Abstract
ObjectivesMoringa oleifera has been used for centuries due to its medicinal properties and health benefits. The plant has antifungal, anti-viral, and anti-inflammatory properties. We aimed to evaluate the effect of consumption of Moringa leaves, along with a regular diet on serum hemoglobin and retinol and underweight status among rural Bangladeshi adolescent girls.MethodsThis school-based quasi-experimental study involved 226 adolescent girls (12–14 years-old). Intervention group (n = 113) received a meal comprising rice, concentrated dal, and fried potato with Moringa pakora (oil-fried snack); the control group (at a different school in an adjacent area with similar population demographics) received calorie-matched meal without Moringa pakora for 6 months. We used generalized liner regression (GLM) analysis, to explore the effect of the intervention among the groups between baseline and endline.ResultsMean age of the intervention and control groups were 12.7 ± 0.7 and 13.3 ± 0.8 years, respectively. After adjusting for maternal education, absenteeism, asset index, BMI-for-age Z-score, GLM regression showed significant positive changes in hemoglobin (intervention vs. control: coef = 0.41, P = 0.010) and serum retinol (coef = 0.27, P = 0.00). No significant changes in weight was observed between groups.ConclusionConsumption of Moringa leaves has the potential to improving hemoglobin and serum retinol level and should be encouraged as regular diet.

Abstract
The aim of this study was to explore the relationship of iron and zinc deficiencies and anemia in children aged under 5 years living in malaria endemic area of South Kivu/DRC. We conducted a cross-sectional study in the health zone of Miti Murhesa in South Kivu/DRC. A total of 1088 children in good general health were included in this study. Almost 40% of children were anemic. The prevalence of iron deficiency (ID) was found in 34.9% and 49.1% children based on ferritin or free erythrocyte protoporphyrin (FEP), respectively. If anemia is present, we found iron deficiency anemia (IDA) according to the WHO-criteria (ferritin) in 31%, and according to FEP in 66% of children. The overall prevalence of zinc deficiency was 17.6%. If anemia is present, zinc deficiency was found in 24.4% of children. Inflammation/infection, based upon CRP, was present in 39.7% children. The independent factors associated with anemia were recent illness, middle upper arm circumference, weight-for-height, ID according to FEP, zinc deficiency, and submicroscopic Plasmodium infection. A high prevalence of ID was observed in children in South Kivu according to FEP. Ferritin as acute phase protein was less suited in this population due to a high frequency of infection/inflammation. Iron and zinc deficiencies were found to be significantly associated with anemia in this population.

Abstract
Anemia is a global public health problem. The prevalence of anemia among different ages, genders or ethnic groups must be clarified in order to solve problems. This study proposed to determine the prevalence and factors related to anemia among the Muslim school-age population in Nakhon Si Thammarat, Thailand. Socio-demographic and anthropometric data were collected by a structured questionnaire. Blood samples were collected from 200 school-age subjects. The thalassemia screening was performed with KKU-OF and KKU-DCIP reagents. The prevalence of anemia in this study was 36.5%, divided into males and females, 33.3% and 39.1%, respectively. The means of Hb, Hct, MCV, MCH, and MCHC in the anemic group were significantly lower. The positive results for KKU-OF or KKU-DCIP or both were 15.0%, 2.5%, and 1.0%, respectively. The result of positive OF test was a significantly independent factor for anemia. The number of family members was 5 to 7 and more than 7 persons are related factors for anemia in this study. In summary, the contribution of thalassemia and socio-economic factor are associated factors to anemia in this population. These findings should be addressed in public health strategies for the control of anemia of school-aged Muslims in the region.

