Prevalência da anemia e fatores associados em crianças de seis a 59 meses de Pernambuco

Modelling the interrelationships between potential risk factors and childhood Co-morbidity of Malaria, Anaemia, and stunting in children less than five years in Burundi

Background

Anaemia, malaria, and stunting remain health problems, especially in children younger than five years, and those conditions are linked to morbidity and mortality. The main objective was to assess the relationships between anaemia, malaria, and stunting. Also, the current study aimed to understand the complex interrelationships between explanatory factors, and their direct or indirect relationship with childhood malaria, anaemia, and stunting in Burundi.

Methods

The study used secondary data from the Demographic and Health Survey in Burundi (BDHS) conducted on the March 7, 2017, with a weighted sample size of 13611 children younger than five years. A multivariate structural equation model (SEM) was used to evaluate the interrelationships between dependent variables and their direct or indirect relationship with childhood malaria, anaemia, and stunting. SEMs diverge from other techniques, as they look at the effects on hypothesised relationships from both direct and indirect perspectives (Takele et al., 2023) [1]. The variables with statistical significance were set at a p-value <0.05.

Results

The findings from this study indicated an association between anaemia, malaria, and stunting (p < 0.001). The environmental and household factors were statistically significant (p < 0.038 and p < 0.001 respectively) and positively impacted childhood malaria, anaemia, and stunting. The results also indicated that the household factors were statistically significant (p < 0.001) predictors of childhood malaria, anaemia, and stunting. Furthermore, the findings from this study revealed that geophysical factors have a positive significant (p < 0.001) impact on childhood malaria, anaemia, and stunting via the mediating of the household factors. Contrastingly, with the environmental factors as a mediator, we observe a negative significant (p < 0.001) impact on childhood malaria, anaemia, and stunting. Lastly, the results showed that demographic factors had a negative significant (p = 0.004) effect on childhood anaemia, malaria, and stunting via the mediating of household factors.

Conclusion

The findings from this study revealed an association between malaria, anaemia, and stunting, which imply that these conditions could contribute to collaborative improvements in child well-being. In addition, child demographic, household, environmental, and geographic factors were direct and indirect important drivers of childhood malaria, anaemia, and stunting. Therefore, improving sanitation, access to clean water, nutrition practices, and health care, especially for children from rural areas, and uneducated mothers with poor backgrounds could help to control and eliminate stunting, anemia, and malaria in children younger than five years in Burundi.

Determinants of normal haemoglobin concentration among under-five children in Sub-Saharan Africa: a Positive deviance inquiry using cross-sectional study design

BACKGROUND

Low haemoglobin level in children is linked with short-term and long-term consequences including developmental delay. Globally, over half of the children under the age of five years had low haemoglobin concentration. However, there is limited research on the prevalence and determinants of normal haemoglobin concentration among under-five children in sub-Saharan Africa.

OBJECTIVE

To assess determinants of normal haemoglobin concentration among under-five children in SSA.

DESIGN

Cross-sectional study design using a positive deviance approach SETTING: 33 SSA countries.

PARTICIPANTS

129 408 children aged 6-59 months PRIMARY AND SECONDARY OUTCOME MEASURES: A multilevel Poisson regression model with robust variance was fitted to identify determinants of normal haemoglobin concentration. An adjusted prevalence ratio with a 95% CI was reported to declare the statistical significance.

RESULT

The pooled prevalence of normal haemoglobin concentration among under-five children in SSA was 34.9% (95% CI: 34.6% to 35.1%). High maternal education, middle and rich household wealth, female child, frequent antenatal care visits, non-anaemic mothers, taking anthelmintic drugs and normal nutritional status were associated with increased odds of normal haemoglobin concentration. On the other hand, higher birth order, having fever and diarrhoea, rural residence were associated with lower odds of normal haemoglobin levels.

CONCLUSION

According to our finding, only four out of 10 under-five children in SSA had a normal haemoglobin level. This finding proved that anaemia among children in SSA remains a serious public health concern. Therefore, improving maternal education, provision of drugs for an intestinal parasite and early detection and treatment of maternal anaemia, febrile illness and diarrhoeal disease is important.

Magnitude, Associated Factors and Morphological Types of Anemia Among Hospitalized 6-59 Months Age Children at Jimma Medical Center, Southwest Ethiopia - A Hospital-Based Cross-Sectional Study

Background

Anemia is among the major public health problems that cause significant morbidity and mortality among children around the world. Anemia in children of age 6 months to 5 years is a major health problem in most developing world countries with estimated prevalence of about 43%.

Objective

To determine the magnitude, associated factors and morphological types of anemia among hospitalized 6-59 months age children from June 15 to October 15, 2022 at Jimma Medical Center, southwest Ethiopia.

Methodology

Hospital-based cross- sectional study design was conducted from June 15 to October 15, 2022 at Jimma Medical Center, involving 383 hospitalized children aged 6-59 months by employing convenient sampling technique. Data of sociodemographic characteristics and other associated factors of the study individuals waere collected using a pre-structured questionnaire. Clinical data were collected by physical examination and from history of client by medical interns and nurses. Then 3 mL venous blood was collected and analyzed for complete blood count. Data were coded, cleared and entered into EpiData version 4.6 and exported to SPSS version 25 for analysis. Bivariable and multivariable binary logistic regression was used to identify associated factors.

Results

The overall prevalence of anemia among hospitalized 6-59 months age children was 57.2%; out of them 30.82% were moderate. In the present study children with malaria infection, AOR = 1.15 (95% CI: 0.017, 0.781), Cchildren with severe malnutrition, AOR = 2.046 (95% CI: 0.306, 1.366), and children with low family income, AOR = 2.6 (95% CI 0.475, 0.894) were independent variables associated with anemia.

Conclusion and Recommendation

Anemia among study participants is found to be a severe public health problem. Based on this finding, more intervention is needed with health education on nutrition and child feeding.

Prevalence and Associated Risk Factors of Anemia Among Hospitalized Children in a Tertiary Level Hospital in Botswana

Anemia is a global health concern and has been associated with long term cognitive and behavioral adverse effects. A cross sectional study was conducted to determine the prevalence of and risk factors for anemia in infants and children between 6 months to 5 years of age admitted to a tertiary hospital in Botswana. Baseline full blood count of every patient admitted during the study period was assessed to determine if anemia was present. Data were collected from patient's medical inpatient chart, electronic medical record (Integrated Patient Management System (IPMS)), and through interviewing parents and caregivers. Multivariate logistic regression model was used to identify risk factors of anemia. A total of 250 patients were included in the study. Prevalence of anemia in this cohort was 42.8%. There were 145 (58%) males. Of the patients with anemia, 56.1%, 39.2%, and 4.7% had mild, moderate, and severe anemia, respectively. Microcytic anemia consistent with iron deficiency was identified in 61 (57%) patients. Age was the only independent predictor of anemia. Children aged 24 months and more had a 50% lower risk of having anemia than their younger counterparts (odds ratio (OR) 0.52; 95% Confidence Interval (95% CI) 0.30 to 0.89). The findings of this study demonstrate anemia as a serious health concern in the pediatric population in Botswana.

Temporal evolution of anemia in children aged six to 59 months in the state of Pernambuco, Brazil, 1997 to 2016

OBJECTIVE

To analyze the temporal evolution of anemia in children aged six to 59 months in Pernambuco, based on population surveys from 1997, 2006, and 2016 and the factors associated with the situation in 2016.

METHODS

The field studies took place in the participants' households, in the Recife Metropolitan Area, as well as in the urban and rural inland. The trend study of anemia in children used data from the State Health and Nutrition Survey (Pesquisa Estadual de Saúde e Nutrição - PESN) II (40.9%) and III (32.8%). Data from PESN IV were collected using questionnaires administered to families to verify socioeconomic and individual conditions, as well as anthropometric - weight and height - and biochemical - hemoglobin - records. We adopted the test for trend in proportion for the time trend study and Poisson regression for hypothesis tests for the associated factors. Statistically significance was set at a p-value<0.05.

RESULTS

In 2016, the prevalence of anemia was 24.2%, indicating a significant reduction in disease incidence. In children aged 6-23 months, this number decreased from PENS II and III to PENS IV - 63 and 55.6 to 37.7% (p<0.001), respectively. In 2016, the statistically significant variables for anemia in children were maternal hemoglobin, child's age, current or recent case of diarrhea, and weight-for-age index.

CONCLUSION

Between 1997 and 2016, anemia rates decreased, showing an epidemiological trend that can contribute to continuously improve the health of children under five years of age in Pernambuco.

Individual-and community-level factors associated with anemia among children aged 6–23 months in sub-Saharan Africa: evidence from 32 sub-Saharan African countries

Background

Anemia among children aged 6–23 months is a major public health problem worldwide specifically in sub-Saharan Africa (SSA). Anemia during the childhood period causes significant short-and long-term health consequences. However, there is a paucity of evidence on Anemia among children aged 6–23 months in SSA. Therefore, this study examined the individual- and community-level factors associated with anemia among children aged 6–23 months in sub-Saharan Africa.

Methods

A secondary data analysis was done based on the most recent Demographic and Health Survey (DHS) of 32 sub-Saharan African countries. A total weighted sample of 51,044 children aged 6–23 months was included for analysis. We have used a multilevel proportional odds model to identify predictors of severity levels of anemia. Variables with p < 0.2 in the bivariable analysis were considered for the multivariable analysis. In the multivariable multilevel proportional odds model, the Adjusted Odds Ratio (AOR) with the 95% Confidence Interval (CI) was reported to declare the statistical significance and strength of the association.

Results

In this study, about 76.6% (95% CI: 76.2%, 76.9%) of children aged 6–23 months in sub-Saharan Africa were anemic. In the multivariable multilevel proportional odds model, being female, being aged 18–23 months, higher level of maternal education, being larger size at birth, belonging to a wealthier household, getting four ANC visits and above, advanced maternal age, and belonging to a community with high maternal education were significantly associated with lower odds of higher levels of anemia. On the other hand, being twin birth, being smaller size at birth, being of a higher order of birth, having fever in the last two weeks, and distance to a health facility were significantly associated with higher odds of higher levels of anemia.

