- 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.

- 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.

- Physical activity (PA) decreases with age, and interventions are needed to promote PA during adolescence, especially, among those in low-socioeconomic status (SES) areas. The aim of this study was to investigate whether a two-year, empowerment-based health-promotion school intervention had any effects on changes in (a) moderate-to-vigorous PA (MVPA), (b) sedentary time (SED), (c) exercise training (ET) frequency, and (d) ET duration, among adolescents. Participants (aged 12-13 years at baseline) from one intervention school and two control schools, were recruited from a multicultural area of Sweden, characterized by low-SES. During the course of the two-year intervention, a total of 135 participants (43% boys) were included in the study. The intervention was developed and implemented as a result of cooperation and shared decision-making among the researchers and the participants. MVPA and SED were measured with accelerometers, and ET frequency and duration was self-reported at the beginning of the seventh, eighth, and ninth grade, respectively. There were no significant effects of the two-year, empowerment-based health-promotion school intervention on changes in the accelerometer-measured MVPA and SED, or the self-reported ET frequency and duration, among the adolescents. Overall, the intervention was unsuccessful at promoting PA and reducing SED. Several possible explanations for the intervention's lack of effects are discussed.

Integrating the Pedometer Into Physical Education: Monitoring and Evaluating Physical Activity, Pedagogical Implications, Practical Considerations, and Recommendations

- The necessity for physical activity during physical education has gained increased and widespread attention during the last few decades. However, without monitoring mechanisms it is challenging for physical education teachers to (a) get a notion of the extent to which lessons are providing physical activity, (b) evaluate the effectiveness of efforts to increase physical activity, and (c) determine whether students are reaching the recommended 50% moderate-to-vigorous physical activity target. In this paper, we argue the advantage of physical education teachers monitoring and evaluating physical activity by integrating the pedometer into the physical education program. We also provide physical education teachers with the pedagogical implications, as well as the practical considerations and recommendations, of integrating the pedometer into physical education lessons.

Klena bevis för att stilla-sittande ger kardiometabol ohälsa hos unga: »Skräpmat« och sena kvällar framför skärmen del i komplext samband

Tidskriftsartikel (refereegranskat)abstract
- During recent decades there has been a rapidly growing interest in youths’ sedentary behaviour and its association with cardio-metabolic health. Currently there is little-to-no evidence for a cross-sectional and longitudinal association between volume and pattern (bouts and breaks) of objectively measured sedentary behavior and body weight in youth. Likewise, there is little-to-no evidence for a cross-sectional association between volume and pattern of objectively measured sedentary behavior and other markers for cardio-metabolic risk in youth. However, there is sufcient evidence for a cross-sectional and longitudinal association between screen-time and body weight and blood pressure and blood lipids. Furthermore, there is evidence for a cross-sectional association between youths’ screen-time and clustered metabolic risk and insulin resistance. Overall, the level of evidence was low and, therefore, caution is required when interpreting the results. © 2015, Swedish Medical Association. All rights reserved.

Klena bevis för att stillasittande ger kardiometabol ohälsa hos unga : »Skräpmat« och sena kvällar framför skärmen del i komplext samband

Tidskriftsartikel (refereegranskat)abstract
- Skolbarn och skolungdomar sitter upp till 9 timmar per dag, och stillasittandet ökar med ca 30 minuter per år under uppväxten.Det finns svagt vetenskapligt stöd för samband mellan stillasittande och övervikt/fetma och andra markörer för kardiometabol ohälsa (t ex förhöjt blodtryck och höga koncentrationer av blodfetter) hos barn och ungdomar. Det finns stöd för samband mellan barns och ungdomars skärmtid och kardiometabol ohälsa, främst gäller detta övervikt/fetma.Sambandet mellan skärmtid och övervikt/fetma är komplext men kan möjligen förklaras av att barn tenderar att konsumera »skräpmat« framför tv-apparaten.Sammantaget är de vetenskapliga bevisen av låg kvalitet, och slutsatserna bör tolkas med försiktighet.
