Several instruments developed to assess dietary intake of groups or populations have strengths and weaknesses that affect their specific application. No self-administered, closed-ended dietary survey was previously used in Argentina to assess current food and nutrient intake on a daily basis. To design and validate a self-administered, structured food record NutriQuid, NQ representative of the adult Argentine population's food consumption pattern to measure individual energy and nutrient intake. Records were loaded onto a database using software that checks a regional nutrition information system SARA Basic dietary assessment methodsautomatically quantifying energy and nutrient intake. Data analysis Basic dietary assessment methods descriptive statistics, repeated measures ANOVA, intraclass correlation coefficient, nonparametric regression, and cross-classification into quintiles. Dietary records or food diaries can be highlighted among dietary assessment methods of the current diet for their interest and validity. It is a prospective, open-ended survey method collecting data about the foods and beverages consumed over a previously specified period of time. Dietary records can be used to estimate current diet of individuals and population groups, as well as to identify groups at risk of inadequacy. It is a dietary assessment method interesting for its use in epidemiological or in clinical studies. High validity and precision has been reported for the method when used following adequate procedures and considering the sufficient number of days. Thus, dietary records are often considered as a reference method in validation studies. Dieta cetogenica keto gratis. Como adelgazar mas rapido las piernas Ampollas de mesoterapia para adelgazar.

Any tool that provides a simple method facilitating the collection of data about dietary intake without changing behavior is an important advancement in nutritional epidemiology However, though it is possible to analyze the data on a continuous scale using another type of statistical analysisthe research team preferred to analyze the collected data by organizing them Basic dietary assessment methods categories as Basic dietary assessment methods variables.
One inherent limitation to most FFQs is that they are paper-based forms. Thus, errors such as Basic dietary assessment methods questions or multiple marks are common. Furthermore, data from paper Basic dietary assessment methods must be entered into analysis software, which makes it unfeasible to provide real-time feedback in a clinical setting In their most simple application, paper FFQ match web-based FFQ; this allows the flexibility of using either a paper or computerized questionnaire interchangeably, but the benefits from computer administration are limited to direct data entry, real-time error checking and rapid analysis 4,7.
Other advantages include reducing paper use, postage costs, and the space, security, and organization required for paper file Basic dietary assessment methods 9. Additionally, on-line methods can be used to target specific geographical population groups and can be accessed remotely 1.
The research team considered that in this study the potential disadvantages of developing a web-based FFQ, in comparison with a paper-based FFQ, outweighed its potential benefits, Basic dietary assessment methods in mind two inherent characteristics of this study: the paper-based FFQ used is very short and simple containing only 12 items and the sample is made up of students from the Medical and Pharmacy Schools at the of Seville.
The simplicity of the short paper FFQ reduced the chance for errors, the amount of paper consumed, and storage space issues. The relatively easy access to the sample population made it possible to complete the short paper FFQ in person, making it unnecessary to mail it. In this Basic dietary assessment methods, the costs associated with data entry were minimal compared with 50 thermomix mg disociada Dieta potential costs of developing a web-based FFQ In recent years, many well-established FFQs have been developed into web-based versions and there is a growing body of evidence demonstrating that data from web-based FFQs are Basic dietary assessment methods with data from printed versions 1.
The strengths of the current study include using more than one statistical method in order to give credence to the results 30 and adequate sample size Basic dietary assessment methods of the characteristics of these types of mobile technologies, such as asynchronythe ease with which privacy can be maintained 40as well as the light workload for the participants one minute per dayhelped to here participation.
Limitation of this study is that the participants involved were students; the majority were women which is actually a reflection of the proportion of male and female students enrolled Basic dietary assessment methods the Schools of Medicine and Pharmacy at the University of Seville and were, therefore, representative of a convenient sample rather than a nationally representative sample. Another possible limitation is that the access to these technologies is not universal, excluding especially vulnerable groups, such as students from poorer social strata or elderly students.
Due to the growing popularity of mobile phones among young Spaniards, this instrument Basic dietary assessment methods likely to be accepted by this population and could reduce some of the inherent limitations Basic dietary assessment methods in paper FFQs, such as dependence on the memory of participants and the impossibility of reflecting day-to-day intrapersonal variability in dietary intake.

There is a great necessity for new methods of determination of habitual dietary intake that overcome the limitations of these traditional methods. Results: One hundred and nineteen participants completed the study The average weighted kappa statistic was 0. Verification that NQ recorded data could : 1 reflect caloric and nutrient intake characteristic of our target population according to previous measurements in our region 17—19 here 2 identify Basic dietary assessment methods differences in food consumption on different Basic dietary assessment methods of the week definition of minimum number of days necessary to attain this aim ; 3 be easy to keep for seven days and be well-accepted by the respondent; and 4 simplify data entry and further data processing.
This phase lasted from August to Octoberincorporating adult volunteers aged 45—75 years living in the same geographical areas as those participating in the PPDBA. We increased this number toconsidering possible exclusion of incomplete questionnaires and dropouts. Participants 80 women and 40 men aged 45—75 received the NQ, and were asked to record seven consecutive days of complete food and drinks consumption.
The day material was given to participants varied so that the first day of recording included all seven days of the week. At the end of the recording Basic dietary assessment methods, food records were collected by a member of the research team.
Basic dietary assessment methods in phase 1, records were completed anonymously, but participants wrote the last four digits of their identification card on the NQ to avoid overlapping data from different participants and to facilitate further analysis.

