Demographic and autism characteristics as predictors of age of autism diagnosis of individuals with autism in Paraguay.

Kaori and colleagues asked caregivers in Paraguay about their children with autism.

They wanted to know what makes diagnosis happen sooner or later.

Parents filled out a survey about the child’s age, first worries, and talking level.

Kids got diagnosed earlier when parents first worried sooner.

Children who could speak words were also diagnosed earlier.

Older kids at the time of the study had waited longer for a label.

Mathur et al. (2025) extends these findings. They show U.S. toddlers with autism face extra barriers like food or housing gaps. Together the papers say: social factors plus child traits steer when diagnosis happens.

Hatton et al. (2004) is a predecessor. That team proved autism can be spotted reliably by age 2. Kaori et al. now show what speeds or slows that moment in a lower-resource country.

Norrelgen et al. (2015) adds a twist. One in four preschoolers still lack phrase speech after two years of help. Kaori links early words to earlier diagnosis, but Fritjof reminds us some kids remain non-verbal despite later services.

If you coach families, ask early about first worries and note any words the child uses. Flag these points to doctors right away. In rural or low-resource areas this simple push can shave months off wait time and start help sooner.
