Abstract
To estimate the prevalence of cardiovascular risk factors, including those included in the definition of the metabolic syndrome, in a random sample of adolescents aged 12 to 17 years from public and private schools.

Sample survey data [ssd]
Unit of Analysis

Scope

Notes
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. The population group covered in the survey was adolescents aged 12 to 17 years old.

Sampling

Sampling Procedure
The study population was stratified into 32 geographical strata (27 capitals and five sets with other municipalities in each macro-region of the country) and a sample of 1,251 schools was selected with probability proportional to size. In each school three combinations of shift (morning and afternoon) and grade were selected, and within each of these combinations, one class was selected. All eligible students in the selected classes were included in the study. The design sampling weights were calculated by the product of the reciprocals of the inclusion probabilities in each sampling stage, and were later calibrated considering the projections of the numbers of adolescents enrolled in schools located in the geographical strata by sex and age. Levels of representativeness: Brazil, Brazilian Macrorregions, Brazilian State Capitals, Urban and Rural Location.
Weighting
The sample of ERICA is considered a complex sample, since it uses stratification, clustering and unequal probabilities in its selection stages. Unbiased (or at least approximately unbiased) point estimates of target population parameters may be calculated with the use of calibrated sampling weights by any statistical system that accepts weighting. The recommended sampling weight is the calibrated weight, but the design weight is included in the files to allow replication of the calibration process in case the survey library is used.

Data Collection Notes
Primary dietary assessment method: 24-hour recall, covering both week days and weekends. A second recall was collected after an average of 7-10 days for 5038 subjects. Secondary dietary assessment method: Screeners about fish, diet or light foods, alcohol intake, in order to have more details about the intake of those food groups.
