Measuring Skin Carotenoids Using Reflection Spectroscopy in a Low-Income School Setting.

Dietary behavior change is difficult to accurately measure in a low-income youth population. Objective tools to measure fruit and vegetable consumption without relying on self-report present the opportunity to do this with less respondent burden and bias. A promising tool for quantifying fruit and vegetable consumption via proxy is skin carotenoids as measured by reflection spectroscopy through a device called the Veggie Meter®. To assess whether the Veggie Meter® is able to detect changes in skin carotenoids as a proxy for fruit and vegetable consumption in a low-income school setting, skin carotenoid measurements were collected at three time points, along with student level demographics, anthropometric measurements, and nutrition knowledge. A secondary goal of this study was to refine the protocol to be used based on researcher observations. Repeated measures analysis of variance with Bonferroni correction for multiple comparisons indicate that there was a significant difference in VM scores over the course of the study (F(2, 68) = 6.63, p = 0.002), with an increase in skin carotenoids from Fall 2018 to Spring 2019 (p = 0.005). This increase was sustained over the summer months when measured in Fall 2019. Changes to the protocol included the addition of a hand cleaning step and using the non-dominant ring finger for data collection. With these refinements, the results demonstrate that the Veggie Meter® is usable as a non-invasive tool for measuring fruit and vegetable consumption in a population that is traditionally difficult to assess.

Relative validity and reproducibility of a food frequency questionnaire to evaluate food group intakes among Jordanian children and adolescents.

INTRODUCTION: Introduction: studies of the impact of diet on the prevention and occurrence of diseases in all life stages require a reliable and valid dietary assessment tool for assessing dietary intake. Objectives: this study aimed to develop and evaluate the relative validity and reproducibility of a culturally sensitive quantitative food frequency questionnaire (FFQ) to assess food group intake among Jordanian children and adolescents. Methods: the validation study was carried out on 136 children and adolescents aged between 6 and 18 years who enrolled from selected public and private schools. Fifty of these children and adolescents participated in the reproducibility phase. Food group intake from a quantitative FFQ was compared with food group intake from 24-hour dietary recalls (24h-DRs). Four 24-HRs were collected weekly for one month. Results: intraclass correlation coefficients between the two FFQs ranged from 0.18 for nuts to 0.98 for tea. De-attenuated and energy-adjusted correlations ranged from 0.08 for nuts to 0.95 for vegetable oils. On average, 46.6 % and 43.6 % of participants were ranked by the FFQ-1 and the 24h-DRs into the same quartile based on their crude and energy-adjusted food group intake, respectively. Bland-Altman plots showed a satisfactory agreement between the two methods for milk and milk products and vegetables. Conclusions: the findings of this study suggested that the developed FFQ has excellent reproducibility and good relative validity for most food groups.

INTRODUCCIÓN: Introducción: los estudios sobre el impacto de la dieta en la prevención y aparición de enfermedades en todas las etapas de la vida requieren una herramienta de evaluación dietética confiable y válida para evaluar la ingesta dietética. Objetivos: este estudio tuvo como objetivo desarrollar y evaluar la validez relativa y la reproducibilidad de un cuestionario cuantitativo de frecuencia alimentaria (CFC) culturalmente sensible para evaluar la ingesta de grupos de alimentos entre niños y adolescentes jordanos. Métodos: el estudio de validación se realizó en 136 niños y adolescentes de entre 6 y 18 años matriculados en escuelas públicas y privadas seleccionadas. Cincuenta de estos niños y adolescentes participaron en la fase de reproducibilidad. La ingesta del grupo de alimentos de un CFC cuantitativo se comparó con la ingesta del grupo de alimentos de los recordatorios dietéticos de 24 horas. Se recogieron cuatro recordatorios de 024 horas semanales durante un mes. Resultados: los coeficientes de correlación intraclase entre los dos CFC variaron de 0,18 para las nueces a 0,98 para el té. Las correlaciones atenuadas y ajustadas por energía variaron de 0,08 para las nueces a 0,95 para los aceites vegetales. En promedio, el 46,6 % y el 43,6 % de los participantes fueron clasificados por el CFC-1 y el 24h-DR en el mismo cuartil en función de la ingesta de grupo de alimentos crudos y ajustados por energía, respectivamente. Los gráficos de Bland-Altman mostraron una concordancia satisfactoria entre los dos métodos para la leche y los productos lácteos y las hortalizas. Conclusiones: los hallazgos de este estudio sugirieron que el CFC desarrollado tiene una excelente reproducibilidad y una buena validez relativa para la mayoría de los grupos de alimentos.

Validation of a food frequency questionnaire as a tool for assessing dietary intake in cardiovascular disease research and surveillance in Bangladesh.

