Healthcare access and health beliefs of the indigenous peoples in remote Amazonian Peru

Capacity of community health centers to treat snakebite envenoming in indigenous territories of the Brazilian Amazon

INTRODUCTION

The deaths from and morbidities associated with snakebites - amputations, loss of function in the limb, visible scarring or tissue damage - have a vast economic, social, and psychological impact on indigenous communities in the Brazilian Amazon, especially children, and represent a real and pressing health crisis in this population. Snakebite clinical and research experts have therefore proposed expanding antivenom access from only hospitals to include the community health centers (CHC) located near and within indigenous communities. However, there are no studies examining the capacity of CHCs to store, administer, and manage antivenom treatment. In response to this gap, the research team calling for antivenom decentralization developed and validated an expert-based checklist outlining the minimum requirements for a CHC to provide antivenom.

METHODS

The objective of this study was thus to survey a sample of CHCs in indigenous territories and evaluate their capacity to provide antivenom treatment according to this accredited checklist. The checklist was administered to nurses and doctors from 16 CHCs, two per indigenous district in Amazonas/Roraima states.

RESULTS

Our results can be conceptualized into three central findings: 1) most CHCs have the capacity to provide antivenom treatment, 2) challenges to capacity are human resources and specialized items, and 3) antivenom decentralization is feasible and appropriate in indigenous communities.

CONCLUSION

Decentralization would provide culturally and contextually appropriate care accessibility to a historically marginalized and underserved population of the Brazilian Amazon. Future studies should examine optimal resource allocation in indigenous territories and develop an implementation strategy in partnership with indigenous leaders. Beyond the indigenous population, the checklist utilized could be applied to community health centers treating the general population and/or adapted to other low-resource settings.

Discourse of the collective subject of river dwellers in the Brazilian Amazon regarding the transmission of knowledge about medicinal plants

This paper investigates the perception of river dwellers in the Brazilian Amazon region about factors that influence the transmission of Traditional Ecological Knowledge (TEK) regarding medicinal plants. Semi-structured interviews were conducted with 43 residents of Vila Franca community (Pará, Brazil). The data were analyzed using the methodological strategy of the Discourse of the Collective Subject. The determining factors in the transmission of TEK were found to be: illness, family coexistence, and necessity, which were represented in the discourses as the most important factors for the acquisition of TEK. In the community context, the locally developed Natural Remedies Project, the beneficial effects of natural remedies, and the lack of resources to purchase allopathic medicines were cited as collaborative factors in the maintenance of TEK. Finally, the most significant determining factors in the decrease or loss of transmission of TEK found in the interviews were: lack of commitment, disbelief, and the valorization of allopathic medicines. A complex network of interactions between the villagers and their natural environment affects the transmission of TEK about medicinal plants. However, we found that the perpetuation of TEK is being threatened by various socio-economic and cultural factors.

Looking at maternal health of Asháninka communities from the conceptual framework of the accessibility of care

BACKGROUND

Peru is one of the 20 countries that has significantly reduced maternal mortality before the pandemic due to implementing policies to strengthen maternal health care, mainly in rural areas with greater poverty. However, the implementation of these policies has been different across the territory; such is the case of the indigenous communities of the Peruvian Amazon that are characterized by the inaccessibility of their territory and continue to face severe problems in accessing maternity care in health services.

OBJECTIVE

Analyze the main dimensions of accessibility for maternal care in public health services for women of the Asháninka community of Peru between 2016 and 2018.

METHODS

Qualitative research was carried out in the Asháninka community of the Tambo River. Key informants involved in maternal health care were selected, and 60 in-depth interviews were conducted that explored geographical, financial, cultural, and organizational accessibility. The interviews were recorded and transcribed into a word processor; then, a content analysis was performed to classify the texts according to the dimensions of specified accessibility.

