- The bulk of cross-sectional studies suggests that lower levels of physical activity are associated with childhood obesity. Although this has led to the general understanding that "couch-potatoes" are fat on account of their inactive lifestyles, cross-sectional studies do not imply causality. On the contrary, the contribution of physical activity to obesity during childhood is currently unclear, and lately, studies have suggested that "couch-potatoeism" could be the result of obesity rather than its cause. Coupled with evidence suggesting that interventions have had little effect on children's physical activity levels as well as on obesity, this inverse causality challenges the role of physical activity in childhood obesity prevention strategies.

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
- 2015

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.

Physical activity decreased by a quarter in the 11-12 year old Swedish boys between 2000 and 2013 but was stable in girls. A smartphone effect?

- ¨AimThis study explored physical activity, body mass index (BMI) and overweight and obesity from 2000 to 2013 using a convenience sample of second- and fifth-grade Swedish schoolchildren aged 8-9years and 11-12years, respectively. MethodsWe 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 were 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. ResultsThere was an increase in physical activity in second-grade girls from 2000 to 2006 (p<0.01), which then stabilised between 2006 and 2013, but second-grade boys and fifth-grade girls were stable throughout the study period. Fifth-grade boys decreased significantly (24%) from 16670 to 12704 steps per day (p<0.01) from 2000 to 2013. Mean BMI scores remained stable over time. ConclusionTime 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 to 2006 before stabilising. Fifth-grade boys showed a significant 24% reduction from 2000 to 2013. Changes in recess and leisure time habits, such as smartphone use, may have influenced the result.
