Abstract
Childhood bereavement is an adverse event, yet children demonstrate considerable variability in health outcomes. Bereaved children are at risk of lower lifelong educational attainment, though the contribution of neurocognitive performance is yet to be investigated. Using data from the population-based Generation R Study wherein nearly 10,000 pregnant mothers were recruited between 2002 and 2006, we estimated the association of bereavement by age 10 years with four subtests of cognitive function and academic achievement at 13 years. Bereavement by 10 years of age was experienced by n = 796 (37.3%) of youth and was associated with a 1.12-point (SD = 0.55; p-value = 0.04) lower full-scale IQ at 13 years, which was mainly driven by lower matrix reasoning scores (β(adjusted) = -0.27, SE = 0.11, p < 0.02). There were no differences in academic achievement or other subtests of neurocognitive function between bereaved and non-bereaved children. Secondary analyses adjusting for pre-bereavement nonverbal cognitive ability and mental health problems revealed an overall association between bereavement and subsequent full-scale IQ and matrix reasoning, but only among those youth whose caregivers reported that the loss had an emotional influence on the child. These novel findings leveraging prospective assessments in a population-based birth cohort highlight risk and resilience mechanisms warranting further research.
