the parts of our 1 which may influence body shape, including the classic "apple" or "pear" shape in women, have been revealed.

人体dna的某些部分可能会影响到体型,例如女士经典的“苹果型”“圆润型”体型。日前这些部分已被发现。

the genes help determine body shape

a uk study in nature genetics found the locations of 13 genes which may play a role, with a stronger effect in women.

where body fat lies may affect 4(糖尿病) and heart disease risk, so the results could shed light on those diseases.

a british heart foundation spokesman said the findings could lead to new dietary advice or medicines.

it is known that men and women who carry more fat around their waists compared with their bottoms and 5(大腿) are more 6 to diabetes and heart disease - but the reason why fat accumulates in different places is far less clear.

the scientists, led by researchers at 7 university and the medical research council, looked at the 3 code of more than 77,000 people, looking for genetic regions which could be linked to differences in body fat distribution.

although the 13 locations highlighted probably only account for a tiny fraction of the variation in the ratio between waist and 8, they are more likely to point towards the 9(潜在的,根本的) body 10 which control fat storage.

genes known to be involved in controlling 11(胆固醇) , insulin(胰岛素) , and insulin resistance - linked to the development of diabetes - fall within the 13 regions.

'stepping stone'

the fact that the effect of genes in these locations may be stronger for women than for men also 12(激起兴趣) the researchers.

dr cecilia lindgren, of the wellcome trust centre for human genetics at oxford, said: "by finding genes that have an important role in influencing whether we are apple-shaped or pear-shaped, and the ways in which that differs between men and women, we hope to home in on the crucial underlying biological processes.

"understanding biology through finding genes is just a first step in a long journey towards treatment, but it is a vital one."

a second, even bigger study looked for genetic variations connected to differences in "body mass index", the standard measure of weight vs height used as a guide to whether a person is a healthy weight.

they found 18 new genetic 13 involved in people with higher bmi - in fact, people who inherited(继承) many of them weighed as much as 9kg (1st 5lbs) more than those who had only inherited a few.

dr ruth loos, who led this study, said that the two studies combined may eventually lead to better ways to prevent 14 and even the development of new drugs.

professor jeremy pearson, associate medical director at the british heart foundation, said: "we've known for some time that while fat anywhere in your body is not good for you, fat around the tummy(肚子,胃) increases your risk of heart disease and other illnesses more than fat around the 15.

"we've also known that the pattern for where our body stores fat is partly controlled by our genes, but only one of the genes responsible had been discovered.

"it's likely that several of these new genes will control the behaviour of fat cells. this will need to be confirmed with further research, but these findings are a good stepping stone towards how we might be able to offer new dietary advice or medicines to control the pattern of fat distribution in future."
