Abstract
The National Capital Territory (NCT) of Delhi was identified as an iodine deficiency endemic area in 1980. The government of NCT of Delhi banned the sale of non-iodised salt since 1989. The present study was aimed to estimate the iodine content of salt consumed in the households of the state. Thirty clusters were selected using population proportionate to size cluster sampling procedure. In each identified cluster one primary school was randomly selected. In each school, 60 salt samples were collected from an equal number of school children. The iodine content of a total of 1854 salt samples collected was analysed using the standard iodometric titration method. Forty one per cent of families consumed salt with an iodine content of less than 15 ppm. Salt with nil iodine content was consumed only by 1.4% of the beneficiaries which indicated successful implementation of universal salt iodisation programme in the state.
