什么是BMI?
BMI is calculated using weight 和 height measurements 和 is an estimator of body fat. It is not a direct measurement of fat, but research has shown that BMI measurements correlate to direct measurement. It’s an inexpensive 和 easy-to-perform way to screen for possible weight. BMI is measured differently in adults than in children, so it is important to use the proper calculator to find out yours 和 your child’s separately.
BMI is not used to diagnose health issues, but it can be an early screening tool. Your child’s health care professional may use additional information, 比如家族史, information about diet 和 exercise or a measurement of skinfold thickness or other tests to determine whether excess fat is a problem.
You can find your child’s BMI by entering their height 和 weight into this online BMI calculator for children 和 teens from the Centers for Disease Control.
我孩子的BMI是什么意思?
适合儿童和青少年, BMI is evaluated using age- 和 sex-specific charts that considers the different growth patterns for the sexes. Weight 和 the amount of fat in the body differ for boys 和 girls, 和 those levels change as they grow taller 和 older.
这些图表 help health care professionals determine how a child’s particular BMI reading compares to the readings of other U.S. 同龄儿童. The group is divided into percentiles that reflect whether a child is at a healthy weight, 体重过轻, 超重或肥胖.
Children over age 2, or teens whose BMI is:
- Less than the 5th percentile are considered 体重过轻.
- Between the 5th percentile 和 less than the 85th percentile are at a healthy weight.
- In the 85th percentile to less than the 95th percentile are considered overweight.
- Equal to, or greater than the 95th percentile are considered obese.
