Diarrhea and health inequity among Indigenous children in Brazil: results from the First National Survey of Indigenous People's Health and Nutrition

How, what, and why: housing, water & sanitation and wealth patterns in a cross-sectional study of the Guarani Birth Cohort, the first Indigenous birth cohort in Brazil

Background

Despite the importance of social determinants of health, studies on the effects of socioeconomic, sanitary, and housing conditions on Indigenous child health are scarce worldwide. This study aims to identify patterns in housing, water & sanitation, and wealth (HSW) in the first Indigenous birth cohort in Brazil-The Guarani Birth Cohort.

Methods

Cross-sectional study using baseline data from The Guarani Birth Cohort. We used Multiple Correspondence Analysis and Cluster Analysis. The clusters identified were ordered in increasing degrees of access to public policies and wealth, defining the patterns of HSW. Finally, we explored the association between the patterns and one of the health outcomes, hospitalization, in the birth cohort.

Findings

Three patterns were identified for housing and water & sanitation, and four for wealth status, resulting in 36 combinations of patterns (3 × 3 × 4). More than 62% of children in the cohort were found with the lowest wealth patterns. The distribution of children across patterns in one dimension was not fully determined by the other two dimensions. Statistically significant associations were found between precarious households and extreme poverty, and hospitalization.

Interpretation

We observed substantial heterogeneity in the distribution of children across the 36 combinations. These findings highlight that, should the dimensions of HSW be associated with health outcomes, as seen for hospitalization, they should be considered separately in multivariable models, in order to improve the estimation of their independent effects.

Food profile of Yanomami indigenous children aged 6 to 59 months from the Brazilian Amazon, according to the degree of food processing: a cross-sectional study

OBJECTIVE

The current study aimed to characterise the food profile of Yanomami indigenous children according to the degree of food processing and its associated factors.

DESIGN

This is a cross-sectional study with Yanomami indigenous children aged 6 to 59 months. Socio-demographic, maternal and infant data were collected through a standardised questionnaire. The food profile was obtained by using a list of thirty-four foods to verify the child's consumption of these foods on the day preceding the interview. Foods were classified according to the degree of processing based on the NOVA system (in natura or minimally processed, processed culinary ingredients, processed and ultra-processed). In natura and minimally processed foods were subdivided into 'regional' and 'urban' foods. Poisson regression analysis was applied to estimate the associated factors according to the 90 % CI.

SETTING

Three villages (Auaris, Maturacá and Ariabú) in the Yanomami indigenous territory, in the Brazilian Amazon.

PARTICIPANTS

In total, 251 Yanomami children aged 6 to 59 months were evaluated.

RESULTS

The prevalence of consumption of 'regional' and 'urban' in natura or minimally processed foods was 93 % and 56 %, respectively, and consumption of ultra-processed foods was 32 %. Ultra-processed food consumption was 11·6 times higher in children of Maturacá and 9·2 times higher in Ariabú when compared with the children of Auaris and 31 % lower in children who had mothers with shorter stature.

CONCLUSION

Despite the high frequency of consumption of in natura and minimally processed foods, the consumption of ultra-processed foods was substantial and was associated with demographic and maternal factors in Yanomani indigenous children under 5 years of age.

The impact of urbanisation on the cardiometabolic health of Indigenous Brazilian peoples: a systematic review and meta-analysis, and data from the Brazilian Health registry

BACKGROUND

Indigenous Brazilian peoples have faced an unparalleled increase in the rate of cardiovascular diseases following rapid nutritional transition to more urban diets. We aimed to conduct a systematic review and meta-analysis to evaluate the association between urbanisation (including data from Amazon rainforest deforestation) and cardiometabolic risk factors and outcomes.

METHODS

In this systematic review and meta-analysis, we searched Pubmed, Embase, Web of Science, and Scopus for articles published in any language between the year 1950 and March 10, 2022. Studies conducted in Indigenous Brazilian adults that evaluated metabolic health were included. Data for deforestation was obtained by the Amazon Deforestation Monitoring Project. Cardiovascular mortality was obtained from the Brazilian Health registry. Two independent reviewers evaluated studies for risk of bias, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. The main outcomes assessed were the prevalence of obesity and related cardiometabolic risk factors among Indigenous Brazilian peoples and its association with urbanisation. Summary data were extracted from published reports for the meta-analyses. We calculated pooled estimates of the prevalence of each cardiometabolic outcome by using a random-effects model (DerSimonian-Laird method). This study is registered with the International Prospective Register of Systematic Reviews, CRD42021285480.

