    Article - En anglais


    Iodine Deficiency Disorders (IDD) are a major public health problem in India.

    The National Capital Territory (NCT) of Delhi is a known iodine deficiency endemic area.

    The Delhi Government banned the sale of non-iodised salt since 1989.

    The present study was conducted to assess the status of IDD after 7 years of salt iodisation programme in the state.


    Cross sectional.


    The recent indicators recommended by the World Health Organization-United Nations Childrens Fund-International Council for the Control of Iodine Deficiency Disorders (WHO-UNICEF-ICCIDD) were utilized for the assessment of IDD.

    A total of 30 clusters were selected using population proportionate to size cluster sampling procedure.

    In each identified cluster, one primary school was selected using random sampling.

    A total of 6911 school children in the age group of 8-10 years were included for the study.


    The total goiter prevalence rate was 8.6% while 2.1,8.4,17.6 and 71.9% of the children had urinary iodine excretion levels of<2,2 - 4.9,5 - 9.9 and 10 and above mcg/dl, respectively.

    The median urinary iodine excretion was 17 mcg/dl.

    Of the 1854 salt samples analyzed, salt with a nil iodine content was consumed only by 1.4% of the beneficiaries.

    Forty one per cent of families consumed salt with an iodine content of less than 15 ppm.


    IDD continues to be a public health problem in the NCT of Delhi. (...)