BACKGROUND: Cardiovascular disease (CVD) has emerged as a major public health concern in Bangladesh. Diet is an established risk factor for CVD but a tool to assess dietary intake in Bangladesh is lacking. This study aimed to validate a food frequency questionnaire (FFQ) using the 24-h dietary recall method and corresponding nutritional biological markers among rural and urban populations of Bangladesh. METHOD: Participants of both genders aged 18-60 years were included in the analysis (total n = 146, rural n = 94 and urban n = 52). Two FFQs of 166 items were administered three-months apart, during which time three 24-h dietary recalls were also completed. Participants were asked to recall their frequency of consumption over the preceding 3 months. Urine and blood samples were collected for comparison between FFQ-estimates of nutrients and their corresponding biomarkers. Methods were compared using unadjusted, energy-adjusted, de-attenuated correlation coefficients, 95% limits of agreement (LOA) and quartile classification. RESULTS: Fair to moderate agreement for ranking energy, macro and micronutrients into quartiles was observed (weighted k value ranged from 0.22 to 0.58; p < 0.001 for unadjusted data) except for vitamin D (weighted k - 0.05) and zinc (weighted k 0.09). Correlation coefficients of crude energy, macronutrients and common micronutrients including vitamin E, thiamine, riboflavin, niacin, pyridoxine, folate, iron, magnesium, phosphorus, potassium, and sodium were moderately good, ranging from 0.42 to 0.78; p < 0.001 but only fair for vitamin A, ß carotene and calcium (0.31 to 0.38; p < 0.001) and poor for vitamin D and zinc (0.02 and 0.16; p = ns, respectively). Energy-adjusted correlations were generally lower except for fat and vitamin E, and in range of - 0.017 (for calcium) to 0.686 (for fat). De-attenuated correlations were higher than unadjusted and energy- adjusted, and significant for all nutrients except for vitamin D (0.017) to 0.801 (for carbohydrate). The Bland Altman tests demonstrated that most of the coefficients were positive which indicated that FFQ provided a greater overestimation at higher intakes. More than one in three participants appeared to overestimate their food consumption based on the ratio of energy intake to basal metabolic rate cut points suggested by Goldberg. Absolute intake of macronutrients was 1.5 times higher and for micronutrients it ranged from 1.07 (sodium) to 26 times (Zinc). FFQ estimates correlated well for sodium (0.32; p < 0.001), and vitamin D (0.20; p = 0.017) with their corresponding biomarkers and iron (0.25; p = 0.003) with serum ferritin for unadjusted data. Folate, iron (with haemoglobin) and total protein showed inverse association; and fat and potassium showed poor correlation with their corresponding biomarkers for unadjusted data. However, folate showed significant positive correlation (0.189; p = 0.025) with biomarker after energy adjustment. CONCLUSION: Although FFQ showed overestimation for absolute intake in comparison with 24-h recalls, the validation study demonstrated acceptable agreement for ranking dietary intakes from FFQ with 24-h recall methods and some biomarkers and therefore could be considered as a tool to measure dietary intake for research and CVD risk factors surveillance in Bangladesh. The instrument may not be appropriate for monitoring population adherence to recommended intakes because of the overestimation.

Use of the Veggie Meter® as a tool to objectively approximate fruit and vegetable intake among youth for evaluation of preschool and school-based interventions.

BACKGROUND: Reflection spectroscopy is an emerging, non-invasive objective measure used to approximate fruit and vegetable intake. The present study aimed to use a reflection spectroscopy device (the Veggie Meter®, Longevity Link Corporation, Salt Lake City, UT, USA) to assess skin carotenoid status in preschool, middle- and high-school students and to examine associations between skin carotenoids and self-reported dietary intake. METHODS: In Autumn 2018, we used the Veggie Meter® to assess skin carotenoids and age-appropriate validated dietary assessment measures to approximate fruit and vegetable (FV) intake. Preschool participants completed a previously validated pictorial liking tool using an iPad (Apple Inc., Cupertino, CA, USA). Middle-school participants completed selected questions from the validated School Physical Activity and Nutrition (SPAN) (Michael & Susan Dell Center for Healthy Living, University of Texas, Austin, TX, USA) questionnaire regarding frequency of their FV and beverage intake on the previous day, with additional questions about physical activity. High-school participants' FV intake was assessed using the Fruit and Vegetable Screener (National Cancer Institute, Bethesda, MD, USA). Spearman correlation coefficients were used to determine bivariate associations between measures of dietary intake and Veggie Meter®-assessed skin carotenoid levels. RESULTS: Mean (SD) Veggie Meter® readings were 266 (82.9), 219 (68.1) and 216 (67.2) among preschool, middle- and high-school students. There was an inverse association between soda intake and Veggie Meter® readings (r = -0.22, P = 0.03) among middle-school students; and a positive association between daily fruit intake and Veggie Meter® readings (r = 0.25, P = 0.06) among high-school students. CONCLUSIONS: The Veggie Meter® comprises a promising evaluation tool for preschool and school-based nutrition interventions.

Influence of dietary intake and decision-making during pregnancy on birth outcomes.