FINDINGS

46 studies were identified, including a total of 20 574 adults from at least 33 Indigenous Brazilian ethnicities. Meta-analyses of the prevalence of obesity showed that there were higher rates of obesity (midwest region: 23% [95% CI 17-29]; and south region 23% [13-34]) and hypertension (south region: 30% [10-50]) in Indigenous peoples living in urban regions of Brazil, while the lowest rates of obesity (11% [95% CI 8-15]) and hypertension (1% [1-2]) were observed in those in the less urbanised (north) regions of Brazil. The prevalence of obesity was 3·5 times higher in participants living in urbanised Indigenous territories (28%) than in those living in lands with >80% native Amazon rainforest (8%). In meta-analyses that evaluated blood pressure level, there was no incremental change in blood pressure with ageing in Indigenous peoples who lived according to traditional lifestyle, in contrast to those living in urbanised regions. For Indigenous men with traditional lifestyles, systolic blood pressure changed from 109·8 mm Hg to 104·4 mm Hg between the youngest (<30 years) and the oldest (>60 years) age groups, and diastolic blood pressure changed from 69·8 mm Hg to 66·1 mm Hg. For Indigenous women with traditional lifestyles, systolic blood pressure was 100·0 mm Hg for the youngest age group with no changes for older age groups, and diastolic blood pressure was 62 mm Hg for the youngest age group with no changes for older age groups. For Indigenous men with urbanised lifestyles, systolic blood pressure changed from 117·3 mm Hg to 124·9 mm Hg between the youngest and the oldest age groups, and diastolic blood pressure changed from 72·7 mm Hg to 76·4 mm Hg. For Indigenous women with urbanised lifestyles, systolic blood pressure changed from 110·0 mm Hg to 116·0 mm Hg between the youngest and the oldest age groups, and diastolic blood pressure changed from 68·3 mm Hg to 74·0 mm Hg. For the years 1997 and 2019, the cardiovascular mortality rate in individuals living in the southeast region (the most urbanised) was 2·5 times greater than that observed in the north. Conversely, the incremental rise in cardiovascular mortality in the past two decades among Indigenous Brazilians living in the north or northeast (2·7 times increase) stands in stark contrast to the stable rates in those living in already urbanised regions.

INTERPRETATION

The macrosocial changes of Indigenous peoples' traditional ways of living consequent to urbanisation are associated with an increased prevalence of adverse cardiometabolic outcomes. These data highlight the urgent need for environmental policies to ensure the conservation of the natural ecosystem within Indigenous territories, as well as the development of socio-health policies to improve the cardiovascular health of Indigenous Brazilians peoples living in urban areas.

Prevalence of drinking or eating more than usual and associated factors during childhood diarrhea in East Africa: a multilevel analysis of recent demographic and health survey

Background

Diarrhea is the second most common cause of death in under-five children. Fluid and food replacement during diarrheal episodes have a paramount effect to avert morbidity and mortality. However, there is limited information about feeding practices. This study aimed to assess the prevalence of drinking or eating more and associated factors during diarrhea among under-five children in East Africa using demographic and health surveys (DHSs).

Methods

Secondary data analysis was done on DHSs 2008 to 2018 in 12 East African Countries. Total weighted samples of 20,559 mothers with their under-five children were included. Data cleaning, coding, and analysis were performed using Stata 16. Multilevel binary logistic regression were performed to identify factors associated with drinking or eating more during diarrheal episodes. Adjusted Odds Ratio (AOR) with a 95% CI, and p-value < 0.05 were used to declare statistical significance.

Results

Prevalence of drinking or eating more than usual during diarrhea disease in East Africa was 26.27%(95% CI: 25.68–26.88). Mothers age > 35 years (AOR: 1.14, 95% CI: (1.03, 1.26), mothers primary education (AOR: 1.17, 95% CI: 1.06,1.28), secondary education (AOR: 1.43,95% CI: 1.27,1.61), and higher education (AOR: 1.42,95% CI: 1.11,1.81), occupation of mothers (agriculture, AOR: 2.2, 95% CI: 1.3–3.6), sales and services, AOR = 1.20, CI:1.07,1.34), manual, AOR =1.28,95% CI: 1.11,1.44), children age 1–2 years (AOR =1.34,95% CI: 1.22,1.46) and 3–4 years (AOR =1.36,95% CI: 1.20,1.55), four and more antenatal visits (AOR: 1.14,95% CI: 1.03,1.27), rich wealth status (AOR:1.27,95% CI: 1.16,1.40), birth in health facility (AOR = 1.19, 95%CI: 1.10, 1.30) and visit health facility (AOR = 1.12, 95%CI: 1.03, 1.22) were associated with drinking or eating more.

