A growth chart is used by pediatricians and other health care providers to follow a child's growth over time. Growth charts have been constructed by observing the growth of large numbers of healthy children over time. The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and ...
A review published in the 2007 issue of BJU International showed the average erect penis length to be 14–16 cm (5.5–6.3 in) and girth to be 12–13 cm (4.7–5.1 in). The paper compared results of twelve studies conducted on different populations in several countries.
Reference charts for adult head circumference also generally feature homogeneous samples and fail to take height and weight into account. [ 6 ] One study in the United States estimated the average human head circumference to be 57 centimetres ( 22 + 1 ⁄ 2 in) in males and 55 centimetres ( 21 + 3 ⁄ 4 in) in females.
the ratio of hip circumference to shoulder circumference varies by biological sex: the average ratio for women is 1:1.03, for men it is 1:1.18. [9] legs (floor to crotch, which are typically three-and-a-half to four heads long; arms about three heads long; hands are as long as the face. [10]
For example, a height/weight chart may say the ideal weight (BMI 21.5) for a 1.78-metre-tall (5 ft 10 in) man is 68 kilograms (150 lb). But if that man has a slender build (small frame), he may be overweight at 68 kg or 150 lb and should reduce by 10% to roughly 61 kg or 135 lb (BMI 19.4).
Cephalic index. The cephalic index or cranial index is a number obtained by taking the maximum width ( biparietal diameter or BPD, side to side) of the head of an organism, multiplying it by 100 and then dividing it by their maximum length ( occipitofrontal diameter or OFD, front to back). The index was once used to categorize human beings in ...
The waist–hip ratio or waist-to-hip ratio ( WHR) is the dimensionless ratio of the circumference of the waist to that of the hips . This is calculated as waist measurement divided by hip measurement ( W⁄H ). For example, a person with a 75 cm waist and 95 cm hips (or a 30-inch waist and 38-inch hips) has WHR of about 0.79.
