Abstract
Introduction : Intestinal helminthiasis remains a major public health issue in tropical countries, particularly affecting children in Madagascar. This study aimed to determine the prevalence of intestinal helminthiasis among children aged 5–15 years in the rural com
mune of Ampefy, and to explore associated sociodemographic, clinical, and environmental
factors. Materials and Methods : A cross-sectional study was conducted from August to September 2022, including 107 children after parental consent. Data were collected using structured questionnaires and parasitological stool examinations. Results : The overall prevalence of intestinal helminthiasis was 40.2% (43/107). Schistosoma mansoni was most frequent (24.3%), followed by Ascaris lumbricoides (17.76%) and Trichuris trichiura (3.74%). Polyparasitism occurred in 6.53%, mainly Ascaris-Schistosoma co-infections. Boys were more affected than girls (58%, p=0.048), with the highest prevalence among 5-year-olds (81.82%, p=0.030). Infection prevalence decreased with higher education levels (p=0.035). Significant risk factors included absence of latrines (p=0.043), use of non-potable water (p=0.002), and abdominal symptoms (p=0.044). Clinically, 72.09% of infected children reported abdominal symptoms, and 17.65% exhibited stunting. Conclusion : Intestinal helminthiasis is endemic in Ampefy, with a high burden among young children. Interventions should focus on improving sanitation, access to clean water, health education, and mass deworming. Strengthening national strategies is essential to reduce the impact of helminthiasis on child health and local socio-economic development.
