What is the meaning of bmi ?

Body mass index: The categories normal, overweight, and obese are defined by the body mass index (bmi), which is a measurement that looks at one's weight in comparison to her height. Tall people are allowed to weigh more than short people are. Bmi calculators are available at the doctor's office and also on the internet. An adult with a BMI of 18.5-24.9 is normal, 25-29.9 is overweight, and 30 or more is obese.

Body Mass Index: It si a factor of your height and weight.

Here's a website: http://www.bmicalculator.org/ has explanations and calculators for men an women. Calculations require height, weight, gender and, in kids, age. The result is a %ile that indicates whether your weight is healthy for your height. If >95th%ile, see your doctor to reduce your risk of diabetes, heart disease and other medical complications of obesity.

Weight:height.: The BMI is simply your weight with respect to your height - an overly simplistic and thereby essentially flawed assessment of your health. It's a bit better when used in combination with body fat measurement. That being said, a high BMI might be associated with diabetes and heart disease amongst other health conditions.
