Insights
Childhood physical fitness is strongly influenced by body mass index (BMI) and physical activity. Diet and psychosocial factors also play a role, offering targets for health initiatives.
Area of Science:
- Pediatric Health
- Exercise Science
- Public Health
Background:
- Physical fitness in childhood is crucial for long-term health.
- Understanding determinants of physical fitness is key for targeted interventions.
- European children's fitness levels and their influencing factors require comprehensive analysis.
Purpose of the Study:
- To investigate cross-sectional and longitudinal determinants of physical fitness in European children aged 6-11 years.
- To identify key child characteristics, lifestyle factors, and parental influences on physical fitness.
- To explore how these determinants vary by sex and specific fitness components.
Main Methods:
- Utilized data from 4903 European children (50.6% girls).
- Measured physical fitness encompassing cardio-respiratory, muscular strength, flexibility, balance, and speed.
- Employed multivariate and mixed linear regression models to analyze determinants.
Main Results:
- Childhood body mass index (BMI) and physical activity were significant, independent determinants of physical fitness.
- Low maternal BMI, high psychosocial well-being, and fruit/vegetable intake showed small protective effects.
- Longitudinal data emphasized child's BMI as a key fitness determinant, irrespective of physical activity levels.
Conclusions:
- Childhood BMI, physical activity, diet, and psychosocial factors are modifiable targets for enhancing physical fitness.
- Policy interventions should integrate these factors systematically to improve children's fitness.
- Targeted strategies focusing on BMI and lifestyle are essential for promoting pediatric physical fitness.
Objectives:
This study was designed to explore the determinants of physical fitness in European children aged 6-11 years, cross-sectionally and longitudinally.
Methods:
There were sufficient data on 4903 children (50.6 % girls) on measured physical fitness (cardio-respiratory, muscular strength, flexibility, balance, and speed) and possible determinants related to child characteristics, child lifestyle and parental factors. Multivariate and mixed linear regression models were conducted.
Results:
Age, sex, children's BMI and physical activity were independent and strong determinants of children's fitness. Significant but small effects were found for low maternal BMI, high psychosocial well-being and fruit and vegetable intake as protective determinants. Sleep duration, breakfast intake, parental age and education and paternal BMI did not have a consistently significant effect on physical fitness. The role of determinants depended on children's sex and the specific PF component. Longitudinal analyses especially highlighted the importance of child's BMI as physical fitness determinant, independent of physical activity.
Conclusions:
BMI together with physical activity, diet and psychosocial factors are modifiable targets to enhance physical fitness. This calls for policy approaches that combine these factors in a systematic way.
