A new Canadian review of research on the relationship between weight and risk of premature death finds that having a body mass index in the underweight range is linked to an even higher risk of death than having a body mass index in the obese range.
Led by Dr. Joel Ray, a physician-researcher at St. Michael’s Hospital, University of Toronto, the review is published in the Journal of Epidemiology and Community Health.
In their review, Dr. Ray and colleagues found that adults with a BMI classed as underweight (under 18.50 or less) had a 1.8 times higher risk of dying from any cause than adults with a BMI classed as normal. This was even higher than for people classed as obese.
For people with a BMI in the range 30.00 to 34.99 (obese), the risk of dying was 1.2 times higher than that of people with BMI classed as normal, and for those with a BMI higher than 35.00 (severely obese), the risk was 1.3 times higher.
