A cute little naked baby is grinning at the camera. "Is this the happiest she'll ever be about her appearance?" asks the slogan on the billboard. The ad was for a campaign last year to save future generations of women and girls from hating their bodies. For the explosion in cosmetic surgery - and explosion of breast implants inside women's bodies - is just a symptom of a corrosive unhappiness that begins only a few years after birth.
Three British psychologists have studied the effect of Barbie dolls on five- to eight-year-old girls. Barbie is ubiquitous - 99 per cent of American girls own at least one of her. Yet if Barbie were a real woman, her waist would be 39 per cent smaller than the average anorexic patient, and she would be far too thin to menstruate. Despite this skeletal state, she miraculously has big breasts. It is a body shape so unattainable that the chances of a woman naturally having her proportions are less than one in 100,000. And guess what? The girls in the study who played with Barbie became more dissatisfied with their own bodies and were more likely to say they wanted to be thinner than the girls who were given a normal-shaped doll to play with.
Is it surprising, then, that the average age at which girls start dieting is now eight? Or that the Barbie effect does not wear off? According to an American study, adult women who look at thin models in advertisements take just one to three minutes to feel worse about their bodies than they did at the start. A control group who were shown only the products without the models experienced no change in mood.
Women feel depressed because the ideal shape to which they are constantly exposed is almost as remote from reality as Barbie's. For a start, even the models - who are chosen for their preternatural proportions and beauty - don't look in real life as they appear in the ads. Their skin has been made flawless by airbrushing, their legs lengthened, waists narrowed and curves enhanced by digital manipulation.
Then, of course, there is the surgical work. Models have got thinner and thinner over the past few decades and, as all women know, if you lose weight your breasts get smaller too. It's almost impossible to be stick-thin and have big boobs - unless you go under the knife.
