[ad_1] Body mass index (BMI) may not increase mortality independently of other risk factors in adults, according to a new study that stressed the need for incorporating other factors. The prevalence of overweight and obesity has risen dramatically over the last 25 years, and it is well-established that elevated BMI can contribute to several cardio-metabolic conditions. However, studies that have analysed the association between BMI and all-cause mortality have been inconsistent. To understand, a team from Rutgers University in the US retrospectively studied data on 554,332 US adults. Of these, about 35 per cent had a BMI between 25 and 30, which is typically defined as overweight, and 27.2 per cent had a BMI above or equal to 30, typically defined as obese. Over a median follow-up of nine years and a maximum follow-up of 20 years, the researchers observed 75,807 deaths. The risk of all-cause mortality was similar across a wide range of BMI categories. For older adults, there w...
