It's been a bad week for picking on kids - especially overweight ones.

First came a repulsive fat-shaming video on 'Slate' called Dear Prudence: A girl with an endless appetite. In response to a letter from a "concerned" mother about the eating habits of her daughter's friend, agony aunt Prudie thought it would be helpful - funny even - to portray the little girl in question as a pig and her parents as tubs of lard.

Next came news out of the US of children being given homework assignments in which they were to circle the fat people in a picture. Another school weighs its students and has them taking letters home to parents with their BMI score.

The crowning glory of kiddy fat shaming, though, was Australia 'Biggest Loser's' paid advertorial on 'Mamamia', where Jo Abi advocates putting kids on diets, and where the show promises to focus on children more in this year's show. 

And let's not have any guff about 'The Biggest Loser' being "inspirational" or about health. It exists for one thing, and one thing only: to increase network ratings, often at the expense of the contestants' health.

The show has been slammed by health professionals and contestants alike, with the 'Sydney Morning Herald' reporting horror stories of trainers suggesting contestants stop drinking for up to 36 hours before being weighed, and celebrating dangerous and unrealistic weight-loss goals of up to 17 kilograms in one week.

Former contestant John Jeffery quit the show in 2008 because he feared someone would die. He wasn't being over-dramatic either. As it is, several contestants have been hospitalised for dehydration and Dr Jenny O'Dea, Associate Professor of Health and Nutrition Education at the University of Sydney, has warned against some of its practices, such as making morbidly obese people run 10 kilometres in the summer heat.


"Dehydration combined with heat exhaustion will kill you," Dr O'Dea said.

Add to this the psychological damage of being humiliated and bullied in front of an entire nation (why else do contestants have to strip off for weigh-ins, other than for us to be collectively appalled and amused by their bodies?) - and the very real possibility of contestants regaining the weight, and the associated shame. One contestant even blames 'The Biggest Loser' for triggering an eating disorder.

It's bad enough that we fat-shame adults for our entertainment, whilst pretending to be "concerned", but setting our fat-phobic sights on children is indefensible.

'The Biggest Loser's' fat-shaming-kiddies ratings bonanza is being promoted as a way to stop bullying. And hey, I understand that nobody wants their children to suffer. I also get that we live in a society where the parents of fat children are considered to be negligent.

But passing on our own food and body anxieties, and getting in first with the bullying by forcing children into diets and extreme exercise regimes isn't the solution.

Anyone who has ever tried to stick to a diet knows that the deprivation is soul-destroying and the self-restraint is all but impossible to maintain. When adults can't stick to calorie-restriction diets, how on earth do we expect children to?

Actress and comedian Arabella Weir explains in 'Does My Bum Look Big In This?' that denying children food is the fastest way to turn them into compulsive closet eaters with a terrible self-esteem.

"My parents believed they were helping me by pointing out to me that I ought not to waltz through life thinking it was ok to be me. They thought they were warning me of the pitfalls," writes Weir. "As I was, I wasn't good enough. I must learn denial in order to reach a better me, and one more pleasing to my parents. The only trouble was that that's quite a tall, if not unreachable, order for a child."

The idea of a child going hungry is barbaric. It's also totally unnecessary. If we weren't all so caught up on the aesthetics of our children's bodies rather than their health, we would never even consider it, let alone put it on prime-time TV.

Despite what the advertising industry and a whole stream of self-appointed TV "experts" tell us, skinny and healthy are not the same thing. We should not be aspiring to raise "skinny" children; surely our job is to raise "healthy" children.

If we encourage our kids to be active, to play outside and to eat healthy food because it's good for their growing bodies, bones and brains, and not because they need to hit some arbitrary figure on a weight chart, then we have done our job.

More than ever, we need to be teaching our children that the goal should be the process of living a health life and not the outcome of meeting a commercially-driven standard of beauty.

