Iodine Deficiency Disorders (IDD) are the leading cause of goiter, cretinism, developmental delays and other health problems. Iodine deficiency is an important public health issue as it is a preventable cause of intellectual disability. While elimination of iodine deficiency is imperative, it should be noted that excessive intake of iodine can also lead to adverse health effects. This paper analyzed the iodine status using median urinary iodine concentration (MUIC) of school age children (SAC), women of reproductive age (WRA), and pregnant women (PW) who live in the same household from Riskesdas 2013. The total number of households included in the analysis was 13,811 households, from which 6,149 SAC (aged 6 – 12 years), 13,218 WRA (aged 15-49 years), and 578 PW (aged 15-49 years) were enumerated. The national MUIC of SAC, WRA and PWwas  in the normal range indicated that  the iodine status was adequate using WHO epidemiological criteria. Iodine status in some sub-populations indicated deficiency, however, in terms of geographic characteristics people who live in the urban has better iodine status compared to rural areas. Similarly, populations in richer economic quintiles had better iodine status. Only pregnant women in the 1st and 2nd quintile were deficient. Almost all regions in Indonesia showed the MUIC was in the normal adequate range, except NTT-NTB, Maluku-Papua, and East Java for pregnant women who tend to have lower MUIC (<150 µg/L). The status of iodized salt at the household was detected using both Rapid Test Kit/RTK as well as Titration. The result demonstrated a strong association between salt iodine level and iodine status. The MUIC for all three groups were lower when the iodine level in salt was lower, then increased when the levels of iodine content in salt increased. The iodine status of pregnant women consuming non-iodized salt was inadequate. The detrimental effect of iodine deficiency on the mental and physical development of children as well as on the women of reproductive age has been recognized. Indonesia still needs the salt iodization program to keep the iodine status in the normal range. In particular coverage with adequately iodized salt needs to be improved in order to improve the iodine status of pregnant women. For the prevention of Iodine disorders (insufficient), monitoring should be undertaken in regular basis to assess the MUIC, especially for pregnant women.

Abstract Objective: Assessment of iodine nutritional status in pregnant women in the perimarine area of Romania, a region without iodine deficiency. Adequate iodine intake is the main source for normal thyroid function, ensuring the need for maternal thyroid hormones during pregnancy, but also for the development and growth of children in the fetal and postpartum period. Material and method: Prospective study performed on 74 pregnant women in the first 2 trimesters of pregnancy, originating from the perimarin area. The following indicators of iodine status were analyzed: urinary iodine concentration (UIC), the ratio between urinary iodine concentration and urinary creatinine (UIC/UCr), the prevalence of maternal goiter and the value of neonatal TSH (thyroid stimulating hormone). Results: The mean gestational age was 11 weeks. The ways of iodine intake are: iodized salt - 59.4%, iodized salt and iodine supplements- 23%, only iodine supplements -10.8% and 6.8% consume only non-iodized salt. The median of UIC was 133.03 mcg/l considered insufficient iodine intake (normal in pregnancy UIC >150 mcg/l), but the adjustment of UIC to urinary creatinine reveals a median of 152.83 mcg/g, a value that reflects an adequate iodine intake. The prevalence of goiter was 25.6% characteristic for a moderate iodine deficiency. The prevalence of neonatal TSH >5 mIU/L was registered in 18.8% characteristic of mild iodine deficiency. Conclusions: Monitoring of the iodine nutritional status is recommended for the prevention of disorders due to iodine deficiency under the conditions of universal salt iodization. Perimarine areas considered sufficient in iodine may show variations in iodine status in subpopulations under certain physiological conditions, such as pregnancy. An indicator of iodine status of the population is UIC, but the UIC/UCr ratio may be a more optimal indicator for pregnant women, to avoid possible overestimated results of iodine deficiency in pregnancy.