Conclusion

The study found that more than three-fourths of children aged 6–23 months in sub-Saharan Africa were anemic. This finding proved that the severity levels of anemia among children in sub-Saharan Africa remain a serious public health concern. Therefore, to curve this problem enhancing maternal education, promoting maternal health service utilization, and improving health care access is crucial. In addition, health care providers better give special emphasis to twin births, higher-order birth, and those belonging to poor households to reduce the incidence of anemia among children aged 6–23 months in SSA.

Joint modelling of anaemia and stunting in children less than five years of age in Lesotho: a cross-sectional case study

BACKGROUND

 Anaemia and stunting remain jointly a serious health issue worldwide especially in developing countries. In Lesotho, their prevalence is high, particularly among children less than 5 years of age.

OBJECTIVES

 The primary objective was to determine the association between anaemia and stunting, and identify factors relating to both conditions among children younger than 5 years in Lesotho.

METHODS

 This cross-sectional study used secondary data from 3112 children collected during the 2014 Lesotho Demographic Health Survey (LDHS). Haemoglobin (Hb) levels were adjusted for altitude and a level less than 11 g per deciliters (11 g/dl) was determined as the cutoff for being anaemic. A child with the height-for-age z score (HAZ) below minus two standard deviations (SD) was considered to have stunting. We linked factors relating to anaemia and stunting using a multivariate joint model under the scope of the generalized linear mixed model (GLMM).

RESULTS

The prevalence of anaemia and stunting in children younger than 5 years were 51% and 43% respectively. The multivariate results revealed a strong association between anaemia and stunting. In addition, maternal education, urban vs. rural residence, wealth index and childbirth weight significantly impacted childhood stunting or malnutrition, while having fever and/or diarrhoea was linked to anaemia. Lastly, age was shown to have a significant effect on both stunting and anaemia.

CONCLUSION

Anaemia and stunting or malnutrition showed linked longitudinal trajectories, suggesting both conditions could lead to synergetic improvements in overall child health. Demographic, socio-economic, and geographical characteristics were also important drivers of stunting and anaemia in children younger than 5 years. Thus, children living in similar resources settings as Lesotho could benefit from coordinated programs designed to address both malnutrition and anaemia.

Prevalence and Triggering Factors of Childhood Anemia: An Application of Ordinal Logistic Regression Model

INTRODUCTION

Anemia is indeed a significant risk factor for children's health as it affects growth retardation and has severe short and prolonged effects that follow in morbidity and death. Notwithstanding such ways to tackle anemia, the prevalence remains high in India and poses a severe public health concern.

OBJECTIVES

The primary focus of this study was to find the prevalence and to determine the factors associated with the anemia of children under five years of age in India. Problem Statement. The increasing prevalence of childhood anemia and the life-threatening consequences for millions of children in India are a major concern. Knowing the relevant associated factors with childhood anemia is essential to reduce the frequency and severity level. Study design. For analysis purposes, this study utilized a cross-sectional study design. Methodology. Using the Indian Demographic and Health Survey 2015-16 data, we used chi-squared and gamma tests to find the association. Then, we utilized multinomial logistic regression and ordinal logistic regression to find the better model and the influencing factors of anemia in India.

RESULTS

In our study, we have found that children with highly educated mothers were 36.7% less likely (OR = 0.633, P ≤ 0.001, 95% CI: 0.608, 0.658) to be higher anemic than the children with not educated mother. Children with moderate and severe anemic mothers were 163.3% (OR = 2.633, P ≤ 0.001, 95% CI: 2.565, 7.704) more likely to be higher anemic than the children with not anemic mother. Not stunting children were 21.9% (OR = 0.781, P ≤ 0.001, 95% CI: 0 .764, 0.797) less likely to be higher anemic than the stunting children. Children aged 36-59 months were 73.9% (OR = 0.361, P ≤ 0.001, 95% CI: 0.353, 0.369) less likely to be higher anemic than the children aged 6-24 months. Again, the ACI value revealed that ordinal logistic regression was a better-fitted model for these data.

CONCLUSION

and contribution. The variables such as stunting, underweight, wasting, child age, size of the child, and source of drinking water were the most critical indicators for child anemia in India. In summary, our study result indicated the major socioeconomic and demographic factors associated with childhood anemia in India, which can help the policymaker to take quick decision to reduce the severity level.

Prevalence of childhood anaemia in Brazil: still a serious health problem: a systematic review and meta-analysis

OBJECTIVE

To estimate the prevalence of anaemia in Brazilian children up to 83·9 months old.

DESIGN

Systematic review and meta-analysis, using databases PubMed, Scopus, SciELO, Lilacs, Google Scholar, Periódicos Capes, Arca, Biblioteca Virtual em Saúde, Microsoft Academic Search and Cochrane Library using search terms: anaemia, prevalence, child and Brazil. PROSPERO Registration number: CRD42020208818.

SETTING

Cross-sectional, cohort, case-control and intervention studies published between 2007 and 2020 were searched, excluding those who assessed children with an illness or chronic condition. The main outcome was anaemia prevalence. Random effects models based on the inverse variance method were used to estimate pooled prevalence measures. Sensitivity analyses removed studies with high contribution to overall heterogeneity.

PARTICIPANTS

From 6790 first screened, 134 eligible studies were included, totalling 46 978 children aged zero to 83·9 months analysed, with adequate regions representativeness.

RESULTS

Pooled prevalence of anaemia was 33 % (95 % CI 30, 35). Sensitivity analyses showed that withdrawal of studies that contributed to high heterogeneity did not influence national average prevalence.

CONCLUSIONS

Childhood anaemia is still a serious public health problem in Brazil, exposing 33 % of Brazilian children to the anaemia repercussions. The main limitation of the study is the estimation of national prevalence based on local surveys, but a large number of studies were included, with representation in all regions of the country, giving strength to the results. In Brazil, more public policies are needed to promote supplementation, fortification and access to healthy eating to reduce the high level of anaemia among children.

Prevalence and predictors of birth preparedness and complication readiness in the Kassena-Nankana district of Ghana: an analytical cross-sectional study

OBJECTIVES

To assess birth preparedness and complication readiness (BPACR) and associated factors among mothers who had given birth in the past 12 months prior to the study.

DESIGN

An analytical cross-sectional study.

SETTING

The study was carried out in the rural areas of Kassena-Nankana district located in the Upper East Region of Ghana.

PARTICIPANTS

The study population comprised 600 postpartum women who had delivered within the last 12 months prior to the study.

PRIMARY OUTCOME MEASURE

The primary outcome measure was BPACR.

RESULTS

The prevalence of BPACR among recently delivered women was very low as less than 15% were able to mention at least three of the five basic components of birth preparedness/complication readiness that were fulfilled. After adjustment for confounding effect using multivariable logistic regression analysis, high educational level (adjusted OR (AOR)=3.40 (95% CI: 1.88 to 6.15)), better knowledge about obstetric danger signs during pregnancy (AOR=4.88 (95% CI: 2.68 to 8.90)), older women (≥35 years) (AOR=2.59 (95% CI: 1.11 to 6.02)), women of low household wealth index (AOR=4.64 (95% CI: 1.97 to 10.91)) and women who received lower content of antenatal care services (AOR=3.34 (95% CI: 1.69 to 6.60)) were significant predictors of BPACR.

CONCLUSION

This study concludes that BPACR practices were low. High educational attainment of the woman, having adequate knowledge about obstetric danger signs during pregnancy, older women (≥35 years) and women of low household wealth index were significant predictors of BPACR. The predictors identified should be given high priority by health authorities in addressing low prevalence of BPACR.

Identification of Factors Influencing Anemia among Children Aged 6-59 Months in Ethiopia Using Ethiopia Demographic and Health Survey 2016 Data

Background

Anemia is the most common nutritional problem and a widespread micronutrient-deficiency disorder on a global scale. In Ethiopia, childhood anemia is highly prevalent and a major public health concern. This study aimed to identify factors associated with anemia among children aged 6–59 months in Ethiopia.

Methods

Data weres extracted from the 2016 Ethiopia Demographic and Health Survey (EDHS). We found records for 8,603 children aged 6–59 months in the data set. After 448 had been excluded due to incomplete records, 8,155 children were included in the final analysis. Pearson’s χ² was used to assess associations between each factor and categorical outcome variables. Multivariate logistic regression analyses were done to determine factors associated with anemia, and significant associations were declared at p≤0.05 for the final model.

Results

More than half (51.5%) the children were male and the overall mean age was 31.85±15.66 months. Mean hemoglobin concentration was 10.37±17.55 g/dL. The overall prevalence of anemia was 56.6%: 3.7%, 30.4%, and 22.5% severe, moderate, and mild anemia, respectively. Increased child age, decreased maternal age, lowest rung on wealth index, mother living alone, mother engaged in outside work, increased birth order, decreased birth interval, one antenatal care visit, severe stunting, and severe underweight were significantly associated with anemia.

Conclusion

The prevalence of anemia in this study was the highest of all EDHS reports. It had increased since the preceding report (EDHS 2011), and remains the main public health concern in Ethiopia. Comprehensive intervention strategies should be put in place and tailored to different levels of government (national, regional, and district) including household- and individual-level interventions for combating childhood anemia by focusing on the identified risk factors.

Hematological Abnormalities and Associated Factors Among Undernourished Under-Five Children Attending University of Gondar Specialized Referral Hospital, Northwest Ethiopia

Introduction

The hematopoietic system is one of the systems which can be affected by malnutrition, leading to impaired production of all blood cell lines. Undernourished children with hematological abnormalities like anemia are at higher risk of mortality. Therefore, this study aimed at determining the magnitude and associated factors of hematological abnormalities among undernourished under-five children attending at the University of Gondar Specialized Referral Hospital, Northwest Ethiopia.

