New York: Children born to teenage mothers and whose parents have a large gap between their ages, are at an increased risk of developing Autism Spectrum Disorder (ASD), says a large study involving 5.7 million children in five countries.

The study also confirmed that older parents are at higher risk of having children with ASD, which is characterised by social avoidance, repetitive behaviours and difficulty in communicating.

“When we first reported that the older age of fathers increases risk for autism, we suggested that mutations might be the cause. Genetic research later showed that this hypothesis was correct,” said study co-author, Abraham Reichenberg, neuropsychologist and epidemiologist with the Icahn School of Medicine at Mount Sinai, New York City.

“In this study, we show for the first time that autism risk is associated with disparately-aged parents. Future research should look into this to understand the mechanisms,” Reichenberg noted.

The study, published in the journal Molecular Psychiatry, looked at autism rates among 5,766,794 children — including more than 30,000 with autism — in Denmark, Israel, Norway, Sweden and Western Australia.

The children were born between 1985 and 2004, and the researchers followed up on their development until 2009, checking national health records for autism diagnoses.

Autism rates were 66 percent higher among children born to fathers over 50 years of age, than among those born to fathers in their 20s. Autism rates were 28 percent higher when fathers were in their 40s versus 20s.

Autism rates were 15 percent higher in children born to mothers in their 40s, compared to those born to mothers in their 20s.

Autism rates were 18 percent higher among children born to teenage mothers than among those born to mothers in their 20s.

Autism rates rose still higher when both parents were older, in line with what one would expect if each parent’s age contributed to risk.

Autism rates also rose with widening gaps between two parents’ ages. These rates were highest when fathers were between 35 and 44 and their partners were 10 or more years younger.

“These results suggest that multiple mechanisms are contributing to the association between parental age and ASD risk,” the authors concluded. (IANS)

EMI is known as equated monthly installments. It is a fixed payment made by the borrower each month to repay the loan amount. The EMI is divided into two loan components. One is the principal amount, and the second is the interest amount. Whether you are applying for a personal loan, business loan, home loan, car loan, or education loan, EMIs are easy to calculate using the EMI loan calculator.

Swastika, one of the sacred symbols used by many religions like Hinduism, Jainism, and Buddhism.

The symbol of Swastika is known to signify peace, prosperity, and good fortune in the religious cultures of Eurasia. In fact, this symbol is considered very significant in Hinduism, Buddhism, and Jainism. But, at the same time, it has become one of the most misunderstood religious symbols and has been globally banned in many countries.

The reason why the symbol of Swastika is banned in many countries is because of its association with Adolf Hitler's extreme political ideology, Nazism, as Swastika as its official symbol.

Since emerging into the public eye with a historic gold medal at the junior world championships in 2016, he has maintained a high level of performance

India celebrated a historic day on August 7, as 23-year-old Neeraj Chopra became the first Indian to win an Olympic gold medal in athletics. In the men's javelin throw event, he achieved his greatest triumph, throwing the javelin 87.58 meters on his second try.

Neeraj Chopra was born on December 24, 1997, in Khandra village in Haryana's Panipat district. He grew up in a Haryanavi family of farmers. He is the brother of two sisters. He graduated from Dayanand Anglo-Vedic College in Chandigarh and is now enrolled in Lovely Professional University in Jalandhar, Punjab, pursuing a Bachelor of Arts degree. Chopra was bullied due to his obesity as a kid, which prompted his father to enroll him in a nearby gym. He then joined a gym in Panipat, where Jaiveer Choudhary, a javelin thrower, noticed his potential and coached him. When the 13-year-old Chopra finished training under Jaiveer for a year, he was enrolled at the Tau Devi Lal Sports Complex in Panchkula, where he began training under coach Naseem Ahmed.
