Developmental coordination disorder at 8 years of age in a regional cohort of extremely‐low‐birthweight or very preterm infants

Abstract

The aims of this study were to determine the motor outcome of extremely-low-birthweight (ELBW; <1000g) or very preterm (<28wks) children compared with normal birthweight (NBW) children, to establish the perinatal associations of developmental coordination disorder (DCD) and its cognitive and behavioural consequences. Participants were consecutive surviving ELBW or very preterm children and randomly selected NBW(>2499g) children born in the state of Victoria, Australia, in 1991 or 1992. Main outcomes were: (1) results of the Movement Assessment Battery for Children (MABC) at 8 years of age; (2) cognitive function; (3) academic progress; and (4) behaviour. Of 298 consecutive ELBW/very preterm survivors, 255 (85.6%; 117 males, 138 females) had the MABC at a mean age of 8 years 8 months. More ELBW/very preterm children (9.5%) had DCD than the NBW group (2%, p=0.001). Only male sex increased the likelihood of DCD in ELBW/very preterm children (p=0.017). ELBW/very preterm children with DCD had worse cognitive function and academic test scores (up to 1SD below those without DCD); they also had more adaptive behaviour and externalizing problems, but not internalizing problems. DCD is more common in ELBW/very preterm children, has few perinatal correlates, and is associated with poor cognitive and academic performance as well as increased behaviour problems.

School readiness of moderately preterm children at preschool age

“…Children involved in the research project compared to the control group would seem to be characterized by social orientation, collaboration, and interaction abilities, which give them the chance to be extrovert and to activate exchanges and build relationships, which can also assure them the development of the abilities that they lack. These data are consistent with some studies of the field (Davis et al 2007;Gray et al 2008;Manjemer et al 2000;Winchester et al 2009;Ketharanathan et al 2011;Perricone & Morales 2011a, b;Perricone et al 2012a, b). These are abilities that can support the social success and scholastic contextualization of preterm children.…”

Educational Outcomes in Extremely Preterm Children: Neuropsychological Correlates and Predictors of Attainment

“…Studies of school-age survivors have highlighted a significant excess of mild neuromotor dysfunction (Davis, Ford, Anderson, & Doyle, 2007;Fawke, 2007;Goyen & Lui, 2009;Wocadlo & Rieger, 2008), poor visuospatial processing (Marlow, Hennessy, Bracewell, & Wolke, 2007;Taylor, Burant, Holding, Klein, & Hack, 2002;Taylor, Klein, Minich, et al, 2000), and impairments in attention and executive functions (Aarnoudse-Moens, Smidts, Oosterlan, Duivenvoorden, & Weisglas-Kuperus, 2009; Anderson & Doyle, 2004;B. Bohm, Smedler, & Forssberg, 2004;Marlow et al, 2007;Mulder, Pitchford, Hagger, & Marlow, 2009).…”

Baixo peso ao nascer e proficiência motora em crianças: uma revisão sistemática

“…De fato, alguns outros fatores (idade gestacional, milleu hormonal, desnutrição, tabagismo, fármacos) durante a gestação podem também induzir a prematuridade e repercutir em deficit motor ao longo do desenvolvimento 1, 16,17 . Contudo, o presente estudo tem como objetivo focar a relação existente entre o baixo peso ao nascer e o desenvolvimento motor.…”
