Construcción y validación de un atlas fotográfico de alimentos para niños de 1 a 5 años de Argentina / Development and validation of a photographic food atlas for children from 1 to 5 years of age in Argentina

Resumen Introducción: las fotografías de alimentos son ayudas que se utilizan para estimar el tamaño de las porciones en la evaluación dietética. Se ha demostrado que aquellas diseñadas para la población adulta son inapropiadas para evaluar la ingesta en niños. Actualmente, Argentina no cuenta con fotografías de alimentos diseñadas para la población de niños menores de 5 años. Objetivo: construir y validar un atlas fotográfico de alimentos para niños de 1 a 5 años de Argentina. Materiales y método: se realizó un estudio de investigación-acción que se dividió en dos etapas. En la primera se construyó un atlas fotográfico de alimentos y, en la segunda se validó el instrumento mediante un estudio exploratorio observacional transversal con enfoque cuali-cuantitativo llevado a cabo en dos establecimientos educativos de la ciudad de La Plata. El atlas fotográfico cuenta con 77 series de fotografías de alimentos. La validación se llevó a cabo mediante sesiones de percepción visual en tiempo real. Se realizó una valoración de las características visuales y del contenido del atlas por licenciadas en Nutrición mediante una encuesta semiestructurada. Resultados: participaron 168 padres o cuidadores voluntarios, 102 mujeres y 66 hombres. El número total de estimaciones del tamaño de la porción fue de 2856, de las cuales un 65,5% resultaron correctas. Los alimentos estimados por debajo del 60% fueron: sémola, puré de zapallo, zanahoria rallada, manzana, zapallito verde, ensalada de frutas y arroz con leche. El atlas fue valorado por 21 licenciadas en Nutrición, de las cuales a un 47,6% le pareció que el diseño y contenido eran adecuados. Conclusión: si bien se deben mejorar aquellas series que generaron dificultades en la estimación de la porción, el atlas fotográfico de alimentos resultó ser una herramienta útil para estimar la ingesta en niños de 1 a 5 años.

Abstract Introduction: food photographs are aids used in estimating portion sizes in dietary evaluation. Those designed for the adult population have been shown to be inappropriate for evaluating intake in children. Currently, Argentina does not have food photographs designed for the population of children under 5 years of age. Objective: To develop and validate a photographic food atlas for children from 1 to 5 years old in Argentina. Materials and method: an action-research study was carried out, divided into two stages. In the first, a photographic food atlas was develop and in the second, the instrument was validated through an exploratory cross-sectional observational study with a quali-quantitative approach carried out in two educational establishments in the city of La Plata. The photographic atlas has 77 series of food photographs. The validation was carried out through visual perception sessions in real time. An assessment of the visual characteristics and the content of the atlas was carried out by Nutrition Graduates through a semi-structured survey. Results: 168 voluntary parents or caregivers participated, 102 women and 66 men. The total number of portion size estimates was 2,856, of which 65.5% were correct. Foods estimated to be below 60% were semolina, pumpkin puree, grated carrot, apple, zucchini, fruit salad, and rice pudding. The atlas was evaluated by 21 Nutrition Graduates, of which 47.6% thought that its design and content were adequate. Conclusion: although those series that generated difficulties in estimating the portion should be improved, the photographic food atlas turned out to be a useful tool to estimate the intake in children aged 1 to 5.

Relative validation of a food frequency questionnaire to assess dietary fatty acid intake / Validación relativa de un cuestionario de frecuencia de alimentos para evaluar la ingesta dietaria de ácido graso

OBJECTIVES: This study aimed to develop and validate a Food Frequency Questionnaire (FFQ) for assessing consumption of fatty acids among pregnant women. METHODS: Two lists of foods were created according to percent contribution of each nutrient estimated by three 24-hour recalls: a long and short version FFQ to estimate long-chain polyunsaturated fatty acids (LCPUFAs). Student paired t-test and Pearson correlation coefficients were used to verify the differences in mean consumption of nutrients from the FFQ and 24-hour recall. The concordance between the consumption values of the two methods was assessed using the Bland-Altman method and quartiles concordance. RESULTS: For the FFQ - long version, correlation values ranged from 0.33 (<0.05) to 0.62 (<0.01) for docosahexaenoic acid (DHA) and linoleic acid (LA), respectively. Eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA) were not correlated. Exact concordance ranged from 49.0% (energy) to 22.4% (EPA), and discordance ranged from 14.3% (DPA) to 2.0% (Saturated). The FFQ - short version had high correlations for LCPUFAs. Exact concordance ranged from 36.7% (n-3 LCPUFA) to 16.3% (DHA); and discordance from 12.2% (DPA) to 2.0% (arachidonic acid). Bland-Altman analysis showed good concordance for both versions. CONCLUSION: This nutrient-specific FFQ is a valid instrument to be used to estimate the level of consumption of fatty acids among pregnant women.

