RESUMO
The drinking of coffee, a commonly used beverage, was a subject of many studies, mainly regarded to coffee influence on cardiovascular system. However, only one study indicates that coffee drinking in male adults may lead to decrease in serum uric acid level. Hyperuricaemia is a risk factor of many diseases. The aim of this study was to examine the influence of coffee drinking on serum uric acid concentration. 1955 working persons aged from 18 to 65 years were included into research. There were 571 women among them. We determined energy expenditure during professional work, blood pressure, body mass index, and measured serum levels of uric acid, glucose and creatinine. The amount of coffee and ethanol consumption was evaluated on the ground of an interview. It was showed that persons drinking coffee have lower serum uric acid concentration than non-drinkers, especially among women, who drank more coffee then men. Uricaemia was correlated negatively with number of cups of coffee consumed and positively with body mass index, ethanol consumption and diastolic blood pressure. The author conclude that: 1) among women drinking on an average 10 cups of coffee per week appeared a decrease in serum uric acid concentration and a lower risk of development of hyperuricaemia, 2) elevated serum uric acid concentration is accompanied by elevated blood pressure and increased body mass index.