Conclusion

The prevalence of drinking or eating more is low in East Africa. Maternal age, occupation, antenatal care visit, marital status, educational status, wealth status, place of delivery, visiting health facility, and child age were significantly associated with drinking or eating more during diarrheal episodes. Health policy and programs should focus on educating mothers, improving the household wealth status, encouraging women to contact health facilities for better feeding practices of children during diarrheal episodes.

Diarrhea and associated factors among under five children in sub-Saharan Africa: Evidence from demographic and health surveys of 34 sub-Saharan countries

Introduction

Diarrhea is responsible for the death of more than 90% of under-five children in low and lower-middle income countries. Regionally, South Asia and sub-Saharan Africa accounted for 88% of deaths with the same age group. Therefore, the aim of this study was to determine the prevalence and associated factors of diarrhea among children under-five years in sub-Saharan Africa.

Methods

The appended, most recent demographic and health survey datasets of 34 sub-Saharan African countries were used to determine the prevalence and associated factors of diarrhea among under-five children in the region. A total weighted sample of 330,866 under-five children were included in the study. Both bivariable and multivariable multilevel logistic regression were done to determine the associated factors of diarrhea among under five children in sub-Saharan Africa. The Odds Ratio (OR) with a 95% Confidence Interval (CI) was calculated for those potential factors included in the final model.

Result

The overall prevalence of diarrhea in this study was 15.3% (95% CI: 15.1–15.4). Those children of mothers aged 15–24 (AOR = 1.26; 95% CI: 1.23, 1.30) and 25–34 years (AOR = 1.15; 95%CI: 1.12, 1.18), those children of mothers with no education (AOR = 1.69; 95%CI: 1.57–1.82), primary education (AOR = 1.73; 95%CI: 1.61–1.86) and secondary education (AOR = 1.49; 95%CI: 1.38–1.59) had higher odds of having diarrhea. Those children from poorest (AOR = 1.14; 95%CI: 1.10, 1.19), poorer (AOR = 1.12; 95%CI: 1.08–1.17), middle (AOR = 1.06; 95%CI: 1.02, 1.10), and richer (AOR = 1.14; 95%CI: 1.04–1.12) households had higher chance of having diarrhea compared to their counterparts.

Conclusion

This study found that the prevalence of childhood diarrhea morbidity in sub-Saharan Africa was high. Maternal age, wealth index, maternal education, maternal occupation, age of child, time of initiation of breast feeding and time to get water source were significantly associated with diarrhea. Therefore, intervention through health education and health promotion for mothers/caretakers who are poor, less educated, and young should be designed to prevent diarrhea in the region.

[Nutritional status and factors associated with stunting in children under five years of age in maroon communities in Northeast Brazil]

Quilombolas, or members of maroon communities in Brazil, are part of the country's ethnic/racial minorities exposed to health inequities, reflecting a historical process of harsh socioeconomic disadvantages. The study aimed to assess nutritional status and factors associated with stunting in quilombola children under five years of age living in land-deeded quilombola communities in Northeast Brazil. The study used secondary data from the Survey on Food and Nutritional Security in Land-Deeded Quilombola Communities (2011). The target outcomes were stunting (height-for-age < -2z), excess weight (weight-for-height > 2z), and underweight (weight-for-age < -2z). Chi-square test was used to assess the significance of differences between prevalence rates. Multivariate analysis used a hierarchical conceptual model on stunting. Prevalence rates for excess weight and underweight were 2.8% and 6,1%, respectively. Stunting was diagnosed in 14.1% of the sample. The hierarchical model for stunting evidenced higher prevalence rates among children without access to primary healthcare (PR = 1.63; 95%CI: 1.11; 2.41) and safe water (PR = 2.09; 95%CI: 1.42; 3.08) and those with a history of low birthweight (PR = 2.19; 95%CI: 1.33; 3.61). The high prevalence of stunting showed that the quilombola' population in the Northeast experiences unfavorable health condition, reflecting lack of access to primary healthcare and precarious sanitation.

Educational interventions using a primer and motivational interviewing: randomized clinical trial

BACKGROUND

Many educational technologies have been used to promote the health of the population. Thus, the objective was to assess the effect of using an individual educational primer along with the Brief Motivational Interviewing (BMI) for increasing maternal self-efficacy for preventing childhood diarrhoea.