Pakistan is considered to be one of the most severely iodine deficient countries in the region. A decade earlier, 70% of the population was estimated to be at risk of iodine deficiency. However, the recent use of iodized salt has reduced the intensity of the problem. Earlier studies regarding iodine deficiency in Pakistan were restricted to the northern mountainous regions, but have now been extended to the sub-Himalaya areas and the plains of Punjab. The aim of the present study was to investigate the prevalence of goiter and iodine status among school children in district Kohat, Pakistan. The 30 cluster approach was adopted for the study. From each cluster, 40 samples were collected from school going children. The palpation method was used to measure goiter grade, whereas, for urinary iodine estimation, the wet digestion method was used. The prevalence of goiter in the district was found to be 35% (37.16% in boys and 33% in girls). The median urinary iodine concentration was found to be 56±31.19?g/L. Estimation of iodine content in salt illustrated that 56.8% people were consuming non-iodized salt and 43.5% were using iodized salt. The current study suggests a severe iodine deficiency in school children of district Kohat and regular iodine supplementation is required on an instant basis.South East Asia Journal of Public Health Vol.4(2) 2014: 42-46

Background. Iodine deficiency causes maternal hypothyroidism which can lead to growth, cognitive, and psychomotor deficit in neonates, infants, and children. This study examined the iodine status of pregnant women in a periurban setting in Ghana. Methods. This longitudinal study recruited 125 pregnant women by purposeful convenience sampling from the antenatal clinic of the Sefwi Wiawso municipal hospital in Ghana. Urinary iodine concentration (UIC) was estimated by the ammonium persulfate method at an estimated gestational age (EGA) of 11, 20, and 32 weeks. Demographic information, iodized salt usage, and other clinical information were collected using a questionnaire. Results. The prevalence of iodine deficiency among the pregnant women was 47.2% at EGA 11 and 60.8% at both EGA of 20 and 32, whereas only 0.8% of participants not using iodized salt had iodine sufficiency at EGA 32. 18.4%, 20%, and 24% of participants using iodized salt had iodine sufficiency at EGA 11, 20, and 32, respectively. Conclusion. A high prevalence of iodine deficiency was observed among our study cohort.

Abstract Objectives Approximately 2 billion individuals suffer from an insufficient iodine intake, and sub-Saharan Africa is particularly the most affected. We thus conducted a cross-sectional study to assess iodine deficiency status, among women of reproductive age 20–49 years in Tanzania and examine the factors associated with iodine deficiency. Methods The current analysis was based on 3057 women aged 20–49 y who participated the Tanzania Demographic and Health Surveys 2015–2016. Iodine status was assessed using urinary iodine concentration (UIC). Iodine deficiency was defined if UIC was less than 100ug/L. A stepwise multivariable logistic regression to identify the factors associated with iodine deficiency. Potential predicators included age, education level, married status, wealth index, having a prenatal doctor and prenatal nurse, currently pregnant, currently breastfeeding, place of residence, employment status, and history of terminated pregnancy. Results The median UIC among pregnant women (median: 129 μg/L; 25th and 75th percentile: 57.8–240), uneducated women (99.0 μg/L; 48.2–201 μg/L), and poor women (92 μg/L; 43.1 -191 μg/L) were below the recommended ranges (≥150 μg/L for pregnant women and ≥100 μg/L for non-pregnant women) by the World Health Organization. Multivariable logistic stepwise regression showed that women were more likely to be iodine deficient if they were pregnant (aOR 1.55 [95% CI 1.11, 2.15], currently breastfeeding (aOR 1.56 [95% CI 1.28, 1.92], poor (aOR 1.75 [95% CI 1.35, 2.26], uneducated (aOR 1.77 [95% CI 1.26, 2.48], and living in the rural area (aOR 1.79 [95% CI 1.37, 2.34]. Unexpectedly, currently employed women also had significantly higher odds of iodine deficient (aOR 1.41 [95% CI 1.10, 1.80], relative to those without employment. Conclusions There is disparity in UIC among of women of reproductive age 20–49 in Tanzania. Poverty and lack of education appeared to be the driving factors for iodine deficiency. High risk of iodine deficient among pregnant and breastfeeding women appeal for action to implement and enforce universal salt iodization among this vulnerable population in Tanzania. Funding Sources There was no external or internal funding to support this study.

