Egele VS, Klopp E, Stark R. Evaluating self-reported retrospective average daily fruit, vegetable, and egg intake: Trustworthy-Sometimes! Appl Psychol Health Well Being 2023; 15:1130-1149. [PMID: 36509422 DOI: 10.1111/aphw.12430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Accepted: 11/28/2022] [Indexed: 12/14/2022]
Abstract
Retrospective self-reports are commonly used to assess dietary intake. Yet, their use is criticized as it is unclear whether the underlying assumptions for valid self-reports are met: Individuals have to consider the behavior of all days in the retention interval and weigh the behavior of all days equally. This study examines whether these assumptions for retrospective self-reports are met and whether interindividual differences in self-report performance are relevant regarding these assumptions. Ninety-two participants aged 18-61 years participated in seven sequential 24-h recalls and one retrospective 7-day recall concerning their intake of fruit, vegetables, and eggs. A multiple linear regression approach was used to examine the relation between the daily reported dietary intake and the 7-day recall. In the overall sample, the requirements for retrospective self-reports were not tenable. Distinguishing good and poor self-reporters based on a rational criterion showed that the requirements can be taken as given for good self-reporters, whereas poor self-reporters base their retrospective self-reports mostly on recency effects. The underlying requirements for retrospective self-reports appear to be met in two thirds of the sample, supporting the use of retrospective self-reports to capture dietary behavior. Future research should investigate characteristics separating good from poor self-reporters.

Comparison of meal patterns across five European countries using standardized 24-h recall (GloboDiet) data from the EFCOVAL project. Eur J Nutr 2018; 57:1045-1057. [PMID: 28275868 DOI: 10.1007/s00394-017-1388-0] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2016] [Accepted: 01/25/2017] [Indexed: 01/22/2023]
Abstract
PURPOSE To examine meal patterns in terms of frequency and circadian timing of eating in five European countries participating in the EFCOVAL project. METHODS In this cross-sectional study, 559 men and women, aged 44-65 years, were recruited in Belgium, the Czech Republic, France (Southern part), The Netherlands, and Norway. Dietary data were collected by trained interviewers using standardized computerised 24-h recalls (GloboDiet). Means ± SE of (1) eating frequency, (2) overnight fasting, and (3) time between eating occasions were estimated by country using means from 2 days of 24-h recalls. We also estimated the frequency of eating occasions per hour by country as well as the proportional energy intake of meals/snacks by country compared to the mean energy intake of all countries. RESULTS Mean eating frequency ranged from 4.3 times/day in France to 7.1 times/day in The Netherlands (p < 0.05). Mean overnight fasting was shortest in the Netherlands (9.2 h) and longest in Czech Republic (10.9 h) (p < 0.05). Mean time between single eating occasions was shortest in The Netherlands (2.4 h) and longest in France (4.3 h) (p < 0.05). Different patterns of energy intake by meals and snacks throughout the day were observed across the five countries. CONCLUSIONS We observed distinct differences in meal patterns across the five European countries included in the current study in terms of frequency and circadian timing of eating, and the proportion of energy intake from eating occasions.

Comparison of food consumption and nutrient intake assessed with three dietary assessment methods: results of the German National Nutrition Survey II. Eur J Nutr 2017; 58:193-210. [PMID: 29189903 PMCID: PMC6424917 DOI: 10.1007/s00394-017-1583-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Accepted: 11/15/2017] [Indexed: 10/24/2022]
Abstract
PURPOSE Comparison of food consumption, nutrient intake and underreporting of diet history interviews, 24-h recalls and weighed food records to gain further insight into specific strength and limitations of each method and to support the choice of the adequate dietary assessment method. METHODS For 677 participants (14-80 years) of the German National Nutrition Survey II confidence intervals for food consumption and nutrient intake were calculated on basis of bootstrapping samples, Cohen's d for the relevance of differences, and intraclass correlation coefficients for the degree of agreement of dietary assessment methods. Low energy reporters were identified with Goldberg cut-offs. RESULTS In 7 of 18 food groups diet history interviews showed higher consumption means than 24-h recalls and weighed food records. Especially mean values of food groups perceived as socially desirable, such as fruit and vegetables, were highest for diet history interviews. For "raw" and "cooked vegetables", the diet history interviews showed a mean consumption of 144 and 109 g/day in comparison with 68 and 70 g/day in 24-h recalls and 76 and 75 g/day in weighed food records, respectively. For "fruit", diet history interviews showed a mean consumption of 256 g/day in comparison with 164 g/day in 24-h recalls and 147 g/day in weighed food records. No major differences regarding underreporting of energy intake were found between dietary assessment methods. CONCLUSIONS With regard to estimating food consumption and nutrient intake, 24-h recalls and weighed food records showed smaller differences and better agreement than pairwise comparisons with diet history interviews.

