This study investigated the relationship between peer group influence, family standard of living, and prostitution tendencies among university undergraduates in southeast Nigeria. The study utilized a survey research design and questionnaire to collect data from 1,983 undergraduates across five universities. The findings showed a positive correlation between peer group influence and prostitution tendencies. Additionally, undergraduates from families with a low standard of living exhibited higher tendencies toward prostitution compared to those from families with a high standard of living. The study recommended introducing sex education in university curriculums to address this issue.
