Multilevel Analysis of Determinants of Anemia Prevalence among Children Aged 6-59 Months in Ethiopia: Classical and Bayesian Approaches. Anemia 2018; 2018:3087354. [PMID: 29973986 PMCID: PMC6008921 DOI: 10.1155/2018/3087354] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2017] [Revised: 04/12/2018] [Accepted: 04/22/2018] [Indexed: 11/25/2022] Open
Abstract
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.

Mamabolo RL, Alberts M. Prevalence of anaemia and its associated factors in African children at one and three years residing in the Capricorn District of Limpopo Province, South Africa. Curationis 2014; 37:1160. [DOI: 10.4102/curationis.v37i1.1160] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Revised: 07/02/2014] [Accepted: 07/02/2014] [Indexed: 11/01/2022] Open
Abstract
Objective: The present study evaluated the prevalence of anaemia and its determinants in one- and three-year-old children from the Capricorn District of Limpopo Province, South Africa. Methods: A prospective cohort study conducted in rural villages in the Capricorn District of Limpopo Province, South Africa. At birth, a cohort of 219 children was followed until they were one and three years of age. Data collected included the children’s anthropometric measurements, blood for biochemical analysis (full blood count, ferritin, folate and vitamin B12) and socio-demographic status.Results: At one year, anaemia (Hb < 11 g/dL) was present in 52% of the children, decreasing to 22% by the third year. Iron deficiency (ferritin < 12 µg/mL) was common in these children (39% and 33% at one year and three years, respectively) particularly in the presence of anaemia. Folate and vitamin B12 deficiencies (< 5 ng/mL and < 145 pg/mL, respectively) were common at one year, with the children accumulating enough vitamin B12 by three years; however, folate deficiency levels remained fairly constant between the two time points.Conclusion: There was a high prevalence of anaemia in the study participants at one year and three years of age. Factors that increased the risk of anaemia at three years were: a mother with only a primary school education, anaemia at one year, male gender, overweight, and combined overweight and stunting. Protective factors against anaemia were having a younger mother who served as the main caregiver.

Abstract
BACKGROUND Due to the limited availability of data related to anemia in hospitalized children, this research was conducted to study the occurrence, morphological patterns, distribution in different age groups, sex, and severity of anemia among children aged 6 months-12 years. SETTING Inpatients in department of pediatrics at a multispecialty hospital, Bangalore. STUDY DESIGN Descriptive cross sectional study from Oct, 2011 to Sep, 2012. MATERIALS AND METHODS Ethical clearance was obtained from the ethical committee of the hospital as per 1964 Declaration of Helsinki. Unrestricted random sampling method was used to select the study group consisting of 882 children between the age of 6 months and 12 years. After obtaining the consent, data were obtained and statistically analyzed using statistical tools like mean, median, standard deviation, and Chi-square test. RESULTS Out of 882 children selected, 642 (72.79%) were anemic, out of which a majority of 629 (98%) children suffered from nonhemoglobinopathies and a meagre 13 (2%) suffered from hemoglobinopathies. Children in the age group of 6 months-1 year were most affected with nonhemoglobinopathies (33%). Moderate degree of anemia (hemoglobin = 7-9.9 g/dL) was the commonest grade of anemia (80%), while microcytic hypochromic anemia was commonest morphological type of anemia (48%). Among hemoglobinopathies, thalassemia major was the most common (69%, that is 9 out of 13 patients). CONCLUSION The occurrence of anemia among children aged between 6 months and 12 years is high and nonhemoglobinopathies predominate over the hemoglobinopathies.

