Introduction: Hypertension is a major cause of death in the world, it is urgent to intervene in their risk factors for prevention and treatment. The associationbetween coffee intake and hypertension has made health professionals advise against him.
Objective: To evaluate the effect of coffee consumption in systolic and diastolic blood pressure in adults and elderly with hypertension.
Methods: The systematic review of the literature with meta-analysis following the principles proposed by the Cochrane Handbook was performed. The critical analysis, extraction and synthesis ofdata were carried out by two investigators separately and meta-analyses were performed using RevMan 5.3.5.
Results: Three Randomized Clinical Trials (RCT) and twocohort studies covering 264 and 1919 individuals were included respectively. The results of meta-analysis, which included the RCT indicates that the ingestion of coffee with reduced Hydroxyhydroquinone (HHQ) has beneficial effect on systolic blood pressure (MD= -2.60; 95% Cl=-4.81, -0.39; p=0.02) and diastolicblood pressure (MD= -1.30; 95% Cl=-1.67, -0.93; p<0.01). Other studies have shown that the in adult population with hypertension, coffee consumption doesnot interfere with blood pressure. However consumption of more than three cups of coffee a day is associated with the risk of hypertension. In elderlysubjects with hypertension, consumption of more than three cups of coffee increases blood pressure and the possibility of uncontrolled blood pressure.
Conclusion: Consumption of more than three cups of coffee a day is not recommended in people with hypertension. Coffee intake with reduced HHQ is advised.
