New Study: High BMI Poses Health Risks for Both Smokers and Non-Smokers
A groundbreaking study published in The Lancet in 2016 has highlighted the significant health risks associated with higher Body Mass Index (BMI) for both smokers and non-smokers. BMI, a common measure of body composition, was found to be linked to increased risks of cancer, heart disease, and stroke, even in individuals who have never smoked.
The study, which combined data from 239 clinical studies, revealed that in smokers, an increased BMI was associated with all-cause mortality. This means that even for those who smoke, maintaining a healthy weight is crucial for overall health.
BMI, calculated as weight per meter of body surface area, is widely used as an approximation of body composition, particularly total body fat. However, it's important to note that BMI may not accurately represent body mass in individuals with high muscle mass.
Another measurement that can help determine whether someone is at a healthy body weight is waist circumference. For adults, the BMI scale ranges from under 18 (underweight) to above 40 (class III obesity), with normal weight considered to be between 18-25.
The Lancet study underscores the importance of maintaining a healthy weight, regardless of smoking status. While BMI is a useful tool, it's essential to consider other factors like muscle mass and waist circumference for a more comprehensive understanding of body composition and health risks.