RESULTS

Geographical accessibility: health units in the territory do not have the resolution capacity to attend maternal health problems. Financial accessibility: the programs implemented by the government have not been able to finance the indirect costs of care, such as transportation, which has high costs that a family cannot afford, given their subsistence economy. Cultural: there are efforts for cultural adaptation of maternal care, but its implementation needs to be improved, and the community cannot recognize it due to the lack of continuity of the model and the high personnel turnover. Organizational: health units are characterized by insufficient human resources, supplies, and medicines that fail to offer continuous and quality care.

CONCLUSIONS

The poor geographical, financial, cultural, and organizational accessibility that women from the Asháninka community face for maternal care in public health services are evident. So, the Peruvian government must review the implementation processes of its models of care and maternal health programs in these communities and propose strategies to improve the coverage, quality and continuity of maternal care.

Waterborne diseases and ethnic-related disparities: A 10 years nationwide mortality and burden of disease analysis from Ecuador

Background

Despite worldwide progress in terms of clean water supply, sanitation, and hygiene knowledge, some middle and most of low-income countries are still experiencing many diseases transmitted using unsafe water and the lack of sanitation.

Methods

To understand the impact of all waterborne diseases (WBD) registered in Ecuador. We performed a population-based analysis of all cases and deaths due to WBD in Ecuador based on the national public databases of hospital discharges as a proxy of incidence, in-hospital mortality, and countrywide general mortality rates from 2011 to 2020.

Results

In Ecuador, mestizos (mixed European and Indigenous American ancestry) had the greatest morbidity rate (141/100,000), followed by indigenous (63/100,000) and self-determined white patients (21/100,000). However, in terms of mortality, indigenous population have the greatest risk and rates, having a 790% additional mortality rate (2.6/100,000) than the reference group (self-determined white populations) at 0.29/100,000. The burden of disease analysis demonstrated that indigenous had the highest burden of disease caused by WBD with 964 YLL per every 100,000 people while mestizos have 360 YYL per 100,000 and self-determined white Ecuadorians have 109 YYL per 100,000.

Conclusions

In Ecuador, waterborne diseases (WBD) are still a major public health problem. We found that indigenous population had higher probability of getting sick and die due to WBD than the rest of the ethnic groups in Ecuador. We also found that younger children and the elderly are more likely to be admitted to the hospital due to a WBD. These epidemiological trends are probably associated with the lower life expectancy found among Indigenous than among the rest of the ethnic groups, who die at least, 39 years earlier than the self-determined white populations, 28 years earlier than Afro-Ecuadorians and 12 years earlier than the mestizos.

Health care utilization differences between First Nations people and the general population with inflammatory bowel disease: a retrospective cohort study from Saskatchewan, Canada

BACKGROUND

Indigenous people in Canada often face barriers to access specialized care, with limited data in evaluating health care utilization among Indigenous people with inflammatory bowel disease (IBD). We aimed to compare health care utilization between First Nations patients and those in the general population diagnosed with IBD in Saskatchewan.

METHODS

We conducted a patient-oriented, population-based, retrospective cohort study by linking administrative health databases of Saskatchewan between fiscal years 1998/99 and 2017/18. We designed and completed this study in partnership with Indigenous patients and family advocates. We applied a validated algorithm to identify IBD incident cases and then used the self-declared First Nations status variable to divide those cases. We applied a 1:5 ratio for age and sex matching and used Cox proportional models to assess associations. Hazard ratios (HRs) and 95% confidence intervals (CIs) were reported.

RESULTS

We created a matched cohort with 696 IBD incident cases: 116 First Nations patients and 580 patients in the general population. We observed differences between the groups for IBD-specific hospital admissions (HR 1.33, 95% CI 1.01-1.75), IBD-related hospital admissions (HR 1.55, 95% CI 1.20-2.01), medication claims for IBD (HR 0.52, 95% CI 0.41-0.65) and 5-aminosalicylic acid claims (HR 0.56, 95% CI 0.45-0.71) adjusting by rural or urban residence and diagnosis type. There were no significant differences in the hazard rate of outpatient gastroenterology visits (HR 1.13, 95% CI 0.90-1.41), colonoscopies (HR 1.14, 95% CI 0.92-1.41) and surgeries for IBD (HR 1.14, 95% CI 0.80-1.64).

