INTRODUCTION Prostate Cancer (CaP) disproportionately overburden men of African ancestry, especially Black men (BM). Unfortunately, few CaP studies have focused on the heterogeneity of BM within the US as well as the source population of US BM in Africa. The Prostate Cancer Transatlantic Consortium (CaPTC) team has documented differences in CaP-related behavioral factors, health-seeking behaviors and experiences between US-born and foreign-born Blacks since 2005. The CaPTC familial cohort study was developed to understand the genetic, environmental and behavioral etiology of CaP in West African men (WAm). This presentation focuses on the impact of migration on prostate health factors among WAm. Methodology The CaPTC cohort study in a longitudinal study and is still ongoing. The inclusion criteria are WAm, age 35-70 years, and residing in the US, Nigeria and Cameroon. Participants were recruited in diverse community settings. Data were collected from participants who provided informed consent using the CaPTC-AC3 Global Prostate Cancer Measure. The variables included in this presentation are general demographics, cultural beliefs and values, health beliefs, sun exposure, vitamins, body shape, and baldness. In addition, self-reported measures of prostate health were assessed. In addition to descriptive analyses, ANOVA/comparative analyses was used to examine differences among WAm in the US, Nigeria and Cameroon. Results The scales employed for the construct were highly reliable (alpha over 0.80). By December 2018, the sample size was 704 WAm with 81% recruited in Nigeria, 10% recruited in Cameroon and 9% recruited in the US. The average age was 48. Most of the WAm live in Nigeria, are married, middle-income level, Christian by faith and had never been screened for CaP. There was statistically significant differences among the WAm based on their country of residence with respect to CaP history (Nigeria), skin color (darker skin color in Cameroun), vitamin use (mostly by WAm in US), and pattern of baldness at age 30 (WAm in Nigeria). In addition, there was statistically significantly differences relative to cultural beliefs and values (cancer fatalism, religiosity, temporal orientation) and health beliefs (perceived barrier, perceived benefit). Cancer fatalism was lowest among WAm in US; religiosity was highest among WAm in Nigeria; WAm in the US were more future-oriented and WAm in Cameroun more present-oriented; perceived barrier was lowest for WAm in US; and perceived benefit highest for WAm in the US. Conclusion The increasing number of the African immigrant group in the US underscores the need to study within group difference among Blacks in the US. Unfortunately, this group is understudied and may offer a novel approach to fully understand cancer disparities in Blacks. Studying the impact of migration on CaP burden in this population provides several advantages, including identification of CaP risk factors. Our study confirms that migration impacts prostate health factors among WAm.
