The cross sectional study with a comparison group was conducted with 1,240 children under 5 years of age at 5 provinces Dien Bien, Kon Tum, Ninh Thuan, An Giang and Dong Thap. The study results showed that nearly 1/3 of children lived with households possessing sanitary latrines, and the majority of household owning sanitary latrines belonged to the intervention group. The proportion of stunting children in the intervention group was 20.5 percent and this percentage among the control group was 36.2 percent (p0.001). The results of the binary logistic regression showed that children living in intervention communes and living in households possessing sanitary latrines had significantly lower risk of 'getting stunting malnutrition than those living in the control communes and in households without sanitary latrines.
