The key measures of child under-nutrition namely, stunting, wasting and underweight are sometimes inter-related and hence may mislead if univariate approach of analyzing the data is performed. This paper employed multivariate logistic regression model for identifying the most significant determinants of the three standard child under-nutrition measures using Bangladesh Demographic and Health Survey (BDHS, 2011) data. The analysis identified educational attainment of mother, wealth index, size of child at birth, and preceding birth interval as most responsible determinants of nutritional status of under-five children. Furthermore, this research revealed that a child may suffer from one or more form of under-nutrition and hence recommended different policy options. Overall, the findings of this report are expected to feed the policy decisions regarding child nutrition in an integrated and holistic manner.
