This study evaluated the extent to which married Idoma (Benue State) and Igala people (Kogi State) in North-Central Nigeria were exposed to the 2017 National Family Planning Communication Campaigns. The study also examined their level of knowledge, the extent to which they adopted the campaign messages, and how Alekwu/Ibegwu and other socio-cultural factors influenced their level of adoption of the campaign messages. The study adopted a quantitative (questionnaire survey) research method. The data were subjected to a descriptive analysis, correlation, ANOVA, Pearson Product Movement Correlation (PPMC), and Binary Logistics Regression. The findings showed that the majority of the people were exposed to information on condoms, implants, and Intrauterine Contraceptive Devices (IUCDs) (Cuppar T) in the course of the campaign; however, most of them were not exposed to information on Oral Pills, Vasectomies, Tubal ligation and Injections. Findings also revealed that knowledge of modern family planning in the study areas (51.2%) was below the 85.8% national family planning knowledge threshold and far below the expected 95% target of the 2017–2020 family planning communication campaign goal. Findings equally showed poor adoption of the campaign messages due to their cultural beliefs. The study concluded that family planning was often accepted among people whose ways of life have been significantly altered in favour of the idea.
