“…Small differences nearly inevitably appear in different surveys, and are in the case of Erfurt mainly caused by ®nancial and personal dif®culties and changes of research structures in East Germany at that time. Generally, however, little is known on these possible sources of biases, as for instance on the validity of portion size picture booklets (Cypel et al, 1997). The limitation to men aged 45±64 y in the Erfurt sample and to one Sunday and the ®rst two week days of records kept between October and March in the Augsburg sample, is a further approach to make both samples comparable and to avoid in¯uences by season and by day of the week.…”

Objective: To compare the diets of men from East and West Germany after the reuni®cation under the new food market conditions in the East. Design: Both dietary surveys were part of the third MONICA surveys in population based random samples. Results: Nutrient intakes show the pattern of a typical Western diet in both samples with 15.2 en% from protein, 39.5 en% from fat, 38.8 en% from carbohydrates and 6.2 en% from alcohol in Erfurt. Corresponding ®gures for Augsburg are 16.4 en%, 37.9 en%, 39.0 en% and 6.5 en%. Intake of animal protein, cholesterol, water and selected micronutrients is distinctly higher in Augsburg. Conclusions: Dietary differences still exist, but the pattern of difference has changed. It is unclear, whether differences between East and West exceed regional differences in the West.

“…Data from published surveys indicated that differences between the food quantity estimates obtained from different portion size measurement aids were not statistically significant (Cypel et al, 1997). Therefore, practical reasons might affect the choice.…”

Selection of methodology to assess food intake

et al. 2002

Objective: The aim of the EFCOSUM project was to develop a method to estimate both acute and usual consumption levels in European countries and for the sake of comparison, a common basic method for dietary assessment was needed. The method should allow a reliable comparison of the intake of relevant dietary indicators among large population groups. Design and results: The selection of methodology was based on the available literature and the expertise of the participants. To guide the selection process, decision trees containing all relevant moments of choice, alternatives and criteria for the selection of a method for food consumption measurement were developed. Considering that insight into average food and nutrient intake and their distribution in well-defined groups of individuals was important, it was decided that for the monitoring of the selected dietary indicators food consumption data should be collected at an individual level. Different methods were reviewed (24 h recall, dietary record, food frequency questionnaire, dietary history method). Conclusions: Since the 24 h recall method is applicable in large European populations of different ethnicity, has a relatively low respondent and interviewer burden, is open-ended and is cost-effective, this method can be considered as the best method for EFCOSUM to get population mean intakes and distributions for subjects aged 10 y and over in different European countries. Usual intake should be estimated by statistical modelling techniques, using two non-consecutive 24 h recalls and a food list to assess the proportion non-users for infrequently consumed foods.

“…It is not'the purpose of this paper to review such studies, but rather to present guidelines which may help to overcome some of the problems identhed in previous studies. (For review papers on portion sizes see Young and Nestle, 1995;Cypel et al, 1997','. ) The need for guidelines for photograph series became apparent following discussions on the validity of portion size estimates at a workshop organized by COST99 (EUROFOODS) in Norwich in April 1997.…”
