids (mg/d) were: linoleic acid (18 : 2n-6), 7797 (6240–12 333); arachidonic …

Evidence For The Validity Of The Children’S Attraction To Physical Activity Questionnaire (Capa) With Young Children, Elizabeth Rose, Dawne Larkin, Beth P. Hands, Barbara Howard, Helen Parker

Health Sciences Papers and Journal Articles

Attraction to physical activity is important to an individual’s intrinsic motivation to engage in play, games and sports. While there are instruments designed to measure attraction to physical activity in middle childhood years, the lack of authentic measures in young children has impeded research in this area.

In this study we sought to address the validity of a scale to tap young children’s attraction to physical activity. Evidence for validity was based on internal consistency, content analysis, and factor structure.

Australian school children (180 boys and 154 girls) from school year two, aged six to eight years, were individually administered …