Once children internalise that their BMI is a measure of their goodness and self-worth, then we have set them up for a lifetime of failure and self-contempt. We have taught them that they should trust some arbitrary external measure rather than their bodies and their own judgment. And we have taught them that our love is conditional; that we will we be happier, prouder and more loving if they become something other than what they are.

What children need to hear from their parents, more than anything, is that we pick their team, and not team 'Biggest Loser'.

Playing action video games may improve reading in children with dyslexia, Italian researchers have found.

The small study, published online last week in Current Biology, involved two groups of 10 dyslexic children. One group played action video games for nine sessions of 80 minutes each, while the other followed the same routine with non-action games. The researchers bought the games in retail stores and have no financial interest in any video game company.

Age, I.Q., reading speed, error rates and phonological skills were similar in the two groups at the beginning of the study. The researchers measured the attention and reading skills of the children before and after the game sessions and then compared them.

Those trained on the action games scored significantly higher than those who played the nonaction games by various measures: combined speed and accuracy, recognizing pseudo-words made of random letters, and reaction time. The action game players also scored higher on tests that measured attention by inserting distractions as the children tried to accomplish various visual and auditory tasks.

“The correlation between attention improvement and reading improvement was very high,” said the co-first author of the study, Simone Gori, a postdoctoral fellow at the University of Padua. “The change in attentional abilities translates into better reading ability.”

Talk of a “sugar tax” in the US and New York's decision next month to ban sugary drinks in restaurants and theatres to young children has people  abuzz about whether it’s an American thing to financially punish people for drinking soda or not. I say go ahead and tax soda, and here are five good reasons why:

1. Soda is one more cause of the climate crisis. We have exported our carbon dioxide addiction all around the world. Just think of the costs in fuel to ship it—and the emissions produced. Maybe if we stop drinking so much of it, the appeal of American sodas will decline elsewhere. And at least in most other countries, the local soda is still made with real sugar!

2. Yeah, yeah, yeah…high-fructose corn syrup. HFCS is only cheaper than sugar because our government subsidizes the toxic, poisonous farming of corn in order to keep chemical companies (and maybe big tractor companies, too) in business. Plus, studies have shown that high-fructose corn syrup has mercury in it. So all those moms who think (incorrectly) that mercury in vaccines causes autism had better not be giving their kids soda!

3. Diet soda causes people to make poor decisions. According to a recent study, people who drink diet sodas think they are getting some energy, but their bodies still feel starved, so they kick into famine mode. Which basically means that the future doesn’t matter, all that matters is getting a next dose of fuel—hence, impulsive, short-term thinking. Amazing.

4. Soda isn’t really thirst quenching anyway. Did you ever really, really pay attention to how your mouth feels when you drink a soda? All that sugar kind of sucks out the liquids from your mouth and leaves a taste that is so icky you have to eat something to get rid of it. So not only are you getting empty calories from your drink, but you are urged to snack, too.


5. Fountain soda has fecal matter in it! It’s been a bad couple of weeks for soda in the news. Another study just this past week found that more than 40 percent of all fountain sodas have traces of fecal matter germs in them. It’s not in the ice, it’s in the soda itself. This was highly disappointing to me personally, since when I do have soda, I really like to have fountain soda with lots of ice in it to water it down and make it somewhat more thirst quenching. Now even that is off limits to me. I look at that cup of Coke with a lid and a straw and think, fecal matter? No thanks.

The only time I really bring soda into my house is when we are sick. There is nothing quite like a real coke or ginger ale to soothe an aching stomach. It’s medicine, really, and frankly, I think it should be treated as such. Think of all the plastic bottles, sugar, and toxic GMO corn we can keep out of the waste stream (and our bodies) if we stop drinking soda routinely.

Thirsty? Buy bottled water instead. YES, bottled water. It’s thirst quenching, has zero calories, and is damn good for you. Of course, you can fill your reusable water bottle with local tap water for free, instead of paying too much for water that’s been shipped and is probably municipal water anyway. And you should. But if you are at a gas station and need something to drink, pass over the soda and don’t feel guilty if a cold bottle of water hits the spot. (Just recycle that bottle.)