AIM: This study aimed to examine dietary intake and decision-making in a cohort of pregnant South-East Queensland women to determine compliance with dietary guidelines and the relationships between dietary intake, decision-making and birth outcomes. METHODS: Pregnant women attending maternity services at participating hospitals reported food frequency and motivations using the Maternal Outcomes and Nutrition Tool, a novel digital instrument. Birth outcomes were sourced from hospital records. A cross-sectional cohort design was used to examine the data. RESULTS: Analysis demonstrated suboptimal intake of core food groups; meat and alternatives (median [IQR]) (2.6 [2.0-3.4] serves/day) and grains (3.1 [2.1-4.1]) fell below recommendations; fruit (3.8 [2.5-5.3]) and discretionary foods (3.1 [2.1-4.4]) exceeded them. Hypertensive disorders demonstrated a negative linear relationship with vegetable intake (P = .017). Cultural diversity was significantly associated with decreased birthweight (P = .022) but increased intake of meat and alternatives (3.1 vs 2.6, P < .001) compared to Caucasian women; median intake of meat and alternatives was lower in women who reported smoking in the examined time frame. Smokers were less likely to declare health motives for food selection than non-smokers; smoking and health were inversely associated with increasing maternal age. Food choice was primarily sensory-driven. CONCLUSIONS: This cohort demonstrated poor adherence to dietary guidelines. Culturally and linguistically diverse women and smokers exhibit dietary behaviours which may contribute to suboptimal birth outcomes; targeted nutrition counselling may improve outcomes in these women. These findings highlight the need for transdisciplinary maternity care and provide a foundation for further research aimed at optimising nutrition-related birth outcomes in at-risk groups.

Relative Validity of Starch and Sugar Intake in Japanese Adults as Estimated With Comprehensive and Brief Self-Administered Diet History Questionnaires.

BACKGROUND: In Japan, large-scale epidemiological studies on starch and sugar intake are scarce, mainly due to a lack of a suitable assessment tool. We examined the relative validity of two widely-used dietary assessment questionnaires for Japanese adults, the comprehensive Diet History Questionnaire (DHQ) and the brief DHQ (BDHQ), for estimating the intake of starch and 10 types of sugars: total sugar, sucrose, maltose, lactose, trehalose, glucose, fructose, galactose, and added and free sugars. METHODS: A total of 92 women and 92 men completed 4-day weighed dietary records (DRs) besides the DHQ and BDHQ in each of the four seasons. For each method, starch and sugar intake was calculated according to a recently developed food composition database on starch and sugars for Japanese food items. RESULTS: For most of the carbohydrate variables examined, the median energy-adjusted intake derived from the first DHQ and BDHQ (DHQ1 and BDHQ1, respectively) significantly differed from those derived from the 16-day DRs in both sexes. Spearman correlation coefficients between the 16-day DRs and DHQ1 were acceptable (≥0.31) for all variables (0.31-0.67), except for maltose and trehalose in women (≤0.29). For BDHQ1, the correlations were also acceptable for all variables (0.32-0.64), except for maltose (≤0.26) and galactose (≤0.06). Similar results were observed for the mean of four DHQs and BDHQs. CONCLUSIONS: This study indicated a reasonable ranking ability of DHQ and BDHQ for the intake of starch and most sugars examined, despite a poor ability to estimate the intake at the both group and individual levels.

Objetivo: avaliar o estado nutricional e o consumo alimentar das principais fontes de macro e micronutrientes ingeridos por pré-escolares. Método: trata-se de estudo exploratório-descritivo, transversal e com abordagem quantitativa, composto por 269 crianças de ambos os sexos com idade entre 3 e 5 anos dos centros municipais de educação infantil de Montes Claros, Minas Gerais. Realizou-se inquérito alimentar e a avaliação antropométrica no ambiente escolar, mediante a autorização dos pais e/ou responsáveis. Resultados: verifica-se que a maioria das crianças se encontram eutróficas de acordo com todos os critérios avaliados. No inquérito alimentar, apenas o consumo de calorias totais e ferro encontrava-se adequado para a faixa etária. Entre os macronutrientes, o consumo de carboidratos, lipídeos e proteínas estava acima do valor recomendado. Dentre os micronutrientes, observa-se o consumo aumentado de zinco, sódio e vitamina C. No entanto, a ingestão de micronutrientes como o cálcio, magnésio, vitaminas A, D e E encontrava-se abaixo do recomendado, além das fibras. Conclusão: observa-se que o estado nutricional das crianças está adequado, porém há inadequação na ingestão alimentar. Este fator pode contribuir com o aumento no índice de sobrepeso e obesidade, e estar associado com as deficiências nutricionais.(AU)

Objective: to assess the nutritional status and food consumption of the main sources of macro and micronutrients ingested by preschool children. Method: This is an exploratory-descriptive, cross-sectional with a quantitative approach study, composed of 269 children of both sexes aged between 3 and 5 years of child municipal education centers in the city of Montes Claros, Minas Gerais. A food survey and anthropometric evaluation were carried out in the school environment, with the authorization of parents and/or guardians. Results: It appears that most of the children are eutrophic according to all the evaluated criteria. In the investigation of food, only the consumption of calories and iron was appropriate for the age range. Among the macronutrients, the consumption of carbohydrates, lipids and proteins was above the recommended value. Among the micronutrients, an increased consumption of zinc, sodium and vitamin C was observed. However, the intake of micronutrients such as calcium, magnesium, vitamins A, D and E was below the recommended levels, as well as the fibers consumption. Conclusion: It is observed that the nutritional status of children is appropriate, but there is inadequate food intake. This factor may contribute to the increase in overweight and obesity and may also be associated with nutritional deficiencies.(AU)

The use of wearable cameras in assessing children's dietary intake and behaviours in China.

