  Deficiency of iodine causes a wide spectrum of disabilities including the implications on reproductive functions and lowering of IQ levels in school age children. The present study was conducted to assess the status of iodine nutriture and salt iodization in the entire Union Territory of Pondicherry, India. The study was conducted in all the four districts of Pondicherry. In each district 150 salt samples were collected by utilizing the uniform sampling methodology. The iodine content of salt samples was analyzed using the standard iodometric titration method. On the spot casual urine samples were collected from at least 80 children from the same school selected randomly The urinary iodine excretion (UIE) levels were analyzed using the wet digestion method It was observed that 59.7% of the families were consuming iodized salt with more than 5 ppm . It was found that 3 out of 4 districts had adequate iodine nutriture (median UIE levels more than 100 μg/l) possibly due to consumption of iodized salt by majority of the population. This study revealed the success of the salt iodization program in Pondicherry. However, there is a need for strengthening the existing monitoring and distribution system to ensure that adequately iodized salt is available for human consumption to eliminate IDD from the state.

  The food frequency questionnaire (FFQ) method is utilized as a tool in epidemiological studies in which evidence is sought for an association of diet in etiology of a disease. Limited studies have been undertaken to assess the reproducibility of the FFQ methodology in Indian situation. The present study was conducted in an urban middle-income population of Delhi, India. The data on pattern of consumption of food items in standard food groups was collected from 169 subjects, utilizing a pre-tested semi-structured FFQ (Phase I). The consumption pattern of food items in the major food groups was also assessed prospectively for 7 days by the 24-hr dietary recall methodology in each subject. The data was collected again utilizing the similar methodology and tools from the same study subjects after 12 months (Phase II). Reproducibility and validity of the FFQ was assessed by calculating percent agreement between data of Phase I and Phase II utilizing statistical tests. Results revealed that there was a perfect agreement (100% agreement) for the food group i) cereals, ii) fats and oils, and iii) sugar and jaggery. A very good agreement (75-100%) for the food groups i) pulses, ii) green leafy vegetables, iii) fruits, iv) milk products, v) eggs, and vi) flesh foods. Only a good agreement (50 – 75%) was found for the food groups i) roots and tubers, ii) other vegetables, and iii) milk. None of the food groups had fair or poor agreement between the Phase I and Phase II.

  The present study was conducted amongst 212 subjects to assess the reproducibility and validity of the food frequency questionnaire (FFQ) methodology in a rural area of India. The findings of the present study revealed that FFQ for all the food groups is reproducible. A good validity was found between the two methodologies for all the food groups except for pulses.
