BODY MASS INDEX --BMI
BMI = 22.96 kg/m2 (Normal)
The Body Mass Index (BMI) Calculator takes age into consideration when calculating the BMI value and weight status of that individual. Below is a referenced weight range and calculation formula.
Reference
It should be noted that BMI measures your body weight based on your height and weight. Your BMI does not actually "measure" your percentage of body fat, but it helps to estimate a healthy body weight based on a person’s height. A person’s BMI "number" can serve as an indicator that a person is underweight, normal weight, overweight, or obese. Note that body types, the distribution of muscle and bone mass varies among individuals. Therefore BMI should not be the only or final indicatior for diagnosing the weight stsatus of an individual.
Body Mass Index Formula
The formulas to calculate BMI based on two of the most commonly used unit systems:
-
BMI = weight(kg)/height2(m2) (Metric Units)
BMI = 703·weight(lb)/height2(in2) (U.S. Units)
BMI Table for Adults
This is the World Health Organization's (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older.
| Category | BMI range - kg/m2 |
| Severe Thinness | < 16 |
| Moderate Thinness | 16 - 17 |
| Mild Thinness | 17 - 18.5 |
| Normal | 18.5 - 25 |
| Overweight | 25 - 30 |
| Obese Class I | 30 - 35 |
| Obese Class II | 35 - 40 |
| Obese Class III | > 40 |
BMI Table for Children and Teens, Age 2-20
The Centers for Disease Control and Prevention (CDC) recommends BMI categorization for children and teens between age 2 and 20.
| Category | Percentile Range |
| Underweight | <5% |
| Healthy weight | 5% - 85% |
| At risk of overweight | 85% - 95% |
| Overweight | >95% |
CDC GROWTH CHARTS

CDC CHARTSPonderal Index
Similar to BMI, the Ponderal Index (PI) is a measure of leanness of a person. It was also called Rohrer's index. Comparatively, the Ponderal Index is more even for different stature. Therefore, it was commonly used in pediatrics.
-
PI = weight(kg)/height3(m3) (Metric Units)

Normal Lab Values and Vital signs -- USMLE
USMLE Step 2 CS
Vital signs
Vital signs include your heart beat, breathing rate, temperature, and blood pressure. A healthcare provider will measure, or monitor your vital signs to determine your level of physical functioning. Note that the normal vital signs varies with age, sex, weight, exercise tolerance, and your overall health.
These are the normal vital sign ranges for a resting, average healthy adult
- Blood pressure: 90/60 mm/Hg to 120/80 mm/Hg
- Breathing: 12 - 18 breaths per minute
- Pulse: 60 - 100 beats per minute
- Temperature: 97.8 - 99.1 degrees Fahrenheit / average 98.6 degrees Fahrenheit

 World Trade Center Opens in New York City (1973)With seven buildings and a shopping concourse, the World Trade Center in lower Manhattan was the largest commercial complex in the world before it was destroyed in the September 11, 2001, terrorist attacks. Its most prominent structures were the 110-story rectangular Twin Towers, which, at more than 1,360 ft (415 m) tall, were the tallest buildings in the world until the Sears Tower surpassed them in 1974.
