BMI Not The Only Predictor Of Death

Originally Published November 14, 2008; Last Updated March 14, 2017; Last Republished March 14, 2017:

Researchers conclude that the ratio of waist-to-hip circumferences, in addition to Body Mass Index (BMI), is a risk-predictor of death:
"These data suggest that both general adiposity and abdominal adiposity are associated with the risk of death and support the use of waist circumference or waist-to-hip ratio in addition to BMI in assessing the risk of death."--N Engl J Med 359;20 November 13, 2008--

1 centimeter = 0.3937007874 inch (Online Conversions)

So if your male waist is 42 inches (approx 106 cm) you have 50% greater risk than a male waist of 37 inches (approx 95 cm)—if your female your risk doubles!

Conclusions and Relevance:  "In MZ twin pairs, higher BMI was not associated with an increased risk of MI [myocardial infarction or heart attack] or death but was associated with the onset of diabetes. These results may suggest that lifestyle interventions to reduce obesity are more effective in decreasing the risk of diabetes than the risk of cardiovascular disease or death."

"Racial/ethnic disparities in obesity are apparent in 4-year-old US children. The highest prevalence is in American Indian/Native Alaskan children, in whom obesity is twice as common as in non-Hispanic white or Asian children."--Abstract--
Obesity Among US Urban Preschool Children. Another, earlier study by Whitaker on our chubby children:
"In a sample of preschool children drawn from 20 large US cities, the high prevalence of obesity among Hispanics relative to blacks or whites was not explained by racial/ethnic differences in maternal education, household income, or food security."--Abstract, 2006--

"The prevalence of autopsy-determined coronary atherosclerosis among US service members was 8.5% in our study population. Older age; lower educational level; higher BMI at military entrance; and prior diagnoses of dyslipidemia, hypertension, and obesity were associated with a higher prevalence of atherosclerosis."
Collection of these types of data indirectly point to the potentially significant benefits of systematic and routine autopsies performed by competent, certified and medically trained coroners across all our states and counties (autopsies performed by funeral directors, politicos or farmers etc. are useless).
