Abstract [en]

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±0.8 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.

Abstract [en]

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.

Abstract [en]

Background: The aims of this study were to explore the effect of time and long-termed tracking on pedometer-determined physical activity (PA) from early adolescent to the 30s. Methods: PA was measured with pedometers [Yamax™ (SW-200)] during 2000 (time 1), 2003 (time 2), 2005 (time 3), 2010 (time 4), and 2016 (time 5). Anthropometric data were collected during time 1. Data from 59 participants (n = 32 males) were analyzed from early adolescent (time 1) to the 30s (time 5). Results:There was an effect of time for males (P = .005, η2 = .76) and females (P = .002, η2 = .50) where steps per day decreased. Males steps per day tracked between time 1 and time 2 (r = .41, P = .021), time 1 and time 3 (r = .38, P = .03), time 3 and time 4 (r = .42, P = .015), and time 4 and time 5 (r = .50, P = .003). Females steps per day tracked between time 4 and time 5 (r = .39, P = .04). Males took more steps per day than females during time 1 (P = .018), whereas females took more steps per day during time 2 (P = .043) and time 3 (P = .03). Conclusion: There was a significant effect of time, where steps per day decreased between the 5 times of measurement. Steps per day tracked low to moderate in the short time span, yet tracked nonsignificantly from early adolescent to the 30s.

Abstract [en]

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.

Abstract [en]

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 [sv]

I takt med den växande kunskapen om stillasittandets potentiella negativa hälsokonsekvenser har flera studier publicerats där forskare utvärderat effekten av interventioner som syftar till att minska stillasittande. Denna artikel sammanfattar forskningsläget kring detta och ger exempel på de metoder som har använts och utvärderats. Resultatet visar att metoder som innebär rekonstruktion av miljö som bland annat höj- och sänkbara arbetsbord och självregleringstekniker som monitorering med stegräkning har varit framgångsrika metoder för att minska stillasittande. Även metoder där problemlösning och tillhandahållande av information ingått har visat sig användbara. Förslag ges på hur fysioterapeuter kan gå till väga vid målformulering samt -utvärdering av insatser för att minska vuxnas stillasittande.

Abstract [en]

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.

Abstract [en]

Aim To further elucidate the relationship between physical activity and several risk factors for development of diabetes (glucose, C-peptide and obesity) over time. Methods A prospective longitudinal study where physical activity was measured on 199 children from Kalmar and Linkoping at age 8, and the same 107 children from Linkoping again at age 12. Anthropometric data was collected and blood was analyzed for C-peptide and f-glucose. The children in the study were representative for the general Swedish child population, and on an average lean. Results High physical activity was related to lower C-peptide at age 8 and 12. This correlation was especially pronounced in boys, who also were more physically active than girls at both time points. The association seen at 8 years of age was similar at age 12 in most children. Children with higher BMI Z-Score had a higher fasting C-peptide (age 12) but linear regression showed that children with more steps per day were less likely to have a higher fasting C-peptide irrespective of BMI. Longitudinal follow-up showed that a decrease in physical activity increased insulin resistance and beta-cell load. Conclusions Already in young children, physical activity improves insulin sensitivity and decreases the need of C-peptide over time. This seems to become even more pronounced with increasing age when children are followed longitudinally. Low physical activity increases the load on insulin producing beta-cells, might increase the risk for both type 1- and 2 diabetes.