The use of lifelogging device in dietary assessments can reduce misreporting and underreporting, which are common in the previous studies conventional methods. We performed the first study in Chinese children (primary school Grade 4) that applied the wearable cameras in assisting dietary recall. Children (n = 52) wore the wearable cameras (Narrative Clip 2) for seven consecutive days, during which they completed a 3-day 24-h dietary recall at home. Then children modified their dietary recalls at school by reviewing the photos taken by the wearable camera at school, with the assistance of the investigator, and generated the camera-assisted 24-h dietary recalls. Compared with camera-assisted dietary recalls, 8% (n = 160) and 1% (n = 11) of food items were underreported (i.e. not reported at all) and misreported (i.e. reported in an incorrect amount) by dietary recalls without camera-assistance, respectively. Dietary recalls without camera assistance underestimated daily energy intake by 149 ±â€¯182 kcal/d (8%) in comparison to the camera-assisted dietary recalls. Foods consumed on the snacking occasions (40%) were more likely to be underreported than those consumed at main meals (P < 0.001). Beverages (37%), fruits (30%), snacks and desserts (16%) were foods most likely to be inaccurately reported. Children were satisfied with the wearable cameras, with a median score 5.0 (IQR: 5.0-5.0) for most features. Wearable cameras hold promise for improving accuracy of dietary intake assessment in children, providing rich objective information on dietary behaviours, and received high level of satisfaction and compliance of the users. Our results suggest that the accuracy of dietary recall among Chinse school-aged children could be improved by wearable camera, especially avoiding underreporting in the snacking occasions.

Development of a dietary screening questionnaire to predict excessive weight gain in pregnancy.

Excessive gestational weight gain (GWG) is a risk factor for several adverse pregnancy outcomes, including macrosomia. Diet is one of the few modifiable risk factors identified. However, most dietary assessment methods are impractical for use in maternal care. This study evaluated whether a short dietary screening questionnaire could be used as a predictor of excessive GWG in a cohort of Icelandic women. The dietary data were collected in gestational weeks 11-14, using a 40-item food frequency screening questionnaire. The dietary data were transformed into 13 predefined dietary risk factors for an inadequate diet. Stepwise backward elimination was used to identify a reduced set of factors that best predicted excessive GWG. This set of variables was then used to calculate a combined dietary risk score (range 0-5). Information regarding outcomes, GWG (n = 1,326) and birth weight (n = 1,651), was extracted from maternal hospital records. In total, 36% had excessive GWG (Icelandic criteria), and 5% of infants were macrosomic (≥4,500 g). A high dietary risk score (characterized by a nonvaried diet, nonadequate frequency of consumption of fruits/vegetables, dairy, and whole grain intake, and excessive intake of sugar/artificially sweetened beverages and dairy) was associated with a higher risk of excessive GWG. Women with a high (≥4) versus low (≤2) risk score had higher risk of excessive GWG (relative risk = 1.23, 95% confidence interval, CI [1.002, 1.50]) and higher odds of delivering a macrosomic offspring (odds ratio = 2.20, 95% CI [1.14, 4.25]). The results indicate that asking simple questions about women's dietary intake early in pregnancy could identify women who should be prioritized for further dietary counselling and support.

Padrão de consumo dietético de gestantes e sua relação com a insegurança alimentar no domicílio / Dietary intake patterns of pregnant women and its relationship with food insecurity at household

Introdução: Na gestação, as demandas energéticas estão aumentadas visando à promoção de um adequado desenvolvimento. Tal grupo populacional, quando acometido pela insegurança alimentar (IA), tem comprometimento na qualidade da alimentação, pois há influência no consumo de alimentos. Método: Estudo transversal com gestantes atendidas pela rede pública de saúde de Maceió, AL, em 2014. O padrão de consumo dietético foi avaliado por meio de recordatórios alimentares de 24 horas e de questionário de frequência de consumo alimentar, e a presença da IA no domicílio pela Escala Brasileira de IA, com utilização dos testes do χ2 e o teste T de Student, considerando p<0,05 como significativo. Resultados: Foram estudadas 356 gestantes, sendo 42,7% com IA. A maioria tinha elevado consumo diário de arroz (95,5%), feijão (82,0%) e pães (72,7%). Por outro lado, leite e derivados (53,3%), ovos (26,5%) e as carnes (59,0%) foram alimentos de baixo consumo, sendo o último ainda menor nas gestantes com IA (p=0,025). Adicionalmente, esse padrão de consumo refletiu em uma alimentação com baixo aporte energético, dos micronutrientes ácido fólico, ferro, selênio, zinco e cálcio, e de fibras. Conclusão: O padrão de consumo alimentar das gestantes estudadas é caracterizado pelo baixo consumo energético e de nutrientes essenciais ao bom êxito da gravidez. A presença da IA no domicílio não levou a maior comprometimento desse padrão dietético, exceção ao consumo de carnes.(AU)

