BODY MASS INDEX --BMI

BMI = 22.96 kg/m2   (Normal)
  • Normal BMI range: 18.5kg/m2 - 25 kg/m2
  • Normal BMI weight range for the height: 128.9lbs - 174.2 lbs
  • Ponderal Index: 12.91 kg/m3

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.

CategoryBMI range - kg/m2
Severe Thinness< 16
Moderate Thinness16 - 17
Mild Thinness17 - 18.5
Normal18.5 - 25
Overweight25 - 30
Obese Class I30 - 35
Obese Class II35 - 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.

CategoryPercentile Range
Underweight<5%
Healthy weight5% - 85%
At risk of overweight85% - 95%
Overweight>95%

Ponderal 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

The Anatomy Act of 1832

Prior to 1832, only the corpses of executed murderers were allowed to be dissected in the UK, but with the rise of medical science and the scaling back of executions, demand came to outstrip supply. The British Anatomy Act, passed in response to public concern about the illegal trade in corpses, was an act of Parliament that increased the supply of cadavers legally available for medical research and education. What were "resurrectionists," and how were they impacted by the Anatomy Act? More... Discuss

Tennis Player Arthur Ashe Announces He Has AIDS (1992)

Ashe was the first African-American male to reach prominence in tennis and was thus a very public figure, even after his retirement, which followed a 1979 heart attack and quadruple-bypass surgery. In 1983, he contracted HIV from a blood transfusion during a second heart surgery. He kept it a secret until 1992, when a newspaper threatened to publish a story about his illness. His subsequent openness about AIDS helped combat the disease's stigma. How much longer did Ashe live? More... Discuss

Sonja Henie (1912)

Henie began ice skating at the age of eight and won the first of six straight Norwegian figure-skating championships within two years. Starting in 1927, she won the world's figure-skating crown 10 straight years, the European title six times, and the Olympic gold medal three times. She introduced music and dance into free skating, greatly broadening its appeal, and turned professional in 1936, earning millions starring in films and ice shows. Why did many Norwegians consider her a quisling? More... Discuss

Today's Holiday

Hana Matsuri

Hana Matsuri is a celebration of the Buddha's birthday, observed in Buddhist temples throughout Japan, where it is known as Kambutsue. The highlight of the celebration is a ritual known as kambutsue ("ceremony of 'baptizing' the Buddha"), in which a tiny bronze statue of the Buddha, standing in an open lotus flower, is anointed with sweet tea. People use a small bamboo ladle to pour the tea, made of hydrangea leaves, over the head of the statue. The custom is supposed to date from the seventh century, when perfume was used, as well as tea.