This study was conducted according to Helsinki Declaration guidelines, and all procedures involving human subjects were approved by the Ethics Committee of the National University of La Plata, Argentina. First phase : we used descriptive statistical techniques to estimate total energy consumption, carbohydrates, protein, fat and micronutrients recorded in the NQ. Subsequently, the percentage difference between values more info by volunteers and reference nutritionist for each variable was calculated and tested for significance Basic dietary assessment methods paired data.
Pearson correlation coefficients and cross-classification Basic dietary assessment methods quintiles of intake were also determined. Second phase 7 consecutive days individual recordsANOVA for repeated measures was used to assess differences between individual daily records; Basic dietary assessment methods the intra-class correlation coefficient ICC from a two-way mixed ANOVA model as a measure of test-retest Basic dietary assessment methods of each NQ component.
ICC assessed reproducibility of daily measurements of the same person for each NQ component total energy and different nutrients throughout the study week.

Cross-classification by quintiles of non-energy adjusted intakes for the structured food record NutriQuid obtained from records completed by study group participants vs.
Total fat difference recorded was affected by an underestimation of vegetable fat intake. Ninety-one percent of the Basic dietary assessment methods participants returned their completed questionnaires, thus gathering records of daily food intake over seven consecutive days Table Daily consumption of energy and nutrients.

Daily energy consumption. These variations resulted from higher consumption over the weekend. Higher consumption over the weekend induced significant differences in total energy, carbohydrates, saturated fatty acids, refined sugars, and vegetable fat but not in the remaining nutrients. ICC values for each dietary component ranged from 0.
We developed a self-administered-closed-ended record of daily food intake for adults in Argentina to assess individual nutrient intake in large cohort intervention studies. For economic and infrastructure considerations, we used a paper-based version rather than a computer-based tool used by others. Instead, we chose an see more approach in a controlled setting: Basic dietary assessment methods of untrained respondents to a nutritionist reference true value.
In fact, this test represents a great challenge for the method because it compares data provided by a nutritionist science professional who prepared the meals with the data provided by Basic dietary assessment methods volunteers in the field of nutrition.
The small difference in the data provided by the reference nutritionist and the link, indicates the easy comprehension of the NutriQuid protocol. We found underreporting of energy and nutrient intake, common Basic dietary assessment methods dietary assessment methods, specifically in fat intake. This contributed greatly to the mean difference in total fat, polyunsaturated fatty acid and energy intake learn more here participants and reference records.
Consequently, to improve NQ efficiency, we will modify the instruction leaflet introducing an easy household guide to help participants to estimate portion size consumed and Basic dietary assessment methods the importance of recording oil used in meal preparation. The underestimation of salt, vegetable oil source of PUFA and grated cheese source of calcium by the participants, could be ascribed to the fact that their content in the tested meals was known and thus appropriately recorded by the reference nutritionist while this knowledge was completely ignored by the participants.
Other authors also reported difficulties in estimating intake of certain foods, in particular salt, oil, and added fat. We will further add a drawing with different serving sizes using a teaspoon and its fractions. Our NQ validity indicators are comparable to those reported by other local authors using different methodology.
Comparison with other validation studies may be limited by their different methodological approaches. Recent studies compared Basic dietary assessment methods methods new against an established methodbut recording Basic dietary assessment methods differed winter and Basic dietary assessment methods. Impact of seasonal differences in food availability have been identified in a recent meta-analysis.
This approach was only possible in a closed setting using hospital in-patients.
Dietary assessment methods: dietary records.
Self-administered questionnaires are economically advantageous compared to other methods. Basic dietary assessment methods software developed to evaluate nutrient link from this survey by consultation with different databases enabled their immediate full identification Table 3 and reflected the caloric and macronutrient intake characteristics of our target population Argentinian adults, 45—75 years old.
NQ sensitivity allowed to detection of small changes Basic dietary assessment methods energy and nutrient consumption, e. The weekly NQ assessment also demonstrated highly acceptable ICC values for total energy, carbohydrates, refined sugars, protein, fiber, sodium, and potassium, but lower for vegetable and animal fat.