Background: Iodine deficiency disorders have continued to be a significant health problem in some Nigerian communities despite universal salt iodization. Objective: This study was designed to assess the iodine status of school age children (6-12 years) in Umuahia South LGA of Abia State, Nigeria. Methods: A total of 414 school children were studied. Urine samples were obtained from 84 school children, 30 males and 54 females. The background and socio-economic information, food habit and dietary intake of the respondents were determined using validated questionnaires. Urinary iodine concentration analysis, using Sandell-Kolthoff reaction was used to determine the iodine status of the children. Chi-square was used to determine the relationship between urinary iodine status of the children and the socio-economic characteristics of their parents. Results: More than half (58.7%) of the children were females while 40.5% were males. About a quarter of the children (40.1%) were 9-10 years, 23.4% were 11-12 years while 36.5% were 6-8 years. Most of the respondents (72.2%) were aware of iodized salt; 14.3% heard about iodized salt from friends, 41.8% heard from the media while 13% heard about iodized salt from the market. Majority of the respondents (94.4%) claimed they consume iodized salt while 4.9% said they use salts that were measured in cups which was not iodized salt. The study revealed that 54.3% of the school children had optimal iodine status while 35.7% had mild iodine deficiency which was higher in males (46.7%) than in females (29.6%). About 5.6% of the respondents had grade 1 goiter. There was a significant association (p< 0.05) between urinary iodine status of the school children and educational status of their fathers’, mothers’, parents’ occupation and income level of fathers. Conclusion: Nutrition education should be aimed at mothers, caregivers, and school children to promote consumption of iodine rich foods.

Background. Despite the measures taken by the Government of Belarus, the problem of iodine deficiency among the population remains actual. Aims. To determine iodine sufficiency in children and pregnant women living in Belarus. Materials and methods. The study included 873 schoolchildren aged 9–12 years of both sexes, of which 650 children were in regular schools, and the remaining children in boarding schools. A separate group consisted of 700 practically healthy pregnant women (during gestation from 16 to 36 weeks). Questioning, determination of urinary iodine concentration and thyroid volume with ultrasound was carried out. Results. Urine iodine median was 191 µg/L in the 873 children in 16 regions of Belarus. Thyroid volume corresponds to the normative values in children. According to the survey, 81% of households used iodized salt, constantly – 46%. Indicator of iodine sufficiency of 700 pregnant women (median urinary iodine concentration was 121 µg /l) is a non-optimal for this population group. Conclusions. Currently adequate iodine supplementation in school age children has been achieved. The prevalence of thyroid gland diseases caused by iodine deficiency in children decreased significantly. In pregnant women iodine supply is still insufficient.

Iodine is an essential micronutrient for cognitive development and growth. Optimal intakes are critical during pregnancy. We report the iodine status and thyroid function of pregnant women living in areas previously affected by severe iodine deficiency and in longstanding iodine sufficient areas in Java, Indonesia. This cross-sectional study was conducted in Magelang, Java, from July to November 2015, in four sub-districts; two previously affected by severe iodine deficiency (area 1) and two that were iodine-sufficient (area 2). Iodine intake was estimated using median urinary iodine concentration in spot samples and mean urinary iodine excretion in 3 x 24-hour samples, thyroid hormones (thyroid-stimulating hormone and free thyroxine) were measured in venous blood samples, and iodine content of household salt samples was estimated by titration. We recruited a total of 244 pregnant women, 123 in area 1 and 121 in area 2. Urinary iodine results suggested adequate habitual iodine intakes in both areas (median urinary iodine concentration in area 1: 222 μg/l (interquartile range 189, 276 μg/l), area 2: 264 μg/l (interquartile range 172, 284 μg/l), however, the risk of inadequate intakes increased with advancing trimester (Odds Ratio = 2.59 (95% CI 1.19–5.67) and 3.85 (95% CI 1.64–9.02) at second and third trimesters, respectively). Estimated prevalence of thyroid function disorders was generally low. Salt was iodized to approximately 40 ppm and foods rich in native iodine did not contribute significantly to dietary intakes. Adequately iodized salt continues to prevent iodine insufficiency in pregnant women living in areas previously affected by severe iodine deficiency in Java, Indonesia. Monitoring and surveillance, particularly in vulnerable groups, should be emphasized to ensure iodine sufficiency prevails.

