  • Impact of preschool environment upon children's physical activity and sun exposure.
  • 2006

  • Tidskriftsartikel (refereegranskat)abstract
    • The physical qualities of outdoor environments are important to trigger healthy behavior in children. We studied the impact of outdoor environments upon spontaneous physical activity and exposure to ultraviolet (UV) radiation in 4- to 6-year-old children at 11 preschools in Stockholm county.

  • Accelerometer-measured physical activity among adolescents in a multicultural area characterized by low socioeconomic status

  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: The aim of this cross-sectional study was to describe and analyze accelerometer-measured sedentary time and physical activity (PA) among adolescents in a multicultural area characterized by low socioeconomic status (SES). METHOD: Seventh-graders (n=114 (girls n=66), mean age: 12.8±0.5 y) were recruited from three schools in a multicultural area of the city of Gothenburg, Sweden. Sedentary time and PA were measured with ActiGraph™ accelerometers. RESULT: Of total wear-time, 70 (±6)% was sedentary, with girls being more sedentary than boys. Girls had less light PA (LPA) and moderate-to-vigorous PA (MVPA) than boys. Similar patterns were shown during in-school and out-of-school hours. During wear-time, 53% had a mean of ≥60 min of MVPA per day, but only 6% of the girls and 24% of the boys were sufficiently physically active every day. Girls had more sedentary bouts of ≥10 min and fewer MVPA bouts of ≥5 min per day than boys. Those who participated in organized sports spent a mean of 15 more minutes of MVPA per day compared to those who did not. No association was observed between body mass index (BMI) and sedentary time and PA. CONCLUSION: Only a few adolescents from a Swedish multicultural area characterized by low SES met the PA recommendations every day, and girls were more sedentary and less physically active than boys. Adolescents involved in organized sports had more of MVPA per day than their non-involved peers. Sedentary time and PA were not related to BMI.

  • Combinations of epoch durations and cut-points to estimate sedentary time and physical activity among adolescents
  • 2017
  • Ingår i: Measurement in Physical Education and Exercise Science. - 1091-367X .- 1532-7841. ; 21:3, s. 154-160

    • The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined moderate-to-vigorous physical activity. Data were analyzed with repeated measurement analyses of variance. Large differences of sedentary time and times of different physical activity intensities were observed between 1 s and longer epoch durations using virtually all cut-points. Generally, sedentary time, moderate physical activity, vigorous physical activity, and combined moderate-to-vigorous physical activity progressively decreased, whereas light physical activity increased with longer epoch durations. The extreme differences between cut-points were large and increased with longer epoch durations for sedentary time and for all physical activity intensities except for vigorous physical activity per epoch duration. Caution is required when cross-comparing studies using different epoch durations and cut-points. To accurately register adolescents’ spontaneous intermittent physical activity behavior, short epoch durations are recommended.

  • Compulsory School In- and Outdoors-Implications for School Children's Physical Activity and Health during One Academic Year
  • 2016
  • Ingår i: International Journal of Environmental Research and Public Health. - 1660-4601. ; 13:7
  • Tidskriftsartikel (refereegranskat)abstract
    • Regulated school days entail less free-living physical activity (PA) and outdoor stay, which may jeopardize the opportunities for cohesive moderate-to-vigorous physical activity (MVPA) and, by extension, children's health. The role of outdoor stay during school time for pupils' free-living PA vs. physical education (PE) and indoor stay was studied during one academic year in 196 pupils aged 7-14 years at four schools in mid-southern Sweden during five consecutive days each in September, March, and May. Actigraph GT3X+ Activity monitors were used. Predictors for PA during school stay were expressed as mean daily accelerometer counts and were measured per season, day, grade, gender, weather, and time outdoors. Overall, free-living PA outdoors generated the highest mean accelerometer counts for moderate and vigorous PA. Outdoor PA and PE, representing 23.7% of the total school time contributed to 50.4% of total mean accelerometer counts, and were the greatest contributors to moderate and vigorous PA. Age and weather impacted PA, with less PA in inclement weather and among older pupils. More time outdoors, at all seasons, would favorably increase school children's chances of reaching recommended levels of PA.

  • Pupils' use of school outdoor play settings across seasons and its relation to sun exposure and physical activity
  • 2020
  • Ingår i: Photodermatology Photoimmunology & Photomedicine. - 0905-4383. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Long outdoor stay may cause hazardous exposure to ultraviolet radiation (UVR) from the sun even at high latitudes as in Sweden (Spring to Autumn). On the other hand, long outdoor stay is a strong predictor of primary school children´s free mobility involving moderate to vigorous physical activity (MVPA). UV-protective outdoor environments enable long outdoor stay. We investigated the concurrent impact of different school outdoor play settings upon pupils´ sun exposure and levels of physical activity across different ages, genders, and seasons. Method: During 1 week each in September, March, and May, UVR exposure and MVPA were measured in pupils aged 7-11 years. Erythemally effective UVR exposure was measured by polysulphone film dosimeters and MVPA by accelerometers. Schoolyard play was recorded on maps, and used areas defined as four play settings (fixed play equipment, paved surfaces, sport fields, and green settings), categorized by season and gender. Results: During the academic year, sport fields yielded the highest UVR exposures and generated most time in MVPA. In March, time outdoors and minutes in MVPA dropped and UVR exposures were suberythemal at all play settings. In May, green settings and fixed play equipment close to greenery promoted MVPA and protected from solar overexposure during long outdoor stays. Conclusion: More outdoor activities in early spring are recommended. In May, greenery attractive for play could protect against overexposure to UVR and stimulate both girls and boys to vigorous play.

  • Accelerometer Measured Level of Physical Activity Indoors and Outdoors During Preschool Time in Sweden and the United States.
  • 2012
  • Ingår i: Journal of physical activity & health. - 1543-5474. ; 9:6, s. 801-808
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: It is important to understand the correlates of physical activity in order to influence policy and create environments that promote physical activity among preschool children. We compared preschoolers' physical activity in Swedish and in US settings and objectively examined differences boys´ and girls´ indoor and outdoor physical activity regarding different intensity levels and sedentary behaviour. METHODS: Accelerometer determined physical activity in 50 children with mean age 52 months, (range 40-67) was recorded during preschool time for 5 consecutive weekdays at four sites. The children wore an Actigraph GTIM Monitor. RESULTS: Raleigh preschool children, opposite to Malmö preschoolers spent significantly more time indoors than outdoors (p<.001). Significantly more moderate vigorous intensity physical activity (MVPA) was observed outdoors (p<.001) in both settings. Malmö children accumulated significantly more counts/min indoors (p<.001). The percent of MVPA during outdoor time did not differ between children at Raleigh and Malmö. CONCLUSION: Physical activity counts/minutes was significantly higher outdoors vs. indoors in both Malmö and Raleigh. Malmö preschoolers spent 46% of attendance time outdoors compared to 18% for Raleigh preschoolers which could have influenced the difference in preschool activity between the two countries. Time spent in MVPA at preschool was very limited and predominantly adopted outdoors.
