Compared to full term , premature infants exhibit significant differences in sleep structure , which mainly include differences in electroencephalographic spectral values , in total sleep time and in arousal threshold .

Conclusions The alterations in sleep patterns are an outcome of prematurity ( immaturity of nervous system ) as well as of postnatal factors and comorbidities .

Prevalence and risk factors for sleep-disordered breathing in 8- to 11-year-old children: association with race and prematurity.
OBJECTIVES To evaluate the extent to which sleep-disordered breathing ( SDB ) varies with putative demographic and medical risk factors and to estimate the prevalence of undiagnosed SDB . STUDY DESIGN Prospect i ve , cross-sectional study in a population -based cohort of 850 children ( 41 % black , 46 % preterm ) , 8 to 11 years of age . Participants ' caretakers completed question naires about health and sleep . Children underwent overnight in-home cardiorespiratory recordings of airflow , respiratory effort , oximetry , and electrocardiography . SDB was identified by respiratory disturbance indices commonly applied in clinical practice . Risk factors were estimated by logistic regression . Prevalence was derived from cohort-specific estimates with birth weights from US live births data . RESULTS Using the most inclusive definition , SDB was detected in 40 ( 4.7 % ) participants , with prevalence varying widely across population subsets . Depending on the definition used , SDB was 4 to 6 times more likely in black children compared with white children and almost 3 to 5 times more likely in former preterm compared with term children . The estimated population prevalence of SDB was 2.2 % ( 95 % CI , 1.2 % , 3.2 % ) . CONCLUSIONS SDB is a relatively common condition in 8- to 11-year-old children . Potentially vulnerable subgroups , black children , and former preterm infants , are at increased risk
