Body composition in adults born preterm with very low birth weight. Pediatr Res 2024; 95:1316-1324. [PMID: 37973945 PMCID: PMC11035121 DOI: 10.1038/s41390-023-02896-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/17/2023] [Accepted: 10/26/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Studies on body composition in preterm very low birth weight (VLBW < 1500 g) survivors are inconsistent and trajectories later in life unknown. We assessed body composition and its change from young to mid-adulthood in VLBW adults. METHODS We studied 137 VLBW adults and 158 term-born controls from two birth cohorts in Finland and Norway at mean age 36 years. Body composition was assessed by 8-polar bioelectrical impedance. We compared results with dual-energy x-ray absorptiometry measurements at 24 years. RESULTS In mid-adulthood, VLBW women and men were shorter than controls. Fat percentage (mean difference in women 1.1%; 95% CI, -1.5% to 3.5%, men 0.8%; -2.0% to 3.6%) and BMI were similar. VLBW women had 2.9 (0.9 to 4.8) kg and VLBW men 5.3 (2.7 to 8.1) kg lower lean body mass than controls, mostly attributable to shorter height. Between young and mid-adulthood, both groups gained fat and lean body mass (p for interaction VLBW x age>0.3). CONCLUSION Compared with term-born controls, VLBW adults had similar body fat percentage but lower lean body mass, largely explained by their shorter height. This could contribute to lower insulin sensitivity and muscular fitness previously found in VLBW survivors and predispose to functional limitations with increasing age. IMPACT In mid-adulthood, individuals born preterm with very low birth weight had similar body fat percentage but lower lean body mass than those born at term. This was largely explained by their shorter height. First study to report longitudinal assessments of body size and composition from young to mid-adulthood in very low birth weight adults. Lower lean body mass in very low birth weight adults could contribute to lower insulin sensitivity and muscular fitness and lead to earlier functional limitations with increasing age.

CEREBELLUM (LONDON, ENGLAND) 2023; 22:877-887. [PMID: 36018542 PMCID: PMC10485085 DOI: 10.1007/s12311-022-01463-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 08/18/2022] [Indexed: 06/15/2023]
Abstract
The aim of this study is to investigate whether scores in ataxia rating scales (ARS) are different in very preterm (VP) preschool and adult participants compared to term controls. This is a case-control study. Sixty VP children (years: 5.5-6.5; gestational age: 23.9-31.7 weeks) and 56 VP adults (years: 17.8-27.9; gestational age: 23.3-32.0 weeks) without major cerebral lesions participated in the study; 60-age and sex-matched term children and 64 term adults for comparison were used in the study intervened with the assessment with International Cooperative Ataxia Rating Scale (ICARS) and Scale for Assessment and Rating of Ataxia (SARA). Main outcome measures are primary outcome: total icars and sara scores in preterm (vp) participants versus controls. Results showed that VP children showed significantly higher total ICARS (M 15.98, SD 6.29, range 4.0-32.0; p < .001) and SARA scores (M 6.5, SD 2.53, range 1.0-15.0; p < .001) than controls (ICARS: M 9.17, SD 3.88, range 2.0-20.0; SARA: M 3.51, SD 1.54, range 1.0-8.0). VP adults also showed significantly higher total ICARS (M 1.0, SD 1.99, range 0.0-11.0; p < .001) and SARA scores (M 0.54, SD 1.08, range 0.0-6.0; p < .001) than controls (ICARS: M 0.11, SD 0.44, range 0.0-2.0; SARA: M 0.04, SD 0.18, range 0.0-1.0). In conclusion, VP children showed significantly higher scores in ARS than controls. These differences were also present in VP adults, suggesting that deficits likely prevail until adulthood. ARS are a time and cost-effective method to screen for difficulties in coordination and balance in a patient group at risk.

Body composition and physical fitness in adults born small for gestational age at term: a prospective cohort study. Sci Rep 2023; 13:3455. [PMID: 36859477 PMCID: PMC9975870 DOI: 10.1038/s41598-023-30371-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 02/21/2023] [Indexed: 03/03/2023] Open
Abstract
There is lack of research on body composition and physical fitness in individuals born small for gestational age (SGA) at term entering mid-adulthood. We aimed to investigate these outcomes in adults born SGA at term. This population-based cohort study included 46 adults born SGA with birth weight < 10th percentile at term (gestational age ≥ 37 weeks) (22 women, 24 men) and 61 adults born at term with birth weight ≥ 10th percentile (35 women, 26 men) at 32 years. Body composition was examined anthropometrically and by 8-polar bioelectrical impedance analysis (Seca® mBCA 515). Fitness was measured by maximal isometric grip strength by a Jamar hand dynamometer, 40-s modified push-up test and 4-min submaximal step test. Participants born SGA were shorter than controls, but other anthropometric measures did not differ between the groups. Men born SGA had 4.8 kg lower grip strength in both dominant (95% CI 0.6 to 9.0) and non-dominant (95% CI 0.4 to 9.2) hand compared with controls. Grip strength differences were partly mediated by height. In conclusion, body composition and physical fitness were similar in adults born SGA and non-SGA at term. Our finding of reduced grip strength in men born SGA may warrant further investigation.

[PMID: 36259094 DOI: 10.1111/aos.15266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 09/05/2022] [Accepted: 09/24/2022] [Indexed: 11/26/2022]
Abstract
PURPOSE The purpose of the study was to study the association between retinal parameters and motor and cognitive outcomes in children born very preterm. METHODS This study is part of a prospective cohort study of very preterm infants (birth weight ≤ 1500 grams/gestational age < 32 weeks). At 11 years of age, the ophthalmological assessment included a retinal optical coherence tomography (OCT) examination of the peripapillary retinal nerve fibre layer (PRNFL) and the macular ganglion cell layer (GCL). The motor performance was assessed with the Movement Assessment Battery for Children-Second Edition (Movement ABC-2), and the cognitive outcome with the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). RESULTS A total of 141 children were included. The mean (SD) average PRNFL was 95 μm (10.2 μm). The mean (SD) macular GCL volume was 0.34 mm3 (0.03 mm3 ). Higher PRNFL thickness associated with higher percentiles for total scores in the motor assessment (b = 0.5, 95% CI 0.1-0.8, p = 0.01) and higher macular GCL volume with higher scores in the cognitive assessment (b = 1.4, 95% CI 0.5-2.3, p = 0.002), also when adjusted for gender, birth weight z-score (birth weight in relation to gestational age) and major brain pathology at term. CONCLUSION The associations between higher average PRNFL thickness and better motor performance as well as higher macular GCL volume and better cognitive performance refer to more generalized changes in the brain of 11-year-old children born very preterm. Retinal OCT examinations might provide a deeper insight than mere eyesight in long-term neurodevelopmental follow-up of children born very preterm.

Multidisciplinary and neuroimaging findings in preterm born very low birthweight individuals from birth to 28 years of age: A systematic review of a Norwegian prospective cohort study. Paediatr Perinat Epidemiol 2022; 36:606-630. [PMID: 35867340 PMCID: PMC9542186 DOI: 10.1111/ppe.12890] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 04/04/2022] [Accepted: 04/11/2022] [Indexed: 12/20/2022]
Abstract
BACKGROUND Children born preterm with very low birthweight (VLBW) face long-lasting neurodevelopmental challenges, where multidisciplinary assessments are warranted. The International Classification of Functioning, Disability and Health (ICF) provides a framework for understanding and conceptualising these outcomes. OBJECTIVES We aimed to review clinical and neuroimaging findings from birth to adulthood in a Norwegian cohort of individuals born preterm with VLBW (gestational age <37 weeks, birthweight ≤1500 g) within the framework of ICF. DATA SOURCES We searched PubMed and Embase for articles reporting results of the Norwegian University of Science and Technology (NTNU) Low Birth Weight in a Lifetime Perspective study. STUDY SELECTION AND DATA EXTRACTION We included original articles reporting proportions of adverse outcomes, mean group differences, risk factors or associations between outcomes. Data were extracted according to ICF's two-level classification. Body functions and structures comprised outcomes of brain structures, cognition, mental health, vision, pain and physical health. Activities and participation comprised motor skills, general and social functioning, education, employment, and health-related quality of life. SYNTHESIS We performed a qualitative synthesis of included articles. Where mean (SD) was reported, we calculated group differences in SD units. RESULTS Fifty-eight publications were included. Within body functions and structures, increased prevalence of brain structure pathology, lower cognitive performance, mental health problems, visual and physical health impairments through childhood, adolescence and young adulthood were reported among preterm VLBW participants compared with controls. Within activities and participation, motor problems, lower general and social functioning, and lower academic attainment were found. Perinatal factors were associated with several outcomes, and longitudinal findings suggested persistent consequences of being born preterm with VLBW. CONCLUSIONS Being born preterm with VLBW has long-term influences on body functions and structures, activities and participation. The ICF is appropriate for assessing general domains of functioning and guiding the management of individuals born preterm with VLBW.

