Abstract
BACKGROUND: Soil-transmitted helminth (STH) infection control remains a priority in endemic regions where local epidemiological data are needed for sustainable control strategies, particularly regarding population knowledge, attitudes, and practices (KAP). Our work assessed KAP toward STH infection and associated factors among residents of Bata district, Equatorial Guinea. METHODS: A community-based cross-sectional study was conducted among 14 randomly selected communities in the Bata district. Eligible participants were interviewed face-to-face using a standardized questionnaire. Participants aged under 18 years were interviewed in the presence of their parents or legal guardians. For participants aged less than ten, a simplified version of the main questionnaire was developed focusing on children's practices toward STH and was administered to their parents or legal guardians. RESULTS: A total of 399 participants were included in the present analysis. Among them, 58% responded to the main questionnaire. The mean (± SD) age of participants aged 10 and over was 37.5 (± 22.2) years, and 60% of them were females, while the mean (± SD) age of those aged less than ten was 5.0 (± 2.5) years. The respondents' overall knowledge, attitudes, and practices to STH were rated as bad (33%), very good (77%), and good (55%), respectively. Knowledge was significantly associated with education level (p = 0.04) with the knowledge level lower for participants with no formal education than for those with secondary/university education (β = -0.56, 95% CI: -1.00 - -0.12, p = 0.01); Appropriate attitudes level was significantly associated with occupation (p = 0.02) and education levels (p = 0.049) with the appropriate attitude level lower for students than for farmers/fishers (β = -1.24, 95% CI: -2.17--0.32, p = 0.01) and for primary-level participants than for those with secondary/university education (β = -0.68, 95% CI: -1.23--0.13, p = 0.02); while appropriate practice level were significantly associated with age (p = 0.01), occupation (p = 0.01), and education (p = 0.02), with the appropriate practices level increasing with age (β = 0.03, 95% CI: 0.005 - 0.05, p = 0.01) and lower in participants with no formal education than in those with secondary/university education (β = -1.19, -2.05 - -0.32, p = 0.007). CONCLUSION: The present study revealed a lack of knowledge about STH in the study population, particularly regarding disease causes and transmission ways, highlighting the need for the implementation of integrated health education strategies, both at the community and school levels.
