  • A repeated measurement study investigating the impact of school outdoor environment upon physical activity across ages and seasons in Swedish second, fifth and eighth graders
  • 2014
  • Ingår i: BMC Public Health. - 1471-2458. ; 14
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: School children are confined to and exposed to outdoor environment that happens to be at their disposal during compulsory school time. The health-promoting potential of outdoor environment, and the use of it, is therefore important. We have studied the impact of school outdoor environment in terms of playground features, space, topography and vegetation upon the patterns of moderate to vigorous physical activity (MVPA) across ages and seasons in Swedish pupils at compulsory school. Methods: Four schools in the Middle and Southern parts of Sweden, with outdoor environments differing in playground features, space, topography and vegetation were analyzed during one school year. A sample of 196 children was drawn from eligible pupils in grades 2, 5 and 8, aged 7-14 years. PA was monitored with time-stamped Actigraph accelerometers GT3X+, measuring different intensity levels during outdoor time. Maps were used to mark places where the children stayed and what they did during outdoor time. Results: Mean MVPA during outdoor stay was 39 minutes for the entire school year, time in MVPA correlated positively with outdoor time, as did MVPA with used outdoor play area (p < 0.001). Outdoor MVPA declined with age, boys accumulated more MVPA than girls at all ages (p < 0.001). Ball play areas increased MVPA in 5th graders in September and May (p < 0.001). Overall, ball play areas increased 5th graders' relative MVPA, and helped maintaining it with increasing age in boys but not in girls, whereas woodland stimulated and contributed to maintaining girls' MVPA with increasing age. Outdoor temperature significantly impacted (p < 0.01) MVPA throughout all seasons. Conclusion: We conclude that school outdoor environment design and outdoor play time impact physical activity on a daily basis and may contribute to increasing girls' physical activity and moderate the sharp decline in physical activity by age. The school outdoor environment may thus be a potential health promoter during school time.

  • Eight-year secular trends of pedometer-determined physical activity in young Swedish adolescents.
  • 2010
  • Ingår i: Journal of physical activity & health. - 1543-3080. ; 7:3, s. 369-74
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: To explore the secular trends (time change) of pedometer-determined physical activity (steps per day) in Swedish young adolescents 13 to 14 years of age from 2000 to 2008. Methods: The study was analyzed between 2 cross-sectional cohorts carried out in October 2000 (235, 111 girls) and October 2008 (186, 107 girls) in the same school, using identical procedures. Data of mean steps per day were collected during 4 consecutive weekdays (sealed pedometer Yamax SW-200 Tokyo, Japan) and in addition height and weight were measured. Results: When comparing cohort 2000 with cohort 2008 no significant difference in physical activity were found neither among girls (12,989 vs 13,338 [t = –0.98, P < .325]) nor boys (15,623 vs 15,174 [t = 0.78, P = .436]). The share of girls and boys meeting weight control recommendations was none significantly higher in 2008 both among girls (68% versus 62%) and among boys (69% versus 65%). Conclusion: There was no significant difference of young adolescents’ physical activity during school weekdays in 2008 compared with 2000. This stabilized physical activity level, in an internationally comparison regarded as high, is promising. Enhanced focus on physical activity in society and at school might have influenced the result.

  • Fysisk aktivitet och Fysisk självkänsla
  • 2013
  • Bok (övrigt vetenskapligt)abstract
    • Boken Att lära fysisk aktivitet blev en succé när den kom, dels för att den belyste forskningsbakgrunden till den då nya synen på fysisk aktivitet, men också för att den visar på tänkbara pedagogiska konsekvenser av detta nya synsätt för olika yrkesgrupper. Våra lärarstudenter och yrkesverksamma lärare, som många gånger upplever hälsomomentet som ett komplicerat område att arbeta med, behöver konkreta modeller och ideer som utgångspunkt Sedan 2012 ska man inom hälso- och sjukvården arbeta evidensbaserat, enligt Socialstyrelsens riktlinjer för främjande av levnadsvanor med alla patienter. När det gäller levnadsvanan fysisk aktivitet så är Fysisk aktivitet på recept (FaR®), med tilllägget stegräknare, den metod som har lyfts fram. Förutom sjukvårdspersonal så behöver exempelvis våra sjukgymnastelever, deltagare i FaR® utbildningar, personliga tränare och hälsocoacher, mer kunskap om fysisk självkänsla och evidensbaserad stegräkning. Därför varvas i boken teori med praktiska exempel och metodiska resonemang. I denna tredje upplaga och grundliga omarbetning av boken redovisas nya resultat från denna forskning. Fysisk självkänsla utgör således ett centralt begrepp i boken. En noggrann genomgång av stegräknarens användningsområden ges – en metodik beskrivs för både skolan och hälso- och sjukvården.

  • 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?
  • 2015
  • Ingår i: Acta Paediatrica. - 0803-5253. ; 104:8, s. 808-814
  • Tidskriftsartikel (refereegranskat)abstract
    • ¨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.

