“…A taxa de adesão, avaliada em 24,2% dos artigos estudados, variou de 67 a 85%, sendo que o valor mais alto correspondeu ao estudo no qual se verificou viés de seleção, com indicação do diretor da creche para os respondentes mais cooperativos. Todos os estudos que forneceram a taxa de adesão utilizaram o registro alimentar 9,10,17,19,20,30,39,40 . Uma questão que preocupa o pesquisador é o quanto seus resultados podem ser afetados pela adesão, na medida em que os indivíduos que não respondem poderiam ser, no caso de pré-escolares, por exemplo, os pais das crianças mais afetadas por distúrbios nutricionais ou que tivessem uma alimentação mais desequilibrada.…”

Os estudos dietéticos fornecem elementos elucidativos que contribuem para a compreensão da dinâmica e determinação dos diversos agravos nutricionais que atingem a população infantil. As investigações do consumo alimentar de crianças pequenas utilizam os mesmos métodos de inquéritos empregados nas demais faixas etárias, diferenciando-se pela necessidade de um respondente, geralmente um dos pais ou o cuidador da criança. O objetivo do trabalho foi identificar os principais métodos de avaliação do consumo alimentar utilizados nos inquéritos com pré-escolares, assim como os itens e formas de análise mais comumente empregados. Verificou-se que os estudos apresentaram baixa comparabilidade, em função, entre outros fatores, do uso de diferentes formas de análise e metas de ingestão. O recordatório de 24h foi o método mais utilizado, geralmente associado a um outro método de inquérito. Ainda são poucos os estudos que empregam as novas cotas dietéticas de referência para avaliação da adequação das dietas. No Brasil, assim como nos demais países em desenvolvimento, os estudos ainda priorizam as carências nutricionais. Apesar do aumento no número de estudos brasileiros nos últimos anos, as pesquisas existentes são de limitada comparabilidade, sendo essencial que se invista em uma estrutura (tabelas, softwares, seleção de indicadores) que possibilite um diagnóstico nutricional mais fidedigno e com potencial de comparação.

“…Iron has vital functions in the body, some of which are transferring oxygen from the lungs to the organs of the body, electron transport in internal reactions of the cell in the body, and participating in the building of various enzymes in body tissues (1,2). Unfavorable reception of iron is the most important cause of iron deficiency anemia (IDA) that can be prevented by modifying nutritional and dietary diet (3,4). Iron deficiency is the most common nutritional problem in the world that about 4 to 5 billion people in the world suffer from and two billion people (more than 30 percent) of the world population has iron deficiency anemia (5).…”

Iron is one of the most important elements forming the body and an essential metal for many biological processes in mammals. According to studies, anemia can cause numerous side effects in the body. Because of the effectiveness of iron in myelinated nerves, this illness can cause hearing loss and vision problems as well, and in students, it can even cause academic failure and learning problems and intensify behavioral disorders. Therefore, to collect the statistics of the prevalence of the disorder to inform parents, the present study was conducted to assess the prevalence of iron deficiency anemia in high school students in Iran using meta-analysis method. This study was continued in review form using the keywords anemia, iron deficiency anemia, and anemia prevalence with a consideration of the articles in Pubmed, Iranmedex databases and Scientific Information Database of SID in related topics with 89 articles. Time domain for searching articles and related books and was mainly from 1991 onwards. Studies on the prevalence of iron deficiency anemia in high school students show different results. Recent statistics based on published articles at home and abroad demonstrate the prevalence of iron deficiency anemia equal to 10.6%, (with a 95% confidence interval: 9.7 to 11.5) until 2014. The disease can cause hearing and vision disorders in adolescents. Moreover, it can cause academic failure and learning problems and intensify behavioral disorders in students. Given that children's health is an indicator of health planning of family for them, attention to the factors preventing iron deficiency anemia and its treatment is essential for students. Following this study, it is suggested that by correcting diet as the first step of prevention of catching this diseases, we take a step towards preventing it.

“…Little information is known regarding the nutritional status of school-aged children, especially among ethnic minority and 'hard-to-reach' populations such as the Qashqa'i tribespeople (Zohouri & Rugg-Gunn, 2002). The Qashqa'i are a Turkishspeaking minority ethnic group of more than a half a million people residing in southern Iran.…”

Nutritional status of schoolchildren in rural Iran

et al. 2005

The present study compared the nutritional status of schoolchildren from recently settled, ethnic minority tribespeople with those from a Persian village in southern Iran. Height and weight were measured and blood was collected from school children at three time points over 1·5 years. Supplemental Fe was provided to children with low Hb after the first screening. Twenty-one per cent of the children were wasted, 57 % were stunted and 23 % were anaemic. No statistically significant difference in the prevalence of wasting, stunting and anaemia was found between gender or ethnic groups. Children over the age of 12 years had a higher prevalence of wasting than children aged below 12 years. In a sub-sample of forty-one children the average BMI-for-age decreased. Fe supplementation increased Hb levels to normal in most children, but did not increase Fe level in a few children. Dietary deficiency of micronutrients, especially Zn and Fe, probably accounts for the high prevalence of stunting and anaemia in these children. Infection with Helicobacter pylori is another possible explanation for the Fe-deficiency anaemia. Further investigation is in progress to determine the cause(s) of the observed deficiencies. Iran: Qashqa'i: Schoolchildren's health statusIran is located in the Middle East, bordering the Gulf of Oman, the Persian Gulf and the Caspian Sea, between Iraq and Pakistan. It shares borders with Afghanistan, Armenia, Azerbaijan, Iraq, Pakistan, Turkey and Turkmenistan. Iran is divided into twentyeight provinces (Fig. 1). The population is young, with a median age of 22·9 years, and about 29 % are under the age of 15 years (CIA, 2003).Iran faces several public health challenges. The infant mortality rate is 44·17 per 1000 live births (CIA, 2003). Malnutrition is not uncommon especially in rural and southern Iran. According to a 1998 nationwide study of children ,5 years of age, approximately 15 % are moderately or severely stunted (,22 SD weight-for-age) and about 5 % moderately or severely wasted (,22 SD weight-for-height; Ministry of Health and Medical Education, 1998). Substantial differences exist between rural and urban provinces. Twenty-two per cent of rural children aged ,5 years are stunted compared with 11·0 % of urban children. The highest rate of stunting is 38·1 % in Sistan va Baluchestan in the south east and the lowest is 6·8 % in Gilan in the north east. The difference in the prevalence of wasting between rural and urban areas is small, with 5·6 % of urban and 4·6 % of rural children meeting the criteria for wasting. However, the difference between provinces is large. The highest rate of wasting is 11·3 % in Harmozgan in the south west and the lowest rate is 1·1 % in Golestan in the north west (Ministry of Health and Medical Education, 1998).The same study revealed that only 14 % of children had their weight recorded regularly on their growth card, with 69 % having two or fewer weights recorded (Ministry of Health and Medical Education, 1998). During the week preceding the interview, protein-rich fo...
