Measurement of BMI
Transcription
Today's lesson is about different methods of assessing body mass index (BMI). These methods include body weight, BMI, waist circumference, body fat measurement, spondyloid index, waist to hip ratio, and brocade index. BMI is considered a better estimate of body fat than just body weight. It is calculated by dividing weight in kilograms by height in meters squared. Based on the BMI value, obesity is classified into different grades. A value over 40 is grade 3 obesity, 30-40 is grade 2, and 25-29.9 is grade 1. A value between 18.5 and 24.9 is considered normal, and below 18.5 is undernourished or malnourished. Good evening everyone. Today we will learn about the different methods of assessment of body mass index. So the ways by which we can assess obesity include body weight, body mass index, waist circumference, measurement of body fat, spondyloid index, waist to hip ratio and brocade index. Coming to the measurement of body mass index, it is one of the accepted tools and understood as a better estimate of body fat mass and surplus than body weight. It is also known as the tutelage index. This index does not require any standard tables. So BMI is calculated by taking the weight of the individual in kg to the height measured in meter square. Based on the values obtained, the obesity is classified as, if the values are greater than 40, they are graded as grade 3 obesity and if the values fall between 30 to 40, graded as grade 2 and if the values are between 25 to 29.9, they are categorized under grade 1 obesity. If the BMI value is between 90 to 25, they are considered as normal individuals and if the BMI goes less than 90, they are classified as undernourished or malnourished. Thank you.
