Globally, the proportion of children under five who are underweight declined by one fifth over the period 1990-2005. Eastern Asia showed the greatest improvement and is surpassing the MDG target, largely due to nutritional advances in China. Western Asia and Latin America and the Caribbean have also demonstrated significant progress, with underweight prevalence dropping by more than one third. The greatest proportions of children going hungry continue to be found in Southern Asia and sub-Saharan Africa.
