CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Conclusion: Of children meeting criteria for ASD, the true male-to-female ratio is not 4:1, as is often assumed; rather, it is closer to 3:1. There appears to be a diagnostic gender bias, meaning that girls who meet criteria for ASD are at disproportionate risk of not receiving a clinical diagnosis.

Detailed explanation-2: -A substantial amount of research shows a higher rate of autistic type of problems in males compared to females. The 4:1 male to female ratio is one of the most consistent findings in autism spectrum disorder (ASD).

Detailed explanation-3: -The extreme male brain theory posits that it is an overdevelopment in the male traits of cognition that causes ASD patients to over-systematize, leading to a breakdown of verbal and social capacities. Some studies have found correlations between fetal testosterone levels and ASD.

Detailed explanation-4: -Various studies suggest that the ratio of autistic males to females ranges from 2:1 to 16:1. The most-up-to-date estimate is 3:1. In Leo Kanner’s 1943 study of a small group of autistic children, there were four times as many boys as girls.

Detailed explanation-5: -The prevalence ratio is often cited as about 4 males for every 1 female diagnosed. Other research indicates that it closer to 3:1 or 2:1. One in every 42 males and one in 189 females in the United States is diagnosed with autism spectrum disorder.
