Introduction: Diarrhea is the second major cause of death in toddlers in developing countries, including Indonesia. The study aims to determine the relationship between knowledge, attitudes, and behavior of mothers regarding prevention and treatment of diarrhea with the number of toddlers taken to the health facility. Methods: A cross-sectional study was involving 120 mothers who have a child with a history of diarrhea and were recruited using a simple random sampling method. Data were collected using demographic and diarrhea-related questionnaires. Fisher-Exact test was used to analyze data in univariate and bivariate with p-value ≤ 0,05 as the level of significance. Results: Most of the mother’s knowledge, attitudes, and behavior regarding diarrhea were considered fairly good, with the percentage reaching 70,8%; 66,7%; 70,8%, respectively. However, knowledge, attitude, and behavior regarding giving ORS were low. There was a significant relationship between the attitude and behavior of the respondents with the number of diarrhea toddlers taken to health facilities (p = 0,010; p = 0,000), but there was no significant relation with the respondents’ knowledge (p = 0,065). Conclusions: The attitude and behavior of mothers regarding diarrhea significantly affect the number of diarrhea toddlers taken to the health facility. Although the overall knowledge, attitude, and behavior of the mother were considered fairly good, but the knowledge, attitude, and behavior regarding giving ORS were low.

Anemia can be caused by a decrease in hemoglobin (Hb) levels, chronic disease, severe bleeding, nutritional deficiency, and infectious diseases. Iron deficiency is the most common cause of anemia (50%). Vitamin C has an important role in increasing absorption of iron in the body which can indirectly affect the increase in Hb formation. This study was conducted to determine whether iron and vitamin C supplementation affect the changes of Hb levels in women. This study was done by quasi experimental with single blind pretest posttest control group and with a stratified random sampling technique. Respondents were female students in Faculty of Medicine UNIKA Atma Jaya. The total number of sample was 58 which was categorized into two groups. The first group was given iron and vitamin C supplementation. The second was only given iron supplementation. There were 16 respondents (27,6%) aged 16-18 and 42 respondents (72,4%) aged 19-21. The average change in Hb level before and after intervention in group 1  was 1,934 g/dL, and P = 0,000 (P <0,05), the average change in Hb level before and after intervention in group 2 was 1,086 g/dL, and P = 0,000 (P <0,05). The difference of change in Hb levels in groups 1 and 2 had an average of 0,848 g/dL, and P = 0,005 (P <0,05). For conclusion, Iron and vitamin C supplementation has a greater impact on the changes of Hb levels compared to iron supplementation only.
