الوصف: ABSTRACT OBJECTIVE: To describe the prevalence pattern of anemia among Indigenous children in Latin America. METHODS: PRISMA guidelines were followed. Records were identified from the databases PubMed, Google Scholar, and Lilacs by two independent researchers between May and June 2021. Studies were included if the following criteria were met: a) studied Indigenous people b) was about children (from 0 to 12 years old); c) reported a prevalence estimate of anemia; d) had been conducted in any of the countries of Latin America; e) was published either in English, Portuguese, or Spanish; f) is a peer-reviewed article; and g) was published at any date. RESULTS: Out of 2,401 unique records retrieved, 42 articles met the inclusion criteria. A total of 39 different Indigenous communities were analyzed in the articles, and in 21 of them (54.0%) child anemia was a severe public health problem (prevalence ≥ 40%). Those communities were the Aymara (Bolivia); Aruak, Guaraní, Kamaiurá, Karapotó, Karibe, Kaxinanuá, Ma-cro-Jê, Suruí, Terena, Xavante (Brazil); Cabécar (Costa Rica), Achuar, Aguaruna, Awajún, Urarina, Yomybato (Peru); Piaroa and Yucpa (Venezuela); and Quechua (Peru and Bolivia). Children below two years had the highest prevalence of anemia (between 16.2% and 86.1%). Among Indigenous people, risk factors for anemia include nutrition, poor living conditions, access to health services, racism, and discrimination. Bolivia and Guatemala are scarcely studied, despite having the highest proportion of Indigenous communities in Latin America. CONCLUSIONS: Anemia constitutes a poorly documented public health problem among Indigenous children in 21 Indigenous communities in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Mexico, and Peru. In all Indigenous communities included in this study child anemia was an issue, especially in younger children.

الوصف: Abstract Background The global burden of anemia is large especially in sub-Saharan Africa, where HIV is common and lifestyles are changing rapidly with urbanization. The effects of these changes are unknown. Studies of anemia usually focus on pregnant women or children, among whom the burden is greatest. We describe prevalence and risk factors for anemia among rural and urban men and women of all ages in Malawi. Methods We analyzed data from a population-wide cross-sectional survey of adults conducted in two sites, Karonga (rural) and Lilongwe (urban), commencing in May 2013. We used multinomial logistic regression models, stratified by sex to identify risk factors for mild and moderate-to-severe anemia. Results Anemia prevalence was assessed among 8,926 men (age range 18–100 years) and 14,978 women (age range: 18–103 years). Weighted prevalence levels for all, mild, and moderate-to-severe anemia were 8.2, 6.7 and 1.2% in rural men; 19.4, 12.0 and 7.4% in rural women; 5.9, 5.1 and 0.8% in urban men; and 23.4, 13.6 and 10.1% in urban women. Among women, the odds of anemia were higher among urban residents and those with higher socioeconomic status. Increasing age was associated with higher anemia prevalence in men. Among both men and women, HIV infection was a consistent risk factor for severity of anemia, though its relative effect was stronger on moderate-to-severe anemia. Conclusions The drivers of anemia in this population are complex, include both socioeconomic and biological factors and are affecting men and women differently. The associations with urban lifestyle and HIV indicate opportunities for targeted intervention.

الوصف: Background Severe anaemia (haemoglobin Methods Secondary analyses of the trial examined 3894 children from Uganda and Malawi surviving a hospital episode of severe anaemia. Predictors of all-cause readmission within 180 days of discharge were identified using multivariable regression with death as a competing risk. Groups of children with similar characteristics were identified using hierarchical clustering. Results Of the 3894 survivors 682 (18%) were readmitted; 403 (10%) had ≥2 re-admissions over 180 days. Three main causes of readmission were identified: severe anaemia (n = 456), malaria (n = 252) and haemoglobinuria/dark urine syndrome (n = 165). Overall, factors increasing risk of readmission included HIV-infection (hazard ratio 2.48 (95% CI 1.63–3.78), p p p = 0.005); and missing ≥1 trial medication dose (proxy for care quality) (1.43 (1.21–1.69), p p = 0.04). Malaria (among children with no prior history of transfusion) (0.60(0.47–0.76), p p p = 0.001) also decreased risk of readmission. For anaemia re-admissions, gross splenomegaly and enlarged spleen increased risk by 1.73(1.23–2.44) and 1.46(1.18–1.82) respectively compared to no splenomegaly. Clustering identified four groups of children with readmission rates from 14 to 20%. The cluster with the highest readmission rate was characterised by very low haemoglobin (mean 3.6 g/dL). Sickle Cell Disease (SCD) predominated in two clusters associated with chronic repeated admissions or severe, acute presentations in largely undiagnosed SCD. The final cluster had high rates of malaria (78%), severity signs and very low platelet count, consistent with acute severe malaria. Conclusions Younger age, HIV infection and history of previous hospital admissions predicted increased risk of readmission. However, no obvious clinical factors for intervention were identified. As missing medication doses was highly predictive, attention to care related factors may be important. Trial registration ISRCTN ISRCTN84086586.