OBJETIVO: Este estudio tuvo como objetivo desarrollar y validar un cuestionario de frecuencia de consumo de alimentos para evaluar el consumo de ácidos grasos en gestantes. MÉTODOS: Dos listas de alimentos fueron creadas de acuerdo con la contribución porcentual de cada nutriente estimado por 3 recordatorios de 24 horas: CFC - versión larga y CFC - versión corta para estimar ácidos grasos poliinsaturados de cadena larga (AGPICL). La prueba de t pareada de Student y el coeficiente de correlación de Pearson se utilizaron para verificar las diferencias entre el consumo medio de nutrientes de del CFC y el recordatorio de 24 horas. La concordancia entre los valores de consumo de los dos métodos se evaluó mediante el método de Bland-Altman y la concordancia de cuartiles. RESULTADOS: En CFC - versión larga, los valores de correlación oscilaron entre 0.33 (<0.05) y 0.62 (<0.01) para ácido docosahexaenoico (DHA) y ácido linoleico (LA), respectivamente. Ácido eicosapentaenoico (EPA) y ácido docosapentaenoico (DPA) no presentaron correlación. La concordancia exacta varió de 49,0% (energía) a 22,4% (EPA), y la discordancia varió de 14,3% (DPA) a 2,0% (saturado). CFC: la versión corta mostró los mejores valores de correlaciones para los AGPICL. La concordancia exacta varió de 36,7 (n-3 LCPUFA) a 16,3% (DHA); y discordancia de 12,2% (DPA) a 2,0% (ácido araquidónico). El análisis de Bland-Altman mostró una buena concordancia para ambas versiones. CONCLUSIÓN: Este método CFC específico de nutrientes es un instrumento válido que se utiliza para estimar el nivel de consumo de ácidos grasos en mujeres gestantes.

Comparison of 24 h recall and 3-day dietary cycle with 7-day dietary cycle as a tool for dietary assessment at community level in a rural South Indian community: A cross-sectional study

Background: Dietary assessment is important to give nutritional counseling, to monitor ongoing nutritional transition, and to initiate public health policies. However, dietary intake measurement is a challenge, as type of food, portion size, and food habits vary immensely. Objective: The objective of the study was to compare 24 h recall and 3-day dietary cycle with 7-day dietary cycle as dietary assessment tool at community level in the rural part of Southern part of India. Materials and Methods: It is a community-based cross-sectional study conducted in a rural community of H D Kote Taluk of Mysuru district. Fifty-five houses were selected randomly by lottery method. Medical social workers were trained and data were collected regarding dietary consumption from the households and analyzed using SPSS version 24. Results: Descriptive statistics such as mean and standard deviation were used and inferential statistics such as one-way analysis of variance showed a significant difference in the recorded calorie intake by three methods of dietary assessment; f (2,) = 10.109, P < 0.00. Bonferroni post hoc revealed significant higher recordings by 24 h recall method (2422.56 ± 1581) compared to 3-day dietary cycle (1462.14 ± 761) and 7-day dietary cycle (1782.97 ± 682.6). No significant statistical difference was noted between 3-day dietary cycle and 7-day dietary cycle. Conclusion: Three-day dietary cycle method could replace 7-day dietary cycle method for community-based dietary assessment, as it provides results comparable to the gold standard 7-day dietary assessment method and it is less time consuming, cost effective and ensures better compliance.

