While it is helpful to use medical information to gauge how close you are to the appropriate weight for your age, many factors influence how close the weight of a 17-year-old male is to the ideal.
To compare the weight of a 17-year-old male to an appropriate weight according to medical height/weight charts, you must first calculate the adolescent's body mass index (BMI). This is because ideal weight is a function of the child's height, and a BMI calculator takes both height and weight into account.
Use an online BMI calculator to calculate the body mass index of the child. Then, using a medical growth chart for males, locate 17 along the X-axis and follow the line to determine whether he falls within a healthy range. The median BMI index for a 17-year old-male is 22. If the BMI value falls under the 5th percentile, the individual is considered underweight. A BMI above the 95th percentile indicates the child is overweight.
Maintaining a healthy weight helps prevent diseases associated with being overweight, including high blood pressure and high cholesterol. Awareness of how BMI compares to that of a healthy 17-year-old adolescent helps doctors treat or prevent these disorders.
