Resumo:
Analisou-se a aplicabilidade de pergunta simplificada na avaliação da qualidade da alimentação de adolescentes em estudo transversal de base escolar, com estudantes do ensino médio. A autopercepção da qualidade da alimentação foi obtida ao inquirir o participante se considerava sua alimentação muito boa, boa, regular ou ruim. Foram avaliados os hábitos de refeições e o consumo alimentar por meio de questionário de frequência de consumo. Estimou-se o Índice de Qualidade da Dieta–Revisado (IQD-R) e foram identificados três padrões alimentares com o uso de análise fatorial. A autopercepção da qualidade da alimentação como “boa” foi referida por 56% dos adolescentes, associando-se ao consumo regular de frutas, hortaliças, das refeições principais e escores elevados do IQD-R. Contudo, o consumo de alimentos deletérios à saúde não foi percebido como característica que afeta a qualidade da dieta. A pergunta avaliada apresentou sensibilidade de 28% para detectar dietas de boa qualidade e especificidade de 79% para identificar dietas de baixa qualidade nutricional, considerando o IQD-R como referência. A utilização de pergunta simplificada para avaliar hábitos alimentares de adolescentes é limitada, dado que o consumo de alimentos com alto teor de gordura, açúcar e sódio não foi reconhecido como indicador de dieta de baixa qualidade.

Abstract:
This study aims to analyze the applicability of a simplified question in assessing diet quality of adolescents. A cross-sectional school-based study was carried out in a random sample of high school students. Self-perception of diet was obtained when the participant was inquired about their diet considering very good, good, fair or poor. It was evaluated the meals habits and food intake through food frequency questionnaire. The revised version of the Brazilian Healthy Eating Index (BHEI-R) was estimated and it was identified three dietary patterns using factor analysis. Self-perceived diet quality as \"good\" was reported by 56% of adolescents and was associated with regular consumption of fruits and vegetables, regular habits of meals consumption, increased healthy eating index scores. However, consumption of harmful foods to health was not perceived as characteristic that affects the quality of the diet. The evaluated question showed sensitivity of 28% to detect good quality diets and specificity of 79% to identify low nutritional value diets, considering the BHEI-R as a reference. The use of simplified question to assess dietary habits of adolescents is limited, since the consumption of foods high in fat, sugar and sodium was not recognized as an indicator of low quality diet.
