In India, the incidence of obesity in women is far higher than men for many reasons, one being their physiology and the other being their child-bearing. Likewise, for obese women risk factor is much higher than men. Nothing is impossible in the world; proper diet and consistent aerobic exercise can reduce the risk considerably.
Many research studies on obesity-related issues have been pouring out information on the close link between obesity and the waist line. A new study undertaken by the medical researchers at
the University of Iowa, USA has come up with new results: the researchers point out that some people having normal health and weight, without knowledge could be at high risk for obesity-related health problems. It implies they are ignorant of their inherent /hidden obesity related risks.
the Journal of the American Medical Association's Network Open.
Normally body mass index (BMI) is measured in such studies as a standard procedure. The study points that a subgroup of people having normal weight based on their BMI may run the risk of death provided they have large waist-line.
According to the main author as per current clinical guidelines, physicians have to depend on BMI to determine obesity-related health risks. The crux of the matter is this method excludes those who are actually in a high-risk group because of other risk factors, such as percentage of body fat. Such people think that they 're healthy.
This study used the data collected by the Women's Health Initiative from more than 156,000 women between the ages of 50 and 79 from 1993 to 2017. They tracked the mortality rates and the link to the respondents' BMI as well as their central obesity. Central obesity, that is excess accumulation of fat around a person's midsection is an important criterion in this unique study. The parameter is not given due importance. From this research, it is imperative, central-obesity is an essential factor in the study of obesity-health related issues.
The study demonstrates the limitations of BMI when determining a person's risk for health problems. A person's weight and height alone can not determine his health issue so is normal BMI. The latter does not show the distribution of body fat and its accumulation in one place. BMI is widely used in obesity related issues, but this parameter pushes the people with central obesity in the dark and the risk is not addressed.
The research group's conclusion is : "People with normal weight based on BMI, regardless of their central obesity, were generally considered normal in clinical practice according to current guidelines," Bao says. "This could lead to a missed opportunity for risk evaluation and intervention programs in this high-risk subgroup."
