Running head: BODY MASS INDEX 1 Body Mass Index Tool and Assessment Whitney Smith Walden University NURS 6512, Section 38, Advanced Health Assessment September 11, 2019
BODY MASS INDEX 2 Body Mass Index Tool and Assessment Less than two percent of adults over age 20 reports underweight, and 71.6 percent are overweight, including obesity (Centers for Disease Control and Prevention, 2019). The small percentage of adults that live with a healthy weight and lifestyle is continuing to decline. In the early 19th century, a mathematician produced a formula for a person to measure the degree of obesity. This reasonable measure of body fat has proved to conduct misleading results in specific populations. Body Mass Index (BMI) remains one physical measurement screening tool that can help identify whether an adult is at a healthy weight (Nuttall, 2015). The purpose of this paper is to describe the BMI tool and its relation to use in healthcare today. The purpose of the instrument, how it is conducted, and the information it gathers will be discussed. The validity and reliability of this tool will be evaluated, and issues regarding sensitivity, reliability, and predictive values will be noted. BMI Use In Healthcare The BMI tool is a simple calculation of fat measurement but is to be aware that it is not a diagnosis. BMI catergories may indicate the need for additional testing to ensure that excess fat or malnourishment is not a posing risk to the health status of an individual. A BMI that is too low can indicate inadequate caloric intake, lack of vitamin and minerals, the risk for low energy, and weak immunity. Higher than normal weight values may indicate obesity followed by high blood pressure, diabetes, and high risk for disease such as heart disease (CDC, 2019). Many Americans use the BMI tool at home to categorize themselves, but healthcare facilities have veered away from using this measurement for the adult population. Mayo Clinic uses the tool but adds in the circumference of the waist measurement because it is an indirect way of gauging body fat and can put one at risk for obesity-related conditions (Mayo Clinic, 2019).