Abstract
OBJECTIVES To estimate agreement between questionnaire-based frequency measures from the Health Behaviour in School-aged Children study (HBSC) and 7-day 24-h recall measures of breakfast, lunch and evening meals among 11-15-year-olds, and examine whether disagreement between the two methods varied by socio-demographic factors. METHODS In one week 11-15-year-old Danish students completed HBSC questionnaires including meal frequency items. The following week they completed daily 24-h recall questionnaire about their meals (response rate 88.4 %, n = 412). RESULTS Good to moderate agreement for the breakfast measure: per cent agreement 0.70-0.87, kappa 0.43-0.65. Fair agreement for the lunch measure: per cent agreement 0.53-0.84, kappa 0.26-0.54. High per cent agreement for the evening meal measure (0.83-0.95) but poor kappa agreement (0.14-0.19). Being immigrant predicted disagreement between the two methods for week day breakfast OR (95 % CI) 2.17 (1.16-4.04) and lunch 2.44 (1.33-4.48). CONCLUSIONS We found good to moderate agreement between frequency and 7-day 24-h recall measures for breakfast, a fair agreement for lunch and for evening meal the two agreement methods provided different results. Migration status predicted disagreement between the two methods.

Abstract
BACKGROUND A new web-based food frequency questionnaire (the ASSO-FFQ) was developed within the ASSO Project funded by the Italian Ministry of Health. OBJECTIVE The aim of the present study is to assess the validity of the ASSO-FFQ at food groups, energy, and nutrients level. DESIGN AND SUBJECTS The validation study compared the ASSO-FFQ against a weighted food record (WFR) measuring foods, beverages and supplements intake, compiled during the week following the ASSO-FFQ administration. Ninety-two subjects aged 14-17, recruited from secondary schools in Palermo (Italy), completed the ASSO-FFQ and WFR. The intake of 24 food groups, energy, and 52 nutrients were taken as main outcomes. Tests for paired observations, Spearman and Pearson's correlation coefficients (cc), kappa statistics and classification in quintiles, Bland-Altman plots and multiple regressions, on untransformed and transformed data were used for the statistical analysis. RESULTS High cc (≥0.40) were found for soft drinks, milk, tea/coffee, vegetables, and lactose; fair energy-adjusted cc (0.25-0.40) for water, alcoholic drinks, breakfast cereals, fishery products, savory food, fruit juice, eggs, and 19 nutrients. The subjects classified in the same or adjacent quintile for food groups ranged from 40% (alcoholic drinks) to 100% (dried fruit); for energy and nutrients from 43% (phosphorus, thiamin, niacin) to 77% (lactose). Mean differences were not significant for water, soft drinks, meat, sweets, animal fats, milk and white bread, and vitamin B12 and folate. Limits of Agreement were broad for all food groups and nutrients. School, gender, alcohol consumption and between meals mainly affected most food groups' intake differences. Gender stratification showed females had increased Pearson's cc for energy and 28 nutrients, such as almost all fats, carbohydrates, vitamins and minerals. CONCLUSIONS The ASSO-FFQ could be applied in epidemiological studies for the assessment of dietary consumption in adolescents to adequately rank food, energy and nutrient intakes at a group level.

Comparison of food habits, iron intake and iron status in adolescents before and after the withdrawal of the general iron fortification in Sweden. Eur J Clin Nutr 2015; 69:494-500. [PMID: 25626410 DOI: 10.1038/ejcn.2014.291] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Revised: 12/05/2014] [Accepted: 12/10/2014] [Indexed: 11/09/2022]
Abstract
BACKGROUND/OBJECTIVES Sifted flour was fortified with carbonyl iron for 50 years in Sweden. This study evaluates changes in food habits, intake of iron, factors affecting iron absorption and iron status after the discontinuation of the general iron fortification in adolescents with the highest requirements. SUBJECTS/METHODS A total of 2285 15- to 16-year-old students in 1994 (634 girls and 611 boys) and in 2000 (534 girls and 486 boys) in 13 schools in Gothenburg, Sweden, were included in two cross-sectional surveys assessing food habits with diet history interviews and iron deficiency defined with serum ferritin stores ⩽ 15 μg/l and no preceding infection. RESULTS In girls, iron deficiency increased from 37 to 45%, while in boys, it was stable at 23%. Total iron intake decreased from 15.7 to 9.5 mg/day and 22.5 to 13.9 mg/day in girls and boys, respectively. Cereals were the main iron source. Among girls, the increase of fish and decrease of calcium intake may not counteract the effect of decreased intake of fortification iron. Among boys, more meat, less calcium and more vitamin C may have favoured the bioavailability of iron. CONCLUSIONS The discontinuation of the general iron fortification resulted in a 39% decrease in total iron intake and iron deficiency increased substantially in girls. However, in boys no change in iron deficiency was observed. Whether this was a result of changed bioavailability of dietary iron or simultaneous changes of non-dietary factors remains to be explored.

