Physical activity, body composition and physical self esteem among children and adolescents
The increasing prevalence of overweight and obesity poses a global health
problem. Special concern is focused on overweight during youth since it
may cause negative impact on health both during childhood, adolescence
and later life. Physical activity is a key component in preventing
overweight and associated with major health benefits and therefore
crucial in youth health. An important personal factor for being
physically active is the individual perceived physical self-esteem.
Aim The aims of this thesis were to measure physical activity level by
means of daily pedometer steps, body composition, expressed as body mass
index (BMI) and Bioelectrical Impedance as percent body fat, and
individual perceived physical self-esteem. It was also, to test for
reliability and validity the Swedish translation of Children and Youth
Physical SelfPerception Profile (CY-PSPP). Further, to compare activity
and BMI levels between three countries and establish BMI referenced
pedometer determined cut points. An additional aim was to evaluate
eventual predictors for a healthy lifestyle i.e. highly physically
active, normal weighted and a high physical self-esteem in a follow-up
group (FUG).
Methods During autumn 2000 physical activity level (daily mean steps) was
assessed in 892 school children aged 7-14 years in south-eastem Sweden,
additionally BMI was calculated and in 501 of these children physical
self-esteem was also assessed. Using the same protocol, data was gathered
in United States from 711 children and in Australia from 593 children. In
Sweden during autumn 2003, a total of 375 adolescents aged 15-18 years
were assessed using the same methodology and together with that, percent
body fat was measured. Ninety-three of these adolescents, (46 girls),
were also measured in 2000 (FUG).
Results The results provided baseline information useful as reference
data on levels of physical activity, BMI (age 7-18) perceived physical
self-esteem (age 10-17) and percent body fat (age 15-18). A drop in
physical activity was seen in boys during early adolescents. Physical
activity (accumulating daily steps) correlated, in most age groups poor
to fair negatively to BMI and poor to fair to physical self-esteem. In
boys, there was a poor negative, and in girls, a fair negative
correlation between physical self-esteem and BMI. BMI criterionreferenced
cut points indicated, for each sex and age group, the optimal median cut
point for steps per day for 6-12 year olds to be 12 000 steps per day for
girls and 15 000 steps per day for boys. In the FUG the strongest
predictor to be highly physically active, maintain a normal BMI and a
high physical self-esteem three years later, was for girls increased
physical self-esteem and for boys a decreased BMI.
Conclusion Instruments used herein, pedometers and the Swedish
translation of the CYPSPP, were useful to measure and classify levels of
physical activity and perceived physical self-esteem in children and
adolescents. With these instruments it was possible to identify
individuals "at risk" for physical inactivity and low physical
self-esteem. Based on pedometer steps per day, understandable
recommendations could be given to professionals in health care and
education, parents, children and adolescents and thereby support actions
formed to influence healthy habits
Secular trends of pedometer-determined physical activity in Swedish school children
Aim: To explore the secular trends (time change) of pedometer-determined physical activity (steps per day) in Swedish schoolchildren 7\u969 years of age from 2000 to 2006. It was an additional aim to examine the secular trends in body mass index.
Methods: The study was analyzed between two cross-sectional cohorts on children 7\u969 years of age carried out in October 2000 (336 children, 153 girls) and March/April 2006 (168 children, 83 girls) in the same five schools in south eastern Sweden, using identical procedures at the two occasions. Data of mean steps per day were collected during four consecutive weekdays (sealed pedometer Yamax SW-200 Tokyo, Japan) and in addition height and weight were measured.
Results: Physical activity (mean steps per day) was significantly higher in 2006 than in 2000 among girls (13788 vs. 15141 steps per day) and boys (15991 vs. 16973 steps per day). The share of girls and boys to meet the preliminary weight control recommendations of 12000 and 15000 steps per day respectively was higher in 2006 than in 2000: 90% versus 75% (girls) and 67% versus 60% (boys).
Conclusion: The level of physical activity (steps per day) during school weekdays was higher in 2006 than in 2000. Enhanced focus on physical activity in society and at school might have influenced the result
Att studera förskolebarns fysiska aktivitet
Förskolebarns fysiska aktivitet har en viktig hÀlsopromotiv effekt mot flera av vÄra vÀlfÀrdssjukdomar. DÀrför Àr det av yttersta vikt att förskolemiljön stimulerar förskolebarnen till en hÀlsosam fysisk aktivitet. I Kidscape projektet studerade vi förskolebarns fysiska aktivitet under vistelsen pÄ förskolan. Syftet var att hitta faktorer i skolgÄrdens utemiljö som pÄverkar barnens aktivitetsmönster. Aktivitetsmönstret studerades med bÄde subjektiva (CARS och kvalitativ observation) och objektiva metoder (pedometri och accelerometri). Resultatet visade att förskolebarnens fysiska aktivitet var högre i förskolor med en bra skolgÄrdsmiljö. Slutsats: förskole gÄrdens utformning kan frÀmja en hÀlsosam fysisk aktivitet hos förskolebarn
The study of childrenâs physical activity
Preschool children's physical activity has an important health promoter against several of the lifestyle diseases. Therefore it is important that the preschool environment encourages preschool children to a healthy physical activity. In the Kidscape project we studied preschool children's physical activity during their stay at the preschool. The aim was to identify factors in the outdoor environment that influence children's activity patterns. Activation patterns were studied with both subjective methods (CARS and qualitative observation) and objective methods (pedometri and accelerometry). The results showed that preschool children's physical activity was higher in preschools with a good schoolyard environment. Conclusion: preschool outdoor environment can promote a healthy physical activity in preschool children
