Title: Education on Caffeine Consumption, to Improve Blood Pressure for Adults ages 19-65, who Consume High Amounts of Caffeine Daily.

Purpose: This project aimed to examine caffeine consumption in the context of its effects on adults' blood pressure, provide education on high caffeine consumption, and evaluate for a reduction in use over four weeks.

Methods: A pretest survey was conducted at a primary care practice to determine caffeine consumption among adults between the ages of 19-65. This session included verbal communication, a 10-minute video, and written educational information. The Caffeine Consumption Questionnaire-Revised was used to obtain information on the participant's caffeine consumption. A post-test survey was conducted at the project site four weeks after the first educational class to assess for a reduction in consumption and improvement in blood pressure.

Results: Thirty participants were recruited, including normotensive and hypertensive individuals. However, twenty-eight participants completed the study. Among the respondents, most were African Americans. The sample consisted of twenty women and eight men with a mean age of 49.1, and age ranged between 33-65. Upon completion of the study four weeks after the initial educational session, there was a 65% reduction of caffeine consumption and a 6%-8% reduction of systolic and diastolic blood pressure.

Conclusion: Overall, the findings suggest that education on high caffeine consumption can reduce the use and improvement of blood pressure.
