AbstractObjectiveThe aim of the present study was to assess the concurrent and construct validity of two diet-quality indices, a modified Mediterranean diet score (mMDS) and a Mediterranean-like diet score (MLDS) additionally incorporating unhealthy food choices, as determined by an FFQ.DesignA validation study assessing FFQ intake estimates compared with ten or more unannounced 24 h recalls. Pearson's correlation coefficients, intraclass correlation coefficients (ICC), Bland–Altman plots and the limits of agreement method were used to assess the between-method agreement of scores. Construct validity was shown using associations between nutrient intakes derived from multiple 24 h recalls and the mMDS and MLDS derived from the FFQ.SettingGerona, Spain.SubjectsA total of 107 consecutively selected participants from a population-based cross-sectional survey.ResultsPearson's correlations for the energy-adjusted mMDS and MLDS compared with multiple recalls were 0·48 and 0·62, respectively. The average FFQ energy-adjusted mMDS and MLDS were 102 % and 98 % of the recall-based mMDS and MLDS estimates, respectively. The FFQ under- and overestimated dietary recall estimates of the energy-adjusted MLDS by 28 % and 25 %, respectively, with slightly wider boundaries for the mMDS (31 % and 34 %). The ICC, which assesses absolute agreement, was similar to Pearson's correlations (mMDS = 0·48 and MLDS = 0·61). The mean differences between methods were similar across the range of average ratings for both scores, indicating the absence of bias. The FFQ-derived mMDS and MLDS correlated in the anticipated directions with intakes of eleven (73·3 %) and thirteen of fifteen nutrients (86·7 %), respectively.ConclusionsThe FFQ provides valid estimates of diet quality as assessed by the mMDS and MLDS.

AbstractObjectiveAn urgent need in dietary assessment is the development of short tools that provide valid assessments of dietary quality for use in time-limited settings. The present study assessed concurrent and construct validity of the short Diet Quality Screener (sDQS) and brief Mediterranean Diet Screener (bMDSC) questionnaires.DesignRelative validity was measured by comparing three dietary quality indices – the Diet Quality Index (DQI), the modified Mediterranean Diet Score (mMDS) and the Antioxidant Score (ANTOX-S) – derived from the two questionnaires with those from multiple 24 h recalls over 12 months. Construct validity was demonstrated by correlations between average nutrient intake recorded on multiple 24 h recalls and the DQI, mMDS and ANTOX-S derived by the short screeners.SettingBoth short questionnaires were administered to 102 participants recruited from a population-based survey in Spain.ResultsDQI, mMDS and ANTOX-S correlated (P < 0·001) with the corresponding 24 h recall indices (r = 0·61, 0·40 and 0·45, respectively). Limits of agreement lay between 96 and 126 %, 59 and 144 % and 61 and 118 % for the DQI, ANTOX-S and mMDS, respectively. Dietary intakes of fibre, vitamin C, vitamin E, Mg and K reported on the 24 h recalls were positively associated (P < 0·04) with the DQI, mMDS and ANTOX-S indices.ConclusionsThe sDQS and bMDSC provide reasonable approximations to food-based dietary indices and accurately situate subjects within the indices constructed for the present validation study.

AbstractObjectivesEvidence of the effects of soft drinks consumption on BMI and lifestyle in adult populations is mixed and quite limited. The aim of the present study was to determine the association of soft drinks consumption with BMI and lifestyle in a representative Mediterranean population.DesignTwo independent, population-based, cross-sectional (2000 and 2005) studies. Dietary intake was assessed using a validated FFQ. Weight and height were measured.SettingGirona, Spain.SubjectsRandom sample of the 35- to 74-year-old population (3910 men and 4285 women).ResultsLess than half (41·7 %) of the population consumed soft drinks; the mean consumption was 36·2 ml/d. The prevalence of sedentary lifestyle increased with the frequency of soft drinks consumption (P = 0·025). Daily soft drinks consumption significantly increased the risk of low adherence to the Mediterranean diet (OR = 0·57, 95 % CI 0·44, 0·74 v. top tertile of Mediterranean diet score). Multiple linear regression analyses, controlled for potential confounders, revealed that an increment in soft drinks consumption of 100 ml was associated with a 0·21 kg/m2 increase in BMI (P = 0·001). Only implausibly low reports of energy consumption showed a null association between soft drinks consumption and BMI.ConclusionsSoft drinks consumption was not embedded in a healthy diet context and was positively associated with BMI and sedentary lifestyle in this Mediterranean population.

