New research suggests that postmenopausal women who are "apple"-shaped rather than "pear"-shaped are at greater risk of heart and blood vessel problems, even if they have a body mass index (BMI, a ratio of height to weight
) in the normal range.
The study analyzed 2012 data from the National Institute on Aging's Health and Retirement study, and found that dog walking is associated with lower body mass index (BMI, a relation of height to weight
), fewer doctor visits, more frequent exercise, and an increase in social benefits for seniors.
A review of 51 studies finds that people with a body mass index (BMI, a relation of height to weight
) in the underweight range have a 1.8 times higher risk of dying from any cause than adults with a normal BMI.
A high body mass index (BMI, a ratio of height to weight
used to calculate levels of body fat) may be associated with poorer mental skills in older adults.
"The height to weight
ratio is also changing, which was the key indicator for successful teams.
The risk of new heart failure rises by about 11 percent for every one-point increase in body-mass index (BMI, a measure of body fat based on the relation of height to weight
) according to a 20-year analysis from the Physicians' Health Study published in the January issue of Circulation.
It is hoped the method used will provide more accurate indications of obesity than comparing height to weight
The average ratio of height to weight
is remarkably consistent in living human groups, and Neanderthals also fell within the upper limits of the modern human range, according to Aiello.
Body mass index (BMI), a measure of height to weight
, is used to calculate obesity, with a BMI of 25 or more considered overweight and 30 or more considered obese.
Researchers defined a low-risk lifestyle as including above-average physical activity, a healthful diet, light or moderate alcohol consumption, not smoking, a BMI (body mass index, a relation of height to weight
) of less than 25, and a waist circumference of 34.6 inches or less for women or 36 inches or less for men.