Abstract
OBJECTIVE The association of Fe metabolism with obesity in children remains unclear. The present study aimed to assess the status of Fe metabolism parameters, the prevalence of anaemia, Fe deficiency (ID) and Fe-deficiency anaemia (IDA), and the associations of these variables with obesity in Chinese schoolchildren. DESIGN A cross-sectional study conducted in 5295 schoolchildren aged 7-11 years in Guangzhou, China, 2014-2015. Full data of anthropometric and Fe metabolic parameters were collected to assess obesity, anaemia, ID and IDA. Logistic regression models were established to determine the possible associations of anaemia, ID and IDA with obesity. Two-tailed P values of <0·05 was considered statistically significant. SETTING Guangzhou City, China. PARTICIPANTS Schoolchildren aged 7-11 years (n 5295). RESULTS In this sample, mean Hb concentration was 128·1 g/l and the prevalence of anaemia, ID and IDA was 6·6, 6·2 and 0·6 %, respectively. Of the participants, 14·0 % were overweight and 8·8 % were obese. Importantly, obesity was associated with lower anaemia risk (adjusted OR = 0·553; 95 % CI 0·316, 0·968) but higher ID risk (adjusted OR = 1·808; 95 % CI 1·146, 2·853) after adjustment for confounders. No significant relationship was found between obesity and IDA. CONCLUSIONS Our results confirmed that anaemia and ID remain public health concerns among schoolchildren in Guangzhou, while IDA is remarkably less prevalent. Furthermore, obesity was associated with lower anaemia risk, but higher ID risk. More efforts should be made to prevent the onset of ID and obesity in the same individual, thus improving the health and fitness of children.

Abstract
AbstractObjectiveThe present study aimed to determine the prevalence of anaemia, iron deficiency (ID) and iron-deficiency anaemia (IDA) among female adolescents in the Gaza Strip, Palestine, as well as the risk factors involved in these conditions.DesignThe study was conducted using the quantitative descriptive method with a cross-sectional design. Data were collected using an FFQ and sociodemographic, sedentary behaviour and physical activity questionnaires. Anthropometric measurements and blood analyses were also conducted.SettingThe study population included all Palestinian female adolescents enrolled in secondary schools in the academic years 2015–2016. Five female secondary schools were selected randomly from five governorates of the Gaza Strip.SubjectsFemale adolescents (n330) aged 15–19 years in the selected secondary schools were enrolled randomly.ResultsPrevalence of anaemia, ID and IDA among female adolescents in the Gaza Strip, Palestine, was 35·8, 40·3 and 26·0 %, respectively. A significant association (P<0·05) existed between ID, anaemia and IDA and dietary habits, including skipping breakfast and amount of junk food intake. Also, low consumption of fruits and vegetables was associated with IDA in the female adolescents. A statistically significant association was found between mother’s education and ID but not with the other sociodemographic factors.ConclusionsThe study shows that there is an alarming problem of anaemia and IDA in the Gaza Strip, Palestine. This may indicate that there are insufficient nutrition education programmes, particularly inside schools or by the mass media.

Abstract
Certain population sub-groups in the United States are vulnerable to micronutrient malnutrition. Nationally representative data from the National Health and Nutrition Examination Survey (NHANES) describing the biochemical status of vitamins A, B6, B12, C, D, E, folate, and anemia, were aggregated to determine the overall risk of multiple concurrent deficiencies in U.S. children and adults (n = 15,030) aged >9 years. The prevalence of deficiency risk according to socio-demographic, life-stage, dietary supplement use, and dietary adequacy categories was investigated. Thirty-one percent of the U.S. population was at risk of at least one vitamin deficiency or anemia, with 23%, 6.3%, and 1.7% of the U.S. population at risk of deficiency in 1, 2, or 3-5 vitamins or anemia, respectively. A significantly higher deficiency risk was seen in women (37%), non-Hispanic blacks (55%), individuals from low income households (40%), or without a high school diploma (42%), and underweight (42%) or obese individuals (39%). A deficiency risk was most common in women 19-50 years (41%), and pregnant or breastfeeding women (47%). Dietary supplement non-users had the highest risk of any deficiency (40%), compared to users of full-spectrum multivitamin-multimineral supplements (14%) and other dietary supplement users (28%). Individuals consuming an adequate diet based on the Estimated Average Requirement had a lower risk of any deficiency (16%) than those with an inadequate diet (57%). Nearly one-third of the U.S. population is at risk of deficiency in at least one vitamin, or has anemia.