METHODS

Randomized clinical trial, conducted in Fortaleza/Ceará-Brazil, composed of 181 mothers and/or guardians of children under five years, who were randomized into three groups: experimental group A (EG A)-who read the primer, experimental group B (EG B)-application of the primer and BMI and the control group (CG). The participants' assessment was based on the Maternal Self-Efficacy Scale for Preventing Childhood Diarrhoea and the diarrhoea Investigation Form at the beginning of the intervention and then 30 and 60 days after the first contact with the participants.

RESULTS

There were 60 participants in EG A and CG and 61 in EG B. It was noted a greater incidence of participants with high self-efficacy in EG B after applying the technologies. All groups manifested diarrhoea among children after the interventions, although with a lower number in EG B, one-month post-intervention (P = 0.025).

CONCLUSIONS

The combined use of the primer and the BMI contributed significantly over time to increase maternal self-efficacy in preventing childhood diarrhoea and reduce cases of this disease.

Baixo peso ao nascer, prematuridade e restrição de crescimento intra-uterino: resultados dos dados de base da primeira coorte de nascimentos indígenas no Brasil (coorte de nascimentos Guarani)

ABSTRATO

FUNDO: O baixo peso ao nascer (BPN) continua sendo um importante problema de saúde global, associado a uma série de resultados adversos de saúde ao longo da vida. As evidências sugerem que o BPN é um determinante relevante de morbidade e mortalidade em grupos indígenas, que geralmente têm acesso limitado às políticas públicas de saúde e nutrição. O conhecimento da prevalência de BPN e de suas causas subjacentes pode contribuir com etapas essenciais para a prevenção de seus efeitos sobre a saúde. O estudo teve como objetivo estimar as prevalências de BPN, prematuridade e restrição de crescimento intra-uterino (RCIU) e investigar seus determinantes na primeira coorte de nascimentos indígenas no Brasil. MéTODOS: Este estudo transversal utilizou dados de linha de base coletados da primeira coorte de nascimentos indígenas no Brasil, a Coorte de Nascimentos Guarani. O Brasil é um dos países com maior diversidade étnica do mundo, com 305 povos indígenas e 274 línguas nativas. Os Guarani são uma das cinco maiores etnias, com aldeias localizadas principalmente na região sul. Todos os nascimentos únicos de 1º de junho de 2014 a 31 de maio de 2016 foram selecionados em 63 aldeias indígenas Guarani nas regiões Sul e Sudeste. Foi realizada regressão logística múltipla hierárquica.

RESULTADOS

As taxas de prevalência de BPN, prematuridade e RCIU foram 15,5, 15,6 e 5,7%, respectivamente. As chances de BPN foram menores em recém-nascidos de mães que vivem em casas de tijolo e argamassa (OR: 0,25; IC 95%: 0,07-0,84) e foram maiores em filhos de mães ≤20 anos de idade (OR: 2,4; IC 95%: 1,29-4,44) e com anemia crônica antes da gravidez (OR: 6,41; IC 95%: 1,70-24,16). A prematuridade foi estatisticamente associada ao tipo de fonte de energia para cozinhar (fogão a lenha - OR: 3,87; IC 95%: 1,71-8,78 e fogueiras - OR: 2,57; IC 95%: 1,31-5,01). RCIU foi associado à primiparidade (OR: 4,66; IC 95%: 1,68-12,95) e anemia materna crônica antes da gravidez (OR: 7,21; IC 95%: 1,29-40,38). CONCLUSõES: Idade materna, estado nutricional e paridade, condições de moradia e exposição à poluição interna foram associados com resultados perinatais na população indígena Guarani. Esses resultados indicam a necessidade de investir no acesso e melhoria da assistência pré-natal; também no fortalecimento do Subsistema de Saúde Indígena, e em ações intersetoriais para o desenvolvimento de políticas habitacionais e de saneamento e melhorias ambientais ajustadas às necessidades e conhecimentos dos povos indígenas.

