Aim: To compare attention skills of children with a very low birth weight (VLBW) with children with a normal birth weight (NBW) when entering primary school, and explore the association of attention skills with school career 2 years later., Methods: Participants were 151 children with VLBW and 41 with NBW. Attention was assessed at 3 years and 8 months of corrected age (CA) and school career at 5½ years of CA. Children performed two tests, parents completed three questionnaires, and an assessor systematically observed children's attention., Results: Children with VLBW had significantly lower mean scores on five of the six measures. Significantly more children with VLBW had scores in the clinical range on the Child Behavior Checklist completed by the parents (13% versus 0%) and scores representing dysfunction on assessor observations (19% versus 2%). At 5½ years of age, 36% of the children with VLBW followed special education or had grade retention. Dysfunctional attention as observed by the assessor was most strongly associated with need for learning support at 5½ years of age., Conclusions: At preschool age, children with VLBW have attention difficulties. Attentive behavior at preschool age is a predictor of school career 2 years later.

Aim: To elucidate the relation between motor impairment and other developmental deficits in very preterm-born children without disabling cerebral palsy and term-born comparison children at 5 years of (corrected) age., Method: In a prospective cohort study, 165 children (81 very preterm-born and 84 term-born)were assessed with the Movement Assessment Battery for Children - 2nd edition, Touwen’s neurological examination, the Wechsler Preschool and Primary Scale of Intelligence, processing speed and visuomotor coordination tasks of the Amsterdam Neuropsychological Tasks, and the Strengths and Difficulties Questionnaire., Results: Motor impairment (≤15th centile) occurred in 32% of the very preterm-born children compared with 11% of their term-born peers (p=0.001). Of the very preterm-born children with motor impairment, 58% had complex minor neurological dysfunctions, 54% had low IQ, 69% had slow processing speed, 58% had visuomotor coordination problems, and 27%, 50%,and 46% had conduct, emotional, and hyperactivity problems respectively. Neurological outcome (odds ratio [OR]=41.7, 95% confidence intervals [CI] 7.5–232.5) and Full-scale IQ(OR=7.3, 95% CI 1.9–27.3) were significantly and independently associated with motor impairment. Processing speed (OR=4.6, 95% CI 1.8–11.6) and attention (OR=3.2, 95% CI1.3–7.9) were additional variables associated with impaired manual dexterity. These four developmental deficits mediated the relation between preterm birth and motor impairment., Interpretation: Complex minor neurological dysfunctions, low IQ, slow processing speed,and hyperactivity/inattention should be taken into account when very preterm-born children are referred for motor impairment.

This study investigated whether multiple developmental difficulties are more frequent in very low birth weight (VLBW) children than in those born full term. The association between multiple developmental difficulties assessed at 3½ years of age and educational provision for the child at 5½ years was also investigated, with 'educational provision' referring to the curriculum, school placement and the level of learning support. There were 143 VLBW children without cerebral palsy (CP) and 41 term-born peers assessed at 3½ years of age. The assessment included 6 measures of development: word comprehension, visual motor integration, visual perception, motor coordination, executive functioning and behaviour. Educational provision was determined at age 5½ years. A mildly abnormal score (score <1 standard deviation) was considered to indicate developmental difficulty. Scores from the six measures of development were analysed to determine the difficulty frequency and the presence of multiple difficulties (>1 difficulty score) in each child. This study showed that at 3½ years of age, the VLBW children had significantly more difficulty with motor coordination than their term-born peers. In addition, 27% of the VLBW children had multiple difficulties compared to 10% in the term-born group. Multiple logistic regression analyses showed that of the difficulties, impaired motor coordination was most strongly associated with the requirement for learning support two years later. Regression analyses showed that having multiple difficulties was significantly associated with the need for learning support (Odds Ratio of 3.4 (95% CI: 1.5-7.8). These results show that the presence of multiple difficulties in a VLBW child of preschool age, can impact the child's educational provision two years later., (Copyright © 2013 Elsevier Ltd.

Background: Infants with very low birth weight (VLBW) are at increased risk for motor deficits, which may be reduced by early intervention programs. For detection of motor deficits and to monitor intervention, different assessment tools are available. It is important to choose tools that are sensitive to evaluate the efficacy of intervention on motor outcome., Objective: The purpose of this study was to compare the Alberta Infant Motor Scale (AIMS) and the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development-Dutch Second Edition (BSID-II-NL) in their ability to evaluate effects of an early intervention, provided by pediatric physical therapists, on motor development in infants with VLBW at 12 months corrected age (CA)., Design: This was a secondary study in which data collected from a randomized controlled trial (RCT) were used., Methods: At 12 months CA, 116 of 176 infants with VLBW participating in an RCT on the effect of the Infant Behavioral Assessment and Intervention Program were assessed with both the AIMS and the PDI. Intervention effects on the AIMS and PDI were compared., Results: Corrected for baseline differences, significant intervention effects were found for AIMS and PDI scores. The highest effect size was for the AIMS subscale sit. A significant reduction of abnormal motor development in the intervention group was found only with the AIMS., Limitations: No Dutch norms are available for the AIMS., Conclusions: The responsiveness of the AIMS to detect intervention effects was better than that of the PDI. Therefore, caution is recommended in monitoring infants with VLBW only with the PDI, and the use of both the AIMS and the Bayley Scales of Infant Development is advised when evaluating intervention effects on motor development at 12 months CA.

