OBJECTIVE: To evaluate the prevalence of giardiasis in primary school children in Damascus city and the countryside, and to investigate the possible risk factors for giardiasis infection. METHODS: A cross-sectional study was carried out on school children from 23 primary schools in Damascus, between March and June 2006. Data were collected from 1469 children of both genders from urban and rural regions using structured questionnaires, anthropometric measurements, and laboratory analysis of fecal samples. The parasites were detected using a single-stool sample by direct wet examination under light microscope. RESULTS: Two hundred and six (14%) of 1469 children were infected with Giardia lamblia, while 119 (8.1%) were found infected with other sorts of intestinal parasites. No correlation was found between giardiasis and age, gender, residence in urban or rural areas, availability of piped water or sewage system. In contrast, both mother's (p=0.003) and father's (p=0.018) levels of education, and the number of siblings in-home (p=0.014) were found significant predictors of giardiasis. As for children's nutritional status, 6.6% were found to have significant stunting, 1.8% had underweight, and 4.7% had wasting. Giardiasis, however, was not found a predictor of these conditions. CONCLUSION: The Damascus region could be classified as medium-prevalence area for Giardia infections. Thus, the local administrators need to pay more attention to the prevention of parasitic infections along with improvement in education, environmental, and sanitary conditions.
