Rev Peru Med Exp Salud Publica [online]. 2011, vol.28, n.2, pp. 210-221. ISSN 1726-4634.  http://dx.doi.org/10.1590/S1726-46342011000200007.

Objectives. To describe the design and methods of the national surveillance of nutritional indicators (MONIN) 2007-2010, carried out by INS/CENAN. Materials and 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.
