ABSTRACT
Moderately preterm birth seems to be an evolutional risk condition at cognitive, behavioural and socio-relational levels. The study is aimed to investigate the likely occurrence of precursors of Attention Deficit Hyperactivity Disorder (ADHD) in moderately preterm children at preschool age. The research involved an experimental group made up of 50 moderately preterm children (mean: 34.6 weeks' gestational age, standard deviation [SD]: 2) without any medical and neurologic neonatal complications and low birth weight (mean:2100g., SD: 350g.) and a check group of 50 full term born children. Parents and teachers of children were administered specific questionnaires to detect ADHD. The outcomes show a risk of ADHD highlighting statically significant differences related to gender [F(2, 99) = 2.99, p = .04], birth [F(2, 99) = 9.6, p = .03] and interaction [F(2, 99) = 2.2, p = .01]. The moderately preterm children showed deficit in self-regulation [F(2, 99) = 1.14, p = .04] and attention deficit in daily life both in family [F(2, 99) = 7.8, p = .04] and school contexts [F(1, 99) = 3.3, p = .04]. The outcomes hint assessment paths aimed to monitor the aspects of cognitive, motor, behavioural development of moderately preterm children recognised as signs of problematic functioning profiles. Therefore, specific training will have been designed since preschool age in order to control the ADHD risk factors.
ABSTRACT
The low attention and hyperactivity are major morbidities associated with very and moderately preterm birth. The study has been aimed at investigating the likely occurrence of early precursors of Attention Deficit and Hyperactivity Disorder (ADHD) in very and moderately preterm children at preschool age. The involved children were: 25 very preterm children (M=29.4 weeks of gestational age, SD=2), with low birth weight (M=1200 g, SD=250 g); 35 moderately preterm children (M=34.6 weeks of gestational age, SD=1) with low birth weight (M=2100 g, SD=250 g); 60 healthy full-term children as the control group. Parents of children have been administered specific questionnaires to detect low attention and hyperactivity of their children at home. The data have shown the risk of precursors of ADHD, highlighting statistically significant birth-related differences in both hyperactivity/impulsivity [F(2,119)=3.5, P=0.03, η(2)=0.06] and inattention [F(2,119)=2.4, P=0.04, η(2)=0.04], where very preterm children have got higher scores in these two dimensions compared with full-term and moderately preterm children. The very preterm children have got higher scores of impulsivity and inattention than the full-term children (Tukey'HSD - Honestly Significant Difference; P<0.001).
ABSTRACT
BACKGROUND: The study deals with the characteristics of temperament of preterm infants during their preschool age in order to not only investigate likely "difficult or problematic profiles", guided by impairments driven by their preterm birth, but also to provide guidelines for the activation of interventions of prevention, functional to improve the quality of preterm infant's life. METHODS: The study involved a group of 105 children where 50 preterm children at the average age of 5 years and 2 months, enrolled in preschools of Palermo. The research planned the child reference teachers to be administered a specific questionnaire, the QUIT, made up of 60 items investigating six specific typical dimensions of temperament (Motor control activity - related to the ability of practicing motor control activity; Attention - related to the ability of guiding and keeping the focus of attention on a certain stimulus; Inhibition to novelty - regarding with emotional reactivity in front of environmental stimuli; Social orientation - meant in terms of attention and interest towards social stimuli; Positive and negative emotionality - regarding the tendency to mainly express positive or negative emotions. RESULTS: The results show in general how preschool-aged preterm infants, identified by such a study, compared with full-term children, are characterized by "normal" temperament based on a strong inclination and orientation in mainly expressing positive feelings. Yet, an impairment of the areas most relating to attention and motor control activity seems to emerge. CONCLUSIONS: The data suggest specific interventions for preterm infant development and their reference systems and, at the same time, can guide paediatrician and neonatologist dealing with preterm infants, in focalizing and monitoring, even since health status assessments, specific areas of development that, since preschool age, can highlight the presence of real forerunners of maladjustments and likely configurations of cognitive, emotional or behaviour disadaptive functioning.
