Abstract
Introduction: Schistosomiasis, or bilharzia, is a parasitic disease caused by flatworms of the genus Schistosoma. Among the most common species affecting humans, Schistosoma mansoni is responsible for the intestinal form, which is widespread in sub-Saharan Africa.The objective of this study was to determine the prevalence and identify factors associated with schistosomiasis mansoni in the rural health zone of Oicha.
Material and Methods: This was an analytical cross-sectional study conducted in the rural health zone of Oicha for 10 months, from March 10 to December 31, 2023, on 400 respondents.
Results: The study found a prevalence of 57.5% with factors associated with schistosomiasis mansoni: sociodemographic, Agri-ecological, sociocultural, environmental, political, socioeconomic and nutritional factors, male gender with P=0.002; OR=3.65; CI= [1.04-5.72], single with P=0.004; OR=3.81; CI= [1.12-5.43]; no education level P=0.000; OR=5.53; CI= [1.07-6.43], the fact that residents play in rainwater with P=0.006; OR=3.43; CI= [1.54-5.02], to irrigate the field P=0.033; OR=2.55; IC= [0.97-3.42], doing oil pressing and swimming in dirty waters P=0.015; OR=1.85; IC= [0.59-2.92], changing residence P=0.000; OR=2.83; IC= [0.86-3.54], washing in the river P=0.000; OR=2.87; IC= [0.79-3.50]; defecating in holes at 60.9% with P=0.000; OR= 3.63; CI= [1.12-4.26], short distance from field P=0.008; OR=4.43; CI [1.54-7.01], drinking water shortages P=0.004; OR=3.68; CI= [1.43-4.69], washing in the river P=0.004; OR=2.76; CI= [0.65-3.15]; washing rolling stock P=0.012; OR=3.85; CI= [1?43-4.03], digging sand in rivers P=0.044; OR=4.37; CI= [1.28-5.79], consuming infested crabs P=0.001; OR=2.64; CI= [0.54-4.06].
Conclusion: The prevalence of the disease was 57.5%, children are more affected than adults with factors associated with schistosomiasis mansoni: sociodemographic, agri-ecological, sociocultural, environmental, political, socioeconomic and nutritional factors. Univariate, multivariate and logistic regression analyses were performed using SPSS 27.
Keywords: Prevalence, associated factors, schistosomiasis mansoni, Oicha rural health zone.
