Abstract
Background Iodine deficiency remains a public health problem in the world. It is the leading cause of preventable mental retardation and brain damage worldwide. Though 12 million school age children are at risk of developing iodine deficiency, there is a scarcity of literature showing the magnitude of iodine deficiency in Ethiopia. Therefore, this study aimed to determine the prevalence and associated factors of iodine deficiency among school children in Robe District, southeast Ethiopia. Methods A school based cross–sectional study was conducted from February to June, 2015. A structured interviewer-administered questionnaire was used to collect data. A systematic random sampling technique was employed to select 422 children. A multivariate logistic regression analysis was carried out to identify factors associated with iodine deficiency. In the multivariate analysis, variables with a P-value of <0.05 were considered statistically significant. Results A total of 393 school children participated in the study. The median urinary iodine level was 78 μg/l. About 57 and 43.5 % of the children were found with low urinary iodine level and goiter, respectively. Only 29 % of the households utilized adequately iodized salt. The result of the multivariate analysis revealed that the odds of iodine deficiency were higher among female [AOR = 2.23; 95 % CI: 1.54, 3.55] and older (10–12 years) [AOR = 2.21; 95 % CI: 1.44, 3.42] children. Conclusion In this community, the prevalence of goiter and low urine iodine level is high. Thus, iodine deficiency exists as severe public health problem. In addition, there is a low utilization of iodized salt in the setting. Therefore, it is crucial to intensify efforts in the implementation of iodized salt. Moreover, attention should be given to school children to address ID.

Abstract
BACKGROUND Iodine-deficiency disorders are a major public health problem all over the world. Goiter is the most visible manifestation of iodine-deficiency disorder. Goiter rate is useful to assess the long-term impact of iodine-deficiency disorders. OBJECTIVE To determine the risk factors for goiter in primary schoolchildren in southern Ethiopia. METHODS A cross-sectional study on a sample population of 270 children 6 to 12 years of age with goiter and 264 without goiter was conducted in a primary school in Sodo Town, southern Ethiopia. All students in each class were examined for the presence of goiter and classified based on World Health Organization criteria. For each child with goiter, the next child without goiter was selected from the same class. Multivariate logistic regression analysis was employed to determine the effect of independent variables on the goiter rate. RESULTS A total of 534 participants (270 children with goiter and 264 without goiter) were included. Although the difference was not significant, the prevalence of goiter was higher among girls than among boys (54.8% vs. 45.2%), and the prevalence in both sexes increased with age. In the multivariate logistic regression model, consuming common goitrogenic foods (adjusted OR, 1.9; 95% CI, 1.2 to 2.9) and drinking water from the river (adjusted OR, 2.5; 95% CI, 1.2 to 4.9) were independently associated with goiter. CONCLUSIONS Goiter rate is significantly associated with consumption of goitrogenic food items in the area and contaminated drinking water. Creating awareness in the community about the consumption of food items and provision of tap water by concerned bodies in the area is recommended to prevent iodine-deficiency disorders.

Abstract
OBJECTIVE The present study aimed to assess the effect of iodine deficiency on academic achievement of schoolchildren in Wolaita Sodo town, Southern Ethiopia. DESIGN School-based comparative cross-sectional study. SETTINGS Primary school in Sodo town, Southern Ethiopia. SUBJECTS A sample population of 270 children with goitre and 264 without goitre. All students in each class were examined for the presence of goitre and classified based on WHO recommendations. RESULTS Among children with goitre, a higher proportion (54·8 %) was female and the proportion increased with age. The odds of scoring low on school performance was higher among children whose fathers were illiterate (adjusted OR = 1·9; 95 % CI 1·1, 3·5) and those who were absent for more than 5 d in the last academic year (adjusted OR = 1·5; 95 % CI 1·1, 2·3). Goitre was significantly associated with low academic achievement (adjusted OR = 1·8; 95 % CI 1·2, 2·5). CONCLUSIONS The study showed that the presence of goitre has a negative effect on academic achievement even after accounting for parental education and absenteeism from school. Awareness of endemic goitre and its impact on school performance, and an emphasis on prevention and control by concerned bodies, are recommended to alleviate the problem.

Abstract
OBJECTIVE To estimate the prevalence of chronic health and nutritional conditions of schoolchildren in Ethiopia. METHODS Cross-sectional survey in schools in each region randomly selected in proportion to size, then a random sample of 50-68 children in grades 3 and 4 in each school. Children were examined for signs of micronutrient deficiencies and chronic infections; weighed and measured; provided a faecal sample to diagnose intestinal parasitic infections; and were interviewed about their recent diet and hygiene practices. RESULTS A total of 7572 children were studied in 142 schools in all 11 regions of Ethiopia. Nearly 17% of children were orphans. The prevalence of stunting was 22.3% and 23.1% of children were thin for age, but these may be underestimates as there was evidence that age may have been estimated based on stature when children enroll in school. Just under 10% of children were anaemic when altitude was accounted for. The overall prevalence of trachoma was 13% and children who washed their face before school were at lower risk of trachoma than children who had not. Children who reported that they had eaten fruits or vegetables the day before also had a lower risk of xerophthalmia than children who had not. Only 30% of children were infected with intestinal worms. CONCLUSIONS Trachoma is a problem but anaemia and intestinal worms are relatively uncommon in Ethiopian schoolchildren. These data provide a basis for developing a school health policy and programmes.

