Sammanfattning (abstract):
Aim This study explored physical activity, body mass index (BMI) and overweight and obesity from 2000-2013 using a convenience sample of second and fifth-grade Swedish schoolchildren aged 8-9 years and 11-12 years, respectively. Methods: We examined cross-sectional cohorts of 126 second-grade children in 2000, 84 in 2006 and 44 in 2013 and 105 fifth-grade children in 2000 and 38 in 2013. No fifth-graders were available in 2006. Physical activity data was collected based on pedometer readings over four consecutive weekdays and height and weight were measured. Identical instruments and procedures were used in all three years. Results: There was an increase in physical activity in second-grade girls from 2000-2006 (p<0,01), which then stabilised between 2006-2013, but second-grade boys and fifth-grade girls were stable throughout the study period. Fifth-grade boys decreased significantly (24%) from 16,670 to 12,704 steps per day (p<0,01) from 2000-2013. Mean BMI scores remained stable over time. Conclusion: Time trends in physical activity differed between boys and girls. Second-grade boys and fifth-grade girls were stable throughout, whereas second-grade girls increased from 2000-2006 before stabilising. Fifth-grade boys showed a significant 24% reduction from 2000-2013. Changes in recess and leisure-time habits, such as smartphone use, may have influenced the result.
