Developmental coordination disorder at 8 years of age in a regional cohort of extremely‐low‐birthweight or very preterm infants
2007
The aims of this study were to determine the motor outcome of extremely-low-birthweight (ELBW; 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.
