Academic Impairment in Children Born Very Preterm at 7 and 13 Years of age.

Abstract

Objective: Children born very preterm (VPT) are vulnerable to academic challenges; however, it remains unclear whether these difficulties persist into early adolescence. This study aimed to investigate rates of academic impairment in children born VPT and full-term, and impairment stability from 7 to 13 years in children born VPT using 2 approaches: academic underachievement and IQ-achievement discrepancy.

Method: Participants were children born <30 weeks' gestational age and/or <1250 g and full-term (≥37 weeks' gestational age) assessed at 7 (VPT n = 197, full-term n = 69) and 13 years (VPT n = 179, full-term n = 61) on general cognitive ability (WASI-4 and KBIT-2), word reading, spelling, and mathematics (WRAT-4).

Results: Using an underachievement approach, children born VPT were more likely to have an academic impairment at ages 7 and 13 years compared with term-born controls, particularly in reading (odds ratio [OR] and confidence interval [CI] at 7 years: 3.72 [1.67-8.27], at 13 years: 2.55 [1.06-6.11]) and mathematics (OR [CI] at 7 years: 5.77 [2.51-13.25], at 13 years: 2.78 [1.36-5.69]). Rates of impairment were low for both groups using an IQ-achievement discrepancy approach, although a group difference was evident for mathematics impairment at 7 years (OR [CI] 5.94 [1.37-25.8]), with higher rates in the VPT group (15% vs 3%). Rates of academic impairment remained relatively stable between 7 and 13 years of age, regardless of the approach applied.

Conclusion: The rate of academic impairment varies depending on the approach used to classify impairment. Our findings suggest that academic difficulties in children born VPT may reflect a general cognitive impairment rather than a specific academic deficit.
