Zur Aussagefähigkeit zweimonatiger Lebensmittelerfassungen in Personenhaushalten

Abstract

All-year surveys of the food consumption in private households are very laborious. They may be simplified by shortening the period of time covered by the survey. 712 surveys taken in 1974 led to the conclusion that surveys covering only two months (April and August) permit to make statements the validity of which is but slightly inferior to that of an all-year survey. Of the 45 food groups considered, only 5 (potatoes, fresh vegetables, fresh fruit, tropical and subtropical fruit, and sugar) play an important role as to the selection of suitable months for such a survey.
