AbstractObjective:For proper interpretation of results from epidemiological studies that use food-frequency questionnaires (FFQs), it is necessary to know the relationship between reported intakes from the FFQ and true usual intake. In this paper, we report a calibration study conducted to investigate the performance of the FFQ used in a cohort study, the Canadian Study of Diet, Lifestyle and Health.Methods:Over a 1-year period, 151 men and 159 women completed a full set of questionnaires including a self-administered baseline FFQ, three 24-hour diet recalls administered by telephone, and a second FFQ self-administered subsequently. The association between the nutrient estimates derived from the FFQs and the diet recalls was evaluated by calculating deattenuated Pearson's correlation coefficients.Results:The FFQs estimated mean daily nutrient intakes higher than the diet recalls. When the log-transformed and energy-adjusted nutrient intakes from the average of three 24-hour recalls were compared against the baseline FFQ, the following deattenuated correlations were obtained in men and women, respectively: total energy 0.44 and 0.32, total fat 0.64 and 0.68, saturated fat 0.68 and 0.70, dietary fibre 0.65 and 0.44, vitamin E 0.32 and 0.37, vitamin C 0.40 and 0.37, β-carotene 0.34 and 0.29, alcohol 0.74 and 0.67, caffeine 0.81 and 0.76, with a median correlation of 0.49 and 0.53. Correlations between the second FFQ and diet recalls were similar. The correlations between the two FFQs as a test of reliability had a median value 0.64 for men and 0.63 for women for selected nutrients.Conclusions:The study suggests that the FFQ method gives acceptable levels of nutrients or food component estimates, as assessed by this calibration study against diet recalls, when limited to energy-adjusted and deattenuated values.

The Relationship

The present paper examines the relationship of nutritional status to further life expectancy and health status in the Japanese elderly based on 3 epidemiological studies. Nutrient intakes in 94 Japanese centenarians investigated between 1972 and 1973 showed a higher proportion of animal protein to total proteins than in contemporary average Japanese. High intakes of milk and fats and oils had favorable effects on 10-year (1976–1986) survivorship in 422 urban residents aged 69–71. The survivors revealed a longitudinal increase in intakes of animal foods such as eggs, milk, fish and meat over the 10 years. Nutrient intakes were compared, based on 24-hour dietary records, between a sample from Okinawa Prefecture where life expectancies at birth and 65 were the longest in Japan, and a sample from Akita Prefecture where the life expectancies were much shorter. Intakes of Ca, Fe, vitamins A, B1, B2, C, and the proportion of energy from proteins and fats were significantly higher in the former than in the latter. Intakes of carbohydrates and NaCl were lower.

We constructed a food-based diet quality score (DQS) and examined its association with obesity measures, eating styles and nutrient intakes. Participants were 3592 individuals (764 dizygotic [DZ] and 430 monozygotic [MZ] twin pairs) from the FinnTwin16 study. The DQS (0–12 points) was constructed from a short 14 item food frequency questionnaire. Anthropometric measures and eating styles were self-reported. Nutrient intakes were calculated from food diaries completed in a subsample of 249 individuals (45 same-sex DZ and 60 MZ twin pairs). Twins were analyzed both as individuals and as twin pairs. The DQS was inversely associated with body mass index (β = −0.12, per one-unit increase in DQS, p < 0.001), waist circumference (β = −0.34, p < 0.001), obesity (odds ratio [OR]: 0.95, p = 0.004) and abdominal obesity (OR: 0.88, p < 0.001), independent of sex, age, physical activity and education. A higher DQS was associated with health-conscious eating, having breakfast, less snacking, fewer evening meals, and a higher frequency and regularity of eating. The DQS was positively correlated with the intakes of protein, fiber and magnesium and negatively correlated with the intakes of total fat, saturated fat and sucrose. Within twin pairs, most of the associations between the DQS with eating styles and some nutrients remained, but the DQS was not associated with obesity measures within twin pairs. The DQS is an easy-to-use tool for ranking adults according to diet quality and shows an association with obesity measures, eating styles and key nutrients in the expected direction.

