Mean throughout 45.63%. group with highest rate Northeast (4.08%; APC=45.76%, p<0.01) children aged 2-4 years (3.03%; APC=34.62%, p<0.01), respectively. There upward trend e-SUS APS, detriment Web. a positive HDI some groups. remains low across country. has potential be important strategy expanding nutrition surveillance.