AbstractObjectiveTo assess iodine status among pregnant women in rural Zinder, Niger and to compare their status with the iodine status of school-aged children from the same households.DesignSeventy-three villages in the catchment area of sixteen health centres were randomly selected to participate in the cross-sectional survey.SettingSalt iodization is mandatory in Niger, requiring 20–60 ppm iodine at the retail level.SubjectsA spot urine sample was collected from randomly selected pregnant women (n662) and one school-aged child from the same household (n373). Urinary iodine concentration (UIC) was assessed as an indicator of iodine status in both groups. Dried blood spots (DBS) were collected from venous blood samples of pregnant women and thyroglobulin (Tg), thyroid-stimulating hormone and total thyroxine were measured. Iodine content of household salt samples (n108) was assessed by titration.ResultsMedian iodine content of salt samples was 5·5 ppm (range 0–41 ppm), 98 % had an iodine content <20 ppm. Median (interquartile range) UIC of pregnant women and school-aged children was 69·0 (38·1–114·3) and 100·9 (61·2–163·2) µg/l, respectively. Although nearly all pregnant women were euthyroid, their median (interquartile range) DBS-Tg was 34·6 (23·9–49·7) µg/l and 38·4 % had DBS-Tg>40 µg/l.ConclusionsIn this region of Niger, most salt is inadequately iodized. UIC in pregnant women indicated iodine deficiency, whereas UIC of school-aged children indicated marginally adequate iodine status. Thus, estimating population iodine status based solely on monitoring of UIC among school-aged children may underestimate the risk of iodine deficiency in pregnant women.

Abstract Milk is the main source of iodine in the UK; however, the consumption and popularity of plant-based milk-alternative drinks are increasing. Consumers may be at risk of iodine deficiency as, unless fortified, milk alternatives have a low iodine concentration. We therefore aimed to compare the iodine intake and status of milk-alternative consumers with that of cows’ milk consumers. We used data from the UK National Diet and Nutrition Survey from years 7 to 9 (2014–2017; before a few manufacturers fortified their milk-alternative drinks with iodine). Data from 4-d food diaries were used to identify consumers of milk-alternative drinks and cows’ milk, along with the estimation of their iodine intake (µg/d) (available for n 3976 adults and children ≥1·5 years). Iodine status was based on urinary iodine concentration (UIC, µg/l) from spot-urine samples (available for n 2845 adults and children ≥4 years). Milk-alternative drinks were consumed by 4·6 % (n 185; n 88 consumed these drinks exclusively). Iodine intake was significantly lower in exclusive consumers of milk alternatives than cows’ milk consumers (94 v. 129 µg/d; P < 0·001). Exclusive consumers of milk alternatives also had a lower median UIC than cows’ milk consumers (79 v. 132 µg/l; P < 0·001) and were classified as iodine deficient by the WHO criterion (median UIC < 100 µg/l), whereas cows’ milk consumers were iodine sufficient. These data show that consumers of unfortified milk-alternative drinks are at risk of iodine deficiency. As a greater number of people consume milk-alternative drinks, it is important that these products are fortified appropriately to provide a similar iodine content to that of cows’ milk.