Methods and Materials

An institution-based cross-sectional study was conducted on a total of 251 undernourished under-five children at University of Gondar Specialized Referral Hospital from January to May 2020. A convenient sampling technique was employed to select study participants. Data were collected using a pretested structured questionnaire. Blood samples were collected for complete blood count which were determined by Sysmex KX-21N analyzer. Stool sample was processed via direct wet mount. Thin and thick blood films were examined to assess malaria parasite. The data were entered to EpiData version 4.6.0.0 and analyzed using SPSS version 23 software. Bi-variable and multi-variable binary logistic regression model were fitted to identify factors associated with hematological abnormalities. A p-value <0.05 in the multivariable analysis was considered as statistically significant.

Results

The overall magnitude of anemia, leukocytosis, thrombocytosis, thrombocytopenia, and leukopenia was 53.4%, 26.7%, 23.9%, 8%, and 2.8%, respectively. Being male, age 6-23 months, high birth order, intestinal parasite infection, edema, not eating vegetables and fruits, and paternal occupation were found to be associated with anemia. Only the age of a child was associated with leukocytosis in undernourished children.

Conclusion

The current study demonstrated the predominant existence of anemia, leukocytosis, and thrombocytosis among undernourished under-five children. Therefore, early diagnosis, monitoring and setting intervention strategies for anemia especially among children under two years old are required to prevent further complication.

Prevalence of Anemia and Associated Factors among Infants and Young Children Aged 6-23 Months in Debre Berhan Town, North Shewa, Ethiopia

Background

Anemia is a problem of both the developed and developing world, which occurs in all age groups of the population. Half of the anemia cases are due to iron deficiency and affects physical growth and mental development. Nevertheless, there is a scarcity of information about anemia and associated factors among infants and young children aged 6 to 23 months in low-income countries like Ethiopia.

Objective

The aim of this study was to assess the prevalence of anemia and associated factors among infants and young children aged 6–23 months.

Methods

A community-based cross-sectional study design was used among 531 mothers/caregivers-children pairs in Debre Berhan Town, North Shewa, Ethiopia, from February 1 to March 2, 2018. The cluster sampling technique was used to select the study participants. Sociodemographic data were collected from mothers/caregivers using pretested structured questionnaires. Hemoglobin levels were measured using a HemoCue analyzer machine (HemoCue® Hb 301, Ängelholm, Sweden). All relevant data were described using descriptive statistics such as frequencies, proportions, mean, and standard deviation. Odds ratio and 95% CI were estimated using binary logistic regression to measure the strength of the association between anemia and explanatory variables. The level of statistical significance was declared at P < 0.05.

Results

The overall prevalence of anemia was 47.5% (95% CI: 43.1–51.4%) of which 18.3% were mildly anemic, 25% were moderately anemic, and 4.1% were severely anemic. In multivariable logistic regression analysis, household food insecurity (AOR = 2.7, 95% CI: 1.6–4.5), unmet minimum dietary diversity (AOR = 2.5, 95% CI: 1.4–4.3), stunting (AOR = 2.3, 95% CI: 1.2–4.3), and underweight (AOR = 2.7, 95% CI: 1.4–5.4) positively associated with anemia while having ≥4 antenatal care visits (AOR = 0.5, 95% CI: 0.3–0.9) and met minimum meal frequency (AOR = 0.25, 95% CI: 0.14–0.45) had a protective effect against anemia.

Conclusion

Generally, the study showed that anemia was a severe public health problem among infants and young children in the study setting. Antenatal care visit, meal frequency, dietary diversity, underweight, stunting, and food insecurity significantly associated with anemia. Therefore, efforts should be made to strengthen infant and young child feeding practices and antenatal care utilization and ensure household food security, thereby improving the nutritional status of children.

Magnitude, Severity, and Associated Factors of Anemia among Under-Five Children Attending Hawassa University Teaching and Referral Hospital, Hawassa, Southern Ethiopia, 2016

Background

Anemia is a widespread public health problem associated with increased risk of morbidity and mortality. Infants, under-5-year-old children, and pregnant women have greater susceptibility to anemia. The magnitude and associated risk factors for anemia vary in different settings. The study aimed to assess the magnitude, severity, and associated factors of anemia at Hawassa University Teaching and Referral hospital, Hawassa, southern Ethiopia.

Methods

In a hospital-based cross-sectional study, a total of 422 under-five children were included. Sociodemographic data and other predisposing factors were collected by structured questionnaire. Venous blood samples were collected and analyzed for hemoglobin determination using a Cell-Dyn 1800 automated analyzer. Stool samples were collected and processed using direct wet mount and formol-ether concentration method to detect intestinal parasites. Data were entered and analyzed using SPSS version 20 statistical packages. Binary and multiple logistic regressions were computed to assess factors associated with anemia. p value less than 0.05 was taken as statistically significant.

Result

The overall prevalence of anemia was found to be 41.7%. The mean hemoglobin level was 10.59 g/dl. Anemia was of mild, moderate, and severe type in 6.6%, 19%, and 16.1% of the children, respectively. Children in the age group 6-23 months (AOR = 2.04 (95% CI: 1.13, 3.69)), and mothers having no formal education (AOR = 1.73 (95% CI: 0.99, 3.02)) were identified as associated factors for anemia.

Conclusion

The prevalence of anemia among the study subjects was 41.7% indicative of the fact that anemia is an important public health problem. It was associated with the child's age, residence, mother's education level, and intestinal parasite (Ascaris lumbricoides). It clearly indicates that there should be well integrated public health interventions to improve the health status that needs to be prioritized to prevent anemia among children under five years of age.

Association between anemia and household water source or sanitation in preschool children: the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project

BACKGROUND

The associations between anemia and household water source and sanitation remain unclear.

OBJECTIVES

We aimed to assess the associations between anemia and household water source or sanitation in preschool children (PSC; age 6-59 mo) using population-based surveys from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project.

METHODS

We analyzed national and subnational data from 21 surveys, representing 19 countries (n = 35,963). Observations with hemoglobin (Hb) and ≥1 variable reflecting household water source or sanitation were included. Anemia was defined as an altitude-adjusted Hb concentration <110 g/L. Household water source and sanitation variables were dichotomized as "improved" or "unimproved." Poisson regressions with robust variance estimates were conducted for each survey, adjusting for child sex, age, household socioeconomic status, maternal education, and type of residence.

RESULTS

Access to an improved water source and improved sanitation ranged from 29.9% (Burkina Faso) to 98.4% (Bangladesh, 2012), and from 0.2% (Kenya, 2007) to 97.4% (Philippines), respectively. Prevalence of anemia ranged from 20.1% (Nicaragua) to 83.5% (Bangladesh, 2010). Seven surveys showed negative associations between anemia and improved sanitation. Three surveys showed association between anemia and improved water, with mixed directions. Meta-analyses suggested a protective association between improved household sanitation and anemia [adjusted prevalence ratio (aPR) = 0.88; 95% CI: 0.79, 0.98], and no association between improved household water and anemia (aPR = 1.00; 95% CI: 0.91, 1.10). There was heterogeneity across surveys for sanitation (P < 0.01; I2 = 66.3%) and water (P < 0.01; I2 = 55.8%).

CONCLUSIONS

Although improved household sanitation was associated with reduced anemia prevalence in PSC in some surveys, this association was not consistent. Access to an improved water source in general had no association with anemia across surveys. Additional research could help clarify the heterogeneity between these conditions across countries to inform anemia reduction programs.

Intestinal parasitosis, anaemia and risk factors among pre-school children in Tigray region, northern Ethiopia

BACKGROUND

Intestinal parasitic infections (IPIs) and anaemia are major health problems. This study assessed the prevalence of intestinal parasitic infections, anaemia and associated factors among pre-school children in rural areas of the Tigray region, northern Ethiopia.

METHODS

A community based cross-sectional study was conducted among 610 pre-school children in rural communities of Northern Ethiopia from June 2017 to August 2017. Stool specimens were examined for the presence of trophozoites, cysts, oocysts, and ova using direct, formal-ethyl acetate concentration, Kato-Katz, and Ziehl-Neelsen techniques. Haemoglobin was measured using a HemoCue spectrometer.

RESULTS

Among the 610 participating pre-school children in the study, the prevalence of IPIs and anaemia were 58% (95% conference interval (CI): 54.1-61.9%) and 21.6% (95% CI: 18.5-25.1%), respectively. Single, double, and triple parasitic infections were seen in 249 (41, 95% CI: 37-45%), 83 (14, 95% CI: 11-17%), and 22 (3.6, 95% CI: 2.4-5.4%) children, respectively. Of the seven intestinal parasitic organisms recorded from the participants, Entamoeba histolytica/dispar was the most prevalent 220 (36.1%) followed by Giardia lamblia 128 (20.1%), and Hymenolepis nana 102 (16.7%). Mixed infections were common among G. lamblia, E. histolytica/dispar and Cryptosporidium spp. oocyst. Intestinal parasitic infection prevalence increased from 47% in children aged 6-11 months to 66% in those aged 48-59 months; the prevalence ratio (PR) associated with a one-year increase in age was 1.08 (95% CI: 1.02-1.14, p = 0.009). Age-adjusted prevalence was higher in children who had been dewormed (PR = 1.2; 95% CI: 1.00-1.4, p = 0.045), and lower in households having two or more children aged under five (PR = 0.76, 95% CI: 0.61-0.95, p = 0.015). Anaemia rose from 28% in children aged 6-11 months to 43% in those aged 12-23 months, then fell continuously with age, reaching 7% in those aged 48-59 months. Age adjusted, anaemia was more prevalent in households using proper disposal of solid waste (PR = 1.5, 95% CI: 0.1-2.10, p = 0.009) while eating raw meat (PR = 0.49, 95% CI: 0.45-0.54, p = 0.000), any maternal education (PR = 0.64 95% CI: 0.52-0.79, p = 0.000), and household water treatment (PR = 0.75, 95% CI: 0.56-1.0, p = 0.044) were associated with lower prevalence of anaemia.

CONCLUSIONS

More than half of the children were infected with intestinal parasites, while anaemia prevalence was concentrated in the 12-23 month age group. This study has identified a number of potentially modifiable risk factors to address the significant prevalence of IPIs and anaemia in these children. Improvements in sanitation, clean water, hand hygiene, maternal education could address both short and long-term consequences of these conditions in this vulnerable population.