[PMID: 20976516 PMCID: PMC3066395 DOI: 10.1007/s00038-010-0201-0] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2010] [Revised: 07/22/2010] [Accepted: 09/20/2010] [Indexed: 11/29/2022] Open
Abstract
Objectives To review the published literature examining the impacts of the Aral Sea disaster on children’s health. Methods A systematic review of the English language literature. Results The literature search uncovered 26 peer-reviewed articles and four major reports published between 1994 and 2008. Anemia, diarrheal diseases, and high body burdens of toxic contaminants were identified as being among the significant health problems for children. These problems are associated either directly with the environmental disaster or indirectly via the deterioration of the region’s economy and social and health care services. While links between persistent organic pollutant exposures and body burdens are clear, health impacts remain poorly understood. No clear evidence for the link between dust exposure and respiratory function was identified. Conclusion While important questions about the nature of the child health and environment relationships remain to be answered, the literature unequivocally illustrates the seriousness of the public health tragedy and provides sufficient evidence to justify immediate action. Regrettably, international awareness of the crisis continues to be poor, and the level of action addressing the situation is wholly inadequate.

[PMID: 16809889 DOI: 10.1159/000092347] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2004] [Accepted: 08/16/2005] [Indexed: 11/19/2022]
Abstract
The prevalence rates of hypoferritinemia (IDec/one abnormal indicator), iron deficiency (IDef/two abnormal indicators) and iron deficiency anemia (IDA) in children who were referred to the outpatient clinics of the Department of Pediatrics for the first time within 1 month were investigated. Exclusion criteria were iron therapy before and during the study period and a history of chronic illness. Acute-phase reactants, such as erythrocyte sedimentation rate and C-reactive protein levels, were measured in all cases indicative of infectious diseases. Blood samples were obtained from each study patient admitted to the outpatient clinics during the study period. The hospital charts were later further evaluated, and samples of patients with any current illness known to interact with the iron status of the patient were discarded, and patients were contacted to supply new samples about 1 month after treatment of the infection. Thus, in patients with indications of an infection, samples obtained 1 month after treatment were assessed. The children (n = 557) were divided into four age groups: those aged 4 months to 2 years (group I), 2-6 years (group II), 7-12 years (group III) and 12-18 years (group IV). Children with a decrease in serum ferritin levels without anemia (IDec), and those with lower ferritin, transferrin saturation (TS) and serum iron (SI) concentration (IDef) were evaluated. IDA was diagnosed if hemoglobin (Hb) concentrations were lower than those adjusted for age, ferritin <12 ng/ml and TS <or=16% and if SI was decreased. IDec, IDef and IDA were detected in 26, 11.1 and 12.7% of the patients, respectively. Only 50.1% of the patients visiting the outpatient clinics were found to be normal. The rates of IDec (28.9%), IDef (21.9%) and IDA (26.2%) were highest in group I. IDec had the highest percentages in all groups. In group I, the rates of IDec, IDef, and IDA were 37.2, 66.1 and 69%, respectively. SI concentration was abnormal in 77.1% of the cases in group I (4 months to 2 years of age). Half of the patients referred to the outpatient clinics were suffering from abnormalities related to lower SI concentrations. Close monitoring and treatment of iron deficiency is advised especially in early childhood.

Abstract
Iron-deficiency anemia (IDA) in refugees is reported to be among the major medical problems worldwide. Because food rations are typically inadequate in iron, long-term reliance is a key predictor of anemia among displaced people. Comprehensive nutritional assessments of refugee children from Burma have not previously been completed. Refugee children aged 6-59 mo were studied to determine 1) the prevalences of anemia, iron deficiency (ID) and IDA and 2) the factors associated with anemia and ID. Cluster sampling in three camps and convenience sampling in two additional camps were used. Hemoglobin (Hb) levels were measured and micro mol zinc protoporphyrin/mol heme were determined in 975 children. Logistic regression analyses (95% CI) determined predictors of anemia and ID. The prevalences of IDA, anemia and ID in these refugee children were 64.9, 72.0 and 85.4%, respectively. Predictors of anemia included young age (P < 0.001), food ration lasting <1 mo (P = 0.001), daily consumption of dietary iron inhibitors (P < 0.05), weight-for-height Z-score of <-2 (P < 0.05), male gender (P < 0.05) and uneducated father (P < 0.001). Predictors of ID were young age (P < 0.001) and recently reported illness (P < 0.05). Laboratory tests confirmed that anemia and ID are major health problems among these refugee children and that ID is the leading cause of anemia. A comprehensive nutrition and public health-focused approach to combating anemia and ID is essential. Following the presentation of results to policy makers, the improvement of the micronutrient content of rations has been initiated.

