Abstract
Background and purpose: An appropriate nutrition throughout the lifespan is important. As adolescent girls nutrition status can affect community health in future. We decide to determine the frequency and composition of food from different groups of foods in adolescent girls of Sari (North of Iran).
Materials and Methods: In the winter of 2004, 240 adolescent girls (14-18 years of age) from Sari high schools were randomly selected and food frequency questionnaires were completed. Also they were asked about their meals and snacks. Data were analyzed using SPSS version 11.5 software and the charts were drown using Microsoft Excel software.
Results: The results indicated that the most consumed foods in groups of meats, dairies, grains and potatoes, vegetables, fruits and junky foods were egg, yoghurt, rice, tomato, citrus and chocolate respectively.

Abstract
Background and purpose: This study was aimed to assess the reliability and reproducibility of a designed food frequency questionnaire (FFQ) and to determine the major dietary pattern of overweight and obese adults in Tabriz, Iran.
Materials and methods: The study included two studies: (1) a pilot study (n = 30) assessment of reliability and reproducibility of FFQ, (2) a cross-sectional study (n = 422) aiming to determine the major dietary pattern of overweight and obese adults. A 189-food item FFQ was completed twice with one-month interval for each subjects. Food consumption over one year for 422 adults aged 20-60 years in Tabriz was collected after assessment of reliability and reproducibility of FFQ. Weight and height were measured and body mass index (BMI) was estimated. Factor analysis was used to determine major dietary pattern.
Results: Correlation coefficient of the two completed FFQ was varied from 0.60 (for garlic) to 0.97 (for potatoes). Three major dietary patterns were found using factor analysis: "healthy", "western" and "traditional" dietary pattern. Correlation coefficient for the three "Healthy", "Western" and "Traditional" dietary patterns, were 0.90, 0.83 and 0.92, respectively. These dietary patterns included 23% of the total variances.
Conclusion: The reliability and reproducibility of the FFQ used in this study was good. There were three major dietary pattern using FFQ among overweight and obese adults in Tabriz.
