• Sample Size: 30,000 participants.

Step 1: Socio-Demographic and Behavioral Information

Tobacco Use

• Prevalence of raised BP (SBP ≥ 140 or DBP ≥ 90): 16.09% (95% CI: [15.39, 16.82]) (Overall)
• Hypertension Stage 2 (SBP ≥ 170 or DBP ≥ 100): 6.12% (95% CI: [5.75, 6.52]) (Overall)

Summary of Combined Risk Factors (Non-communicable Disease Risk Factors)

• Key Risk Factors:

  1. Current daily tobacco use
  2. Fruit/vegetable intake < five servings/day
  3. Sedentary lifestyle (physical activity <600 MET-min/week)
  4. Overweight/obesity (BMI ≥ 25 kg/m²)
  5. Raised blood pressure (SBP ≥ 140 or DBP ≥ 90)

• Low Risk (none of the above): 3.27% (95% CI: [2.788, 3.839]) (Overall)

• Raised Risk (≥3 factors):

  • Age 15-44: 21.64% (95% CI: [20.67, 22.65]) (Overall)
  • Age 45-64: 52.87% (95% CI: [51.11, 54.62]) (Overall)
