ABSTRACT
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 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.
ABSTRACT
OBJECTIVE: The Covid-19 pandemic is the major global health crisis of our time. The purpose of this study is to estimate the seroprevalence of IgG against SARS-CoV-2 among workers in the University Hospi-tal of Guadeloupe and to assess this seroprevalence in asymptomatic personnel as well as the proportion of asymptomatic agents among seropositive agents. SETTING AND METHODS: We carried out a seroprevalence study in the staff of the University Hospital of Guadeloupe. The presence of IgG anti SARS-CoV-2 was determined by a micro-particulate immunolo-gical assay using the chemiluminescence technique (CMIA, Architect i2000SR, Abbott). Data on the previous presence of symptoms sugge-stive of COVID-19, were identified using a standardized questionnaire. Statistical analyses were performed using Epi Info® software. RESULTS: From 07/05/2020 to 28/10/2020, 892 serologies were performed, 45 of which were positive for SARS-CoV-2 : a prevalence of 5.0% [95% CI: 3.6% - 6.5%]. Seroprevalence was 1.5% [95% CI: 0.6% - 2.3%] among agents who reported being asymptomatic. Among seropositive individuals, 24.4% [95% CI:12% - 36%] was totally asymptomatic. CONCLUSION: Our results highlight the importance of continuing seroprevalence studies for SARS-CoV-2 in hospital staff, which can provide important information on the level of exposure in healthcare workers and asymptomatic transmission of SARS-CoV-2 in clinical set-tings.
