Environmental Sanitation and Its Correlation With Intestinal Worm Infection In Elementary School Students In West Amanuban District, East Nusa Tenggara, Indonesia

Background: Intestinal parasitic infections are still major public health problems. ntestinal parasitic infections, mainly Ascariasis, Trichiuriasis, and hookworm, are common clinical disorders in man, with resultant impairments in physical, intellectual, and cognitive development. The greater proportion of infections is associated with poor water, sanitation, and hygiene (WASH). This study aimed to examine the correlation between environmental sanitation and intestinal worm infection. Subjects and Method: This was a cross-sectional study conducted at elementary school students in West Amanuban, East Nusa Tenggara, Indonesia. A sample of 160 elementary school students was selected by simple random sampling. The dependent variable was intestinal worm infection. The independent variables were poor latrine, type of latrine, poor drinking water sources, poor trash bins, poor sewerage, the presence of animals, and the presence of cages. The data were collected by questionnaire and analyzed by Chi square. Results: The risk of intestinal worm infection in elementary school students increased with poor latrine (OR= 6.41; 95% CI= 2.49 to 16.53; p<0.001), type of latrine (OR= 23.93; 95% CI= 5.42 to 105.71; p<0.001), poor drinking water sources (OR= 3.94; 95%CI= 1.78 to 8.71; p=0.001), poor trash bins (OR= 8.53; 95% CI= 3.93 to 18.52; p<0.001), and poor sewerage (OR= 5.25; 95% CI= 2.42 to 11.42; p