UK children are being seriously harmed by a "striptease culture in British schools and society" fuelled by the wide availability of internet pornography, a senior Labour figure warns today. 

Diane Abbott, a shadow health minister in Britain, will tonight warn that the "pornification" of culture is causing children to be "hypersexualised" at an early age.

At a meeting of the Fabian Women's Network, she will say parents are struggling to cope with the tide of sexual images available on social networking websites and the wider internet.

"For so long, it's been argued that overt, public displays of sexuality are an enlightened liberation," she will say.

"But I believe that for many, the pressure of conforming to hypersexualisation and its pitfalls is a prison. And the permanence of social media and technology can be a life sentence.

Ms Abbott will call for tougher internet controls to stop children getting access to pornographic images. She will say children should not be under pressure to engage in "sexting", where they send explicitly sexual images of themselves to others.


"I want to highlight what I believe is the rise of a secret garden, striptease culture in British schools and society, which has been put beyond the control of British families by fast-developing technology, and an increasingly pornified British culture," she will say.

"There's something wrong with a society as a whole when children say they have no one to turn to for advice because their parents - outwitted by technology, and struggling to juggle work and home life - don't really know what's going on.

"There's something wrong with a society when many young girls of all classes are pressurised into exposing themselves online, and are then humiliated.

"There's something wrong with a society that normalises children of every background 'sexting' from their bedrooms."

CHILDCARE centres are scrapping places for babies, as working parents wait up to two years for day care.

Three in every four long-daycare centres in Australia's capital cities do not have vacancies for babies, a new survey has revealed.

And two-thirds do not have places left for toddlers.

In Perth, parents are having to wait up to two years for a place forcing them to quit their jobs, rely on grandparents, or hire expensive nannies or unqualified babysitters.

The Greens' survey of 231 private and community daycare centres nationally in the past week shows that vacancies for babies have fallen 10 per cent since 2010.

In Perth, 19 per cent of centres have a waiting list six to 12 months long. And in 13 per cent of the 23 centres surveyed, parents are waiting up to two years for a place.

Perth parents are paying an average of $90 a day in childcare fees almost as much as in Melbourne ($96) and Sydney ($101).

The proportion of Perth centres with no vacancies for babies has jumped from half in 2010 to 61 per cent this year. And 58 per cent of Perth centres do not have vacancies for toddlers.

Australian Childcare Alliance president Gwynn Bridge said yesterday that parents were putting their unborn babies' names down on as many as 14 waiting lists at once.

Greens Senator Sarah Hanson-Young said there was obviously a looming crisis in the sector.

"The Government needs to be doing far more to improve both the quality and availability of child care while also helping mums and dads cover the costs," she said.

Here are some simple things you can do to help your child (and the rest of the family!) get ready to start Kindergarten:

• Read stories with your child about starting school.
• Go past the school and talk to your child about how they will soon be going there, the exciting things they will do and the friends they will make.
• Go along to the Kindergarten orientation at your school with your child. If your school does not have one, contact the school to arrange a time to visit.
• Spend time at school looking at all the activities going on.
• While you’re visiting, show your child around including where their bag goes and where the toilets are.
• Go shopping together to buy a special lunch box and drink bottle, and things they will need such as a school bag, uniform items and art smock. You will get a list of items from the school.
• Label all your child’s belongings with their name.
• Introduce yourself to other parents and become part of the school community.
• Organise play dates to help your child socialise with the other children in their class.
• Have a routine each morning as you and your child get ready to go to school.
• Iron clothes and prepare lunches and refrigerate the night before. This will make your morning routine easier.
• Make life easier for you and your child by buying clothing with large buttons or Velcro that will allow them to dress themselves. Being able to get themselves ready will also be a confidence boost for your child.
• Once school starts, ensure your child gets enough rest. You will probably find that your child is tired. This is normal as they adjust to their busy days at Kindergarten learning and playing.
• Get your child nutritious meals and snacks to keep them energised through the day.
• Talk with your child about their day when they get home. Your enthusiasm is important for them to see and feel, and will show them that school is important.
• Get to know your child’s teacher and don’t hesitate to talk to them about any issues you may have experienced, and give them feedback – both positive and negative.

