Get your children out of HK
(copied from the UK Daily Mail)
Could ADHD be triggered by mothers being exposed to air pollution while pregnant?
Scientists at Columbia University found children exposed to high levels of air pollution during pregnancy are five times more likely to have ADHD
Children exposed to high levels of pollution in the womb are at greater risk of suffering attention deficit hyperactivity disorder, a new study has found.
Scientists at Columbia University studied 233 non-smoking pregnant women living in New York.
They found children exposed to high levels of air pollution during pregnancy were five times more likely to have ADHD by the time they were nine years old.
The nine-year study looked at levels of common pollutants polycyclic aromatic hydrocarbons (PAH).
Researchers measured the levels of PAH in maternal and umbilical cord blood shortly after delivery.
And they repeated tests when each of the children were three and five, measuring levels of PAH in their urine.
Thirty-three children who had high levels of exposure to PAHs, as measured at birth.
Of those, 13 were diagnosed with ADHD hyperactive-impulsive subtype, seven the inattentive subtype, and 13 had both.
Professor Frederica Perera, first author of the study, said: 'Those children born to moms who were exposed to high levels of PAH during pregnancy had five times the odds of having an increased number of symptoms.'
PAHs are created when products like coal, oil, gas and rubbish are burned but not completely.
They don't burn easily, and as a result remain in the environment for long periods of time.
Most are used to conduct research though some are used to make dyes, plastics and pesticides.
One of the most common ways they enter the body is through breathing in contaminated air.
To establish children's exposure to PAHs in the womb, the scientists measured levels of fragments of the mothers' DNA bonded to PAH molecules, also known as DNA adducts, in umbilical cord blood.
Previous studies carried out by Professor Perera and her team identified links between higher levels of prenatal PAH exposure and developmental delays in children by the age of three.
They also noted lower IQ scores at five, and increased risk a child will suffer anxiety, depression and attention problems at six and seven.
The new study, published in the journal PLoS One, looked at the children's ADHD symptoms using the Child Behavior Checklist and the Conners' Parent Rating Scale - two screening tests used to diagnose the condition.
They studied 233 non-smoking pregnant women living in New York, measuring levels of a common pollutant in umbilical cord blood and then levels in the children's urine at ages three and five
Professor Perera said this is the first time a link has been established between prenatal PAH exposure and ADHD symptoms.
She told LiveScience: 'If replicated, then these findings could lead to new ways or stronger ways, better ways, to prevent ADHD.
'By nature, environmental exposures are preventable, this we consider one possible contributor to ADHD and one that's preventable, and the findings should be followed up so that necessary preventive strategies could be taken.'
She said pregnant women concerned about the effect of pollution levels on their unborn babies, can eat plenty of fresh produce which helps offset the effects of pollutants.

Could explain the behaviour of some of our "High Value" customers...
But wait, the answer is at hand! All we need to do is consume fresh produce! Lucky there is an abundance of that produced right here in the pearl river delta region! Or that expensive imported stuff, but we might need to have a pay rise to afford that, or at least acknowledge that our inflation rate is vastly different from the one calculated on a basket of goods from the wet market.

And as JTZ so eloquently pointed out can be picked up early in their writing, thats lacks capitalisation, and misspelt expletives.

Maybe its because pollution is more prevalent in big cities.
And maybe its a co-incidence that ultra-liberal, hover parenting psychobabble-infused mothers are more likely to live in big cities.
And maybe its a co-incidence that in big cities there are more psychologists telling them that its not their wishy-washy parenting that has resulted in uncontrollable brats. Its "the ADHD"... its the demons living inside their kids' heads, whispering in their ears, soaking up the ritalin.
And maybe its a co-incidence that big cities are more likely to carry left wing media that asserts that a smack on the hand for your kid, is tantamount to child abuse.

Its interesting that a number of the replies attack either the syndrome, or the actual scientific finding.
Doesn't anyone really want to know what it is this toxic filth that we and our children filter through our respiratory systems with every breath?
It is clearly not in the governments interest to accurately measure the filth, or get an independent body to measure it, and determine what is in it. The last clown that ran this town said "it only hurts our feelings." Clearly a numpty statement made by an individual who personally profited from the premature deaths of millions of people during the few years he steered the ship.
Reports suggest 1.2 million people a year prematurely die because of air pollution in China, (yes we are part of China). So roughly the population of Auckland EVERY YEAR and climbing. When do we start thinking this might be getting a bit out of hand?
Rather than arguing about the validity of ADHD as a pollution induced disease or possible variables that may or may not have swayed the results of the latest findings, why don't we voice our disgust at the filth that is pumped out of the chimneys and exhaust pipes of unscrupulous businesses, who blatantly profit from the poisoning of 1.2 million people a year?
What is in this airborne filth we are breathing every second of every day, and what is it doing to us and our families?
