The objective of the study was to investigate associations between coffee consumption and the occurrence of metabolic syndrome (MetS) and its components in individuals with a normal BMI, as well in those who are overweight and obese. The analysis was based on the data of 10,367 participants. The studies included a questionnaire interview, anthropometric measurements, blood pressure measurements and analyses of collected fasting-blood samples. In the overweight and obese participants, lower coffee consumption, compared with higher consumption was correlated with a significantly higher risk of abdominal obesity, hypertension, an abnormal glucose concentration, HDL cholesterol, triglycerides and MetS (p < .05). In the participants with a normal BMI, lower coffee consumption was related to the abdominal obesity, HDL cholesterol and MetS (p < .05). Individuals with a normal BMI may react slightly differently to nutritional factors modifying metabolism such as coffee, compared with those with excessive body mass.
