Abstract
Hypertension is a major global public health concern, yet awareness among college students remains inadequate. This study evaluated the effectiveness of a structured educational intervention on hypertension knowledge among college students in Bangladesh using a pre-post interventional design. A total of 384 students (236 males, 148 females) aged 18-23 years participated, with 175 assigned to the intervention group and 209 to the non-intervention group. Data were collected using a validated semi-structured, pre-tested questionnaire. The intervention was delivered in three sessions at 15-day intervals. Paired t-test and Fisher’s exact test were applied, with p < 0.05 considered significant. The intervention group demonstrated significant improvements across all knowledge domains (t = 44.42, 48.31, 36.96, 37.39, and 24.66; p < 0.001), and knowledge levels increased significantly compared with those in the non-intervention group (p < 0.001). No significant change was observed in the non-intervention group (p = 0.825). The findings indicate that structured educational intervention programs are highly effective in improving hypertension awareness among college students.
