Moderate obesity does not shorten life
Mild to moderate obesity (BMI less than 35) does not significantly affect life expectancy. The results of this study, conducted by the American National Center for Health Statistics, are published in open access in the Journal of the American Medical Association (Flegal et al., Association of All-Cause Mortality With Overweight and Obesity Using Standard Body Mass Index Categories. A Systematic Review and Meta-analysis).
Catherine M. Flegal and her colleagues selected all the studies published in recent years that examined the relationship between participants' BMI and mortality from any cause. There were 97 such studies, and a total of 2.88 million people took part in them. 270 thousand of them died in the course of observation.
Meta-analysis of the results showed that in the group of participants with normal weight (BMI 18.5-24.9), as well as in the groups of participants with small (BMI 25-29,9) and moderate obesity (BMI 30-34,9), the overall mortality is approximately the same. In contrast, for participants with a BMI of 35 and above, the risk of premature death increases by 1.29 times.
According to two specialists of the Pennington Biomedical Research Center in Baton Rouge, USA, the results of this meta-analysis prove once again that BMI cannot serve as the only criterion for determining the increased risk of premature death for a patient.
It is also necessary to take into account such "traditional" factors as high blood pressure, blood lipids and glucose concentration, as well as concomitant diseases and heredity.
And the main factor, not taken into account by the authors of the titanic work described above and noticeably reducing the value of their conclusions, is shown in the figure below – VM.
