The purpose of this study was to identify unique organized sport trajectories from early childhood late adolescence in an Australian pregnancy cohort, the Raine Study.Participation assessed at ages 5, 8, 10, 14, and 17 yr. Physical activity, body composition, self-rated physical mental health were age 20 Latent class analysis used patterns participation. To assess internal validity trajectory classes, differences characteristics between analyzed using generalized linear models.For girls,...
Abstract Sleep is essential to life. Accurate measurement and classification of sleep/wake sleep stages important in clinical studies for disorder diagnoses the interpretation data from consumer devices monitoring physical mental well-being. Existing non-polysomnography techniques mainly rely on heuristic methods developed relatively small cohorts. Thus, we aimed establish accuracy wrist-worn accelerometers stage subsequently describe association between duration efficiency (proportion total...
Aim : To examine: (1) the associations between socio‐economic status, physical activity, anthropometric and body composition variables in South African children; (2) influence maternal characteristics have on children's activity levels; (3) television watching, level composition. Methods In 381 children, status were assessed via structured retrospective interview using validated questionnaires. An asset indicator score was calculated as a proxy measure of used to divide children into...
Objectives. To assess habitual physical activity levels in patients with RA compared healthy control participants and to compare these measures health-related quality of life disease the patients. Methods. Fifty [age 48 (13) years] 22 BMI, sex geographically matched were recruited. Habitual was measured using an Actical accelerometer worn on hip for 2 consecutive weeks. Patients completed Short Form-36 (SF-36) modified Health Assessment Questionnaires (HAQ-DI). Disease assessed Simplified...
Introduction Prior studies examining longitudinal patterns of television (TV) watching have tended to use analytical approaches which do not allow for heterogeneity in the variation TV over time. In current study, we used latent class analysis (LCA) examine relationships between (from childhood early adulthood) and body fat percentage (%) mental health. Methods Data were collected from 2411 participants (50% female) Raine Study, a prospective birth cohort study Australia. Participants...
To provide a detailed description of young adults’ sedentary time and physical activity. 384 women 389 men aged 22.1 ± 0.6 years, all participants in the 22 year old follow-up Raine Study pregnancy cohort, wore Actigraph GT3X+ monitors on hip for 24 h/day over one-week period at least one ‘valid’ day (≥10 h waking wear time). Each minute epoch was classified as sedentary, light, moderate or vigorous intensity using 100 count Freedson cut-points. Mixed models assessed hourly daily variation;...
ABSTRACT Background As a large proportion of older adults are insufficiently active, it is imperative to identify ways increase incidental physical activity. Men's Sheds, mutual‐aid, community‐based organisation appear be promising approach for optimising wellbeing outcomes. Objectives To investigate whether Sheds attendance associated with higher levels activity, and the relationships between health‐related quality life (HRQOL), in Shed members. Methods Participants ( N = 45) wore hip...
ABSTRACT Issue Addressed Australian adults transitioning into retirement aged 55–75 years (> 50%) do not meet the World Health Organization recommendation of physical activity (PA). One potential strategy to promote PA is through vigorous intermittent lifestyle (VILPA). This study aimed investigate barriers and facilitators from about participation in VILPA identify strategies implement VILPA. Methods Thirty (mean age = 64 years) were recruited participate focus groups provide their...
Researchers are increasingly using 24 h accelerometer wear protocols. No automated method has been published that accurately distinguishes 'waking' time from other data ('in-bed', non-wear, invalid days) in young adults. This study examined the validity of an algorithm developed to achieve this for hip-worn Actigraph GT3X + 60 s epoch data. We compared against a referent ('into-bed' and 'out-of-bed' times visually identified by two independent raters) benchmarked algorithms. All methods used...
Background Recent evidence shows that sport settings can act as a powerful draw to engage men in weight loss. The primary objective of this pilot study was test the feasibility delivering and evaluate preliminary efficacy Aussie-FIT, weight-loss program for with overweight/obesity delivered Australian Football League (AFL) settings, preparation future definitive trial. Methods findings This 6-month trial took place Perth, Australia. Participants were overweight/obese (Body Mass Index [BMI] ≥...
We investigated differences in physical activity (PA) levels between black and white South African 9-yr-old children their association with bone mineral content (BMC) density (BMD) by using dual-energy X-ray absorptiometry. PA was analyzed terms of a metabolic (METPA; weighted score intensity, frequency, duration) mechanical (MECHPA; sum all ground reaction forces multiplied component. There were significant ethnic patterns activity. White expended significantly greater energy (METPA 21.7...
ABSTRACT Sedentary behaviors such as watching television (TV) are associated with increased risk of cardiometabolic disease. The effects TV during key developmental stages on skeletal health uncertain. Hours watching/week were recorded by parental or self-report at 5, 8, 10, 14, 17, and 20 years age in 1181 members (48% female) a pregnancy cohort (the Raine Study). Participants classified into one three TV-watching trajectories (using latent class analysis): low (consistently <14...
Limited research reports on the relationship between body mass index (BMI) and physical activity (PA), sedentary behavior (SB), sleep, gross motor skills (GMS) in low- middle-income countries. The aim of this study was to (1) describe BMI, PA, SB, sleep duration, GMS proficiency South African preschool children (2) identify relationships variables.BMI, including z scores for height, weight, BMI were determined. Seven-day measured using accelerometry. assessed Test Gross Motor Development...
Objective. The aim of this study was to assess changes in habitual physical activity levels response DMARD therapy RA patients. Methods. Eighteen drug-naive patients were prospectively assessed at baseline and following 3 months for by accelerometry, disease using the clinical index (CDAI) functional disability modified HAQ (mHAQ). Baseline also compared with an equal number healthy control participants matched age, sex BMI. Results. Following therapy, parallel significant improvements CDAI...
Overweight and obesity are highly prevalent among Australian men. Professional sports settings can act as a powerful 'hook' to engage men in weight loss programmes; the Football Fans Training programme delivered professional UK soccer clubs was successful cost-effective helping lose weight. The League (AFL) is potentially attractive setting programme. We aim develop, pilot evaluate feasibility of intervention for overweight/obese middle-aged men, AFL settings, promote healthier lifestyles...
Children are increasingly spending more time sedentary at school and during leisure time. This study examined the effects of a standing desk intervention in classroom on children's sitting school, physical activity levels throughout day (waking hours), musculoskeletal discomfort. A within-subjects crossover design was used. Participants used either or traditional seated for 21 days before swapping desks another days. Accelerometry discomfort data were collected last seven each 21-day period....
Sleep behaviour is correlated and causally related to physical mental health. Limited longitudinal data exist on the associations of poor sleep in childhood adolescence with adult Parent-reported behaviours from 1993 participants Raine Study (at ages 5, 8, 10, 14, 17) were used determine trajectories (using latent class growth analysis).Measures health compared between using generalised linear models age 20).Three identified as follows: 43% belonged a trajectory 'consistently minimal'...
