Individual Food Consumption/Dietary Survey [hh/ifcs]
The aim of the Mexican National Health and Nutrition Survey (ENSANUT, Encuesta Nacional de Salud y Nutrición) 2012 was to quantify the frequency, distribution, and trends of health and nutrition conditions and their determinants.
Sample survey data [ssd]
Individuals.
Scope
The survey collected information on:
- SUBJECTS: information on the participants such as age, sex and geographical location
- CONSUMPTION: information on all foods consumed by each participant in each survey day, including quantities and nutrient values
Coverage
National coverage, both urban and rural areas.
General population, aged 0-104 years old, was covered in the survey.

Sampling
ENSANUT 2012 used a stratified multistage sample. The primary sampling unit was the basic geostatistical areas (AGEB, Áreas Geoestadísticas Básicas), which are census units in Mexico. The sampling frame was constructed with information from the Count of Population and Housing (CONTEO, Conteo de Población y Vivienda) 2005, complemented with the list of newly created localities identified for the Census of Population and Housing (CPV, Censo de Población y Vivienda) 2010.
Since the sample of the ENSANUT 2012 is not self-weighted, a survey weight was calculated for each survey participant. Initial weights were derived using the age and sex distribution of the CPV 2010 population, because several health conditions are associated with these variables. The final weights account for the complex survey design as well as for survey nonresponse. The weights were used throughout all analyses. Thus, to ensure appropriate estimation of precision, all survey estimates must incorporate survey weights and sample design.
The use of the weights and the variables "EST_VAR" and "CODE_UPM" are very important to adequately reflect the characteristics of the population.
As example: svyset [pweight = pondef], strata (est_var) psu (code_upm) singleunit (centered). Where the pondef variables are "WEIGHTING_FACTOR" (final weight for diet data) and "S_W_ANTHRO" (final weight for anthropometry data). The choice of the weighting is defined by the research question.

The individual quantitative 24-hour recall method was used for data collection. Two repeated dietary recalls were collected for 929 subjects, with an average of 2 days between the subsequent recalls. Both weekdays and weekends were covered in the survey.
People aged 15 years or older were asked about their intakes. The person in charge of food preparation and distribution in the household was asked about ingredients and recipes of foods prepared at home and also provided information on the intakes of children less than 15 years old. A food frequency questionnaire was also administered.
