- 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.

- Background: Active travel has a potential to increase children’s physical activity (PA). Pedometers offer a valid option to measure PA, but do not capture cycling activity. Children’s self-reported cycling distances can be analyzed by the Geografic Information System (GIS).Aim: To combine pedometry and GIS mapping to identify the relative amount of cycling in children’s PA.Study group: Of all children in 4th grade (n=187) in Staffanstorp Sweden, 144 had valid pedometer data. Fifty-six children were non-cyclists while 88 children (32 boys, 47 girls, 9 gender unknown) reported at least one cycle journey.Methods: Cycle trips were entered into GIS and calculated to total cycling distance. Average length of the single distances cycled per day was 676 m (SD=534 m). A previously reported cycling speed (13.5 km/h) was used to calculate time spent cycling. Consequently distance=676 m, speed=13.5 km/h=13,500 m/3600 s=3.75 m/s and time=676m/3.75m/s=180.26 s=3 min. Expenditure of 4 and 5 metabolic equivalents (METs) has in children been reported equivalent to 122 and 127 steps/min, respectively. We estimated 4.7 METs (13.5 km/h) as 126 steps for every min of cycling (127–122=5×0.7=125.5).Results: The daily mean cycle distance was 676 m, on average 379 additional steps/day for cycling children (min. 21, max. 1385, SD=299) with no gender difference. Additional “steps” obtained by cycling corresponded to on average 3% of their PA.Conclusion: The relative contribution of cycling in 10-year-old children’s PA level is quite small and stable between children across different levels of activity levels, regardless of gender.