Sanitation conditions of indigenous and nonindigenous households in Brazil according the 2000 and 2010 national censuses

This study compares the availability of basic sanitation infrastructure in indigenous and nonindigenous household located in urban and rural areas using data from the 2000 and 2010 Brazilian National Censuses. The analyses were based on descriptive statistics and modelling with multiple logistic regression. While there was an increase in the availability of basic sanitation in Brazilian households over the decade, indigenous households continued to have worse conditions in 2010. Sewage was the sanitation service with the lowest coverage in both censuses, and indigenous households had a lower rate of sewage services than nonindigenous households did. Logistic regression results confirmed the findings of the descriptive analyses, attesting to the fact that sanitation conditions are worse in indigenous households. In some areas, such as the urban North and Southeast and rural areas of the Central-West region, the gap in basic sanitation infrastructure between indigenous and nonindigenous households increased from 2000 to 2010. This study not only indicates the less-adequate sanitation conditions in indigenous households in Brazil but also attests to the persistence of major inequalities associated with race or color in the country.

Food Profiles of Indigenous Households in Brazil: Results of the First National Survey of Indigenous Peoples' Health and Nutrition

The objective of the present study was to characterize the food profiles in Indigenous households participating in the First National Survey of Indigenous People's Health and Nutrition in Brazil. Multiple correspondence analysis was used to estimate distances between regions and foods from three sources (local Indigenous production, purchased, and external donation), in addition to "not consumed." The combined distribution of the first two dimensions revealed three distinct profiles of food acquisition. Observed proximities between geopolitical regions and distinct modes of food acquisition speak to regional contrasts in food sovereignty among the Indigenous population that are closely linked to historical occupation and economic expansion in the country. Considering the concept of food sovereignty as involving rights to dietary autonomy, healthy diets, and resource management, our data suggest Brazil's North region is the closest of the four regions analyzed to these goals. Food sovereignty in the Northeast and South/Southeast regions is reduced due to greater monetarization and proximity to market economy resources. The advance of agribusiness in the Amazon has been a hallmark of the Brazilian government's current environmental policy, directly threatening the survival of Indigenous peoples living in that region.

Socioeconomic determinants of excess weight and obesity among Indigenous women: findings from the First National Survey of Indigenous People's Health and Nutrition in Brazil

Objective:

This article assesses the nutritional status of Indigenous women from 14 to 49 years of age in Brazil.

Design:

Sample size was calculated for each region considering a prevalence of 50 % for all disease outcomes, a relative error of 5 % and a CI of 95 %. In the initial data analysis, the prevalence of excess weight and obesity was calculated according to independent variables. Multivariate multilevel hierarchical analyses were conducted based on a theoretical model of two ranked blocks.

Setting:

The 2010 Indigenous population in Brazil was 896 000, with approximately 300 Indigenous ethnic groups, making Brazil one of the most ethnically diverse countries in the Americas and the world.

Participants:

Of the total target sample of 6722 women evaluated by the National Survey, thirty did not participate, 939 were not eligible for analyses due to pregnancy or unknown pregnancy status, and thirty-nine were excluded due to missing anthropometric data.

Results:

The evaluation of nutritional status was completed for 5714 non-pregnant women (99·3 % of eligible participants for this outcome). High prevalence rates were encountered for both excess weight (46·2 %) and obesity (15·8 %) among the sampled women. In the multivariate analyses, higher socioeconomic indicators, market-integrated living conditions and less reliance on local food production, as well as increased age and parity were associated with excess weight and obesity.

Conclusion:

Results point to distinct patterns of associations between socioeconomic indicators and the occurrence of excess weight and obesity among Indigenous women, which have potentially significant implications from a public policy perspective for Indigenous peoples in Brazil.

Epidemiological characteristics and strategies for the prevention of diarrheal disease in indigenous children: A scoping review

AIM

The aim of the present scoping review was to map the scientific evidence about diarrheal disease in indigenous children and the strategies that can be used to prevent it.

METHODS

The subject headings were indigenous population; child; diarrhea; dysentery; epidemiology; and prevention, primary; also the following keywords characteristic, epidemiologic study; and children. The databases consulted were Latin American and Caribbean Health Sciences Literature, MEDLINE via the US National Library of Medicine/National Institutes of Health, and Web of Science. Initially, 268 studies were identified, and after being screened using the eligibility criteria, six were selected. Finally, via reference tracking, five more were identified. The final sample was made up of eleven articles.

RESULTS

The results confirmed higher mortality rates due to diarrheal disease among indigenous children who are socially disadvantaged and living in poor hygienic and basic sanitation conditions. Among the primary prevention strategies are basic sanitation, health education better hygiene habits, animal control, breastfeeding, supplementing the diet with zinc, vitamins, and the rotavirus vaccine. The preventive strategies included the use of oral rehydration solutions, adequate nutrition, prescribed antimicrobials, and intravenous fluid replacement with glycaemic and electrolyte correction in severe cases.