Abstract
Background: Very preterm birth may affect motor performance and social competence up to adulthood. Our objective was to describe perceived loneliness and social competence in children born very preterm in relation to motor impairment. Methods: 165 children born very preterm (birth weight ≤ 1500 g and/or gestational age < 32 weeks) were assessed at 11 years of age. Cerebral palsy (CP) was diagnosed by 2 years of age. At 11 years of age, motor outcome was assessed using the Movement Assessment Battery for Children—Second edition (Movement ABC-2). Loneliness was evaluated by using the Peer Network and Dyadic Loneliness scale and social competence by using the Multisource Assessment of Children’s Social Competence Scale. Results: In total, 6 (4%) children had CP, 18 (11%) had Developmental Coordination Disorder (DCD) (Movement ABC-2 ≤ 5th percentiles), and 141 (85%) had typical motor development. There was no correlation between percentiles for total scores of the Movement ABC-2 and perceived loneliness or social competence when the children with motor impairment (CP or DCD) were excluded. Children with DCD reported less perceived loneliness, but more problems with social competence compared to children with CP. Conclusions: It is important to recognize children born very preterm with DCD to provide interventions and support services to prevent social exclusion.

Abstract
We reviewed literature on long-term motor outcomes of individuals aged five years or older born very preterm (VP: ≤32 weeks of gestation) or with very low birth weight (VLBW: ≤1500g), without cerebral palsy (CP). PubMed produced 2827 articles, whereof 38 were eligible. Assessed by standardised and norm-based motor tests, the Movement Assessment Battery for Children being the most widely used, VP/VLBW individuals showed poorer motor skills compared with term-born controls with differences of approximately 1 SD in magnitude. Some studies assessed subdomains and differences were present in fine motor/manual dexterity, ball skills and gross motor/balance. Prevalence of motor problems varied largely from 8-37% in studies with cut-off at the 5th percentile or -1.5 SD to 12-71% in studies with cut-off at the 15th percentile or -1 SD. This review shows that the degree of motor impairments continues to be substantial among VP/VLBW individuals who do not develop CP.

Abstract
Backgrounds In 2009, the prevention service “Familieambulatoriet” (FA) was established in three pilot hospital areas offering psychosocial support and health monitoring to parents in high risk regarding mental health and substance use, for the purpose of preventing child mental health and developmental problems through preschool years. This study selected new-born health as a preliminary endpoint for evaluation of population effects in three pilot areas, utilizing national statistics for birth cohorts from 2005 to 2013. The aim of the study is to evaluate changes in population new born health incidences associated with the establishment of new supportive and preventive FA-services at three pilot sites from 2009 in contrast to previous years and the remaining country. This quasi-experimental design evaluated changes in populations with new services available not those receiving the services, and controlled for national historical changes, variation between hospital districts, and random variation across the years before or years after the pilot services were introduced. Our hypothesis was to expect reduced frequencies of preterm births, SGA births, low APGAR scores, pediatric transfer, and new born abstinence symptoms in the pilot areas. Methods The baseline was established through 4 years preceding 2009, contrasting changes at pilot sites the following 4 years 2009–2013 using the remaining hospital area populations in Norway 2005–2008 and 2009–2013 as contrasts. Results Related to the introduction of FA services, we found three significant improvements in new born health using mixed effects logistic regression. 1) In the population rate of babies born prematurely with small for gestational age (SGA), using the 10th percentile criteria as the definition; odds ratio (OR) = 0.73 (95% Cl: 0.60 to 0.88). 2) A similar reduction using the 2.5th percentile criteria, although with wider confidence limits; OR = 0.73 (95% Cl: 0.54 to 0.99). 3) A decrease in the frequency of low APGAR scores (0–6) 5 min. after birth; OR = 0.80 (95% Cl: 0.68 to 0.95). Thus, the FA-areas remained significantly lowered on SGA rates or Low APGAR rates across the years after FA establishment, despite considerable variation, in contrast to the baseline years and to the remaining country. No significant effect was found for the outcomes frequency of premature births (unrelated to SGA), SGA among full-term babies, child abstinence symptoms or pediatric transfer of the baby. False negative findings may result from low-rate outcomes or studying the population rather than users. Conclusions Population rates suggest that introducing FA services offering support and monitoring in high-risk families may contribute to improving aspects of new born infant health. Intervention components and strategies should be studied more closely using individual data.

Abstract
BACKGROUND We aimed to examine psychiatric symptoms in adults born preterm with very low birthweight or born at term small for gestational age compared with normal birthweight peers, and examine associations with perinatal factors and childhood motor and cognitive function. METHODS In this longitudinal cohort study, one preterm born group with very low birthweight (VLBW: birthweight ≤1500 g), one term-born Small for Gestational Age (SGA: birthweight <10th percentile) group and one term-born non-SGA control group, were assessed at 26 years of age. Primary outcomes were scores on self-reported questionnaires: Achenbach System of Empirically Based Assessment - Adult Self-Report, The Autism-Spectrum Quotient and Peters et al. Delusions Inventory. Exposure variables were perinatal data, while childhood motor and cognitive function were examined as possible early markers. RESULTS Both the preterm VLBW and the term SGA group reported higher levels of attention, internalizing and externalizing problems compared to the control group. In addition, the VLBW participants reported more critical items and a higher proportion had intermediate level autistic traits, while the SGA participants reported more intrusive behavior. Increasing length of respiratory support and hospital stay in the neonatal period, and motor problems in early adolescence, were associated with adult psychiatric symptoms in the VLBW group. CONCLUSIONS Psychiatric symptoms were frequent in the preterm VLBW group and also in the term-born SGA group. Those who were sickest as babies were most at risk. Motor problems can possibly serve as an early marker of adult psychiatric symptoms in low birthweight individuals.

Abstract
BACKGROUND Birthweight is an important predictor of various fundamental aspects of childhood health and development. AIM To examine the impact of birthweight on childhood balance performance classification and verify if this is replicable and consistent in different populations. STUDY DESIGN Prospective birth cohort study. SUBJECTS To describe heterogeneity in balance skills, latent class analyses were conducted separately with data from the 1958 National Child Development Study - NCDS (n = 12,778), and the 1970 British Cohort Study - BCS (n = 12,115). OUTCOME MEASURES Four balance tasks for NCDS and five balance tasks for BCS. RESULTS Birthweight was assessed as a predictor of balance skills. In both cohorts, two latent classes (good and poor balance skills) were identified. In both cohorts, higher birthweight was associated with a higher likelihood of having good balance skills. Boys were less likely to have good balance compared to girls. CONCLUSIONS The results establish the reproducibility and consistency of the effect of birthweight on balance skills and point to early intervention for individuals with lower birthweight to mitigate the impact of motor impairment.

Abstract
Purpose: The developing brain of a premature infant is vulnerable to injury. As a result, the long-term consequences of a premature birth include motor deficits, cognitive and behavioural problems. It is crucial to identify motor dysfunction during the preschool period because it interferes with a child's ability to explore the world. The goals of this study were to (1) provide preliminary data on the gross motor outcomes of children born prematurely and (2) determine the proportion and characteristics of the children who had maintained delays over the course of follow-up. Method: A retrospective chart review was conducted on all infants monitored by a neonatal follow-up programme. Each child was assessed by a single physiotherapist from birth until age 2 years. Of the 107 cases identified, 97 individuals were retained for analysis; they had a mean gestational age of 31.1 (SD 2.9) weeks and a mean birth weight of 1.66 (SD 0.53) kilograms. Results: The majority of children assessed were found to have gross motor outcomes in the average range. Children with scores below the average range were most often born very preterm (VPT) or moderately preterm (MPT), with very low or low birth weight, respectively. A total of 17 participants were referred to physiotherapy to address the gross motor delays identified in the follow-up programme; 14 of these 17 had previously been identified as delayed and were being monitored. Late preterm (LPT) children (n=6) were most often referred, followed by those born extremely preterm (EPT) and VPT (n=4). In total, 56 children were identified as delayed at one assessment point but were found to be within normal limits by the end of the follow-up period. Conclusion: It is important to periodically monitor premature children. A longitudinal, population-based study is also needed to provide more data on the predictors and long-term motor outcomes of MPT and LPT children.

