    AIM: To assess the predictive validity at 4 years of the Movement Assessment Battery for Children - Second Edition (MABC-2) for motor impairment at 8 years in children born preterm. We also aimed to determine if sex, cognition, medical, or social risks were associated with motor impairment at 8 years or with a change in MABC-2 score between 4 years and 8 years. METHOD: Ninety-six children born at less than 30 weeks' gestation were assessed with the MABC-2 at 4 years and 8 years of age. Motor impairment was defined as less than or equal to the 5th centile. The Differential Ability Scales - Second Edition (DAS-II) was used to measure General Conceptual Ability (GCA) at 4 years, with a score <90 defined as 'below average'. RESULTS: There was a strong association between the MABC-2 total standard scores at 4 years and 8 years (59% variance explained, regression coefficient=0.80, 95% confidence interval [CI] 0.69-0.91, p<0.001). The MABC-2 at 4 years had high sensitivity (79%) and specificity (93%) for predicting motor impairment at 8 years. Below average cognition and higher medical risk were associated with increased odds of motor impairment at 8 years (odds ratio [OR]=15.3, 95% CI 4.19-55.8, p<0.001, and OR=3.77, 95% CI 1.28-11.1, p=0.016 respectively). Sex and social risk did not appear to be associated with motor impairment at 8 years. There was little evidence that any variables were related to change in MABC-2 score between 4 years and 8 years. INTERPRETATION: The MABC-2 at 4 years is predictive of motor functioning in middle childhood. Below average cognition and higher medical risk may be predictors of motor impairment.

    Neurobehaviour at term-equivalent age and neurodevelopmental outcomes at 2 years in infants born moderate-to-late preterm
    Spittle, AJ ; Walsh, JM ; Potter, C ; Mcinnes, E ; Olsen, JE ; Lee, KJ ; Anderson, PJ ; Doyle, LW ; Cheong, JLY (WILEY, 2017-02)
    AIM: To examine the association between newborn neurobehavioural assessments and neurodevelopmental outcomes at 2 years in infants born moderate-to-late preterm (MLPT). METHOD: Two-hundred and one infants born MLPT (born 32-36+6 wks' gestation) were assessed with the Hammersmith Neonatal Neurological Examination (HNNE) and NICU Network Neurobehavioral Scale (NNNS), with suboptimal performance defined as scores lower than the 10th centile. Development was assessed at 2 years corrected age with the Bayley Scales of Infant and Toddler Development 3rd Edition, with delay defined as scores less than 1 standard deviation (SD) below the mean. The relationships between neurobehaviour at term and Bayley-III cognitive, language, and motor scales at 2 years were examined using linear regression. RESULTS: Increased odds for cognitive delay were associated with suboptimal HNNE total scores (odds ratio [OR] 2.66; 95% confidence interval [CI] 1.14-6.23, p=0.020) and suboptimal NNNS excitability (OR 3.01; 95% CI 1.33-6.82, p=0.008) and lethargy (OR 4.05; 95% CI 1.75-9.31, p=0.001) scores. Suboptimal lethargy scores on the NNNS were associated with increased odds of language (OR 5.64; 95% CI 1.33-23.85, p=0.019) and motor delay (OR: 6.86; 95% CI 1.64-28.71, p=0.08). INTERPRETATION: Suboptimal performance on specific aspects of newborn neurobehavioural assessments is associated with neurodevelopmental delay at 2 years in children born MLPT.
