Key result
Children with habitual snoring and mild sleep-disordered breathing exhibited a significant reduction in parasympathetic tone during all sleep stages, including decreased NN50 (p=0.0003) and total power (p<0.05), compared to healthy controls.
Why the study?
Cardiovascular effects have been observed in children with mild sleep disordered breathing who do not meet criteria for obstructive sleep apnea, prompting investigation into autonomic nervous system changes.
Does chronic snoring with mild sleep disordered breathing alter heart rate variability during sleep in children?

Does chronic snoring with mild sleep disordered breathing alter heart rate variability during sleep in children?
p-value: p=0.0003
Children with habitual snoring and mild sleep disordered breathing exhibit significant reductions in parasympathetic tone during sleep, which may indicate early autonomic impairment and potential future cardiovascular risk.
No takes yet. Share an insight, caveat, or question.
May indicate early autonomic impairment in snoring children; leaves open links to later cardiovascular risk and need for prospective trials.
Lopes et al. (2019) conducted a case-control in Habitual snoring and mild sleep-disordered breathing (n=20). Habitual snoring and mild sleep-disordered breathing vs. Healthy matched controls was evaluated on Heart rate variability (NN50) across all sleep stages (p=0.0003). Children with habitual snoring and mild sleep-disordered breathing exhibited a significant reduction in parasympathetic tone during all sleep stages, including decreased NN50 (p=0.0003) and total power (p<0.05), compared to healthy controls.