Abstract
OBJECTIVE To investigate self-reported pain in young adults with a low birth weight. MATERIALS AND METHODS This study was a part of a long-term follow-up study of preterm very low birth weight (VLBW; birth weight ≤1500 g), term small for gestational age (SGA; birth weight <10th percentile adjusted for sex and parity), and control young adults born during 1986 to 1988. Of the 300 individuals invited, 216 (62 VLBW, 67 term SGA, and 87 controls) completed a pain questionnaire. Of these, 151 (70%) had answered a pain severity question at 19 years. Chronic pain was defined as pain lasting for >6 months and being moderate, severe, or very severe during the past 4 weeks. RESULTS The prevalence of chronic pain at 26 years was 16% in the VLBW group, 21% in the term SGA group, and 7% in the control group. The VLBW and the term SGA groups had higher odds ratios for chronic pain (crude OR, 2.6; 95% CI, 0.9-7.6 for the VLBW group and crude OR, 3.6; 95% CI, 1.3-9.9 for the term SGA group vs. controls). The main results remained after adjusting for potential confounding factors. Some attenuation was observed when adjusting for anxiety and depressive problems. Moderate to very severe pain increased from 16% to 41% in the term SGA group from 19 to 26 years, whereas less changes were seen in the VLBW and the control groups. DISCUSSION Results of our study imply that pain should be in focus when conducting long-term follow-up programs of individuals with a low birth weight.

Abstract
BACKGROUND Preterm (PT) birth and low birth mass (LBW) can impair growth and development of children and may therefore affect their physical performance up to adulthood. AIMS Our aim was to evaluate long-term consequences of prematurity, especially (an)aerobic exercise capacity and agility up to adulthood, by comparing premature and full-term (FT) individuals. STUDY DESIGN, SUBJECTS From 474 subjects born in 1987, who were enrolled into a longitudinal study, 396 (178 PT and 218 FT (with 127 of them LBW)) were followed-up into their early adulthood. Their mass, respiratory status at birth, and results of SLOfit monitoring system (i.e. results of exercise capacity and agility) were monitored on a yearly basis from their age of 8 to 18years. Data were compared statistically with Student t-test or ANOVA. OUTCOME MEASURES, RESULTS PT (or LBW) individuals performed aerobic (time of 600-meter run of females) and the majority of anaerobic tests (sit-ups, standing broad jump, and time of 60-meter run, but not bent arm hang) worse (p<0.05) than FT individuals. Before puberty, however, the agility and fine motor tests (arm plate tapping, polygon backwards, and standing reach touch) were performed better (p<0.05) by PT (or LBW) females, as compared to their FT peers, with no similar results in males. CONCLUSIONS Our results clearly demonstrate that prematurity (especially extreme prematurity) diminishes exercise capacity and agility on the long-term scale, therefore, PT children should be encouraged towards more regular participation in physical activities from early childhood onwards.

Abstract
BACKGROUND Skin-to-skin care immediately following delivery is a common practice for term infants and has been shown to improve cardiorespiratory stability, facilitate early bonding, and promote breastfeeding. Since 2007, the use of skin-to-skin care has been practiced for preterm infants from 32 weeks of gestation in the delivery room at St. Olav's University Hospital. In the present study we aim to investigate whether skin-to-skin care following delivery is safe, and how it affects early and late outcomes compared to standard care for very preterm infants. METHODS/DESIGN A randomized controlled trial (RCT) of skin-to-skin care in the delivery room for very preterm infants born at gestational age 280-316 weeks with birth weight >1000 grams. Infants with severe congenital malformations or need of intubation in the delivery room are excluded. A detailed checklist and a flowchart were prepared for the study, and all involved professionals (neonatologists, neonatal nurses, obstetricians, anesthesiologists, midwives) participated in medical simulation training prior to study start on February 1, 2014. A consultant in neonatology and a neonatal nurse are present at all deliveries. Infants with birth weight <1500 grams receive an intravenous line with glucose, amino acids, and caffeine citrate in the delivery room. Infants with gestational age <30 weeks are routinely put on continuous positive airway pressure (CPAP). After initial stabilization, infants are randomized to skin-to-skin care or are transferred to the nursery in an incubator. Primary outcome is cognitive development at 2 years measured with the Bayley Scales of Infant Development, Third Edition. Secondary outcomes are safety defined as hypothermia, respiratory failure, and/or cardiopulmonary resuscitation, physiological stability after birth and motor, language and cognitive development at 1 year for the child, and mental health measured with the State-Trait Anxiety Inventory (STAI) at discharge, and at 3 months and 2 years after expected date of delivery for the mothers. DISCUSSION The study may have important implications for the initial care for very preterm infants after delivery and increase our understanding of how early skin-to-skin care affects preterm infants and their mothers. TRIAL REGISTRATION ClinicalTrials, NCT02024854 . Registered on 19 December 2013.

Long-term effects of peer victimization on social outcomes through the fourth decade of life in individuals born at normal or extremely low birthweight.

Abstract
Exposure to early adversity is known to have deleterious effects on brain-behaviour relations across the lifespan and across a range of domains. Here, we tested a cumulative risk hypothesis of adult social functioning and health outcomes in the fourth decade of life, using the oldest known longitudinally followed cohort of survivors of extremely low birthweight (ELBW; <1,000 g). We investigated the additional impact of peer victimization in youth on social outcomes at age 29-36 years in ELBW survivors and matched normal birthweight (NBW; >2,500 g) participants. In the combined sample, peer victimization was associated with lower likelihood of having children and household income, poorer family functioning and self-esteem, more loneliness and chronic health conditions, less social support, and increased likelihood for contact with police. Moderation analyses indicated that among ELBW survivors, compared to their NBW counterparts, victimization was more strongly associated with being convicted of a crime and with having chronic health conditions. These findings highlight the negative long-term impact of peer victimization on all children and that some outcomes may be differentially affected by prenatal and early post-natal environments. Statement of contribution What is already known on this subject Exposure to early adversity has deleterious effects on brain-behaviour relations across the lifespan. Extremely premature children have higher rates of exposure to adversities, including peer victimization. Peer victimization is associated with adverse outcomes in adulthood in those born at term. What does this study add? Victimization negatively impacts the social outcomes of those born extremely premature and at term into adulthood. Associations appear to be affected by individual differences in prenatal and early post-natal environments. Intervention is crucial when peer victimization occurs in children at risk, as well as those typically developing.

Abstract
BACKGROUND Preterm infants are at a higher risk for poor motor outcome than term infants. This study aimed to describe the long-term motor profile in very preterm born children. METHODS A total of 98 very preterm infants were included. Volumetric brain magnetic resonance imaging (MRI) was performed at term age, and the Movement Assessment Battery for Children-Second Edition (The Movement ABC-2) was employed at 11 y of age. The diagnosis of Developmental Coordination Disorder (DCD) was determined at 11 y of age according to the International Classification of Diseases. RESULTS Eighty-two of 98 (84%) very preterm infants had normal motor development at 11 y of age. In these children, the mean percentile for the total test score in the Movement ABC-2 examinations was 42 (SD 20). Eight (8%) children had DCD. The mean percentile in these children was 4 (SD 2). Eight (8%) children had CP. Their mean percentile was 6 (SD 14). Decreased volumes in all brain regions associated with lower Movement ABC-2 total scores. CONCLUSION The majority of the very preterm infants had normal motor development at 11 y of age. Volumetric brain MRI at term age provides a potential tool to identify risk groups for later neuromotor impairment.