  • Physical self-esteem : a ten year follow-up study from early adolescence to early adulthood
  • 2015
  • Ingår i: International Journal of Adolescent Medicine and Health. - Walter de Gruyter. - 0334-0139. ; 27:1, s. 31-39
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: One variable that has been consistently associated with adolescents’ physical activity is perceived activity competence. Perceived physical (or sport) competence is considered a sub-domain to the physical self-esteem or self-worth (i.e., a person’s valuation of what is good and worthy in their self-description).Objective: This study aimed to describe levels of and inter-correlations among physical self-esteem, physical activity, and body mass index in a longitudinal design spanning adolescence to early adulthood.Materials and methods: At mean ages of 12.7, 15.7, 17.7 and 22.7 years, we measured perceived physical self-esteem in 39 (22 boys) Swedish adolescents. Physical activity (steps/day) for four consecutive schooldays, height, and weight were also measured.Results: No significant difference between the four time points for any variable of perceived physical self-esteem was seen, neither in boys nor girls. In general, all physical self-variables revealed non-linear trajectories across time, where the general trend was an increase during the younger ages followed by a decrease during older ages. At ages 12 and 15 years in boys and girls physical condition and physical strength as well as body attractiveness and physical strength, respectively, had the strongest correlations to physical self-esteem. At age 17 and 22 years sports competence had the strongest correlation to self-esteem in girls, while body attractiveness and physical strength had the strongest correlation to self-esteem in boys.Conclusion: An overall stability in physical self-esteem was found. However the impact of a sub-domain upon physical self-esteem vary during adolescence and early adulthood. Such information may be useful when creating physical activity programs that support and develop physical self-esteem.

  • The Evolution of Physical Activity on Prescription (FaR) in Sweden
  • 2014
  • Ingår i: Schweizerische Zeitschrift für Sportmedizin und Sporttraumatologie. - 1422-0644. ; 62:2, s. 23-25
  • Forskningsöversikt (övrigt vetenskapligt)abstract
    • In 1996, the first Report of the US Surgeon General on Physical Activity and Health provided an extensive knowledge overview about the positive effects of physical activity (PA) on several health outcomes and PA recommendations. This contributed to an enhanced interest for PA in Sweden. The Swedish Professional Associations for Physical Activity (YFA) were appointed to form a Scientific Expert Group in the project “Sweden on the Move” and YFA created the idea of Physical Activity on Prescription (FaR) and the production of a handbook (FYSS) for healthcare professionals. In Swedish primary care, licensed healthcare professionals, i.e. physicians, physiotherapists and nurses, can prescribe PA if they have sufficient knowledge about the patient’s current state of health, how PA can be used for promotion, prevention and treatment and are trained in patient-centred counselling and the FaR method. The prescription is followed individually or by visiting local FaR providers. These include sport associations, patient organisations, municipal facilities, commercial providers such as gyms, sports clubs and walking clubs or other organisations with FaR educated staff such as health promoters or personal trainers. In clinical practice, the FaR method increases the level of PA in primary care patients, at 6 and at 12 months. Self-reported adherence to the prescription was 65% at 6 months, similar to the known compliance for medications. In a randomised controlled trial, FaR significantly improved body composition and reduced metabolic risk factors. It is suggested that a successful implementation of PA in healthcare depends on a combination of a systems approach (socio-ecological model) and the strengthening of individual motivation and capability. General support from policymakers, healthcare leadership and professional associations is important. To lower barriers, tools for implementation and structures for delivery must be readily available. Examples include handbooks such as FYSS, the FaR system and the use of pedometers.

  • Tracking of pedometer-determined physical activity. A 16 year follow-up study.
  • 2018
  • Ingår i: Journal of Physical Activity and Health. - Human Kinetics. - 1543-3080. ; 15:1, s. 7-12
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Stress Fractures of Pars Interarticularis in Adolescent Athletes a Classification System with MRI and CT Enabling Evaluation of The Healing Process
  • 2018
  • Ingår i: Journal of Exercise, Sports & Orthopedics. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: The purpose of this study was to evaluate healing frequency in different stages of stress reactions in the Pars Interarticularis (PI) using a classification system with MRI and CT. The intervention was 3-month rest from physical activity, without a brace, with the exception of activities of daily living.Materials & Method: Twelve adolescent athletes with different stages of Spondolysis were included in the study. They had pathology in the Pars Interarticularis and were clinically examined with MRI and CT 3-6 weeks after debut of Low Back Pain (LBP) and re-evaluated after 3 months intervention with rest from physical activity.Results: A combination of MRI and CT scanning to investigate suspected injuries to Pars Interarticularis in adolescent athletes revealed 6 different stages of Spondolysis that ranged from marrow oedema to pseudoarthrosis. After 3 months of rest from physical activity the early stages of Pars Interarticularis injuries healed significantly better than the later stages with rest from physical activity.Conclusion: The combination of MRI and CT revealed 6 stages of stress reactions instead of 4 as in Hollenberg’s staging with MRI only. In the 3 earliest stages, of these 6, rest from physical activity for 3 months can heal the stress reaction.
