Women (n 160) aged 50 to 65 years were asked to weigh their food for 4 d on four occasions over the period of 1 year, using the PETRA (Portable Electronic Tape Recorded Automatic) scales. Throughout the year, they were asked to complete seven other dietary assessment methods: a simple 24 h recall, a structured 24 h recall with portion size assessments using photographs, two food-frequency questionnaires, a 7 d estimated record or open-ended food diary, a structured food-frequency (menu) record, and a structured food-frequency (menu) record with portion sizes assessed using photographs. Comparisons between the average of the 16 d weighed records and the first presentation of each method indicated that food-frequency questionnaires were not appreciably better at placing individuals in the distribution of habitual diet than 24 h recalls, due partly to inaccuracies in the estimation of frequency of food consumption. With a 7 d estimated record or open-ended food diary, however, individual values of nutrients were most closely associated with those obtained from 16 d weighed records, and there were no significant differences in average food or nutrient intakes.

Dietary Assessment Methods

Within the EURopean micronutrient RECommendations Aligned Network of Excellence (EURRECA), a scoring system was developed to assess the quality of dietary intake validation studies. The scoring system included three steps. The first step was to give each study a quality score, which included five components: sample size, statistics used, data collection procedure, consideration of seasonality and supplement use. Scores ranged from 0 to 7, and validation studies classified as very good ( ≥ 5), good (5–3·5), acceptable/reasonable (3·5–2·5) and poor ( < 2·5). The second and third steps included an adjustment/weighting of the correlation coefficient according to the quality score and moreover a rating of the adjusted/weighted correlation. The scoring system was tested in 124 validation studies that included at least one vitamin. Only 5·6 % of the 124 studies were judged to be of very good quality according to the quality score, 41·9 % of good quality and 16·9 % had a poor rating. When adjusting for the study quality scores, crude and adjusted mean correlations of vitamins A, C, D and E intakes were similar, but the percentage of correlation values classified as poor or very good was higher after adjustment. These results show the importance of considering the quality of studies validating dietary assessment methods and the correlations obtained for the micronutrient of interest when interpreting effects observed in epidemiological studies using dietary assessment methods. Without a doubt, this subject constitutes a key topic for research in nutritional epidemiology.

AbstractEggs tend to be eaten irregularly, e.g. they are often eaten as a standby for unplanned meals, and have been reported to be eaten as a treat or on special occasions. This intrapersonal variation may impact the accuracy of measuring the habitual intake of eggs. Food frequency questionnaires (FFQs) are often validated for nutrients but not foods, and may not be suitable for measuring the consumption of individual foods. The validity of measuring the consumption of specific foods can be particularly affected for foods with a greater within-person variation. Moreover, FFQs rarely include a detailed intake measure of eggs, and often do not include eggs in mixed dishes. With epidemiological studies focussing on individual foods to assess associations between foods and diseases, it is important to consider the accuracy of dietary assessment methods in measuring intake of individual foods.In the current study we compare egg intake data from a validated FFQ and egg intake data from an FFQ specifically designed to measure egg intake. Both questionnaires were completed by a sample of 100 community-dwelling healthy older adults, which included 54 females and 46 males, with mean age 70 (SD = 7) years. Both FFQs had a similar layout, but the validated FFQ section on egg intake consisted of three questions on egg intake, while the egg FFQ included 18 preparations of eggs, including mixed dishes.Mean monthly egg consumption for the validated FFQ was 16 (SD = 13) eggs, while the egg FFQ showed an egg intake of 22 (SD = 16) eggs per month, suggesting under- or over-reporting on one or both measures. Although the mean values are noticeably different, validated FFQ egg intake correlates strongly with egg FFQ intake (r = .773, p < .001).National Diet and Nutrition Survey data indicates that British older adults (65 years + ) consume 33 g of eggs/egg dishes per day, the equivalent of 16–17 eggs per month. This means that the validated FFQ egg intake of 16 eggs per month is more similar to the NDNS data. However, FFQs generally tend to overestimate food intake compared to diet records and the validated FFQ is validated for the total nutrient intake, not for individual foods. With only three questions and without including mixed dishes, the validated FFQ may under-estimate intake of eggs, while the egg FFQ may be more comprehensive. More research is needed to explore the most appropriate methods for measuring intakes of foods that are irregularly consumed, such as eggs.

