Malnutrition is associated with childhood diseases such as diarrhea or other severe illness. Children who suffer from
repeated episodes of diarrhea are more likely to suffer from malnutrition. In addition, the source of drinking water is
a very important factor affecting the nutritional status. The objective of this study was to find out the prevalence of
malnutrition condition among children aged 3 to 5 years old and the factors associated with it. A cross sectional study
using simple random sampling was conducted among 220 children aged 3 to 5 years old from four kindergartens in
Baghdad city, Iraq. Nutritional assessment was carried out using the indicator weight-for-age z-score based on World
Health Organization cut off points. Acute malnutrition was found in 18.2 % of the respondents. In this study 65 % of
the respondents used tap water to drink as compared to 35 % who used sterilized bottles as source of drinking water.
The environmental factors mainly the source of drinking water was significantly associated with child nutritional
status (p=0.034). The prevalence of diarrhea and admissions to the hospital due to diarrhea were also significantly
associated with malnutrition (p < 0.01, p
