Study Links BMI To Early Death Risk


Study links BMI to early death risk. It has found a strong association between both very high and very low levels of Body Mass Index (BMI) and an increased risk of dying from various major causes. BMI is a measure of your body fat derived from the weight and height of an individual.

Scientists at London School of Hygiene and Tropical Medicine conducted a new research which demonstrated this association and their study was published on Wednesday in The Lancet Diabetes and Endocrinology.

Krishnan Bhaskaran, lead author of the study and associate professor of statistical epidemiology suggests that BMI of between 21 to 25 kg/m2 is linked to the lowest risk of premature death due to cancer and heart disease.

In their study, Bhaskaran and team also found that obesity or BMI of 30 or more was highly associated with an increased prevalence of heart disease and cancer, the two common causes of early death.

Obesity, which can cause other kidney diseases including diabetes, high blood pressure, was found to reduce life expectancy by 4.2 years in men and in women, by 3.5 years.

lead author Krishnan Bhaskaran said, “We found important associations between BMI and most causes of death examined, highlighting that body weight relative to height is linked to risk of a very wide range of conditions. Our work underlines that maintaining a BMI in the range 21-25kg/m2 is linked to the lowest risk of dying from most diseases.”
