Universal gestational age effects on cognitive and basic mathematic processing: 2 cohorts in 2 countries.

Wolke D, Strauss VY, Johnson S, Gilmore C, Marlow N, Jaekel J - J. Pediatr. (2015)

Bottom Line: The prediction function generated using BLS data accurately predicted the effect of GA on IQ and mathematic processing among EPICure children.The ability to predict IQ and mathematic processing scores from one cohort to another among children cared for in different eras and countries suggests that universal neurodevelopmental factors may explain the effects of gestation at birth.In contrast, mathematic attainment may be improved by schooling.

EPICure Study observed score distributions (box plotsāˆ—) with predicted mean scores (solid lines) and 50% (dashed lines) and 75% (dotted lines) prediction intervals based on the BLS cohort. Precision of prediction was examined by calculating the percentiles of box plots within prediction intervals and show that observed IQ and basic mathematic processing scores were mostly covered within the 50% prediction interval. āˆ—The bottom and top of each box are the 25th and 75th percentiles of observed scores, respectively. The line in the middle is the 50th percentile and hollow circles are observed mean scores.

The line in the middle is the 50th percentile and hollow circles are observed mean scores.

Mentions: Accuracy of predicted IQ, mathematic processing, and mathematic attainment scores for EP children was evaluated by inserting their observed scores into the piecewise regressions fitted to the BLS sample. FigureĀ 3 shows distributions of EPICure Study children's observed scores (box plots) vs their predicted scores (lines) with 50% and 75% prediction intervals based on the BLS data. Both observed IQ and basic mathematic processing scores between 25th and 75th percentiles were mostly covered within the 50% prediction interval (FiguresĀ 3 and 4; FigureĀ 4 available at www.jpeds.com), showing observed and predicted scores by GA in both BLS and EPICure children. Thus, consistent with hypothesis 1, BLS children's scores (27-41Ā weeksĀ GA) allowed accurate prediction of IQ and basic mathematic processing scores of children born at 23-25Ā weeksĀ GA in another country one decade later.