Introduction: During the pregnancy the energy demands are increased aimed at promoting a proper development. This population group when affected by food insecurity (FI) has compromised the quality of food, it influences on food consumption. Methods: Cross-sectional study of pregnant women by the public health Maceió, AL, in 2014. The pattern of dietary intake was assessed by food 24-hour recalls and a questionnaire of food intake frequency, and the presence of FI in home by the Brazilian Scale FI, using the χ2 and Student's t test, considering p<0.05 as significant. Results: We studied 356 pregnant women, being 42.7% FI. Most had high daily consumption of rice (95.5%), beans (82.0%) and bread (72.7%). On the other hand, dairy products (53.3%), eggs (26.5%) and meat (59.0%) were low-energy food, the latter being even lower in pregnant women with FI (p=0.025). In addition, this consumption pattern reflected in a power low energy intake, micronutrients folic acid, iron, selenium, zinc and calcium and fiber. Conclusion: The dietary patterns of pregnant women studied is characterized by low energy and nutrients essential to the successful pregnancy. The presence of FI in the household has not led to greater commitment of this dietary pattern, except to meat consumption, which it was lower in the presence of FI.(AU)

Introdução: O câncer possui um dos maiores índices de mortalidade no mundo, sendo o câncer de mama o que mais atinge a população do sexo feminino. Método: Estudo transversal, com aferição de medidas antropométricas e utilização de questionário inquérito alimentar recordatório de 24 horas, de frequência alimentar, e análise da qualidade da dieta com o uso do instrumento Healthy Eating Index (HEI- 2010), em uma amostra de 59 mulheres diagnosticadas com câncer de mama, em tratamento de quimioterapia na Unidade de Alta Complexidade em Oncologia (UNACON) vinculada a um hospital público da Serra Gaúcha. Análise dos dados com o uso do teste Qui-Quadrado de Pearson. Foram consideradas significativas as associações com p<0,05. Resultados: A maior parte das mulheres entrevistadas diagnosticadas com câncer de mama apresentou sobrepeso (45,8%). Quanto à qualidade da dieta, 55,9% apresentaram qualidade moderada e 44,1%, inadequada. As entrevistadas classificadas com dieta moderada apresentaram melhor situação nutricional, além da prática de atividade física e de não possuírem o hábito de fumar ou consumir bebidas alcoólicas. Observou-se associação entre o consumo de gordura saturada em dietas inadequadas (p=0,047), e o consumo adequado de frutas e verduras, fator positivo para prevenção de recidivas do câncer de mama. Conclusão: Encontramos um grande número de mulheres que não adotaram uma alimentação e estilo de vida mais saudável juntamente com a prática de atividade física, a fim de que esse risco fosse diminuído para prevenir a recidiva da doença.(AU)

Introduction: The cancer has one of the highest mortality rates in the world, and the breast cancer that affects more the female population. Methods: Cross-sectional study, with anthropometric measurements and use of dietary survey questionnaire and 24-hour food frequency, and it is analyzed the diet quality with the instrument Healthy Eating Index (HEI 2010) with a sample of 59 women diagnosed with breast cancer in chemotherapy treatment at the Unit of High Complexity in Oncology (UNACON) linked to a public hospital in Serra Gaúcha. The data analysis is done through Pearson's chi-square test. It was considered significant associations with p<0.05. Results: Most of the interviewed women diagnosed with breast cancer were overweight (45.8%). In terms of the diet quality, 55.9% of them had moderate diet quality and 44.1% of them had an inadequate diet. The interviewees, who had the moderate diet classification, had better nutritional status, due to practicing physical activity and not having the habit of smoking or drinking alcohol. It was observed an association between saturated fat consumption by inappropriate diets (p=0.047), and appropriate consumption of fruits and vegetables, positive for prevention of breast cancer recurrence. Conclusion: We found a large number of women, who did not have a healthy life style, good feeding and physical activity so that this risk is decreased to prevent the disease recurrence.(AU)

Evaluation of a mobile application for estimation of food intake / Avaliação de um aplicativo móvel para a estimativa de ingestão alimentar

