Thyroid status and urinary iodine levels in women of endemic goiter area

ABSTRACT

To determine the thyroid function tests and urinary iodine levels in women belonging to goiter endemic area. Descriptive study conducted in women of goiter endemic area in Saggian Lahore. Saggian Lahore is a goiter endemic area. A total of 293 women between the ages of 18-45 years residing in the area were clinically screened for goiter. Of them 73 women having goiter were recruited for the study. Information regarding demographic profile clinical presentation and physical examination of the goiter was recorded on a questionnaire. The goiter size was graded according to WHO, UNICEF and the International Council for the Control of Iodine Deficiency Disorder. About 5ml of blood sample was drawn from each women and run for thyroid function tests i.e. T3 T4 and TSH using Elisa kits [Human scientific Co. Germany]. Urinary iodine was checked by chemical method. Mean age of 73 women was 28.5 years. Marital status showed that 48[65.7%] were married and 25[34.3%] were unmarried. Visible diffuse goiter was seen in 56[77%] cases. Pressure symptoms as cough and shortness of breath was seen in 30[41%] and 31[42.5%] women respectively. Among the 73 women 24.6% [18 cases] took treatment for goiter. Adverse pregnancy outcome secondary to goiter was seen in 58% [28 cases] out of 48 married women. Thyroid function tests result showed that 72% [53 cases] were euthyroid, 18% [13 cases] were hypothyroid, and 10% [7 cases] were hyperthyroid. Urinary iodine levels showed that 99% women were iodine deficient. Thyroid functions do not indicate iodine deficiency in all cases of goiter, therefore, Urinary iodine levels need be estimated while investigating goiter cases. Policy message Iodine deficiency should be diagnosed and treated on priority basis