Helping your child have a positive first experience of school is important because it can help shape the way they think about school in the future.

Once school starts, be actively involved yourself. Children love it when their mum or dad comes along to help with reading and other activities.

Your ongoing support will help them build strong foundations for success at school.

Before I ever became a mom, I was a teacher. While I don't claim to be a perfect teacher or a perfect mommy, I do believe that I relate to children quite well, thanks in part to my time spent "in the trenches." Those six precious years of forging relationships, offering guidance, and teaching science to 150 students each year taught me several things which have also served me well as a parent. Here are the eight most important.

1. Go Your Own Way
When you feel the need to discipline, be sure that this urge is coming from a bona fide need to do what's right and not from a knee jerk reaction to do things that were done to you as a child. This is how unhealthy cycles repeat themselves. Go your own way and always do What's in the best interest of your children.


2. For Every Negative, Find 10 Positives
We probably don't remember it, but it can be very hard to be young. Everything is new and must be learned from scratch. Sure, children will need to be corrected. But for the sake of your child's self-esteem and the harmony of your home, be sure to compliment them many more times on what they do right than correct them on what they've done wrong.

Examples: 

You brushed your hair very well today and it looks fabulous.

I love how you set the table without even being asked.

That's very sweet of you to draw me a picture today at school. I love it!

PARENTS and bubs given best possible start: Queensland parents and their newborns will have a better start to life, with the Newman Government launching new in-home support services for mothers and their babies.

Premier Campbell Newman said the ‘Mums and Bubs’ package of enhanced Maternal and Child Services would provide a helping hand when all parents and babies needed it most.

"Parenting is the hardest job in the world, but hopefully we can make the early stages a little easier by providing some practical extra support," Mr Newman said in a statement this week.

"This program will help develop healthy habits from the outset, laying good foundations in health, learning and development that could last a lifetime."

“It gives parents an outlet to gain information on issues like immunisation, breastfeeding and nutrition, providing a safe environment and the importance of reading to children.

Health Minister Lawrence Springborg said that the initiative, costing $28.9 million over four years, would ensure that all Queensland families get the best possible start to life by providing two home visits in the first month of a baby's life.

“Extra home visits provide better screening services for all Queensland families,” Mr Springborg said.

“These would be followed up with consultations at community centres at key developmental stages, namely, two, four, eight and 12 months of age.

"This is a significant improvement on the current schedule of visits, and now gives extra home visits to all Queensland parents.

"With more than 60,000 births in Queensland last year, this expanded service will make a big difference to families across Queensland."

“Becoming a parent can be an exciting time, but it can also be a time of uncertainty and anxiety for parents and families.

“Providing parents with support during this important time will help reduce health risk factors and increase protecting factors for a child’s future health.

“This service increases the capacity of all Queensland mothers and families, helping them to make decisions to improve the health and wellbeing of their children.”

Autism is the fastest-growing developmental disorder in the world, with the prevalence of diagnosis having increased by 600 per cent over the last 20 years, says Frank Viti, chief executive officer, Autism Speaks Canada 

In 1975, the prevalence number was 1 in 5,000; in 2001 it was 250; in 2012, the prevalence number has jumped to 1 in 88. As Bob Wright, co-founder of Autism Speaks, was quoted as saying, “We have an epidemic on our hands. The costs are staggering and will continue to rise as prevalence continues to increase.”

In the U.S., autism costs society $126 billion per year, which has more than tripled since 2006. With the new prevalence number of 1 in 88, this will jump to $137 billion.

Although there are some positive signs that show an increase in awareness of autism spectrum disorders as well as better detection and reporting of autism, these positive signs come with a need for programs and services to assist those affected by autism. There is also a greater need for access to treatment as the prevalence numbers increase. With this extra awareness, detection and reporting comes an increased need for funding.

