Household Expenditures Surveys in Brazil
ENDEF 1974-75
POF 1986-87
POF 1995-96

POF 2008-09
Widely used in food consumption monitoring
Changes in Brazil
Modification in the dietary pattern
•Reduction in the consumption of traditional foods
•Increase in the consumption of processed foods
•Increase of away-from-home eating
Increasing prevalence of
food and nutrition related
disorders
•Obesity•Cardiovascular diseases•Diabetes•Cancer
Changes in Brazil Prompted for the realization of a
nationwide dietary surveyo to picture the food intake at
the individual level

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

countryTraining on procedures to use the data
Future improvements in the dietary assessment methods for nationwide IDS* To include other information in order to better estimate
food consumption and characterize eating habits
Occasion of consumption breakfast, snack, lunch, dinner, supper, brunch, other
Away-from-home local of consumptionRestaurant, bar etc