La investigación alimentaria en Venezuela. Perspectivas y desafíos / Food research in Venezuela. Perspectives and challenges

La evaluación dietética es una de las herramientas más importantes de la epidemiología nutricional, su práctica continúa siendo un reto para los profesionales de la Nutrición, que actualmente se enfrentan a cambios en el perfil epidemiológico de la población, avances científicos y tecnológicos, escasez de recursos y desigualdades sociales. Los estudios dietéticos, como cualquier otro tipo de investigación evaluativa, ven comprometidas su validez y confiabilidad ante debilidades técnicas y metodológicas que deben ser atendidas, durante el diseño y la ejecución. Venezuela, al igual que el resto de los países latinoamericanos, tiene una larga historia de investigación alimentaria, encontrando estudios que difieren en objetivos, tamaño de la muestra, tipo de muestreo, técnicas aplicadas, tratamiento estadístico, análisis y uso de la información. Actualmente, es indiscutible la necesidad de acercarse al consumo real de alimentos y nutrientes por parte de la población venezolana, contar con una línea base es indispensable para la formulación, implementación y evaluación de estrategias de intervención eficaces para el alcance de mayores niveles de salud nutricional y la prevención de enfermedades, que garanticen una vida activa y productiva para la población. Las nuevas exigencias y retos exhortan a la revisión permanente de conceptos, enfoques y protocolos de evaluación dietética. La invitación es a transitar por el fascinante campo de la investigación alimentaria y tomar lo mejor de los dos mundos: la rigurosidad científica que siempre se debió mantener y las oportunidades y desafíos que caracterizan a los nuevos tiempos(AU)

Dietary assessment is one of the most important tools in nutritional epidemiology; its practice continues to be a challenge for nutrition professionals, who are currently facing changes in the epidemiological profile of the population, scientific and technological advances, scarcity of resources and social inequalities. Dietary studies, like any other type of evaluative research, have their validity and reliability compromised in the face of technical and methodological weaknesses that must be addressed during design and execution. Venezuela, like the rest of the Latin American countries, has a long history of food research, finding studies that differ in objectives, sample size, type of sampling, applied techniques, statistical treatment, analysis and use of information. Currently, the need to approach the real consumption of food and nutrients by the Venezuelan population is indisputable; having a baseline is essential for the formulation, implementation and evaluation of effective intervention strategies to achieve higher levels of nutritional health and the prevention of diseases that guarantee an active and productive life for the population. The new demands and challenges call for the permanent revision of concepts, approaches and protocols for dietary assessment. The invitation is to travel through the fascinating field of food research and take the best of both worlds: the scientific rigor that always had to be maintained and the opportunities and challenges that characterize the new times(AU)

Validity and Acceptability of Image-based Food Record in Assessing Nutrient Intake among selected Malaysian Undergraduates

@#Introduction: Recognising the limitations of present dietary assessments method, recent attention had been drawn to image-based food record (IBFR) to assess dietary intake of the population. Thus, the present study aimed to compare nutrient intake assessed using IBFR with 24-hour diet recall (24DR) among nutrition and dietetics student. Method: There were 46 nutrition and dietetic undergraduates participated in the study, and information on the socio-demographic background and acceptability toward IBFR were obtained. Respondents were trained to complete one-day IBFR, and they were interviewed by researchers on the following day for their 24DR. Result: The mean age of respondents was 21.4±1.7 years old. The present study revealed that there were significantly higher protein and beta-carotene, but lower vitamin C reported by IBFR compared to 24DR. Medium to strong correlations were found between IBFR and 24DR for energy and nutrients intakes. The Bland-Altman analysis demonstrated a good level of agreement between IBFR and 24DR for energy and macronutrients (carbohydrates, protein and fat), respectively. The mean differences between IBFR and 24DR were -36 kcal for total daily energy intake, while mean differences of -12.24g, 0.79g, and 1.52g were reported for carbohydrates protein, and fat, respectively. Moderate level of agreement toward acceptability was demonstrated, and most of them (67.4%) preferred IBFR method. Conclusion: The present study revealed that IBFR showed a good level of agreement with 24DR in assessing nutrient intake. However, more extensive works should be considered to improve IBFR in assessing the energy and nutrients intake for the general population.

