ABSTRACT: To determine the relative validity of a newly developed iron intake assessment tool, designed specifically to assess iron, calcium and vitamin C intake.
Estimates of iron, calcium and vitamin C intake from a computerised iron intake assessment tool compared with those from 11-day estimated dietary records.
Region of Ghent (N= +/- 225,000), a city in Flanders, the Dutch-speaking part of Belgium.
In all, 50 women aged 18-39 y, participating in a large-scale epidemiological study on iron intake and iron status.
Mean dietary iron intake from the 11-day food record, the unadjusted dietary iron intake assessment tool and the adjusted tool was, respectively, 10.5 +/- 2.7, 10.4 +/- 4.3 and 9.6 +/- 2.9 mg. For the different nutrients, the correlation coefficients vary from 0.45 to 0.60 for adjusted intake. The mean difference of iron intake by the two methods (0.8 +/- 2.9 mg) did not differ significantly from zero. The new method correctly classified 38% (iron), 38% (calcium) and 58% (vitamin C) of the subjects to the correct tertile. The correlation coefficients ranged from 0.48 for adjusted vitamin C intake to 0.73 for adjusted calcium intake between two administrations.
The newly developed instrument can be used to assess mean group intakes of iron, calcium and vitamin C in women consuming a Western diet. However, since the ranking capability of the new tool is rather weak, further refinement of the tool is required to produce a robust method for assessing iron, calcium and vitamin C intakes of individuals.
This research was supported by the Belgian National Fund for Scientific Research/Flemish Division (Fund No G.0152.01).

ABSTRACT: To describe the energy and macronutrient intake and the meal patterns of Flemish adolescents, aged 13-18 y.
A 7 day estimated food record was administered to the whole sample.
Secondary schools in the city of Ghent, Belgium.
A total of 341 adolescents (13-18 y) selected by a multistage clustered sampling (participation: 72.7%).
A significant increase with age was observed in total energy intake in adolescent boys (P<0.01), but not in girls. The energy distribution over the macronutrients showed no significant difference between boys and girls. On average, 35.7% (s.d. 4.81%) of energy came from total fat and 15.4% (s.d. 2.46%) from saturated fatty acids; 49.0% (s.d. 5.28%) from total carbohydrates with 25.1% (s.d. 4.49%) from complex carbohydrates and 23.9% (s.d. 5.86%) from free sugars. The energy contribution of alcohol in the 16-18 y-old-group was significantly higher as compared with the 13-15 y-old-group, for both boys and girls. Snacks between meals accounted for almost 20% of the total energy intake. Lunch and dinner were characterized by high total fat content.
These students consumed a diet high in total fat and in saturated fatty acids and also high in mono- and disaccharides. Observed mean intakes deviate considerably from the Belgian dietary guidelines. A low energy intake at breakfast was observed, while a higher proportion of energy was derived from snacks.

ABSTRACT: The aim of this study was to describe the dietary fat intake during pregnancy and to study the relationship between the intake of polyunsaturated fatty acids (PUFAs) and the fatty acid composition of maternal and umbilical plasma phospholipids (PLs) and cholesterol esters (CEs) at delivery. In addition, the contribution of food groups to the intake of total fat and fatty acids in the diet was quantified.Maternal and umbilical blood samples were collected at delivery from 30 healthy pregnant women. The women completed a food frequency questionnaire during the first and third trimesters. The total fat intake during pregnancy is 85 (SD 24) g/day. The mean intake of saturated fatty acids (SFAs) is 33.4 g/day, of monounsaturated fatty acids (MUFAs) 28.6 g/day and of PUFA 15.2 g/day. Major sources of fat, MUFA and PUFA are fats, oils and sauces. Major sources of SFA are meat and poultry followed by cheese and eggs. Meat and poultry contribute the most to the intake of 20:4n-6 whereas fish is the major source of 20:5n-3 (EPA) and 22:6n-3 (docosahexaenoic acid (DHA)) in the diet. Linoleic acid, EPA and DHA (w%) in PL of maternal plasma are positively related to the intake of these fatty acids during pregnancy. No association is found between the maternal intake of the two parent essential fatty acids (18:2n-6 and 18:3n-3) and their fraction in umbilical PL or CE. EPA and the sum of n-6 fatty acids (w%) in umbilical plasma PL are positively correlated with the dietary intake of these fatty acids.

ABSTRACT: To describe 5-year changes of mental health in SENECA participants, and to examine whether mental health is associated with the status of vitamin B12 and folate.
A longitudinal, multicentre study including a Baseline study, a Follow-up study, and a Finale study.
Inhabitants of 11 European towns, born between 1913 and 1918, were randomly selected at baseline to participate in the SENECA study. Of the 1099 enrolled subjects in the Follow-up study, 586 participated in the Finale study.
Mental health status was assessed by the Mini-Mental State Examination (MMSE, cognitive impairment defined as MMSE<23) and the 15-item Geriatric Depression Scale (GDS, depression defined as GDS>5).
In the Finale study, mean overall MMSE score was 26.1 for men and 25.6 for women, while mean overall GDS score was 3.1 for men and 4.1 for women. Among subjects that participated in both the Follow-up and the Finale study, MMSE scores decreased with 0.9 points (P<0.0001) and 1.0 points (P<0.0001) among men and women respectively. The GDS scores decreased with 0.7 points (P<0.0001) for men and 0.8 points (P<0.0001) for women. Among subjects that participated in the Finale study, no significant correlations have been observed between mental health and vitamin B12/folate status.
In the Finale study, mental health of the majority of the SENECA participants remained intact. In contrast to the Follow-up study, no associations between mental health and vitamin B12/folate status were emerged.