Anne Chinnock 1. San José-Costa Rica. Artículo recibido: 27 de abril de Aceptado: 29 de junio de Como citar este artículo: Chinnock A. Perspect Basic dietary assessment methods Humana. Objective: Develop a food frequency questionnaire FFQ and assess its ability to rank a group of adults according to nutrient intake by a comparison with food records.
Methods : This study consisted of 2 stages. A Development of FFQ. Analysis of a food consumption database from a group of 60 adults from communities in the Central Valley of Costa Rica led to the identification of 10 food groups which contributed to check this out of between-person variance in energy Basic dietary assessment methods nutrient intake.
A quantitative FFQ containing foods Basic dietary assessment methods the 10 Basic dietary assessment methods and covering 7 days was developed. B Data was collected using the FFQ and a 4-day food record Basic dietary assessment methods a group of https://vagina.titan-quest.info/articles20531-tuby.php adult inhabitants of an urban community in San José.
Energy and nutrient intake as estimated by both methods were compared using Pearson's correlation coefficients and Student's t-test. Results : Pearson's correlation coefficients were above 0,4 for 18 of the 22 crude nutrient intakes. The degree of association was lower for energy-adjusted intakes, reflecting underestimation of energy intakes by the FFQ. Conclusions : When compared with the food record, the FFQ Basic dietary assessment methods able to rank the individuals according to crude nutrient intake.
However, due to underestimation of total energy intake by the FFQ, the correlations for the energy-adjusted values were poorer. The FFQ requires some modifications in its design and its reproducibility and validity must be demonstrated before being used in epidemiological studies in Costa Rica.
Key words: Basic dietary assessment methods consumption, energy intake, nutritional epidemiology, nutrition surveys, dietary assessment, epidemiologic studies, questionnaires. Materiales y metódos :el estudio consistió en dos etapas. Se elaboró un CFCA cuantitativo con alimentos pertenecientes a los 10 grupos y que cubría 7 días. Se compararon las ingestas de energía y nutrientes estimados por ambos métodos por medio de coeficientes de correlación de Pearson y la prueba t de Student.
Resultados Basic dietary assessment methods las coeficientes de correlación de Pearson para 18 de los 22 nutrientes crudos fueron mayores a 0,4. El grado de asociación para las ingestas ajustadas por energía fue menor, debido a subestimación en la ingesta de energía por el CFCA. El CFCA requiere algunas modificaciones y su reproducibilidad y validez debe ser demostrado antes de poder utilizarlo en estudios epidemiológicos en Basic dietary assessment methods Rica.
Palabras clave: consumo de alimentos, ingesta de energía, epidemiología nutricional, encuestas nutricionales, estudios epidemiológicos, cuestionarios. Such a method must be able to measure food consumption relatively easily, with sufficient accuracy and at a reasonable cost.
One of the early studies in this Basic dietary assessment methods was reported by Heady 1who tried to develop a 'short-cut method of classifying diets of thousands of middle-aged men'.
Basic dietary assessment methods on, the Food Frequency Questionnaire FFQ https://costocondritis.titan-quest.info/articles18864-nuvet.php been widely studied as a method which can estimate energy and nutrient intake in large groups of population for epidemiological studies.
Cade Basic dietary assessment methodsin a review of the literature on FFQs, reports validation studies using this method. Among the most widely used FFQ are those developed by Willet and Hankin, authors who have described different methods Basic dietary assessment methods developing this type of questionnaire 3, 4.
The only validation study of a FFQ has been reported by Kabagambe et al 5 who assessed the validity and reproducibility of a modified version of the item FFQ developed by Willett et al 6 among adults. This leads one to the question of how a FFQ, using a food list developed from data on food consumption among a group of Costa Rican adults, would perform in terms of its ability to rank individuals according to nutrient intake. This article presents the results of the first stage in the development of such a method.
Firstly, the method used to develop a quantitative FFQ Basic dietary assessment methods described and then the ability of the questionnaire to rank a group of adults according to their intake of different nutrients is tested using data from Food Records as a standard.
Identification of indicators. At the click here of this study, an attempt was made to identify food consumption variables that could serve as indicators of energy and nutrient intake. In order to do this, a database of food consumption and nutrient intake from Costa Rican adults Basic dietary assessment methods used.
The database comes from an earlier investigation involving 60 Costa Rican adults 15 men and 15 women from a rural community and 15 men and 15 women from an urban area all within the Central Valley of Costa Rica who carried out 7-day weighed food records. The methods and characteristics Basic dietary assessment methods this investigation have been published 7. The following dependent variables Basic dietary assessment methods obtained for Basic dietary assessment methods of the 60 adults from this data base: average intake of energy and nutrients protein, carbohydrates, total fat, monounsaturated fat, polyunsaturated fat, saturated fat, retinol equivalents, vitamin C, thiamin, riboflavin, vitamin B6, folate, vitamin B12, iron, magnesium, phosphorus, zinc, calcium, potassium, dietary fibre and cholesterol.
The following independent variables were developed:. Consumption of 39 different food groups.
High validity and precision has been reported for Basic dietary assessment methods method when used following adequate procedures and considering the sufficient number of days.
Thus, dietary records are often considered as a reference method in validation studies. Nevertheless, the method is affected by error and has limitations due mainly to the tendency of subjects to report food consumption close Basic dietary assessment methods those socially desirable. Additional problems are related to the high burden posed on respondents.
