UNITED STATES (OBSERVATORY) – It is considered that a fat person is automatically at risk and is more likely to be a victim of a disease than his friend, leading an active lifestyle. This is not always so, says an employee of the British University of Loughborough, William Johnson, reports Eureka Alert .
Johnson says that people with the same body mass index can have different health indicators, which are not necessarily associated with excess weight. The scientist recalls the concept of “healthy obesity”, which was introduced in the 1980s to describe people who are overweight who did not suffer from hypertension or diabetes.
However, until recently ignored the fact that people falling into this category on health indicators (body mass index (BMI) is more than 30 kilograms per square meter, blood pressure is less than 140 per 90), can both suffer from obesity and possess normal weight. The state of health of such people with a certain similarity will also be different.
Johnson emphasizes that in research it is important to consider other factors besides BMI.
“It’s important to know how long a person has been obese, whether he smokes and for how long, these data will help explain why people with the same BMI have different life expectancies,” the scientist believes.
According to recent studies, in the United States, New Zealand, Iceland and Greece, 90 percent of adult men and 50 percent of children have extra fat.
