Regression Models of the Relationship Between Changes in Each Individual Lifestyle Component and SBP Measured in the Clinic and by Ambulatory Blood Pressure Monitoring
| Changes in targeted lifestyle modifications | Clinic SBP | Ambulatory SBP | ||
|---|---|---|---|---|
| b | 95% CI | b | 95% CI | |
| Change in weight, 2.5 kg | 2.04a | 1.06–3.02 | 2.01a | 1.00–3.03 |
| Change in fitness, 10% peak VO2 | 3.14a | 2.12–4.17 | 2.35a | 1.26–3.45 |
| Change in DASH score, two points | 4.93a | 2.68–7.18 | 4.06a | 1.72–6.40 |
| Change in dietary sodium, 1000 mg/d | 3.08b | 0.67–5.48 | 4.54a | 2.21–6.87 |
Abbreviations: b, beta coefficient; CI, confidence interval; DBP, diastolic blood pressure; SBP, systolic blood pressure. Models adjusted for age, race (African American or other), sex, preintervention blood pressure, baseline estimated glomerular filtration rate, and the preintervention level of the predictor. Ambulatory models also adjusted for percent of measurements in the seated or supine position. Changes in intervention components were scaled using the following increments: weight by 2.5 kg, fitness by 10% of peak oxygen uptake (VO2), Dietary Approaches to Stop Hypertension (DASH) score by two‐point increments, and dietary sodium by 1000 mg/d. a P<.001. b P<.02.