ABSTRACT Objective: Evaluate the use of the Nutrabem (São Paulo, Brasil) mobile application as a tool for measurement of food intake among university students. Methods: Cross-sectional study of a random sample of 40 undergraduate students at the Universidade Federal de São Paulo, Campus Baixada Santista. Food intake data were estimated using the Nutrabem app and the 24-hour dietary recall. Intakes of energy, carbohydrates, proteins, lipids, calcium, iron, and vitamin C were calculated. The intake of food groups and diet quality were evaluated by the Diet Quality Index associated with the Digital Food Guide. The agreement between the methods was assessed using the Pearson's correlation coefficient and the Student' t-test. Results: Strong correlations were observed between energy (0.77), carbohydrates (0.82) and protein (0.83). The groups: poultry, fish, and eggs; beef and pork; refined grains and breads; and fruits and legumes showed strong correlations (between 0.76 and 0.85). There were moderate correlations (0.59 and 0.71) between the groups sugars and sweets; whole grains, tubers and roots, milk and dairy products, animal fats, and the Diet Quality Index associated with the Digital Food Guide scores. Vegetables and leafy greens, nuts, and vegetable oils showed weak correlations (0.31 and 0.43). Homogeneity assessment revealed similarity between the results obtained by both methods (p>0.05) . Conclusion: The Nutrabem app can be used as a tool to assess dietary intake among university students since it produces results similar to those obtained by the 24-hour dietary recall method.

RESUMO Objetivo: Avaliar a utilização do aplicativo Nutrabem (São Paulo) como recurso para a medida da ingestão alimentar entre universitários. Métodos: Estudo transversal conduzido em uma amostra aleatória com 40 universitários adultos da Universidade Federal de São Paulo, Campus Baixada Santista. Os dados de ingestão alimentar foram estimados por meio do aplicativo Nutrabem e pelo Recordatório de 24 horas; foram calculados os valores de ingestão de energia, carboidratos, proteínas, lipídeos, cálcio, ferro e vitamina C; avaliou-se ainda a ingestão segundo grupos alimentares e qualidade da dieta conforme o Índice de Qualidade da Dieta associado ao Guia Alimentar Digital. A concordância entre os métodos foi estimada pelo coeficiente de correlação linear Pearson e Teste-t. Resultados: Foram observadas correlações fortes para energia (0,77), carboidratos (0,82) e proteínas (0,83). Os grupos aves, pescados e ovos, carnes bovina e suína, cereais e pães refinados, frutas e leguminosas apresentaram correlações fortes (entre 0,76 e 0,85); açúcares e doces, cereais integrais, tubérculos e raízes, leite e derivados, gorduras de origem animal e a pontuação do Índice de Qualidade da Dieta associado ao Guia Alimentar Digital apresentam correlações moderadas (0,59 e 0,71); hortaliças, oleaginosas e os óleos vegetais apresentam correlações fracas (valores entre 0,31 e 0,43). A avaliação de homogeneidade dos dados mostrou haver semelhança entre os resultados obtidos por ambos os métodos (p>0,05) . Conclusão: O aplicativo Nutrabem pode ser mais uma ferramenta no estudo de ingestão alimentar de jovens universitários, uma vez que produz resultados semelhantes aos obtidos pelo Recordatório de 24 horas.

Dietary quality varies according to data collection instrument: a comparison between a food frequency questionnaire and 24-hour recall.

The objective of this study was to assess the agreement between the Brazilian Healthy Eating Index - Revised (BHEI-R), estimated by a food frequency questionnaire (FFQ) and multiple 24-hour recalls (24h-R). The Wilcoxon paired test, partial correlations (PC), intraclass correlation coefficient (ICC), and Bland-Altman method were used. The total BHEI-R scores and its components ("total fruits", "whole fruits", "total vegetables", "integral cereals", "saturated fat", "sodium", and "energy intake derived from solid fat, added sugar, and alcoholic beverages") were statistically different, with the ICC and PC indicating poor concordance and correlation. The mean concordance estimated for the total BHEI-R and its components varied from 68% for "integral cereals" to 147% for "whole fruits". The suitable concordance limits were violated for most of the components of the BHEI-R. Poor concordance was observed between the BHEI-R estimated by the FFQ and by multiple 24h-R, which indicated a strong reliability of the BHEI-R on the instrument used to collect information on food consumption.

A Mobile Phone Based Method to Assess Energy and Food Intake in Young Children: A Validation Study against the Doubly Labelled Water Method and 24 h Dietary Recalls.

Mobile phones are becoming important instruments for assessing diet and energy intake. We developed the Tool for Energy Balance in Children (TECH), which uses a mobile phone to assess energy and food intake in pre-school children. The aims of this study were: (a) to compare energy intake (EI) using TECH with total energy expenditure (TEE) measured via doubly labelled water (DLW); and (b) to compare intakes of fruits, vegetables, fruit juice, sweetened beverages, candy, ice cream, and bakery products using TECH with intakes acquired by 24 h dietary recalls. Participants were 39 healthy, Swedish children (5.5 ± 0.5 years) within the ongoing Mobile-based Intervention Intended to Stop Obesity in Preschoolers (MINISTOP) obesity prevention trial. Energy and food intakes were assessed during four days using TECH and 24 h telephone dietary recalls. Mean EI (TECH) was not statistically different from TEE (DLW) (5820 ± 820 kJ/24 h and 6040 ± 680 kJ/24 h, respectively). No significant differences in the average food intakes using TECH and 24 h dietary recalls were found. All food intakes were correlated between TECH and the 24 h dietary recalls (ρ = 0.665-0.896, p < 0.001). In conclusion, TECH accurately estimated the average intakes of energy and selected foods and thus has the potential to be a useful tool for dietary studies in pre-school children, for example obesity prevention trials.