Abstract
OBJECTIVE The 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. DESIGN A 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. SETTING The present review considered adolescents attending high schools and recruited in hospitals or at home. SUBJECTS The target of the review was the healthy adolescent population in the age range 13-17 years. RESULTS Thirty-two eligible papers were included and analysed separately as 'original articles' (n 20) and 'reviews' (n 12). The majority (n 17) 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. CONCLUSIONS The 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.

Comparison of two dietary assessment methods by food consumption: results of the German National Nutrition Survey II. Eur J Nutr 2014; 54:343-54.

Abstract
PURPOSE To further characterise the performance of the diet history method and the 24-h recalls method, both in an updated version, a comparison was conducted. METHODS The National Nutrition Survey II, representative for Germany, assessed food consumption with both methods. The comparison was conducted in a sample of 9,968 participants aged 14-80. Besides calculating mean differences, statistical agreement measurements encompass Spearman and intraclass correlation coefficients, ranking participants in quartiles and the Bland-Altman method. RESULTS Mean consumption of 12 out of 18 food groups was higher assessed with the diet history method. Three of these 12 food groups had a medium to large effect size (e.g., raw vegetables) and seven showed at least a small strength while there was basically no difference for coffee/tea or ice cream. Intraclass correlations were strong only for beverages (>0.50) and revealed the least correlation for vegetables (<0.20). Quartile classification of participants exhibited more than two-thirds being ranked in the same or adjacent quartile assessed by both methods. For every food group, Bland-Altman plots showed that the agreement of both methods weakened with increasing consumption. CONCLUSIONS The cognitive effort essential for the diet history method to remember consumption of the past 4 weeks may be a source of inaccurateness, especially for inhomogeneous food groups. Additionally, social desirability gains significance. There is no assessment method without errors and attention to specific food groups is a critical issue with every method. Altogether, the 24-h recalls method applied in the presented study, offers advantages approximating food consumption as compared to the diet history method.

Abstract
OBJECTIVES Metabolic syndrome (MetS) is a disorder in which obesity, insulin resistance, high blood pressure and dyslipidemia coexist. This study assessed the prevalence of MetS and its associated factors in patients who underwent orthotopic liver transplantation (OLTx). METHODS Post-OLTx patients were assessed for the presence of MetS according to the diagnostic criteria proposed by the International Diabetes Federation (IDF) and National Heart, Lung, and Blood Institute/American Heart Association (NHLBI/AHA). Demographic, socioeconomic, lifestyle, clinical, anthropometric, and dietary variables were collected to identify predictors for MetS using logistic regression analysis. RESULTS Among the 148 patients assessed, the prevalence of MetS was 50% (IDF criteria) and 38.5% (NHLBI/AHA criteria). For both the IDF and the NHLBI/AHA classifications, the independent factors associated with MetS were older age, shorter time since transplantation, and history of excessive weight prior to OLTx. Other predictors for MetS by IDF criteria were alcohol abuse as the indication for OLTx, physical activity reduction as the cause of weight gain after transplantation, and calcium intake below recommended levels. The presence of MetS (NHLBI/AHA) was also associated with decreased intake of potassium, fiber, and folic acid. CONCLUSIONS MetS is highly prevalent among post-OLTx patients and it is predicted by older age, shorter time since transplantation, alcohol abuse as the cause of cirrhosis, excessive weight prior to OLTx, and some potentially modifiable factors such as physical activity reduction after OLTx and low intake of calcium, potassium, fiber, and folic acid.

