Y1 - 2021 N1 - T2 - Decision Making in Perioperative Medicine: Clinical Pearls AB - Obesity is a prevalent medical comorbid condition and its incidence has tripled worldwide since 1975. In 2018, an estimated 42% of Americans were considered obese, with 9.2% being classified as severely obese.1 Obesity accounted for 480 billion dollars in U.S. Healthcare spending in 2016 and more recent estimates are considerably higher.2 The Body Mass Index (BMI), a person’s weight in kilograms divided by the square of height in meters, is the most commonly accepted measure of obesity. In general, morbid obesity is defined as a condition that results from an abnormally high body mass that is diagnosed by having a BMI greater than 40 kg/m², a BMI of greater than 35 kg/m² with at least one serious obesity-related condition, or being more than 100 pounds over ideal body weight (IBW). See Table 29-1 for BMI and obesity classifications. SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/03/29 UR - accessmedicine.mhmedical.com/content.aspx?aid=1179531610 ER -
