Abstract Background Suboptimal diet is the leading cause of global morbidity and mortality. Addressing this problem requires context-specific solutions informed by context-specific data collected by context-specific tools. This study aimed to assess the relative validity of a newly developed brief dietary survey to estimate food intake and adherence to the Food Based Dietary Guidelines for Sri Lankans. Methods Between December 2018 and February 2019, we interviewed 94 Sri Lankan adults living in Colombo (Western Province), Kalutara (Western Province), and Trincomalee (Eastern Province). We assessed the relative validity of the Sri Lankan Brief Dietary Survey (SLBDS) with Wilcoxon rank-sum tests, Spearman’s Rho correlation coefficients, Bland–Altman plots, and Cohen’s kappa tests using a 24-h Dietary Recall (24DR) as reference. Results Ninety-four adults (40.7 years ±12.6; 66% female) completed both surveys during the same interview. With the exception of ‘Fish, pulses, meat and eggs’ food group median intake, which was underestimated by the SLBDS compared to the 24DR, there was no strong evidence of difference between median intakes reported by the two methods. Correlation coefficients were highest for ‘Milk and dairy products’ (0.84) at the food group level and for ‘dosa’, ‘hoppers’, ‘milk rice’, and ‘dried fish’ (1.00) among individual food and beverages. Visual exploration of Bland-Altman plots showed acceptable agreement between the SLBDS and 24DR, with the SLBDS tending to overestimate consumption as the number of servings of ‘Rice, bread, other cereals and yams’ and ‘Vegetables’ consumed increased and slightly underestimate consumption as the number of servings of ‘Fish, pulses, meat and eggs’, ‘Milk and dairy products’, and ‘Nuts’ increased. Kappa values ranged from from 0.59 (95% CI: 0.32–0.86) for ‘Vegetables’ to 0.81 (95% CI: 0.66–0.96) for ‘Fruit’ indicating a moderate to strong level of agreement. Conclusions Having been developed for and relatively validated with the study population in question, our study shows that the SLBDS can be used as a fit for purpose research tool. Additional research is needed to assess SLBDS test-retest reliability and to validate further the reporting of salt, oil, and coconut intake.

AbstractObjectiveTo assess the reproducibility and validity among adults in the Southern Cone of Latin America (Argentina, Chile and Uruguay) of a self-administered FFQ to be used in the CESCAS I Study, an ongoing observational prospective cohort study to detect and follow up CVD and their risk factors, as well as in other epidemiological studies.DesignRelative validity of the FFQ was evaluated by comparing nutrient and selected food group intakes with those from three 24 h recalls (24HR) administered over 6 months. The FFQ was administered at baseline (FFQ1) and again after 3 months (FFQ2).SettingPrimary-care centres in Argentina, Chile and Uruguay.SubjectsAdults (n 147) aged 21–74 years.ResultsReproducibility (FFQ1 v. FFQ2): the intra-class correlation coefficients for nutrients ranged from 0·52 (potassium) to 0·74 (fat). Validity (FFQ1 v. the average of three 24HR): the Pearson correlations for energy-adjusted nutrients ranged from 0·39 (thiamin and cholesterol) to 0·59 (carbohydrate). Joint classification: overall, 66 % of participants in the lowest 24HR quintile were in the lowest one or two FFQ1 quintiles, and 62 % of those in the highest 24HR quintile were in the highest one or two FFQ1 quintiles. On average, only 4 % were misclassified into extreme quintiles.ConclusionsThe FFQ version for the Southern Cone seems to present moderate to acceptable relative validity and reliability for its use in the CESCAS I Study to measure dietary exposure.

AbstractObjectiveTo evaluate the validity and reproducibility of a 122-item interviewer-administered quantitative FFQ developed to determine food and nutrient intakes of adults in Botswana.DesignRelative validity of the FFQ was evaluated by comparing nutrient and food group intakes against four non-consecutive 24 h recalls administered over 12 months. The FFQ was repeated after 1 year to assess reproducibility.SettingKanye, Botswana.SubjectsSeventy-nine adults aged 18–75 years.ResultsSpearman correlation coefficients for the validity of energy-adjusted nutrients ranged from 0·42 (carbohydrate) to 0·49 (protein) for macronutrients and from 0·23 (Fe) to 0·44 (PUFA) for micronutrients. Exact agreement of quartile distribution for nutrients between the FFQ and recalls ranged from 27 % to 72 %. Weighted kappa values were lowest for retinol (0·13), Fe (0·22) and β-carotene (0·25) and ranged from 0·33 (SFA) to 0·59 (folate) for other nutrients (energy, carbohydrate, protein, fat, Ca and vitamin E). Spearman correlation coefficients between the recalls and FFQ for food groups ranged from 0·18 (dark green leafy and yellow vegetables) to 0·58 (poultry). Reproducibility correlation coefficients (energy-adjusted) varied between 0·39 for retinol and 0·66 for vitamin E, with most values falling between 0·50 and 0·60.ConclusionsThe FFQ had good relative validity for estimating habitual food group and nutrient intakes, but was poor for some micronutrients (Fe, retinol and β-carotene) and foods (fruits and dark green leafy vegetables).