Prevalence of anaemia in Brazilian children in different epidemiological scenarios: an updated meta-analysis

OBJECTIVE

To update the estimation of the prevalence of anaemia in Brazilian children according to four different epidemiological scenarios.

DESIGN

A new systematic review was conducted with a meta-analysis of the results published between 2007 and May 2019. Literature search was carried out in the PubMed and LILACS databases using keywords anaemia, child and Brazil. A total of thirty-seven articles (17 741 children) were selected and categorised according to the origin of their respective samples: childcare centres (Childcare; n 13 studies/2697 individuals), health services (Services; n 4/755), populations with social inequities (Inequities, n 7/6798) and population-based studies (Populations; n 13/7491). Assuming a prevalence of 20·9 % as reference (Health National Survey; n 3455), the combined prevalence ratios (PR) were calculated. A random-effects model was used.

PARTICIPANTS

Brazilian children 6-60 months of age.

RESULTS

The prevalence of anaemia, by scenario, was: Childcare 24·8 % (PR 1·06; 95 % CI 0·81, 1·40); Services 39·9 % (PR 1·76, 95 % CI 1·33, 2·35); Inequities 51·6 % (PR 2·02, 95 % CI 1·87, 2·18); and Populations 35·8 % (PR 1·42, 95 % CI 1·23, 1·64). Therefore, the values were all higher than the national prevalence; the Inequities had the highest prevalence, and only Childcare did not reach statistical significance. Concerning the previous meta-analysis, there was a reduction in anaemia prevalence in all scenarios: -52·3, -33·7, -22·4 and -10·7 %, respectively.

CONCLUSIONS

Compared to the situation revealed in the previous meta-analysis, anaemia, although observed to a lesser extent, remains an important public health problem in the different scenarios analysed, especially for children living in Inequities. Access to Childcare mitigates the risk for this condition.

Determinants of Anemia among Children Aged 6–59 Months in Ethiopia: Further Analysis of the 2016 Ethiopian Demographic Health Survey

Background. Anemia among children is a global public health problem. The burden is high in developing countries including Ethiopia. Although there are some studies about anemia among children, there is a dearth of information about factors associated with anemia in Ethiopia. Therefore, this analysis was performed to identify factors associated with anemia among children aged 6–59 months in Ethiopia. Methods. We used the 2016 Ethiopian Demography and Health Survey (EDHS) data. EDHS was a community-based, cross-sectional study conducted from January 18, 2016 to June 27, 2016. The 2016 EDHS selected the participants using a two-stage stratified cluster sampling technique. A total of 8,462 children aged 6–59 months were included for this analysis. Both descriptive and logistic regression analyses were performed using Stata version14. A P value less than 0.05 at 95% confidence interval was set to test the statistical significance. Results. The analysis indicated that about 58% (95% CI: 55.1, 60.1) of children aged 6–59 months were anemic. Of those, 29.4% and 3.1% had moderate and severe anemia, respectively. The analysis revealed that stunted (AOR = 0.135, 95% CI: 1.13, 1.62) and underweight (AOR = 1.27, 95% CI: 1.04, 1.55) children had higher odds of being anemic. Besides, children aged 6–23 months (AOR = 1.39, 95% CI: 1.06, 1.82), 24–42 months of age (AOR = 1.26, 95% CI: 1.05, 1.51), and those with fever (AOR = 1.34, 95% CI: 1.07, 1.67) had higher odds of being anemic. Similarly, children from anemic mothers (AOR = 1.86, 95% CI: 1.58, 2.18) and poor households (AOR = 1.35, 95% CI: 1.09, 1.67) were at a higher risk of anemia. Children from households with large family sizes (AOR = 1.29, 95% CI: 1.03, 1.60), young mothers (15–24 years of age (AOR = 1.39, 95% CI: 1.06, 1.82) and 25–34 years of age (AOR = 1.26, 95% CI: 1.05, 1.51)), and developing regions (AOR = 1.44, 95% CI: 1.03, 2.02) also had higher odds of developing anemia. Conclusion. The overall prevalence of anemia among children aged 6–59 months in Ethiopia was high. Malnourished children (stunting and underweight); children with fever; children from anemic, uneducated, and young mothers; and children from large and poor families had higher odds to develop anemia. Therefore, preventing childhood illnesses and maternal anemia should be strengthened to reduce anemia among children.

Recomendação e uso de sulfato ferroso em crianças de 12 e 24 meses de idade: avaliação da coorte de nascimentos de Pelotas, RS, de 2015

RESUMO: Objetivo: Verificar a prevalência e os fatores associados à recomendação de uso de ferro a crianças aos 12 e aos 24 meses de idade. Metodologia: Todas as crianças nascidas nas maternidades de Pelotas em 2015 foram elegíveis para a coorte. Os desfechos foram a recomendação de uso de sulfato ferroso por profissional de saúde e a respectiva utilização. Resultados: A coorte acompanhou 4.275 crianças. Aproximadamente 65% receberam recomendação de suplementação de ferro até 12 meses. Destas, 68,8% fizeram a utilização recomendada. Dos 12 aos 24 meses, 39,4% das crianças receberam recomendação de suplementação de ferro e 26,2% fizeram o uso recomendado. Aos 12 meses, após ajuste, permaneceram associadas com recomendação de uso de ferro: maior escolaridade, maior renda, menor paridade e baixo peso ao nascer. Aos 24 meses, após ajuste, observou-se maior recomendação às mães com menor paridade e às crianças com baixo peso ao nascer. Conclusão: Houve baixa recomendação e baixa utilização de ferro. Esses achados são preocupantes diante da alta prevalência de anemia em crianças na faixa etária estudada. A baixa recomendação de profilaxia de ferro a crianças até 24 meses de idade, assim como a baixa utilização entre aquelas que receberam a orientação de uso refletem a necessidade de ações coordenadas entre profissionais de saúde e de ampliação do conhecimento entre as mães para possibilitar maior alcance dessa importante política pública.

Disparities in the prevalence and risk factors of anaemia among children aged 6–24 months and 25–59 months in Ethiopia

Despite global efforts made to address anaemia, the prevalence remains high in most Sub-Saharan African countries. In Ethiopia, anaemia poses a very strong public health concern. The purpose of the present study was to examine the key risk factors related to anaemia among children aged 6–24 months (younger age group) and 25–59 months (older age group). We used the 2016 Ethiopian Demographic and Health Survey data, collected from 11 023 mothers with under five children. Ordered logistic regression modelling was used for assessing risk factors of childhood anaemia. The results suggest that the prevalence of anaemia was 72 % in the younger and 49 % in the older age groups. The risk factors for anaemia in the younger age group were morbidity (odds ratio (OR) 1⋅77; CI 1⋅21, 2⋅60), having no piped water source (OR 1⋅76; CI 1⋅07, 3⋅01) and no toilet facility (OR 1⋅60; CI 1⋅07, 2⋅38). The key risk factors for anaemia in the older age group were no micronutrient intake (OR 1⋅69; CI 1⋅23, 2⋅31), having a young mother (15–24 years old) (OR 1⋅35; CI 0⋅84, 1⋅91) and a non-working mother (OR 1⋅50; CI 1⋅15, 1⋅96). Anaemia also varied by region, place of residence and economic factors. Multiple factors contributed to the high prevalence of anaemia. Given the structural problem that the country has intervention strategies should consider the unique characteristics of regions and rural residences where the prevalence of anaemia is above the national average.

Under nutrition, maternal anemia and household food insecurity are risk factors of anemia among preschool aged children in Menz Gera Midir district, Eastern Amhara, Ethiopia: a community based cross-sectional study

BACKGROUND

In Ethiopian, the prevalence of anemia among preschool aged children widely varied across regions. Since anemia adversely affects the cognitive and physical development of the children, it is important to determine its burden for implementing appropriate measurements. Therefore, this study was aimed at determining the anemia prevalence and associated factors among preschool aged children.

METHOD

A community based cross-sectional study was conducted on a total of 432 preschool children in Menz Gera Midir district from January to May, 2017. A multi stage sampling procedure was applied to select the target groups. Hemocue analyzer for Haemoglobin determination; anthropometric measurements for assessment nutritional status, structured questionnaires for socio-demographic and economic variables were used for data collection. The morphological appearance of red blood cell was assessed microscopically to determine type of anemia. Descriptive statistics were employed to summarize the data and binary logistic regression was used for inferential statistics. A p value less than 0.05 was considered as statistically significant.

RESULT

The overall prevalence of anemia was 123 (28.5%); of which 38 (30.9%) and 85 (69.1%) were moderate and mild, respectively. Morphologically about 50.4, 37.4 and 12.2% were microcytic hypochromic, normocytic normochromic and macrocytic anemias, respectively. Child age 6-11 months (COR: 5.67, 95% CI: 2.2, 14.86), child age 12-23 months (COR: 5.8, 95% CI: 2.3, 14.7), wasting (COR: 3.5, 95% CI: 1.2, 9.8), stunting (COR: 3.8, 95% CI: 1.92, 7.77), underweight (COR: 2.12, 95% CI: 1.07, 4.38), MUAC measurement below 13 cm (COR: 5.6, 95% CI: 2.83, 11.15), household headed by female (COR: 3.24, 95% CI: 1.1, 9.63), maternal anemia (COR: 4, 95% CI: 2.2, 7.23) and household food insecurity (COR: 2.12, 95% CI: 1.09, 4.12) were significantly associated with anemia.

CONCLUSION

The prevalence of anemia among the children was found to be high and associated with child age group, child nutritional status, house hold headed by female, maternal anemia and household food insecurity. Further studies on nutritional anemia, community based nutritional education, iron supplementation to children at risk should be promoted.

Factors influencing childhood anaemia in Bangladesh: a two level logistic regression analysis

BACKGROUND

Anemia is not only a major public health problem among children in developing countries, it is also an important predictor for their future growth and development. The objective of this study was to identify possible factors associated with anemia among pre-school children in Bangladesh after removing a cluster effect of the population, and to determine the prevalence of this condition.

METHODS

Data for this study was extracted from the 2011 Bangladesh Demographic and Health Survey (BDHS-2011). In this survey, data was collected using a two-stage stratified cluster sampling approach. The chi-square test and a two-level logistic regression model were used for further analysis.