Abstract
BACKGROUND While children born at extremely low birth weight (ELBW; <1000 g) are at elevated risk for peer victimization, no research has examined its effects on mental health in adulthood. METHODS ELBW survivors and matched normal birth weight (NBW; >2500 g) controls were part of a prospective, population-based study in Ontario, Canada. Peer victimization before age 16 was self-reported at age 22 to 26 years by using a 10-point measure. Presence of psychiatric disorders was examined at age 22 to 26 years (ELBW n = 142, NBW n = 133) and age 29 to 36 years (ELBW n = 84, NBW n = 90). RESULTS After adjustment for confounding variables, for each 1-point increase in the peer victimization score, ELBW survivors had increased odds of current depressive (odds ratio [OR] = 1.67, 95% confidence interval [CI], 1.23-2.28), anxiety (OR = 1.36, 95% CI, 1.05-1.76), avoidant (OR = 1.39, 95% CI, 1.08-1.79), antisocial (OR = 1.92, 95% CI, 1.06-2.87), and attention-deficit/hyperactivity (OR = 1.39, 95% CI, 1.06-1.83) problems at age 22 to 26 years. At age 29 to 36 years, peer victimization score predicted increased odds of current panic disorder (OR = 1.69, 95% CI, 1.01-2.83) and obsessive-compulsive disorder (OR = 3.56, 95% CI, 1.25-10.09). For NBW controls, peer victimization predicted increased odds of antisocial problems at age 22 to 26 years. CONCLUSIONS ELBW survivorsand NBW participants are vulnerable to the adverse psychiatric effects of childhood peer victimization in adulthood.

Abstract
BACKGROUND Health outcomes throughout the life course have been linked to fetal growth restriction and low birthweight. A variety of measures exist to define low birthweight, with a lack of consensus regarding which predict adverse outcome. OBJECTIVES To evaluate the relationship between birthweight standards and childhood and adult outcomes in term-born infants (≥37 weeks' gestation). SEARCH STRATEGY MEDLINE (1966-January 2011), EMBASE (1980-January 2011), and the Cochrane Library (2011:1) and MEDION were included. SELECTION CRITERIA Studies comprising live term-born infants (gestation ≥37 completed weeks), with weight or other anthropometric measurements recorded at birth along with childhood and adult outcomes. DATA COLLECTION AND ANALYSIS Data were extracted to populate 2 × 2 tables relating birthweight standard with outcome, and meta-analysis was performed where possible. MAIN RESULTS Fifty-nine articles (2 600 383 individuals) were selected. There was no significant relationship between birthweight <2.5 kg (odds ratio [OR] 0.98, 95% confidence intervals [CI] 0.87-1.10) and composite measure of childhood morbidity. Weight <10th centile on the population nomogram showed a small association (OR 1.49, 95% CI 1.02-2.19) for the same outcome. There was no significant association between either of the above measures and adult morbidity. The relationship between other measures and individual outcomes varied. AUTHOR'S CONCLUSIONS The association between low birthweight, by any definition, and childhood and adult morbidity was inconsistent. None of the current standards of low birthweight was a good predictor of adverse outcome.

Neuroimage 2015; 109:493-504. [PMID: 25592994 DOI: 10.1016/j.neuroimage.2015.01.019] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2014] [Revised: 12/30/2014] [Accepted: 01/06/2015] [Indexed: 11/15/2022] Open
Abstract
Individuals born preterm and at very low birth weight (birth weight ≤ 1500 g) are at an increased risk of perinatal brain injury and neurodevelopmental deficits over the long term. This study examined whether this clinical group has more problems with visual-motor integration, motor coordination, and visual perception compared to term-born controls, and related these findings to cortical surface area and thickness and white matter fractional anisotropy. Forty-seven preterm-born very low birth weight individuals and 56 term-born controls were examined at 18-22 years of age with a combined cognitive, morphometric MRI, and diffusion tensor imaging evaluation in Trondheim, Norway. Visual-motor skills were evaluated with the Beery-Buktenica Developmental Test of Visual-Motor Integration-V (VMI) copying test and its supplemental tests of motor coordination and visual perception. 3D T1-weighted MPRAGE images and diffusion tensor imaging were done at 1.5 T. Cortical reconstruction generated in FreeSurfer and voxelwise maps of fractional anisotropy calculated with Tract-Based Spatial Statistics were used to explore the relationship between MRI findings and cognitive results. Very low birth weight individuals had significantly lower scores on the copying and motor coordination tests compared with controls. In the very low birth weight group, VMI scores showed significant positive relationships with cortical surface area in widespread regions, with reductions of the superior temporal gyrus, insula, and medial occipital lobe in conjunction with the posterior ventral temporal lobe. Visual perception scores also showed positive relationships with cortical thickness in the very low birth weight group, primarily in the lateral occipito-temporo-parietal junction, the superior temporal gyrus, insula, and superior parietal regions. In the very low birth weight group, visual-motor performance correlated positively with fractional anisotropy especially in the corpus callosum, inferior fronto-occipital fasciculus bilaterally, and anterior thalamic radiation bilaterally, driven primarily by an increase in radial diffusivity. VMI scores did not demonstrate a significant relationship to cortical surface area, cortical thickness, or diffusion measures in the control group. Our results indicate that visual-motor integration problems persist into adulthood for very low birth weight individuals, which may be due to structural alterations in several specific gray-white matter networks. Visual-motor deficits appear related to reduced surface area of motor and visual cortices and disturbed connectivity in long association tracts containing visual and motor information. We conjecture that these outcomes may be due to perinatal brain injury or aberrant cortical development secondary to injury or due to very preterm birth.

Abstract
OBJECTIVE Motor development is frequently reported to be impaired in very low birth weight (VLBW) infants, but little is known about the moderately low birth weight (MLBW) infants. The aim of this study was to investigate whether MLBW preterm infants present developmental delay. METHODS In a historical cohort study, 18±2 month-old infants with a history of low birth weight (LBW) were identified. All infants with complications of LBW with negative effects on development were excluded. Healthy infants with normal birth weight (2500-4000 g) were included as controls. All infants were evaluated by the Peabody Developmental Motor Scale II (PDMS-2) test and final scores compared between the two groups. FINDING 88 infants including 58 MLBW and 30 NBW with a mean birth weight of 1900±382.4 g and 3150±473.5 g respectively, were studied. In the MLBW group, gross and fine motor skill scores were below average in 6 (6.8%) and 10 (17%) infants, respectively. There were no significant differences between the two groups according to gross motor quotient (102.5±5.5 in NBW vs 100.1±7.2 in MLBW; P=0.1), but MLBW infants achieved significantly lower scores in fine motor (93.3±5.4 vs 99.6±5.0; P=0.001) and total motor quotient (97.0±5.9 vs 101.53±5.0; P=0.001). CONCLUSION The finding of this study show developmental defects in fine motor skills in MLBW infants. Accurate monitoring of the developmental status of this population should be emphasized for an earlier recognition and intervention.

Abstract
BACKGROUND Motor developmental impairment is a common symptom in low birth weight neonates. The Peabody Developmental Motor Scales-second edition is an instrument for measuring motor abilities in these infants. This study aimed to validate the Peabody Developmental Motor Scales-second edition in Iran. METHODS This was a prospective clinical validation study. The reliability and validity of the original measure were performed in accordance with published guidelines. To collect data, a total of 88 infants including 58 LBW infants and 30 normal birth weight control patients were included in the study, and the measure was completed for them. The Bayley Scales of Infant Development, second edition, and the Motor Scale (Psychomotor Development Index) also were completed for the study samples. To test reliability, the internal consistency was assessed by Cronbach alpha coefficient. Test-retest reliability was performed using Intraclass Correlation Coefficient at 1-week interval. Validity was evaluated using known groups comparison and criterion validity (convergent validity). RESULTS The Cronbach alpha coefficient for the Peabody Developmental Motor Scales-second edition was 0.92. Further analysis also indicated that test-retest reliability was excellent (Intraclass Correlation Coefficient = .98). Validity as performed by known groups comparison indicated satisfactory result. The instrument well discriminated among subgroups of the study samples that differed in birth weight. The Psychomotor Development Index score correlated strongly with the Peabody Developmental Motor Scales-second edition (r for Fine Motor Scale = .91, P < 0.001 and r for the Peabody Developmental Motor Scales-second edition Gross Motor Scale = .93, P < 0.001). CONCLUSIONS The findings suggest that the Iranian version of Peabody Developmental Motor Scales-second edition is a reliable and valid measure. It can now be used in clinical settings for assessing motor development in low birth weight infants.