Abstract
BACKGROUND Iodine-deficiency disorders are a major public health problem in Ethiopia. In conjunction with implementing control programs, baseline information needs to be established. OBJECTIVE To investigate the distribution and degree of severity of iodine-deficiency disorders in terms of goiter prevalence, urinary iodine excretion (UIE) levels, and proportion of households with iodated salt in Ethiopia. METHODS A nationwide, community-based, cross-sectional study was conducted from February to May 2005 among 10,965 children aged 6 to 12 years. A multistage, proportional-to-population-size sampling method was used. Goiters were classified by the method recommended by the World Health Organization/UNICEF/International Council for the Control of Iodine Deficiency Disorders (WHO/UNICEF/ICCIDD), in which the thyroid gland is graded as 0 (normal), 1 (palpable goiter), or 2 (visible goiter); urinary iodine was determined by the wet digestion method; and salt samples were analyzed by a rapid test kit. RESULTS The national total goiter weighted prevalence rate among children aged 6 to 12 years was 39.9% (95% confidence interval, 38.6% to 41.2%), representing more than 4 million children. The median UIE was 2.45 microg/ dL; 45.8% of children had UIE values of 2 microg/dL or less, and 22.8% had UIE values of 2.01 to 5.0 pg/dL. Only 4.2% of the households had iodated salt. CONCLUSIONS According to the WHO/UNICEF/ ICCIDD classification, both goiter prevalence and UIE levels indicate that the whole country appears to be severely affected by iodine deficiency. Furthermore, the virtual absence of iodated salt in the households shows that currently there is no salt iodization program in the country. Dietary sources of iodine in Ethiopia are not dependable, and hence a sustainable universal salt iodization program needs to be implemented without delay.

Abstract
BACKGROUND Iodine deficiency is severe public health problem in Ethiopia. Although urinary iodine excretion level (UIE) is a better indicator for IDD the goitre rate is commonly used to mark the public health significance. The range of ill effect of IDD is however beyond goitre in Ethiopia. In this study the prevalence of goitre and its association with reproductive failure, and the knowledge of women on Iodine Deficiency were investigated. METHODS A cross-section community based study was conducted during February to May 2005 in 10998 women in child bearing age of 15 to 49 years. To assess the state of iodine deficiency in Ethiopia, a multistage "Proportional to Population Size" (PPS) sampling methods was used, and WHO/UNICEF/ICCIDD recommended method for goitre classification. RESULTS Total goitre prevalence (weighted) was 35.8% (95% CI 34.5-37.1), 24.3% palpable and 11.5% visible goitre. This demonstrates that more than 6 million women were affected by goitre. Goitre prevalence in four regional states namely Southern Nation Nationalities and People (SNNP), Oromia, Bebshandul-Gumuz and Tigray was greater than 30%, an indication of severe iodine deficiency. In the rest of the regions except Gambella, the IDD situation was mild to moderate. According to WHO/UNICEF/ICCIDD this is a lucid indication that IDD is a major public health problem in Ethiopia. Women with goitre experience more pregnancy failure (X2 = 16.5, p < 0.001; OR = 1.26, 1.12 < OR < 1.41) than non goitrous women. Similarly reproductive failure in high goitre endemic areas was significantly higher (X2 = 67.52; p < 0.001) than in low. More than 90% of child bearing age women didn't know the cause of iodine deficiency and the importance of iodated salt. CONCLUSION Ethiopia is at risk of iodine deficiency disorders. The findings presented in this report emphasis on a sustainable iodine intervention program targeted at population particularly reproductive age women. Nutrition education along with Universal Salt Iodization program and iodized oil capsule distribution in some peripheries where iodine deficiency is severe is urgently required.

