AbstractObjectiveThe main objective was to assess iodine status (thyroid volume (Tvol) and urinary iodine concentration (UIC)) and their determinants in Saharawi refugee women.DesignA cross-sectional survey was performed during January–February 2007. Tvol was measured by ultrasound and iodine concentration was analysed in spot urine samples and in household drinking water. Anthropometry and Hb concentration were measured and background variables were collected using pre-coded questionnaires.SettingThe survey was undertaken in four long-term refugee camps in the Algerian desert.SubjectsNon-pregnant women (n 394), 15–45 years old, randomly selected.ResultsMedian (25th percentile–75th percentile (P25–P75)) UIC was 466 (294–725) μg/l. Seventy-four per cent had UIC above 300 μg/l and 46 % above 500 μg/l. Median (P25–P75) Tvol was 9·4 (7·4–12·0) ml and the goitre prevalence was 22 %. UIC was positively associated with iodine in drinking water and negatively associated with breast-feeding, and these two variables explained 28 % of the variation in UIC. The mean (sd) Hb level was 11·8 (2·4) g/dl. In total 46 % were anaemic with 14 %, 25 % and 7 %, classified with respectively mild, moderate and severe anaemia.ConclusionsThe Saharawi women had high UIC, high levels of iodine in drinking water and increased Tvol and probably suffered from iodine-induced goitre. The high prevalence of anaemia is considered to be a severe public health concern. To what extent the excessive iodine intake and the anaemia have affected thyroid function is unknown and should be addressed in future studies.

AbstractObjectiveTo assess the prevalence of enlarged thyroid volume (Tvol) in Saharawi refugee children, and their urinary iodine concentration (UIC), and to identify possible sources of excess iodine intake.DesignA cross-sectional survey was performed during January–February 2007. Tvol was measured by ultrasound and iodine concentration was analysed in casual urine samples, in household drinking water and in milk samples from household livestock.SettingThe study was undertaken in four refugee camps in the Algerian desert.SubjectsThe subjects were 421 Saharawi children, 6–14 years old.ResultsEnlarged Tvol was found in 56 % (Tvol-for-age) and 86 % (Tvol-for-body-surface-area) of the children. The median (25th percentile–75th percentile, P25–P75) UIC was 565 (357–887) μg/l. The median (P25–P75) iodine concentration in household drinking water was 108 (77–297) μg/l. None of the children had UIC below 100 μg/l, 16 % had UIC between 100 and 299 μg/l, and 84 % had UIC above 300 μg/l. There was a positive association between Tvol and whether the household possessed livestock.ConclusionsThe children are suffering from endemic goitre and high UIC caused probably by an excessive intake of iodine. The excessive iodine intakes probably originate from drinking water and milk.

AbstractObjectiveTo identify children's iodine nutrition and goitre status in areas with mildly excessive iodine in drinking water.DesignA cross-sectional survey. Probability proportional to size sampling was employed to randomly select children from thirty townships where the median iodine content in drinking water ranged from 150 to 300 μg/l; their urinary iodine concentrations were determined and their thyroid volumes were measured by ultrasound. Drinking water samples and salt samples from the villages where the children lived were collected using a systematic sampling method.SettingHebei Province of China.SubjectsA total of 1259 children aged 8–10 years (621 boys and 638 girls).ResultsChildren's median urinary iodine concentration was found to be 418·8 μg/l, and the iodine concentration was >300 μg/l for 68·3 % (248/363) of the urine samples. Children's median urinary iodine concentration in villages with median salt iodine >10 mg/kg was significantly higher than that in villages with median salt iodine <5 mg/kg (442·9 μg/l v. 305·4 μg/l, P ≈ 0). The goitre rate of 1259 children examined by ultrasound was 10·96 %.ConclusionsThe iodine intake of children living in areas with mildly excessive iodine in drinking water in Hebei Province was found to be excessive. The measured iodine excess in the sampled children is exacerbated by consumption of iodized salt. Goitre was identified in these areas; however, due to the limitation of the current criteria for children's thyroid volume, a comprehensive assessment of the prevalence of goitre in these regions could not be made and further study is required.