Accessibility is also a problem. There are long wait times for diagnosis, and then it is a struggle to secure the appropriate educational services and therapies such as speech, behaviour and occupational therapies that are important to the development of someone on the spectrum. There is also a greater need to make ABA and IBI therapies more accessible. Canada’s Standing Senate Committee on Social Affairs, Science and Technology reported that in 2007, families were paying more than $60,000 a year on autism therapy.

We all must keep in mind that autism is not something you grow out of. There are thousands of adolescents and adults living with autism and there are not enough resources to help them find housing and employment so that they can lead meaningful and fulfilling lives with the same opportunities that their typically developing peers have. In 2007, the Standing Senate Committee reported that there were more than 144,000 Canadian adults on the spectrum and 48,000 Canadian children. As these young children with autism grow up, they will contribute to the increasing number of the already underfunded and under-resourced adult population on the spectrum. Much more attention needs to be paid to developing programs and services that will help those adults on the spectrum now and to prepare for those who will enter adulthood on the spectrum down the road.

Autism places a tremendous financial and emotional burden that families must confront on a daily basis as they battle this disorder. They need resources to help lessen the constraints that they face in accessing diagnosis, treatment, programs, services and therapies. Costs need to be reduced and access increased, and until there is more substantial evidence that this is happening, autism will be an epidemic in our society.

Jonathan Weiss, Canadian chair in autism research, York University professor:

What a lot of people are saying is there are many reasons why those rates are higher than they were before. One of the major things we are realizing . . . is the complexity around this and that it really is a spectrum of difficulties. Before, we were looking for one specific type of person or look. Now we are seeing things much more broadly. So I think that awareness, better ability to diagnose, better measurement and better ability to track exactly what’s happening might be a lot of the things that are related to the newer numbers relative to older numbers.

When it comes to the cause of this, I’m not the best person to answer that because I’m not looking at the genetics or the environmental influences on the genetics of a very complex disorder.

Awareness, more ability to diagnose and better-trained professionals across Canada and in the U.S. are recognizing many of the people who before weren’t being recognized.

Stephen Scherer, Director, University of Toronto McLaughlin Centre and The Centre for Applied Genomics, Hospital for Sick Children:

The Autism and Developmental Disabilities Monitoring Network of the U.S. Centers for Disease Control (CDC) has surveyed the prevalence of autism spectrum disorder (ASD) among 8-year-olds from up to 14 U.S. centres every two years since 2000. The most recent analysis pertains to the 2008 cohort, estimating overall prevalence as 1 in 88 children — almost double that of the original, 2000 cohort. So I suppose this substantial observed increase would indeed support the possibility of an autism epidemic, with the caveat that these data cannot distinguish the proportion of the increase attributable to changes in case ascertainment, as opposed to a true increase in ASD prevalence.

Our colleagues in Montreal, Drs. (Mayada) Elsabbagh and (Éric) Fombonne, undertook a comprehensive survey of epidemiological reports to catalogue the global prevalence of ASD and found that it is often under-recognized, particularly in the developing world. Variation in prevalence estimates is largely accounted for by variability in ascertainment and measurement, but environmental exposures may also play a role.

All of these data and my own observations lead me to believe that ASD prevalence is rising incrementally, but that so far there has not been an outbreak, nor is it pandemic. We now know from both the genetic and clinical sense that ASD is highly heterogeneous, so there are many targets or paths that can trigger or lead, respectively, to a diagnosis of ASD. Add to this mix the many new selective pressures being imposed on our brain’s development by the information-based society we now live in, and these phenomena too may account for some of the increase we see in ASD prevalence.

Temple Grandin, one of the world’s most accomplished and well-known high-functioning autistic adults. She is an animal sciences professor at Colorado State University, author and livestock industry consultant on animal behaviour:

Mild autism or Asperger’s has always been here. I’ve worked in a technical industry for 40 years and . . . they’re everywhere. They just used to call these people nerds before . . .

