“…PI present sleep with polyphasic pattern that are classified into three stages: active, quiet and indeterminate sleep (3,7,(9)(10) . The different stages of sleep are essential for the homeostasis of premature infants, because they establish relations with important physiological and neurological activities (3,9) . In the quiet sleep, decreased basal metabolic rate occurs, which promotes replenishment of energy reserves as well as promote cellular repair, in the active sleep brain activation occurs, which is essential for the structural maturation of the central nervous system (10)(11) .…”

Objective:To compare the total sleep time of premature infant in the presence or absence of reducing sensory and environmental stimuli in the neonatal unit. Method: Longitudinal study in a Neonatal Intermediate Care Unit of a public hospital in Sao Paulo. The sample consisted of 13 premature infants. We used polysomnograph and unstructured observation for data collection. We analyzed 240 and 1200 minutes corresponding to the periods of the presence and absence of environmental management, respectively. Data were compared in proportion to the total sleep time in the two moments proposed by the study. Results: The total sleep time in periods without environmental management was on average 696.4 (± 112.1) minutes and with management 168.5 (± 27.9) minutes, proportionally premature infant slept an average of 70.2% during periods with no intervention and 58.0% without management (p=0.002). Conclusion: Reducing stimulation and handling of premature infant environment periods was effective to provide greater total sleep time. DESCRIPTORS INTRODUCTIONThe estimate of premature births in Brazil is about 9.8% of the 2,913.160 births registered in 2011 (1) . Due to prematurity, the proportion of premature infants (PI) may require hospitalization in a neonatal unit, which is commonly characterized as in environment that has high sensory stimuli overload for the newborn, additionally, there is a need for frequent management for invasive and painful procedures (2)(3)(4)(5) . The characteristics of the neonatal unit environment and care provided to premature infants according to the institutional routines can reduce the total sleep time leading them to consequent deprivation, which can be constituted in morbidity factor, especially when the gestational age is low and the length of hospital stay is long (2,4,6) . Many studies show that sleep deprivation of premature infants in the neonatal unit can lead to worsening of clinical status and delay hospital discharge, besides that, it could trigger behavioral disorders in adulthood (4,(7)(8) . PI present sleep with polyphasic pattern that are classified into three stages: active, quiet and indeterminate sleep (3,7,(9)(10) . The different stages of sleep are essential for the homeostasis of premature infants, because they establish relations with important physiological and neurological activities (3,9) . In the quiet sleep, decreased basal metabolic rate occurs, which promotes replenishment of energy reserves as well as promote cellular repair, in the active sleep brain activation occurs, which is essential for the structural maturation of the central nervous system (10)(11) . It is noteworthy that the indeterminate sleep cannot be considered as quiet or active, it is characterized as the transition between these two types of sleep patterns (12) . Mitigating possible harmful effects of care provided to hospitalized newborns is one of the actions that should be prioritized by professionals working towards recovery (13) . In this context, the developmental care aims at reduc...

“…[1] Thus, the relationship between the two is vital, as the control of sleepwake cycles are regulated by the CNS. [2] At present, we do not have sufficient data to conclude that a causal relationship exists between infant's sleep and development. The EEG recording itself is quite different in children than adults because the brain, meninges, skull, scalp, head size as well as child's behavior, and ability to cooperate all changes over time.…”

Background: This study is concerned with the changes of electroencephalographic (EEG) from immature neonatal to the development of mature normal EEG pattern with special attention given to the infant's age (0-12 months), growth, and developmental level. Aims and Objectives: The objective is to study serially development of specific EEG patterns in infants, i.e., from birth to 12 months of age. Materials and Methods: This is a longitudinal follow-up study conducted on 50 (27 female and 23 male) healthy, normal, full-term infants delivered vaginally in the Department of Obstetrics and Gynaecology, Netaji Subhash Chandra Bose, Medical College and Hospital, Jabalpur, Madhya Pradesh, starting from the birth to 12 months of age in normal environment in the Department of Physiology EEG-unit for 60 min in 5 different visits, i.e., at birth/0-2 week, 3-month, 6 months, 9 months, and 12 months. Result: This study provides clearly established strong changes in EEG wave pattern and their appearances with increased speed of response, which are most clearly visible from the time of birth, 3-6 months, and at 12 months of age. These marked changes of EEG may be associated with language and other motor milestone development. Conclusion: Sleep characteristics during this period may have predictive value in the assessment of future neurodevelopmental conditions. The study also concluded that the percent of time that infants spend in sleep decreased sharply from 3 to 6 months, but the sleep cycle becomes more defined. The duration of infant's sleep did not change significantly across the 1 st year, but the percent of time spent in active sleep is markedly decreased, i.e., ≤25%, and the sleep progresses toward maturity which is confirmed by the establishment of continuity, symmetrical synchronous EEG pattern, and the disappearance of neonatal trace alternant, along with the focusing on measurement of weight and head circumference.

“…Clinical studies with infants younger than 12 months showed associations between sleep duration, number of awakenings and sleep morphology in EEG with concurrent and later scores in standardised developmental batteries (Becker & Thoman, 1981;Freudigman & Thoman, 1993;Scher, Steppe, & Banks, 1996; for a review see Ednick et al, 2009). Longitudinal relationships across longer periods of development have also been found for toddlers (Dearing, McCartney, Marshall, & Warner, 2001) and school-aged children (Buckhalt, El-Sheikh, & Keller, 2007;Buckhalt, El-Sheikh, Keller, & Kelly, 2009).…”

Learning and Individual Differences

Infant sleep undergoes significant re-organization throughout the first 12 months of life, with sleep quality having significant consequences for infant learning and cognitive development. While there has been great interest in the neural basis and developmental trajectories of infant sleep in general, relatively little is known about individual differences in infant sleep and the socio-economic and cultural sources of that variability. We investigated this using questionnaire sleep data in a large, unique multi-ethnic sample of 6–7 month-olds (n = 174), with families from South Asian ethnic groups in the UK (Indian, Pakistani and Bangladeshi) being especially well represented. Consistent with previous data from less variable samples, no effects of SES on sleep latency or nocturnal sleep duration emerged. However, perinatal risk factors and ethnic differences did predict daytime sleep, sleep fragmentation and sleep-onset time. While these results should be interpreted with caution due to several limitations, they likely demonstrate that even when socio-economic status and ethnicity are much less confounded than in previous studies, they have a surprisingly limited impact on individual differences in sleep patterns in young infants
