Assessment of iodine deficiency disorders in district Bharatpur, Rajasthan

Iodine deficiency disorders (IDD) is a public health problem in India. A ban on the sale of uniodised salt for household consumption has been introduced in Rajasthan State since 1992. The present study was conducted in the district of Bharatpur, Rajasthan with the objective to assess the prevalence of iodine disorders in school children as no data is available on this aspect. A total of 3072 children in the age group of 6-12 years were included in the study and were clinically examined. On the spot urine samples were collected randomly from 450 children. A total of 1064 salt samples were collected randomly from the families of the children. The total goiter prevalence was found to be 7.2% in the subjects studied. It was found that the percentage of children with urinary iodine excretion <20.0; 20.0-49.9, 50.0-99.9 and 100 mcg/L and above was 1.1, 1.1, 7.8 and 90.0% respectively. The assessment of iodine content of salt revealed that 56% of the families were consuming iodised salt. The findings of the present study indicated that the population is in a transition phase from iodine deficient (as revealed by the TGR) to iodine sufficient (as revealed by the medium UIE of 200.0 mcg/L) nutriture.