One of the things that helped them (succeed) is that in the 1950s, they taught social rules. Kids were taught table manners, how to shake hands, how to say please and thank you. That was just taught to all children in the ’50s. So they were better able to cope in society.

However, I think severe autism — where children remain non-verbal into adulthood — has increased. I don’t think the total increase would be just the previously undiagnosed Asperger’s. That would probably only be half of it.

Environmental contaminants could be one (explanation). Older parents could also be a factor. One of the problems that a male has is that when he gets older, his sperm has to be copied every two weeks. He makes a copy of a copy of a copy. So as he ages, you get copying mistakes. Women have all their eggs from birth. They are not copied constantly . . .

Kids (today) don’t get enough exercise, they don’t have enough omega 3 in their diets . . . In the ’50s we ate a lot more wild fish. Also, there is more mercury and solvents in the environment.

The other thing is there are a lot more psychiatric and other types of drugs taken during pregnancy. Epilepsy drugs, anti-depressant drugs, a lot of these drugs weren’t taken during the ’50s.

Mike Lake, whose now 17-year-old son, Jaden, has autism, is Conservative MP for Edmonton-Mill Woods-Beaumont:

I’ll leave that question for the scientists to answer. But when you are looking at those numbers I would certainly say that there is a combination. We are doing a better job of recognizing it. So there’s a better job of diagnosis. So that certainly plays into those numbers. But I do believe — and I think if you talk to most families that live with someone with autism — that we would recognize more of it in society as well. So I think you are seeing a combination of the two.

We need to continue with the momentum that we are building. Right now for example in Canada we have some of the best researchers in the world. Talking to Jonathan (Weiss), I have no reason to believe he won’t be another one of those researchers. There is some phenomenal research going on right now. You see Stephen Scherer in Toronto on the Autism Genome Project, really taking a leadership role worldwide with that. Someone like Lonnie Zwaigenbaum and Susan Brison. That list is long and it’s getting longer all the time . . .

Then there is the treatment side of things. And of course most of the treatment in this country falls to the provincial level, so a big part of the equation is getting out to the provincial elected officials and first of all educating them on what autism is because I still don’t think everybody understands exactly what it is and what the challenges are . . . (Then) they can make the right decisions in terms of funding for not only treatment for kids, which tends to be a big focus, but recognizing that autism is a lifespan issue. People with autism live just as long as you or I . . . so there are transitions into school, out of school into the work environment. And then housing challenges and what happens with these kids that become adults that become seniors when we’re gone as parents. That’s a question that all parents grapple with.

Dr. Evdokia Anagnostou, child neurologist, clinician scientist, Bloorview Research Institute; assistant professor, department of pediatrics, University of Toronto:

There is no doubt that the rate of diagnosing autism spectrum disorders (ASD) has been increasing . . .

The question remains whether the increase in the diagnosis is due to a true increase in the incidence of autism spectrum disorder (the true risk of developing ASD) or whether other methodological factors account for this increase.

Possible culprits include changes in the diagnostic criteria, making the diagnosis earlier and earlier so that younger kids are included in the numbers, diagnostic substitution (we diagnose more ASD now than global developmental delay or language disorders compared to one to two decades ago), and increased awareness of the diagnosis, so that teachers, parents and front-line clinicians are more likely to look for signs and symptoms of ASD. All of these would have been predicted to increase the number of children diagnosed, and have been shown to do such in various studies.

The question still remains, after all of this is accounted for, is is there a true increase in the incidence of the disorder?

We do not know the answer to that yet, but that does not mean that we should not be investigating this possibility. Specifically, although we know that ASDs have a strong genetic component, and we absolutely need to understand that more fully so that we can understand the biological paths that may be potentially targets for treatment, there are factors within and out of the human body that influence the degree of gene expression.

In other words, although children with autism carry genetic variations that either cause ASD or increase the risk of ASD, there may be interactions with the environment, whether this is the environment around conception (e.g., recent data related to paternal age), fetal environment or the environment outside of the body that may influence how these genes ultimately affect the function of brain and other biological networks.

