“…An FFQ is much easier to apply than a dietary history, but like 24-h recalls, it is often not used in elderly people because it relies on memory (van Staveren et al, 1994). On the other hand, no strong evidence exists that elderly people provide less valid self-reports using these methods compared with younger populations.…”

“…We chose this method because older residents in these homes often suffer from cognitive decline, which make FFQs, 24-h recalls or other methods relying on memory, less reliable (van Staveren et al, 1994).…”

“…To choose an appropriate dietary assessment method, several aspects have to be taken into consideration (van Staveren et al, 1994). Studies have different purposes requiring the assessment of dietary intake on the individual or group level: studying nutrients, foods or dietary patterns; or investigating associations with the outcome of disease or the adequacy of intake.…”

Background/Objectives: In selecting a dietary assessment method, several aspects such as the aim of the study and the characteristics of the target population should be taken into account. In elderly people, diminished functionality and cognitive decline may hamper dietary assessment and require tailored approaches to assess dietary intake. The objective of this paper is to summarize our experience in dietary assessment in a number of different studies in population groups over 65 years of age in the Netherlands, and to discuss this experience in the perspective of other nutrition surveys in the elderly. Methods: In longitudinal studies, we applied a modified dietary history; in clinical nursing home studies, trained staff observed and recorded food consumption; and in a controlled trial in healthy elderly men, we used a food frequency questionnaire (FFQ). Results: For all methods applied in the community-dwelling elderly people, validation studies showed a similar underestimation of intake of 10-15% compared with the reference value. In the care-depending elderly, the underestimation was less: 5% according to an observational method. The methods varied widely in the resources required, including burden to the participants, field staff and finances. Conclusions: For effective dietary assessment in older adults, the major challenge will be to distinguish between those elderly who are able to respond correctly to the less intensive methods, such as 24-h recalls or FFQ, and those who are not able to respond to these methods and require adapted techniques, for example, observational records.

“…Additionally, various factors may interfere with the cognitive process of retrieving and recalling information. They include the characteristics of the study subjects such as gender (Karvetti & Knuts, 1985;Johnson et al, 1994;Smith et al, 1994;Klesges et al, 1995;Briefel et al, 1997), age (Karvetti & Knuts, 1985;van Staveren et al, 1994;Poon, 1985;Nolan & Blass, 1992), level of education or ethnic group (Klesges et al, 1995), and the general setting of the interview (Krall et al, 1988). The perception of what is à healthy diet' also leads to social desirability bias.…”

Objectives: Despite increasing interest in the concept of calibration in dietary surveys, there is still little experience in the use and standardization of a common reference dietary method, especially in international studies. In this paper, we present the general theoretical framework and the approaches developed to standardize the computer-assisted 24 h diet recall method (EPIC-SOFT) used to collect about 37 000 24-h dietary recall measurements (24-HDR) from the 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). In addition, an analysis of variance was performed to examine the level of standardization of EPIC-SOFT across the 90 interviewers involved in the study. Methods: The analysis of variance used a random effects model in which mean energy intake per interviewer was used as the dependent variable, while age, body mass index (BMI), energy requirement, week day, season, special diet, special day, physical activity and the EPIC-SOFT version were used as independent variables. The analysis was performed separately for men and women. Results: The results show no statistical difference between interviewers in all countries for men and ®ve out of eight countries for women, after adjustment for physical activity and the EPIC-SOFT program version used, and the exclusion of one interviewer in Germany (for men), and one in Denmark (for women). These results showed an interviewer effect in certain countries and a signi®cant difference between gender, suggesting an underlying respondent's effect due to the higher under-reporting among women that was consistently observed in EPIC. However, the actual difference between interviewer and country mean energy intakes is about 10%. Furthermore, no statistical differences in mean energy intakes were observed across centres from the same country, except in Italy and Germany for men, and France and Spain for women, where the populations were recruited from areas scattered throughout the countries. Conclusion: Despite these encouraging results and the efforts to standardize the 24-HDR interview method, conscious or unconscious behaviour of respondents andaor interviewer bias cannot be prevented entirely. Further evaluation of the reliability of EPIC-SOFT measurements will be conducted through validation against independent biological markers (nitrogen, potassium).

“…Furthermore, due to increased morbidity and mortality, endpoints in the older category will occur per person year of follow-up more often than at younger ages 1 . However, it is well known that there are also problems in surveying older people 2 . Fading memory is a problem in older adults for reporting on food consumption patterns.…”

Objective: To give an overview of the evaluation of the modified diet history applied in the SENECA study (Survey in Europe on Nutrition and the Elderly; a Concerted Action). Design: Nineteen centres in 12 countries participated at baseline. Nine of these SENECA centres conducted a repeat measurement scheme in elderly people born between 1913 and 1918. These longitudinal centres included 100 subjects per sex per site. Methods: The relative validity of the method was tested by comparing results of the modified diet history with results obtained from a weighed record in 82 subjects. In the follow-up we compared changes in energy intake with changes in body weight and calculated the physical activity ratio in all longitudinal centres. In SENECA's finale we examined the predictive value of dietary patterns observed at baseline for survival 10 years later, making use of the original and an adapted Mediterranean Diet Score. Results: The modified diet history overestimated intake, compared with the weighed record. However, the physical activity ratio and an in-depth study in a metabolic room indicated that the diet history rather underestimated energy intake. We did not find a relationship between changes in energy intake and changes in body weight, but this could be explained by the fact that most likely we did not measure intake in the dynamic phase of body weight change. Based on the adapted Mediterranean Diet Score, the study results showed a positive relation between a healthy diet and survival. Conclusion: We conclude that the modified diet history has given sufficiently reliable results for the purposes of the study.
