Prevalence of intestinal parasitic infections and its relationship with socio–demographics and hygienic habits among male primary schoolchildren in Al–Ahsa, Saudi Arabia

Abstract

Objective: To investigate the prevalence of different intestinal parasitic infection among male primary schoolchildren in Al-Ahsa, Saudi Arabia, and to explore the possible relative socioeconomic, environmental and behavioural sanitary correlates. Methods: A cross-sectional descriptive study was performed. A total of 1289 male students aged from 7 to 12 years were selected randomly from 20 urban and 12 rural primary schools by multistage sampling method. Data collection was carried out by self administered questionnaire form to the parents/guardians of students and included inquires about socio-demographics, environmental conditions, and behavioural sanitary habits. Stool analysis was carried out to examine the presence of intestinal parasitic infections. Results: Overall prevalence of parasitic infections was 27.2%, more among rural students. Frequently encountered infections included Entamoeba histolytica/dispar (8.2%), Giardia lamblia (6.5%), Entamoeba coli (4.0%) and Enterobius vermicularis (1.6%). Logistic regression revealed that lower maternal educational level and occupational status, low family income, big family size, poor personal hygienic practices and positive history of previous intestinal infections among family members increased the likelihood of infections. Conclusions: Although of low magnitude, intestinal parasitic infections still represent a public health concern among male schoolchildren in Al-Ahsa region. Socio-demographic and poor personal hygienic habits are the main predictors for these infections.