Objective. Iodine deficiency is defined by the goiter and the urinary iodine concentration. However, a lack of local thyroid volume reference data resulted in the vague definition of goiter, especially in school-aged children. The aim of this paper was to determine the thyroid volumes by ultrasonography in schoolchildren aged 6 to 12 years living in Cagayan areas in Philippine.Methods. Cross-sectional thyroid ultrasonographic data of 158 schoolchildren aged 6–12 years from Tuguegarao and Lagum in Cagayan valley, Philippine were used. Thyroid volumes were compared based on logistic issue and urban and rural area and compared with other previously reported data.Results. The mean values of thyroid volume in Tuguerago and Lagum were2.99±1.34 mL and2.42±0.92 mL. The thyroid size was significantly in association with age (P<0.00), weight (P<0.00), height (P<0.00), and BSA (P<0.00) by Pearson’s correlation. The median thyroid volumes of schoolchildren investigated in this study were generally low compared to international reference data by age group but not by BSA.Conclusions. We propose for the first time local reference ultrasound values for thyroid volumes in 6–12 aged schoolchildren that should be used for monitoring iodine deficiency disorders.

Mild to moderate iodine deficiency is common among women of childbearing age. Data on iodine status in infants are sparse, partly due to the challenges in collecting urine. Urinary iodine concentration (UIC) is considered a good marker for recent dietary iodine intake and status in populations. The aim of this study was to investigate the reliability of iodine concentration measured in two spot-samples from the same day of diaper-retrieved infant urine and in their mothers’ breastmilk. We collected urine and breastmilk from a sample of 27 infants and 25 mothers participating in a cross-sectional study at two public healthcare clinics in Norway. The reliability of iodine concentration was assessed by calculating the intraclass correlation coefficients (ICC) and the coefficient of variation (CV). The ICC for infants’ urine was 0.64 (95% confidence interval (CI) 0.36–0.82), while the ICC for breastmilk was 0.83 (95% CI 0.65–0.92) Similarly, the intraindividual CV for UIC was 0.25 and 0.14 for breastmilk iodine concentration (BIC). Compared to standard methods of collecting urine for measuring iodine concentration, the diaper-pad collection method does not substantially affect the reliability of the measurements.

Italy is considered a mildly iodine-deficient country. The aim of this study was to evaluate the iodine status of a cohort of adults living in Liguria after the 2005 salt iodization program. We searched all medical records of patients examined in two endocrine outpatient clinics in Genoa and Savona for data on urinary iodine. Subjects were under evaluation for thyroid diseases. Information on the type of salt used was found in few clinical records. Iodized salt use was reported in 29%, 20%, and 13% of records of people living in Genoa districts, the Savona district and nearby districts, respectively. The average urinary iodine concentration was 112.9 ± 62.3 µg/L (n = 415, median 101.0 µg/L). Non-significant differences (P > 0.05) were found between subjects with (median 103.5 µg/L) and without (median 97.5 µg/L) a thyroid gland, between the periods 2009–2013 (median 105.0 µg/L) and 2014–2018 (median 97.5 µg/L), and between Genoa (median 94.0 µg/L), Savona (median 105.0 µg/L) and the other districts (median 114.5 µg/L). No correlation with age, body mass index, creatinine, free thyroxine, thyroglobulin, levo-thyroxine dosage, or thyroid volume was observed. These data suggest a borderline status of iodine sufficiency in this cohort.