AbstractObjectiveTo assess salt intake and its dietary sources using biochemical and self-report methods and to characterize salt intake according to sociodemographic and disease-related variables in a sample of the Brazilian population.DesignPopulation-based cross-sectional survey.SettingSalt intake was assessed by biochemical (24 h urinary Na excretion) and self-report methods (sodium FFQ, 24 h dietary recall, seasoned-salt questionnaire, discretionary-salt questionnaire and total reported salt intake).ParticipantsAdults and older people (n 517) aged 20–80 years, living in Artur Nogueira, São Paulo, Brazil.ResultsMean salt intake based on 24 h urinary Na excretion and total reported salt intake was 10·5 and 11·0 g/d, respectively; both measures were significantly correlated. Discretionary salt and seasoned salt were the most important sources of salt intake (68·2 %). Men in the study consumed more salt than women as estimated by 24 h urinary Na excretion (11·7 v. 9·6 g salt/d; P<0·0001). Participants known to be hypertensive added more salt to their meals but consumed less salty ultra-processed foods. Waist circumference in both sexes and BMI were positively correlated with salt intake estimated by 24 h urinary Na excretion. In addition, regression analysis revealed that being a young male or having a high waist circumference was a predictor of higher salt intake.ConclusionsSalt intake in this population was well above the recommended amount. The main source of salt intake came from salt added during cooking. Salt intake varied according to sex and waist circumference.

The present study aims at describing the sampling plan, operational aspects and strategies used to optimize the field work of a cross-sectional, population-based study conducted in a southern capital of Brazil. For this purpose, the sample design, data collection instrument, selection of interviewers, pilot study, data collection, field logistics, quality control, consistency control, costs, and divulgation of results are herein described. The study's response rate was 85.3%. We found that the comparison of frequency measurements with and without self-assessment had no significant impact on the estimates, and that the design effect, estimated at 2, was sufficient for most calculations. The reproducibility of the questionnaire was satisfactory, with Kappa values and intraclass correlation coefficients ranging from 0.6 to 0.9. The strategies used to overcome operational problems, such as counting of households, use of maps, questionnaire structuring, rigorous organization of the field work and monitoring of the estimates were fundamental in conducting the study.

Abstract Background/objectives The 2020 global coronavirus pandemic is characterized by increased anxiety. Anxiety has been associated with poor diet quality and weight gain, which may lead to obesity, a risk factor for adverse COVID-19 outcomes. The present study was designed to examine associations between diet quality and anxiety levels during the COVID-19 pandemic. Subjects/methods This cross-sectional, international online study was conducted between March 30 and April 25, 2020 and available in seven languages: Arabic (7.6%), English (43.7%), French (0.8%), Hebrew (42.1%), Italian (3%), Russian (1.1%), and Spanish (1.6%). Diet quality was assessed using the Mediterranean Diet Score (possible range: 0–17 points) and anxiety scored using the General Anxiety Disorder 7-point scale (GAD-7). The Google Survey platform was used to conduct the survey. Results A total of 3797 persons were included in the present analysis. More than 75% of respondents were female; most completed the survey in English or Hebrew. Median age was 31 (IQ = 18) years. Almost 60% indicated that their pre-pandemic diet was healthier than their current diet. The median Mediterranean diet score was 9 (IQ = 3). The majority (54%) of participants reported at least mild anxiety, while 25% reported moderate anxiety or more severe. In a logistic regression model of at least moderate anxiety, Mediterranean diet score (OR 0.92, 95% CI 0.89–0.95, p < 0.0001) reduced odds of elevated anxiety, even after controlling for age, sex and other variables. Conclusions Though causality cannot be inferred, associations between diet quality and anxiety might suggest public health interventions including diet and stress control during future mass lockdowns.

The St George's Respiratory Questionnaire (SGRQ) has been used to measure health-related quality of life (HRQoL) in patients with idiopathic pulmonary fibrosis (IPF).This analysis evaluated the psychometric properties of the SGRQ using data from 428 patients with IPF who participated in a 12-month, randomised, placebo-controlled phase II trial of nintedanib.Internal consistency (Cronbach's α) was 0.91 for SGRQ total and >0.70 for domain scores. Test–retest reliability (intraclass correlation coefficients) was 0.77, 0.77, 0.69 and 0.66 for SGRQ total, activity, impact and symptoms scores, respectively. Construct validity of SGRQ total and domain scores was supported by weak to moderate cross-sectional correlations with the Medical Research Council dyspnoea scale (0.32–0.55), 6-min walk test distance (−0.25– −0.34), percentage predicted forced vital capacity (−0.11– −0.15) and measures of gas exchange (−0.26–0.03). There was some evidence that the SGRQ total score was sensitive to detecting change.The reliability, construct validity and responsiveness of the SGRQ in patients with IPF suggest that this is an acceptable measure of HRQoL in patients with IPF.

