Household Expenditures Surveys in Brazil

ENDEF 1974-75

POF 1986-87

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

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

Page 8: Rosangela  A Pereira  1 Dirce  M L Marchioni 2 Regina M  Fisberg 2 Rosely Sichieri 3

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

Page 9: Rosangela  A Pereira  1 Dirce  M L Marchioni 2 Regina M  Fisberg 2 Rosely Sichieri 3

•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

Page 10: Rosangela  A Pereira  1 Dirce  M L Marchioni 2 Regina M  Fisberg 2 Rosely Sichieri 3

Validation study Study compared energy intake estimated

by the application of the IDS method against energy expenditure estimated by DLWoMean underreport: 17%

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

Future improvements in the dietary assessment methods for nationwide IDS

To use a software to standardize the data collection