RESULTS

Data from 2231 children aged 6-59 months were included for analysis. The prevalence of child anemia was noted to be 52.10%. Among these anemic children, 48.40% where from urban environment and 53.90% were from rural areas. The prevalence of mild, moderate and severe anemia among children was 57.10, 41.40 and 1.50% respectively. The two-level logistic regression model revealed that the following factors were associated with childhood anemia: children of anemic mothers (p < 0.01), undernourished children (p < 0.05), younger children (age < 2 years) (p < 0.01) and children from poor family (p < 0.05). Lastly, anemia was more common among children living in Barisal and Rangpur divisions compared to those from Dhaka division (p < 0.01), and among non-Muslims than Muslim (p < 0.05).

CONCLUSIONS

Our study showed that prevalence of anemia among pre-school children in Bangladesh was very high (52.10%). We noted that young children of anemic mothers, from poor families, and being undernourished were at higher risk of developing anemia. Since most of these risk factors were related to socioeconomic conditions, they were potentially modifiable. Therefore, our findings may be useful for the health authorities to identify children at risk for remedial action and to plan for preventive measures.

Risk Factors of Anaemia among Children under Five Years in the Hohoe Municipality, Ghana: A Case Control Study

Background

Anaemia is one of the major causes of death among children under five years in Ghana. We examined the risk factors of anaemia among children under five years in the Hohoe Municipality, Ghana.

Methods

This facility-based matched case control study recruited 210 children (70 cases and 140 controls) aged 6 to 59 months. Stratified and simple random sampling techniques were used to select mothers attending Child Welfare Clinic (CWC) for the screening of their children. Data were collected using a semistructured questionnaire. Finger prick blood was collected to estimate the haemoglobin (Hb) level and thick film was prepared to determine malaria parasitaemia. Axillary temperature was measured using an +electronic thermometer and anthropometric measurements were done using a weighing scale and inelastic tape measure. Continuous variables were presented as means and standard deviations and categorical variables as frequencies and proportions. Conditional logistic regression was used to determine the strength of association between the dependent and the independent variables. Statistical significance was considered at p value of <0.05.

Results

The prevalence of anaemia was high (53.8%), while children whose mothers received iron supplementation during pregnancy were 7.64 times more likely to be anaemic compared with those who did not [AOR=7.64 (95% CI:1.41-41.20.93); p=0.018]. Children with poor dietary diversity were 9.15 times more likely to have anaemia [AOR=9.15 (95% CI: 3.13-26.82); p< 0.001]; and children whose mothers were farmers and traders were 83% [AOR = 0.17 (95% CI: 0.05-0.60); p=0.006] and 79% [AOR=0.21 (95% CI: 0.06-0.74); p=0.014], respectively, less likely to have anaemia.

Conclusion

The biologic, intermediate, and underlying factors that were significantly associated with anaemia comprised maternal iron supplementation, poor dietary diversity, farmers, and traders. Given that iron supplementation during pregnancy did not protect children against anaemia, we recommend the child's nutritional dietary diversity is encouraged.

Prevalence and correlates of anemia among children aged 6-23 months in Wolaita Zone, Southern Ethiopia

BACKGROUND

Anemia, the world's most common micro-nutrient deficiency disorder, can affect a person at any time and at all stages of life. Though all members of the community may face the problem, children aged 6-23 months are particularly at higher risk. If left untreated, it adversely affects the health, cognitive development, school achievement, and work performance. However, little was investigated among young children in Sub-Saharan countries including Ethiopia. This research aimed to investigate its magnitude and correlates to address the gap and guide design of evidence based intervention.

METHODS

A community-based cross-sectional study was conducted from May -June 2016 in rural districts of Wolaita Zone. Multi-stage sampling technique was applied and 990 mother-child pairs were selected. Socio-demography, health and nutritional characteristics were collected by administering interview questionnaire to mothers/care-givers. Blood samples were taken to diagnose anemia by using HemoCue device, and the status was determined using cut-offs used for children aged 6-59 months. Hemoglobin concentration below 11.0 g/dl was considered anemic. Data were analyzed with Stata V14. Bivariate and multivariable logistic regressions were applied to identify candidates and predictor variables respectively. Statistical significance was determined at p-value < 0.05 at 95% confidence interval.

RESULTS

The mean hemoglobin level of children was 10.44±1.3g/dl, and 65.7% of them were anemic. Among anemic children, 0.4% were severely anemic (<7.0g/dl), while 28.1% and 37.2% were mildly (10.0-10.9g/dl) and moderately (7.0-9.9g/dl) anemic, respectively. In the multivariable analysis, having maternal age of 35 years and above (AOR = 1.96), being government employee (AOR = 0.29), being merchant (AOR = 0.43) and 'other' occupation (AOR = 3.17) were correlated with anemia in children in rural Wolaita. Similarly, receiving anti-helminthic drugs (AOR = 0.39), being female child (AOR = 1.76), consuming poor dietary diversity (AOR = 1.40), and having moderate household food insecurity (AOR = 1.72) were associated with anemia in rural Wolaita.

CONCLUSION

A large majority of children in the rural Wolaita were anemic and the need for proven public health interventions such as food diversification, provision of anti-helminthic drugs and ensuring household food security is crucial. In addition, educating women on nutrition and diet diversification, as well as engaging them with alternative sources of income might be interventions in the study area.

Prevalence of Anemia in Children from Latin America and the Caribbean and Effectiveness of Nutritional Interventions: Systematic Review and Meta⁻Analysis

Anemia affects 1.62 billion people worldwide. Latin America and the Caribbean (LAC) comprise several developing countries where children are a population at risk. This systematic review and meta-analysis aimed to estimate the prevalence of anemia in this population. Electronic databases, reference lists, and websites of health ministries were searched until December 2018. Stratified analyses were performed using RevMan5.3 to estimate the overall prevalence of anemia in preschool and school-age children. The effectiveness of nutritional interventions was also evaluated. We included 61 studies from the 917 reviewed, which included 128,311 preschool- and 38,028 school-age children from 21 LAC countries. The number of anemic children was 32.93% and 17.49%, respectively, demonstrating a significant difference according to age (p < 0.01). No difference was observed by gender and only school-age children from low/very low socioeconomic status (SES) (25.75%) were more prone to anemia than those from middle SES (7.90%). It was not a concern in the Southern Cone but constituted a serious public health problem in the Latin Caribbean. Nutritional interventions reduced the prevalence from 45% to 25% (p < 0.01). Anemia is still a public health problem for children in LAC countries. National surveys should include school-age children. Further nutritional interventions are required to control anemia.

[Challenges of inter-sector collaboration in public policies: the dilemma between nutritional supplementation and the promotion of healthy eating in schools]

The study aimed to identify and analyze the development of inter-sector arrangements between the health and education sectors in the framework of the implementation of the NutriSUS strategy in a municipality (county) in the state of Rio de Janeiro, Brazil. The study was conducted from March 2015 to March 2017 and used policy analysis as the analytical reference, with the following analytical dimensions: operational design; ideas on the nutritional supplementation; institutional context; and inter-sector collaboration. Semi-structured interviews were held with health professionals and administrators and schoolteachers and school system administrators at the three levels of government, in addition to document analysis. The NutriSUS strategy was implemented in five preschool units and required establishing agreements between health professionals and teachers that were affected by the following: the design based on the preventive approach to diseases with emphasis on action by the health sector; mechanisms of induction and convergence of interests between the federal and local governments; management mechanisms and institutional spaces including different stages in the implementation process, that is, the NutriSUS management centered in the health sector but operationalized in the school system; and the intersection between NutriSUS and the National School Food Program which increased the visibility of competing concepts concerning supplementation as a preventive strategy and different approaches to promote healthy eating. Thus, the factors identified by the study challenge the development of inter-sector collaboration oriented by shared processes in the entire chain of implementation of inter-sector programs for schools.

Factores asociados a las concentraciones de hemoglobina en preescolares

Resumen El presente estudio buscó identificar en niños preescolares la asociación de las concentraciones de hemoglobina con características socio-ambientales, maternas, biológico-nutricionales y las condiciones de salud; así como con las concentraciones séricas de zinc y retinol. Estudio transversal con muestra de 335 individuos, representativa de los niños de jardines infantiles del municipio de Campina Grande, Paraíba. En los 294 niños estudiados, el modelo ajustado mostró menores concentraciones de hemoglobina en casos de tipo de casa diferente de ladrillo; ausencia de red de escoto; colecta no pública de la basura; no tratamiento del agua para beber; dificultades maternas para leer, escribir o hacer cuentas; edad entre 9-24 meses; peso/edad < - 2 escore Z y problemas de salud en los últimos 15 días, bien como en casos de bajas concentraciones séricas de zinc y retinol. La multicausalidad de concentraciones inferiores de hemoglobina comprendió condiciones socio-ambientales y características materno-infantiles que refuerzan la importancia de medidas que prioricen los niños de menor edad, de madres con menor nivel educacional y con prejuicios en su peso, estado de salud y condición nutricional de otros micronutrientes importantes en el crecimiento.

Intra-household double burden of malnutrition in a North African nutrition transition context: magnitude and associated factors of child anaemia with mother excess adiposity

Objective

In the Middle East and North Africa region, the nutrition transition has resulted in drastic increases in excess adiposity, particularly among women, while some types of undernutrition remain prevalent, especially among pre-school children. We assessed the magnitude, nature and associated factors of the within-household co-occurrence of anaemia in children and excess adiposity in mothers.

Design

Cross-sectional survey using stratified two-stage random cluster sampling to survey households with women aged 20–49 years. BMI≥25·0 kg/m2 defined overweight and BMI≥30·0 kg/m2 obesity, while anaemia for children was defined as Hb<110 g/l. The associations between child anaemia and mother excess adiposity, and sociodemographic and lifestyle factors were estimated by multinomial regression.

Setting

Greater Tunis area, Tunisia, in 2009–2010.

Subjects

Children aged 6–59 months living with their 20–49-year-old mothers (437 child–mother pairs).