Abstract
In Western society, impaired uteroplacental blood flow is the major cause of human intrauterine growth restriction. Infants born small and who experience late childhood accelerated growth have an increased risk of developing adult diseases. Recent studies also suggest a link between birth weight and altered adult behavior, particularly relating to motor function, learning and memory, depression and schizophrenia. The aim of this study was to determine the relative influence of prenatal and postnatal growth restriction on adult behavioral outcomes in male and female rats. Uteroplacental insufficiency was induced in Wistar Kyoto rats by bilateral uterine vessel ligation on day 18 of gestation producing growth-restricted offspring (Restricted group). The Control group had sham surgery. Another group underwent sham surgery, with a reduction in litter size to five at birth equivalent to the Restricted litter size (Reduced Litter group). At 6 months of age, a series of behavioral tests were conducted in male and female offspring. Growth restriction did not impair motor function. In fact, Restricted and Reduced Litter males showed enhanced motor performance compared with Controls (P < 0.05). Spatial memory was greater in Restricted females only (P < 0.05). The Porsolts test was unremarkable, however, males exhibited more depressive-like behavior than females (P < 0.05). A reduction in sensorimotor gating function was identified in Reduced Litter males and females (P < 0.05). We have demonstrated that growth restriction and/or a poor lactational environment can affect adult rat behavior, particularly balance and coordination, memory and learning, and sensorimotor gating function, in a sex-specific manner.

Abstract
OBJECTIVE To assess the effects of late small-for-gestational-age (SGA) birth and late prematurity on cognitive outcomes and structural changes in the central nervous system at primary school age, using a novel approach to examine changes in neuronal integrity of the retina. METHODS We conducted a cross-sectional study of 347 children aged 6-13 years, including in the analysis only infants born after 34 weeks' gestation. We recorded all perinatal outcomes through a survey of parents. Neuronal damage was evaluated using optical coherence tomography of the retina. In a subgroup of 112 children aged 6-8 years, visuospatial perception was evaluated with the Children's Bender Visual Motor Gestalt Test. RESULTS The proportions of SGA and late preterm children were 11.8 and 6.3%, respectively. Prematurity and SGA were simultaneously present in five children. When compared with controls, SGA children showed significantly lower than average retinal nerve fiber layer (RNFL) thickness (94.1 vs 98.8 μm; P = 0.007) and an increased percentage of abnormal Bender scores (27.3 vs 6.2%; P = 0.017) (odds ratio 5.6 (95% CI, 1.2-26.8)). These differences increased when late SGA infants with a birth weight below the 3(rd) percentile were compared with SGA infants with a birth weight between the 3(rd) and 10(th) percentiles and with controls, for RNFL thickness (92.5 vs 94.6 and 98.8 μm, respectively; P = 0.021) and abnormal Bender tests (33.3 vs 25.0 and 6.2%, respectively; P = 0.036). However, no differences were found in retinal structure and visuomotor performance between late preterm and term infants. CONCLUSIONS These data suggest that late SGA and late prematurity induce a distinct neuronal pattern of structural changes that persist at school age. Late-onset SGA infants are at increased risk for axonal loss in the retina and present specific visuomotor difficulties.

Abstract
Low birth weight (LBW) and hypoxia are among the environmental factors most reliably associated with schizophrenia; however, the nature of this relationship is unclear and both gene-environment interaction and gene-environment covariation models have been proposed as explanations. High-risk (HR) designs that explore whether obstetric complications differentially predict outcomes in offspring at low risk (LR) vs HR for schizophrenia, while accounting for differences in rates of maternal risk factors, may shed light on this question. This study used prospectively obtained data to examine relationships between LBW and hypoxia on school outcome at age 15-16 years in a Finnish sample of 1070 offspring at LR for schizophrenia and 373 offspring at HR for schizophrenia, based on parental psychiatric history. Controlling for offspring sex, maternal smoking, social support, parity, age, and number of prenatal care visits, HR offspring performed worse than LR offspring across academic, nonacademic, and physical education domains. LBW predicted poorer academic and physical education performance in HR offspring, but not in LR offspring, and this association was similar for offspring of fathers vs mothers with schizophrenia. Hypoxia predicted poorer physical education score across risk groups. Rates of LBW and hypoxia were similar for LR and HR offspring and for offspring of fathers vs mothers with schizophrenia. Results support the hypothesis that genetic susceptibility to schizophrenia confers augmented vulnerability of the developing brain to the effects of obstetric complications, possibly via epigenetic mechanisms.

Abstract
BACKGROUND Motor skills have previously not been reported in young adults born with very low birth weight (VLBW), although they are commonly reported in children and adolescents. AIM To compare fine and gross motor skills in VLBW young adults with matched term-born controls, and to study longitudinal changes in the VLBW group. STUDY DESIGN A geographically based follow-up study of a VLBW group and a control group. SUBJECTS Thirty-six VLBW (birth weight ≤ 1500 g) young adults, including four participants with cerebral palsy (CP), and 37 matched controls (birth weight ≥ 10th centile) were examined at 14 and 23 years of age. OUTCOME MEASURES Fine and gross motor skills were assessed using Grooved Pegboard test (GP), Trail Making Test-5 (TMT-5), Movement Assessment Battery for Children-2 (Movement ABC-2) and High-level Mobility Assessment Tool (HiMAT). RESULTS VLBW young adults were slower than controls on GP (p = 0.026) and TMT-5 (p < 0.001). Mean total Movement ABC-2 score was 69.7 ± 20.2 in the VLBW group compared with 74.1 ± 14.4 in the control group (p = 0.017). Differences were also seen in manual dexterity and balance. Additionally, HiMAT showed reduced balance and speed in gross motor skills in the VLBW group. The proportion of participants with motor problems did not change between age 14 and 23. After exclusion of participants with CP, scores were essentially the same. CONCLUSION VLBW young adults had overall poorer fine and gross motor skills compared with controls. Reduced speed seemed to be an underlying problem. Longitudinal findings indicate that VLBW children have not outgrown their motor problems when entering adulthood.

Abstract
The objective of the paper is to explore bottom-up auditory and top-down cognitive processing abilities as part of long-term outcome assessment of preterm birth. Fifty-five adolescents (age 13-15) born with very low birth weight (VLBW) were compared to 80 matched controls born to term, using three consonant-vowel dichotic listening (DL) instruction conditions (non-forced, forced-right and forced-left). DL scores were correlated with cortical gray matter thickness derived from T1-weighted structural MRI volumes using FreeSurfer to examine group differences also in the neural correlates of higher cognitive processes. While showing normal bottom-up processing, VLBW adolescents displayed impaired top-down controlled conflict processing related to significant cortical thickness differences in left superior temporal gryus and anterior cingulate cortex. Preterm birth with VLBW induces fundamental changes in brain function and structure posing a risk for long-term neurocognitive impairments. Deficits emerge in situations of increasing cognitive conflict and can be related to measures of executive functions as well as morphology.

Abstract
OBJECTIVE To assess cognitive outcomes and structural changes in the central nervous system, the latter using a novel approach to examine changes in neuronal integrity of the optic nerve, in children at 5-6½ years of age who were born small-for-gestational age (SGA) at term having shown normal umbilical artery (UA) Doppler. METHODS We compared neuronal damage, cognitive deficits and visuospatial perception in two cohorts of infants, one born SGA (n = 40) and one born appropriate-for-gestational age (AGA) (n = 39) in weight. Neuronal damage was evaluated using optical coherence tomography (OCT) of the optic nerve. Cognitive deficits were assessed with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) test. Visuospatial perception was evaluated with Rey-Osterreich Complex Figure (ROCF) tasks. RESULTS Children from the SGA group had a significantly thinner average retinal nerve fiber layer (RNFL) compared with those from the AGA group (98.2 vs 104.5 µm, P = 0.012). Children from the SGA group exhibited impaired performance in copy tasks on the ROCF (3.27 vs 3.56, P = 0.036) and a higher rate of suboptimal WPPSI test performance intelligence quotient scores (15% vs 0%; P = 0.025) compared with those from the AGA group. CONCLUSION Term infants with normal UA Doppler born SGA are at increased risk for cognitive deficits and axonal loss in the RNFL at the age of 5-6½ years.

