Obesity is a major lifestyle risk factor associated with non-communicable diseases, such as Type 2 diabetes and cardiovascular disease. Clinicians often monitor Body Mass Index (BMI) to assess these risks.

Table 1 shows clinical measurements for two participants, Participant Y and Participant Z, who are enrolled in a health intervention programme.

Table 1

Participant	Body mass in kg	Height in m	BMI in $kg/m2\text{kg/m}^2$
Participant Y	94	1.85	27.5
Participant Z	93	1.68	$W$

Table 2 shows the standard BMI classifications used by health professionals:

Table 2

BMI Range ( $kg/m2\text{kg/m}^2$ )	Classification
Less than 18.5	Underweight
18.5 to 24.9	Healthy weight
25.0 to 29.9	Overweight
30.0 to 39.9	Obese
40.0 or more	Extremely obese