Results

The most prevalent double burden of malnutrition in child–mother pairs by far was the anaemic child and overweight mother (24·4 %; 95 % CI 20·1, 29·3 %). A significant proportion of pairs were anaemic child and obese mother (14·4 %; 95 % CI 11·0, 18·5 %). The co-occurrence of anaemia in child and excess adiposity in mother was neither synergetic nor antagonistic (P=0·59 and 0·40 for anaemia–overweight and anaemia–obesity, respectively). This double burden was more frequent among child–mother pairs with younger children, with mothers of higher parity and higher energy intakes.

Conclusions

The high prevalence of anaemic child and overweight or obese mother requires special attention e.g. through interventions which simultaneously target both types of malnutrition within the same household.

Anemia severity among children aged 6-59 months in Gondar town, Ethiopia: a community-based cross-sectional study

Background

Anemia is a public health problem affecting both developed and developing countries. Childhood anemia is associated with serious consequences including growth retardation, impaired motor and cognitive development, and increased morbidity and mortality. Hence, this study aimed at assessing the prevalence and factors associated with severity of anemia among children aged 6–59 months in Gondar town, northwest Ethiopia.

Method

A community-based cross-sectional study was conducted. A multi-stage sampling technique was employed to select study participants. Socio demographic and socioeconomic data were collected using a pre-tested structured questionnaire. Anthropometric measurements were taken as per WHO recommendation. Hemoglobin (Hb) concentration was measured using a portable HemoCue301 instrument (A Quest Diagnostic Company, Sweden). Mild anemia corresponds to a level of adjusted Hb of 10.0–10.9 g/dl; moderate anemia corresponds to a level of 7.0–9.9 g/dl, while severe anemia corresponds to a level less than 7.0 g/dl. Descriptive statistics were used to describe the study participants. Both bivariable and multivariable ordinal logistic regression were done, and proportional odds ratio (POR) with a 95% confidence interval (CI) was reported to show the strength of association. A p-value < 0.05 was considered statistically significant.

Result

Out of the total of 707 children included in this study, more than half (53.5%) of them were male. The median age of children was 30 months. Two hundred two (28.6%) of children were anemic: 124(17.5%) were mildly anemic, 73(10.3%) were moderately anemic, and 5 (0.7%) were severely anemic. The young age of the child, low frequency of child complementary feeding per day, primary maternal educational status, unmarried maternal marital status, and home delivery were factors associated with severity of childhood anemia.

Conclusion

Anemia among children aged 6–59 months in Gondar Town was a moderate public health problem. Improving access to education, providing regular health education about childcare and child feeding practices, strengthening the socioeconomic support for single-parent families and conducting regular community-based screening are recommended to reduce childhood anemia.

Male and undernourished children were at high risk of anemia in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Anemia is one of the global public health problems affecting more than one-third of the world population. It has been strongly associated with limited psychomotor development; and poor growth and performance in cognitive, social, and emotional function in children. Despite published data revealed that anemia is a public health problem among children in Ethiopia, there is no a pooled national estimate on the prevalence and associated risk factors of anemia.

METHODS

Published articles until December 31, 2017, were searched using comprehensive search strings through PubMed/Medline, EMBASE, SCOPUS, HINARI, Web of Science, Google Scholar and Google. Reference probing of published articles and hand searching were employed for grey literature. Two groups of review authors independently appraised the studies for eligibility and extracted the data. The quality of articles was assessed using Joana Brigg's institute critical appraisal checklist for prevalence and analytical studies. The pooled estimates were determined using random effect model. Heterogeneity between the included studies was assessed using the I2 statistics. Subgroup analysis was employed in the evidence of heterogeneity. Publication bias was assessed by visual inspection of the funnel plot and Egger's regression test statistic.

RESULTS

Of the total 871 articles retrieved, 34 articles which involved 61,748 children were eligible for meta-analysis. The overall pooled prevalence of anemia using random effect model was 31.14% (95% CI: 24.62, 37.66%). In subgroup analysis, the pooled prevalence of anemia was higher among preschool-aged children (44.17%; 95% CI: 37.19, 51.15%) than school-aged children (22.19%; 95% CI: 17.54, 26.83%). Furthermore, the odds of anemia was higher among children who were male (OR = 1.11; 95% CI: 1.03, 1.19), stunted (OR = 1.95; 95% CI: 1.52, 2.51), and wasted (OR = 2.05; 95% CI: 1.36, 3.10).

CONCLUSION

The pooled prevalence of anemia among children was high, indicating that it had been continuing to be a public health problem. Therefore, there is a need to design a comprehensive prevention and control strategies to reduce its burden.

Multilevel Analysis of Determinants of Anemia Prevalence among Children Aged 6-59 Months in Ethiopia: Classical and Bayesian Approaches

Background

Anemia is a widely spread public health problem and affects individuals at all levels. However, there is a considerable regional variation in its distribution.

Objective

Thus, this study aimed to assess and model the determinants of prevalence of anemia among children aged 6–59 months in Ethiopia.

Data

Cross-sectional data from Ethiopian Demographic and Health Survey was used for the analysis. It was implemented by the Central Statistical Agency from 27 December 2010 through June 2011 and the sampling technique employed was multistage.

Method

The statistical models that suit the hierarchical data such as variance components model, random intercept model, and random coefficients model were used to analyze the data. Likelihood and Bayesian approaches were used to estimate both fixed effects and random effects in multilevel analysis.

Result

This study revealed that the prevalence of anemia among children aged between 6 and 59 months in the country was around 42.8%. The multilevel binary logistic regression analysis was performed to investigate the variation of predictor variables of the prevalence of anemia among children aged between 6 and 59 months. Accordingly, it has been identified that the number of children under five in the household, wealth index, age of children, mothers' current working status, education level, given iron pills, size of child at birth, and source of drinking water have a significant effect on prevalence of anemia. It is found that variances related to the random term were statistically significant implying that there is variation in prevalence of anemia across regions. From the methodological aspect, it was found that random intercept model is better compared to the other two models in fitting the data well. Bayesian analysis gave consistent estimates with the respective multilevel models and additional solutions as posterior distribution of the parameters.

Conclusion

The current study confirmed that prevalence of anemia among children aged 6–59 months in Ethiopia was severe public health problem, where 42.8% of them are anemic. Thus, stakeholders should pay attention to all significant factors mentioned in the analysis of this study but wealth index/improving household income and availability of pure drinking water are the most influential factors that should be improved anyway.

Prevalence and temporal trend (2005-2015) of anaemia among children in Northeast Brazil

OBJECTIVE

Anaemia is the main nutritional deficiency in Brazil, and a prevention and control programme (National Program for Iron Supplementation) has been developed since 2005. Studies on the temporal evolution of anaemia prevalence contribute to assessment of the effectiveness of the actions undertaken. The present study aimed to identify the prevalence and temporal trend of anaemia in children.

DESIGN

Study based on two cross-sectional household surveys carried out in 2005 and 2015. Anaemia was defined as Hb<11 g/dl (HemoCue®). Trend analysis was performed using the prevalence ratio (PR), calculated by Poisson regression with a robust adjustment of the variance. Differences were significant when P<0·05 in both crude analyses and those adjusted for possible confounding factors (e.g. socio-economic, demographic and health variables).

SETTING

Alagoas, Brazil.

SUBJECTS

In total, 666 and 782 children in the first and second Alagoas State Health and Nutrition Survey, respectively (probabilistic samples).

RESULTS

In 2005 and 2015, anaemia prevalence was 45·1 and 27·4 %, respectively (-39·1 %; PR=0·61; 95 % CI 0·52, 0·70). In both surveys, children aged ≤24 months were more affected (P24 months (67·2 v. 40·7 %; 27·0 v. 19·3 %, respectively).

CONCLUSIONS

The prevalence of anaemia reduced significantly in the evaluated period. Thus, it may no longer be a severe public health problem but can instead be considered a problem of moderate magnitude. It remains, however, above the level considered acceptable according to WHO criteria. These results justify the implementation of prevention and control actions.

Indicadores de insegurança alimentar e nutricional associados à anemia ferropriva em crianças brasileiras: uma revisão sistemática

Resumo Objetivou-se revisar os indicadores de insegurança alimentar e nutricional associados à anemia ferropriva em crianças brasileiras menores de 5 anos. Realizou-se busca em bases eletrônicas (ScieLO, Lilacs, Medline), com seleção dos estudos pelos títulos, resumos e pela leitura na íntegra. Dos 1023 trabalhos analisados, 11 contemplaram os critérios de inclusão. Os resultados dos estudos retrataram que a anemia ferropriva em crianças brasileiras associou-se aos indicadores sociodemográficos e de saúde (sexo masculino, idade inferior aos 24 meses, filhos de mães adolescentes, infecções respiratórias, diarreias, baixa escolaridade materna, condição de trabalho dos pais, tempo de creche, ausência de saneamento básico, anemia materna, não uso de sulfato ferroso pela mãe e/ou criança e início tardio do pré-natal), indicadores nutricionais (baixo peso ao nascer, características da dieta como, hábito de ingerir leite próximo dos horários das refeições, baixo tempo de aleitamento materno exclusivo e total) e econômicos (baixa renda per capita). A insegurança alimentar e nutricional, analisada no presente estudo sob a óptica de diferentes indicadores, está associada à ocorrência de anemia ferropriva em crianças menores de 5 anos no Brasil.

Does Anaemia Have Major Public Health Importance in Children Aged 6-59 Months in the Duggina Fanigo District of Wolaita Zone, Southern Ethiopia?

BACKGROUND

Globally, a large number of children aged 6-59 months are affected by anaemia. In Ethiopia, like other developing countries, more than 40% of children under 5 years are affected by anaemia. Anaemia during infancy and childhood period is associated with poor health and impaired cognitive development, leading to reduced academic achievement and earning potential in their adult life. The aim of this research was to assess whether anaemia remained a major public health problem among children aged 6-59 months or not in Duggina Fanigo District of Wolaita Zone, South Ethiopia in 2016.