AbstractStrong evidence exists linking poor diet to increased risk of overweight, obesity and non-communicable diseases. Reformulation initiatives, whereby the food industry gradually reduces energy, sodium, sugar, fat and saturated fat content of their products, are identified as important strategies to improve dietary intakes. The analysis aimed to examine the impact of voluntary reformulation, changes to products on the market and changes in consumer preferences on dietary intakes in Ireland from 2005 to 2017. Data on composition and volume sales (kg/ year) of products available on the market in 2005 and 2017 were collected from 15 Food Drink Ireland (FDI) member companies via online templates. These products were assigned to appropriate food and beverage groups identified in four Irish University Nutrition Alliance (IUNA) surveys of preschool children (1–4 years), children (5–12 years), teenagers (13–17 years) and adults (18–90 years). Assignment of FDI products to IUNA foods and beverages was carried out using weighted distributions for a given group of foods. The weightings were taken from the sales volumes of similar products relative to one another in a given category in a given year. Monte Carlo simulations were used to run the IUNA survey consumption data with both sets of weighted composition data from 2005 and 2017. The Creme Global intake model was used to estimate daily energy and nutrient intakes for all four populations during 2005 and 2017. The Wilcoxon-signed rank test was used to test for differences between the two years. Changes in both the products available on the market and market share of these products were observed from 2005 to 2017. The nutrient with the greatest intake reduction between the two years for all ages was sugar. Children and teens were the most affected, where total sugar intakes reduced by 3.2g/d and 2.7g/d, respectively. This reduction was primarily driven by the beverage category. There were modest saturated fat intake reductions observed for teens and adults (0.2g/d and 0.5g/d, respectively). Energy, total fat and sodium intakes for all ages remained relatively stable between the two years. This analysis highlights the impact of not only food industry efforts but also consumer choices on nutrient intakes in Ireland. It is worth noting that the data collected predates the sugar tax on sugar-sweetened beverages in Ireland. Reductions in sugar intakes were not compensated by total fat or energy increases.

The Relationship

AbstractThe aims of the present study were to investigate the shape and strength of the force-velocity relationships observed in different functional movement tests and explore the parameters depicting force, velocity and power producing capacities of the tested muscles. Twelve subjects were tested on maximum performance in vertical jumps, cycling, bench press throws, and bench pulls performed against different loads. Thereafter, both the averaged and maximum force and velocity variables recorded from individual trials were used for force–velocity relationship modeling. The observed individual force-velocity relationships were exceptionally strong (median correlation coefficients ranged from r = 0.930 to r = 0.995) and approximately linear independently of the test and variable type. Most of the relationship parameters observed from the averaged and maximum force and velocity variable types were strongly related in all tests (r = 0.789-0.991), except for those in vertical jumps (r = 0.485-0.930). However, the generalizability of the force-velocity relationship parameters depicting maximum force, velocity and power of the tested muscles across different tests was inconsistent and on average moderate. We concluded that the linear force-velocity relationship model based on either maximum or averaged force-velocity data could provide the outcomes depicting force, velocity and power generating capacity of the tested muscles, although such outcomes can only be partially generalized across different muscles.

AbstractA standardised, national, 160-item FFQ, the FFQ-NL 1.0, was recently developed for Dutch epidemiological studies. The objective was to validate the FFQ-NL 1.0 against multiple 24-h recalls (24hR) and recovery and concentration biomarkers. The FFQ-NL 1.0 was filled out by 383 participants (25–69 years) from the Nutrition Questionnaires plus study. For each participant, one to two urinary and blood samples and one to five (mean 2·7) telephone-based 24hR were available. Group-level bias, correlation coefficients, attenuation factors, de-attenuated correlation coefficients and ranking agreement were assessed. Compared with the 24hR, the FFQ-NL 1.0 estimated the intake of energy and macronutrients well. However, it underestimated intakes of SFA andtrans-fatty acids and alcohol and overestimated intakes of most vitamins by >5 %. The median correlation coefficient was 0·39 for energy and macronutrients, 0·30 for micronutrients and 0·30 for food groups. The FFQ underestimated protein intake by an average of 16 % and K by 5 %, relative to their urinary recovery biomarkers. Attenuation factors were 0·44 and 0·46 for protein and K, respectively. Correlation coefficients were 0·43–0·47 between (fatty) fish intake and plasma EPA and DHA and 0·24–0·43 between fruit and vegetable intakes and plasma carotenoids. In conclusion, the overall validity of the newly developed FFQ-NL 1.0 was acceptable to good. The FFQ-NL 1.0 is well suited for future use within Dutch cohort studies among adults.