This study investigates whether very low birth weight (VLBW) preschoolers experience disability in daily activities and what the risk factors for disability in daily activities are. The Dutch Pediatric Evaluation of Disability Inventory (PEDI-NL) was used to detect disability in daily activities in 143 VLBW children without cerebral palsy (CP) at 44 months of corrected age (CA). Data from the psychomotor-developmental index (PDI) and the mental developmental index (MDI) of the Bayley Scales of Infant Development II (BSID II) at 24 months CA, and data relating to perinatal and socio-economic status were available. Disability in daily activities was found in 27 (19%) VLBW children without CP. High frequencies of disability were found in 19 (13%) children on the mobility domain and in 12 (8%) children on the social functioning domain. The multiple logistic regression analyses showed that low BSID II outcomes (<2 SD) were risk factors for disability in the mobility domain, but not for disability in the social functioning domain. The predictive value of the BSID II outcomes is moderate, 46% of the VLBW children with a low PDI and 44% with a low MDI developed a disability in the mobility domain. This study showed a higher frequency of disability in daily activities in VLBW preschoolers compared to term born peers. Therefore, it is suggested to assess VLBW children's performance of daily activities before they start school., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

Objective: To evaluate the effect of the Infant Behavioral Assessment and Intervention Program (IBAIP) in very low birth weight (VLBW) infants on cognitive, neuromotor, and behavioral development at 5.5 years corrected age (CA)., Study Design: In a randomized controlled trial, 86 VLBW infants received post discharge IBAIP intervention until 6 months CA, and 90 VLBW infants received standard care. At 5.5 years CA, cognitive and motor development, and visual-motor integration were assessed with the Wechsler Preschool and Primary Scale of Intelligence, third Dutch version, the Movement Assessment Battery for Children, second edition, and the Developmental Test of Visual Motor Integration. Neurologic conditions were assessed with the neurologic examination according to Touwen, and behavior with the Strengths and Difficulties Questionnaire., Results: At 5.5 years CA, 69 children in the intervention and 67 children in the control group participated (response rate 77.3%). Verbal and performance IQ-scores<85 occurred significantly less often in the intervention than in the control group (17.9% vs 33.3%, P=.041, and 7.5% vs 21.2%, P=.023, respectively). However, after adjustment for differences, only the OR for performance IQ was significant: 0.24, 95% CI: 0.06-0.95. Adjusted mean scores on Wechsler Preschool and Primary Scale of Intelligence, third version subtasks block design and vocabulary, the Movement Assessment Battery for Children, second edition component aiming and catching, and the Developmental Test of Visual Motor Integration were significantly better in the intervention group. No intervention effect was found on the Strengths and Difficulties Questionnaire., Conclusion: The IBAIP leads, 5 years after the early neurobehavioral intervention, to improvements on performance IQ, ball skills, and visual-motor integration at 5.5 years CA., (Copyright © 2013 Mosby, Inc.

Background: The Infant Behavioral Assessment and Intervention Program (IBAIP©) improved motor function at 24 months, and mental and behavioural development in high risk subgroups of very low birth weight (VLBW) infants., Aim: To determine IBAIP's effects on executive functioning, behaviour and cognition at preschool age., Study Design: Follow-up of a randomised controlled trial (RCT)., Subjects: At 44 months corrected age, all 176 VLBW infants were invited for follow-up. Forty-one term born children were assessed for comparison., Outcome Measures: Visual Attention Task (VAT), Gift delay, Peabody Picture Vocabulary Test III-NL (PPVT), Visual motor integration tests and Miller assessment for preschoolers. Parents completed Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P) and Child Behavior Checklist (CBCL)., Results: At preschool age, 76 (88%) children of the intervention group and 75 (83%) children of the control group participated. There were no significant differences between the intervention and the control group. However, positive interaction effects between intervention and infants with bronchopulmonary dysplasia, infants born at gestational age<28 weeks, and infants of low educated mothers were found on CBCL, CBCL and BRIEF-P, and PPVT respectively. Most interaction effects exceeded 1 standard deviation in favour of the intervention children. The 151 VLBW children performed significantly worse than the term born children on the VAT, BRIEF-P and CBCL., Conclusion: IBAIP effects in VLBW children did not sustain until preschool age on executive functioning, behaviour and cognition. However, the most vulnerable children had a clinical relevant profit from IBAIP. VLBW children performed worse than the term born children. This study is a follow-up at preschool age of the multi-centre RCT of IBAIP versus usual care in VLBW infants. The RCT was performed in Amsterdam, The Netherlands (IBAIP)., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objective: To evaluate the effects of the Infant Behavioral Assessment and Intervention Program(©) (IBAIP) in very low birth weight infants on sensory processing and daily activities at preschool age., Study Design: Follow-up of children included in a randomized controlled trial. Eighty-six infants were enrolled in post-discharge IBAIP until 6 months corrected age, and 90 infants received standard care. At 3.5 years of age, the Sensory Profile-Dutch version (SP-NL) and Pediatric Evaluation of Disability Inventory-Dutch version (PEDI-NL) were administered. For comparison, parents of 41 term-born children also completed the SP-NL., Results: Seventy-six children (88%) in the IBAIP group and 75 children (83%) children in the control group were examined at 44 months corrected age. After adjustment for pre-randomization differences in perinatal characteristics, the IBAIP group outperformed the control group significantly on SP-NL domains of oral sensory processing and sensory processing related to endurance/tone and PEDI-NL domains of mobility. The control group only scored significantly lower than the term group on the SP-NL domain endurance/tone. The very low birth weight groups performed significantly below the PEDI-NL's norm., Conclusion: In line with the positive developmental effects of the IBAIP until 24 months corrected age, independency in mobility in daily activities was improved at 3.5 years., (Copyright © 2011 Mosby, Inc.
