ABSTRACT

The relational strategies in group are to improve patient’s BP (blood pressure) control and QoL (quality of life). Methods: Twenty-one hypertensive patients were randomized into two groups: group A (10 patients, age 67 ± 6 years, BMI (body mass index) 28.3 ± 6 kg/m2) was applied relational strategies, with meetings every 15 days 8 meetings; group B (11 patients, age 58 ± 13 years, BMI 28.2 ± 3 kg/m2) with meetings for group orientation every 40 days 3 meetings. The patients were monitored: at baseline (day 15) and at the end of the study (day 120), the BP was measured by auscultatory method and the QoL questionnaire (WHOQOL-BREF) was applied, and was submitted to the examination with ABPM (ambulatory blood pressure monitoring). Results: after 120 days there was a greater (p < 0.05) reduction in SBP (systolic blood pressure) in group A (37.8 ± 25 mmHg) than in group B (18 ± 9 mmHg), but DBP (diastolic blood pressure) decreased similarly in both groups (A, 15 ± 21 vs B, 13 ± 14 mmHg); the HR (heart rate) reduction was larger (p < 0.05) in group A (60.6 ± 8.9 bpm) than in group B (69.7 ± 10.7 bpm). There was a more significant BMI decrease (p < 0.01) in group A (27.8 ± 5 kg/m2) than in group B (28.9 ± 4 kg/m2). The observed correlations between physical domain and nightime DBP (at day 120) in ABPM were r = -0.712 (negative correlation, p = 0.003); between psychological domain and SBP sleep time (at day 120) in ABPM were r = -0.527 (negative correlation, p = 0.044); between environmental domain and daytime Δ HR in ABPM were r = -0.573 (negative correlation, p = 0.007). Conclusion: the health education program conducted through interpersonal relationships within groups provided better control of SBP and greater reduction in BMI.
