Abstract
Background: The prevalence of overweight among children has increased in the past years. Physical activity has a major impact on the energy balance and possibly on children’s BMI as well. Physical education (PE) in primary schools could contribute to the fight against overweight among young children. In this study, the association between the frequency of PE and the BMI of 5-year olds, has been explored. Methods: Data of children of the GECKO Drenthe cohort (n = 1189) has been used. Height and weight are measured at an age of 3 years and 9 months and at 5 years, and their BMI and BMI z-scores were calculated. Through questionnaires, information about the frequency of PE, ethnicity, parents’ BMI en parents’ educational level was obtained. A subgroup of the children (n = 676) wore an accelerometer (Actigraph GT3X) for 4 days to measure the intensity of their physical activity in MVPA (moderate to vigorous physical activity). Results: At age 5, 14,4% of the children was overweight or obese. 53,6% of the children receives PE 2x a week. The frequency of PE was not associated with the BMI z-scores of the children (2x vs. 0-1x gym: β 0,031 [95% BI -0,077; 0,140] en 3-5x vs. 0-1x gym: β 0,079 [-0,063;0,221]). The frequency of PE was not associated with changes in BMI (2x vs. 0-1x gym: β 0,008 [-0,077;0,094] en 3-5x vs. 0-1x gym: β 0,104 [-0,011; 0,219]). Children who got PE more often were physically not more active (2x vs. 0-1x gym: β 0,168 [-0,385; 0,721] en 3-5x vs. 0-1x gym: β 0,267 [-0,441; 0,974]). Physical activity was not associated with BMI changes (β 0,314; p 0,183). Conclusion: No association was found between the frequency of PE and children’s BMI. It is possible that other factors also have an important effect on children’s BMI. However, these results don’t exclude the possibility that PE in primary schools could still play a big role in the fight against overweight among children.