Abstract
A qualitative evaluation of the diet of a probabilistic sample of 7-10 year old schoolchildren (n=1,232) from Florianópolis (southern Brazil) was carried out by analyzing compliance with recommendations from the Brazilian Food Guidelines. The strengths and limitations of the Previous Day Food Questionnaire (PDFQ) are also presented. Frequencies of intake were defined as how many times per day the food group was reported on the PDFQ. The percentages of schoolchildren who met the minimum recommendations and who ate foods that were not recommended in the guidelines were compared for boys versus girls, private versus public school and by family income level. Although most of the children complied with the guidelines regarding consumption of meat/fish, dry beans, sweets, and eating three meals and two snacks, only 6.5% of the children met the recommendations for cereals, and 15% for fruit and vegetables. The PDFQ was confirmed as a practical and cost-effective method for the evaluation of compliance with health promotion targets.

Abstract
Information of exposure factors used in quantitative risk assessments has previously been compiled and reported for U.S. and European populations. However, due to the advancement of science and knowledge, these reports are in continuous need of updating with new data. Equally important is the change over time of many exposure factors related to both physiological characteristics and human behavior. Body weight, skin surface, time use, and dietary habits are some of the most obvious examples covered here. A wealth of data is available from literature not primarily gathered for the purpose of risk assessment. Here we review a number of key exposure factors and compare these factors between northern Europe--here represented by Sweden--and the United States. Many previous compilations of exposure factor data focus on interindividual variability and variability between sexes and age groups, while uncertainty is mainly dealt with in a qualitative way. In this article variability is assessed along with uncertainty. As estimates of central tendency and interindividual variability, mean, standard deviation, skewness, kurtosis, and multiple percentiles were calculated, while uncertainty was characterized using 95% confidence intervals for these parameters. The presented statistics are appropriate for use in deterministic analyses using point estimates for each input parameter as well as in probabilistic assessments.

Abstract
OBJECTIVE To investigate if dietary energy density is associated with measures of dietary quality (food group, micronutrient and macronutrient intakes) in children and adolescents. SUBJECTS/METHODS In all, 551 children (mean age 9.6 years, 52% girls) and 569 adolescents (15.5 years, 55% girls), sampled from schools in Sweden, completed a single 24-h dietary recall. Dietary energy density (kJ/g) was calculated as the energy from all food consumed divided by the weight of all food consumed. Beverages were excluded from the calculation. Food and micronutrient intakes were adjusted for energy intake. A one-way analysis of variance (ANOVA) was used to test for differences in food group and nutrient intakes across age- and gender-specific tertiles of energy density. Discriminant analysis was used to confirm the groupings formed by tertiles. RESULTS Subjects with low-energy-density diets were significantly more likely to consume fruits, vegetables, pasta, rice, potatoes and cereals and less likely to consume sweetened drinks, sweets and chocolate. After energy adjustment, their intakes of many foods recommended in the Swedish food-based dietary guidelines were higher and intakes of nutrient-poor foods were lower. The macronutrient energy profile (% energy) of low-energy-density diets was closest to the recommended level. Low-energy-density diets contained greater amounts of most micronutrients. Discriminant analysis confirmed the existence of heterogeneous dietary patterns and the likelihood of correct classification by energy density in 65% of cases. CONCLUSIONS Lower dietary energy density is associated with better dietary quality in children and adolescents. Energy density has advantages over other whole diet analysis methods and may be suitable as a simple proxy of diet quality.

Abstract
O estudo objetivou conferir validade à terceira versão do Questionário Alimentar do Dia Anterior (QUADA-3) para escolares. O QUADA-3 é um instrumento estruturado com seis refeições e 21 alimentos. Participaram 164 escolares de 6 a 11 anos de idade, de uma escola pública de período integral, em 2007. A validade foi testada pela comparação entre os itens alimentares selecionados no questionário e a observação direta de alimentos consumidos em três refeições escolares do dia anterior (lanche da manhã, almoço, lanche da tarde). Análise de regressão logística multivariada foi conduzida para avaliar a discordância entre as respostas do questionário e o registro das observações. Os resultados indicaram alta sensibilidade e especificidade para a maioria dos itens alimentares. Em média, os valores de sensibilidade e especificidade foram de 70,2% e de 96,2%, respectivamente, para os 12 itens alimentares nas três refeições combinadas. Os escolares de 6 a 8 anos, quando comparados aos de 9 a 11 anos, apresentam maiores taxas de discordância de respostas entre o QUADA-3 e as observações. Os resultados indicaram que o QUADA-3 pode gerar dados válidos para avaliar o consumo alimentar do dia anterior em nível de grupo de escolares.