Prevalencia de ingesta inadecuada de micronutrientes en la población urbana de Costa Rica / Micronutrients inadequacy in urban population of Costa Rica

La inadecuación de micronutrientes es frecuente en los países en vías de desarrollo. En Costa Rica existe poca información acerca de la ingesta de micronutrientes y del impacto de los programas de fortificación obligatoria de alimentos. El objetivo de este estudio fue evaluar la ingesta de vitaminas y minerales y el aporte de la fortificación de alimentos a la ingesta total de micronutrientes en la población urbana costarricense. Se analizó el consumo de alimentos en una muestra de la población urbana costarricense, participantes del Estudio Latinoamericano de Nutrición y Salud (ELANS). El riesgo de ingesta inadecuada se estimó según sexo y grupo de edad, utilizando el método de punto de corte del Requerimiento Medio Estimado (EAR). Para el hierro, se utilizó el método de aproximación probabilística. Más del 85% de la muestra presentó riesgo de ingesta inadecuada para vitamina E, calcio y vitamina D. Una menor prevalencia de riesgo de ingesta inadecuada se presentó para la niacina, tiamina, folatos, hierro y selenio. La fortificación de alimentos tiene un efecto notorio en la ingesta de micronutrientes, especialmente de hierro, niacina, tiamina y folatos. La ingesta de calcio, vitamina D y vitamina E es preocupantemente inadecuada, siendo las mujeres y las personas mayores de 50 años los grupos más afectados. Resulta fundamental el establecimiento de programas y políticas públicas para asegurar el cumplimiento del requerimiento establecido para los diferentes micronutrientes(AU)

Micronutrient deficiencies are still very common in developing countries. In Costa Rica there is little information on micronutrients intake and the impact of food fortification.This study aimed to determine the contribution of food fortification to the total intake, and to estimate the risk of inadequate intake of vitamins and minerals in an urban Costa Rican population. As a part of the Latin American Nutrition and Health Study, we analyzed data from a nationally representative sample of 798 urban residents from Costa Rica (15-65 years old) whom provided two 24-h dietary recalls. The prevalence of inadequate micronutrient intake was estimated according to the EAR cut-point method. Iron was analyze using the probability approach. We observed a 100% of the sample are at risk of inadequate intake of vitamin D, and similar percentages were obtained for calcium and vitamin E, ranging from 92.9 to 100% and 85.5 to 99.2% respectively. A lower risk of inadequate intake was observed for niacin, thiamin, folate, iron and selenium. Food fortificationmakes an important contribution to folate, thiamin, iron and niacin intake. Despite the efforts that have been made to ensure adequate micronutrient intake in Costa Rica, the intake of calcium, vitamin D and vitamin E is still very low, especially among women and people over 50 are the most affected. Based on the above, it is recommended to promote a healthy diet through nutritional education as part of public health policies, in order to facilitates compliance to nutritional requirement(AU)

Study On the Validity Of Instant Photography Method For Dietary Assessment In Undergraduate College Students

Background A healthy diet in a college student life is critical to ensure their normal growth, study anddevelopment.Aim In order to accurately assess the dietary pattern of college students and guide it, our study aims to evaluatethe validity of instant photography as an alternative dietary assessment method in college students.Methods Nine participants were enrolled and given a presentation on dietary assessment methods, includingweighing, 24-hour recall, and instant photography. The participants took pictures of their foods from three anglesbefore and after eating for constant seven days, foods weighing was completed by others. Then, the participantsrecalled the foods’ weights after 24 hours. Two trained observers estimated food weight from the digital images(n = 285) gathered at the end of the study with the aid of Chinese food atlas reference.Results Instant photograph showed significant correlation with weighing method on food weights of grains,tubers, vegetables, fruits, meat and eggs (all P ≤ 0.01). 24-hour method had similar correlation with weighingmethod on food weights except fruits. Compared with 24-hour recall, instant photograph displayedunderestimation on weights of grains, tubers, vegetables, and meat. However, instant photograph had moreaccurate estimations on weights of fruits and egg. Furthermore, compared with nutrients data from weighingmethod, both instant photography and 24-hour recall methods showed promising estimations on the amounts ofenergy, protein, fat, carbohydrate, vitamin A, vitamin C, vitamin E, calcium, iron and zinc (all P < 0.001). Comparedwith 24-hour recall, instant photograph displayed underestimation on the amounts of energy, protein, fat,carbohydrate, vitamin A, vitamin C, vitamin E, zinc. However, instant photograph had a more accurate estimationon calcium.

