Half of the women who are fat do not have a high BMI – March 2012

BMI was found to categorize as healthy when actually have high amount of fat

  • 25% of men
  • 48% of women

Background on Body Mass Index at BMI – WikiPedia

  • BMI became a standard by 1850 – more 160 years ago
  • Has been known for a long time that BMI is easy to calculate but serves only as a vague means of estimating adiposity.
  • Additional indexes described in WikiPedia include:
    Body volume index; Waist-hip ratio; Sagittal Abdominal Diameter (SAD); Body fat percentage
    Body water; Allometric law; Ponderal index; Rohrer's index
  • BMI does not take into account many factors such as: frame size, muscularity, varying proportions of fat, bone, cartilage, water weight

Obesity is a serious disease that is associated with an increased risk of diabetes, hypertension, heart disease, stroke, and cancer, among other diseases. The United States Centers for Disease Control and Prevention (CDC) estimates a 20% obesity rate in the 50 states, with 12 states having rates of over 30%. Currently, the body mass index (BMI) is most commonly used to determine adiposity. However, BMI presents as an inaccurate obesity classification method that underestimates the epidemic and contributes to failed treatment. In this study, we examine the effectiveness of precise biomarkers and duel-energy x-ray absorptiometry (DXA) to help diagnose and treat obesity.

Methodology/Principal Findings
A cross-sectional study of adults with BMI, DXA, fasting leptin and insulin results were measured from 1998–2009. Of the participants, 63% were females, 37% were males, 75% white, with a mean age = 51.4 (SD = 14.2). Mean BMI was 27.3 (SD = 5.9) and mean percent body fat was 31.3% (SD = 9.3).
BMI characterized 26% of the subjects as obese, while DXA indicated that 64% of them were obese. 39% of the subjects were classified as non-obese by BMI, but were found to be obese by DXA. BMI misclassified 25% men and 48% women. Meanwhile, a strong relationship was demonstrated between increased leptin and increased body fat.

Our results demonstrate the prevalence of false-negative BMIs, increased misclassifications in women of advancing age, and the reliability of gender-specific revised BMI cutoffs. BMI underestimates obesity prevalence, especially in women with high leptin levels (>30 ng/mL). Clinicians can use leptin-revised levels to enhance the accuracy of BMI estimates of percentage body fat when DXA is unavailable.
