What is the theory of BMI?

Body mass index (BMI) is a measure of weight adjusted for height, calculated as weight in kilograms divided by the square of height in meters (kg/m2). Although BMI is often considered an indicator of body fatness, it is a surrogate measure of body fat because it measures excess weight rather than excess fat.

How might a sociologist explain obesity in the US?

Unlike the physically disabled, the obese are held responsible for their condition.

What study is BMI based on?

Instead, Keys et al, using better documented weight for height data, popularized the Quetelet Index in population-based studies. They referred to it as the body mass index (BMI). Thus, Quetelet Index = body weight (kilograms) divided by height squared (meters) = BMI.

Who invented BMI scale?

What is better than BMI?

Waist-to-height ratio (WHtR) WHtR is more accurate than BMI because it takes central fat into consideration. Central fat is important because it collects around the organs in your midsection and has been closely linked to conditions such as heart disease.
