Very‐low‐birthweight and term small‐for‐gestational‐age adolescents: Attention revisited

Aim: To assess whether adolescents with very low birthweight (VLBW) and peers born small for gestational age (SGA) at term are at a disadvantage when attending to or executing tasks. Methods: Cohorts of 54 VLBW (≤1500 g), 60 SGA and 83 controls were tested with the Knox Cube Test, Conners’ Continuous Performance Test (CPT II), Stroop Colour‐Word Test, Trail Making Test (TMT) A & B, and Wisconsin Card Sorting Test (WCST). IQ was estimated using the subtests vocabulary and picture arrangement of WISC III. Results: VLBW adolescents scored worse than controls on Knox Cube Test, Stroop Colour‐Word Test, TMT A & B and WCST, whereas term SGA adolescents only made more non‐perseverative errors in WCST and more errors in the interference condition of the Stroop Colour‐Word Test. Thirty‐two (38.6%) adolescents in the control group had poor performance (< 2 SD) on at least one of the tests compared with 40 (74.1%) VLBW (p<0.01) and 32 (53.3%) SGA adolescents (not significant).
