N2 - AIM: We investigated the associations between motor performance and IQ at 5 years of age and school difficulties and grade point averages (GPAs) at 18 years of age. Additionally, the accuracy of preschool IQ in predicting school difficulties was examined.METHODS: A nationwide follow-up study of children born in 1994-1995 who were <28 weeks of gestation or had a birthweight <1000 g. The Danish personal identification number was used to merge data from a national cohort study with population-based registries. Logistic regression analyses examined the associations between motor performance/IQ and school difficulties. Linear regression analyses and the area under the receiver operator curve (AUC) were used to examine the relationship between IQ and GPAs.RESULTS: The study population comprised 248 children, 37% were classified with school difficulties. Motor performance and IQ were associated with school difficulties. The odds of having school difficulties increased as IQ decreased, and the same pattern was observed for GPAs. IQ predicted school difficulties, with an AUC of 0.80 (confidence interval: 0.74-0.86).CONCLUSION: Preschool motor performance and IQ were associated with school difficulties. Additionally, IQ was linked to GPAs. As a screening tool, the predictive ability of preschool IQ for academic difficulties was moderate/high in this cohort.