AbstractObjectiveTo examine the relative validity of an FFQ based on parental report for pre-school children in the mother–child ‘Rhea’ birth cohort.DesignThe children’s mothers completed an FFQ that referred to the children’s dietary intake for the previous year by telephone interview. Mothers completed also three food records, two on weekdays and one on a weekend day. Spearman correlation coefficients were calculated for the energy-adjusted values. Weighted kappa statistics (κw) and the Bland–Altman technique were used to test the degree of agreement between the two dietary methods.SettingHeraklion, Crete, Greece, 2011–2012.SubjectsA total of ninety-nine mothers (corresponding to fifty-one boys and forty-eight girls) participated in the validation study.ResultsThe mean and median values of all food group and nutrient intakes did not differ significantly between the two dietary methods. Overall, fair agreement was observed between the FFQ and the food records for ranking participants based on their intake, with κw ranging from 0·21 to 0·40 for most foods and nutrients. On average, 88 % of participants were classified into the same or adjacent tertiles for nutrient and food group intakes by both dietary methods. The degree of agreement was also confirmed by the visual examination of the Bland–Altman plots.ConclusionsThe study indicates that the Rhea 4 years FFQ is a relatively accurate tool for assessing habitual food group and nutrient intakes among pre-school children in Crete, Greece.

AbstractObjectiveThe main aim of the present study was to identify food consumption in Sri Lankan adults based on serving characteristics.DesignCross-sectional study. Fruits, vegetables, starch, meat, pulses, dairy products and added sugars in the diet were assessed with portion sizes estimated using standard methods.SettingTwelve randomly selected clusters from the Sri Lanka Diabetes and Cardiovascular Study.SubjectsSix hundred non-institutionalized adults.ResultsThe daily intake of fruit (0·43), vegetable (1·73) and dairy (0·39) portions were well below national recommendations. Only 3·5 % of adults consumed the recommended 5 portions of fruits and vegetables/d; over a third of the population consumed no dairy products and fewer than 1 % of adults consumed 2 portions/d. In contrast, Sri Lankan adults consumed over 14 portions of starch and 3·5 portions of added sugars daily. Almost 70 % of those studied exceeded the upper limit of the recommendations for starch intake. The total daily number of meat and pulse portions was 2·78.ConclusionsDietary guidelines emphasize the importance of a balanced and varied diet; however, a substantial proportion of the Sri Lankan population studied failed to achieve such a recommendation. Nutrition-related diseases in the country may be closely correlated with unhealthy eating habits.

The paper discusses the impact of the competition level on the sustainable development of a regional market in order to manage competitive and industrial policies. The authors proposed to calculate the impact of the competition level on the economic affordability of food products to the population according to the Herfindahl-Hirschman index. For this purpose, the paper determines the correlation coefficients between the Herfindahl-Hirschman index and indicators affecting the economic availability of milk for the population of the Russian Federation. According to the data for 2010-2016, the market of milk and dairy products of the region of the Russian Federation (by the example of the Republic of Tatarstan) was analyzed. On the basis of the approach proposed, a regression model was obtained depending on the level of competition on the share of population expenditures on milk and dairy products. The proposed tool can be applied in any territory, what determines its universality.

Abstract Background Sri Lanka faces the double burden of over- and undernutrition. To tackle this dual challenge, double duty interventions that improve the quality of the Sri Lankan diet in line with national dietary guidelines have been suggested. The success of these interventions depends upon an understanding of the context-specific factors that impact their uptake within the population. The purpose of this study was threefold: explore household responsibility for food-related labour; understand food decision-making influences; and investigate consumption hierarchies that might impact the distribution of intervention benefits. Methods We conducted face-to-face semi-structured interviews with 93 Sri Lankan adults residing in urban Colombo (n = 56), and urban and rural sectors in Kalutara (n = 29) and Trincomalee (n = 8). Interview data were analysed thematically. Results Findings from this study suggest that women in Sri Lanka continue to shoulder the burden of food-related labour disproportionately to men but that this responsibility is not always a proxy for dietary decision-making power. While men are often absent from the kitchen, their role in food purchasing and payment is prominent in many households. Despite these observed gender differences in food labour and provisioning, “traditional” age- and gender-based consumption hierarchies with negative nutrition consequences for women and children are not common, indicating that Sri Lankan ‘table culture’ may be changing. Conclusion Dietary interventions with the aim of influencing day-to-day practice should be developed with an awareness of who is responsible for, who is able to perform, and who influences targeted behaviours.

