Food frequency questionnaires (FFQ) are important tool in estimating dietary intake in large nutritional epidemiological studies. Hence, this study aimed to develop and validate a food frequency questionnaire to assess the dietary intake of slum children of Varanasi. 10 categories of food with 33 food items were developed based on the food use of the study area. A pilot study was done on 50 slum children of Varanasi. The FFQ was tested for repeatability and validation against 24 hour dietary recall in 50 samples. The results of the validation study demonstrated good acceptance of the FFQ. Mean intake of macronutrients in FFQ1 and 24-h diet recall correlated well. Higher correlations were noted between the two methods in energy (0.60), fat (0.54) and carbohydrate (0.61) and moderate in protein (0.34). Pearson’s correlation is also used to measure reproducibility between FFQ1 and FFQ2. These findings indicate that the FFQ is valid and reliable
