AimHomozygous sickle cell anaemia (SCA; HbSS) is associated with neurological compromise and attention difficulties. Previous work has shown tentative links between executive dysfunction and daytime oxygen desaturation in SCA. Previous work has not however examined the effects of nocturnal oxygen saturation on attention, nor has it considered whether any relationship is confounded by the effects of socio-economic status (SES) or age.MethodsThirteen children (8-12 years, 6 Female) and twentytwo adolescents (13-18 years, 11 Female) with SCA enrolled on the Prevention of Morbidity in Sickle Cell Disease Phase 2 randomised controlled trial of auto-adjusting continuous positive airways pressure underwent cognitive assessment at baseline, which included the Conners' Continuous Performance Test (CPT). Overnight oximetry was conducted at home within two weeks of assessment. Multiple deprivation indices (MDI) were derived from postcodes.ResultsIn adolescents, after correcting for the effects of MDI, correlations were found between time spent with oxygen saturation
