Today, almost 20% of teens are obese or overweight. Why is it important to lower that number? A. Because obese/overweight teens are more likely to become obese/overweight adults B. Obese/overweight teens will have more diseases and shorter life spans C. Obese/overweight people will cost our country more money in health care. D. All of the above

ody mass index (BMI) is a measure used to determine childhood overweight and obesity. Overweight is defined as a BMI at or above the 85th percentile and below the 95th percentile for children and teens of the same age and sex. Obesity is defined as a BMI at or above the 95th percentile for children and teens of the same age and sex.

BMI is calculated by dividing a person’s weight in kilograms by the square of height in meters. For children and teens, BMI is age- and sex-specific and is often referred to as BMI-for-age. A child’s weight status is determined using an age- and sex-specific percentile for BMI rather than the BMI categories used for adults. This is because children’s body composition varies as they age and varies between boys and girls. Therefore, BMI levels among children and teens need to be expressed relative to other children of the same age and sex.

For example, a 10-year-old boy of average height (56 inches) who weighs 102 pounds would have a BMI of 22.9 kg/m2. This would place the boy in the 95th percentile for BMI, and he would be considered as obese. This means that the child’s BMI is greater than the BMI of 95% of 10-year-old boys in the reference population.

The CDC Growth Charts are the most commonly used indicator to measure the size and growth patterns of children and teens in the United States. BMI-for-age weight status categories and the corresponding percentiles were based on expert committee recommendations and are shown in the following table.

BMI-for-age weight status categories and the corresponding percentiles  

Weight Status CategoryPercentile Range

UnderweightLess than the 5th percentile

Normal or Healthy Weight5th percentile to less than the 85th percentile

Overweight85th to less than the 95th percentile

Obese95th percentile or greater

BMI does not measure body fat directly, but research has shown that BMI is correlated with more direct measures of body fat, such as skinfold thickness measurements, bioelectrical impedance, densitometry (underwater weighing), dual energy x-ray absorptiometry (DXA) and other methods1,2,3. BMI can be considered an alternative to direct measures of body fat. A trained healthcare provider should perform appropriate health assessments in order to evaluate an individual’s health status and risks.

Explanation:

The answer is D.

Explanation:

Obese/overweight teens are more likely to become obese/overweight adults and will have more dieseases and a shorter life span which causes our countrey to spend more on Healthcare
