“…The main aim of the project was to assess the habitual consumption of vegetables, potatoes, fruit, bread and fish with a unified method in the Nordic and Baltic countries as well as to rank individuals in order to estimate for example, regular, low and high consumers. The methodological aim was to produce and validate a food frequency questionnaire (FFQ) for the Nordic and Baltic countries that would effectively record the frequency of consumption of some foods suggested by the EU/EFCOSUM (European Food Consumption Survey Method)group as dietary health indicators (Steingrímsdó ttir et al, 2002).…”

Objective: To measure the validity and reproducibility of the NORBAGREEN food frequency questionnaire (FFQ). Subjects/methods: In Finland, 125 subjects aged 25-64 years sampled from the five main regions of the FINDIET 2002 Study and in Lithuania, 99 citizens of Kaunas aged 19-75 years participated in the study. Reference methods for the FFQ were two 3-day FFQs in Finland and four 24-h recalls in Lithuania. The FFQ was repeated after 6-8 months in both countries. The outcome of the FFQ1 was correlated with the outcome of the reference methods and with the outcome of repeated FFQ2. Crossclassification of food intakes by FFQ1 and the reference methods was examined in tertiles. Results: Validity correlations (FFQ vs the reference method, Spearman's correlation) were for vegetables, fruit and bread 0.50 (Po0.01), 0.53 (Po0.01) and 0.54 (Po0.01) in Finland; and 0.55 (Po0.01), 0.31 (Po0.01) and 0.51 (Po0.01) in Lithuania, respectively. Correlations were smaller for potatoes and fish. The overall proportion categorized in the same or adjacent intake tertiles with the two instruments was over 83% in both countries. Reproducibility correlations varied between 0.51 and 0.75 in the Finnish study, and between 0.51 and 0.83 in the Lithuanian study. Conclusions: The NORBAGREEN FFQ can be used to rank subjects according to vegetable, fruit and bread consumption. Questions on fish and potato consumption need to be developed further.

“…The choice of vegetables and total fat was motivated by the desire to illustrate the effects for one food group and one nutrient both belonging to the relevant nutrition indicators identified in the EFCOSUM project (Steingrímsdó ttir et al, 2002). To evaluate and compare the efficacy of the methods we needed a sufficiently large number of repeated short-term measurements.…”

Estimating the distribution of usual dietary intake by short-term measurements

Objective: To estimate the habitual dietary intake distribution in a population on the basis of repeated short-term measurements, especially of multiple 24 h diet recalls. Methods: Six different statistical methods were evaluated and compared. The comparison referred to theoretical assumptions, admitted data transformations, statistical foundations, available software packages, and applications to real data of dietary intake. Results: The Nusser method and a simplified version of it proposed in the paper have proved to be universally applicable methods for estimating the usual intake distribution for food groups and nutrients. Also, the Buck method seemed to be a robust estimation procedure suitable for the description of food consumption data, whereas the other considered methods were only applicable for log -normally distributed intake data or required a comprehensive data simulation. Characteristics of the estimated usual intake distribution were a decreased standard deviation, increased lower percentiles, and decreased upper percentiles compared to the observed sample distribution of individual means. Empirical results concerning total fat and vegetable intake in three different European consumption surveys showed that the estimated percentiles of the usual intake distribution did not depend markedly on the number of sampling days. Conclusions: Repeated short-term measurements like 24 h diet recalls can be used to describe the habitual dietary intake distribution in food consumption surveys. Recommended is a sampling design of two non-consecutive sampling days. The sampling days of all participants should be selected in such a way that they cover all seasons and days of the week.

“…As a first step it is recommended to (find funds to) carry out a small pilot study starting with making consumption data of vegetables, fruit, bread and fish comparable. The choice of these foods follows logically from the list of most relevant dietary indicators identified by EFCOSUM (Steingrímsdó ttir et al, 2002). An important conclusion from EFCOSUM was that it is at present not possible to make existing food consumption data comparable at the nutrient level.…”

Objective: To discuss the general outcome and conclusions of a European project (EFCOSUM); to develop a method for a European food consumption survey that delivers internationally comparable data on a set of policy relevant nutritional indicators. Design and methods: The EFCOSUM project was carried out within the framework of the European Health Monitoring Programme by 14 Member States as well as nine other European countries. Activities of the project included plenary sessions, desk research and working group activities, building on existing experience from such projects as DAFNE, EPIC, FLAIR EurofoodsEnfant project, COST Action 99 and others. All participating states took part in one or more working group activities, which were discussed, adapted and finally approved in plenary sessions. Results and conclusions: For a limited number of countries available food consumption data can be made comparable at the food intake level, but not at the nutrient level. To achieve comparability at the food intake level, a considerable amount of work still has to be done. A minimum list of dietary indicators considered to be the most relevant to be collected for the Health information exchange and monitoring system was identified. As the most suitable method to get internationally comparable new data on population means and distributions of actual intake the 24 h recall was selected, to be conducted at least twice. This also allows for the estimation of usual intake by a modelling technique that separates intra-and inter-individual intake. For a number of micronutrients the use of biomarkers is recommended. Aspects of food classification and food composition were discussed thoroughly, as well as statistical and data collection aspects. For the implementation of a pan-European survey the establishment of a European co-ordinating centre is recommended. The standardization of field work work procedures and other aspects of operationalization have been discussed in detail. It is concluded that there is broad European consensus on the most suitable method for a pan-European dietary survey for the purposes of the EU Health Monitoring Programme. It is further concluded that such a pan-European survey is feasible, if the funds are made available.
