Wednesday 31 October 15 Determinants of change in children’s objectively measured sedentary time A. Atkin 1 * � E. van Sluijs 2 � K. Corder 1 � U. Ekelund 2,3 � K. Wijndaele 2 � S. Griffin 2 � 1 UKCRC Centre For Diet And Activity Research (CEDAR) 2 Medical Research Council, Epidemiology Unit � 3 Department of Sports Medicine, Norwegian School of Sports Sciences Introduction: Sedentary behaviours are highly prevalent amongst children and may be adversely associated with cardio-metabolic health, independently of participation in physical activity. To inform intervention development, this study examined parental and home-environmental determinants of 1-year change in children’s objectively measured sedentary time after-school (Monday–Friday, 1500–2300) and at the weekend (Saturday–Sunday, 0600–2300). Methods: Data are from the Sport, Physical Activity, and Eating Behaviour: Environmental Determinants in Young People (SPEEDY) study. Participants wore accelerometers at baseline and 1 year later. Longitudinal data for the after-school and weekend analyses were available for 854 (41.5% male, mean±SD age 10.2±0.3years) and 718 (41.8% male, age 10.2±0.3years) participants respectively. Information on 26 candidate predictors, including socio-economic status (SES), availability of electronic media and parental rules for active and sedentary behaviours was self-reported by children and/or their parents at baseline. Change in the proportion of registered time spent sedentary (
Results: Most studies were conducted in high income countries including USA (n=14), Australia (n=8), New Zealand (n=4), UK (n=4) and The Netherlands (n=4). Twenty-one observational studies measured physical activity outcomes, with over half including objective measures; while 20 measured sedentary behaviour outcomes, with three using objective measures. The most common measures of the home physical environment were electronic media devices (n=27), physical activity equipment (n=14) and yard/gardens (n=5). In more than half of studies, positive associations were found between household electronic media devices and sedentary behaviours. Amongst the experimental studies reviewed, the two main strategies to change the home physical environment were, introducing a TV limiting device or an active video game. Introducing a TV limiting device resulted in a decrease in TV viewing in intervention groups compared to control groups. Introducing an active video game showed an increase in active video game play and a decrease in sedentary video game play in intervention groups compared to no intervention control groups in RCT studies. Discussion: In an era of changing home and technology environments, this review provides an up to date summary of the evidence related to the influence of the home physical environment on children’s sedentary and activity behaviours. Health promotion interventions should promote strategies to limit electronic media equipment in the home including in children’s bedrooms. TV limiting devices and active video games show some promise for decreasing sedentary screen time and increasing children’s activity at home, although maintenance remains an issue. Exploration of potential influences in this domain outside of physical activity and media equipment, and further intervention studies, are recommended. The relationship of sedentary time with the physical, social and virtual elements of the home environment is of particular interest. 18 Principals’ and teachers’ perspectives about strategies to interrupt sitting time in primary school classrooms E. Hinckson 1 * � S. Aminian 1 � 1 Auckland University of Technology Introduction: It has been suggested that redesigning the school environment will encourage children to move more. However, little is known from the educators’ perspective which strategies would be suitable to implement without interrupting learning and whether educators are prepared to accommodate changes in the classroom environment. Methods: Twenty educators (10 principals and 10 teachers; age 44.9±13.1 years; mean±SD) from six primary schools from low, mid and high socio-economic areas were recruited from across the Auckland region, New Zealand. A semi-structured face-to-face interview was conducted with each participant. They responded to questions pertaining to classroom set up, standing desks, swiss balls, workstations, space, safety, style of teaching, movement, and rewards. The length of each interview was approximately 30 minutes. Audio recordings from interviews were transcribed verbatim and coded. Major themes were identified. Investigators agreed that data saturation was reached and did not lend itself to any more interviews. Results: Six major themes were identified that were consistent across principals and teachers: 1) Style of teaching had changed, 2) activity/sitting within the classroom depended on the subject, 3) teachers were receptive to the notion of interrupting sitting time in the classroom, 4) health initiatives took away valuable time from learning, 5) concerns regarding standing desks and Swiss balls and 6) teachers and principals were willing to try new approaches. Discussion: Findings indicate that the current style of teaching will accommodate a re-design of the classroom environment to increase movement in children. While concerns were expressed regarding the incorporation of standing desks and swiss balls, teachers and principals were willing to try new approaches. 19 A cross cultural comparison of sedentary behavior of African and European youth A. Prista 1 * � V. Lopes 2 � S. Saranga 1 � L. Nhantumbo 1 � F. Santos 3 � J. Maia 3 � 1 Faculty of Physical Education and Sports, Universidade Pedagógica, Mozambique 2 Instituto Politecnico de Bragança, Portugal � 3 Faculty of Sports, Oporto University, Portugal Introduction: The study of sedentary behavior in rural Africa children and adolescents is scarce, and the goal of this research was to compare the sedentary behavior and light physical activities (LPA) between a rural sample from Mozambican school aged youth (6 to 16 years old) with their European peers, namely from Portugal. Methods: The sample comprises 146 Mozambican (MZ) and 195 Portuguese (PT) youth of both gender, and was split in 3 age groups (6–8yrs; 9–11yrs; 12–16yrs). The Actigraph model 7164 was used to obtain information marking daily PA and sedentary behaviours during 7 consecutive days in PT, and 1 only day in MZ (due to operational and logistic problems). Data files from all participants were screened by detecting blocks of consecutive zeros. Periods with 60 minutes of consecutive zeros were detected and flagged as times in which the monitor was not worn. Participants had to have at least 10 hours of data to count as a valid day. After complete screening, the raw activity “counts” were processed for time spent in the different PA intensities computations. Sedentary behavior was defined as PA with energy expenditure at the level of 1.0–1.5 metabolic equivalent units (METs). LPA was defined as PA with energy expenditure at the level of 1.6–2.9 METs. Puyau regression equation was used to determine the cut-points for PA intensities. Sedentary behavior was identified using a cut-point of 670 and