الوصف: OBJECTIVE To assess the prevalence of anemia and associated factors in older adults. METHODS The prevalence and factors associated with anemia in older adults were studied on the basis of the results of the Saúde, Bem-Estar e Envelhecimento (SABE – Health, Welfare and Aging) study. A group of 1,256 individuals were interviewed during the third wave of the SABE study performed in Sao Paulo, SP, in 2010. The study included 60.4% females; the mean age of the participants was 70.4 years, and their average education was 5.3 years. The dependent variable was the presence of anemia (hemoglobin levels: 12 g/dL in women and 13 g/dL in men). Descriptive analysis and hierarchical logistic regression were performed. The independent variables were as follows: a) demographics: gender, age, and education and b) clinical characteristics: self-reported chronic diseases, presence of cognitive decline and depression symptoms, and body mass index. RESULTS The prevalence of anemia was 7.7% and was found to be higher in oldest adults. There was no difference between genders, although the hemoglobin distribution curve in women showed a displacement toward lower values in comparison with the distribution curve in men. Advanced age (OR = 1.07; 95%CI 0.57;1.64; p < 0.001), presence of diabetes (OR = 2.30; 95%CI 1.33;4.00; p = 0.003), cancer (OR = 2.72; 95%CI 1.2;6.11; p = 0.016), and presence of depression symptoms (OR = 1.75; 95%CI 1.06;2.88; p = 0.028) remained significant even after multiple analyses. CONCLUSIONS The prevalence of anemia in older adults was 7.7% and was mainly associated with advanced age and presence of chronic diseases. Thus, anemia can be an important marker in the investigation of health in older adults because it can be easily diagnosed and markedly affects the quality of life of older adults.

الوصف: OBJETIVO: Estimar a prevalência da anemia em crianças, sua tendência temporal e identificar fatores associados. MÉTODOS: Estudo de corte transversal, de base populacional, envolvendo 1.108 crianças, com idade entre seis e 59 meses, de ambos os sexos, do Estado da Paraíba, em 2007. A hemoglobina foi analisada em sangue venoso com contador automático. Foram considerados para anemia valores < 11,0 g/dL, forma leve 9-11g/dL, moderada 7-9 g/dL e grave < 7,0 g/dL. As condições socioeconômicas e demográficas das crianças foram obtidas por meio de questionário aos pais ou responsáveis. As proporções foram comparadas pelo teste do qui-quadrado de Pearson, e a associação entre as concentrações de hemoglobina e potenciais fatores de riscos foi testada pelo modelo de regressão de Poisson. A tendência temporal da anemia foi avaliada pelo incremento/redução na prevalência de anemia nos anos de 1982, 1992 e 2007. RESULTADOS: A prevalência de anemia foi de 36,5% (IC95% 33,7;39,3). Observa-se que 1,3% (IC95% 0,7;1,8) foi na forma grave, 11,1% (IC95% 9,4;13,5) na forma moderada e 87,6% (IC95% 79,1;91,2) na forma leve. Houve um incremento de 88,5% nos casos de anemia no período entre 1982 e1992 e uma estabilização na prevalência entre 1992 e 2007. A análise ajustada no modelo de Poisson mostrou maior suscetibilidade à anemia nas crianças de seis a 24 meses de idade, naquelas amamentadas por seis meses ou mais, que co-habitavam com mais de quatro pessoas no mesmo domicílio e moravam em casas com menos de cinco cômodos. CONCLUSÕES: A alta prevalência de anemia mostra que continua sendo um importante problema de saúde pública no Estado da Paraíba. Apesar da estabilização na prevalência entre 1992 e 2007, a anemia apresenta-se em elevado patamar, o que impõe medidas mais efetivas de prevenção e controle.OBJETIVO: Estimar la prevalencia de la anemia en niños, su tendencia temporal e identificar factores asociados.

Se consideraron para anemia valores OBJECTIVE: To estimate the magnitude of the anemia, to analyze the time trends and investigate the factors associated with this disturbance in children in the state of Paraíba, Brazil. METHODS: A cross-sectional survey, of population-based, with 1108 children, aged 6 to 59 months, both sexes in the state of Paraíba. Hemoglobin (Hb) in venous blood was analyzed with an automatic counter. The social-economic and demographic characteristics of children were obtained by questionnaire. Proportions were compared by Pearson's chi-squared test, and the association between hemoglobin concentrations and potential risk factors was tested by regression model Poisson. The time trend of anemia was assessed by the increase/decreased in the prevalence of anemia, using as comparison the prevalence observed in the years 1982, 1992 and 2007. RESULTS: The prevalence of anemia (Hb < 11.0 g/dl) in the state of Paraíba was 36.5% (CI95% 33.7 to 39.3). It was observed that 1.3% (CI95% 0.7 to 1.8) were in severe form (Hb