Abstract
This study examined the effect of psychosocial factors and environmental perceptions on self-rated health in the environmentally devastated Aral Sea area of Karakalpakstan. Self-rated health was assessed using a questionnaire on 881 randomly selected individuals from three communities. Communities were chosen based on relative differences with regards to economic and ethnic characteristics, and distance from the sea coast. Consistent with mortality rates in the area, the prevalence of 'poor' self-rated health was high. Factors negatively associated with self-rated health include psychosocial impacts and reported environmental concern, as well as community of residence and age. These results demonstrate that the population has a poor perception of their own health, a significant finding given that self-rated health is a strong predictor of morbidity and mortality. It is also clear that psychosocial health is strongly associated with health perceptions. Thus, to improve the overall health of this population, health remediation measures must address physical as well as psychosocial health problems.

Abstract
The people of Karakalpakstan, along with those of the entire Aral Sea region, are facing a multitude of health problems corresponding to the drying of the Aral Sea and accompanying ecological consequences. In case studies of other environmental disasters, research has shown that environmental exposures may impact not only the physiological but also the psychosocial health of individuals. This research aims to determine the contribution of the environmental disaster to the psychosocial health of people living in Karakalpakstan, a semi-autonomous Republic in Uzbekistan. An interview survey was carried out by Médecins Sans Frontières, with the assistance of the McMaster Institute of Environment and Health, local Universities and local health care workers, on a random sample of 1118 individuals aged 18 years and older in three communities in Karakalpakstan in May/June 1999. The communities were chosen according to distance from the former seashore, urban/rural characteristics and ethnic composition. The survey included questions about perceived general health, the General Health Questionnaire, the somatic symptom checklist of the Symptom Check List-90, questions about perceptions of the environmental disaster, social support as well as socio-demographic and socio-economic characteristics. Findings show that 41% of all respondents reported environmental concern while 48% reported levels of somatic symptoms (SCL-90) associated with emotional distress, above the normalized cut-point. Significant differences in levels of emotional distress were reported between men and women as well as between ethnic groups. Environmental problems are commonly perceived to be the cause of somatic symptoms and are significantly related to self-rated health status.

Abstract
A study on the pattern of anemia and its relation to nutritional status and dietary habits was conducted among 3633 pre-school children of 108 selected anganwadi centers in rural areas of Kerala State during the period 1996 to 1998. Children were invited with their parent or guardian. Capillary blood was collected from each child and hemoglobin was estimated by cyanomethemoglobin method. Weight and height of children were taken for assessing their nutritional status. The information regarding their age, sex, clinical condition and dietary habits was collected in a performa through an interview. Chi-square test was used to assess the relationship of anemia to sex, dietary habits, and nutritional status. For multivariate analysis logistic regression model was employed. The prevalence of anemia was 11.4%. The percentage of anemic children among male and female children was 10.25 and 12.55 respectively and statistical analysis showed that female children were more susceptible to anemia. Normal nutritional status was seen among 46.7% of the children. When 187 (11.78%) of the mild undernourished children were anemic, the percentage anemic among the moderate undernourished children was 57 (16.37%). Moderate under nutrition and anemia showed a significant association. Anemia was reported among both vegetarians and non-vegetarians. Among 927 vegetarians, 86 (9.27%) were anemic and among 2,706 non-vegetarians, 328 (12.1%) were anemic. Dietary survey revealed that, consumption of iron sources, whether haem or non-haem, was below the recommended level. Undernutrition can be attributed as the major reason for nutritional anemia. Changes in eating behaviour could have potentially affected the iron bio-availability.
