Childhood snoring not associated with cardiovascular risk factors short-term

The aim of this study by researchers from Australia was to study the association between childhood snoring and cardiovascular risk factors. It consisted of a cross-sectional analyses of a population-based birth cohort, who had been participants in a randomised controlled trial of interventions to prevent asthma and who were assessed at age 8 years. The presence and frequency of snoring were assessed by parent- completed questionnaire.

Of 409 children whose snoring status was assessed at age 8 years, 321 had lipid and 386 had arterial structure and function measurements. Snoring was not independently associated with blood pressure, carotid artery intima media thickness or measures of arterial stiffness. Increasing snoring frequency was independently associated with lower high-density lipoprotein cholesterol (-0.032 g/dL per step), although the difference in high-density lipoprotein between snorers and non- snorers was not significant. An association of snoring frequency with brachial pulse wave velocity differed according to body mass index and was the reverse of that expected.

The researchers concluded: "Parentally reported snoring was not independently associated with adverse measurements of metabolic markers, vascular structure or function in 8-year- old children. Parental reports of snoring may be below the treatment threshold without additional diagnosis via sleep studies."

Yes, these may not be the children with obstructive sleep apnoea, so parent reporting may not be sufficient.
