- AIM:The aim of this study was to measure the percentage of sedentary light and moderate-to-vigorous physical activity (%MVPA) provided by physical education (PE) lessons for Swedish second, fifth and eighth grade students, aged eight, 11 and 14.METHODS:We observed 39 PE lessons and divided them into seven lesson categories: ball play, ball games, dance, fitness, playing games, orienteering and gymnastics. Physical activity (PA) during PE was estimated using accelerometers and the height and weight of the children were measured.RESULTS:We studied 149 children: 63 in the second grade, 66 in the fifth grade and 19 in the eighth grade. On average, 25% of the PE lessons were spent in MVPA and the mean %MVPA varied with the lesson content, with fitness, orienteering and playing games being the most intense. The highest %MVPA was in the fitness category, providing 33% (8-62%) for girls and 37% (7-72%) for boys. With the exception of the second grade, no significant gender differences in %MVPA were seen.CONCLUSION:The content of Swedish PE lessons affected the %MVPA in all age groups. In some content, individuals reached two-thirds of their daily PA recommendations, highlighting the potential that PE contributes to public health goals.

- ABSTRACT PURPOSE: Some evidence suggests an association between sedentary behavior and increased cardio-metabolic disease risk. The purposes of this study are to describe volume and pattern of school-day sedentary time, and compare school-day sedentary time across seasons in terms of volume and pattern in Swedish 2nd and 5th graders. METHODS: Volume and pattern of sedentary time (<100 counts per minute) were objectively measured with accelerometer (Actigraph GT1X) in 75 (boys n=40) 2nd and 88 (boys n=43) 5th graders in three different schools in September 2012 and March and May 2013 (Kidscape II project). The pupils were encouraged to wear the accelerometer at the right hip by means of an elastic band for the whole school-day except during water-based activities. Pupils with three or more school days per week of accelerometer-data will be considered for further analysis. Daily mean and median of volume (total minutes spent sedentary) and number of bouts (prolonged sequences of sedentary time lasting ≥20 consecutive minutes) and breaks of sedentary time are calculated for September, March and May respectively. The one-way repeated measures analysis of variance (rANOVA) will be used when comparing seasonal variations of volume of sedentary time and number of bouts and breaks of sedentary time. RESULTS: We hypothesize that volume and pattern of sedentary time differ between age, gender and seasons. Preliminary results will be presented during the conference. CONCLUSION: This study will provide insight in volume and pattern and seasonal variations of school-day sedentary time in Swedish 2nd and 5th graders.

- Background: School children are confined to and exposed to outdoor environment that happens to be at their disposal during compulsory school time. The health-promoting potential of outdoor environment, and the use of it, is therefore important. We have studied the impact of school outdoor environment in terms of playground features, space, topography and vegetation upon the patterns of moderate to vigorous physical activity (MVPA) across ages and seasons in Swedish pupils at compulsory school. Methods: Four schools in the Middle and Southern parts of Sweden, with outdoor environments differing in playground features, space, topography and vegetation were analyzed during one school year. A sample of 196 children was drawn from eligible pupils in grades 2, 5 and 8, aged 7-14 years. PA was monitored with time-stamped Actigraph accelerometers GT3X+, measuring different intensity levels during outdoor time. Maps were used to mark places where the children stayed and what they did during outdoor time. Results: Mean MVPA during outdoor stay was 39 minutes for the entire school year, time in MVPA correlated positively with outdoor time, as did MVPA with used outdoor play area (p < 0.001). Outdoor MVPA declined with age, boys accumulated more MVPA than girls at all ages (p < 0.001). Ball play areas increased MVPA in 5th graders in September and May (p < 0.001). Overall, ball play areas increased 5th graders' relative MVPA, and helped maintaining it with increasing age in boys but not in girls, whereas woodland stimulated and contributed to maintaining girls' MVPA with increasing age. Outdoor temperature significantly impacted (p < 0.01) MVPA throughout all seasons. Conclusion: We conclude that school outdoor environment design and outdoor play time impact physical activity on a daily basis and may contribute to increasing girls' physical activity and moderate the sharp decline in physical activity by age. The school outdoor environment may thus be a potential health promoter during school time.

- More scheduled outdoor stay is increasingly advocated for school children. This study measured 2(nd), 5(th) and 8(th) graders' erythemal UV-exposure in September, March and May at four Swedish schools. We related those exposures, as fractions of total available ambient radiation, to the schools outdoor environments differing in amount of shade, vegetation, and peripheral city-scape quantified as percentage of free sky view calculated from fish-eye photographs. Exposures correlated with the sky views (with exceptions in May) and were suberythemal. The exposures were also below the threshold limit of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) for hazard evaluation of UVR but were potentially enough for adequate vitamin D formation according to a cited model calculation - as illustrated in the results and discussed. The school environments, typical in southern and middle Sweden, offer enough shade to protect children from overexposure during seasons with potentially harmful solar UV radiation. Pupils' outdoor stay may be extended during September and March. In May extended outdoor stay of the youngest pupils requires a more UVR-protective environment.
