Abstract

Background: The assessment of dietary intake in epidemiological studies is often by means of validated FOOD FREQUENCY QUESTIONNAIREs because of ease of administration and low burden on the subject.Method: Study Participants were chosen from five major cities of Iran and 156 subjects, aged 20-69 years old, from both gender were recruited for the study.For VALIDATION study, dietary intake was assessed by a semi-quantitative FFQ, which consisted of 160 Iranian food items. Participants were asked to complete two FFQs (at the first and fourth month of the study) and 3- day food records every month. Two blood and 24-h urine samples were collected at fifth and sixth months for comparison serum and urine concentrations of biomarkers with nutrient intakes estimated by the FFQ.Results: Forty nine persons (32.1 percent) of the subjects were men and 104 persons (67.9 percent) were women The highest correlation coefficient in all FFQs was for fiber (r=0.677; p<0.001) and the lowest one was for fat (r=0.331; p=0.001).The highest correlation coefficient was for potassium Conclusion: The results showed reasonable validity just for carbohydrate intake evaluation and good reproducibility of the FFQ over a 6- month period.