AbstractObjectiveFFQ are commonly used to rank individuals by their food and nutrient intakes in large epidemiological studies. The purpose of the present study was to develop and validate an FFQ to rank individuals participating in an ongoing Prospective Urban and Rural Epidemiological (PURE) study in Chile.DesignAn FFQ and four 24 h dietary recalls were completed over 1 year. Pearson correlation coefficients, energy-adjusted and de-attenuated correlations and weighted kappa were computed between the dietary recalls and the FFQ. The level of agreement between the two dietary assessment methods was evaluated by Bland–Altman analysis.SettingTemuco, Chile.SubjectsOverall, 166 women and men enrolled in the present study. One hundred men and women participated in FFQ development and sixty-six individuals participated in FFQ validation.ResultsThe FFQ consisted of 109 food items. For nutrients, the crude correlation coefficients between the dietary recalls and FFQ varied from 0·14 (protein) to 0·44 (fat). Energy adjustment and de-attenuation improved correlation coefficients and almost all correlation coefficients exceeded 0·40. Similar correlation coefficients were observed for food groups; the highest de-attenuated energy-adjusted correlation coefficient was found for margarine and butter (0·75) and the lowest for potatoes (0·12).ConclusionsThe FFQ showed moderate to high agreement for most nutrients and food groups, and can be used to rank individuals based on energy, nutrient and food intakes. The validation study was conducted in a unique setting and indicated that the tool is valid for use by adults in Chile.

AbstractObjectives:The purpose of this paper is to present longitudinal data on nutrient intakes of youth with emphases on differences by sex and race/ethnicity. Nutrients selected for examination are those implicated in chronic disease.Design:24-hour dietary recalls were collected from a cohort of third, fifth and eighth graders (n=1874).Setting and subjects:The sample is drawn from the Child and Adolescent Trial for Cardiovascular Health and includes students from California, Louisiana, Minnesota and Texas.Results:Across the total sample, nutrient intakes met recommended levels except that total fat, saturated fat and sodium consistently exceeded recommendations and calcium and iron intake of girls consistently fell short of recommended levels. Nutrient consumption between third and eighth grade differed by sex and race/ethnicity for a number of nutrients. In particular, females' intake of energy from total fat, calcium, iron, folic acid, vitamin A and vitamin D decreased over time relative to males' intakes, controlling for overall energy intake. Compared with the other ethnic/racial groups, African-American students increased their intake of energy from total fat and saturated fat over time.Conclusions:Our results suggest that the diets of youth change over time, and negative trends are more common in females than in males and in African-American and Hispanics compared with Caucasian students. Nutrition education and intervention are needed throughout childhood and adolescence with an emphasis on choosing healthful foods. In addition, greater attention to differential opportunities and reinforcements for females and males, and Caucasian, Hispanic and African-American students is warranted.

