This study evaluated the effectiveness of radio messaging in promoting prostate health awareness and preventive behaviours among men in North-Central Nigeria. Anchored on the health believe model, the study adopted a mixed-methods approach involving a survey and in-depth interview. The survey targeted men aged 40–70 years, with 428 respondents sampled and 424 valid responses analysed. Fifteen key informants were interviewed. Data were analysed using frequencies, percentages, thematic analysis and Pearson correlation. Findings revealed that 70% of respondents had been exposed to prostate health messages through radio, while 69.6% listened to such messages daily or several times weekly. About 78% reported improved understanding of prostate cancer, while 55.9% perceived the disease as a serious health condition. Preventive responses included lifestyle modification (32.1%), screening (26.4%), and seeking medical advice. However, poor signal, irregular electricity supply, language barriers, limited radio access, and urban-rural disparities constrained effectiveness. The researchers conclude that radio remains an effective channel for prostate health communication. Sustained impact requires culturally relevant content, local-language broadcasting, interactive formats, and stronger collaboration among media organisations, health institutions, and community stakeholder. These measures can strengthen reach, comprehension, engagement, and adoption of preventive behaviours among men.
