Dependent Variable: Diabetes Risk: High diabetes risk (IDRS ≥ 60); reference category = Low to moderate risk (IDRS < 50).
Primary Independent Variable: (a) Body Mass Index (BMI): Normal Weight; Overweight; Obese; Underweight (ref).
Second Independent Variable/s in the models: (1) Wealth Index: Poorest (ref); (2) Caste: SC (ref); (3) Education Level: Diploma, graduate and other higher qualification (ref); (4) High Blood Pressure: <140 mmHg systolic, < 90 mmHg diastolic blood pressure (ref); (5) Heart disease or Stoke: No (ref).
ref = Reference Category; AOR = Adjusted Odds Ratio; CI = Confidence Interval; ST = Scheduled Tribe; OBC = Other Backward Classes; SC = Scheduled Caste.
