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

Mentions: Children in both studies were administered a Mathematics Estimation Test9,27 at age 8 (BLS) and 11 (EPICure) years, respectively. Tasks were presented to children in book form with 12 items assessing the estimation of dot array and number line magnitude, as well as judgments of approximate length and distance (Figure 1; available at www.jpeds.com). Item responses were scored for accuracy and summarized into a total score. Test scores were standardized based on term controls in each study separately (standardized control mean 100; SD 15).
