| Are
You Overweight?
Scientific studies clearly
indicate that obesity is linked to increased sickness and death rates. Hypertension,
elevated levels of cholesterol, heart disease, stroke, certain cancers, gall bladder
disease, back pain, arthritis, abnormal pulmonary function, and sleep apnea are
physical problems intensified by obesity. The health risks of being overweight
may be prevented by achieving and maintaining an ideal body weight.
Obesity
is determined using body-mass index (BMI), a method of comparing height to weight.
A BMI of 25 to 29.9 is considered overweight, and a reading over 30 is considered
obese. A BMI of 19 to 24.9 is considered normal weight. Using that standard, obesity
researchers have estimated that more than half of adult Americans are either overweight
or obese. Body
mass index (BMI) has been the medical standard for obesity measurement since the
early 1980s. Government researchers developed it to take height into account in
weight measurement. For example, let's say someone weighs 150 pounds. Is he or
she obese? That's impossible to say without knowing the person's height. The answers
would be different for someone who is 5' 0" tall, 5' 5", and 6'.

BMIs are in the range of 20 to 26.
The "overweight" range is
26 to 27.3 for women, 26 to 27.8 for men, though some authorities peg the upper
limit of overweight at a BMI of 30.
Most authorities say that "obesity"
begins at BMIs above 27.3 for women and 27.87 for men. All authorities agree that
anyone with a BMI over 30 is obese.
According to these conventions, the
woman who is 5' 0" and weighs 155 has a BMI of 30.14, is considered obese.
Someone who is 5' 4" and weighs 155 has a BMI of 26.6, is considered
to be overweight, but not obese.
Someone who is 6" and weighs 155
is in the healthy BMI range. |
