IPHREHAB : OBESITY

IPHREHAB 

OBESITY

•It is often viewed as equivalent to increased body weight,
              This is somewhat arbitrary

•Obesity is a state of excess adipose tissue mass.

•Obesity is therefore more effectively defined by assessing its linkage to morbidity or mortality.

MEASURMENT

Body mass index (BMI), most widely used method to gauge Obesity

It is equal to weight / height2 (in kg/m2)

BMIs range from 19 to 26 kg/m2;

At a similar BMI, women have more body fat than men.

BMI of 30 is most commonly used as a threshold for obesity in both men and women. 

MEASURMENT

•Term overweight  is used to describe individuals with BMIs between 25 & 30.

•A BMI between 25 and 30 should be viewed as medically significant and worthy of therapeutic intervention .

•BMIs above 30 indicate Gross Obesity .

•He or she is definitely Overweight.

•Anthropometry (skin-fold thicknes)

•

•Densitometry (underwater weighing)
 

•CT or MRI, and electrical impedance

DISTRIBUTION

The distribution of adipose tissue has substantial implications for morbidity.

Intra-abdominal and abdominal subcutaneous fat have more significance. Pear Shaped Apple Shaped

Waist-to-hip ratio, with a ratio >0.9 in women and >1.0 in men being abnormal.

PREVALENCE

American adult population with obesity (BMI > 30) has increased from 14.5% to 22.5% 

50% of U.S. adults 20 years of age were overweight 

Obesity is more common among women and in the poor; 

The prevalence in children is  rising at a worrisome rate.
