The number of young people living with autism spectrum disorder is growing rapidly.

A new study has revealed a nearly 52% spike in autism spectrum disorder prevalence among children and teens in the US between 2017 and 2020.

Now, one in every 30 kids will be diagnosed with the developmental disorder, which presents a range of behavioral and cognitive symptoms.

The findings from public health researchers at Guangdong Pharmaceutical University in China were published in JAMA Pediatrics Monday.

Study authors did not discuss potential causes for the stark rise, though many experts have attributed the increase to greater awareness of the condition among parents and doctors.

Using data from the annual National Health Interview Survey, conducted by the US Centers for Disease Control and Prevention, researchers showed that figures have risen gradually since 2014, with a dip in cases between 2016 and 2017, then trending steadily upward again by 2020.
