title: [Design of the National Surveillance of Nutritional Indicators (MONIN), Peru 2007-2010].
abstract: OBJECTIVE
  To describe the design and methods of the national surveillance of nutritional indicators (MONIN) 2007-2010, carried out by INS/CENAN.
  
  
  METHODS
  MONIN was designed as a continuous (repeated cross-sectional) survey, with stratified multi-stage random sampling, considering the universe as all under five children and pregnant women residing in Peru, divided into 5 geographical strata and 6 trimesters (randomly permuted weeks, about 78% of the time between November 19, 2007 and April 2, 2010).
  
  
  RESULTS
  The total sample was 3,827 children in 361 completed clusters. The dropout rate was 8.4% in clusters, 1.8% in houses, and 13.2% in households. Dropout was also 4.2, 13.3, 21.2, 55% and 29% in anthropometry, hemoglobin, food intake, retinol and ioduria measurements, respectively.
  
  
  CONCLUSIONS
  The MONIN design is feasible and useful for the estimation of indicators of childhood malnutrition.
