The aim of the study was to asses the relative validity and the reproducibility of a quantitative food frequency questionnaire for epidemiologic studies with adolescents with type 1 diabetes. The participants were 70 adolescents of both sexes, regularly assisted at the endocrinology department of the Hospital das Clínicas from the Universidade Federal de Goiás and of the Hospital Geral de Goiânia. The socioeconomic status, demographic data, metabolic control, antropometry, physical activity and estimated energy requirement were evaluated. The food consupmtion was evaluated by the application of four 24-hour recalls, also used for the validation study. The reproducibility was evaluated by the comparison of the results obtained after two applications of the questionnaire. T test was aplied and Pearson correlation of energy-adjusted data was calculated and than corrected by intra personal variation. Agreement tests were also applied for validation and reproducibility. The adolescents presented an average of 14 years-old and an income of two salaries. More than 80% presented inadequate glycemic control that might be influenced by the caregiver's education and insulinic therapy. The diet was under the recommendations for carbohydrates and with high proportion of lipids. Most of the adolescents were sedentary or practiced light activity. The correlation coefficients obtained from the recalls and the questionnaires were as described by the literature, except for protein, which was inferior. The reproducibility of results showed good agreement. The questionnaire demosntrated acceptable capacity in measuring habitual consumption of adolescents with type 1 diabetes, being recommended as an instrument in clinic and epidemiologic studies with this population.