As such, studies of the epidemiology of ASD, as well as our genome and gene-by-environment relationships, are still critical to fully answer this question.

Catherine Lord, director of the Center for Autism and the Developing Brain (a collaborative program between New York-Presbyterian Hospital, Weill Cornell Medical College and Columbia University, in partnership with the New York Center for Autism):

The number of children identified as having autism spectrum disorders has clearly been increasing for the last 30 years, with the steepest increases in the last 15 years. Some of this increase is accounted for by diagnostic substitution. That is, children who once received diagnoses of mild intellectual disability or receptive-expressive language disorder are now recognized as having autism spectrum disorder.

However, this shifting only accounts for a small proportion of the increase in numbers. Some of the increase is accounted for by increased awareness and access to services. We can see this in the U.S. Centers for Disease Control numbers, because parents who are not native English speakers, parents who have less education and families in regions with fewer services all have significantly fewer children with ASD in studies, something that seems very unlikely in reality.

We also know that from (the 1987) DSM III-R on, with broader references to difficulties in social reciprocity, as opposed to references to much more severe “lack of social awareness,” that the concept of autism has broadened. However, all of these factors do not necessarily add up to the very large numbers of children being identified now.

A recent study in the U.K., using similar standardized diagnostic methods to those in many other studies in Canada, the U.S. and Europe, found that 1 in 100 adults met diagnostic criteria for ASD, most of whom had never received an ASD diagnosis, though most of them were receiving some kind of psychiatric or social support, and many were not employed or living independently.

If 1 in 100 adults has ASD, then this would not suggest that the numbers of young children are not increasing as much as that, with careful searches, we are doing a better job of finding people with ASD — both children and adults (in that particular study, not necessarily in other circumstances).

Another research finding that suggests caution is that there is very large variation in how many children are identified with ASD in the U.S. in the CDC studies, and even in the baby sibling research projects, where methods are similar and researchers are all well-trained. My bias, as a clinician who works with families with family members with autism, is that most of the variation is accounted for by underestimates — that is, in some areas of the U.S. we are still missing many children, particularly children who are not in the famous “1 per cent” of affluence, with ASD or misdiagnosing them as having other disorders. However, I know that I am biased.

With adults and with the baby sibling studies, it is harder to know what is going on. Our clinic does see some self-referred adults hoping to get diagnoses of ASD that they can use to account for life problems such as marital problems or job losses or problems with the law, when ASD is not appropriate. In contrast, we also regularly see adults whom we do diagnose with ASD who have never received an autism diagnosis before but have clearly struggled with the difficulties associated with autism since early childhood, and just never had a good assessment. For children, my experience is that far fewer families seek diagnoses of ASD when they are not appropriate.

Putting this information together, I do not believe that we can rule out the possibility that the numbers of children with autism are increasing beyond diagnostic substitution and increased awareness, but we need to be very careful how we study these changes.

As a former Edmontonian and proud wife and mother of Canadians, I can proudly say that the Canadian health and social systems are much more uniformly accessible within provinces than these services in the U.S. and offer an opportunity to figure out what the true nature of these changes in numbers mean.

I avoid the use of the word “epidemic” because it has connotations of contagion and fear, which I do not think are helpful for families. But I think we need to understand what is happening.

Is There an Autism Epidemic?
by Dr. Steven Novella

There is no question that the rates of autism diagnosis have been increasing in the US and the Western world. The latest Centers for Disease Control (CDC) estimates indicate that 1 in 88 children have been diagnosed as being on the autism spectrum (1/54 boys and 1/252 girls). This is up from just two years ago when the estimate was 1/100 children, and much higher that the 1990s when estimates were around 1/250.  

It certainly looks like we are in the middle of an autism epidemic, but experts are not so sure, and for good reason.  

As a general rule in any scientific discipline when a measured quantity is changing over time you have to consider the possibility that the method of measurement is changing, rather than the thing being measured itself. In medicine this often relates to the method of diagnosis. To be precise we often say the rate of diagnosis is increasing (or decreasing), rather than the rate of the disease - unless all diagnostic artifacts have been reasonably ruled out.  

