Sleep-disordered breathing is associated with higher carboxymethyllysine level in elderly women but not elderly men in the cardiovascular health study

ContextCarboxymethyl-lysine (CML) results from oxidative stress and has been linked to cardiovascular disease.ObjectiveThe objective of this study is to investigate the association between sleep-disordered breathing (SDB) - a source of oxidative stress - and CML.Materials and methodsAbout 1002 participants in the Cardiovascular Health Study (CHS) were studied.ResultsWomen with SDB had significantly higher CML concentration compared with those without SDB (OR = 1.63, 95%CI = 1.03-2.58, p = 0.04). The association was not significant among men.DiscussionSDB was associated with CML concentration among elderly women but not men in the Cardiovascular Health Study.ConclusionAccumulation of CML may be an adverse health consequence of SDB
