Why the study?
Does obesity alter cardiac autonomic modulation (heart rate variability) in children aged 8 to 12 years compared to eutrophic children?
Population
121 children (57 male, 64 female) aged 8 to 12 years
Comparison

May indicate early autonomic impairment in obese children; leaves open causality and reversibility in longitudinal studies.
Does obesity alter cardiac autonomic modulation (heart rate variability) in children aged 8 to 12 years compared to eutrophic children?
Obese children exhibit reduced sympathetic and parasympathetic activity as measured by heart rate variability, highlighting early autonomic dysfunction.
Vanderlei et al. (2010) studied this question.