INTERPRETATION

We identified that First Nations patients diagnosed with IBD had a higher rate of hospital admissions owing to IBD than patients in the general population diagnosed with IBD. We also found an inverse association between First Nations status and having prescription medication claims for IBD.

COVID-19 among Amazonian indigenous in Peru: mortality, incidence, and clinical characteristics

Background

Few studies have described the clinical characteristics of patients with COVID-19 from ethnic minority groups. Our objective was to evaluate the mortality and incidence rates, clinical characteristics and factors associated with mortality in cases with COVID-19 belonging to the Amazonian indigenous ethnic group in Peru.

Methods

We performed a retrospective cohort study including all cases from COVID-19 among Peruvian people identified as Amazonian indigenous from 07 March to 31 October 2020. We calculated the standardized mortality and incidence ratios using the indirect age-adjusted method to determine the differences between Amazonian Indigenous and the general population. In addition, we used multivariable logistic regression to determine the risk factors for death.

Results

A total of 19 018 laboratory confirmed COVID-19 cases were analyzed. Indigenous people had 3.18 (95% CI, 3.13–3.23) times the risk of infection and 0.34 (0.31–0.37) times the mortality risk of the general Peruvian population. Males had 1.29 (1.04–1.61) times the odds of death compared with females and for each year of age, the odds of mortality increased 1.03 (1.03–1.04) times. Cases with respiratory distress had 2.47 (1.96–3.10) times more likely to die. Having an immunodeficiency was 18.7 (6.12–57.00) times more likely to die.

Discussion

The Amazonian indigenous population in Peru was strongly affected by COVID-19 compared with the general Peruvian population.

Teacher plants - Indigenous Peruvian-Amazonian dietary practices as a method for using psychoactives

ETHNOPHARMACOLOGICAL RELEVANCE

Indigenous groups of the Amazon have developed intricate methods for the application of psychoactives, among which particularly the dieta or diet method of Peruvian-Amazonian traditional medicine stands out. It is a retreat-like intervention involving lengthy periods of social, behavioural, and alimentary restrictions, while ingesting specially prepared plant substances. The interplay of the dietary conditions and plants ingested sensitizes the dieter to receive healing, strength, guidance, and knowledge. From a clinical scientific point of view, the method has remained largely underexplored, but seems more pertinent than ever given the increasing interest in Amazonian psychoactive preparations including ayahuasca (Banisteriopsis caapi) and the burgeoning field of psychedelic-assisted therapies in general.

AIM OF THE STUDY

This study offers a descriptive account and emic interpretation of the Peruvian-Amazonian dieta. More specifically we document in detail the procedure, its context and purpose of application, effects, modes of action, adverse effects, and risks, from the perspectives of a sample of Peruvian traditional healers. The Peruvian-Amazonian dieta is a multi-purpose method for making use of medicinal plants, many of which (but not all), are psychoactive; the current work especially focuses on its therapeutic applications in conjunction with psychoactives.

METHODS

We interviewed 16 healers working in the Ucayali, San Martín, and Loreto provinces of Peru using a semi-structured interview approach. Interviews were audio-recorded and transcribed verbatim. The extensive data derived from these interviews were analysed by means of computer-assisted manifest qualitative content analysis using a theory-advancing approach. Over 500 coded text segments were categorized, resulting in 7 main theme clusters and corresponding sub-themes.

RESULTS

The interviewed healers described a complex intervention with multifaceted applications (treatment, prevention, training) and effects in various domains (body, mind, spirit, energy). The process was portrayed as transformative, with benefits attributed to the effects of the so-called teacher plants in conjunction with the diet's conditions, along with the skill of the healer guiding the intervention. Further, a detailed risk assessment revealed sophisticated safety measures and tools designed to address adverse responses. The importance of adequate training of the healer that administers the diet was particularly highlighted in this context.

