“…Behavioral results with the APIB confirm previous findings (Als, Duffy, & McAnulty, 1988a, 1988bFerrari et al, 1983;Sell et al, 1980) that fullterm and preterm infants differ even when selected to be medi- cally healthy and studied at comparable age points after expected date of confinement.…”

“…Moreover, Ferrari, Grosoli, Fontana, and Cavazzuti (1983), using the NBAS, confirm this finding for behavioral functioning, as do Sell, Luick, Poisson, and Hill (1980) using a prepublication version of the Assessment of Preterm In-fant Behavior (APIB) (Als, Lester, Tronick, & Brazelton, 1982b).…”

We investigated the effects of gestational age at birth on behavioral and electrophysiological measures of 135 medically healthy infants, studied at 42 weeks postconception, and stratified into 3 groups--early-born preterms, 26-32 weeks (n = 55); middle-group preterms, 33-37 weeks (n = 43); and fullterms, 38-41 weeks (n = 37). Subjects were studied behaviorally with the Assessment of Preterm Infants' Behavior (APIB) and electrophysiologically with brain electrical activity mapping (BEAM). Fullterms showed significantly better behavioral function than both preterm groups. Less difference was found between the preterm groups. EEG spectral and photic evoked response were of significantly less amplitude for the preterms than the fullterms. Path analysis showed gestational age effects on behavioral (3 of 6) and electrophysiological (13 of 17) variables due to postnatal complications. We conclude that some differences attributable to gestational age at birth are explained by the cumulative effect of minor but unavoidable complications associated with premature birth. We speculate that remaining effects may result from developmentally inappropriate sensorimotor stimulation consequent to the premature experience of an extrauterine environment.

“…Barnard suggests that the developmental outcome of infants is the product of the interaction among the characteristics of infants, the adaptive styles of mothers, and the qualities of the environment, such as family income, supportive family relationships, and the stimulation available in the home. Compromised developmental progress of preterm infants is associated with difficult patterns of mother-infant interaction that are aggravated by stressful conditions (Bakeman & Brown, 1980;visual and auditory stimuli (Gorslu, Davis& & Brazeiton, 1979;Sell, Luick, Poisson, & Hill, 1980;Telzrow, Kang, Mitchell, Ashworth, & Barnard, 1982). They have unorganized periods of sleep and wakefulness.…”

This study was designed as a multi-site field experiment to test the efficacy of hospital and home visit interventions to improve interaction between mothers and preterm infants. Hospital intervention consisted of State Modulation (SM) treatment, which focused on teaching mothers to read the behavioral cues and modulate the states of consciousness of preterm infants during feedings. Home visit intervention was a field-tested program, Nursing Systems for Effective Parenting-Preterm (NSTEP-P), implemented during the first five months after the infant's hospital discharge. A hospital program on car seats (CS) and standard public health nursing home visits (PHN) served as comparison treatments. The sample consisted of 327 mothers and their preterm infants who were less than 36 weeks of gestational age at hospital discharge. Mothers were randomly assigned to intervention groups on the basis of their education. High education (HE) was > or = 13 years of education, while low education (LE) was < or = 12 years of education. HE mothers were only assigned to hospital programs, while LE mothers were assigned to combinations of hospital and home visit programs. Evaluations were conducted at 40 weeks conceptual age (expected date of birth), at 46 weeks conceptual age (1.5-months-corrected age), and 60 weeks conceptual age (5-months-corrected age). Comparisons were made within each educational group. For HE groups, SM infants gave significantly more clear cues during observations of feeding interactions at 1.5-months-corrected age and teaching interactions at 5-months-corrected age than infants in the CS group. During the teaching interaction, well-educated SM mothers provided significantly more social-emotional and cognitive stimulation than CS mothers. For LE groups, infants in the SM group combined with either PHN or NSTEP-P exhibited significantly more responsive behavior during feeding observations than those infants in the CS/PHN group at 1.5-months-corrected age. LE mothers in the SM/NSTEP-P group demonstrated more sensitivity and more stimulation during teaching interactions at 5-months-corrected age than mothers in the SM/PHN or CS/PHN groups. Findings suggest that State Modulation treatment is effective in influencing positive social interaction of infants regardless of the level of maternal education. State modulation treatment combined with NSTEP-P is most effective in improving the social interaction between preterm infants and mothers with limited formal education. Such treatment-specific programs suggest avenues for providing cost-effective care that complements the changing transactional needs of mothers and preterm infants.

“…In the 1980s the question 'how small is too small?' is still unsolved (Sell et al 1980). The health state of the surviving child, socio-economic factors and ethical aspects have to be taken into consideration.…”

SUMMARY In a population of extremely low‐birthweight (ELBW) infants with birthweights from 500 to 900g, born at 24 to 30 weeks gestation, neurobehavioural development at term was evaluated with the Brazelton Neonatal Behaviour Assessment Scale (BNBAS) and a standardized neurological examination. Compared with a control group of fullterm infants, no significant group differences were found for 19 of 27 BNBAS items; in seven other items they scored significantly lower and in one item they scored significantly higher. The BNBAS and the neurological examination showed abnormal responses in most ELBW infants with intracranial haemorrhage, especially those with grades III or IV. In spite of these differences the ELBW infants at term had a wide behavioural repertoire, with repeated, but short, periods of alertness and high performance. Parental awareness of the fluctuating state of ELBW infants at term is important for adequate parent‐infant interactions. RÉSUMÉ Développement neuro‐comportemental à terme chez les nourrissons d'extrêmement faible poids de naissance Dans une population d'extrême nt faible poids de naissance (PNEF) avec poids de naissance allant de 500 à 900 g. née entre 24 et 30 semaines de gestation, le développement neuro‐comportemental à terme a été avec les scores d'appréciation de comportement néonatal de Brazelton (BNBAS) et un examen neurologique standardisé. Par comparaison avec un groupe contrôle de nourrissons nés à terme, aucune différence significative n'a été noté pour 19 des 27 items BNBAS; pour sept autres items le score était significativement plus bas et pour un item le score était significativement plus élevé. Le BNBAS et l'examen neurologique donnaient des réponses anormales chez la plupart des nourrissons PNEF avec hémorragie intra‐cranienne, spécialement pour les niveaux trois ou quatre. En dépit de ces différences les nourrissons PNEF avaient un large répertoire comportemental, avec des périodes répétées mais courtes de vigilance et de performances élevées. La perception parentale de la fluctuation de vigilance des nourrissons PNEF à terme est importante pour la mise en place d'interactions parents‐nourrissons adéquates. ZUSAMMENFASSUNG Entwicklungsneurologie am Termin bei Kindern mit extrem niedrigem Geburtsgewicht Bei einer Gruppe von Kindern mit extrem niedrigem Geburtsgewicht (ELBW) von 500 bis 900g und einem Gestationsalter von 24 bis 30 Wochen wurde der entwicklungsneurologische Status am Termin anhand des Brazelton Neonatal Behaviour Assessment Score (BNBAS) und einer standardisierten neurologischen Untersuchung beurteilt. Im Vergleich zu einer Kontrollgruppe reifgeborener Kinder wurden für 19 von 27 BNBAS Aufgaben keine Gruppenunterschiede gefunden; bei sieben Aufgaben hatten sie signifikant niedrigere Scores und bei einer signifikant höhere. Der BNBAS und die neurologische Untersuchung ergaben bei den meisten ELBW Kindern mit intracranieller Blutung, besonders bei denen mit Grad III und IV, abnorme Befunde. Trotz dieser Unterschiede hatten die ELBW Kinder am Termin ein breit...
