Table 4. Association of systolic blood pressure, body mass index, and waist circumference in main phase and the rate of their change from main phase to repeated measurement with chronic kidney disease defined as eGFR < 60 ml/min/1.73m2.
| Crude OR | Adjusted OR* | Adjusted OR* | |
|---|---|---|---|
| SBP at baseline | 1.19 (1.17–1.22) | 1.07 (1.04–1.10) | 1.07 (1.04–1.10) |
| Rate of change in SBP | 1.65 (1.49–1.82) | 1.20 (1.09–1.33) | 1.20 (1.07–1.33) |
| BMI at baseline | 1.05 (1.04–1.06) | 1.02 (1.01–1.03) | - |
| Rate of change in BMI | 1.06 (0.97–1.16) | 1.20 (1.09–1.32) | - |
| Waist at baseline | 1.01 (1.02–1.03) | - | 1.01 (1.01–1.02) |
| Rate of change in waist | 1.11 (1.08–1.15) | - | 1.08 (1.04–1.11) |
SBP: Systolic Blood Pressure; BMI: Body Mass Index; ORs are reported for each 10 mmHg increase in baseline SBP, each 10 mmHg increase in SBP per year, and each one unit increase in baseline BMI or waist circumference and each one unit increase per year.
*In multivariate models, ORs are adjusted for: sex, age, residence, literacy, history of self-reported cardiovascular disease and diabetes at baseline, opium use at baseline, taking anti-hypertensive medications and blood glucose lowering medications at baseline
