Effects of Caffeine Consumption on Blood Pressure Among Adults at Risk for Increased Intra-ocular Pressure
This study examines the effects of caffeine consumption on blood pressure among adults at risk for increased intraocular pressure attending the Ophthalmic Clinic of a Specialist Teaching Hospital in Nigeria. The study is a retrospective study conducted using questionnaire to obtain information on consumption of caffeinated drinks, coffee, tea and chocolate via the National Health Service semi-quantitative food frequency questionnaire assessment. Subjects who met the criteria and gave informed consent were recruited for blood pressure measurement and the result recorded. Statistical analysis was then carried out and simple descriptive analysis done. The results showed that 388 subjects completed the study with 201 subjects having positive history of caffeine intake. This amounted to a 51.80% prevalence of caffeine consumption among adults attending the Ophthalmic Clinic. Participants positive to caffeine consumption (132.31±16.44/82.41±9.14mmHg) presented significantly higher (p<0.05) mean blood pressure than participants negative to caffeine intake (121.11±9.18/77.75±10.32mmHg). Also, age and gender were observed to significantly influence (p<0.05) systolic blood pressure in participants positive for caffeine consumption as compared to those negative for caffeine intake. The results suggest that caffeine consumption, female gender and advancing age are risk factors for the development of hypertension in adult population at risk of increased intraocular pressure and vice vasa.
