WHO parameters for BMI-for-age parameters are defined by standard deviations and describe overweight to be greater than +1standard deviation from the mean (equivalent to BMI=25 kg/m2 at 19 years) and obese as +2 standard deviations from the mean for 5 to 19 year-olds (equivalent to BMI=30 kg/m2 at 19 years).

During their peak height velocity (the time of most rapid growth), adolescents grow at a growth rate nearly identical to that of a toddler—about 10.3 cm (4 inches) per year for males and 9 cm (3.5 inches) per year for females. [38] In addition to changes in height, adolescents also experience a significant increase in weight (Marshall, 1978).
The number of cases was 57,574, with an average age of 48 years and a median age of 47 years. They were all over 18 years old at the time of the investigation. Regardless of age, urbanity or rurality, ethnic groups, or provinces, the average height of males was 169.60 cm, while the average height of females was 158.88 cm.
The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth ...
A common definition for the onset of puberty is physical changes to a person's body. [13] These physical changes are the first visible signs of neural, hormonal, and gonadal function changes. The age at which puberty begins varies between individuals; usually, puberty begins between 10 and 13 years of age.
Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs.
Human height. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect. It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2][3] or feet and inches when using United States customary units or the imperial system. [4][5] In the early ...
Weight and height percentiles are determined by growth charts and body mass index charts to compare a child's measurements with those of other children in the same age group. By doing this, doctors can track a child's growth over time and monitor how a child is growing in relation to other children. There are different charts for boys and girls ...