The development of food image detection and recognition model of Korean food for mobile dietary management

BACKGROUND/OBJECTIVES: The aim of this study was to develop Korean food image detection and recognition model for use in mobile devices for accurate estimation of dietary intake. SUBJECTS/METHODS: We collected food images by taking pictures or by searching web images and built an image dataset for use in training a complex recognition model for Korean food. Augmentation techniques were performed in order to increase the dataset size. The dataset for training contained more than 92,000 images categorized into 23 groups of Korean food. All images were down-sampled to a fixed resolution of 150 × 150 and then randomly divided into training and testing groups at a ratio of 3:1, resulting in 69,000 training images and 23,000 test images. We used a Deep Convolutional Neural Network (DCNN) for the complex recognition model and compared the results with those of other networks: AlexNet, GoogLeNet, Very Deep Convolutional Neural Network, VGG and ResNet, for large-scale image recognition. RESULTS: Our complex food recognition model, K-foodNet, had higher test accuracy (91.3%) and faster recognition time (0.4 ms) than those of the other networks. CONCLUSION: The results showed that K-foodNet achieved better performance in detecting and recognizing Korean food compared to other state-of-the-art models.

Gender Analysis of Food Items Selection for Food Frequency Questionnaire Development

BACKGROUND: The aims of this study were 1) to compare foods between men and women with high contributions to absolute intake and the variability in energy and nutrient intakes, which are common criteria of selecting foods for food frequency questionnaire (FFQ), 2) to analyze possible inaccuracies due to not taking gender into consideration. METHODS: The study used 1-day 24 hour recall data of 7,952 participants (n=3,250 men, n=4,702 women) aged 19–64 years who participated in the 2013–2014 Korea National Health and Nutrition Examination Survey. Foods which have high possibility of being included in FFQ items, called candidate foods, were selected by analyzing their contribution to absolute intake and variability in the intakes of energy and 15 nutrients in total participants, men and women. RESULTS: The number of candidate foods selected was 133 for total participants, 126 for men, and 153 for women. Intakes of candidate foods for total participants were significantly higher in energy and six nutrients out of selected 16 nutrients than those of candidate foods for men only. On the contrary, all nutrient intakes of candidate foods for total participants were significantly lower than those of candidate foods for women only. CONCLUSIONS: Differences were revealed between men and women not only in the total numbers, but also in the selected food items from the candidate foods for FFQ. Thus, developing FFQs without considering gender may produce systematic errors in dietary assessment, possibly in different directions for men and women.

Relationships between Obesity and Dietary Habits of Preschool Children and Their Parents in Dongducheon Based on the Nutrition Quotient (NQ) / 대한지역사회영양학회지

OBJECTIVES: This study was conducted to investigate the associations between obesity and the children's Nutrition Quotient (NQ) and to further examine the relationships between NQ and mini dietary assessment (MDA) of their parents. METHODS: The subjects were 355 children aged 3 to 5 years and their parents in Dongducheon. We collected parental-reported NQ questionnaires for children and MDA of parents. Anthropometric measurements, height, weight and BMI by BIA were measured in children. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Statistical analyses consisted of the chi-squared test, ANOVA, partial correlations and logistic regression analysis adjustments for parents BMI. RESULTS: Approximately 20.8% of preschool children were classified as overweight or obese. Underweight children showed a significantly higher score for balance than overweight children. The NQ of the children was 61.9 ± 11.6, and NQ scores and their parents' MDA did not exhibit any significant differences according to degree of obesity. After adjusting for parent's BMI, children's BMI was significantly correlated with balance and moderation among NQ factors. Parent's MDA showed significant correlation with their children's NQ, balance, diversity, moderation, regularity, practice and NQ grade, except for diversity of father. Additionally, NQ grade had a significantly increased (150.1%) odds ratio (OR) of being overweight (95% CI 1.008–2.234). CONCLUSIONS: These results show that NQ for children is influenced by their parents' MDA and BMI. Furthermore, our findings support the association between overweight prevention and improvement of NQ grade among preschool children.

Validity of household dietary diversity score as a measure of food insecurity among households in Lucena City, Quezon

