Efeito do consumo de café na pressão arterial de adultos: revisão de literatura

Abstract

INTRODUCTION: Blood pressure is an important parameter for cardiovascular assessment and may be influenced by dietary habits, including the consumption of stimulant beverages such as coffee. Although coffee is widely consumed by adults, its effects on blood pressure levels remain divergent in the literature and may vary according to the amount consumed, preparation method, caffeine content, previous consumption habits and individual characteristics. OBJECTIVE: To analyze, through an integrative review, the effects of coffee consumption as a beverage on blood pressure in adults. METHODOLOGY: The PubMed, Web of Science and Scopus databases were searched, considering studies published between 2015 and 2025, in Portuguese or English, conducted with adults. Clinical trials, randomized, controlled, crossover studies and clinical intervention investigations that evaluated coffee consumption and its effects on blood pressure or related cardiovascular parameters were included. After applying the eligibility criteria, seven studies composed the final sample. RESULTS AND DISCUSSION: The studies indicated that acute coffee consumption may cause a temporary increase in blood pressure in some individuals, especially in situations of greater sensitivity to the beverage or non-habitual consumption. However, among habitual consumers, healthy adults or treated hypertensive individuals, the observed effects were less consistent and did not always reach statistical significance. CONCLUSION: Coffee consumption has variable effects on blood pressure in adults, depending on dose, preparation method, caffeine content, frequency of consumption and individual characteristics. Therefore, guidance regarding coffee intake should be individualized, especially for people with hypertension, greater sensitivity to caffeine or increased cardiovascular risk.
