Journal Title: National Journal of Integrated Research in Medicine - Year 2011, Vol 2, Issue 4
Abstract
Research Question: What is the situation of iodine deficiency disorder (IDD) and salt consumption in Bhavnagar district? Hypothesis: The prevalence of IDD has increased markedly as a result of medical as well as socio-economic factors. Objective: To assess the magnitude of IDD in Bhavnagar district and also assess the salt consumption patterns in the region. Design: Crosssectional study. Setting: Primary schools in rural areas. Study Tools: Clinical examination of study population for goitre, laboratory assessment of casual urine sample for urinary iodine estimation of I2 content of salt samples collected from sub-samples of study population. Participants: Study was conducted among 2,940 School children in the age group of 6-12 years were selected for study using WHO 30-cluster methodology, urine samples were collected from 15% of selected children and salt samples from 43% of sub-sample. Ethical Concern: No ethical issues were involved. Results: An overall goitre prevalence of 34.19% was observed in the region. Females had a prevalence of 32.9% and males 35.4%. The median urinary iodine excretion in the region was 11.0 μg/l (range: 29.0-190.0 μg/l). Ninty-seven percent of subjects had biochemical iodine deficiency with 73.87% having severe deficiency, 21.38% having moderate and 4.04% mild iodine deficiency. In Bhavnagar region, only 34.27% households consume powdered salt having an Iodine content of greater than 15 ppm. Conclusion: Present study showed severe goiter prevalence in primary school children in Bhavnagar district
