Individual Food Consumption/Dietary Survey [hh/ifcs]
Abstract
The survey was conducted, in order to:
1. Estimate the energy and nutrient intake in a population aged 6-35 months.
2. Estimate the population with adequate consumption of energy and nutrients in the population aged 6-35 months.
3. Report the nutritional status indicators: anemia, chronic malnutrition and overweight/obesity, in the population under 36 months of age.
4. Report on the quality of water for human consumption in the homes of the study population, in the population under 36 months of age.

Sampling
Sampling Procedure
For the sample selection, 14 strata were built combining areas (Metropolitan Lima and Callao, Urban and Rural Rest) and the district poverty quintile. In each stratum, a multiple of 4 clusters was selected by random sampling without replacement and with probability proportional to the total size of inhabitants. 79 of the 80 selected clusters were executed, each of approximately 50-100 households where eight teams worked for 13 weeks in the last quarter of 2015.
In order to reduce systematic errors, in each area they were randomly permuted to assign them to the teams and weeks. In each conglomerate, the random selection of the assigned day was prepared for each of the 10 children of the sample quota. Field teams performed a quick enumeration of the total number of eligible children. When the total was greater than 10, the first 10 were selected according to a pre-selected and different random sequence for each cluster. When the total was less than 10, we worked with all of them and it was not necessary to look for replacements.
The sample size was estimated by stratified and multistage random sampling in three domains (Metropolitan, Urban and Rural Lima). The sampling frame consisted of information on population and housing from the 2007 National Censuses: XI on Population and VI on Housing, available at the National Institute of Statistics and Informatics (INEI).

Data Collection Notes
The method used for the consumption study was the 24-hour Reminder (R24H) on two non-consecutive days. The second measurement was made in a subsample made up of one child for each of the clusters visited. The selection of the days considered all the days of the week, the date of the second visit was random starting after two non-consecutive days of the first visit.
Detailed information was collected on the forms on everything the child consumed the day before, including whether she consumed it in the Cuna Más day care program or another social program from government, parochial, or private institutions.
For the estimation of the weight of the food, several resources were used: the weighing of similar foods in the home, the identification of the food by means of a laminar of homemade measures and the use of measuring jugs and the same kitchenware of the family for the estimation of the weight of liquids. To estimate the net weight consumed, lists of equivalences of household measures of food and preparations were used, as well as auxiliary tables to determine the edible part and from raw to cooked food. All the procedures were registered in the formats for their later criticism and audit. Details are developed in the Interviewer's Manual.
