ABSTRACT
BACKGROUND: In utero exposure to maternal cancer and cancer treatment might influence the child’s cognitive development. This study investigated if exposure to maternal cancer during fetal life impacted school performance and educational achievement as adults.
METHODS: This nationwide retrospective cohort study identified all live-born children in Denmark between January 1978 and December 2013. Exposure was defined as maternal cancer diagnosis during pregnancy. Four partly overlapping birth cohorts were constructed depending on the outcome of interest: (1) receiving special educational support for birth years 2001-2013; (2) grade point average (GPA) at the final exams after 10th grade for 1986-2003; (3) educational achievement at 20 years for 1978-1998; and (4) education at 30 years for 1978-1988. Logistic and linear models were adjusted for birth year, maternal age, maternal education and maternal death.
RESULTS: The estimated probability of receiving special educational support was similar in the exposed group and the reference (adjusted OR 0.96; 95% CI 0.46 to 1.77, non-significant). The GPA did not statistically differ (0.13 grade points; 95% CI -0.18 to 0.45, non-significant). The achieved educational levels were similar for the exposed group and the reference at 20 years, with an adjusted OR of 1.07 (95% CI 0.82 to 1.40) for low versus medium educational level, and at 30 years with an adjusted OR of 0.73 (95% CI 0.35 to 1.50) for low versus high educational level and of 1.07 (95% CI 0.66 to 1.72) for medium versus high educational level.
CONCLUSION: Our findings did not indicate poorer performance in compulsory school nor impairment of adult educational achievement after exposure to maternal cancer in utero.