CONCLUSION

In conclusion, public policies regarding the indigenous population and cross-cultural care should be strengthened. The present study confirmed that, at a global level, there is a lack of publications studying this issue.

The Xavante Longitudinal Health Study in Brazil: Objectives, design, and key results

OBJECTIVE

The Xavante Longitudinal Health Study was developed to permit granular tracking of contemporary health challenges faced by indigenous communities in Brazil, taking into consideration ongoing historical processes that may be associated with increases in child undernutrition, adult obesity, and cardiovascular disease risks.

METHODS

This was an open-cohort study with six semiannual data collection waves from 2009 to 2012. The study was undertaken in two Xavante villages, Pimentel Barbosa and Etênhiritipá, State of Mato Grosso, Central Brazil. No sampling technique was used. Data collection placed emphasis on growth and nutrition of children under five and nutrition status, blood pressure, and blood glucose levels of adolescents and adults.

RESULTS

Baseline data collection began in July/August 2009 with a population census (656 individuals). Between the first and final waves, the study population increased by 17%. At baseline, stunting and wasting was elevated for most age groups <10 years. Overweight, obesity, and increased risk of metabolic complications were expressive among individuals >17 years, disproportionately affecting females. Anemia was elevated in most age groups, especially among females. Mean systolic and diastolic blood pressure was moderate. The overall prevalence of high blood pressure was relatively low.

CONCLUSIONS

Our findings reveal marked health disparities relative to the Brazilian national population and a complex dietary health epidemiology involving the double burden of malnutrition, rapidly changing nutritional indicators, and elevated metabolic disease risk. The topically broad multidisciplinary focus permitted construction of the richest longitudinal data set of socio-epidemiological information for an indigenous population in Brazil.

[Basic sanitation and inequalities in color/race in urban households with under-five children, with a focus on the indigenous population]

This study aimed to analyze the presence of basic sanitation services in households with children under five years of age located in urban areas of Brazil, with a focus on indigenous children. This cross-sectional study was based on data from the 2010 Population Census. We calculated the rates of households with running water (public system), sewage disposal (public system or septic tanks), and garbage collection (directly or via public dumpsters). Multiple logistic regression (MLR) models were used to estimate associations between color/race and presence of sanitation services, based on odds ratios (OR). The study considered Brazil's urban metropolitan areas and stratified the results by major geographic region. Significance was set at 5%. The lowest frequencies were for sewage disposal, and all the rates were lower for indigenous people. MLR analyses included 29 comparisons (48.3%) in which households with indigenous children (compared to other color/race categories) were at a disadvantage, especially in the South of Brazil, where all comparisons were negative for indigenous households. Similar results appeared in metropolitan areas. The results thus suggest inequalities basic sanitation services based on color/race, where indigenous people are generally at a disadvantage, especially in the South of Brazil. Given the relationship between sanitation and health, as already demonstrated in the literature, these results can partly explain the low health levels in indigenous children in Brazil.

[Ethnic and racial inequalities in hospital admissions due to avoidable causes in under-five Brazilian children, 2009-2014]

There has been a global increase in hospital admissions for primary care-sensitive conditions (PCSCs) as an indicator of effectiveness in primary health care. This article analyzes ethnic and racial inequalities in cause-related hospitalizations in under-five children in Brazil as a whole and the country's five major geographic regions, with an emphasis on PCSCs and acute respiratory infections (ARIs). Using data from the Hospital Information Systems of the Brazilian Unified National Health System (SIH/SUS), 2009-2014, the authors calculated proportions, rates, and rate ratios for PCSCs, adjusted by sex and age after multiple imputation of missing data on color/race. The principal causes of hospitalization were respiratory tract infections (37.4%) and infectious and parasitic diseases (19.3%), and indigenous children were proportionally the most affected. Crude PCSC rates (per 1,000) were highest in indigenous children (97.3; 95%CI: 95.3-99.2), followed by brown or mixed-raced children (40.0; 95%CI: 39.8-40.1), while the lowest rates were in Asiandescendant children (14.8; 95%CI: 14.1-15.5). The highest adjusted rate ratios for PCSCs were seen among indigenous children compared to white children - 5.7 (95%CI: 3.9-8.4) for Brazil as a whole, reaching 5.9 (95%CI: 5.0-7.1) and 18.5 (95%CI: 16.5-20.7) in the North and Central, respectively, compared to white children. ARIs remained as important causes of pediatric hospitalizations in Brazil. Alarming ethnic and racial inequalities were observed in PCSCs, with indigenous children at a disadvantage. Improvements are needed in living conditions, sanitation, and subsistence, as well as guaranteed timely access to high-quality primary health care in the more vulnerable population groups, especially the indigenous peoples of the North and Central, in order to mitigate the health inequalities and meet the guidelines of the SUS and the Brazilian Constitution.

Is the effect of precipitation on acute gastrointestinal illness in southwestern Uganda different between Indigenous and non-Indigenous communities?

Acute gastrointestinal illness (AGI) is a global public health priority that often disproportionately effects Indigenous populations. While previous research examines the association between meteorological conditions and AGI, little is known about how socio-cultural factors may modify this relationship. This present study seeks to address this research gap by comparing AGI prevalence and determinants between an Indigenous and non-Indigenous population in Uganda. We estimate the 14-day self-reported prevalence of AGI among adults in an Indigenous Batwa population and their non-Indigenous neighbours using cross-sectional panel data collected over four periods spanning typically rainy and dry seasons (January 2013 to April 2014). The independent associations between Indigenous status, precipitation, and AGI are examined with multivariable multi-level logistic regression models, controlling for relative wealth status and clustering at the community level. Estimated prevalence of AGI among the Indigenous Batwa was greater than among the non-Indigenous Bakiga. Our models indicate that both Indigenous identity and decreased levels of precipitation in the weeks preceding the survey period were significantly associated with increased AGI, after adjusting for confounders. Multivariable models stratified by Indigenous identity suggest that Indigenous identity may not modify the association between precipitation and AGI in this context. Our results suggest that short-term changes in precipitation affect both Indigenous and non-Indigenous populations similarly, though from different baseline AGI prevalences, maintaining rather than exacerbating this socially patterned health disparity. In the context of climate change, these results may challenge the assumption that changing weather patterns will necessarily exacerbate existing socially patterned health disparities.

Factors Associated with Severe Dehydrating Diarrhoea in the Rural Western Cape, South Africa

BACKGROUND

Acute diarrhoea (AD) remains a leading cause of childhood death. We evaluated whether delayed healthcare seeking was associated with severe dehydration in rural South Africa.

METHODS

In a prospective cohort study of children with AD admitted to a secondary-level hospital, data were collected through structured caregiver interviews and hospital record review. The primary outcome was severe dehydration/death, and the primary determinant was delay >12 h between AD symptom onset and healthcare facility presentation.

RESULTS

Total 68% (71 of 104) of children experienced a delay, and 51% (54 of 104) had severe dehydration with no in-hospital deaths. There was no difference in children with (35 of 71) or without (19 of 33) delay for severe dehydration. Mothers of children with severe dehydration tended to be younger [median (interquartile range) 24 (21-28) vs. 27 (23-30) years, p = 0.07] and used less oral rehydration solution (63 vs. 80%, p = 0.08).

CONCLUSION

Delay of >12 h in seeking healthcare for AD was not associated with severe dehydration.

Condições de saneamento e desigualdades de cor/raça no Brasil urbano: uma análise com foco na população indígena com base no Censo Demográfico de 2010

RESUMO: Objetivo: Os objetivos deste estudo foram analisar e descrever a presença da infraestrutura de saneamento básico nas áreas urbanas do Brasil, contrastando os perfis dos domicílios indígenas com os de não indígenas. Métodos: Trata-se de um estudo transversal com base nos microdados do Censo 2010. As análises foram baseadas em estatísticas descritivas (prevalências) e na construção de modelos de regressão logística múltipla (ajustados por covariáveis socioeconômicas e demográficas). Estimaram-se as razões de chance para a associação entre as variáveis explicativas (covariáveis) e de desfecho (abastecimento de água, esgotamento sanitário, coleta de lixo e saneamento adequado). O nível de significância estatística estabelecido foi de 5%. Resultados: Entre os serviços analisados, o esgotamento sanitário mostrou-se o mais precário. Em relação à cor ou raça, os domicílios com responsáveis indígenas apresentaram as menores frequências de presença de infraestrutura sanitária no Brasil Urbano. Os resultados das regressões ajustadas mostraram que, em geral, os domicílios indígenas se encontram em desvantagem quando comparados aos de outras categorias de cor ou raça, especialmente quanto à presença do serviço de coleta de lixo. Essas desigualdades foram de maior magnitude nas regiões Sul e Centro-Oeste. Conclusão: As análises deste estudo não somente confirmam o perfil de precárias condições de infraestrutura de saneamento básico dos domicílios indígenas em área urbana, como também evidenciam a persistência de iniquidades associadas à cor ou raça no país.

