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)

Lack of Proper Sanitation Affects 620 Million Children Around The World: Report

Despite the improvements, more than a third of the girls in South Asia miss school for one to three days a month during their period.

A lack of proper school toilets threatens the health, education and safety of at least 620 million children around the world, the charity WaterAid said in a new study published Friday.

Children at 1 in 3 schools lack access to proper toilets, putting them at risk of diarrhea and other infections and forcing some to miss lessons altogether, according to the study, based on data from 101 countries.

Guinea-Bissau in West Africa has the worst school toilets while Ethiopian children fare worst at home, with 93 percent of homes lacking a decent toilet according to the report, released ahead of World Toilet Day on Monday.

“The message here is that water and sanitation affect everything,” WaterAid spokeswoman Anna France-Williams told the Thomson Reuters Foundation. “If there’s no toilet in schools, children will miss lessons and it will have an impact on their growing up.”

Diarrhea, infection risk

A lack of proper sanitation puts millions of children around the world in danger of diarrhea, which kills 289,000 children younger than 5 a year, WaterAid said.

But some regions have started to clean up their act, notably South Asia, where access to toilets in schools has improved.

More than half the schools in Bangladesh now have access to decent toilets, while students in 73 percent of schools in India and 76 percent of those in Bhutan can access basic sanitation.

Akramul Islam, director of water, sanitation and hygiene at the Bangladeshi charity BRAC, said the country’s once-high levels of open defecation — using open ground rather than toilets — were now less than 1 percent.

“Today, schools have separate toilets for girls and boys and the issue of menstrual hygiene is also being addressed,” he said. “This has happened because of initiatives taken by both the government, the NGOs and other stakeholders.”

Improvement needed

Despite the improvements, more than a third of the girls in South Asia miss school for one to three days a month during their period, WaterAid said, urging greater investment in basic sanitation.

“If we are serious about all children and young people, wherever they are, whatever their gender, physical ability or community background, having their right to clean water and sanitation, we must take decisive and inclusive action now,” said Chief Executive Tim Wainwright. (VOA)