Abstract
BACKGROUND Within the able majority of ELBW survivors, there is a lack of identified predictors of which children will require extra support despite having escaped significant disability. AIMS Investigate the predictive validity of early motor scores, compared to that of perinatal descriptors or early growth, on long-term motor impairment in non-disabled ELBW (<1000g) children. STUDY DESIGN Prospective longitudinal study. OUTCOME MEASURES 48 non-disabled ELBW children (27 male) completed the Neurosensory Motor Developmental Assessment (NSMDA) at 8 months, 2 years and 4 years post term and The Motor Assessment Battery for Children (MABC) at 11-13 years of age. Other possible predictors of long-term outcomes (gestational age, birthweight, multiple birth, head circumference measures and gender) were retrieved from the records. RESULTS Early motor assessment (NSMDA score) independently predicted the MABC total score at 11-13 years of age with a positive predictive value of 87% by 4 years post term. There was increased risk of long-term motor impairment associated with male gender but the degree of prematurity, multiple birth status or early growth measures did not predict motor outcome. Postural control and sensory motor scores at 4 years post term, rather than neurological score, were associated with long-term motor outcomes for the ELBW children at 11-13 years of age. CONCLUSIONS Early motor scores are valid markers of long-term motor outcomes for "apparently normal" ELBW children. Early postural competence and sensory motor function are discriminating in regards to long-term motor function in neurologically normal ELBW children.

Abstract
Children born preterm have a higher risk for developing motor, cognitive, and behavioral problems. Motor problems can occur in combination with working memory problems, and working memory is important for explicit learning of motor skills. The relation between motor learning and working memory has never been reviewed. The goal of this review was to provide an overview of motor learning, visual working memory and the role of working memory on motor learning in preterm children. A systematic review conducted in four databases identified 38 relevant articles, which were evaluated for methodological quality. Only 4 of 38 articles discussed motor learning in preterm children. Thirty-four studies reported on visual working memory; preterm birth affected performance on visual working memory tests. Information regarding motor learning and the role of working memory on the different components of motor learning was not available. Future research should address this issue. Insight in the relation between motor learning and visual working memory may contribute to the development of evidence based intervention programs for children born preterm.

Abstract
OBJECTIVE : To systematically review and synthesize the literature to document the association between infants born very preterm and/or very low birth weight (VLBW) and the presence of developmental coordination disorder (DCD) at school age. METHODS : Seven databases were systematically searched. Studies were included if they examined very preterm (<32 weeks) and/or VLBW (<1500 g) infants to school age (age, 5-18 years), had a full-term and/or normal birth weight comparison group, and used a formal measure of motor impairment. Studies that included only infants who were small for gestational age or diagnosed with cerebral palsy were excluded. Two independent reviewers completed abstract and full-text screening, data extraction, and quality assessment of included studies. RESULTS : Sixteen articles were included, with 7 studies incorporated into 2 meta-analyses using cutoff scores of either <5th or 5-15th percentile on the Movement Assessment Battery for Children. Both analyses showed a significant increase in the likelihood of DCD for children born very preterm and/or 1500 g or less, with odds ratios of 6.29 (95% confidence interval, 4.37-9.05, p < .00001) and 8.66 (95% confidence interval, 3.40-22.07, p < .00001) for <5th or 5-15th percentile scores, respectively. CONCLUSIONS : Consistent across studies, DCD is more prevalent in the VLBW/very preterm population than full-term/normal birth weight control children and the general school-age population, with significantly greater odds of developing the disorder. Clinical practice should focus on early identification of and intervention for children with DCD, while research should focus on determining the mechanisms underlying DCD in the preterm population.

Abstract
Birth weight is an indicator of prenatal development associated with health in infancy and childhood, and may be affected by the family environment experienced by the mother during pregnancy. Using data from KwaZulu-Natal, South Africa, we explore the importance of the mother's access to the father and grandparents of the child during pregnancy. Controlling for household socio-economic indicators and maternal characteristics, the survival and residence of the biological father with the mother are positively associated with birth weight. The type of relationship seems to matter: married women have the heaviest newborns, but co-residence with a non-marital partner is also associated with higher birth weight. Access to the maternal grandmother may also be important: women whose mothers are alive have heavier newborns, but no additional benefit is observed from residing together. Co-residence with any grandparent is not associated with birth weight after controlling for the mother's partnership.

Abstract
AIM the aim of this study was to assess cognitive function at the age of 19 years in individuals of very low birthweight (VLBW; ≤ 1500g) and in term-born comparison individuals. METHOD in this hospital-based follow-up study, 55 VLBW participants (30 males, 25 females; mean birthweight 1217g, SD 233g; mean gestational age 29.1wks, SD 2.5wks) and 81 comparison individuals (42 males, 39 females; mean birthweight 3707g, SD 433g; mean gestational age 39.7wks, SD 1.2wks) were examined with a standardized IQ test (Wechsler Adult Intelligence Scale III) to assess general cognitive ability. RESULTS over half (53%) of the VLBW participants achieved a low IQ score (defined as >1SD below the mean in the comparison group; odds ratio 6.4 vs comparison individuals; 95% confidence interval 2.8-14.4; p<0.001). None of the VLBW group, compared with 22% of the comparison individuals, achieved a high IQ score (>1SD above the comparison mean). VLBW participants scored lower than comparison individuals on full, verbal, and performance IQ, as well as on all four indices (p ≤0.001). The subtest profile indicated problems on all subtests, but especially on those related to arithmetic and visual-perceptual tasks. INTERPRETATIONS few studies have undertaken a comprehensive assessment of general cognitive outcome (IQ) among young adults of VLBW. Our results indicate that VLBW seems to have a global and lasting impact on cognitive ability. Full-scale IQ assessment may reveal important learning problems in young adults of VLBW, and should be performed to inform appropriate assistance to enhance academic achievement and the chances of permanent employment as adults.

Abstract
Preterm birth with very low birth weight (VLBW, ≤1500 g) is connected to reduced white matter (WM) integrity in childhood and adolescence. These changes in WM are correlated to motor, sensory and neuropsychological impairments. CNS myelination continues into the early twenties, but the consequences of this for WM integrity in VLBWs have not been explored. DTI and tract based spatial statistics (TBSS) was carried out to test for voxelwise differences in fractional anisotropy (FA), eigenvalues and mean diffusivity (MD) between a preterm VLBW group (n=49) and a control group born at term (n=59) at 18-22 years of age. TBSS was also used to explore the relationship between perinatal clinical data and general cognitive ability (total IQ), respectively, and the DTI metrics (FA and MD), with gender and age as a confounder. In the VLBW group several major WM tracts particularly in the posterior region had significantly reduced FA caused by an increase in the two lowest eigenvalues. MD was significantly increased in the VLBWs in 50% of the same regions as the FA changes, but encompassing also more peripheral WM. In the VLBW group, FA was found to correlate positively with birth weight and negatively with number of days in intensive care and on mechanical ventilator, particularly in the corpus callosum. FA was found to correlate positively with total IQ in the young preterm adults. In the controls there was no correlation between FA and total IQ. Our results indicate that the neurologic sequelae of preterm birth with VLBW are a lifelong condition inducing structural and functional impairments also in adulthood in VLBW survivors. The greatest risk of having reduced WM integrity in adulthood was found in the most immature VLBW neonates requiring mechanical ventilation and long-term intensive care.

