- 4. 4 Definition of BMI BMI, formerly called the Quetelet index, is a measure for indicating nutritional status in adults. It is defined as a person's weight in kilograms divided by the square of the person's height in meter (kg/m2).
- 5. 5 Calculation of BMI Howto Calculate BMI 1. Multiply body weight in pounds by 703 2. Divide that number by height in inches 3. Divide that number by height once more EXAMPLE: For example, calculating the BMI for a 5'7" individual weighing 150 lb: 1. 150 lb 703 = 105,450 2. 105,450 divided by 67 inches = 1573.880 3. 1573.880 divided by 67 inches = 23.49 BMI
- 6. 6 BMI for Overweight,Obesity and Underweight BMI FOR OVERWEIGT INDIVIDUALS: overweight in adults is defined by BMIs of 25.0–29.9 BMI FOR OBESE: obesity by BMIs of 30 or greater.27 A BMI of 30 or greater is roughly equivalent to being 30 or more pounds overweight. BMI FOR UNDERWEIGHT IS 18.5 STANDARD BMI IS 20 TO 25
- 7. 7 Prevalence of Obesity Obesity rates have increased rapidly in the United States in the last two decades. Nearly one-third of U.S. adults have a BMI or 30 or greater with black females having the highest rate (49.6%) and males aged 75 and older the lowest (18.0%). No adult population group meets the Healthy People 2010 target of 15% obesity prevalence. Using the criterion of BMI between 18.5–24.9, only 33% of U.S. Adults are at a healthy weight, down from 51% in 1960 For gender differences in overweight, obesity, and healthy weight.

- 21. 21 CDC Growth Charts Growth charts consist of a series of percentile curves that illustrate the distribution of selected body measurements in children. Pediatric growth charts have been used by pediatricians, nurses, and parents to track the growth of infants.
- 22. 22 Components Of CDCGrowth Charts Weight, stature, length and head circumference are commonly used to assess size and growth. When any of these measures are combined with age or length/stature the result is an anthropometric index (for example, weight-for-age).
- 23. 23 Normal Growth andDevelopment Measurement techniques Growth velocity will slow down during the school-age years Should continue to monitor growth periodically Weight and height should be plotted on the appropriate growth chart
