Malnutrition in childhood is a dramatic indicator of poor socio-economical status worldwide. To recognize and reveal the socio-demographic features is crucial, especially for developing countries. Our aim was to investigate the prevalence and association with sociodemographic variables of malnutrition in 0-5 years old children in Van, Turkey. A total of 702 children are included in this cross-sectional study. Demographic features of subject including age, gender. family characteristics and other data were obtained. Nutritional assessment was done using anthropometric indices including weight for age, height forage, weight-for-height, head circumference and body mass index-for-age. Multivariate logistic regressions were carried out to assess malnutrition -associated factors. Prevalence of underweight, stunting and wasting were 19.7, 17.7 and 16.2%, respectively. Socio-demographic variables that statistical significantly in association with malnutrition were low monthly family income educational level and employment status of father, parental consanguinity, number of pregnancies, regular intake of vitamin D and history, of prematurity The prevalence of children with head circumference-z score S-2SD and body mass index forage 2SD were 9.8 and 16.3%. respectively. Multivariate analysis detected following risk factors for these indices: low monthly family income, history of prematurity, unemployed father and the period between pregnancies (12 years). We found that prevalence of malnutrition in the city of Van, was still higher than more developed regions of Turkey. The associated risk factors of malnutrition should be specifically interpreted by health professionals and also by government authorities that are responsible for making practical politics of public health.
