Résumé
There have been numerous past researches done caffeine use but none of them has been done among doctors on caffeine use and blood pressure. Our aim is to assess whether there is an association between caffeine use and blood pressure among doctors. To compare the blood pressure levels and BMI in doctors who are users or non-users of coffee and other caffeine products. 100 doctors from Gulf Medical University, Gulf Medical College Hospital and Research Center and Umm Al Quwain Hospital participated in the study. Data were collected using a 28 item self-administered questionnaire, and analyzed on PASW-18. Chi square test was done for association and P value of <0.05 was considered significant. The majority of the participants [43%] were in the age group of 38-47 years. 58% were males with 51% Arabs. Coffee consumption was highly prevalent among doctors, with 86% consuming at least on cup per day. 41% drank less than two cups per day while the rest [59%] two cups or more per day. The mean BMI was 25.3 for those who drank less than 2 cups and 27.0 in those who had more than 2 cups; The mean systolic blood pressure [SBP] and the mean diastolic blood pressure [DBP] were 123.71 and 79.1 in the former group and 123.0 and 79.7 in the latter group. The amount of coffee consumed per day did not have any significant effect on the body mass index and blood pressure level of the subjects. The results of this study cannot be generalized as both the predictor and outcome variable was self reported. A larger study should be conducted, with a more objective way of measuring the variables to determine the relation of caffeine on blood pressure
