A population of adult residents of the Stupino district in the Moscow region is examined. Urinary iodine excretion was measured, the thyroid examined by the ultrasonic method and by palpation, and serum TTH measured. Moderate decrease of iodine excretion with the urine (median iodine level in the urine was 91.7%) \ig/liter) indicates a slight iodine deficiency. Palpation revealed enlargement of the thyroid, which was confirmed by ultrasonic examination only in 25%) cases. The highest percentage of disagreements was observed only in first-degree enlargement, the least in third-degree enlargement according to О. V. Nikolaev ’s classification. As for the types of ultrasonic structure of the gland determined by the ratio of its linear parameters (flat, triangular, and cone-like), the highest percentage of disagreements was observed in cases with the flat structure, which is the most incident (77.3%)). Subclinical hypothyrosis was detected in 3%o subjects with iodine deficiency. Only 26%) residents of the examined region regularly consume iodinated salt with food.

It is well established that iodine supplementation is effective in correcting iodine deficiency and reducing goiter prevalence. In Italy, legislation has allowed the production of iodized salt since 1972, but its consumption is on a voluntary basis. In the present study, the efficacy of legislative measures that made compulsory the availability of iodized salt in foodstores has been evaluated. Urinary iodine excretion and thyroid size, scored according to Pan American Health Organization recommendations, were determined prior to (1981) and 10 years after (1991) the introduction of legislative measures in the whole schoolchildren population residing in a restricted area of the Tuscan Appennines. Moreover, in 1991, thyroid volume was determined by ultrasonography. In 1981, mean urinary iodine excretion was 47.1±22.4 mg/kg creatinine (0.412 μmol/l) and goiter prevalence was 60%, indicating a moderate iodine deficiency. Eighty of the families subsequently used iodized salt on a regular basis; as a result of this excellent compliance, in 1991 the mean urinary iodine excretion increased to 129.7±73 mg/kg creatinine (1.24 μmol/l) and goiter prevalence dropped to 8.1%. The results of this study underline the effectiveness of iodine prophylaxis in correcting iodine deficiency and abating endemic goiter in schoolchildren, and suggest that implementation of measures that make compulsory the availability of iodized salt in foodstores overcomes the fact that there is no law governing the exclusive production and trading of iodized salt.

Abstract Aim Iodine deficiency disorder (IDD) is the cause of preventable brain damage, mental retardation, and stunted growth and development in children. This study aimed to detect the prevalence of IDD in Kachchh district, Gujarat, by testing urinary iodine excretion levels and iodine intake of salts in school-going children. Methods A cross-sectional study was conducted and the level of iodine deficiency was assessed in 223 school children of both sexes, aged 6 to 12 years from four talukas, that is, subdivisions, of the Kachchh district by estimating urinary iodine using Sandell–Kolthoff reaction along with iodine content in edible salt samples by MBI kit (STK-Spot testing kit, MBI Kits International, Chennai, TN, India). Results The median urinary iodine level was found to be 194 μg/L, indicating no biochemical iodine deficiency in the region. In the study areas, 1% of the population showed a level of urinary iodine excretion < 50 μg/L. About 83% salt samples had iodine level more than 15 ppm and the iodine content in salt samples less than 15 ppm was only about 17%, indicating the salt samples at households contain iodine in adequate level. Conclusion There is a need of periodic surveys to assess the change in magnitude of IDD with respect to impact of iodized salt intervention.Furthermore, to strengthen National Iodine Deficiency Disorders Control Program, factors should be identified. There is also a need to prevent and reimpose the ban on the sale of noniodized salts in Gujarat.

