How much of pregnancy health advice is plain old prejudice and fear?

Questions as to whether pregnant women should drink alcohol or coffee go beyond the restrictions of an over-cautious medical establishment. It’s to do with how we value people. In her book <em>Expecting Better</em>, Emily Oster has raised some issues that

In 2007, when I was midway through my first full-term pregnancy, government advice on alcohol consumption during pregnancy changed. Moderate drinking – one to two units a week – was reduced to no drinking at all. Crucially, there was no new clinical evidence to support this change. It was simply in order to be “on the safe side”.

I felt furious, so furious I wrote to the Department of Health. I’d given up alcohol anyhow – again, to be “on the safe side” – but that, it seemed to me, was a personal preference. Having someone else tell me to be over-cautious was another thing entirely. It wasn’t booze that was being withdrawn, it was a basic level of respect for the decision-making capabilities of anyone who was pregnant.

In Expecting Better, Emily Oster describes how in her experience, “being pregnant was a lot like being a child again. There was always someone telling you what to do”. You are patronised and ordered to restrict your realm of experience significantly, yet the reasons why can seem – and often are – terribly flimsy.

Exploring this in more detail (at first merely in order to gain “permission” to drink a cup of coffee) Oster found that the evidence used to back up many pregnancy recommendations is weak or based on poor research. She discovered that the decision-making processes she, as an economist, taught her students – collect data, but also weigh up personal costs and benefits – did not seem to apply. Oster’s book is the result of her own research, her key aim being to present data that will allow others to make their own cost and benefit calculations. “This book,” she writes, “is very specifically not about making recommendations; it’s about acknowledging that if you have the right information you can make the right decision for yourself.”

Expecting Better is a pregnancy guide, not a political tract, and as such it deserves much praise. It’s a book I would recommend to anyone expecting their first child. Nonetheless, I’d add the proviso that while you don’t have to be middle-class to read it, it helps. It’s always easier to challenge received wisdom when you’ve got a little unearned authority behind you to start with, as I discovered when the Department of Health responded to my letter (was the use of my Dr title the reason why the new rules drinking rules weren’t “aimed at women like you”?). Facts matter, sure, but so do social judgments and stereotypes. A lack of information is just one of many things which hold us back from making the choices that are best for us.

I don’t wish to criticise a book for all the things it doesn’t say, particularly if it never set out to say them in the first place. However, right now I’d like to see a different book on pregnancy, risk and choice, one that looks beyond merely presenting the facts and towards the social and cultural conditions that still militate against autonomous decision-making. Class is one factor, but I suspect sexism and ingrained anti-choice sentiment also play their part. It’s all very well for Oster to explain that “the value of having numbers – data – is that they aren’t subject to someone else’s interpretation. They are just the numbers. You can decide what they mean for you”. But in the real world, sadly, that’s just not true.

Clearly there’s no law (as yet) against a pregnant woman wanting the odd cappuccino. But what about the widespread belief that such a woman’s wants are irrelevant when set against anything that could, in one’s wildest imagination, harm the foetus? Such a woman will be told that coffee avoidance isn’t a personal matter but a moral absolute. So what if she’s read Oster’s book and knows for sure that one measly cup is absolutely fine? She also knows that “absolutely fine” doesn’t count for much when you’re reduced to a walking womb whose feelings and desires take second place. This is an issue that goes beyond the restrictions of an over-cautious medical establishment. It’s to do with how we value people. In the US we’re increasingly seeing those who are pregnant imprisoned for taking risks that everyone else is allowed to take with impunity. At this point what may have started out as merely flawed advice becomes a serious human rights issue.

It would be interesting to see how recommendations made to those who are pregnant compare with those made to people facing other medical conditions. Yes, we all get patronised and pressured into accepting treatments which benefit us more on paper than in real life, but are there subtle differences in priorities and value judgements when the wellbeing of the innocent unborn is at stake? Perhaps there’s a hierarchy in place. For instance, are there also links between the way in which the pregnant have to suck it up for the hypothetical good of others and ways in which some sufferers of mental illness endure treatments which destroy their quality of life but make others – yet more supposed “innocents” – feel “safer”? How much of a factor is plain old prejudice and fear? Who gets to own his or her own body?

