Elevated fibrinogen level is a predictor of cardiovascular disease in adults, and it is associated with sleep-disordered breathing. Levels of fibrinogen in adults are affected by other co-existing cardiovascular risk factors, which are not usually present in children.
To investigate the association between fibrinogen and sleep-disordered breathing, a case-control study was carried out in children with and without habitual snoring. All snoring children underwent polysomnography.
Morning fibrinogen values in 30 children with snoring and an apnoea-hypopnoea index (AHI) 5 episodes·h1 (median (interquartile range) 318 mg·dL1 (290374)) were similar to values in 61 children with snoring and an AHI <5 episodes·h1 (307 (269346)). Both groups had higher fibrinogen values than those in 23 controls without snoring (271 mg·dL1 (244294)). There was no correlation between fibrinogen values and AHI, respiratory movement/arousal index or haemoglobin desaturation index.
In conclusion, fibrinogen values are higher in children with snoring than in controls, but there is no association between these values and polysomnography indices.
