learning objectives
Learning Objectives
  • To study epidemiology of Iodine deficiency disorder.
  • To study how to read a journal article.
  • To study sampling method.
introduction
Introduction
  • Iodine is an essential element for thyroid function, necessary for normal growth, development and functioning of the brain and body.
  • Endemic goiter
  • Mild brain dysfunction, irreversible intellectual impairment.
  • Single most common cause of preventable mental retardation and brain damage in the world today.
objectives
Objectives
  • To assess the magnitude of Iodine Deficiency disorder(IDD) in Jammu region.
  • To assess the salt consumption pattern in the region.
materials and methods
Materials and Methods
  • Study area:- six districts in Jammu :region,Jammu, Udhampur, Kathua, Rajouri, Poonch and Doda
  • Study population:-

School children in age group of 6-12 yrs

  • Study type:- Cross- sectional.
sample size
Sample size
  • The sample size of 768 was estimated expecting goiter prevalence of 40% and accepted error of 5% using the formula
  • Study population was selected using the WHO recommended EPI 30-cluster methodology.
  • A multistage sampling procedure was adopted to select the clusters( school) for the study
sample size cont
Sample size cont…
  • In the first stage, a frame of educational zones in each district was drawn.
  • Using random numbers, five educational zones were selected from each six districts in the region.
  • Thus, a total of 30 educational zones were selected.

  • Finally ,using population proportion to size method, 30 schools(clusters), one from each educational zone, were selected as final sampling unit.
  • A total of 30 students 15Boys & 15 Girls)

from each school were studied after being selected by systematic random sampling.

material method cont
Material & Method cont..
  • A selected children were examined for thyroid enlargement, as recommended by ICMR bulletin 1986.
  • Thyroid enlargement i.e. goiter was graded as
  • G0-No enlargement
  • G1-A Palpable enlargement
  • G2-A visible and palpable enlargement

On spot casual urine sample were collected from 134 of selected subjects in the school.

  • Urine sample were collected in wide mouthed 100 ml plastic bottle
  • Few drops of toluene were added; bottle closed with an inner lid
  • transported under cold condition to laboratory at Dept. of Biochemistry (SKIMS)
  • The urine sample were analyzed by Ammonium Persulphate Method for Urinary Iodine And Result express in ug/l
salt sample analyzed for iodine content
Salt sample analyzed for Iodine Content
  • Study subject were asked about the type of salt consumed at Home
  • 5% of subjects were asked to bring 50g salt from home in polythene pouches for the purpose
  • The Salt were analyzed for iodine content by trimetric analysis & result were expressed as Iodine ppm
results
Results
  • A total of 943 SAC were examined in the region ; in that 113 had goiter giving prevalence of 11.90%
  • No student had grade two goiter
urine analysis results
Urine analysis results:-

Urinary iodine excretion in various district in Jammu region:

discussion1
Discussion:
  • There has been marked improvement in the goiter situation in the region, this could be due to
  • Increase in awareness about benefits of iodized salt
  • Wide availability of iodized salt
  • Improved socio-economic condition of the population with better purchasing power
  • >75% consumes powder salt , 98.5% powder salt having iodine contents > 15ppm
conclusion
Conclusion :
  • The study has shown that the region is in a state of nutritional transition from iodine deficiency to iodine sufficiency, yet complementary should not be allowed to overtake the measure to sustained drive to eliminate the menace.
