Self-test method of fat

AThe following methods, you can measure the threshold of the ranks of the obese.
Body mass index or body fat index
Calculated as follows: use of body weight (kg) divided by height squared (m2). The number

of results in between 18.5 to 24 is normal, and less than 18.5 for a bit thin, for more

than 24 partial fat. Comparison of this method applied to ordinary adults, for children,

is not particularly accurate. Children of all ages because the body mass index is

different at different stages of growth there will be ups and downs. Even a 18-year-old

from birth to have a normal weight children, and his body mass index is not stable at a

level of total online. 1-year-old child when the highest body mass index, and then begin

to decline, the 67-year-old began to rebound in the adiposity rebound period, then

gradually increased, close to adult standards. The same body mass index for children of

different ages, different meaning. Such as body mass index of 22, for sixteen or

seventeen-year-old children is within the normal range, and for a 5-year-old child is

already obese by. Therefore, body mass index to determine obesity is not the most accurate

tool, but it could serve as a judge early.
Need to remind parents that if their children's body mass index over 24, regardless of his

age group in which are certainly beyond the normal scope.
Body Composition Testing
Devoted to measuring the body fat is the number of specialized agencies need to detect,

but also higher cost.
People from many parts of the body weight of the composition, and bone, water, muscle, fat

and so on. Detection of body mass index is the relationship between body weight and

height, is not devoted to measuring the body fat content. For example, an athlete and a

person who never campaigns and their body mass index, but their fat content is not the

same as, athletes of the fat content than those who never much less movement. People are

obese because excessive accumulation of body fat. Detection is the measurement of body

composition of fat, such detection for more accurate measurement of obesity, more

targeted. If you suspect that your child obese, you can take him to the detection of body

composition to determine whether high fat content.
Mothers need to be reminded that women are sometimes prone to obesity occult. Some women

do not look fat, body mass index is not high, but a body composition test and found that a

high fat content, the occult found obesity more difficult.
The ratio of waist circumference and height
Measuring the ratio of waist circumference and height, but also can be used as abdominal

obesity criteria. Usually the ratio of waist height and should not be more than 0.46, that

is, waist circumference should be less than half the height. The advantage of this

indicator do not have to consider the factors age and height.
Waist
The provisions of our country, adult male waist circumference less than 90 cm, adult

females 80 cm for waist circumference less than normal.
