Objectives To assess the effect of slow breath training program on the blood pressure (BP) in
hypertensive patient
Methods A randomized controlled trial was study between December 2015 and February
2016 in Bangwau Health Promoting Hospitals, Bangpakong District, Chacheongsao Province. 60
hypertensive patients were randomly allocated to the intervention group (n=30) of slow breath
training program and usual medical care or to a control group (n=30) of only usual medical
care. The primary analysis was comparing BP change from baseline to final visit both groups
at 8 weeks’ follow-up.
Results 56 participants were analyzed, 4 participants in intervention group were excluded
due to 2 participants discontinued breath training program and the others loss of follow-up
however no adverse events. The study found that intervention group was improvements in
systolic BP (SBP) -7.5 mmHg (95% confidence interval(CI), -11.5 to -3.4 mmHg), diastolic BP (DBP)
-4.4 mmHg (95% CI, -7.1 to -1.6 mmHg), and mean arterial pressure (MAP) -5.4 mmHg (95% CI,
-8.1 to -2.7mmHg). The control group showed increase in SBP 5.5 mmHg (95% CI,-0.95 to 10.1
mmHg) but DBP and MAP was not significant BP change from baseline. The comparing between
intervention and control group showed SBP change (-7.5 mmHg Vs 5.5 mmHg, respectively;
difference 13 mmHg 95% CI, 6.94 to 19.05; P<0.01) and MAP change (-5.4 mmHg Vs 0.9 mmHg,
respectively; difference 6.3 mmHg 95% CI, 2.47 to 10.03; P<0.01), unfortunately DBP was not
significant difference.
Conclusion Over an 8-weeks treatment period, slow breath training program is effective in
reducing blood pressure in hypertensive patients.
