Healio (4/15, Gramigna) reports investigators “have reported additional evidence suggesting an independent association between advanced parental age and increased risk for autism spectrum disorder [ASD] among offspring.” For the study, researchers used “data from Danish national health registries” to construct “a parental age cohort to evaluate the relationship of parental age and ASD among 1,476,783 singleton children born from 1990 to 2013,” then “also constructed a multigenerational cohort that included 362,438 fathers and 458,234 mothers born from 1973 to 1990 for whom grandparental age data were available.” The findings of the “population-based, multigenerational cohort study” were published online April 15 in JAMA Network Open.
