Study: Body shape affects memory in older women
STORY HIGHLIGHTS
It's better to be an apple than a pear, study says
Extra weight affects memory in everyone, but where fat is located is important
Study includes more than 8,000 women ages 65 to 79
(CNN) -- A woman's body shape may play a role in how good her memory is, according to a new study.
The more an older woman weighs, the worse her memory, according to research released this week from Northwestern Medicine at Northwestern University in Evanston, Illinois.
The effect is more pronounced in women who carry excess weight around their hips, known as pear shapes, than women who carry it around their waists, called apple shapes.
The reason pear-shaped women experienced more memory and brain function deterioration than apple-shaped women is likely related to the type of fat deposited around the hips versus the waist.
Scientists know that different kinds of fat release different cytokines -- the hormones that can cause inflammation and affect cognition.
"We need to find out if one kind of fat is more detrimental than the other, and how it affects brain function," said Dr. Diana Kerwin, the lead author of the study and an assistant professor of medicine and a physician at Northwestern Medicine. "The fat may contribute to the formation of plaques associated with Alzheimer's disease or a restricted blood flow to the brain."
The study published in Wednesday's Journal of the American Geriatric Society said, on average, there is a one-point drop in the memory score for every one-point increase in body-mass index -- a ratio of a person's height and weight. The study included 8,745 cognitively normal, post-menopausal women ages 65 to 79.
"Obesity is bad, but its effects are worse depending on where the fat is located," Kerwin said.
"The study tells us if we have a woman in our office, and we know from her waist-to-hip ratio that she's carrying excess fat on her hips, we might be more aggressive with weight loss," Kerwin said. "We can't change where your fat is located, but having less of it is better."

Interesting. Yet, I heard it's better to be pear shaped rather than apple shaped in regards to heart disease. So, I guess we have to choose whether we'd rather have a heart attack or lose our memories, lol. Maybe if I lose my memory enough I won't care how I'm shapred! ROFL
Not to worry, by the time I get that old it will be all about the ears or some other off the wall theory. I remember when chocolate and coffee were bad, now there good. I heard the other day that smokers were nagged to death. I think there is some truth in that one actually!
lol...I was wondering where this will lead.
Hmmm. Scary to think women with more hip fat may be singled out by the 'food police' or harrassed by management over their body shape. Glad I'm retired.