Dietary Assessment Methods

AbstractObjectiveThe aim of the present work was to determine what dietary assessment method can provide a valid and accurate estimate of nutrient intake by comparison with the gold standard.DesignA MEDLINE, EMBASE, ISI Web of Science, Cochrane and related references literature review was conducted on dietary assessment methods for adolescents reporting the validity and/or reproducibility values. A study quality assessment on the retrieved FFQ was carried out according to two different scoring systems, judging respectively the quality of FFQ nutrition information and of FFQ validation and calibration.SettingThe present review considered adolescents attending high schools and recruited in hospitals or at home.SubjectsThe target of the review was the healthy adolescent population in the age range 13–17 years.ResultsThirty-two eligible papers were included and analysed separately as ‘original articles’ (n20) and ‘reviews’ (n12). The majority (n17) assessed the validation and reproducibility of FFQ. Almost all studies found the questionnaires to be valid and reproducible (r> 0·4), except for some food groups and nutrients. Different design and validation issues were highlighted, such as portion-size estimation, number of food items and statistics used.ConclusionsThe present review offers new insights in relation to the characteristics of assessment methods for dietary intake in adolescents. Further meta-analysis is required although the current review provides important indications on the development of a new FFQ, addressing the need for a valid, reproducible, user-friendly, cost-effective method of accurately assessing nutrient intakes in adolescents.

For nutrition practitioners and researchers, assessing dietary intake of children and adults with a high level of accuracy continues to be a challenge. Developments in mobile technologies have created a role for images in the assessment of dietary intake. The objective of this review was to examine peer-reviewed published papers covering development, evaluation and/or validation of image-assisted or image-based dietary assessment methods from December 2013 to January 2016. Images taken with handheld devices or wearable cameras have been used to assist traditional dietary assessment methods for portion size estimations made by dietitians (image-assisted methods). Image-assisted approaches can supplement either dietary records or 24-h dietary recalls. In recent years, image-based approaches integrating application technology for mobile devices have been developed (image-based methods). Image-based approaches aim at capturing all eating occasions by images as the primary record of dietary intake, and therefore follow the methodology of food records. The present paper reviews several image-assisted and image-based methods, their benefits and challenges; followed by details on an image-based mobile food record. Mobile technology offers a wide range of feasible options for dietary assessment, which are easier to incorporate into daily routines. The presented studies illustrate that image-assisted methods can improve the accuracy of conventional dietary assessment methods by adding eating occasion detail via pictures captured by an individual (dynamic images). All of the studies reduced underreporting with the help of images compared with results with traditional assessment methods. Studies with larger sample sizes are needed to better delineate attributes with regards to age of user, degree of error and cost.

Dietary Assessment Methods

People with serious mental illness (SMI) experience challenges that may make typical dietary assessment methods less feasible and accurate. This study aims to determine the feasibility, acceptability and preliminary validity of a 3-day photographic food record (PR), a 1-day food diary (FD) and a 1-day weighed food protocol (WR) in people with SMI. Participants completed measures at two timepoints, with a 4-week interval. Feasibility and acceptability for each method were measured through four outcomes: percent of completers, quality assessment, number of participants requiring technical devices and satisfaction questionnaire. Relative validity was measured by agreement in estimated energy intake between methods, using Bland–Altman analysis and WR as the benchmark, and prevalence of misreporting, using the Goldberg cut-off method, updated by Black. In total, 63 participants were recruited, with a dropout rate of 19.0% prior to timepoint 1 and additional 6.4% prior to timepoint 2. Quality deficits were identified for all methods. The FD was most acceptable to participants, followed by the PR. The difference in estimated energy intake between assessment methods was not statistically significant, though there was considerable individual variability. Underreporting was considerable across all methods but appeared highest in the PR. A FD and PR present as feasible and acceptable methods for assessing dietary intake in people with SMI. Further validity testing is required. In addition, clear guidance for completion and removal of potential barriers is required for participants.
