Changes in Brazil
Modification in the dietary pattern
•Reduction in the consumption of traditional foods
•Increase in the consumption of processed foods

Changes in Brazil Prompted for the realization of a
nationwide dietary surveyo to picture the food intake at
the individual level
Designed:Ministry of Healthresearchers from diverse universities Brazilian Institute of Geography and Statistics (IBGE)

Sampling Two-stage cluster
samplingoCensus tractsoHouseholds
HES sample: 68,373 households
estimated IDS sample: 25%
subjects included in the IDS: 34,032
29 excluded
households included in the IDS: 13,659
non response: 19%
All census tracts selected for main
sample were represented in the IDS sample
Equally allocated among the four quarters of the
survey to reproduce seasonal variations

Data collection Nine days:oFirst day: general information on the
household and residents• Forms to include information on food acquisition and consumption
oFrom the second to the eighth days:• Interviewers visit the household to follow the filling of the forms▫Two non consecutive food records
oNineth day: closing

•Food records ▫foods and drinks consumed
time amount place of intake (inside or outside home) preparation mode
▫consumption of sugar / artificial sweeteners
▫water drinking and nutritional supplements = not collected

Validation study Study compared energy intake estimated
by the application of the IDS method against energy expenditure estimated by DLWoMean underreport: 17%