AbstractIntroductionMeat is a nutrient-dense food that plays a central role in the diets of many children globally, contributing significantly to intakes of energy, protein and a number of essential micronutrients. However, nutritive quality is variable across meat types and cuts, and dietary guidelines across Europe typically encourage the consumption of lean meats whilst limiting the consumption of processed meats. The current work aimed to estimate intakes of unprocessed beef and lamb and their contribution to nutrient intakes in Irish children and teenagers.MethodsAnalyses were based on data from the Irish National Children's Food Survey (NCFS) (2003–2004; 5–12 years; n 594) and National Teens’ Food Survey (NTFS) (2005–2006; 13–17 years; n 441) (www.iuna.net). Both surveys used a 7-day weighed (NCFS) or semi-weighed (NTFS) food record to collect dietary intake data from nationally representative samples of Irish children. Dietary intake data were converted to nutrient data using WISP©, based on UK and Irish food composition tables. Unprocessed beef and lamb was defined as beef or lamb that had not undergone any preserving process other than chilling, freezing or salting, and included beef or lamb dishes that were wrapped in a controlled atmosphere. Meat intakes from composite dishes (e.g. beef lasagne) were estimated following disaggregation of the non-meat components. Statistical analyses were carried out using SPSS© v23.0.ResultsUnprocessed beef was consumed by 79% of children and 83% of teenagers, while unprocessed lamb was consumed by 19% of children and 20% of teenagers. Mean daily intakes of unprocessed beef were 21 g and 34 g in children and teenagers (consumers only), while mean daily intakes of unprocessed lamb were 14 g and 23 g. Unprocessed beef and lamb contributed 5–6% to mean daily energy intakes and contributed the following proportions to daily nutrient intakes in children and teenagers, respectively: protein (11%, 15%), total fat (7%, 9%), saturated fat (7%, 10%), monounsaturated fat (9%, 11%), iron (7%, 10%), zinc (18%, 23%), vitamin A (7%, 7%), vitamin D (12%, 16%), total niacin (9%, 13%), vitamin B6 (6%, 9%), vitamin B12 (15%, 22%), sodium (6%, 7%).DiscussionUnprocessed beef and lamb are valuable sources of nutrients for Irish children and teenagers. Relative to their energy contribution, they contribute higher proportions of a number of important nutrients, such as protein, zinc, vitamin D, vitamin B12 and total niacin, while contributing relatively small proportions of total fat, saturated fat and sodium. This research was funded by Meat Technology Ireland.

AbstractObjectiveLarge portion sizes in restaurants have been identified as a public health risk. The purpose of the present study was to determine whether customers in two different food-service operator segments (non-commercial worksite cafeteria and commercial upscale restaurant) would select reduced-portion menu items and the impact of selecting reduced-portion menu items on energy and nutrient intakes and plate waste.DesignConsumption and plate waste data were collected for 5 weeks before and 7 weeks after introduction of five reduced-size entrées in a worksite lunch cafeteria and for 3 weeks before and 4 weeks after introduction of five reduced-size dinner entrées in a restaurant setting. Full-size entrées were available throughout the entire study periods.SettingA worksite cafeteria and a commercial upscale restaurant in a large US Midwestern metropolitan area.SubjectsAdult worksite employees and restaurant patrons.ResultsReduced-size entrées accounted for 5·3–12·8 % and 18·8–31·3 % of total entrées selected in the worksite and restaurant settings, respectively. Food waste, energy intake and intakes of total fat, saturated fat, cholesterol, Na, fibre, Ca, K and Fe were significantly lower when both full- and reduced-size entrées were served in the worksite setting and in the restaurant setting compared with when only full-size entrées were served.ConclusionsA relatively small proportion of reduced-size entrées were selected but still resulted in reductions in overall energy and nutrient intakes. These outcomes could serve as the foundation for future studies to determine strategies to enhance acceptance of reduced-portion menu items in restaurant settings.

Background and Aims: Food frequency questionnaires (FFQ) have been widely used in epidemiologic studies since 1990s, but instruments need to be validated. The aim of this work was to create and assess the validity and reproducibility of an interview administered FFQ to be used in a Mexican women’s bone health cohort study, located in Monterrey city, Mexico. Methods: Validation of FFQ formed by 11 food groups and 136 food and beverage items was performed on 40–65-year-old Mexican women (n = 200) by applying 2 FFQ (test method) and six 24-h dietary recalls (24hR, reference method; 1 per season on weekdays and 2 on weekends). Pearson correlation coefficient was calculated of both logs, transformed intakes and energy-adjusted nutrient intakes based on the residual method, and intraclass correlation coefficients were calculated. Results: The relative validity of FFQ against the average of six 24hR for intakes of energy, macronutrients, cholesterol, water, vitamins and minerals required for bone metabolism such as vitamin D, calcium, magnesium, phosphorus were obtained. Pearson coefficients of correlation show significance (p < 0.05) for the validity, 0.244–0.820 and 0.258–0.794, for energy-unadjusted and adjusted data, respectively. Reproducibility coefficients range 0.186–0.810 for energy-unadjusted data and 0.174–0.597 for energy-adjusted data. Most nutrients showed lower than 5% of misclassification. Conclusion: The designed 136-item FFQ shows acceptable validity and reproducibility, and it is useful to be applied on 40–65-year-old Mexican women for the estimation of nutrient intakes in epidemiological studies.
