Change in systolic blood pressure among preplanned subgroups
| Characteristic | 12-month change in SBP, Mm Hg, mean (SEM) | Difference in change PL − ES (95% CI) | |
|---|---|---|---|
| PL | ES | ||
| Uncontrolled HTN | −8.0 (1.6) | −12.0 (1.6) | 4.0 (−0.5 to 8.4) |
| Controlled HTN | −0.5 (1.3) | 1.6 (1.6) | −2.1 (−6.2 to 2.0) |
| Body mass index <30kg/m2 | −2.7 (1.5) | −6.1 (1.8) | 3.4 (−1.3 to 8.0) |
| Body mass index ≥30kg/m2 | −4.3 (1.6) | −5.2 (1.6) | 0.9 (−3.6 to 5.4) |
| PAM <53 (levels 1 or 2)a | −2.6 (1.5) | −5.8 (1.7) | 0.4 (−4.3 to 5.2) |
| PAM ≥53 (levels 3 or 4)a | −4.6 (1.7) | −5.0 (1.8) | 3.3 (−1.2 to 7.7) |
Abbreviations: CI, confidence interval; ES, educational seminar group; HTN, hypertension; PAM, Patient Activation Measure; PL, peer leader group; SBP, systolic blood pressure.
aLevel 1: PAM ≤ 45.2; Level 2: 47.4 ≤ PAM ≤ 52.9; Level 3: 56.4 ≤ PAM ≤ 66.0; Level 4: PAM ≥ 68.5.