CONCLUSIONS

The dieta is a central therapeutic concept and tool in Peruvian-Amazonian traditional medicine and a unique method for using psychoactive plants. Multidisciplinary health research that includes traditional treatment methods from Indigenous cultures, Amazonian and other, should not be neglected in the current global interest in psychedelic therapies; such research may in the long-term contribute to a more inclusive psychedelic research paradigm as well as healthcare practice in countries where rich traditional healing systems exist, and perhaps beyond. It may also contribute to the recognition of the Indigenous healers as not only historical forerunners, but also current leading experts in psychedelic medicine.

Time-Varying Effects of Meteorological Variables on Malaria Epidemiology in the Context of Interrupted Control Efforts in the Amazon Rainforest, 2000-2017

Successful malaria control interventions, mostly based on the training of health workers, distribution of insecticide-treated nets, and spraying, decrease malaria incidence; however, when these interventions are interrupted, a resurgence may occur. In the Peruvian Amazon, after discontinuing the control activities implemented by the PAMAFRO project (2006–2010)-a Global Fund-sponsored project for the strengthening of malaria control and surveillance in multiple countries in Latin America– malaria cases re-emerged dramatically. In parallel, meteorological factors determine the conditions suitable for the development, reproduction, and survival of mosquito vectors and parasites. This study hypothesized that interruption of malaria interventions may have modified the meteorological-malaria relationships over time (i.e., temporal changes in the dose-response between meteorological variables and malaria incidence). In this panel data analysis, we assessed the extent that relationships between meteorological variables and malaria changed temporally using data of monthly malaria incidence due to Plasmodium vivax or P. falciparum in Loreto, Peru (2000–2017). Generalized additive models were used to explore how the effects of meteorological variables changed in magnitude before, during, and after the PAMAFRO intervention. We found that once the PAMAFRO intervention had been interrupted, the estimated effects (dose-response) of meteorological variables on incidence rates decreased for both malaria parasite species. However, these fitted effect estimates did not reach their baseline levels (before the PAMAFRO period); variations of time-varying slopes between 0.45 and 2.07 times were observed after the PAMAFRO intervention. We also reported significant heterogeneity in the geographical distributions of malaria, parasite species, and meteorological variables. High malaria transmission occurred consistently in the northwestern provinces of Loreto Department. Since the end of the PAMAFRO period, a higher effect of precipitation and actual evapotranspiration was described on P. falciparum compared to P. vivax. The effect of temperature on malaria was greater over a shorter time (1-month lag or less), compared with precipitation and actual evapotranspiration (12-month lag). These findings demonstrate the importance of sustained malaria control efforts since interruption may enhance the links between meteorological factors and malaria. Our results also emphasize the importance of considering the time-varying effect of meteorological factors on malaria incidence to tailor control interventions, especially to better manage the current and future climate change crisis.

Snakebites in Rural Areas of Brazil by Race: Indigenous the Most Exposed Group

Animal stings are environmental hazards that threaten millions annually and cause a significant socioeconomic impact. Snakebite envenoming affects 2.7 million people globally every year, mostly the poorest and rural communities, with approximately 27,000 annual cases in Brazil. This study’s objective is to identify the most exposed racial group for snakebites in rural areas of Brazil and analyze possible differences in the outcome of an accident. A retrospective epidemiological study was conducted using a database of rural snakebite cases from Brazil’s Ministry of Health (2017). Descriptive analysis and a regression model were performed to examine the association of bad outcomes after a snakebite with several covariables. While mixed-race individuals presented the highest number of cases (61.79%), indigenous and white populations were the racial groups with the highest and lowest exposure rates (194.3 and 34.1 per 100,000 population, respectively). The fatality rate was 3.5 times higher in the indigenous population compared to the white population. In the multivariable model, the number of hours between the accident and health care received and the case classification suggested an association with a bad outcome. Snakebite is prominent in Brazil, particularly among indigenous groups. Antivenom is available in the Brazilian Health System; however, efforts need to be made for decentralization.

Kaniuwatewara (when we get sick): understanding health-seeking behaviours among the Shawi of the Peruvian Amazon

Background

Detailed qualitative information regarding Indigenous populations’ health-seeking behaviours within Peru’s plural healthcare system is lacking. Such context-specific information is prerequisite to developing evidence-based health policies and programs intended to improve health outcomes for Indigenous populations. To this end, this study aimed to characterize health-seeking behaviours, factors affecting health-seeking behaviours, and barriers to obtaining healthcare in two Indigenous Shawi communities in Peru.

