In Nigeria, adolescents in urban slums are increasingly at risk of adverse sexual and reproductive health (SRH) outcomes. However, little is known about how individual factors predict parent-adolescent communication on SRH issues in a resource-poor urban setting in Ibadan. Thus, this study investigated individual factors associated with parent-adolescent communication on SRH issues in urban slums of Ibadan, southwest, Nigeria. This study is part of a larger project that explores the socio-ecological factors influencing parent-adolescent communication on SRH issues in selected slums in Ibadan, Nigeria. Within this broader framework, this paper relies on the quantitative data obtained in 10 selected slums. Interviewer-administered structured questionnaire [scripted on open data kits (ODK)] was utilized to collect data from a sample of 796 parent-adolescent dyads. Six SRH topics were investigated to describe the issues discussed. Analytical techniques utilized include; frequency counts, chi-square, and multinomial logistic regression. Parent-adolescent communication regarding SRH issues is not uncommon in urban slums of Ibadan but characterized by indirect communication, threat and warning. Parents and adolescents' age, gender, marital/relationship status, educational attainments and religion played influential role in parent-adolescent communication regarding SRH issues. These factors were identified to be significantly associated with the pattern of parent-adolescent discussion of SRH issues. Age-specific SRH education should be available to adolescents and parents need to be educated on appropriate SRH information and the best way to engage their adolescents on SRH issues.