@#<p style="text-align: justify;"><strong>BACKGROUND AND OBJECTIVE</strong>: Food security is a multifaceted issue experienced by nations worldwide. A trend currently being explored in recent studies in measuring food security at the micro level is the Dietary Diversity Score (DDS). Household Dietary Diversity Score (HDDS), a type of DDS, obtains a snapshot of the economic ability of a household, making it an effective food insecurity indicator. The objective of this study was to assess the validity of the HDDS as a tool for measuring food insecurity.<br /><br /><strong>METHODOLOGY</strong>: The study employed a cross-sectional analytic design with 368 study households in Lucena City, Quezon Philippines. Household Food Insecurity Access Scale (HFIAS) and Household Mean Adequacy Ratio (HHMAR), being two of the most frequently used methods in measuring household food insecurity, were used as reference standards to assess the validity of the HDDS in identifying food insecure households. Receiver Operating Curve (ROC) Analysis was done to determine the appropriate HDDS cut-off for identifying food insecure households.<br /><br /><strong>RESULTS</strong>: The areas under the curve (AUC) obtained (0.618, 0.70, 0.701, 0.743), classified HDDS as a "fair indicator" of food insecurity. HDDS of 6 was identified as the optimal score when evaluating food insecurity withconsideration of sensitivity and specificity.<br /><br /><strong>CONCLUSION</strong>: In this study, HDDS was proven to be a valid measure of food insecurity. It shows the great potential of this quick assessment tool in identifying population-at-risk, which is crucial in the design of a timely and appropriate intervention to alleviate food insecurity and other nutrition and health-related problems whichmay arise.</p>

Development and User Satisfaction of a Mobile Phone Application for Image-based Dietary Assessment / 대한지역사회영양학회지

OBJECTIVES: The objective of this study was to develop mobile phone application for image-based dietary assessment and evaluate satisfaction regarding respondent's use of the mobile phone application. METHODS: We developed a mobile phone application to assess dietary intakes using 24 hour dietary recall. After initial development, application was reviewed by ten adults and revised based on their comments. We recruited 192 volunteers (92 males, 100 females) to use the mobile phone application and to respond to a satisfaction survey. Participants were instructed to use the mobile phone application with fiducial marker five centimeter in width, length and two centimeter height at each eating occasion during designated 4 days, capturing 45° angle and 90° angle images of all food and beverage items before and after consumption. After using the mobile phone application for 4 days, participants were asked to complete an online questionnaire on the satisfaction of the mobile phone app. User satisfaction items composed of 12 questions of application user interface, 8 questions of emotional response, 9 questions of eating behavior in 5 likert scale. Participants were also asked to provide additional open-ended comments on the use of mobile phone application. Statistical analysis was performed by using the SPSS 23.0 (Statistical Package for the Social Science). RESULTS: The average user interface score was 2.82 ± 1.08, which was close to the ‘normal’ response. Responses for emotion and eating behavior also were borderline to the ‘normal’. CONCLUSIONS: This study found that the mobile phone application using 24-hour recall was acceptable to be used to assess dietary intakes for several days. However, there should be a need for such technology to be user-oriented instead of researcher-oriented. Easy and cost-effective new technology is needed for estimating the amounts of food eaten automatically when the photos are taken.

Relative validity of a food frequency questionnaire to identify dietary patterns in an adult Mexican population / Validez relativa del cuestionario de frecuencia de alimentos para identificar patrones dietarios en adultos Mexicanos

Abstract: Objective: To examine the validity of a semi-quantitative food frequency questionnaire (SFFQ) to identify dietary patterns in an adult Mexican population. Materials and methods: A 140-item SFFQ and two 24-hour dietary recalls (24DRs) were administered. Foods were categorized into 29 food groups used to derive dietary patterns via factor analysis. Pearson and intraclass correlations coefficients between dietary pattern scores identified from the SFFQ and 24DRs were assessed. Results: Pattern 1 was high in snacks, fast food, soft drinks, processed meats and refined grains; pattern 2 was high in fresh vegetables, fresh fruits, and dairy products; and pattern 3 was high in legumes, eggs, sweetened foods and sugars. Pearson correlation coefficients between the SFFQ and the 24DRs for these patterns were 0.66 (P<0.001), 0.41 (P<0.001) and 0.29 (P=0.193) respectively. Conclusions: Our data indicate reasonable validity of the SFFQ, using factor analysis, to derive major dietary patterns in comparison with two 24DR.

Material y métodos: Un CFA de 140-alimentos y dos recordatorios de 24-horas (24DRs) fueron obtenidos. Los alimentos fueron categorizados en 29 grupos para derivar los patrones dietarios mediante análisis factorial. La validez se evaluó mediante coeficientes de correlación intraclase y de Pearson (CCP) entre los puntajes de los patrones dietarios identificados con CFA y 24DRs. Resultados: El patrón 1 fue alto en bocadillos, carnes procesadas, comida rápida, refrescos y granos refinados; el patrón 2 estuvo caracterizado por vegetales, frutas y lácteos; y el patrón 3 se caracterizó por leguminosas, huevo, azucares, y alimentos dulces. Los CCP entre estos patrones fueron 0.66 (P<0.001), 0.41 (P<0.001) y 0.29 (P=0.193) respectivamente. Conclusión: Los datos sugieren razonable validez del CFA, utilizando análisis factorial, para derivar patrones dietarios en comparación con el 24DRs.