Abstract
BACKGROUND AND OBJECTIVE In resource-poor settings, micronutrient deficiencies such as vitamin A deficiency may co-exist with iron-deficiency. In this study we assessed the iron and vitamin A status of schoolchildren and the association between vitamin A and iron status. METHODS A cross-sectional design using the baseline data of a dietary intervention trial conducted among randomly selected 5-12 years old schoolchildren (n = 224) from 2 rural schools in northern Ghana. Hemoglobin (Hb), serum ferritin (SF) and serum transferrin receptor (sTfR) concentrations were used as measures of iron status. Retinol binding protein (RBP) was used as a measure of vitamin A status. Subclinical inflammation (SCI) was measured using C-reactive protein (CRP) and α1-acid glycoprotein (AGP) concentrations. We examined the cross-sectional association between vitamin A and iron status biomarkers with multiple linear regressions. RESULTS The proportions of schoolchildren with anemia (WHO criteria), iron-deficiency (ID, SF <15μg/l and/or sTfR >8.5mg/l) and iron-deficiency anemia (IDA, concurrent anemia and ID) were 63.8%, 68.3% and 46.4% respectively. Low or marginal vitamin A status (0.70 μmol/l ≤ RBP < 1.05μmol/l) was present in 48.2% while 37.5% of the schoolchildren had vitamin A deficiency (VAD, RBP <0.70 μmol/l). The prevalence of SCI as well as concurrent VAD and ID were 48.7% and 25% respectively. RBP was associated with Hb (β = 7.2, P = 0.05) but not SF (β = 20.7, P = 0.33) and sTfR concentration (β = 12.0, P = 0.63). In the presence of SCI, RBP was not associated with hemoglobin status but a significant positive association was observed among children without SCI. CONCLUSIONS The study shows that RBP is significantly associated with Hb concentration but not with SF and sTfR. The observed relationship between RBP and Hb is only significant in the absence of SCI.

Abstract
Previous studies have demonstrated the importance of eating behaviour regarding dietary variety and nutrient intake of children. However, the association between picky eating and growth of children is still a topic of debate. This study sought to estimate the prevalence of picky eating and to identify possible associations with the growth of school-age children in China. In this survey, 793 healthy children aged 7-12 years were recruited from nine cities and rural areas in China using a multi-stage cluster sampling method. Data collected included socio-demographic information and parents' perceptions of picky eating using a structured questionnaire, nutrient intake using 24-hour dietary recall, weight and height using body measurements, and intelligence using the Wechsler Intelligence Scale for Children. Blood samples were collected and analysed for minerals. The prevalence of picky eating reported by parents was 59.3% in children. Compared with non-picky eaters, picky eaters had a lower dietary intake of energy, protein, carbohydrates, most vitamins and minerals, and lower levels of magnesium, iron, and copper in the blood (p < 0.05), and also had a 0.184 z-score lower in height for age (95% CI: -0.332, 0.036; p = 0.015), a 0.385 z-score lower in weight for age (95% CI: -0.533, -0.237; p < 0.001), a 0.383 z-score lower in BMI for age (95% CI: -0.563, -0.203; p < 0.001), and scored 2.726 points higher on the intelligence test (95% CI: 0.809, 4.643; p = 0.006) when adjusted for children's birth weight and food allergy, mothers' education, and family income. Picky eating behaviour towards meat, eggs and vegetables showed negative associations with growth. Picky eating behaviour is prevalent in school-age children in China and may have a negative effect on growth.

Abstract
Iron is one instrumental micronutrient to any healthy pregnancy. Its deficiency (with or without overt anaemia) remains a significant risk factor to gestational complications. In the present study, 307 pregnant women were prospectively recruited from Northern zone of Ebonyi State to assess their gestational iron status. The iron status of the subjects was determined with serum iron level and heamoglobin concentration, using atomic absorption (flame) spectrometric and Drabkin's methods respectively. Statistical analysis was performed using the computer software: "Statistical Program for Social Sciences" (SPSS for windows version 15.0). The result showed that 177 (59.8%) of the pregnant women were iron deficient, while 45.6% of them was at the risk of iron deficiency anaemia. Parity, educational level, occupation and living accommodation showed significant (p < 0.05) influence on the iron status of the subjects. It could be concluded that gestational iron deficiency with its related anaemia was yet to be effectively brought under control in our society; with parity and economic status implicated as risk factors.

