Abstract

Timely detection of prostate cancer (PCA) with prostate-specific antigens (PSA) and digital rectal examinations (DRE) are essential in optimizing incidence, minimizing prevalence, and reducing mortality rates. Given the low levels of participation in cancer screening, this study was conducted to examine the factors men consider when deciding whether to screen for PCA in Nigeria. A cross-sectional, online-based survey of 180 consenting Nigerian men 50 years old and older was carried out. Logistic regression analysis and descriptive statistics were used to analyze the data. Based on the data, there was a moderate positive association between the health belief model constructs and DRE/PSA screening intentions, which were statistically significant (p < 0.05). The results also demonstrated that there were no statistically significant associations between previous screening and age, previous screening and ethnicity, and previous screening and education among men in the sample (all p > 0.05). Of the 180 men surveyed, 29% (n = 53) had been screened for PCA before, while 76% (n = 137) reported no health insurance. Factors significantly associated with screening included income, insurance, and family history of PCA (all p < 0.05). Cancer fatalism, pain, and embarrassment were the most common barriers to screening reported. Focused interventions that help healthcare providers identify barriers quickly could improve screening outcomes. The implications for positive social change from this study include an increase in PCA screening, positive screening intentions, and a decrease in PCA mortality rate among men in Nigeria.
