BMI - Death correlation exists - irrespective of your race
A new study was just published exploring the association of body-mass index (BMI) and risk of death.
This study showed that in an Asian population, there exists the same U-shaped curve that exists in individuals of European decent. This U-shaped curve reveals that there is higher rates of death the more extreme deviation from "normal" weight - both on the high side and the low side. Individuals with very low weight and very high weight have much increased risk of death compared with "normal" weight individuals.
This study also showed that the same BMI criteria for overweight (BMI >25 kg/m2) and obese (BMI >30 kg/m2) could be applied to an Asian population as is applied to a population of European decent.
How does one calculate their BMI? Its easy, just use one of the readily available online calculators. Or use a BMI chart.
As the researchers state "The main message is that people must be encouraged to maintain a normal weight: too low and too high are both unhealthy. To do this, people must eat healthily, do more exercise, and not smoke."
