To examine differences in MRI-derived specific fat depots, cardiometabolic risk factors, and HOMA-IR between active and passive school commuters in children, separately for commuting to and from school.
Approach:
Study Design: Cross-sectional analysis using baseline data from the EFIGRO and MICROKID projects.
Participants: 174 children aged 8–14 years with valid data for commuting mode, MRI-derived fat depots, and cardiometabolic outcomes were included.
Measurements: Children's commuting modes were assessed via a validated questionnaire, classifying them as active or passive based on their main mode of commuting.
Key Findings:
Active commuting to school is associated with differences in fat distribution and cardiometabolic risk indicators compared to passive commuting.
Specific fat depots such as VAT, ASAT, IMAAT, and hepatic fat were analyzed in relation to commuting modes.
Interpretation:
The findings suggest that commuting behaviors may influence fat distribution and metabolic health in children, emphasizing the need for further research in this area.
Limitations:
The study is cross-sectional, limiting causal inferences.
Self-reported commuting modes may introduce bias.
Conclusion:
Understanding the impact of active commuting on fat distribution and cardiometabolic risk can inform public health strategies aimed at improving child health.
