Purpose: This study looked at the impact of a community-based public health campaign on hypertension and diabetes mellitus awareness and prevention, as well as student experiential learning in a campaign conducted by pharmacy students. Design/methodology/approach: A convenience sampling cross-sectional pre-post survey was done to assess disease awareness and knowledge among those who attended the health campaign. The data analysis includes a total of 230 participants with complete data. After the campaign, the pharmacy students used self-assessment to reflect their learning experience. Findings: Most participants were unaware of their blood pressure and blood glucose readings, but they reported improved awareness of diseases and prevention of hypertension and diabetes after the health campaign. Although most participants correctly identified the common signs and symptoms of hypertension, few could associate it with overweight. Most participants were unaware of the 5 g per day salt intake limit for controlling hypertension before the campaign. Most participants were less aware that diabetes is associated with impaired vision, peripheral neuropathy, renal and heart diseases. Students expressed increased confidence in leadership, teamwork and communication abilities after the campaign based on self-assessment. Practical implications: A health campaign enhances the disease knowledge of the general public. It has been suggested that experiential learning be encouraged in the pharmacy curriculum. Originality/value: This study adds to the knowledge on the roles of community-based health campaigns and the value of pharmacy students' involvement in experiential learning.
