Twenty years ago, an expert panel at the National Institutes of Health lowered the BMI cutoff for being overweight from 27 to 25. But a recent report suggests that for one segment of the population — postmenopausal women – that might not be low enough. Also, to define obesity in this population the cutoff of 30 might be too high.
Will "Adiposity-Based Chronic Disease" change personal behavior, the way the term "obesity" could not? Two scientific associations that made the switch hope it will.
When trying to identify why many young children gain weight at an early age, schools often are criticized. But a new, large study indicates that schools are being unfairly implicated in this regard, and that significant weight gain is taking place at home -- specifically, during summers away from school.
Prostate cancer can be indolent, not posing a risk to life — or aggressive, leading to an increased risk of death. A new analysis from the large EPIC study suggests that increases in BMI and waist circumference are associated with an increased risk of the aggressive form, and thus to an increased mortality risk.
According to a new Danish study, obesity isn't as bad for health as it used to be. More exactly, the BMI associated with the lowest mortality risk seems to be higher than it was 40 years ago. But given some of the problems associated with using BMI to estimate obesity, we're not so sure that these results apply to everyone.
It's well accepted that being obese, or even overweight, isn't good for you. But some data suggests that these states might actually be healthy — a situation known as the obesity paradox. A new study suggests that this apparent contradiction is tied to the metric used to decide who's fat and who isn't — the BMI.
Insurance companies may be able to charge higher premiums for employees with higher body mass indices, should the EEOC adopt this proposal as a rule. Meanwhile, a new study found that nearly half of Americans who are deemed either overweight, or obese based merely on their BMI, are actually healthy.
Although we know that obesity is associated with an increased risk of numerous ills, it hasn't been clear that it's also linked to an increased risk of death. A new study suggests that the way the BMI data has been examined may account for that dissonance, and that body weight history may also weigh in on mortality risk.
Today, 25 states weigh public school students to monitor obesity rates. In 10 of these states, parents are then notified. Today s New York Times addresses these BMI report cards and their effect (or lack thereof).
Fast food often gets a bad reputation, but the solution to the obesity epidemic does not involve limiting fast food restaurants. According to new
Obesity (defined as a BMI of 30 or more), especially extreme obesity, is known to decrease the likelihood that a woman can become pregnant. In addition, when obese women do become pregnant, they are more likely to develop gestational diabetes, and have an increased risk of large babies, early delivery, and stillbirths, and their infants are at increased risk of congenital malformations.
A higher BMI may lead to an increased risk for diabetes complications, a new study finds. Using data from the Medicare Current Beneficiary Survey (MCBS), researchers examined relations between excess weight and time to first diagnosis of type 2 diabetes and its