METHODOLOGY

A community-based cross-sectional study was conducted from February to March 2016, on 404 mothers with children aged 6-59 months who were selected through the systematic sampling method. Socio-demographic and other data on associated factors was collected using a pre-tested questionnaire. Capillary blood was taken from the fingertip of each child and hemoglobin was measured using Haemo-Cue digital photometer. All the necessary safety measures were taken during blood collection. Data analysis was made using SPSS version 21. Multivariable logistic regression analysis was used to assess the association of independent variables with outcome variables and to control the possible confounding factors.

RESULT

The overall prevalence of anaemia was 51.4%. Anaemia was common among young children as compared to older children. After controlling the effect of confounding and adjusting for age, gender and altitude, explanatory variables like low dietary diversity (AOR = 3.24; 95% CI [1.68-6.23]), food insecurity (AOR = 3.63; 95% CI [2.18-6.04]), stunting (AOR = 2.60; 95% CI [1.56-4.35]), underweight (AOR = 2.46; 95% CI [1.29-4.67]) and fever within 2 weeks (AOR = 2.49; 95% CI [1.29-4.81]) prior to the survey were significantly associated with anaemia. In conclusion, the overall prevalence of anaemia among children aged 6-59 months has remained a major public health importance in the study area. Integrated efforts need to be prioritized to improve the health as well as the nutritional status of children aged 6-59 months through appropriate feeding practices in infants and children.

PREVALÊNCIA E FATORES ASSOCIADOS À ANEMIA EM CRIANÇAS DE CRECHES: UMA ANÁLISE HIERARQUIZADA

RESUMO Objetivo: Determinar a prevalência e os fatores associados à anemia em crianças menores de cinco anos assistidas em creches públicas de um município no sudoeste da Bahia. Métodos: Estudo transversal com uma amostra de 677 crianças matriculadas nas creches públicas de Vitória da Conquista, Bahia. Para determinação da hemoglobina por meio de punção digital, utilizou-se hemoglobinômetro portátil, considerando-se valores de hemoglobina <11 g/dL como ponto de corte para o diagnóstico da anemia. Aplicou-se questionário aos pais ou responsáveis para coleta de informações socioeconômicas, características maternas e de saúde e nutrição da criança. Medidas antropométricas de peso e estatura foram utilizadas para avaliação do estado nutricional da criança. Análise de regressão de Poisson com variância robusta e seleção hierárquica das variáveis foi usada para verificar fatores associados com anemia. Resultados: A prevalência de anemia foi de 10,2% e houve mais prevalência nas crianças cujas moradias não apresentavam instalação sanitária (RP 3,36; IC95% 1,40-8,03); naquelas que não receberam aleitamento materno exclusivo (RP 1,80; IC95% 1,12-2,91); nas crianças com idade inferior a 36 meses (RP 1,85; IC95% 1,19-2,89) e com baixa estatura para a idade (RP 2,06; IC95% 1,10-3,85). Conclusões: A prevalência de anemia pode ser considerada um problema de Saúde Pública menor em crianças de creches populares nesse município. Crianças com condições sanitárias inadequadas, que não receberam leite materno exclusivo, bem como as em idades mais precoces e com déficit nutricional foram mais suscetíveis.

Structured Additive Quantile Regression for Assessing the Determinants of Childhood Anemia in Rwanda

Childhood anemia is among the most significant health problems faced by public health departments in developing countries. This study aims at assessing the determinants and possible spatial effects associated with childhood anemia in Rwanda. The 2014/2015 Rwanda Demographic and Health Survey (RDHS) data was used. The analysis was done using the structured spatial additive quantile regression model. The findings of this study revealed that the child’s age; the duration of breastfeeding; gender of the child; the nutritional status of the child (whether underweight and/or wasting); whether the child had a fever; had a cough in the two weeks prior to the survey or not; whether the child received vitamin A supplementation in the six weeks before the survey or not; the household wealth index; literacy of the mother; mother’s anemia status; mother’s age at the birth are all significant factors associated with childhood anemia in Rwanda. Furthermore, significant structured spatial location effects on childhood anemia was found.

How is dietary diversity related to haematological status of preschool children in Ghana?

Background: The role of dietary diversity on blood biomarkers may be significant, but the evidence is limited. Objective: This study assessed the association between dietary diversity and haematological status of children aged 6-59 months controlling for various known confounders. Design: The analysis in this study is based on the 2014 Ghana Demographic and Health survey data.The study involved 2,388 pre-school children aged 6-59 months who constituted the sub-sample for anaemia assessment. Results: The mean haemoglobin concentration (Hb) was 10.2 g/dl ± 1.50 (95 % CI: 10.1 to 10.3), and anaemia prevalence (Hb < 11 g/dl) among children aged 6-59 months was 66.8 % (CI: 63.7 to 69.8). In multivariable logistic regression analysis,continued breastfeeding [Adjusted odds ratio (AOR) = 1.9 (95% CI: 1.19-2.91], 12-23 months of age (AOR = 2.4 (95% CI: 1.40-3.98), having fever in last two weeks (AOR = 1.7 (95% CI: 1.20-2.45, birth interval ≤ 24 months (AOR = 1.9 (1.20-2.84), and poorest wealth quintile (AOR = 2.6 (95% CI: 1.48-4.48) were positively associated with anaemia. Conclusion: The current study showed that factors other than poor dietary diversity predicted anaemia among children aged 6-59 months in Ghana.

Anemia e níveis de hemoglobina em crianças indígenas Xavante, Brasil Central

RESUMO: Objetivo: Avaliar a prevalência de anemia, os níveis médios de hemoglobina e os principais fatores nutricionais, demográficos e socioeconômicos associados em crianças Xavante, em Mato Grosso, Brasil. Métodos: Realizou-se inquérito em duas comunidades indígenas Xavante na Terra Indígena Pimentel Barbosa visando avaliar todas as crianças com menos de dez anos. Foram coletados dados de concentração de hemoglobina, antropometria e aspectos socioeconômicos/demográficos por meio de avaliação clínica e questionário estruturado. Utilizaram-se os pontos de corte recomendados pela Organização Mundial da Saúde (OMS) para a classificação de anemia. Análises de regressão linear com hemoglobina como desfecho e regressão de Poisson com variância robusta com presença ou não de anemia como desfechos foram realizadas (intervalo de confiança de 95% -IC95%). Resultados: Os menores valores médios de hemoglobina ocorreram nas crianças com menos de dois anos, sem diferença significativa entre os sexos. A anemia atingiu 50,8% das crianças, prevalecendo aquelas com menos de dois anos 2 anos (77,8%). A idade associou-se inversamente à ocorrência de anemia (razão de prevalência - RP - ajustada = 0,60; IC95% 0,38 - 0,95) e os valores médios de hemoglobina aumentaram significativamente conforme o incremento da idade. Os maiores valores de escores z de estatura-para-idade reduziam em 1,8 vez a chance de ter anemia (RP ajustada = 0,59; IC95% 0,34 - 1,00). A presença de outra criança com anemia no domicílio aumentou em 52,9% a probabilidade de ocorrência de anemia (RP ajustada = 1,89; IC95% 1,16 - 3,09). Conclusão: Elevados níveis de anemia nas crianças Xavante sinalizam a disparidade entre esses indígenas e a população brasileira geral. Os resultados sugerem que a anemia é determinada por relações complexas e variáveis entre fatores socioeconômicos, sociodemográficos e biológicos.

Prevalence and factors associated with anaemia among children aged 6 to 59 months in Namutumba district, Uganda: a cross- sectional study

Background

Anaemia is one of the major causes of death among children under five years in Africa, with a prevalence of 64.6% among pre-school children. In 2014, we conducted a cross-sectional study in Namutumba district in East-central Uganda to determine the prevalence and factors associated with anaemia among children aged 6 to 59 months.

Methods

We conducted a household survey in 376 randomly selected households. One child aged 6 to 59 months was randomly sampled from each selected household. A structured questionnaire administered to an adult caregiver was used to collect household data. Blood was collected by finger or heel prick to estimate the haemoglobin level using a portable haemocue analyser. Anthropometric data including age, weight and height was collected for each child. A modified poisson regression model was used to determine the correlates of anaemia, prevalence ratios and their 95% confidence intervals (CI).

Results

The prevalence of anaemia was high (58.8%) and was highest among children aged 12 to 23 months (68.5%) and males (61.3%). About 27.7% children were stunted. Children aged 6–11 and 12–23 months were more likely to be anaemic (APR = 1.12; 95% CI: 1.05–1.19 and APR = 1.12; 95% CI: 1.00–1.24 respectively), Resident of Magada and Namutumba (urban areas) were less likely to be anaemic (APR = 0.89; 95% CI: 0.87–0.91and APR = 0.86; 95% CI: 0. 85–0.88 respectively). Children of caretakers of a big family size (seven or more children) and with any formal education were less likely to be anaemic (APR = 0.94; 95% CI: 0.89–0.99 and APR = 0.93; 95% CI: 0.87–0.99). Stunting (HAZ scores) was a predictor of anaemia (APR = 1.07; 95% CI: 1.02–1.12).

Conclusion

Anaemia is highly prevalent among children and there is need to invest in measures to prevent anaemia, especially among children in the rural areas.

Anemia and undernutrition among children aged 6-23 months in two agroecological zones of rural Ethiopia

BACKGROUND

Child malnutrition during the first 1,000 days, commencing at conception, can have lifetime consequences. This study assesses the prevalence of anemia and undernutrition among children aged 6-23 months in midland and lowland agroecological zones of rural Ethiopia.

METHODS

Cross-sectional data examining sociodemographic, anthropometry, hemoglobin levels, and meal frequency indicators were collected from 216 children aged 6-23 months and their mothers randomly selected from eight rural kebele (villages).

RESULTS

Of 216 children, 53.7% were anemic, and 39.8%, 26.9%, and 11.6% were stunted, underweight, and wasted, respectively. The prevalence of anemia was higher in the lowland agroecological zone (59.5%) than the midland (47.6%). Among those children who were stunted, underweight, and wasted, 63.5%, 66.7%, and 68.0% were anemic, respectively. Child anemia was significantly associated with the child not achieving minimum meal frequency, sickness during the last 2 weeks before the survey, stunting and low body mass index, and with maternal hemoglobin and handwashing behavior. The prevalence of stunting was higher in the lowland agroecological zone (42.3%) than the midland (36.2%). The predictors of stunting were age and sex of the child, not achieving MMF, maternal body mass index, and age. As maternal height increases, the length for age of the children increases (P=0.003).

