Physical fitness of 9 year olds in England : related factors.
Study objective-To examine the influence of social factors, passive smoking, and other parental health related factors, as well as anthropometric and other measurements on children's cardiorespiratory fitness.
Design-This was a cross sectional study.
Setting-The analysis was based on 22 health areas in England.
Participants-The subjects were 299 boys and 282 girls aged 8 to 9 years.
Parents did not give positive consent for 15% of the eligible sample.
A further 25% of the eligible sample did not participate because the cycle-ergometer broke down, study time was insufficient, or they were excluded from the analysis because they were from ethnic minority groups or had missing data on one continuous variable.
The association between children's fitness and biological and social factors was analysed in two stages.
In the logistic analysis, shorter children, children with higher blood pressure, and boys with a larger sibship size had poorer fitness.
In the multiple regression analysis, only height (p<0.001) was positively associated, and the sum of skinfold thicknesses at four sites (p=0.001) was negatively associated with fitness in both sexes.
In girls, a positive association was found with pre-exercise peak expiratory flow rate (p<0.05), and there were negative associations with systolic blood pressure (p<0.05) and family history of heart attack (p<0.05).
In boys an association was found with skinfold distribution and fitness (p<0.05), so that children with relatively less bo.
