Autism prevalence is reported to be highest among non-Hispanic white children, lower in Hispanic and African American/black children, and highly variable in Asian/Pacific Islanders. More comorbid intellectual disability and delays in expressive language have been observed among Hispanic and African American children.
The country with the highest rate of diagnosed autism in the world is Qatar, and the country with the lowest rate is France. Around 4 times as many boys have autism as girls. The rate of autism in the U.S. went from 1 in 150 in 2000 to 1 in 100 in 2022.
ASD affects people of all races and ethnicities, but research shows that African-American and Latino children with autism are diagnosed at older ages than white children, giving them less of an opportunity for proper intervention and treatment.
ASD occurs in all racial, ethnic, and socioeconomic groups. It is more than 4 times more common among boys than among girls.
It is also common for autistic individuals to be called metaphorically as 来自星星的孩子 (translation: "children from the star"). Autism has a prevalence rate of around 1% among the Chinese population.
It is estimated that 1 in 100 people in Australia have Autism. In 2018 there were 205,200 Australians with Autism, a 25.1% increase from the 164,000 in 2015 (Source: ABS SDAC 2018– Autism in Australia). This means that if you have Autism you are not alone.
Advances in diagnostic capabilities and greater understanding and awareness of autism spectrum disorder seem to be largely driving the increase, the Rutgers researchers said. But there's probably more to the story: Genetic factors, and perhaps some environmental ones, too, might also be contributing to the trend.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Autism is not caused by malnutrition or food-related challenges, but, for many people, there is a connection between autism and food. Research suggests that food-related challenges have a significant impact on many people who are diagnosed on the autism spectrum.
Genetic causes of autism
Many experts believe genes play the biggest role in causing autism.
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).
Inheritance. ASD has a tendency to run in families, but the inheritance pattern is usually unknown. People with gene changes associated with ASD generally inherit an increased risk of developing the condition, rather than the condition itself.
Globally, the World Health Organization estimates that the prevalence of autism spectrum disorder (ASD) is one per 160 children. The prevalence in the Middle East is still unknown, largely due to a lack of diagnoses or a lack of acceptance from parents.
Research shows that autism can indeed run in families. If you already have one child with ASD, you have a 1 in 5 chance of your next child developing autism. If you have more than one child with ASD, the odds of having another child with ASD are even higher.
Einstein himself had many autistic traits. He did not learn to speak until he was three, and he had a lack of concern about his appearance.
Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
According to a study published in Molecular Autism, children born to mothers with autism have a 5.4% chance of also being diagnosed with the disorder, while children born to fathers with autism have only a 1.5% chance.
While you can't prevent having a child with an autistic disorder, you can increase your odds of having a healthy baby by doing these lifestyle changes: Live healthy. Have regular check-ups, eat well-balanced meals, and exercise. Make sure you have good prenatal care, and take all recommended vitamins and supplements.
“Firstborn offspring of two older parents,” Durkin's study noted, “were three times more likely to develop autism than were third- or later-born offspring of mothers aged twenty to thirty-four and fathers aged under forty years.”
It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life. Autism is not a medical condition with treatments or a "cure".
Increased availability of services.
Over the years, services for autism have become more readily available. The availability of services has encouraged more people to seek a diagnosis in order to gain access to these services.
Centrelink. Centrelink, managed by the Australian Government Department of Human Services, delivers a range of payments for children or adults with autism, or caring for people with autism.