Use of electronic visual recording to aid assessment of dietary intake of Australian Aboriginal children living in remote communities.

OBJECTIVE: To assess the feasibility of using electronic visual recording in combination with food records to evaluate dietary intake in Aboriginal infants and children. METHODS: All foods and drinks consumed by the child over four consecutive days were recorded in daily food records and pictures or videos. Feasibility was assessed by determining i) proportion of meals reported to be consumed; ii) cost of data collection; iii) day-to-day variation in energy intake and; iv) acceptability of the method. RESULTS: Dietary intake data was collected from three girls and five boys aged 11 months to eight years, five over four days and three during one day, at a cost of $3,300 per child. One-third of the 89 meals reported to be consumed through the food records were electronically recorded. Most photographs were taken in the first two days with the number of meals electronically recorded decreasing each day over the four-day period. There was a large day-to-day variation in energy intake. CONCLUSIONS: Use of electronic recording to aid individual usual dietary intake data collection was feasible. Collection periods spread over 1-2 weeks may be more appropriate due to the large variance in day-to-day dietary intake.

Dietary quality varies according to data collection instrument: a comparison between a food frequency questionnaire and 24-hour recall / A qualidade da dieta varia de acordo com o instrumento de obtenção de dados: comparação entre questionário de frequência alimentar e recordatório de 24 horas / La calidad de la dieta varía de acuerdo a lo instrumento de obtención de datos: comparación de cuestionario de frecuencia alimentaria y recordatorio de 24 horas

Abstract The objective of this study was to assess the agreement between the Brazilian Healthy Eating Index – Revised (BHEI-R), estimated by a food frequency questionnaire (FFQ) and multiple 24-hour recalls (24h-R). The Wilcoxon paired test, partial correlations (PC), intraclass correlation coefficient (ICC), and Bland-Altman method were used. The total BHEI-R scores and its components (“total fruits”, “whole fruits”, “total vegetables”, “integral cereals”, “saturated fat”, “sodium”, and “energy intake derived from solid fat, added sugar, and alcoholic beverages”) were statistically different, with the ICC and PC indicating poor concordance and correlation. The mean concordance estimated for the total BHEI-R and its components varied from 68% for “integral cereals” to 147% for “whole fruits”. The suitable concordance limits were violated for most of the components of the BHEI-R. Poor concordance was observed between the BHEI-R estimated by the FFQ and by multiple 24h-R, which indicated a strong reliability of the BHEI-R on the instrument used to collect information on food consumption.

Resumo O objetivo do estudo foi avaliar a concordância entre o Índice de Qualidade da Dieta Revisado (IQD-R), estimado por questionário de frequência alimentar (QFA) e recordatório de 24 horas (R24h). O teste de Wilcoxon, correlações parciais (CP), coeficiente de correlação intra-classe (CCI) e o método Bland-Altman foram usados. Os escores totais do IQD-R e seus componentes (“frutas totais”, “frutas inteiras”, “vegetais totais”, “cerais integrais”, “gordura saturada”, “sódio” e “ingestão de energia derivada de gordura sólida, adicionados de açúcar e bebidas alcoólicas” foram estatisticamente diferentes, com o CCI e as CP indicando baixa concordância e correlação. A concordância média estimada para o IQD-R total e seus componentes variou de 68% para “cereais integrais” e 147% para as “frutas inteiras”. Os limites adequados de concordância foram ultrapassados para a maior parte dos componentes do IQD-R. Observou-se baixa concordância entre o IQD-R estimado pelo QFA e por múltiplos R24h, o que indica uma forte confiabilidade do IQD-R no instrumento usado para coletar informações sobre o consumo alimentar.

Resumen El objetivo del estudio fue evaluar la correlación entre el Índice de Calidad de la Dieta Revisado (ICD-R), estimado por cuestionario de frecuencia de alimentos (CFA) y recordatorio de 24 horas (R24h). Se utilizó la prueba de Wilcoxon, correlaciones parciales (CP), coeficiente de correlación intraclase (CCI) y el método de Bland-Altman. Las puntuaciones totales del ICD-R y sus componentes (“total de frutas”, “frutas enteras”, “vegetales totales”, “granos integrales”, “grasa saturada”, “sodio” y “consumo de energía derivada de grasa sólida, agregado de azúcar y alcohol”) fueron estadísticamente diferentes, con el CCI y el CP indicando baja concordancia y correlación. La concordancia media estimada para el ICD-R total y sus componentes varió de 68% para los “granos integrales” y 147% para las “frutas enteras”. Los límites adecuados de concordancia fureon excedidos para la mayor parte de los componentes del ICD-R. Se observó baja concordancia entre el ICD-R estimado por el CFA y múltiples R24h, lo que indica una fuerte confiabilidad del ICD-R en el instrumento que se utiliza para recopilar información sobre el consumo de alimentos.

