Slim waists: a health signal?

I just came home from office. It was a long day filled with discussions about anti-marketing approaches, against the current concepts, political correctness, the creation of tabus and the transgression of limits, many loose ends at the end of the day, but a few conclusions too by some means or other.
The guys ended the day by arguing about girls, their way to dress defensive or offensive concluding that the girls around them are definitely not dressing aggressively enough – I myself want to add at this point here – to stimulates their senses, a-pros-pos »tabu«…I break it, do you agree?…

And I quote a study for reinstating political correctness again (especially for you Lothar) published on news@nature.com that a slim waist has prooved to be one of the core parameters attracting males*.

»An hourglass waistline has impressed men for centuries« is the headline of Michael Hopkin article.

Being thin round the middle is one sign of health. Researchers claim that, for enduring popularity down the ages, nothing beats a narrow waistline.

A team in the United States surveyed accounts of female beauty in British literature from the sixteenth, seventeenth and eighteenth centuries, and found that the only feature that consistently got authors’ pulses racing was a slender midriff.

"The waist does not sound an intuitively sexy body part," admits Devendra Singh of the University of Texas, Austin, who led the study. But nevertheless, it was the one thing on which the hundreds of writers surveyed seemed to be unanimous. They didn’t even agree on whether large breasts, that modern staple of sexual attractiveness, are nice or not.«

I am always a little bit reluctant towards post-hoc interpretations of this kind, and moreover, what is the point of the whole thing? A slim waist is a health signal and therefore it became sexy? or how? For the sake of the survival of the human race?

A preference for a slim waist is also found in first-century Indian
writings and fourth-century Chinese works, Singh’s team previously
found.

The popularity of a slender middle might be due to what it reveals
about a woman’s health and fertility, Singh says. Healthiness is
associated with low levels of abdominal fat, and high levels of female
sex hormones such as oestrogen pinch the waistline and give the body an
hourglass shape.

British writings

Singh and his colleagues scanned a database containing some 345,000
works of British and American literature, selecting only older British
writings, and cross-referenced terms such as ‘waist’, ‘breast’, ‘hips’
and ‘buttocks’ with words such as ‘plump’ and ‘slim’. They report their
results in Proceedings of the Royal Society B1.

The evidence for preference of a narrow waist from around the world
and throughout the centuries suggests that it comes from something more
inherent than fashion or the influences of global mass media.

"Nowadays there’s no culture without Western influences, so it’s
easy to say ‘oh yeah they’re copycatting the West’," Singh says. "But
this shows that it cannot be explained as a whim of Western culture."

It might not be quite unanimous, however. In a 1998 survey in which
men from the indigenous Matsigenka people of Peru were asked to choose
their favoured female silhouette, most preferred a plumper lady and
some commented that slim-waisted women looked like they had been
suffering from fever and diarrhoea (see ‘World-wide waistlines’).

Health signal

A mini midriff may give men valuable information about a woman’s
potential to have healthy babies, and that could be why they
subconsciously find it attractive, Singh says. A similar theory has
also been used to explain why we subconsciously register highly
symmetrical features — an indicator of good genes — as more beautiful.

References to beautifully slim waistlines go all the way back to
ancient Egypt, Singh and his colleagues point out. The epithet of Queen
Nefertari, favourite wife of pharaoh Ramses II, who reigned almost
4,000 years ago, explicitly mentions her narrow waist.

The preoccupation has endured throughout the centuries, all the way
from the Venus de Milo to Playboy, Singh says. He dismisses as
"whimsical" the blubbery beauties made fashionable by the nudes of
seventeenth-century artists such as Rubens.

The discovery also suggests why Victorian women favoured corsets
over dieting, and potentially brings depressing news for today’s women
who might be unhappy with their bodies, Singh says. "Many women are
losing weight but will it give them the right body shape?"
