“…O primeiro questionário aplicado foi um Questionário de Frequência Alimentar (QFA) modelo adaptado de Motta et al (2021) disponibilizado pela plataforma do Google Formulários, e nele continha diversos tipos de alimentos como os dos grupos: in natura, minimamente processados, processados e ultraprocessados. A parte inicial do QFA constava de perguntas a respeito de dados pessoais e ao final do questionário possuíam outras perguntas relacionadas às práticas alimentares.…”

O ciclismo é um esporte de alto rendimento que possui características de resistência devido aos percursos de longa distância, portanto, são necessários hábitos alimentares adequados para possibilitar que os ciclistas tenham um bom desempenho. O presente trabalho teve como objetivo realizar uma pesquisa de campo com coleta de dados e indicadores que possam trazer uma reflexão sobre o comportamento alimentar de ciclistas e sua composição corporal. Foi realizado um estudo transversal e descritivo com um grupo de ciclistas com idades entre 18 e 60 anos, que treinam com percursos médio de 150 quilômetros por pelo menos duas vezes na semana em estradas do DF. O estudo foi realizado em três etapas, sendo a primeira: aplicação de um questionário através do Google Forms, abordando sobre o consumo alimentar e a utilização de suplementação. A segunda etapa foi feita a medição das dobras cutâneas para avaliação do percentual de gordura total, e posteriormente a análise dos dados. Portanto, através da observação dos resultados foi verificado que há um elevado consumo de alimentos ultraprocessados, e a maior dificuldade relatada pelos ciclistas foi a falta de tempo (29,7%), grande parte deles iniciou a suplementação através da indicação de um nutricionista ou médico (66,7%), porém, muitos ainda suplementam por conta própria, o percentual de gordura corporal da maioria dos ciclistas está dentro do adequado (91,8%). Diante disso, a pesquisa foi útil para incentivar a realização do acompanhamento nutricional, que é essencial para que os ciclistas utilizem estratégias eficazes para aumentar o rendimento.

The Nova system categorizes foods according to processing levels, and dietary intake instruments not developed to assess this criteria may introduce bias in epidemiological studies. To address this gap, we developed and validated the Nova Food Frequency Questionnaire (NovaFFQ) for Brazilian adults. The NovaFFQ includes commonly consumed foods and drinks based on 2017-2018 National Food Survey data. Reproducibility was assessed by comparing NovaFFQ estimates on two occasions. Criterion validity was assessed by comparing the mean dietary contribution of Nova groups obtained from the first NovaFFQ against two Nova24h. Strong reproducibility was observed with an intraclass correlation coefficient (ICC) of 0.91 for all Nova groups. Criterion validity showed a moderate ICC, ranging from 0.61 to 0.65, and substantial agreement in ranking individuals, as indicated by prevalence and bias-adjusted kappa, ranging from 0.70 to 0.74. The NovaFFQ is a valid instrument for assessing food consumption according to food processing.

Background Recent lifestyle changes include increased consumption of highly processed foods (HPF), which has been associated with an increased risk of non-communicable diseases (NCDs). However, nutritional information relies on the estimation of HPF consumption from food-frequency questionnaires (FFQ) that are not explicitly developed for this purpose. We aimed to develop a short screening questionnaire of HPF consumption (sQ-HPF) that integrates criteria from the existing food classification systems. Methods Data from 4400 participants (48.1% female and 51.9% male, 64.9 ± 4.9 years) of the Spanish PREDIMED-Plus (“PREvention with MEDiterranean DIet”) trial were used for this analysis. Items from the FFQ were classified according to four main food processing-based classification systems (NOVA, IARC, IFIC and UNC). Participants were classified into tertiles of HPF consumption according to each system. Using binomial logistic regression, food groups associated with agreement in the highest tertile for at least two classification systems were chosen as items for the questionnaire. ROC analysis was used to determine cut-off points for the frequency of consumption of each item, from which a score was calculated. Internal consistency of the questionnaire was assessed through exploratory factor analysis (EFA) and Cronbach’s analysis, and agreement with the four classifications was assessed with weighted kappa coefficients. Results Regression analysis identified 14 food groups (items) associated with high HPF consumption for at least two classification systems. EFA showed that items were representative contributors of a single underlying factor, the “HPF dietary pattern” (factor loadings around 0.2). We constructed a questionnaire asking about the frequency of consumption of those items. The threshold frequency of consumption was selected using ROC analysis. Comparison of the four classification systems and the sQ-HPF showed a fair to high agreement. Significant changes in lifestyle characteristics were detected across tertiles of the sQ-HPF score. Longitudinal changes in HPF consumption were also detected by the sQ-HPF, concordantly with existing classification systems. Conclusions We developed a practical tool to measure HPF consumption, the sQ-HPF. This may be a valuable instrument to study its relationship with NCDs. Trial registration Retrospectively registered at the International Standard Randomized Controlled Trial Registry (ISRCTN89898870) on July 24, 2014.