Abstract
OBJETIVO: Realizar uma revisão da literatura sobre fatores que influenciam o déficit de desenvolvimento motor em crianças com baixo peso ao nascer. FONTES DE DADOS: Estudos com crianças com baixo peso ao nascer, publicados no período de 1984 a 2008 nas bases de dados Medline e SciELO, usando as palavras chaves "baixo peso ao nascer" e " desenvolvimento motor", na língua inglesa. SÍNTESE DE DADOS: Embora diferenças no desenvolvimento entre crianças nascidas a termo e pré-termo sejam observadas com certa frequência, o seu entendimento ainda é um grande desafio para profissionais da saúde. O uso de diferentes testes e escores dificulta o diagnóstico, o manejo e a previsão dos déficits de desenvolvimento. Resultados heterogêneos são relatados dependendo do método de avaliação, idade e população estudada. Como é esperado que crianças com baixo peso ao nascer tenham risco para problemas cognitivos, motores e comportamentais, estudos abordando práticas de intervenção precoce seriam esperados; entretanto, isso não é observado. CONCLUSÕES: Devido à relação entre desenvolvimento motor e os outros domínios de desenvolvimento, é importante que o achado da alteração motora seja usado como uma variável diagnóstica e que os resultados encontrados sejam padronizados para melhor entendimento dos déficits que crianças com baixo peso ao nascer possam desenvolver

Abstract
OBJECTIVE To determine the effect of very low birth weight (VLBW; <1500 g) and moderately low birth weight (MLBW; 1500-2499 g) on children's mental and motor development and physical growth during the first 2 years of life and whether VLBW and MLBW babies catch up to normal birth weight (NBW; > or =2500 g) children by age 2. METHODS We use data on dizygotic (DZ) and monozygotic (MZ) twins and singleton births from the first two waves of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a nationally representative dataset of children born in the US in 2001. We estimate the effects of VLBW and MLBW on children's mental and motor development scores, weight-for-age, weight-for-length, weight-for-height, and length-for-age z-scores at 9 months and 2 years. We examine whether differences in outcomes within twin pairs are related to differences in their birth weights. The within-twins analysis is conducted on samples of DZ and MZ twins. For comparison, we also estimate birth weight effects on child outcomes from multivariate linear regression models using the full singleton and twins' sample. We also estimate the effect of being small-for-gestational age (SGA; birth weight <10th percentile for gestation) using the same set of models in order to separate out the effects of fetal growth restriction from prematurity. RESULTS Evaluation of all births showed that VLBW and MLBW have large negative effects on mental development, motor development, and growth at 9 months and 2 years of age. However, results from within-twin models with DZ twins that control for shared maternal and environmental factors showed much less effect of birth weight on mental or motor development, but continued large effects on growth for the VLBW group. Within-twin models with MZ twins that control for shared maternal, environmental, and genetic factors showed statistically insignificant effects of birth weight on mental and motor development, but continued effects on growth. Similar patterns were found when examining the effects of SGA. CONCLUSIONS After controlling for the influence of maternal, environmental, and genetic factors, low birth weight has at most a small negative effect on children's mental and motor development in their first 2 years of life. However, low birth weight is a major risk factor for children's physical growth in the early years and there is no evidence of catch-up by age 2.

Abstract
BACKGROUND Motor problems are common in children born preterm or small for gestational age. AIM To study the predictive value of early motor assessments for later motor skills. SUBJECTS Twenty-eight children born preterm with very low birth weight (VLBW: birth weight <or=1500 g), 57 children born small for gestational age (SGA: birth weight <10th centile) at term and 77 term-born controls with normal birth weight. METHODS The psychomotor development index (PDI) of the Bayley Scales of Infant Development was used as a measure of motor skills at age one, the Peabody Developmental Motor Scales (PDMS) at age five and the Movement Assessment Battery for Children (Movement ABC) at age 14. Low/borderline low scores were defined as <-2SD/-1SD (PDI) or <5th/15th centile (PDMS; Movement ABC). RESULTS In the VLBW group, motor problems in adolescence were identified both by low PDI (sensitivity: 0.80; 95%CI:0.38-0.96) and PDMS scores (sensitivity: 0.83; 95%CI:0.44-0.97). In the SGA and the control group sensitivity was poor for low PDI and moderate for low PDMS scores. However, in the SGA group, sensitivity increased when borderline low PDMS scores were used as cut-off (sensitivity: 0.75; 95%CI:0.41-0.93). Specificity of PDI and PDMS was high in all three groups. CONCLUSIONS Both PDI and PDMS may be valuable tools for early identification of motor problems in VLBW children, whereas PDMS best predicted motor problems in the two other groups. In all three groups, a normal motor examination at 1 and 5 years was highly predictive of normal motor skills at age 14.

Abstract
BACKGROUND Increased prevalence of motor and visual problems has been reported in low birth weight populations, but the association between them is less studied. AIM To examine how visual impairments may be associated with the increased risk of motor problems in low birth weight adolescents. METHODS Fifty-one very low birth weight adolescents (VLBW), 56 term small for gestational age (SGA) and 75 term control adolescents, without cerebral palsy, were examined at the age of 14. Motor skills were examined by the Movement Assessment Battery for Children. Visual functions included visual acuity, contrast sensitivity, nystagmus, strabismus, stereoacuity, accommodation, convergence and visual perception (Visual-Motor Integration test). An abnormality score was calculated as the sum of visual impairments. We used odds ratio as an estimate of the relative risk of having motor problems. RESULTS The odds of having motor problems were 10.4 (95% CI: 2.2-49.4) in the VLBW group and 5.1 (95% CI: 1.0-25.8) in the SGA group compared with the control group. The odds of having motor problems in the VLBW group were influenced by all visual variables, and most by visual acuity, when we adjusted for these separately. The greatest reduction in OR was found when adjusting for the abnormality score (adjusted OR: 6.8; 95% CI: 1.3-34.5). In the SGA group the odds of having motor problems were relatively unaffected by the visual variables and the abnormality score. CONCLUSIONS Visual impairments influence motor problems in VLBW adolescents, whereas motor problems in SGA adolescents seem to be unaffected by visual impairments.

Abstract
BACKGROUND High prevalence of abnormal cerebral MRI findings as well as major and minor motor, perceptual and cognitive impairments has been reported in very low birth weight (VLBW) children. AIM To investigate whether cerebral MRI pathology relates to different types of neuroimpairments in adolescents with VLBW. METHODS At age 15, 55 adolescents with birth weight < or = 1500 g (VLBW) were examined. Motor function was evaluated by Movement Assessment Battery for Children (ABC) and the Grooved Pegboard (GP) test, cognitive function by Wechsler Intelligence Scales, and visuo-motor and visual perceptual function by The Developmental Test of Visual-Motor Integration (VMI) with the supplementary tests of Visual Perception (VP), and Motor Coordination (MC). Executive functions were assessed by Wisconsin Card Sorting Test (WCST) and the Stroop test. Cerebral MRI was assessed semi-quantitatively for ventricular, white and grey matter pathology. RESULTS There was a rather weak relationship between MRI pathology and neuroimpairments. Poor performance on the WCST was related with ventricular dilatation (VD), white matter reduction and corpus callosum thinning. There was a correlation between results on the VMI test and the Movement ABC test and MRI pathology, but the correlation became much weaker when children with cerebral palsy were excluded. There was no relationship between MRI findings and estimated intelligence quotient (IQ) scores. Normal MRI predicted normal or near normal neuropsychological functioning. CONCLUSION Cerebral MRI pathology suggestive of perinatal white matter injury was related to disadvantages in performances on executive functions, to a lesser degree to motor and visual perceptual problems, but not to cognitive impairments in VLBW adolescents.

Abstract
BACKGROUND Very low birthweight (VLBW; birthweight <or=1,500 g) children run a greater risk than controls of developing neurosensory disabilities, but also minor neurological disturbances. AIMS To assess neurological status from the neonatal period up to fifteen years of age in VLBW children without overt neurological disability in relation to gender, neonatal risk factors, and magnetic resonance imaging (MRI) findings of the brain. STUDY DESIGN A population based follow-up study of VLBW children and their controls. SUBJECTS Eighty VLBW children without overt disability, in a cohort of 86 surviving VLBW children, were enrolled in a follow-up study at 40 weeks gestational age and at 4, 9, and 15 years of age. 56 VLBW children were examined with cerebral MRI at 15 years of age. OUTCOME MEASURES Neurological test scores. MRI findings, principally white matter damage (WMD). RESULTS VLBW children were inferior in neurological assessments in comparison with controls at 40 weeks gestational age and 4 and 15 years of age. VLBW girls did not differ from their controls at 9 and 15 years. Fourteen of 56 (25%) VLBW children had abnormal MRI findings and 13 were evaluated as mild WMD. Children with WMD did not differ in neurological outcome from those without WMD at any examination. Mechanical ventilation and/or intraventricular haemorrhage (IVH) during the neonatal period were significantly related to less a favourable outcome at follow-up examinations. CONCLUSION A cohort of VLBW children without overt neurological disability had a poorer neurological condition up to adolescence in comparison with controls. A quarter of the VLBW children had mild WMD but without relation to the neurological functions. Mechanical ventilation and IVH were related to poorer neurological outcome.

