Prostate cancer (PCa) is a public health concern among Black men, however physical activity and good dietary pattern could be a key component for preventing or slowing the progression and improving prognosis of the disease. In addition, the knowledge of PCa could induce behavioral change; conversely, knowledge may not necessarily lead to change in physical activity and dietary pattern. The purpose of this study was to assess the association of PCa screening behavior and knowledge with exercise, and dietary pattern among Blacks using the Prostate Cancer Transatlantic Consortium (CaPTC) Cohort study data. A retrospective cross-sectional study was carried out among 500 participants. Information on knowledge of PCa and participants screening behaviors was obtained in three countries (Nigeria, Cameroon, and USA). Participants’ dietary pattern was evaluated using food variety score and physical activity was evaluated for those involved in moderate intense exercise. Categorical variables were presented with frequency and percentages and analyzed using chi square while continuous variables were presented using mean (standard deviation). Analysis of variance and correlation were respectively used to determine variations and associations between variables. Data were analyzed using SPSS version 22. Results showed that 78.26% and 87.37% had never screened for PCa through prostate specific antigen (PSA) and digital rectal examination (DRE), respectively. There was significant association between country and PCa screening (p=0.001 and 0.001) for PSA and DRE, respectively. Moreover, 65.2%, 19.8%, and 15% had poor, fair, and good knowledge on PCa respectively, the study showed no association between country and PCa knowledge score (p=0.151). More than half (66.7%) of the men were not engaged in moderate intense exercise and there was significant association between exercise pattern and countries (p&lt;0.001). In addition, about 45.5% of the participants had poor dietary pattern. There was significant difference in the food variety score between the countries (p=0.001) with USA having the highest mean score (29.76±12.52). There was no association found between PSA and DRE and participants’ engagement in physical activities (p value =0.975 and 0.886, respectively), similar trend was observed with dietary pattern as PSA and DRE p-values were respectively 0.881 and 0.838. Participants’ PCa knowledge was not associated with physical activities (p=0.337) but associated with dietary pattern (p=0.006). The study showed that knowledge and screening of PCa were not associated with physical activity while dietary pattern was associated with knowledge and country only.