Abstract
Background In 2004, wheat flour fortification (WFF) with iron was implemented in Kazakhstan as a public health strategy to increase the iron intake of all women of childbearing age and of children. In 2003, before starting the flour fortification program, a communication campaign on health education took place in a region with a high prevalence of iron deficiency anemia (IDA). The present study aimed to evaluate the prevalence of anemia, iron deficiency and IDA before and after the campaign. In addition, knowledge about IDA and its prevention, as well as awareness about fortified wheat flour, was assessed. Methods The subjects of the study were women aged 15-49 years and children aged 2-14 years. The study was carried out in urban and rural areas of Kyzyl-Orda region in 2003 before (March) and after (December) the campaign. Blood samples were collected in order to measure hemoglobin and serum ferritin. In March 80 women and 57 children in the urban area, and 41 women and 41 children in the rural area, participated in the IDA testing. The corresponding participants in December numbered 62, 52, 52, and 57, respectively. The impacts of the communications and information received by participants during the campaign was surveyed with a questionnaire for 195 women in March and 198 women in December including some who participated in the IDA testing. Results In March, the prevalence of anemia was 52.0% among 121 women and 58.1% among 98 children, and those with low iron reserve were 63.6%, 49.1% and IDA 40.5%, 11.0%, respectively. In December, the prevalence of anemia had significantly decreased among rural women (from 65.9% to 48.0%, p < 0.05) and among urban children (from 63.1% to 11.5%, p < 0.001). The prevalence of iron deficiency was significantly reduced among the children (from 51.1% to 24.8%, p < 0.001). IDA prevalence was meaningfully decreased among women in urban and combined areas (from 37.5% to 15.0% and 40.5 to 14.8%, respectively, p < 0.001) and among urban children (from 7.1% to 2.1%, p < 0.05). The surveys found that most women knew about IDA and its prevention and that the numbers were similar both in March and in December. The knowledge of the anti-anemic effect of wheat fortified flour improved significantly over the period of the campaign among women both in urban (from 48.5% to 80.9%, p < 0.001) and rural (from 69.8% to 88.6%, p < 0.001) areas. Conclusion The study demonstrated that the communication campaign before implementation of WFF program was effectively carried out, giving a biological impact on hematological indices.

Abstract
BACKGROUND Anemia is a widespread public health problem, which is due to many factors, nutritional or non-nutritional. Iron, vitamin A and growth status were assessed to investigate anemia of preschool children in suburb Chongqing, China. METHODS A descriptive, cross-sectional survey was performed on 459 preschool children aged 2 to 7 years randomly chosen from the kindergartens in 6 suburban districts of Chongqing. Weight and height levels, hemoglobin, erythrocyte protoporphyrin, serum retinol, and ferritin concentrations were measured to evaluate the anthropometric and nutritional status. RESULTS The rates of stunt, underweight, overweight, wasting, obesity, anemia, iron deficiency, vitamin A deficiency (VAD), and marginal VAD were 6.3%, 3.9%, 3.7%, 1.5%, 3.1%, 23.5%, 15.0%, 6.3% and 25.9%, respectively. Serum retinol concentration was significantly lower in children with anemia than in those without anemia (P=0.003), and the retinol concentration was associated with hemoglobin (Pearson's correlation coefficient, r=0.22, P<0.01). Children with VAD had a significantly increased risk for anemia (odds ratio, 2.56; 95% confident interval, 1.15-5.70). In all 108 children with anemia, only 42 were related to VAD and 12 related to iron deficiency, suggesting that almost half of the anemia children cannot be explained solely by iron deficiency or VAD. CONCLUSIONS Vitamin A and iron deficiency are still public health problems in some localities of China. Public health interventions in anemia control should be used to eliminate deficiencies of vitamin A, iron, and other micronutrients by deliberate supplementation. Attention must be paid to such deficiencies in high-risk groups, especially in preschool children.

Abstract
Iron deficiency anemia is a major health problem in developing countries. Anemia reduces physical work capacity and cognitive function and adversely affects learning and scholastic performance in schoolgirls entering adolescence. A cross-sectional study was conducted to determine the prevalence of iron deficiency, iron deficiency anemia and anemia among adolescent school girls aged 14-20 years from 20 different high schools located in three educational areas of Kermanshah, the capital of Kermanshah province in Western Iran. The prevalence of anemia (Hb<12 mg/dl) among adolescent school girls was 21.4%. Iron deficiency using a ferritin level <12 microg/l was found in 23.7% of studied girls. There were 47 girls (12.2%) with iron deficiency anemia (Hb<12 g/dl and ferritin <20 microg/l). Around 57.3% of anemic girls were iron deficient. There were no significant differences between the presence of anemia and the level of education of parents. The mean levels of hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean cell hemoglobin (MCH) and mean cell hemoglobin concentration (MCHC) in studied adolescent girls from Western Iran were found to be lower than those reported for females aged 12-18 years. In conclusion, regarding the detrimental long-term effects and high prevalence of iron deficiency, iron deficiency anemia and anemia in Kermanshah, Western Iran its prevention could be a high priority in the programs of health system of the country and supplementation of a weekly iron dose is recommended.