ABSTRACT: Assess longitudinal (10-y) changes in height, body weight and circumferences in elderly Europeans.
Longitudinal assessments including baseline measurements taken in 1988/1989 which were repeated in 1993 (follow-up) and in 1999 (Finale).
Longitudinal data were collected in nine European research towns: Hamme/Belgium (H/B), Roskilde/Denmark (R/DK), Haguenau/France (H/F), Romans/France (R/F), Padua/Italy (P/I), Culemborg/the Netherlands (C/NL), Vila Franca de Xira/Portugal (V/P), Betanzos/Spain (B/E), Yverdon/Switzerland (Y/CH).
Using standardised methodologies data were collected from a random stratified sample of elderly men and women born between 1913 and 1918 including a total of 662 subjects in 1999.
On average stature had decreased by 1,5-2 cm. Mean weight changed by -2.6 kg to - 4.2 kg in only three towns. An increase of at least 5 kg of body weight had taken place in 13 % of both men and women whereas 23 % of men and 27 % women had lost at least 5 kg of their baseline weight. Such weight loss over the first 4 years of follow-up was associated with higher mortality rates in men (crude RR 2.2, p<0.0001). Serial changes in arm circumference were small but waist circumference had increased by 3-4 cm.
Whilst small-to-modest average changes in height, body weight and circumferences emerged over SENECA's 10-year follow-up period, considerable gains and losses of body weight had occurred in a significant proportion of the SENECA populations, whereby early weight loss might be predictive of subsequent survival.

ABSTRACT: Background: The EURRECA (EURopean micronutrient RECommendations Aligned) Network of Excellence collated current micronutrient recommendations. A user-friendly tool, Nutri-RecQuest, was developed to allow access to the collated data and to create a database source for use in other nutritional software tools. Methods: Recommendations, that is, intakes of micronutrients sufficient to meet the requirements of the majority of healthy individuals of that population, from 37 European countries/organizations and eight key non-European countries/regions comprising 29 micronutrients were entered into a database. General information on the source of the recommendations, as well scientific background information, was added. Results: A user-friendly web-based interface was developed to provide efficient search, comparison, display, print and export functions. Conclusion: Easy access to existing recommendations through the web-based tool may be valuable for bodies responsible for setting recommendations, as well as for users of recommendations including scientists, policy makers, health professionals and industry. Adding related dietary reference values such as average nutrient requirements and upper limits may extend the utility of the tool

ABSTRACT: This study evaluated the reliability and validity of a Belgian computerized questionnaire to measure fat intake. A total of 86 adults completed a 48-item computerized fat intake questionnaire, subsequently kept a 7-day diet record, and finally completed the questionnaire again. For validity, a Pearson correlation of 0.67 for total fat intake and of 0.60 for percent energy from fat were found between the computerized questionnaire and the diet records. Gross misclassification between the two methods was 5.8% for total fat intake and for percent energy from fat. Cohen's kappa values were respectively 0.27 and 0.29. For reliability, intraclass correlation coefficients ranged from 0.70 to 0.87 between the two administrations of the computerized fat intake questionnaire. Gross misclassification between the administrations was 1.2% for total fat intake and for percent energy from fat, kappa values were respectively 0.64 and 0.50. These results indicate that this fat intake questionnaire has an acceptable reliability and validity. (C) 2004 Elsevier Inc. All rights reserved.

ABSTRACT: Objectives: The EURRECA Network of Excellence is developing standardized methods that will guide the alignment of micronutrient reference values (RVs) across Europe. A consultation process to identify and prioritize the best practice, ‘tools’ or guidance for EURRECA was undertaken. Subjects/Methods: A questionnaire was sent to 90 individuals with experience of setting or using RVs. Respondents were asked to rank the usefulness of each type of possible guidance. Results: In all, 52% of individuals returned completed questionnaires. For the planning process, the most needed guidance was on the best way to assess the ‘status quo’ of RVs; what to cover, setting priorities, how to take into consideration the diverse needs of the users; and making the whole process transparent. The most needed guidance for the active stage of development was how to obtain valid and robust data on intakes and status to use as a base for RVs; how to account for food-related factors; how to incorporate results of systematic reviews; how to identify unbiased and independent reviews and make decisions if evidence is conflicting; methods to ‘weight’ the evidence; and formats or concepts to convert scientific requirements into RVs. Users of RVs required guidance on communication, codes of practice to raise professional and public awareness, making them easy to use in the intended way. Conclusions: The questionnaire responses provided views from a wide range of experts on the most needed ‘tools’ and standardized methodologies for the process of reviewing micronutrient RVs. This will help the EURRECA Network of Excellence to prioritize resources

ABSTRACT: Acrylamide has recently been found in a range of heat treated food items. As it is a neurotoxic agent and a probable, human carcinogen (IARC 2A), human exposure to this chemical might constitute an important public health issue. The purpose of the study was to estimate the acrylamide intake in Flemish adolescents (based on 7-day food record) and to evaluate the possible health risks due to the exposure. The Belgian Federal Agency for the Safety of the Food Chain collected 150 food items from different supermarkets and restaurants to analyse the acrylamide level. The limit of quantitation was 30 μg acrylamide/kg foodstuffs. Exposure modelling was based on Monte Carlo simulations. The estimated dietary intake of acrylamide per person given as the 5th, 50th and 95th percentile were 0.19, 0.51 and 1.09 μg/kg bw/d. Bread, despite its low acrylamide content, is relevant as a source of acrylamide exposure at the lower percentiles. At higher percentiles the contribution of French fries and crisps is more important. It must be emphasised that the exposure assessment has several limitations. Risk of neurotoxicity seems negligible. The relevance of current intake levels in terms of cancer risk remains a subject of debate.
