Big hips impair women’s memory, a study finds研究發現,臀部大影響女性記憶

A woman’s body shape may influence how good her memory is, according to US researchers. Although carrying excess weight anywhere appears to impair older women’s brains, carrying it on the hips may make matters worse, they say.
The Northwestern Medicine team found "apple-shaped" women fared better than "pears" on cognitive tests. But depositing fat around the waist increases the risk of cancer, diabetes and heart disease, experts warn.
The researchers believe belly fat makes more of the female hormone oestrogen that naturally dips after the menopause. Oestrogen is thought to help protect the brain from cognitive decline.
The study involved 8,745 post-menopausal women aged 65 to 79. These women were asked to complete a 100-point memory test that doctors use to judge brain function. They were also weighed and measured, then scored on an obesity scale known as Body Mass Index or BMI. Over two-thirds of the women were overweight or obese.
The researchers found that for every one point increase in a woman’s BMI, her memory score dropped by one point. And pear-shaped women - those with smaller waists but bigger hips - scored particularly poorly.