Methods

Community-based approaches guided this work, and included 40 semi-structured interviews and a series of informal interviews. Data were analysed thematically, using a constant comparative method; result authenticity and validity were ensured via team debriefing, member checking, and community validation.

Results

Shawi health-seeking behaviours were plural, dynamic, and informed by several factors, including illness type, perceived aetiology, perceived severity, and treatment characteristics. Traditional remedies were preferred over professional biomedical healthcare; however, the two systems were viewed as complementary, and professional biomedical healthcare was sought for illnesses for which no traditional remedies existed. Barriers impeding healthcare use included distance to healthcare facilities, costs, language barriers, and cultural insensitivity amongst professional biomedical practitioners. Nevertheless, these barriers were considered within a complex decision-making process, and could be overridden by certain factors including perceived quality or effectiveness of care.

Conclusions

These findings emphasize the importance of acknowledging and considering Indigenous culture and beliefs, as well as the existing traditional medical system, within the professional healthcare system. Cultural competency training and formally integrating traditional healthcare into the official healthcare system are promising strategies to increase healthcare service use, and therefore health outcomes.

Determinants of Eye Care Service Utilization among Peruvian Adults: Evidence from a Nationwide Household Survey

PURPOSE

This study analyzes the factors associated with eye care service utilization among Peruvians 50 years of age and older, measured as self-reporting of having undergone examination of visual acuity during the last 12 months.

METHODS

A secondary analysis of the 2019 Demographic and Family Health Survey (ENDES, for its acronym in Spanish) database was carried out. We estimated the weighted proportion of adults 50 years of age and older that reported having undergone a visual acuity examination in the previous 12 months and the frequency according to the variables of interest. Crude (PR) and adjusted prevalence ratios (aPR) of eye care service utilization were constructed using generalized linear models.

RESULTS

Approximately 28.8% of Peruvians 50 years of age and older underwent a visual acuity examination in the previous 12 months. Having a higher education (aPR = 1.79; 95% CI: 1.33-2.40), health insurance such as EsSalud (aPR = 1.54; 95% CI: 1.28-1.87), a previous diagnosis of cataracts (aPR = 1.86; 95% CI: 1.67-2.09) and being part of the richest wealth quintile (aPR = 2.36; 95% CI: 1.74-3.20) were associated with greater utilization of eye care services, while living in the jungle was associated with a lower likelihood of utilization of these services.

CONCLUSION

The unequal distribution of health resources within the territory and socioeconomic gaps among the population could explain our findings. Further efforts are needed to fulfill the eye health needs of the Peruvian population.

Healthcare and Health Problems from the Perspective of Indigenous Population of the Peruvian Amazon: A Qualitative Study

Indigenous communities usually experience higher levels of mortality and poorer access to healthcare services compared to non-indigenous communities. This study aims to understand the most prevalent health problems and their treatment in the Asháninka indigenous communities of the Peruvian Amazon. We conducted an ethnographic study in order to explore the perceived health problems, the use of traditional medicine and the resources offered by the official Peruvian healthcare system. Field notes and semi-structured interviews were used. A total of 16 indigenous and four non-indigenous people were interviewed, and interpretative analysis was used to identify themes. The Asháninka community is an overlooked population, which, due to distance restrictions, misconceptions and ethnical disparities, is far away from an appropriate healthcare system and is subjected to acute medical conditions such as infections and gastrointestinal problems. This group tends to seek traditional medicine, mostly herbal medications and traditional healers. The use of a health professional is seen as a last resort. Although the official Peruvian health system incorporates community participation strategies to improve the healthcare of indigenous people, the shortage of material, human resources and cultural sensitivity makes this difficult. Healthcare strategies should be devised and implemented in order to minimize health inequality in this population.