CONCLUSION

The overall prevalence of anemia and undernutrition among children aged 6-23 months in these study areas is very high. The prevalence was higher in the lowland agro-ecological zone. Health information strategies focusing on both maternal and children nutrition could be sensible approaches to minimize stunting and anemia.

Prevalence and risk factors of anemia in children

OBJECTIVE

To identify the prevalence and factors associated with anemia in children attending Municipal Early Childhood Education Day Care Center (Centros Municipais de Educação Infantil [CMEI]) nurseries in Colombo-PR.

METHODS

Analytical, cross-sectional study with a representative sample of 334 children obtained by stratified cluster sampling, with random selection of 26 nurseries. Data collection was conducted through interviews with parents, assessment of iron intake by direct food weighing, and hemoglobin measurement using the finger-stick test. Bivariate association tests were performed followed by multiple logistic regression adjustment.

RESULTS

The prevalence of anemia was 34.7%. Factors associated with anemia were: maternal age younger than 28 years old (p=0.03), male children (p=0.02), children younger than 24 months (p=0.01), and children who did not consume iron food sources (meat+beans+dark green leafy vegetables) (p=0.02). There was no association between anemia and iron food intake in CMEI. However, iron intake was well below the recommended levels according to the National Education Development Fund resolution, higher prevalence of anemia was observed in children whose intake of iron, heme iron, and nonheme iron was below the median.

CONCLUSIONS

In terms of public health, the prevalence of anemia is characterized as a moderate problem in the studied population and demonstrates the need for coordination of interdisciplinary actions for its reduction in CMEI nurseries.

Factors associated with anemia in children under three years of age in Perú: analysis of the Encuesta Demográfica y de Salud Familiar, ENDES, 2007-2013

INTRODUCTION

Despite the reduction of poverty in Perú, the prevalence of anemia in the country remains high. 

OBJECTIVE

To identify socio-demographic, child and maternal-child care factors associated with anemia in children between 6 and 35 months in Perú. 

MATERIALS AND METHODS

We conducted an analytical and descriptive study that included registered data from the national survey on demography and family health, 2007-2013, on children between 6 and 35 months old, including the measurement of blood hemoglobin. Anemia was confirmed by hemoglobin-altitude corrected values below 11 mg/dl. We used multivariate logistic regression models to assess potential associated factors for anemia. 

RESULTS

Anemia prevalence was high (47.9%). Twelve factors were independently associated with anemia in children: Socio-demographic factors such as living outside Lima and Callao, in a low socioeconomic household, and having an adolescent mother with low education level; child-related factors as being male, younger than 24 months of age, and having fever in the previous two weeks, and maternal-child care factors such as lack of prenatal control in the first trimester of pregnancy, lack or short period of iron supplementation during pregnancy, house delivery, anemia detection at the moment of the survey, and lack of intestinal anti-parasite preventive treatment in the child. 

CONCLUSIONS

The analysis of survey data provided valuable information about factors associated with anemia in children between 6 and 35 months, which can be used to increase the coverage and effectiveness of maternal-child care practices.

Factors Associated with Anemia among Children Aged 6-23 Months Attending Growth Monitoring at Tsitsika Health Center, Wag-Himra Zone, Northeast Ethiopia

Background. Globally, about 47.4% of children under five are suffering from anemia. In Ethiopia, 60.9% of children under two years are suffering from anemia. Anemia during infancy and young childhood period is associated with poor health and impaired cognitive development, leading to reduced academic achievement and earnings potential in their adulthood life. However, there is scarcity of information showing the magnitude of iron deficiency anemia among young children in Ethiopia. Therefore, this study aimed at assessing prevalence and associated factors of iron deficiency anemia among children under two (6-23 months). Methods. Institution based cross-sectional study was carried out from March to May, 2014, at Tsitsika Health Center in Wag-Himra Zone, Northeast Ethiopia. Systematic random sampling technique was employed. Automated hemoglobin machine was used to determine the hemoglobin level. Socioeconomic and demographic data were collected by using a pretested and structured questionnaire. Binary logistic regression analysis was used to identify associated factors and odds ratio with 95% CI was computed to assess the strength of association. Results. Total of 347 children participated in this study. The overall prevalence of anemia was 66.6%. In multivariate logistic regression analysis, male sex (AOR = 3.1 (95% CI: 1.60-5.81)), 9-11 months of age (AOR = 9.6 (95% CI: 3.61-25.47)), poor dietary diversity (AOR = 3.2 (95% CI: 1.35-7.38)), stunting (AOR = 2.7 (95% CI: 1.20-6.05)), diarrhea (AOR = 4.9 (1.63-14.59)), no formal education (AOR = 2.6 (95% CI: 1.26-5.27)), early initiation of complementary food (AOR = 11.1 (95% CI: 4.08-30.31)), and lowest wealth quintile (AOR = 3.0 (95% CI: 1.01-8.88)) were significantly associated with anemia. Conclusion. The overall prevalence of anemia among children who aged 6-23 months has sever public health importance in the study area. Integrated efforts need to be prioritized to improve health as well as appropriate infant and young child feeding practice among children under.

Prevalence of iron-deficiency anemia in children aged less than 60 months: A population-based study from the state of Minas Gerais, Brazil

OBJECTIVE: To identify the prevalence of iron-deficiency anemia in children aged less than 60 months and the conditioning factors in Minas Gerais, Brazil. METHODS: This cross-sectional study conducted from February 2007 to July 2008 in Minas Gerais included a random sample of 725 male and female children aged less than 60 months. A household survey was administered to the children's parents or guardians to collect socioeconomic, demographic, food security, and the child's anthropometric data. The hemoglobin level was determined by a portable hemoglobinometer. Anemia was considered present when hemoglobin levels were below 11.0 g/dL. Statistical analyses estimated the prevalence of anemia and its association with socioeconomic, demographic, and food security-related variables. The model was adjusted by multivariate logistic regression. The significance level was set at 5% (p<0.05). RESULTS: The prevalence of anemia was 37.4%. The greatest prevalence occurred in the age group 6 to 24 months (43.0%). The associated variables were being female (PR=1.43; p<0.026); age (PR=1.53; p<0.024); and not frequenting a daycare center (PR=2.41; p<0.001). In the multivariate regression model, the variables being female and not frequenting a daycare center remained in the model. CONCLUSION: The present population-based study found that in Minas Gerais, one-third (37.5%) of the children aged less than 60 months have iron-deficiency anemia. The results show that not frequenting a daycare center and being female are risk factors for anemia.

Determinants of Anemia among Children Aged 6-59 Months Living in Kilte Awulaelo Woreda, Northern Ethiopia

Introduction. The aim of this study was to determine the prevalence of anemia and determinant factors among children aged 6-59 months living in Kilte Awulaelo Woreda, eastern zone. Method. A community based cross-sectional study was conducted during February 2013 among 6 tabias of Kilte Awulaelo Woreda, northern Ethiopia. A total of 568 children were selected by systematic random sampling method. Anthropometric data and blood sample were collected. Bivariate and multivariate logistic regression analyses were performed to identify factors related to anemia. Result. The mean hemoglobin level was 11.48 g/dl and about 37.3% of children were anemic. Children who were aged 6-23 months [AOR = 1.89: 95% CI (1.3, 2.8)], underweight [AOR = 2.05: 95% CI (1.3, 3.3)], having MUAC less than 12 cm [AOR = 3.35: 95% CI (2.1, 5.3)], and from households with annual income below 10,000 Ethiopian birr [AOR = 4.86: 95% CI (3.2, 7.3)] were more likely to become anemic. Conclusion. The prevalence of anemia among the children is found to be high. It was associated with annual household income, age, and nutritional status of the child. So, improving family income and increasing awareness of the mother/caregiver were important intervention.

Hemoglobin levels and prevalence of anemia in pregnant women assisted in primary health care services, before and after fortification of flour

We evaluated hemoglobin-Hb levels and prevalence of anemia in pregnant women before and after fortification of flour. It was developed a study to evaluate intervention, of the type before and after, with independent population samples. Study was conducted in primary health care services in Maringá, PR. We assessed 366 and 419 medical records, Before and After implementation of fortification. Pregnant women with Hb < 11g/dL were considered anemic. Data were submitted to multiple linear regression analysis. There was low prevalence of anemia affecting 12.3% and 9.4% pregnant women Before and After fortification (p > 0.05), but the Group After the fortification had higher Hb levels (p < 0.05). Hb levels associated with Group, gestational age, previous pregnancy number, employment and marital status (p < 0.05). Although the fortification of flour may have had role in increasing the mean hemoglobin, we need consider the contribution of other variables not investigated.

Tendência temporal e fatores determinantes da anemia em crianças de duas faixas etárias (6-23 e 24-59 meses) no Estado de Pernambuco, Brasil, 1997-2006

Para analisar a tendência temporal da anemia e de fatores associados em crianças de 6-23 e de 24-59 meses no Estado de Pernambuco, Brasil, foram utilizados os dados de dois inquéritos de saúde e nutrição. As amostras totalizaram 777 e 993 crianças de 6-59 meses, respectivamente na II PESN/1997 e na III PESN/2006. As variáveis exploratórias foram agrupadas em cinco níveis hierárquicos: fatores socioeconômicos; índice econômico e índice ambiental; fatores maternos; assistência à saúde e nutrição; morbidade e estado nutricional, analisadas pela regressão múltipla de Poisson. Entre os dois inquéritos, as prevalências de anemia apresentaram uma diminuição de 11,7% e 33,4%, respectivamente, para as crianças de 6-23 e de 24-59 meses. Na análise de tendência temporal apenas o tercil inferior do índice ambiental permaneceu como fator determinante da anemia para as crianças de 6-23 meses, e o tercil inferior do índice econômico se manteve estatisticamente significativo nas crianças de 24-59 meses. Conclui-se que houve diminuição mais significativa da anemia no grupo de 24-59 meses.
