A new study shows that too high or low body mass index measurements are linked towards an increase in the risk of dying from almost all major causes, except for road accidents. The study has been published on Wednesday in The Lancet Diabetes and Endocrinology. It was conducted by scientists at the London School of Hygiene and Tropical Medicine. The research went on to reveal that either too high or too low level of BMI is connected towards an increase in morbidity from a wide range of major diseases. The lead author of the study, Krishnan Bhaskaran noted that his team found important connections between BMI and the maximum causes behind the death. BMI is certainly a key indicator of health. He said that his team is aware of the fact that BMI is linked to the overall risk of dying. He is even surprised that very little research has got conducted on the links related to deaths from specific causes.
Bhaskaran even said that his team has managed to fill the knowledge gap to assist researchers, patients and doctors greatly. One can determine BMI by dividing the weight of a person in kilograms by square of their height in metres. The authors of the study say that they have discovered that maintaining a BMI within the range of 21 to 25 kg/m2 is clearly linked to the lowest level of morbidity. The lead author said that when BMI is higher than 25, then it is linked towards a maximum number of cancers, maximum cardiovascular diseases, respiratory problems, along with liver and kidney diseases. The problem of obesity was shown to reduce life expectancy by 4.2 years in men and 3.5 years in women. It can even lead to other chronic conditions related to liver disease, diabetes and respiratory disorders.
Finally, Bhaskaran said that it is important to maintain a Body Mass Index within the range of 21 to 25. The results highlighted that, if one maintains a BMI of 25 kg/m2, then it carries the lowest risk of death due to heart disease. The lowest risk of death due to cancer was proved to be at a BMI of 21 kg/m2.
