Objective Meta-analysis was conducted to study the correlation between hypertension and TCM Constitution, to provide evidence for prevention and treatment of hypertension. Methods By searching the domestic literature database, the relevant literatures of hypertension and TCM constitution were included, the data were extracted and the quality of the included research was evaluated; the heterogeneity test and meta-analysis were performed by RevMan 5.3 software. Moreover, the heterogeneity sources were explored by subgroup analysis, and the publication bias was evaluated by funnel plot. Results A total of 10 articles met the inclusion criteria, involving 4401 patients with hypertension and 7934 patients in the control group. Phlegm-dampness, calmness, Yang-deficiency and dampness-heat all showed obvious heterogeneity. Phlegm-dampness (OR=2.24, 95%CI:1.77~2.83, P<0.001), yin-deficiency (OR=1.28,95%CI:1.13~1.45,P<0.001), Qi-deficiency (OR=1.21,95%CI:1.06~1.37, P=0.005) and blood stasis (OR=1.24, 95%CI:1.06~1.46, P=0.007) were the most common constitutional types in hypertension, while calmness was the most common constitutional type in control group (OR=0.56,95%CI:0.51~0.61, P<0.001). Prior hypertension or not was the main source of heterogeneity, and no obvious publication bias was found from the funnel plot. Conclusion Phlegm dampness, yin deficiency, Qi deficiency and blood stasis are the susceptible constitutions of hypertension and normal constitution is the protection one. However, due to poor quality of research and design flaws, conclusions need to be treated with caution.