Abstract
The contribution of various factors to malnutrition, particularly stunting, may differ among areas and communities. This cross-sectional study aimed to estimate the level of malnutrition and identify factors associated with the high level of stunting in breast-fed infants aged 5-11 mo living in Dodota-Sire District, Ethiopia. Infants (n = 305) and their mothers were examined physically, and anthropometric and demographic data were collected. The content of zinc, calcium and copper in breast milk was measured, and data collected on the type, frequency of consumption, and time of introduction of supplementary feeding. Overall, 36% were stunted, 41% underweight and 13% wasted. The highest prevalence of malnutrition was seen in infants aged 9-11 mo. Among mothers, 27% had chronic energy deficiency (body mass index, <18.5 kg/m(2)) and 20% were night blind, indicating that vitamin A deficiency was a serious problem. Infants fed >3 times/d, consuming >600 mL/d or consuming cow's milk in addition to cereals and/or legumes had markedly higher length-for-age Z-scores than their peers fed less frequently, consuming less food or not consuming cow's milk [differences: 0.39, 95% confidence interval (CI): 0.04-0.74; 0.17, 95% CI: 0.02-0.32; 0.40, 95% CI: 0.07-0.72, respectively). Infants of mothers with low concentrations of zinc in their breast milk were more stunted. In conclusion, the quality and quantity of foods consumed by infants is insufficient to prevent stunting. Thus it is necessary to increase the nutrient supply to infants by increasing intake and nutrient concentration of breast milk and of supplementary foods they consume, and by providing supplements to infants where appropriate.

Abstract
Survey data are presented from a nationwide survey of the health of schoolchildren in Chad. The country was stratified into distinct ecological zones based on satellite sensor environmental data. Twenty schools were visited and 1024 children aged between 6 and 15 years were included in the study. The overall prevalence of stunting, underweight, anaemia and goitre was 18.7, 16.5, 25.1 and 23.3%, respectively. Schistosoma haematobium, Schistosoma mansoni and hookworm were the only helminth species found with prevalences of 13.2, 1 and 32.7%, respectively. A greater proportion of boys were stunted, underweight, anaemic and infected with S. haematobium and hookworm than girls. Older children were more stunted, underweight and infected with S. haematobium and hookworm than younger children, but less anaemic. The prevalence of infection showed marked geographical heterogeneity, with hookworm prevalence being highest in the Sudanian and tropical zone, and S. haematobium being most prevalent in the Sahelian zone and the Logone and Chari basins in the west of the country. These data show that there is a high prevalence of helminth infection in Chad, but that treatment for S. haematobium and hookworm should be targeted to different geographical areas.

Abstract
A nationwide sample survey was conducted in Chad to establish the prevalence of iodine deficiency disorders (IDD). The country was stratified into the Sahel zone and the Sudan zone, the latter including the city of N'Djamena. The analysis followed a stratification whereby the city of N'Djamena was also separately analysed. A total of 1171 people between 10 and 20 years of age were included in the survey. The overall weighted prevalence of goitre, evaluated by a clinical examination, was 63%. In the Sudan zone the prevalence was 70%, in the Sahel zone 64% and for the capital, N'Djamena, 25%. There were significant differences in the frequency of goitre between the three zones. Females-as established in surveys from other areas and countries-had goitre significantly more often. The prevalence of cretinism varied between 0 and 1.2%, and was highest in the Sahel zone. Amongst the sampled population of the Sudan zone, 33% had less than 20 micrograms/l of urinary iodine, indicating severe iodine deficiency. In the Sahel zone and in N'Djamena the figures reached 8 and 1%. There were high levels of thiocyanate anions in urine reaching medians between 21 and 27 mg/l in the geographical stratas. This probably decreases the bio-availability of iodine. These data show that there is a high endemicity of goitre in Chad and provide a basis for interventions as part of a national action plan against IDD, which will be adapted to the social, cultural and economic situation of the country and to available health services.

Abstract
A total of 14,740 schoolchildren in seven provinces of Shoa Administrative Region in Central Ethiopia were surveyed for the prevalence of goitre, xerophthalmia and anaemia. Haemoglobin and packed cell volume were assessed in 966 children in one province while an in-depth study was conducted on 344 children in the same province and two others. Goitre, xerophthalmia (Bitot's spots) and clinical anaemia were observed in 34.2, 0.91 and 18.6% respectively of the children. Most biochemical variables were within the normal range while those of haemoglobin (Hb), mean corpuscular Hb concentration (MCHC) and urinary I excretion were lower, and mean corpuscular volume, mean corpuscular Hb (MCH), and immunoglobulins G and M were higher. Hb was strongly correlated with retinol, ferritin, MCHC, MCH, packed cell volume and erythrocyte count while retinol formed a triad with transthyretin (TTR) and retinol-binding protein (RBP) which were all correlated with one another. Total and free thyroxin and total and free triiodothyronine were positively correlated as were the concentrations of the total and free hormones. Thyrotropin (TSH) was negatively correlated with total and free thyroxin and positively correlated with free triiodothyronine. Thyroxin and triiodothyronine in both free and combined forms were all correlated with thyroxin-binding globulin which in turn was negatively correlated with the triad retinol, RBP and TTR. The triad was also negatively correlated with C-reactive protein. Urinary I excretion was positively associated with total thyroxin and negatively associated with TSH. The anaemia found was not nutritional in origin but due to the effect of infestation with intestinal parasites and malaria.
