High prevalence of elevated blood pressure (prehypertension) and hypertension among undergraduate university students in the UAE: a serious health concern.

Abstract

Hypertension, often referred to as a "silent killer," due to its lack of obvious symptoms but can lead to devastating complications such as cardiovascular disease and stroke, particularly when left unmanaged. This highlights the importance of early screening of elevated blood pressure. The aim of this study is to determine the prevalence of elevated blood pressure (prehypertension) and hypertension among undergraduate university students, along with the associated risk factors. We recruited 344 randomly selected undergraduate students for a cross-sectional study. Blood pressure (BP) measurements were taken following best practice guidelines. In addition, body mass index (BMI) was measured, while other risk factors were collected through a questionnaire. Out of all participants, 36% exhibited elevated blood pressure, with the following breakdown: 15% (n = 51) had prehypertension, 18% (n = 62) had stage 1 hypertension, and 3% (n = 10) had stage 2 hypertension. The prevalence of hypertension and prehypertension was significantly higher among male students (52.7 and 100%, respectively) compared to female students (47.3, and 0% respectively). Significant correlations were found between blood pressure, BMI, and physical activity levels (P ≤ 0.001 and P ≤ 0.011, respectively). Our findings reveal a concerning prevalence of prehypertension and, to a greater extent, hypertension among undergraduate university students. Elevated blood pressure levels were strongly correlated with male gender, BMI, and physical activity levels. These results warrant further large-scale investigation and underscore the urgent need to raise awareness about this significant health risk in the younger population.