Objectives: To describe the adherence of the children to the Swiss Society for Nutrition (SSN) dietary guidelines, assess determinants of adherence, and compare these findings with a previous study in the same population.Methods: Data from 312 children ages 5–12 were collected through a survey and a 2-day food record. The associations of children- and parent-related factors with adherence of the children to guidelines were assessed by logistic regression analyses.Results: SSN guidelines were not met for any food category, although there were improvements: vegetables (4.5% in this study vs. 0% in the previous study), sweets, snacks, and soft drinks (SSD) (12.5 vs. 9.5%), and fruit (45.5 vs. 10.4%). Higher Body Mass Index (BMI) in children was associated with higher adherence to guidelines for protein intake. Higher parental BMI was associated with higher adherence to vegetables. Parental lower educational level was associated with higher adherence for cereal.Conclusion: Despite improvements since the last eating behavior assessment in this population, children consume too little fruit, vegetables, cereal, and milk and dairy products, and too much SSD and proteins. Further efforts are needed to promote healthy eating to children and achieve adherence to guidelines.

This work describes a rapid, selective, and sensitive method by using liquid chromatography-tandem mass spectrometry (LC-MS/MS) to detect melamine (MEL) in milk and dairy products. The optimal conditions of liquid chromatographic separation extraction and mass spectroscopy of MEL have also been examined. The linear range for analyte detected by the method was 0.5÷100.0 ng/mL, with correlation coefficients was 0.999.  Mean recoveries of the method in the real samples at three spike levels (low, medium, and high) were within the range of 98.5% ÷102.5% (n =7). LOD, LOQ values of the method were 10 and 30 ng/mL, respectively. The influence of the matrix effect on the accuracy, repeatability, and recovery of the process was insignificant. The proposed method was used to quantify the content of this compound in various real samples, which were collected in Ho Chi Minh City-Vietnam in 2020.

AbstractObjectiveTo assess the relative validity of a semi-quantitative, web-based FFQ completed by female pregnancy planners in the Danish ‘Snart Forældre’ study.DesignWe validated a web-based FFQ based on the FFQ used in the Danish National Birth Cohort against a 4 d food diary (FD) and assessed the relative validity of intakes of foods and nutrients. We compared means and medians of intakes, and calculated Pearson correlation coefficients and de-attenuated coefficients to assess agreement between the two methods. We also calculated the proportion correctly classified based on the same or adjacent quintile of intake and the proportion of grossly misclassified (extreme quintiles).SettingParticipants (n 128) in the ‘Snart Forældre’ study who had completed the web-based FFQ were invited to participate in the validation study.SubjectsParticipants in the ‘Snart Forældre’ study, in total ninety-seven women aged 20–42 years.ResultsReported intakes of dairy products, vegetables and potatoes were higher in the FFQ compared with the FD, whereas reported intakes of fruit, meat, sugar and beverages were lower in the FFQ than in the FD. Overall the de-attenuated correlation coefficients were acceptable, ranging from 0·33 for energy to 0·93 for vitamin D. The majority of the women were classified in the same or adjacent quintile and few women were misclassified (extreme quintiles).ConclusionThe web-based FFQ performs well for ranking women of reproductive age according to high or low intake of foods and nutrients and, thus, provides a solid basis for investigating associations between diet and fertility.

AbstractObjectiveTo compare the relative validity of food group intakes derived from a comprehensive self-administered diet history questionnaire (DHQ) and a brief-type DHQ (BDHQ) developed for the assessment of Japanese diets during the previous month using semi-weighed dietary records (DR) as a reference method.DesignBetween November 2002 and September 2003, a 4 d DR (covering four non-consecutive days), a DHQ (150-item semi-quantitative questionnaire) and a BDHQ (fifty-eight-item fixed-portion-type questionnaire) were completed four times (once per season) at 3-month intervals.SettingThree areas in Japan: Osaka, Nagano and Tottori.SubjectsNinety-two Japanese women aged 31–69 years and ninety-two Japanese men aged 32–76 years.ResultsMedian food group intakes were estimated well for approximately half of the food groups. No statistically significant differences were noted between a 16 d DR and the first DHQ (DHQ1) or between the DR and the first BDHQ (BDHQ1) in fifteen (44 %) and fifteen (52 %) food items for women and in fourteen (41 %) and sixteen (55 %) food items for men, respectively, indicating that both questionnaires estimated median values reasonably well. Median Spearman's correlation coefficients with the DR were 0·43 (range: −0·09 to 0·77) for DHQ1 and 0·44 (range: 0·14 to 0·82) for BDHQ1 in women, with respective values of 0·44 (range: 0·08 to 0·87) and 0·48 (range: 0·22 to 0·83) in men, indicating reasonable ranking ability. Similar results were observed for mean values of the four DHQ and BDHQ.ConclusionsIn terms of food intake estimates, both the DHQ and the BDHQ showed reasonable validity.
