Question

C. Body Mass Index (BMI) is a measure expressing the relationship of weight to height that is correlated with fatness. I'd like you to practice using the CDC's BMI percentile calculator for kids/teens. Using this link, https://nccd.cde.gov dnpabmi Calculator.aspx please calculate BMI using the following information: sr rollowing informations hit esllneed ede govidapabmlCalculator.asps plcease Birth date: May 10, 2006 Date of measurement: February 26, 2018 Sex, height, and weight: Girl, 5 Feet 1 inch, 122 pounds After entering this information, you will be presented with the BMI results. Please report the following information: What is the child's BMI: a) b) c) What is their BMI-for-age-percentile? Are they underweight, "normal" weight, overweight, or obese? d) What advice could you, as a practitioner. provide the child's parents in an effort to improve their health? e) Using either the course textbook, the CDC's site, or another reputable resource, or prior knowledge, please explain why a person's BMI might not be the best indicator of their health.

Explanation / Answer

A)Based on the height and weight entered, the BMI is 23.1.

B)Placing the BMI-for-age at the 91st percentile for girls aged 11 years 9 months.

C)The child is overweight.

D)Encourage children and teens to practice healthy weight habits by

i)Eating healthy foods and beverages include water.

ii)Getting adequate sleep.

iii)Limiting television viewing.

iv)Participating in physical activity on most(preferably all) days of the week.

E)i)BMI Doesn’t Take Gender into Account

If a man and woman are the same height and weight, they have the same calculated BMI. The problem is women have a higher body fat percentage than men. On average, a man and woman of similar height and weight might have a body fat percentage that differs by 10% or more. Based on BMI, a man with 15% body fat and a woman with 30% body fat are at similar risk based on BMI. However, a body fat percentage of 30% or above in a woman is higher than what would theoretically be ideal for health.

ii)BMI Doesn’t Take into Account WHERE You Store Fat

Two people with different body fat percentages can have the same BMI, as long as their height and weight are the same. BMI as a measurement also doesn’t take into account body fat distribution. Studies now show that where you carry your body fat matters and you’re at higher risk of health problems if you store a higher proportion of body fat around your waist and tummy.

In contrast, fat stored around the hips and thighs doesn’t appear to carry the same risk. In fact, deep tummy fat is a marker of insulin resistance and poor metabolic health. So, two people can have the same BMI, yet one will be at higher risk of type 2 diabetes and heart disease because of where they store their fat.

iii)It Doesn’t Take Into Account Bone Mass

Bone is denser than muscle and muscle is denser than fat. So, if you have large, strong bones, your BMI will be higher than someone with a small bones or a lower bone density, assuming everything else is equal. However, having strong bones is a benefit in terms of future health risks. You’re less likely to suffer a debilitating hip fracture if you have a higher bone density

iv)BMI Doesn’t Consider Age

When you calculate the BMI of an older adult, they may fall into the normal category yet be sarcopenic with significant loss of muscle tissue. Their BMI is normal because it only takes into consideration total body weight and height. Yet, a sarcopenic man or woman might be overweight or obese in terms of body fat percentage alone but their BMI doesn’t reflect it. Older people with normal BMIs may still have excess body fat and loss of muscle tissue that places them at risk.

v)It Doesn’t Take into Account Ethnicity

Some ethnicities have naturally smaller frames. For example, a male or female of Japanese ethnicity could have a much smaller frame than a Caucasian, Hispanic, or African American. So, if a Japanese male or female has the same BMI as a Caucasian one, they may have significantly more body fat to achieve that BMI as their bone and frame size are smaller.

vi)BMI Isn’t Reliable for Athletes

What if you strength train and increase your muscle mass? You’re strong, toned, and exceptionally fit. Yet, when your doctor measures your BMI, you fall smack dab into the overweight category. This scenario isn’t uncommon and it reveals another weakness of BMI as a measure. Any time your weight increases, whether through gains in muscle or gains in body fat, your BMI goes up. As an article in New Scientist pointed out, some of the Olympic level athletes fall into the overweight category. So, BMI is particularly unreliable for men and women who are highly fit and athletically trained.