Cultural Values and the Coliform Bacterial Load of "Masato," an Amazon Indigenous Beverage

Access to safe drinking water is limited in many isolated areas, such as the Amazon where Indigenous peoples frequently reside. Identifying safe forms of drinking water accepted by the communities could have positive health benefits for Indigenous peoples. Many Amazon Indigenous peoples traditionally prepare and consume a fermented beverage called masato, which is frequently the only form of water consumption. Despite its widespread consumption and evidence of the health benefits of fermentation, masato remains poorly investigated. We partnered with a Shawi Indigenous community in the Peruvian Amazon to conduct participatory photography to research masato preparation, and to characterize key cultural features and to assess the presence of total and fecal coliform bacteria by using a membrane filter technique. Pictures show that masato preparation is a key part of cultural practices and that there are clear gender roles in the preparation process. We found that 100% of communal water sources (26/26) were contaminated with coliform bacteria; by contrast, fewer, 18% of masato samples (2/11), were positive for coliform. This exploratory study suggests that fermented beverages like masato merit further investigation as they represent an Indigenous method to improve water quality in Amazonian communities where water safety cannot be assured.

Knowledge of Cervical Cancer Prevention Among Women in Amazonian Peru

Background and Purpose: Survey-based research was conducted in Yantalo, Peru, a rural Amazonian community, to assess the knowledge base among women surrounding cervical cancer, human papilloma virus (HPV), and preventative health practices as well as to gain a better understanding of barriers to accessing care. Methods: A total of 217 women were interviewed out of the 1612 female inhabitants of Yantalo utilizing a structured interview-style questionnaire with both closed and open-ended questions. Results: Our average respondent was 41.6 years old with the equivalent of some high school education. Approximately 75% of respondents reported that they had heard of HPV and/or cervical cancer, with 44.4% reporting they had received a test to check for cervical cancer within their lifetime. When given a 10-question knowledge assessment regarding safe sex practices and cervical cancer, women obtained an average score of 57.3%. When asked about receiving the HPV vaccine, 29% reported "Yes", 59.4% reported "No", and 11.6% reported "I don't know." Although 62.6% of women indicated that they have "easy access to cervical cancer screening," 37.4% of women reported experiencing at least one barrier to accessing care. The highest reported barriers include fear of the test causing them pain and/or lack of knowledge of the necessity cervical cancer testing. Cervical cancer rates in Peru are approximately three times that in developed countries. Conclusions: Gathering data surrounding knowledge and the barriers among the female population in rural communities is essential to developing targeted initiatives that address pertinent obstacles within these and other vulnerable communities.

Assessment of the Feasibility and Acceptability of Using Water Pasteurization Indicators to Increase Access to Safe Drinking Water in the Peruvian Amazon

Approximately two billion people lack access to microbiologically safe drinking water globally. Boiling is the most popular household water treatment method and significantly reduces diarrheal disease, but is often practiced inconsistently or ineffectively. The use of low-cost technologies to improve boiling is one approach with potential for increasing access to safe drinking water. We conducted household trials to evaluate the feasibility and acceptability of water pasteurization indicators (WAPIs) in the Peruvian Amazon in 2015. A total of 28 randomly selected households were enrolled from a rural and a peri-urban community. All households trialed two WAPI designs, each for a 2-week period. Ninety-six percent of participants demonstrated the correct use of the WAPIs at the end of each trial, and 88% expressed satisfaction with both WAPI models. Ease of use, short treatment time, knowledge of the association between WAPI use and improved health, and the taste of treated water were among the key factors that influenced acceptability. Ease of use was the key factor that influenced design preference. Participants in both communities preferred a WAPI with a plastic box that floated on the water's surface compared with a WAPI with a wire that was dipped into the pot of drinking water while it was heating (77% versus 15%, P < 0.001); we selected the box design for a subsequent randomized trial of this intervention. The high feasibility and acceptability of the WAPIs in this study suggest that these interventions have potential to increase access to safe water in resource-limited settings.