Dietary assessment according to frequency of food consumed away from home among children and adolescents: Based on the 2010~2012 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: The aim of this study was to investigate the dietary quality of food consumed away from home among Korean children and adolescents. METHODS: Data were obtained from the 2010~2012 KNHANES (Korea National Health and Nutrition Examination Survey) and included 3,583 subjects aged 7 to 18 years old. The frequency of food consumed away from home was dichotomized into more than once or less than once per day. RESULTS: Thirty percent of subjects were shown to consume food away from home more than once per day, and older children from higher income households showed a higher frequency of food consumed away from home compared to other children. The percentage of children and adolescents cited as regularly skipping breakfast was 19%. Individuals who ate out more than once per day showed higher consumption of energy and sodium than those who ate out less than once per day. CONCLUSION: Excessive intakes of energy and sodium are associated with obesity, high blood pressure, diabetes, and obesity-related diseases. Thus, there is a need for nutritional intervention and educational efforts to improve child nutrition and prevent obesity.

Dietary assessment according to intake of Korean soup and stew in Korean adults: Based on the 2011~2014 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: This study was conducted to conduct dietary assessment of Korean adults according to intake of Korean soup and stew. METHODS: To accomplish this study, 20,926 adults aged 19 yr or higher who participated in the dietary intake survey (24 h recall method) were analyzed from the data of the 2011~2014 Korea National Health and Nutrition Examination Survey (KNHANES). The items included in the soup and stew were guk, tang, jjigae, jijimi, and jeongol. RESULTS: Intakes of soup and stew of subjects were divided into quartiles; intake range by quartile was Q1: < 22.96 g, Q2: 22.96~98.75 g, Q3: 98.75~212.23 g, and Q4: ≥ 212.24 g. In the case of the Q4 group, male, married, employed, higher educated, and high income subjects showed increased intakes of soup and stew. In addition, sodium intake among nutrient intakes increased from 3,849.04 mg in Q1 group to 5,363.57 mg in Q4 group. Intakes of cereals/grains, potatoes/starches, legumes, seeds/nuts, vegetables, mushrooms, fruits, meat, fishes/shell fishes, milks/dairy products, oils/fats, and seasonings among all foods significantly increased from Q1 group to Q4 group. Lastly, in the multivariable regression analysis, male, higher age, married, eating breakfast, consumption of snacks, prepared meals from home/institution, average eating-out frequency per week, energy consumption, and sodium intake related parameters increased intake of Korean soup and stew. CONCLUSION: Excessive intake of sodium was related to high blood pressure and metabolic syndrome. Thus, there are needs to improve dietary guidelines and nutrition education for balanced intake of soup and stew.

Dietary Habits, Dietary Behaviors, Depression and Stress according to Self-Rated Health of University Students in Kyungnam Province

The purpose of this study was to investigate health-related habits, dietary habits, depression, stress, satisfaction of body weight, mini-dietary assessment (MDA) and dietary behaviors according to self-rated health among 255 university students in Kyungnam province. Statistical analyses were performed using the SPSS software package (version 19.0). The average ages of the subjects were 21.1 years. Participants were asked their self-rated health and 109, 105 and 41 students answered themselves as "healthy", "normal" and "unhealthy", respectively. The pocket money (P<0.05) was related with self-rated health, and meal frequency (P<0.01) of healthy group was higher than that of the unhealthy group. The self-reported depression level (P<0.01) and the score of depression (P<0.05) of the healthy group were lower than those of the unhealthy group. The self-reported stress level of the healthy group (P<0.05) was higher than that of the unhealthy group. The scores of nutritional behavior (P<0.05) and MDA (P<0.01) of the healthy group were higher than those of the unhealthy group. The scores for intakes of meat, fish, egg or beans, cereals and vegetables except kimchi, fruits, balanced diet and various foods were higher in the healthy group than in the unhealthy group. Our results suggest that pocket money, high meal frequency, low depression, satisfaction of present body weight, and good dietary behavior might influence good perception of self-rated health.