Abstract
AbstractIron deficiency (ID) is the most prevalent micronutrient deficiency in the world, particularly in developing countries. Blood samples and a qualitative FFQ on Fe- and vitamin C-rich foods were obtained in 180 adolescent girls aged 12 to 17 years living in two boarding schools from south Benin. ID, defined as serum ferritin either <20μg/l or 20–50μg/l, plus two of the following parameters: serum Fe<11μmol/l, total iron-binding capacity>73μmol/l or transferrin saturation<20%, was found in 32% of subjects. Anaemia (Hb<120g/l) was found in 51% of adolescents, while 24% suffered from iron-deficiency anaemia (IDA) (ID and Hb<20g/l). After adjusting for confounding factors (age, mother's and father's occupation, household size) in a logistic regression equation, subjects having a low meat consumption (beef, mutton, pork) (<4 times/week) were more than twice as likely to suffer from ID (OR=2·43; 95% CI 1·72, 3·35;P=0·04). Adolescents consuming less fruits (<4 times/week) also had a higher likelihood of suffering from ID (OR=1·53; 95% CI 1·31, 2·80;P=0·03). Finally, subjects whose meat consumption was low were twice as likely to suffer from IDA (OR=2·24; 95% CI 1·01, 4·96;P=0·04). The prevalence of ID represents an important health problem in these Beninese adolescent girls. A higher consumption of Fe-rich foods and of promoters of Fe absorption (meat factor and vitamin C) is recommended to prevent ID deficiency in these subjects.

Abstract
Intestinal parasitic infections (IPI), especially helminths, represent a major public health problem that increase iron deficiency anaemia in developing countries. This study investigated the prevalence, risk factors and nutritional consequences of IPIs in 180 adolescent girls aged 12-17 years living in two boarding schools in southern Benin. Data were collected using a structured questionnaire and laboratory analysis of blood and faecal samples. The relationships between socioeconomic indicators, IPIs and iron status were analysed using logistic regression analysis. Fifty percent of the subjects were infected with at least one IPI: 2% with helminths, 41% with protozoa and 7% with two or more intestinal parasites. Adolescent girls from a large family and those whose mothers were manual workers showed a higher risk of intestinal parasitism (odds ratio (OR)=3.5, 95% CI 2.5-5.2 (P=0.02) and OR=2.4, 95% CI 2.0-3.0 (P=0.03), respectively). Likewise, drinking untreated water was also a high risk factor for infection (OR=2.3, 95% CI 1.5-2.4; P=0.03). No significant association was observed between IPIs and iron deficiency or iron deficiency anaemia, which can be explained by the low wormload observed. These findings reinforce the need to involve mothers in health initiatives to control intestinal parasitism in Benin.

Abstract
BACKGROUND/OBJECTIVES Vitamin A deficiency (VAD) is a world public health problem contributing to the increase in childhood morbidity and mortality in developing countries and severe deficiency of vitamin A may lead to xerophthalmia and blindness. The objective of this study was to determine the prevalence of VAD among Brazilian school-aged children attended at a primary health unit and to verify if some considered risk factor was associated with VAD in this group. SUBJECTS/METHODS A descriptive prospective transverse study was conducted on 103 randomly selected children. A total of 54 boys and 49 girls aged 5.5-11 years had the relative dose-response (RDR) test performed on. Possible ocular alterations related to vitamin A and the status of anemia, serum zinc, some acute-phase proteins, and anthropometric situation were determinate by an analytic design. RESULTS No child presented xerophthalmia. Serum retinol values lower than 1.05 and 0.7 micromol l(-1), respectively were found in 26.2 and 5.8% of the children. The prevalence of hypovitaminosis detected by RDR test was 20.4%. The following variables and their relationship with VAD were evaluated: sex (P=0.33; 95% confidence interval 0.61-4.34), weight and height (P> or =0.5), hemoglobin (P=0.15), C-reactive protein (P=0.56; 95% confidence interval 0.75-18.26), alpha-1-acid-glycoprotein (P=0.56; 95% confidence interval 0.15-15.42) and serum zinc (P=0.31). None of these variables was related to VAD. CONCLUSIONS In this population, the prevalence of VAD detected could be considered a public health problem. School-aged children can be considered at risk for VAD mainly of a subclinical level, even without some associated risk factors.
