Our objective is to evaluate the effects of qigong on blood pressure, health status and hormone levels for pre- or mild hypertension.
Forty subjects with pre- or mild hypertension were randomized to either the qigong exercise group or the non-treated group. Participants in the qigong group conducted qigong exercises 5 times per week for 8 weeks, and participants in the non-treated group maintained their current lifestyle, including diet and exercise. The primary endpoint was a change in patient blood pressure. Secondary endpoints were patient health status and changes in hormone levels.
Of the 40 participants that were randomized, 35 completed the study. Systolic and diastolic blood pressure were significantly decreased after qigong treatment compare to baseline, in only qigong group after 4 weeks (p = .0006 in sbp, p < .0001 in dbp). The significant change of bp in qigong group lasted to follow up 4 weeks (p = .0083 in sbp, p < .0001 in dbp). In non-treated group, there was significant difference in only sbp (p < .002 in 2 weeks, and p = .0009 in 4 weeks). The change of blood pressure between qigong and non-treated group was significant in 4 weeks (p = 0.006 in sbp, p = 0.0003 in dbp), not in 2 weeks. (p = 0.87 in sbp, p = 0.91 in dbp) in the change of norepinephrine, cortisol, renin, angiotensin, hdl, ldl, there was no significant difference between qigong and non-treated groups.
The score of mymop2 did not show significant decrease in qigong group than non-treated group (p = .17 in 4 weeks). Among subscale of mymop2, only wellbeing category was significant between 2 groups (p = 0.033 in 2 weeks, p = 0.032 in 4 weeks), not in symptom or activity categories.
Qigong appears safe and positive effect on blood pressure and health status in pre and mild hypertension patients. Further long-term studies with a larger number of subjects are warranted.
