Jen Chen, our guest lecturer, posed the question of whether there is an ASD epidemic and showed some prevalence figures to illustrate her point. Which of the following is accurate about the estimated prevalence of ASD based on the Autism Prevalence Graph shown in lecture?

B. ASD prevalence is 4x more likely in girls than boys: 1 in 37 females
C. The prevalence of ASD in recent years is currently 1 in 59
D. All of the above

Answer 1

The accurate statement about the estimated prevalence of ASD is that in recent years it is currently 1 in 59.

Step-by-step explanation:

The accurate statement about the estimated prevalence of Autism Spectrum Disorder (ASD) based on the Autism Prevalence Graph shown in the lecture is option C: The prevalence of ASD in recent years is currently 1 in 59.

The lecture showed that in 2004, the prevalence was about 1 case of ASD per 600 children, not 1 in 600. Option A is incorrect.

ASD prevalence is not 4 times more likely in girls than boys. It is actually four times more prevalent in boys than in girls. Option B is incorrect.

Therefore, option D, 'All of the above,' is incorrect. The accurate statement is option C, which states that the prevalence of ASD in recent years is currently 1 in 59.
