Birth seasonality in developmentally disabled children.
26 children with diagnoses of autism and 22 children with diagnoses of childhood schizophrenia or a variant thereof were compared on the variable of winter birth. Analyses showed that autistic children had a higher proportion of winter births than schizophrenic children. These findings are related to other research linking winter birth to negative-syndrome adult schizophrenia.