KIDMED TEST; PREVALENCE OF LOW ADHERENCE TO THE MEDITERRANEAN DIET IN CHILDREN AND YOUNG; A SYSTEMATIC REVIEW.

INTRODUCTION: during the last decades, a quick and important modification of the dietary habits has been observed in the Mediterranean countries, especially among young people. Several authors have evaluated the pattern of adherence to the Mediterranean Diet in this group of population, by using the KIDMED test. OBJECTIVES: the purpose of this study was to evaluate the adherence to the Mediterranean Diet among children and adolescents by using the KIDMED test through a systematic review and meta-analysis. METHODS: PubMed database was accessed until January 2014. Only cross-sectional studies evaluating children and young people were included. A random effects model was considered. RESULTS: eighteen cross-sectional studies were included. The population age ranged from 2 to 25 years. The total sample included 24 067 people. The overall percentage of high adherence to the Mediterranean Diet was 10% (95% CI 0.07-0.13), while the low adhesion was 21% (IC 95% 0.14 to 0.27). In the low adherence group, further analyses were performed by defined subgroups, finding differences for the age of the population and the geographical area. CONCLUSION: the results obtained showed important differences between high and low adherence to the Mediterranean Diet levels, although successive subgroup analyzes were performed. There is a clear trend towards the abandonment of the Mediterranean lifestyle.

Varios autores han evaluado el patrón de adhesión a la Dieta Mediterránea en este grupo de población, mediante el uso de la prueba KIDMED. Objetivos: el objetivo de este estudio fue evaluar la adhesión a la Dieta Mediterránea entre los niños y adolescentes mediante el uso de la prueba KIDMED a través de una revisión sistemática y un metaanálisis. Métodos: la base de datos PubMed fue revisada hasta enero de 2014. Los estudios incluidos solo fueron los transversales que evaluaron a niños y a jóvenes. Se consideró un modelo de efectos aleatorios. Resultados: se incluyeron dieciocho estudios transversales. La edad de la población varió de 2 a 25 años. La muestra total incluyó 24.067 personas. El porcentaje global de alta adhesión a la Dieta Mediterránea fue del 10% (IC del 95%: 0,07 a 0,13), mientras que la baja adhesión fue del 21% (IC 95%: 0,14 a 0,27). Nuevos análisis por subgrupos definidos fueron realizados en el grupo de baja adhesión, encontrando diferencias para la edad de la población y para la zona geográfica. Conclusión: los resultados obtenidos mostraron diferencias importantes entre alta y baja adhesión a la Dieta Mediterránea, a pesar de los sucesivos análisis de subgrupos que se realizaron. Existe una clara tendencia hacia el abandono del estilo de vida mediterráneo.

A systematic review of brief dietary questionnaires suitable for clinical use in the prevention and management of obesity, cardiovascular disease and type 2 diabetes.

The aim of this systematic review was to identify and describe brief dietary assessment tools suitable for use in clinical practice in the management of obesity, cardiovascular disease and type 2 diabetes. Papers describing development of brief (<35 items) dietary assessment questionnaires, that were accessible, simple to score and assessed aspects of the diet of relevance to the conditions of interest were identified from electronic databases. The development of 35 tools was described in 47 papers. Ten tools assessed healthy eating or healthy dietary patterns, 2 assessed adherence to the Mediterranean diet, 18 assessed dietary fat intake, and 5 assessed vegetable and/or fruit intake. Twenty tools were developed in North America. Test-retest reliability was conducted on 18 tools; correlation coefficients for total scores ranged from 0.59 to 0.95. Relative validation was conducted on 34 tools. The most common reference variable was percentage energy from fat (15 tools) and correlation coefficients ranged from 0.24, P<0.001 to 0.79, P<0.002. Tools that have been evaluated for reliability and/or relative validity are suitable for guiding clinicians when providing dietary advice. Variation in study design, settings and populations makes it difficult to recommend one tool over another, although future developers can enhance the understanding and use of tools by giving clear guidance as to the strengths and limitations of the study design. When selecting a tool, clinicians should consider whether their patient population is similar in characteristics to the evaluation sample.

Estimates of self-reported dietary behavior related to oral health among adolescents according to the type of food.

OBJECTIVE: To compare estimates of food behavior related to oral health obtained through a self-report measure and 24 hour dietary recalls (R24h). METHOD: We applied three R24h and one self-report measure in 87 adolescents. The estimates for eleven food items were compared at individual and group levels. RESULTS: No significant differences in mean values were found for ice cream, vegetables and biscuits without filling. For the remaining items, the values reported by the adolescents were higher than the values estimated by R24h. The percentage of adolescents who reported intake frequency of 1 or more times/ day was higher than the value obtained through R24h for all food items except soft drinks. The highest values of crude agreement between the instruments, individually, were found in the biscuits without filling (75.9%) and ice cream (72.4%). CONCLUSION: The results suggest that adolescents tend to report a degree of exposure to the food items larger than what they actually experience in their daily lives.