ISSN 0804–4643 During pregnancy complex changes of maternal thyroid function occur and they are influenced by the maternal iodine supply. It has been demonstrated that with decreasing iodine supply maternal goiter and hypothyroxinemia as well as fetal and neonatal hypothyroidism become more prevalent. Therefore iodine supplementation during pregnancy is now strongly recommended also in areas of moderate iodine deficiency. To monitor the success of iodine supplementation and its theoretical risk of increasing the frequency of thyroid autoantibodies, we have investigated the thyroid volume, thyroid function, urinary iodine excretion and antibodies to thyroid peroxidase at 10–12 weeks of gestation and postpartum in 38 mothers receiving 300 μg potassium iodide/day and in 70 mothers without iodine supplementation. In all of their newborns thyroid volume was determined by ultrasound. The thyrotropin (TSH) levels and antibodies to thyroid peroxidase (TPO-ab) in the neonates were measured in dried blood spots on filter paper from their newborn screening. Urinary iodine excretion was increased significantly after iodine supplementation in mothers (p < 0.001) and their newborns (<0.05). No hypo- or hyperthyroidism was observed in the mothers or newborns. Interestingly, no difference of maternal thyroid volumes was observed between the two groups after pregnancy, but the volumes of the thyroid glands in newborns of mothers who received iodine were significantly (p < 0.004) lower (0.7 ± 0.4 ml) than in the control group (1.5 ± 1.1 ml). There was no change in the frequency of TPO-ab in either group after pregnancy. In four mothers transplacental passage of these antibodies was documented by positive measurement in the blood sample of the newborn. This study documents that iodine supplementation during pregnancy in an area of moderate iodine deficiency results in a lower size of neonatal thyroid volume and that this supplementation was not accompanied by an increase in the frequency of TPO-ab.

Iodine deficiency disorders (IDD) are considered a major health problem in the eastern Mediterranean region. In Jordan, an IDD assessment was performed in 1993 following which, a salt iodization and consumption program was implemented and a monitoring survey performed in 2000. In schoolchildren 8 to 10 years of age (2457 in 1993 and 2601 in 2000) goiter was graded according to WHO classification. Urinary iodine was measured in 10% of the children in 1993 and in all of them in 2000. Percent of iodine consumption in households was assessed by rapid kit test in 2000. Prevalence of goiter was 37.7 and 32.1% and median urinary iodine was 40 and 154 mug/L, in 1993 and 2000, respectively. Before salt iodization, the prevalence of goiter and severity of iodine deficiency was more pronounced in rural regions and in the southern part of Jordan. In 2000, all but one governorate had a median urinary iodine (MUI) of above 100 mug/L. The percentage of urinary iodine levels < 50 mug in two governorates was > 20%. Iodine consumption rate of households was 88.3% throughout the country, but was < 70% in three governorates. It is concluded that moderate and severe IDD existed before 1993 in Jordan. Although the iodized salt program has been successful in optimizing MUI, the program for the control of IDD needs further improvement.

Casual urine samples were collected to determine iodine excretion of 1680 Belarus children during 1990–1994. The subjects, 8–16 years old, were from nine different regions of Belarus; 60% were from the Gomel oblast, which has been associated with relatively high levels of radioiodine fallout and increased incidence of thyroid cancer. Most of the median values indicate borderline/low iodine intake or mild iodine deficiency. Ranges were wide but 163 children excreted < 20 μgI/l urine and they should be considered severely deficient in iodine.

Baltisberger BL, Minder CE, Bürgi H. Decrease of incidence of toxic nodular goitre in a region of Switzerland after full correction of mild iodine deficiency. Eur J Endocrinol 1995;132:546–9. ISSN 0804–4643 In 1980 the iodide content of salt was increased in Switzerland from 7.5 to 15 mg/kg. This raised the mean urinary iodine excretion from 90 (indicating mild iodine deficiency) to 150 μg/g creatinine. We examined whether this public health measure was followed by a change of the incidence of hyperthyroidism in a defined catchment area of 109 000 persons. Except for a 27% rise in the first year of the new salt, the total incidence of hyperthyroidism declined steadily to reach 44% of the control level in 1988/89. This was due to a decrease mostly of toxic nodular goitre (minus 73%), less so of Graves' disease (minus 33%). We conclude that correction of mild iodine deficiency has beneficial effects on the incidence of hyperthyroidism, contrary to what is seen initially after correction of severe deficiency.

