Abstract
This study will examine whether maternal vitamin D deficiency is a risk factor for infantile autism disease (IAD). I used epidemiologic data seasonal variation of birth rates and prevalence of IAD for cohorts born before 1985. For seven studies reporting spring-to-summer excess birth rates for IAD, the season progressed from broad near 30° N latitude, spring/summer in midlatitudes, to winter at the highest latitude. Also, using data from 10 studies, I found a strong effective latitudinal (related to solar ultraviolet B radiation) increase in IAD prevalence. These findings are consistent with maternal vitamin D deficiency’s being a risk factor for IAD, a factor affecting immune system status.