This study aimed to assess diet quality score (DQS), considering healthy and unhealthy foods and nutrients, and diet diversity score (DDS) as indicators of risk of noncommunicable diseases in eight Latin American countries, and to verify the possible differences considering country, sex, age, socioeconomic, and nutritional status. A multicenter household population-based cross-sectional survey was conducted with 9218 individuals (age range 15–65 years). Sociodemographic and anthropometric data were collected. Dietary intake was measured using two non-consecutive 24-h recalls and diet quality and diversity were assessed. In the whole sample, scores were observed from 63.0% ± 9.3% to total DQS, 65.0% ± 13.6% to healthy dietary items and 60.2% ± 13.6% to unhealthy items, and 5.6 ± 1.1 out of 9 points to DDS. Women presented lower DDS compared to men (5.5 ± 1.1 vs. 5.6 ± 1.1, p < 0.001). Healthy DQS was higher as the socio-economic level increased, and unhealthy DQS was the opposite (p < 0.05). Total DQS was significantly lower only at the low socio-economic level (p < 0.05). Chile and Venezuela showed the lowest healthy (62.2 ± 15.2 and 61.9 ± 11.7, p < 0.05) and total DQS (61.4 ± 10.3, 61.2 ± 8.7, p < 0.05). No effects were observed when considering the age and anthropometric measurements. Promoting consumption of a diverse and high-quality diet is an essential challenge to accomplish.

AbstractThis cross-sectional study examined how energy density (ED) of meals and snacks are associated with overall diet quality and adiposity measures in 1617 British children aged 4–18 years from the 1997 National Diet and Nutrition Survey. On the basis of data from 7-d weighed dietary record, all eating occasions were divided into meals or snacks on the basis of time (meals: 06.00–09.00, 12.00–14.00 and 17.00–20.00 hours; snacks: all others) or contribution to energy intake (EI) (meals: ≥15 %; snacks: <15 %). ED of meals and snacks was calculated on the basis of food only. Overall diet quality was assessed using the Mediterranean diet score (range 0–8). Irrespective of the definition of meals and snacks, ≥67 % of EI was derived from meals, whereas ED of meals was lower than ED of snacks (mean: 8·50–8·75 v. 9·69–10·52 kJ/g). Both ED of meals and ED of snacks were inversely associated with total intakes of vegetables, fruits, dietary fibre and overall diet quality and positively associated with total intakes of fat. However, the associations were stronger for ED of meals. The change in the Mediterranean diet score with a 1-unit increase of ED (kJ/g) was −0·35 to −0·30 for ED of meals and −0·09 to −0·06 for ED of snacks (all P<0·0001). After adjustment for potential confounders, all measures of ED of meals and snacks did not show positive associations with adiposity measures. In conclusion, although both ED of meals and ED of snacks were associated with adverse profiles of overall diet quality (but not adiposity measures), stronger associations were observed for ED of meals.

Abstract The Mediterranean diet (MD) is a model of a healthy diet and healthy lifestyle. Adherence to the MD has been correlated with a reduction in many metabolic disorders including cancers. The factors associated with adolescents’ adherence to the MD in North Lebanon using the KIDMED index have never been explored. Therefore, we thought to examine these factors among a sample of them. A cross-sectional survey was conducted in the city of Tripoli, North Lebanon. A total of 798 adolescents aged 11-18 years were randomly selected to participate in this study. All participants completed a questionnaire assessing adherence to the MD (KIDMED index), physical activity (physical activity questionnaires for older children [PAQ-C] and adolescents [PAQ-A]), health-related quality of life (KIDSCREEN-27 index) and sociodemographic characteristics (age, gender, grade level and parents’ educational status). Anthropometric measurements, including weight, height and waist circumference, were also collected. Adherence to the MD was good among only 13.3% of the adolescents. The prevalence rate of overweight and obesity was elevated, affecting 36.9% of the students. Lower adherence to the MD was significantly correlated with skipping meals (p=0.001). Meanwhile, adolescents who were engaged in a high level of physical activity, those who consumed more meals with their families and those who benefited from better physical wellbeing had a better diet quality (p<0.001). Nutrition intervention programmes, as well as public health policies, would be of interest in order to improve diet quality among Lebanese adolescents.

Abstract. Results of epidemiologic studies and clinical trials have shown that subjects following the Mediterranean diet had lower inflammatory markers such as homocysteine (Hcy). Therefore, the aim of this cross-sectional study was to assess female diet quality with the Mediterranean diet quality index (MDQI) and to determine the correlation between MDQI, homocysteine, folate and vitamin B12 levels in the blood. The study participants were 237 apparently healthy women (96 of reproductive age and 141 postmenopausal) between 25 and 93 years. For each participant, 24-hour dietary recalls for 3 days were collected, MDQI was calculated, and plasma Hcy, serum and erythrocyte folate and vitamin B12 levels were analysed. Total MDQI ranged from 8 to 10 points, which represented a medium-poor diet for the subjects. The strength of correlation using biomarkers, regardless of group type, age, gender and other measured parameters, was ranked from best (0.11) to worst (0.52) for olive oil, fish, fruits and vegetables, grains, and meat, in this order. Hcy levels showed the best response among all markers across all groups and food types. Our study shows significant differences between variables of the MDQI and Hcy levels compared to levels of folate and vitamin B12 in participants with medium-poor diet quality, as evaluated according to MDQI scores.