I think these are questions worth answering, if not by Oster, then by someone willing to take her pure data and re-examine it alongside the powerful distortions wrought by social pressure and moral censure. In the meantime, however, I’d thank Oster for how far she’s brought this debate already. Even if the initial motivation for her research was her own dread of a caffeine withdrawal headache, she’s written something that should be of practical value to all those who are pregnant – providing the rest of society allows it to be.

The deafening killer - why noise will be the next great pollution scandal

A growing body of evidence shows that noise can have serious health impacts too. 

Our cities are being poisoned by a toxin that surrounds us day and night. It eats away at our brains, hurts our hearts, clutches at our sleep, and gnaws at the quality of our daily lives.

Hardly a silent killer, it gets short shrift compared to the well-publicised terrors of air pollution and sugars food. It is the dull, thumping, stultifying drum-beat of perpetual noise.

The score that accompanies city life is brutal and constant. It disrupts the everyday: The coffee break ruined by the screech of a line of double decker buses braking at the lights. The lawyer’s conference call broken by drilling as she makes her way to the office. The writer’s struggle to find a quiet corner to pen his latest article.

For city-dwellers, it’s all-consuming and impossible to avoid. Construction, traffic, the whirring of machinery, the neighbour’s stereo. Even at home, the beeps and buzzes made by washing machines, fridges, and phones all serve to distract and unsettle.

But the never-ending noisiness of city life is far more than a problem of aesthetics. A growing body of evidence shows that noise can have serious health impacts too. Recent studies have linked noise pollution to hearing loss, sleep deprivation, hypertension, heart disease, brain development, and even increased risk of dementia.

One research team compared families living on different stories of the same building in Manhattan to isolate the impact of noise on health and education. They found children in lower, noisier floors were worse at reading than their higher-up peers, an effect that was most pronounced for children who had lived in the building for longest.

Those studies have been replicated for the impact of aircraft noise with similar results. Not only does noise cause higher blood pressure and worsens quality of sleep, it also stymies pupils trying to concentrate in class.

As with many forms of pollution, the poorest are typically the hardest hit. The worst-off in any city often live by busy roads in poorly-insulated houses or flats, cheek by jowl with packed-in neighbours.

The US Department of Transport recently mapped road and aircraft noise across the United States. Predictably, the loudest areas overlapped with some of the country’s most deprived. Those included the south side of Atlanta and the lowest-income areas of LA and Seattle.

Yet as noise pollution grows in line with road and air traffic and rising urban density, public policy has turned a blind eye.

Council noise response services, formally a 24-hour defence against neighbourly disputes, have fallen victim to local government cuts. Decisions on airport expansion and road development pay scant regard to their audible impact. Political platforms remain silent on the loudest poison.

This is odd at a time when we have never had more tools at our disposal to deal with the issue. Electric Vehicles are practically noise-less, yet noise rarely features in the arguments for their adoption. Just replacing today’s bus fleet would transform city centres; doing the same for taxis and trucks would amount to a revolution.

Vehicles are just the start. Millions were spent on a programme of “Warm Homes”; what about “Quiet Homes”? How did we value the noise impact in the decision to build a third runway at Heathrow, and how do we compensate people now that it’s going ahead?

Construction is a major driver of decibels. Should builders compensate “noise victims” for over-drilling? Or could regulation push equipment manufacturers to find new ways to dampen the sound of their kit?

Of course, none of this addresses the noise pollution we impose on ourselves. The bars and clubs we choose to visit or the music we stick in our ears. Whether pumping dance tracks in spin classes or indie rock in trendy coffee shops, people’s desire to compensate for bad noise out there by playing louder noise in here is hard to control for.

The Clean Air Act of 1956 heralded a new era of city life, one where smog and grime gave way to clear skies and clearer lungs. That fight still goes on today.

But some day, we will turn our attention to our clogged-up airwaves. The decibels will fall. #Twitter will give way to twitter. And every now and again, as we step from our homes into city life, we may just hear the sweetest sound of all. Silence.