Background: Iodine is an essential micronutrient required for normal human growth and development as it is needed for the synthesis of thyroid hormones produced by thyroid glands. The sicknesses occurred due to deficiencies of iodine in the nutrition are termed iodine deficiency disorders. Urinary iodine concentration is the prime indicator of a person’s nutritional iodine status. So, the aim of this study was to assess the status of iodine deficiency based on median urinary iodine excretion.Methods: Community based cross sectional study was carried out among purposively selected primary schools of the Dang district. All students between the age group of 6 to 12 years who were present on the day of visit were included in the study. A total 387 urine samples were collected during the period of August 2015 to September 2016.Results: Based on median urinary iodine excretion, among total analysed samples, about 6.5% samples confirmed severe iodine deficiency, 22% samples showed moderate iodine deficiency and about 36% samples indicated mild iodine deficiency. About one third (31.3%) samples suggested optimum iodine intake. Only few samples (4.4%) revealed more than required iodine intake.Conclusions: About one third (31.3%) of the surveyed population had adequate iodine intake while majority (64.4%) of them had inadequate iodine intake.

 Pregnant women and infants are risk populations of iodine deficiency disorders (IDD). Therefore, this study was designed to explore the status of IDD among pregnant women through the analysis of urinary iodine excretion (UIE). A total of 94 pregnant women from Chautara Hospital Sindhupalchowk were included to analyze UIE through Sandell-Kolthoff Reaction. Although the general clinical status of women was satisfactory, the urinary iodine excretion revealed that still, 18.0 percent of pregnant women in Sindhupalchowk had insufficient iodine intake. This indicates that pregnant women are still at risk of iodine deficiency disorder, and they should be in the priority population for the IDD prevention program.

In 1992, the Mongolian government conducted a nationwide palpation study of the thyroid glands, and the study showed an overall goiter rate of 30%. As a result of this, the Mongolian Government launched its Iodine Deficiency Disorders (IDD) Elimination Programme in 1996 and its primary strategy was salt iodization. In 1998 and 1999, we carried out programme monitoring studies in 11 provinces. The results showed: among schoolchildren, a goiter rate was 22.8% (n=6,535), median values of urinary iodine excretion ranged from 11 μg/l to 256 μg/l (n=1,930), and usage rates of iodized salt (>20 PPM iodine content) in their households ranged from 3% to 82%. We concluded that severe iodine deficiency in 1992 was improved from moderate to mild severity a few years later by salt iodization. However, stronger official commitments and community participation are needed to improve the programme so that iodized salt will be made more widely available.

ABSTRACTBackgroundIodine is an essential micronutrient for intellectual development in children. Information on iodine intakes based on 24-h urinary iodine excretion (UIE) is scant, because iodine status is only assessed by the measurement of urinary iodine concentration (UIC) in spot urine samples.ObjectivesThe aim of our study was to evaluate the iodine intake of school-age children and adolescents, using UIE measurement in 24-h urine collections.MethodsThe study population included 1270 healthy subjects (677 boys, 593 girls) aged 6–18 y (mean age ± SD: 10.3 ± 2.9) from 10 Italian regions. Daily iodine intake was estimated as UIE/0.92, based on the notion that $\sim$92% of the dietary iodine intake is absorbed. The adequacy of intakes was assessed according to the Dietary Reference Values for iodine of the European Food Safety Authority (EFSA). Body mass index (BMI) and UIC were also measured for each subject.ResultsBased on the scientific opinion of EFSA, 600 of 1270 subjects (47.2%) had a lower than adequate iodine intake, with a higher prevalence among girls (54.6%) compared with boys (40.2%) (P < 0.001). Although UIE and 24-h urinary volumes increased with age (P < 0.001), a progressive decrease in the percentage of subjects with iodine excretion <100 µg/24 h (P < 0.001) was observed, without any significant difference in the percentage of subjects with UIC <100 µg/L. No significant association was detected between BMI z-score and UIE (P = 0.603) or UIC (P = 0.869).ConclusionsA sizable proportion of our population, especially girls, appeared to be at risk of iodine inadequacy. The simple measurement of UIC could lead to underestimation of the occurrence of iodine deficiency in younger children, because of the age-related smaller urine volumes producing spuriously higher iodine concentrations.