Socio-demographic inequalities in the uptake of Papanicolaou tests in Peru: analysis of the 2015-2017 Demographic and Family Health Survey

OBJECTIVES

This study was conducted to analyze the inequalities in Papanicolaou test (also referred to as the Pap smear) uptake according to the socio-demographic characteristics of Peruvian women 30 years to 59 years of age using information from the 2015-2017 Demographic and Family Health Survey (ENDES, acronym in Spanish).

METHODS

This is an analytical, cross-sectional study based on information acquired from the 2015-2017 ENDES surveys. Socio-demographic characteristics were reported using absolute frequencies and weighted proportions with 95% confidence intervals, considering results with a p-value <0.05 as statistically significant. Concentration curves (CCs) and concentration indices (IndCs) were created based on the interaction of the wealth index and uptake of Pap smears, taking into account the different characteristics of the population studied for the measure of inequalities.

RESULTS

All the CCs were distributed below the line of equality. Similarly, all the IndCs were higher than zero, indicating inequality in the uptake of Pap smears, favoring those with a higher wealth index. The highest IndC values were obtained from women aged 50-59 (IndC, 0.293), those who lived in the jungle (IndC, 0.230), and those without health insurance (IndC, 0.173).

CONCLUSIONS

We found socio-demographic inequalities in the uptake of Pap smears in Peru, favoring women with a higher wealth index. More funding is needed to promote cervical cancer screening programs and to create systems that ensure equal access to healthcare in Peru.

Expanding Medical Education for Local Health Promoters Among Remote Communities of the Peruvian Amazon: An Exploratory Study of an Innovative Program Model

PURPOSE

Community health workers (CHWs) play integral roles in primary health care provision in low- and middle-income countries (LMICs). This is particularly true in underdeveloped areas where there are acute shortages of health workers. In this study, we evaluated the development and community utilization of a CHW training program in the Loreto province of Peru. Additionally, a community-oriented training model was designed to augment access to basic health information in underserved and isolated areas of the Amazon.

METHODS

Health resource utilization was compared in each community by surveying community members before and after implementation of the CHW training program, which utilized a community participatory program development (CPPD) model.

RESULTS

All communities demonstrated significantly increased CHW utilization (p = 0.026) as their initial point of contact for immediate health concerns following CHW training implementation. This increase in CHW utilization was accompanied by trends toward decreased preferences for local shamans or traveling to the closest health post as the initial health resource.

CONCLUSION

The community-focused, technology-oriented model utilized in this study proved an effective way to promote the use of CHWs in the Amazon region of Loreto, and could prove valuable to CHW capacitation efforts within other Peruvian provinces and in other LMICs around the world.

Factors associated with highly effective contraceptive use among reproductive-age women in Peru: Evidence from a nationwide survey

OBJECTIVE

This study aimed to assess the factors associated with highly effective contraceptive (HEC) use among reproductive-age women in Peru, using evidence from a nationwide survey.

STUDY DESIGN

We analyzed the data corresponding to a national representative sample of 30,169 Peruvian women aged 15-49 years, surveyed during the Demographic and Family Health Survey, 2017. Usage of HEC methods included pills, IUD, injections, sterilization and implant. We assessed the factors associated with its use using Poisson regression models, reporting the crude (cPR) and adjusted prevalence ratios (aPR) with their respective 95 % confidence intervals (95 % CI).

RESULTS

The prevalence of HEC use was 29.9 %. Factors related to a more likely use of HEC methods were having one (aPR: 4.03; 95 % CI: 3.19-5.09) or more children (aPR: 5.60; 95 % CI: 4.42-7.09), and having a health insurance children (aPR: 1.14; 95 % CI: 1.05-1.24). Women from the highlands (aPR: 0.74; 95 % CI: 0.67-0.81), aged ≥35 years (aPR: 0.78; 95 % CI: 0.67-0.90), not currently married or cohabiting (aPR: 0.52; 95 % CI: 0.47-0.58), and who considered it really hard to have to take transportation when they need medical help or advice (aPR: 0.92; 95 % CI: 0.86-0.99) were less likely to use highly effective contraception.