Abstract
PURPOSE To assess eye movements and binocular function in 14-year-olds with very low birthweight (VLBW: birthweight </= 1500 g) and 14-year-olds born at term but small for gestational age (SGA: birthweight < 10th percentile) in a population-based study. METHODS Ophthalmological examinations including measurements of heterophoria/tropia, near point of convergence, accommodative amplitude, stereopsis, nystagmus, saccades and smooth pursuit were performed in 51 adolescents with VLBW, 58 adolescents born SGA and in a control group consisting of 75 subjects of the same age. RESULTS Latent or manifest strabismus, poor stereopsis, poor convergence and nystagmus were all more frequent in the VLBW group than in the control group. The VLBW group did not differ from the control group regarding accommodative amplitude or saccades and smooth pursuit. The SGA population did not differ from the control group in the measured variables. CONCLUSIONS Premature birth with VLBW affects binocular visual functions negatively in adolescence, whereas birth small for date at term does not appear to be a risk factor for impaired eye movements and binocular function.

Abstract
Advances in perinatal technology that improved survival may have also resulted in prolonged death from the neonatal to the postneonatal period for some infants. The objectives of this study were to determine if the medical advances that occurred in the 1990s benefited infants of multiple births more than their singleton counterparts, and if these changes prevented or postponed mortality for the smallest and most immature infants. The study population included live births of 22 to 43 weeks' gestation from the 1989-1991 and 1999-2001 US Birth Cohort Linked Birth/Infant Death Data Sets. Odds ratios were calculated to evaluate the change in risk by plurality, gestation, and to compare the change to that for singletons. Neonatal and infant mortality rates declined for all pluralities; postneonatal mortality increased for births at less than 26 weeks, but declined at later gestations. In general, the risk of death for twins and triplets compared to singletons decreased, and the improvement in survival was greater for multiples during the early neonatal period and overall. Infant mortality rates improved by 28% for singletons, 32% for twins and triplets during the 1990s, although for the most premature infants, some deaths were postponed from the early to the late neonatal period.

Abstract
PURPOSE To assess visual acuity (VA), contrast sensitivity, visual fields, refractive errors and use of correction in adolescents with very low birthweight (VLBW; birthweight < 1500 g) and adolescents born at term but small for gestational age (SGA; birthweight < 10th percentile) in a population-based study. METHODS Ophthalmological examination including VA, Vistech contrast sensitivity and Humphrey two-zone, 120-point perimetry was performed in 51 VLBW, 59 SGA and 77 control adolescents. RESULTS The VLBW adolescents had reduced VA, reduced contrast sensitivity, and were more often anisometropic compared with control adolescents. They had started wearing glasses earlier, but were not more likely to use correction as teenagers. However, they were more often undercorrected (for refractive status) than control adolescents. Hypermetropia was more common in the SGA group than in the control group, but otherwise the SGA group did not differ from the control group. CONCLUSIONS Being born SGA may be a risk factor for hypermetropia in adolescence. Prematurely born adolescents present lower VA and contrast sensitivity and are more prone to anisometropia than adolescents born at term. It may be noteworthy that a higher proportion of VLBW than control adolescents were undercorrected, despite the well known vulnerability of visual function associated with preterm birth.

Abstract
Very low birth weight (VLBW) children are at high risk of perinatal white matter injury, which, when subtle, may not be seen using conventional magnetic resonance imaging. The relationship between clinical findings and fractional anisotropy (FA) measurements in white matter of adolescents born prematurely with VLBW was studied in 34 subjects (age = 15 years, birth weight </=1500 g) and 47 age-matched controls born at term, who were examined both clinically and with diffusion tensor imaging (DTI). Perceptual and cognitive functions were evaluated by visual motor integration (VMI) with supplementary tests and sub-tests from WISC-III, motor function by movement ABC and Grooved Pegboard test and psychiatric symptoms by the schedule for affective disorders and schizophrenia for school-age children semistructured interview, the Autism Spectrum Screening Questionnaire and attention deficit hyperactivity disorder (ADHD) rating scale IV. Overall functioning was scored on the children's global assessment scale. DTI scans were performed for calculation of FA maps and areas of significant differences in mean FA values between subjects and controls were compared with their clinical data. The VLBW children had reduced FA values in the internal and external capsule, corpus callosum and superior, middle superior and inferior fasciculus. Within this group of children, visual motor and visual perceptual deficits were associated with low FA values in the external capsule, posterior part of the internal capsule and in the inferior fasciculus. Children with low IQ had low FA values in the external capsule and inferior and middle superior fasciculus. Fine motor impairment was related to low FA values in the internal and external capsule and superior fasciculus. Eight VLBW children with inattention symptoms or a diagnosis of ADHD had significantly lower FA values in several areas. Mild social deficits correlated with reduced FA values in the external capsule and superior fasciculus. We conclude that DTI was able to detect differences in FA between VLBW adolescents and controls in several white matter areas at risk of periventricular leucomalacia in VLBW newborns. Our results show that low FA values in these areas were associated with perceptual, cognitive, motor and mental health impairments. These conclusions indicate that perinatal injury of white matter tracts persist with clinical significance in adolescence.

Abstract
This paper investigated the use of prospective control in catching and how the results can be used as a sensitive tool to detect diffuse signs of brain dysfunction. A detailed analysis of 286 catching movements of eight adolescents (two males, six females [four very-low-birth weight {VLBW}, one small for gestational age {SGA}, and three appropriate for gestational age]; mean age 14 y 5 mo [SD 6 mo]; range 14-15 y) was performed blind for this purpose. The moving target approached the participants from the side at three different, non-constant accelerations. The results showed that three adolescents used less advanced timing strategies that involved the lower-order variables of distance or velocity to govern movement initiation of at least one of their hands. Two of these were preterm VLBW and one was term SGA. The remaining adolescents, on the other hand, all relied on the higher-order variable of time-to-contact to initiate their hand movements, and were, therefore, considered low-risk. These results were compared with the cerebral magnetic resonance imaging results of the adolescents. The findings show that timing strategy pinpoints successfully those adolescents at risk of neurological problems. It was, therefore, concluded that the skill of using prospective information for catching can be used as a tool to detect diffuse signs of motor dysfunction, which are not readily detected by standard behavioural tests alone.

Abstract
BACKGROUND Motor problems in low birth weight children may be related to problems in sensorimotor integration processes. Specific tests of inter- and intra-modal matching have not been used in low birth weight populations. AIM Examine whether low birth weight adolescents have poorer performance in inter- and intra-modal matching than normal birth weight adolescents. STUDY DESIGN A population based follow up study of very low birth weight and small for gestational age children at 14 years of age. SUBJECTS Fifty-three very low birth weight adolescents (VLBW: birth weight < or =1500 g), 59 term small for gestational age (SGA: birth weight <10th centile) and 82 adolescents with birth weight > or =10th centile at term (reference group). OUTCOME MEASURES Inter- and intra-modal matching was assessed by a manual matching task and results were presented for the preferred and the non-preferred hand in the visual (inter-modal) and proprioceptive (intra-modal) condition. RESULTS VLBW adolescents performed poorer in inter- and intra-modal matching compared with the reference group. However, the results were mainly due to a higher number of adolescents with cerebral palsy (CP) and a low estimated intelligence quotient (IQ(est)) in the VLBW group. SGA adolescents showed poorer performance with their non-preferred hand compared with their preferred hand in both inter- and intra-modal matching, whereas adolescents in the reference group and VLBW adolescents with normal IQ(est) and without CP performed equally well with both hands. CONCLUSION VLBW adolescents with normal IQ(est) and without CP do not have major problems in inter- and intra-modal matching. The poorer performance with the non-preferred hand in the SGA group may suggest a specific effect of intrauterine growth retardation.
