Obesity is a major lifestyle-related risk factor for several non-communicable diseases, including Type 2 diabetes and coronary heart disease.

Table 1 shows physiological data collected from two participants in a clinical trial monitoring metabolic health.

Table 1

Subject Y741.5530.8
Subject Z911.76XXX

Table 2 shows the clinical classification of Body Mass Index (BMI) and its corresponding risk level for Type 2 diabetes:
