objective: to estimate the prevalence of obstructive sleep apnea syndrome (osas) in children and adolescents with sickle cell anemia (sca); to investigate the possible correlation between mean annual hemoglobin level and total sleep time with spo2 1 was considered indicative of a diagnosis of osas. results: the prevalence of osas was 10.6%. we found a negative correlation between mean annual hemoglobin level and total sleep time with spo2 %26lt; 90% (r = 米0.343; p = 0.002), as well as between mean annual hemoglobin level and total sleep time with spo2 %26lt; 80% (r = 米0.270; p = 0.016). there was no association between ahi and painful crisis. conclusions: the prevalence of osas in this population was high (10.6%). therefore, it is important to identify signs of osas as soon as possible and to determine the mean annual hemoglobin level because of the inverse correlation between that level and the total sleep time with spo2 %26lt; 90% or %26lt; 80%.