Autism is particularly susceptible to diagnostic artifacts. Various factors have been identified that could, and probably are, affecting the rate at which the autism diagnosis is made.  

The first is an expansion in the diagnosis itself. In fact autism is part of what is now called autism spectrum disorder, because we recognize that it exists along a fairly broad spectrum. If you cast a wider net, you're going to catch more fish - that doesn't mean there are more fish.  

Related to this issue is the fact that autism is a clinical diagnosis - it's based on recognizing a set of signs and symptoms. At present there are no biological markers that can be used to reliably diagnose autism. There is therefore no laboratory confirmation or objective result that can be used to compare prevalence over time. Clinical judgment is required, and that judgment can drift over time.  

Awareness and familiarity with autism can therefore also lead to more diagnoses. Teachers may be more likely to consider the diagnosis and raise the issue with parents, and doctors may be more likely to make the diagnosis.  

Yet another related issue is so-called diagnostic substitution. There are several related diagnoses the may be more likely to be diagnosed as autism today. Two or three decades ago, however, the same children might have been diagnosed with a non-specific developmental disorder, or a language disorder.  

Surveillance is another issue - the effort being made by school systems and others to identify children who have special needs because they fit on the autism spectrum.

The scientific evidence strongly supports a major role for all these various factors in explaining the increase in autism diagnosis. Studies have shown that there is diagnostic substitution (as autism diagnosis goes up, other related diagnoses go down), there is increased surveillance, and there is wider recognition of autism. The chance of having a child diagnosed with autism strongly corresponds to living near other families with a child on the spectrum, and being in the same school system. Therefore social contact with others with the diagnosis increases the chance of being diagnosed.  

Several studies have shown that when the same methods are used to compare different cohorts of children born at different times, the autism prevalence is the same. Further, the prevalence of autism in different age groups (when the same surveillance and diagnostic methods are used) appears to be the same. If the true incidence of autism were increasing then younger age groups would have a higher prevalence.  

It is possible, therefore, from these various factors that the apparent rise in autism is entirely an artifact of diagnosis and surveillance. It is difficult to prove this, however, and so there is always a certain amount of uncertainty. It is also possible that there is a real increase in the incidence of autism over time, but there is no data that establishes that there is a real increase beyond the factors described above.  

Of course there are some groups that are invested in the notion that autism is truly increasing and represents an epidemic. Most notable is the anti-vaccine movement, who over the last decade have been blaming the increase in autism on vaccines. Initially they blamed autism on the MMR vaccine, but the scientific data did not support that claim, and the credibility of the originator of this fear, Andrew Wakefield, has since crashed and burned.  

After the MMR hypothesis failed they next turned to mercury in the form of thimerosal in some vaccines. They confused correlation with causation by arguing that autism rates were increasing as the vaccine schedule also increased. By the end of 2002, however, thimerosal was removed from the routine vaccine schedule in the US, and therefore the amount of exposure to thimerosal plummeted. Advocates of the thimerosal hypothesis (such as David Kirby) predicted that autism rates would also plummet.  

They were correct in that, if thimerosal were a significant contributor to autism then the rates should drop considerably once thimerosal was largely removed from childhood vaccines (it was still present in some flu vaccines). Since 2002, however, autism diagnosis rates have continued to increase at the same rate. We are now 10 years later, and there is simply no justification for clinging to the thimerosal hypothesis any further (of course this hasn't stopped antivaccinationists).  

Ironically the antivaxers are now using the continued increase in autism diagnosis to argue that vaccines cause autism, even though that increase contradicts their prior predictions.  

The data clearly shows that much, if not all, of the increase in autism is due to expanded diagnosis and surveillance. It is still possible that there is a real increase, but more research would be needed to establish that.  

However, regardless of cause, we now know that autism is very common. It therefore deserves a proper level of attention and resources, both for research and services for those on the spectrum.