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.

[The Aranãs in mid-Jequitinhonha: socioeconomic, demographic and sanitary aspects of a landless indigenous population]

The lack of epidemiological and environmental data on Brazilian indigenous populations is a challenge for the elaboration of public policy. This lack of data is more acute for "landless" indigenous groups. From this perspective, it was considered relevant to describe the Aranã, a landless indigenous group living in Minas Gerais, focusing on the demographic, socioeconomic and sanitary dimensions. A household survey was conducted. The data collected were analyzed and compared with those from other national ethnic groups. The results revealed similarities between these findings and those from the 2010 Census related to the native indigenous population, especially those not living on indigenous lands or reservations. Asymmetric results were identified within the households, mainly sanitary disparities, which suggested a relation with the location. This result indicates the need for priority intervention for the Aranã living in rural areas, bringing to light the age-old discussion about rural and urban disparities. In addition, we suggest that the Brazilian Institute of Geography and Statistics (IBGE), responsible for the 2010 census, should refine its assessment methods concerning landless indigenous groups.

Child Health in the Peruvian Amazon: Prevalence and Factors Associated with Referred Morbidity and Health Care Access in the City of Iñapari

Introduction. Children under 5 years of age are more susceptible to developing morbidities such as diarrhea, respiratory infections, anemia, and malnutrition. The objective of the study is to evaluate the prevalence of reported morbidities in this age group in the city of Iñapari (Peru) and the access to health services in this municipality. Methods. Data collection using interviews that assessed socioeconomic and demographic conditions, child morbidity, and access to health services was performed in 2011. Statistical analysis was performed using SPSS 13.0. Results. Regarding morbidities that occurred during lifetime, 39.8% reported previous anemia and intestinal parasite infection. About 53.7% of the children reported any type of morbidities in the last 15 days before interview, being most frequent respiratory symptoms (38.9%), diarrhea (23,4%), and fever (23,1%). Only 63.1% of those reporting recent morbidities sought health care. These morbidities were associated with precarious sanitation and lack of infrastructure, the presence of other comorbidities, and poor access to health services. Conclusion. The main referred morbidities in Amazonian Peruvian children were diarrhea, respiratory symptoms, anemia, and vomiting. Incentives and improvements in the health and sanitation conditions would be important measures to improve the quality of life of the Amazonian child population.

Comunidade quilombola na Região Nordeste do Brasil: saúde de mulheres e crianças antes e após sua certificação

Resumo Objetivos: caracterizar a situação de saúde de mulheres e crianças em uma comunidade quilombola no Nordeste do Brasil, antes e após sua certificação. Métodos: os dados procedem de dois inquéritos com metodologias similares, realizados em 2008 e 2009, no universo de mulheres e crianças residentes. As características socioeconômicas e de saúde das populações nos dois períodos foram comparadas pelo cálculo da Razão de Prevalência (RP), utilizando regressão de Poisson. Resultados: foram estudadas 143 mulheres e 194 crianças e 172 mulheres e 67 crianças nos anos de 2008 e 2012, respectivamente. As prevalências de excesso de peso (59,1% vs. 62,8%) e circunferência da cintura ≥80cm (59,5% vs. 57,4%) foram semelhantes entre os períodos (p>0,05). As características que apresentaram mudanças significantes (p<0,05) foram: renda familiar per capita >2 dólares/dia (23,2% vs. 67,4%; RP=2,90; IC95%: 2,11-4,01), prevalência de diarreia nas crianças (10,3% vs. 26,9%; RP=2,61; IC95%: 1,46-4,62), calendário vacinal atualizado (80,4% vs. 95,3%%; RP=1,18; IC95%: 1,08-1,30), frequência de suplementação de vitamina A (70,3% vs. 100,0%; RP=1,42; IC95%: 1,29-1,56), período de amamentação exclusiva ≥6 meses (8,7% vs. 44,6%; RP=5,13; IC95%: 2,95-8,92) e prevalência de anemia em crianças (41,6% vs. 20,0%; RP=0,48; IC95%: 0,27-0,87). Conclusões: ocorreram melhorias na situação de saúde, todavia ainda são necessários investimentos visando o incremento do padrão de saúde na comunidade.
