The Role of Decaffeinated Coffee in Reducing the Risk of Hypertension: A Systematic Review

Nurheni Sri Palupi, Fatimah

Abstract: Hypertension or increased blood pressure is a degenerative disease with a high prevalence, as well as the biggest cause of premature death in the world. Meanwhile, coffee is a popular and most consumed beverage around the world. Coffee can harm some people with certain health problems including hypertension due to its caffeine content. Decaffeinated coffee is known to be an alternative for people with hypertension with reduced caffeine content up to 97%. However, studies on the role of decaffeinated coffee in reducing the risk of hypertension are still varied indicating that a systematic review is needed. Hence, this study summarizes the evidence related to the role of decaffeinated coffee in reducing the risk of hypertension by using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The inclusion criteria for scientific journals were determined based on Participants, Intervention, Control, and Outcome (PICO). The search using boolean operation resulted in 13 research articles for data extraction. The result revealed that decaffeinated coffee could decrease or did not give any effect on blood pressure or another biological hypertension marker compared to regular coffee.
