Abstract
                 Background: Diarrhea is the second most important cause of under-five mortality globally in spite of it being easily   preventable and curable. This is largely due to the lack of knowledge among mothers regarding cost-effective  interventions  tackling diarrheal diseases. Objective: To assess the awareness about diarrhea, its prevention, and oral rehydration therapy (ORT) among mothers  of under-five children in urban slums of Bengaluru, Karnataka, India. Materials and Methods: It was a cross-sectional study conducted among 280 mothers of under-five children in  urban  slums of Bengaluru. The data were collected using pretested semi-structured questionnaire administered to eligible   mothers using personal interview method. Descriptive statistics and tests of significance were used in analysis of data  using Epi Info software, version 7. Result: Of 280 mothers interviewed, less than one-fourth (24.3%) knew the correct meaning of diarrhea, with   three-fourths (73.8%) of them not knowing the correct cause of diarrhea. Only 44.3% mothers knew that diarrhea can  be prevented. Majority (88.7%) did not know to look for signs of dehydration. Less than half of the mothers had heard  2 of ORT. By using c -test, preparation of oral rehydration salts (ORS) was found to be associated with the education  of the mother (p = 0.04) proving that knowledge is better among those mothers with formal education. No association  was found between ORS preparation and age of the mother (p = 0.229), religion (p = 0.342), and gender of the child   (p = 0.061). Conclusion: Awareness regarding diarrhea, its prevention, and ORT was found to be lacking among mothers in urban slums.
