Objective To systematically review the association between insomnia and the risk of hypertension. Methods The EMbase, PubMed, The Cochrane Library, VIP, WanFang Data and CNKI databases were electronically searched to collect cohort studies on the association between insomnia and hypertension from inception to October 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 13.0 software. Results A total of 20 cohort studies involving 607 409 participants were included. The results of meta-analysis showed that insomnia increased the risk of hypertension (RR=1.24, 95%CI 1.15 to 1.34, P<0.000 1). Subgroup analysis showed that insomnia increased the risk of hypertension in North American, European and Oceanian population, but not in Asian population. The difficulty falling asleep, difficulty maintaining sleep and early awakening all increased the risk of hypertension. Conclusion Current evidence suggests that insomnia increases the risk of hypertension.
