Abstract

Research Statement/ResearchQuestion This study assesses the health literacy of high school students’ before and after an educational presentation about hypertension, a health condition more prevalent in underserved communities.

Background Low health literacy is associated with worse health outcomes, particularly within underserved communities. Improving health literacy among high school students can empower them to take action to improve health and well-being within their communities.

Methods In spring 2023, medical students from IUSM visited four high schools to educate students on health literacy and hypertension. Participants completed a 15-item test prior to and immediately following the presentation. Demographic data (grade level, race, ethnicity, and gender) was collected. Data was collected anonymously, using assigned codes to match pre- and post-tests. Data was analyzed using paired samples t-tests and ANOVA.

Results A total of 104 high school students completed pre- and post-tests. There was a significant improvement in quiz scores from pre- (7.95±1.74) to post-test (9.41±2.01; p<.001). One-way ANOVA found significant differences in pre- and post-test performance based on race, with Black students scoring lower than White students on both pre-test (7.28±1.28 vs. 8.31±1.70; p<.05) and post-test (8.55±2.21 vs. 9.85±1.76; p<.05). There was also a significant interaction between students’ gender and their pre- and post-test scores with female students showing greater improvements in test scores than male students.

Limitations This study was conducted in a single school district in a small midwestern city and may not be generalizable to larger urban or rural populations. The presentation was given during a science class and may have been biased by students’ prior knowledge. Differences among presenters may also impact students’ comprehension.

Conclusion High school students’ health literacy improved after an educational presentation on hypertension. This study revealed racial disparities in health literacy, highlighting the need for more health education in schools that have more students from underserved racial and ethnic groups.
