Elevated pesticide levels in pregnant women are associated with an increased risk of autism among their children, says a study.

Autism is a complex neurodevelopmental disorder with largely unknown causes. It is characterised by problems with communication, difficulty relating to people and events, and repetitive body movements or behaviours.


“These findings provide the first biomarker-based evidence that maternal exposure to insecticides is associated with autism among offspring,” the researchers said.

The study, published online in the American Journal of Psychiatry, examined whether elevated maternal levels of persistent organic pollutants are associated with autism among children.

Persistent organic pollutants are toxic chemicals that adversely affect human health and the environment around the world.

The researchers, including Professor Alan Brown from Columbia University Medical Centre in the US, analysed levels of DDE, a breakdown product of the pesticide DDT (dichlorodiphenyltrichloroethane).

Although DDT and other persistent organic pollutants were widely banned in many countries decades ago, they persist in the food chain, resulting in continuous exposure among populations.

These chemicals transfer across the placenta, resulting in potential prenatal exposure among nearly all children.

The researchers evaluated levels of DDE in maternal serum samples drawn from more than 750 children with autism and matched control participants from a national birth cohort study, the Finnish Prenatal Study of Autism.

The odds of autism among children were significantly increased in mothers whose DDE levels were elevated (defined as the 75th percentile or greater).

In addition, the odds of children having autism with intellectual disability were increased more than twofold with maternal DDE levels above this threshold, the study said. (IANS)

Children playing ringa ringa roses in an open backyard in England

Great historic events that have shaped the world and changed the outlines of countries are often not recorded in memory, or so we think. Wars made sure to destroy evidence and heritage, and the ones who survived told the tale of what really happened. Folklore, albeit through oral tradition kept alive many such stories, hidden in verse, limericks, and rhymes.

Ringa-ringa-roses, a common playtime rhyme among children across the world, is an example of folklore that has survived for many centuries. It tells the story of the The Great Plague of London which ravaged the city between 1665-1666.

Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.

In modern times, many social movements aim to bring reform to the society we live in, on the basis of certain existing patterns. Patriarchy is something that many aim to cleanse our cultures of, to usher in the era of social and gender equality. Despite all these so-called movements, in southern India, certain societies that patronise matriarchy have existed since before India's independence. The Nairs and Ezhavas of Kerala, and Bunts and Billavas of Karnataka are matrilineal societies that continue to thrive in a patriarchal country.

Kerala remains separate from the rest of India in many ways. Be it literacy policy, form of government, or cultural practices, this state does not always conform to the ideal that India is known for. Even so with their social structure. Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.
