1240: Autism Rates Appear To Be Even Across Sexes. Diagnosis Is Not

from Science Friday · host Science Friday

There’s a long-held idea that autism is more prevalent in boys than girls—the CDC says it’s three times as common. But a growing body of research suggests the reality is more complicated. In a new study, researchers tracked autism diagnoses in millions of Swedish people born from 1985 to 2022. They found that the prevalence of autism is actually pretty even across the sexes, but people with “female” stamped on their birth certificate are often diagnosed later in life. Host Flora Lichtman speaks with epidemiologist Caroline Fyfe about what this study teaches us about the prevalence of autism. Then, psychology researcher Rachel Moseley, an autistic woman herself, shares how late and missed diagnoses can affect autistic people. Guests: Dr. Caroline Fyfe is an epidemiologist at the University of Edinburgh who studied sex differences in autism diagnoses.  Dr. Rachel Moseley is a researcher in psychology at Bournemouth University in the UK, studying the experiences of autistic adults.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
