“…The present study showed agreement between the methods used to estimate dietary intake for the nutritional variables, energy, and six nutrients, representing a larger number of variables than that reported in most studies available, which usually consider only the macronutrients 30 . Based on the data analysis, it can be said that the use of digital technology improves the quality of the data collected when compared to the use of conventional methods, as shown in similar studies 22,23,28,29 .…”

A B S T R A C T ObjectiveEvaluate the use of the Nutrabem (São Paulo, Brasil) mobile application as a tool for measurement of food intake among university students. MethodsCross-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. ResultsStrong 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). ConclusionThe 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.

“…Sabe-se que o QFA é um instrumento de boa validade e reprodutibilidade, entretanto não está isento de erros. A coleta de dados realizada por entrevistadores capacitados e treinados minimizou vícios de classificação, contudo é preciso considerar limitações do método, uma vez que depende da memória e da capacidade do entrevistado de relatar os alimentos e porções consumidos (SELEM et al, 2014). Além disso, sabe-se que a obesidade é uma …”

RESUMO:O trigo é amplamente utilizado na alimentação humana e ocupa o primeiro lugar em volume de produção mundial. Esta pesquisa teve como objetivo avaliar o consumo de derivados de trigo pela população de Maringá, Paraná, e sua correlação com fatores demográficos e estado nutricional. A pesquisa foi de natureza quantitativa com coleta de dados transversal. Foram avaliados 270 indivíduos adultos com idade entre 20 a 59 anos, de ambos os sexos. Os indivíduos foram abordados nos supermercados da cidade de Maringá, Paraná. Utilizaram-se dois questionários para coleta de dados. No primeiro continham perguntas sobre o perfil dos indivíduos entrevistados (sexo, idade, cor, escolaridade, renda familiar, peso, estatura e Índice de Massa Corporal -IMC). No segundo continha o Questionário de Frequência Alimentar Quantitativo (QFA), utilizado para avaliar o consumo de derivados de trigo. As informações de peso e estatura serviram para o cálculo do IMC: peso (kg)/ estatura(m)2, e então se detectou o estado nutricional segundo os pontos de corte estabelecidos pela Organização Mundial da Saúde (OMS). As associações entre o consumo de derivados de trigo e fatores demográficos e estado nutricional foram realizadas por meio de análise estatística, para a qual se utilizou o programa Epi Info versão 7.2.0.1. Os dados foram submetidos ao teste de Mann-Whitney (p<0,05) para se determinar a significância dos resultados. Os resultados demonstraram consumo maior de alimentos do tipo fast food por adultos entre 20 e 30 anos e em quantidades expressivas em todas as faixas de IMC. Identificaram-se como derivados de trigo mais consumidos os de panificação e as massas. Não houve significância estatística ao se comparar peso com ingestão dos derivados de trigo.

“…As Sabaté points out, there are different methods used for the evaluation of food consumption, the 24-hour Reminder being a useful tool for this purpose, the dietary journal allows to detail the quantities of food and beverages consumed [28][29][30]. The dietary history allows us to evaluate the average food and liquid intake as well as the frequency of consumption questionnaire , the latter being the most widely used, being validated in several languages such as Spanish , Chinese , Guam , for multiethnic populations , in Korean , Danish , Japanese , New Zealand , Brazil , Norway , Australia , among others [31,32,25,[33][34][35][36][37][38][39][40][41][42].…”