الوصف: "Iron deficiency is recognized throughout the world as a major public health concern, particularly in developing countries. Among its functional consequences are reduced resistance to infection, increased morbidity and mortality, impaired learning and behavior, lower physical capacity and productivity, and increased susceptibility to cold. It is not, however, only the domain of nutritional biologists and of medical researchers. The skeletal evidence from archaeological excavations suggests that iron deficiency anemia was equally common in the past, thus making it of interest to paleoanthropology and paleopathology. That entire tribes present chronic iron deficiency makes it a phenomenon of interest to current anthropology as well." "Traditionally this condition has been attributed in large part to dietary factors, but there is evidence in both the skeletal record and in hematological analysis of living populations that acquired iron deficiency can derive from factors other than diet. Recognizing that the subject lends itself to multiple perspectives that can more comprehensively address the multi-factorial nature of iron deficiency anemia, the editors have assembled the present volume, the first of its kind. Among the contributors are leading researchers in a number of disciplines: ethnography, archaeology, physical anthropology, microbiology, and medicine. Together, these contributions serve to challenge the conventional views of the relationship between health, disease, and iron; of the symptomatic role of low iron levels; of cultural imperatives related to diet, such as daily meat intake; and of prescribed iron fortification." "This collection will stimulate controversy and further research within medical anthropology, and among public health officials, epidemiologists, hematologists, and medical sociologists."--Jacket.

الوصف: OBJECTIVE: To determine the most effective method for analysing haemoglobin concentrations in large surveys in remote areas, and to compare two methods (indirect cyanmethaemoglobin and HemoCue) with the conventional method (direct cyanmethaemoglobin). METHODS: Samples of venous and capillary blood from 121 mothers in Indonesia were compared using all three methods. FINDINGS: When the indirect cyanmethaemoglobin method was used the prevalence of anaemia was 31-38%. When the direct cyanmethaemoglobin or HemoCue method was used the prevalence was 14-18%. Indirect measurement of cyanmethaemoglobin had the highest coefficient of variation and the largest standard deviation of the difference between the first and second assessment of the same blood sample (10-12 g/l indirect measurement vs 4 g/l direct measurement). In comparison with direct cyanmethaemoglobin measurement of venous blood, HemoCue had the highest sensitivity (82.4%) and specificity (94.2%) when used for venous blood. CONCLUSIONS: Where field conditions and local resources allow it, haemoglobin concentration should be assessed with the direct cyanmethaemoglobin method, the gold standard. However, the HemoCue method can be used for surveys involving different laboratories or which are conducted in relatively remote areas. In very hot and humid climates, HemoCue microcuvettes should be discarded if not used within a few days of opening the container containing the cuvettes.

الوصف: Background Anaemia is a global health problem and women in reproductive age (WRA) are amongst the most affected population. Its consequences include low birth weight and maternal mortality. This study aimed to assess the prevalence of anaemia and to identify its determinants in Sudanese women in reproductive age. Methods A population-based cross-sectional study was conducted in Sudan in 2016. A multi-stage stratified cluster sampling design was executed with consideration of rural population, urban population, and internally displaced persons/refugees camps residents. All women in reproductive age (15–49 years), classified by pregnancy status, in the targeted households were surveyed and personal characteristic data were collected. Their haemoglobin level and malaria infection (using rapid diagnostic test, RDT) were assessed. The World Health Organization (WHO) haemoglobin level cut-off for defining anaemia and severe anaemia in pregnant and non-pregnant women was used. Logistic regression analyses were performed. Results A total of 4271 women (WRA) of which 421 (9.9%) pregnant women (PW) were included in the study. The overall anaemia prevalence in WRA was 35.6%. It was 36.0 and 35.5% in PW and non-pregnant women (NPW), respectively. The average haemoglobin level was found to be 113.9 g/L (SD 16.3) and 123.2 g/L (SD 15.7) for PW and NPW respectively. Severe anaemia prevalence was 1.2% in each group. In the logistic regression model, anaemia was associated with malaria infection in PW (aOR 4.100, 95%CI 1.523–11.039, p = 0.003), NPW (aOR 2.776, 95%CI 1.889–4.080, p p p = 0.007) and in WRA was being in the poorest economic class (aOR 1.436, 95%CI 1.065–1.936, p = 0.018). Conclusions Anaemia is a public health problem in Sudan. The study supported the association between malaria infection and anaemia, but not with low and moderate malaria transmission areas. Resources need to be allocated for all anaemic populations with special attention for the populations in most need and interventions need to be implemented based on local variations. Malaria control interventions, specifically case management, may have a major impact in reducing anaemia prevalence in low to moderate malaria transmission areas.
