e22508 Background: Abuja, Nigeria’s annual World Cancer Day Walk (WCDW) is a tool for promoting public awareness of cancer risk factors, preventative lifestyle strategies, and the importance of early screening as critical elements of prevention and control. The day includes physical activities (walk, race, ride, skate, cycle, marathon), as well as health education and free breast cancer, cervical, and prostate screenings. The effectiveness of the event to attract the most vulnerable Nigerian populations has not been studied. Aim: To determine the social-demographic characteristics of participants and evaluate the impact of outreach campaigns. Methods: Approximately 2,000 Nigerians attended Abuja WCDW on February 1, 2020. A similar number attended Abuja WCDW on February 5, 2022. Trained research assistants recruited participants to complete a one-sheet questionnaire that assessed basic demographic, social, and lifestyle information. Participants were given informed consent. In 2020, 237 (11%) participants, aged 18-68 years voluntarily completed survey (ClinicalTrials #NCT04248881). In 2022, 111 (6%), aged 17-74 years voluntarily completed survey (ClinicalTrials #NCT05239325). Note: In 2021, Abuja WCDW was canceled due to COVID. Results: In 2020, the mean age for participants was 28; SD 7.71. Sixty-eight percent were women. Eighty-seven percent had at least an undergraduate education. Of the 237 participants, 65% reported that they attended to obtain free cancer screening. More than 50% reported they had no health insurance. Of those insured, more had National Health Insurance Scheme (NHIS) than private insurance. The average body mass index (BMI) was between 24-28; BMI was highest among the mid-20 age group. Lifestyle data revealed more men than women were concerned with their health; those with health worries were more likely to have had cancer screening at the event. The 2022 WCDW data were being analyzed at the time of abstract submission; findings will be presented at the meeting. Analysis: Data from 2020 revealed participants are predominately associated with a lower risk of developing cancer. They have higher levels of knowledge about cancer and lifestyle/health-related behaviors beneficial for early detection and prevention. WCDW is a great avenue for cancer awareness/lifestyle prevention interventions yet there is an urgent need to evaluate efficacy of current outreach to target underserved members of Nigerian population: those with lower levels of education, unemployed, lower income, and without insurance. Conclusions: Attendees in 2020 are younger people of higher socioeconomic status with lifestyle practices that could reduce cancer risk. If our 2022 data are similar, we must elaborate better strategies to reach populations at greater risk and encourage them to attend future events to have more impactful lifestyle/prevention outcomes.
