The prevalence of stunted children was higher in the poorest groups in almost all countries in which recent nutrition survey data was available.5 In some countries, the prevalence among the poorest group was nearly twice the national average (Figure 9). While the prevalence of overweight children is greater in higher-income groups in most countries, the poorer groups had higher prevalence in Armenia and Serbia. Malnutrition - both undernutrition and overweight - are multicausal problems.
