The effect of health coaching on blood pressure control and disease self-management among patients in rural area in China: a randomized controlled trial

The self-management education for patients with hypertension has not been widely provided in rural areas of China. Our study aimed to examine the effect of health coaching intervention on controlling BP and improving self-management skills among rural resident of <= 6 month-history of hypertension. A total of 102 participants were enrolled in the RCT. The control group received usual health guidance and follow-up management; the experimental group received health coaching and follow up management. The primary outcomes were the difference in changes of BP and mean self-management scores. The secondary outcomes included waist circumference, body mass index (BMI), and medication literacy. Participants in the experimental group showed a significantly greater improvement with respect to systolic BP and diastolic BP respectively (133.85 +/- 4.74 mmHg vs 127.96 +/- 5.42 mmHg;80.94 +/- 5.52 mmHg vs 77.37 +/- 4.44 mmHg, P < 0.05) and BMI (24.66 +/- 2.19 kg/m(2) vs 23.44 +/- 2.05 kg/m(2), P < 0.05) compared with the control group. A significant difference was also observed between the experimental and control groups in terms of self-management and medication literacy at both 3 and 6 months (P < 0.05). However, there was no significant difference in changes of waist circumferences between the two groups (22.6% vs 38.8%). In conclusion, for patients with diagnosed with hypertension within the last 6 months, health coaching maybe is an effective approach to control blood pressure and improve medication literacy and self-management skills.