ABSTRACT Background Universal salt iodization (USI) is the most feasible and cost-effective, and equitable, approach to prevent iodine deficiency. Severe maternal iodine deficiency during pregnancy is associated with serious adverse gestational and birth outcomes. Objectives The aim was to assess iodine status and identify independent factors associated with urinary iodine concentration (UIC) among women of reproductive age in Tanzania. Methods This was a weighted, population-based, cross-sectional study in 2985 women of reproductive age (20–49 y) in Tanzania who participated in the Demographic and Health Surveys in 2015–2016 (DHS 2015–2016) and had measured UIC. Multivariable generalized linear regression was used to identify potential factors that were associated with UIC. Results The median UICs among women consuming inadequately iodized salt (93.6 μg/L; 25th and 75th percentiles: 43.1, 197.9 μg/L) and women in the lowest socioeconomic status (92.3 μg/L; 45.6, 194.4 μg/L) were below the WHO-recommended ranges (≥150 μg/L for pregnant women and ≥100 μg/L for nonpregnant women). The results of multivariable models indicated that pregnant women had 1.21 μg/L lower UIC than nonpregnant women (β = −1.21; 95% CI: −3.42, −0.12), breastfeeding women had 1.02 μg/L lower UIC than nonbreastfeeding women (β = −1.02; 95% CI: −2.25, −0.27), and women with no education had a 1.88 μg/L lower UIC compared with those with secondary/highest education (β = −1.88; 95% CI: −4.58, −0.36). Women consuming inadequately iodized salt had 6.55 μg/L lower UIC than those consuming adequately iodized salt (β = −6.55; 95% CI: −9.24, −4.33). The median UIC varied substantially across geographic zones, ranging from 83.2 μg/L (45.9, 165.3) in the Western region to 347.8 μg/L (185.0, 479.8) in the Eastern region. Conclusions Our findings indicated a great heterogeneity in median UIC across regions of Tanzania among women of reproductive age. Poverty, consuming inadequately iodized salt, and lack of education appeared to be the driving factors for lower UIC in Tanzania.

Background. Ear, nose, and throat (ENT) diseases are an oft overlooked global health concern. Despite their high prevalence and associated morbidity and mortality, ENT diseases have remained neglected in health care delivery. In Zambia and many other low-income countries, ENT services are characterized by poor funding, unavailable surgical procedures, and erratic supply of essential drugs. Objective. To investigate ENT service provision in Zambia with regard to availability of surgical procedures and supply of essential drugs. Methods. A descriptive cross-sectional survey was conducted using a piloted structured questionnaire between 17 January 2017 and 2 January 2018. Included in the study were the 109 hospitals registered with the Ministry of Health (MoH) across the 10 provinces of Zambia. Results. Of the participating hospitals, only 5.9% (n=1) and 40% (n=2) of Second-Level Hospitals (SLH) and Third-Level Hospitals (TLH), respectively, carried out tympanoplasty, myringotomy, and grommet insertion (M+G). Frontal trephination and external ethmoidectomy were offered in 11.7% (n=2) and 40% (n=2) of SLH and TLH, respectively. While tracheostomy (39.3%, n=24), tonsillectomy (27.9%, n=17), and adenoidectomy (27.9%, n=17) were the most widely performed head and neck procedures, laryngectomy was carried out by 1 hospital. Between 14.8% (n=9) and 36.1% (n=22) of hospitals lacked antibiotic and/or antiseptic ear drops. Despite 96.7% (n=59) of the respondents acknowledging ENT as an important branch of clinical practice, only 15.3% (n=4) of the hospitals had a budget for ENT. Also, 6.6% (n=4) of the respondents thought the discipline of ENT had received enough attention. Conclusion. ENT service delivery in Zambia is limited with regard to performed surgical procedures and availability of essential drugs, necessitating urgent intervention. The findings from this study may be used to direct national policy on the improvement of provision of ENT services in Zambia.

Objective. Thyroid volume measured by ultrasound to define goiter needs reliable local thyroid volume reference from iodine-sufficient populations. The aim of this study is to explore the reference interval for normal thyroid volume in schoolchildren aged 8–10 years from Zhejiang Province, China.Methods. A probability-proportionate-to-size sampling method was applied to select a representative sample of 1213 children aged 8–10 years in Zhejiang Province to detect the thyroid volume, salt iodine, and urine iodine.Results. Median urinary iodine concentration in involved schoolchildren was 178.30 (125.00) μg l−1, with the percentage of samples less than 100 μg l−1as 12.69% and more than 300 μg l−1as 15.25%. Thyroid volume was significantly correlated with age and anthropometric measurements independently of each other. The 97th percentile of thyroid volume in our study was larger generally than the new international reference.Conclusions. The iodine nutritional status in Zhejiang Province was at an adequate level. Despite some limitations in this study, we initially established the reference values for thyroid volume in 8–10-year-old schoolchildren in Zhejiang Province, China, as a local reference to be used for monitoring iodine deficiency disorders.
