Figure 3

Events related to infant feeding and the prevalence of autism. The data on the number of cases of children with autism in the 1980–1994 birth cohorts in California are taken from [13]. Note that the implementation the Infant Formula Act of 1980 [51] was followed by an apparent increase in autism incidence, while the advertising of infant formula to the general public, started in 1988, was accompanied with a rapid increase in the incidence of autism. The increases were greatest for annual cohorts born from 1987 to 1992.