CONCLUSION

Quality and access to reproductive health is still a challenge in Peru. Family planning programs should be better disseminated and integrated. Similarly, promotion of educational campaigns and easy access to HEC methods are needed.

Malaria risk assessment and mapping using satellite imagery and boosted regression trees in the Peruvian Amazon

This is the first study to assess the risk of co-endemic Plasmodium vivax and Plasmodium falciparum transmission in the Peruvian Amazon using boosted regression tree (BRT) models based on social and environmental predictors derived from satellite imagery and data. Yearly cross-validated BRT models were created to discriminate high-risk (annual parasite index API > 10 cases/1000 people) and very-high-risk for malaria (API > 50 cases/1000 people) in 2766 georeferenced villages of Loreto department, between 2010-2017 as other parts in the article (graphs, tables, and texts). Predictors were cumulative annual rainfall, forest coverage, annual forest loss, annual mean land surface temperature, normalized difference vegetation index (NDVI), normalized difference water index (NDWI), shortest distance to rivers, time to populated villages, and population density. BRT models built with predictor data of a given year efficiently discriminated the malaria risk for that year in villages (area under the ROC curve (AUC) > 0.80), and most models also effectively predicted malaria risk in the following year. Cumulative rainfall, population density and time to populated villages were consistently the top three predictors for both P. vivax and P. falciparum incidence. Maps created using the BRT models characterize the spatial distribution of the malaria incidence in Loreto and should contribute to malaria-related decision making in the area.

Health service utilization, perspectives, and health-seeking behavior for maternal and child health services in the Amazon of Peru, a mixed-methods study

Background

Various factors influence health service utilization at the community level. Research on the barriers to uptake of local health services is essential to reduce maternal and child mortality and morbidity. The Amazon region of Peru has some of the poorest health indicators in the country. The current study set out to better understand the health-seeking behavior and perspectives of mothers in Amazonian communities, exploring individual- and contextual-level barriers for seeking care at local health facilities for common maternal and child health issues.

Methods

The study employed a mixed-methods design by conducting 50 structured interviews with mothers of children under the age of 4. The study took place in 5 communities in Loreto, Peru. The quantitative data was analyzed with descriptive statistics to identify participants’ socio-demographic characteristics and reported utilization of health services. The qualitative data was analyzed in three rounds: inductive codebook development, application of the codebook, and thematic synthesis to contextualize the quantitative results and better understand the perspectives of the mothers regarding maternal and child health issues and the local health services.

Results

Overall, reported health service utilization among study participants was relatively high. However, the mothers identified several individual- and contextual-level factors that may affect their experiences and the health-seeking behaviors of other mothers in their communities: (i) embarrassment, fear, and trust, (ii) insufficient number and poor attitudes of health personnel, (iii) limited supply of basic medicines and materials in the health facility, and (iv) low demand for family planning services and limited awareness of adolescent-specific services.

Conclusion

Several findings in the current study reflect the reduced conditions of health services, while others display that many mothers maintain a positive outlook on the health services available to them and are proactive in the care of their child. The study provides valuable insight into the use of local health services and the common perspectives that are hindering further uptake at the community level in the Amazon of Peru, with important implications for health policy.

A descriptive analysis of health practices, barriers to healthcare and the unmet need for cervical cancer screening in the Lower Napo River region of the Peruvian Amazon

OBJECTIVES

To undertake an descriptive analysis of the health needs, healthcare practices and barriers to accessing healthcare faced by women in Lower Napo River Region, Peru, and to understand health literacy regarding cervical cancer and the need for more effective cervical cancer screening services.

METHODS

We performed a community-based needs assessment adapting Demographic and Health survey methodology with additional questions determining female health literacy on cervical cancer and assessing the availability and need for cervical cancer screening services. We surveyed women (N = 121) across all households in six communities along the Lower Napo River, Loreto, Peru, in May 2015. Data were collected as part of the larger Amazon Community Based Participation Cervical Cancer Screen-and-Treat Programme. Survey data were compared to national results from ENDES 2014.

RESULTS

Comparison between our findings and the ENDES 2014 survey highlighted considerable inequality between indigenous or mixed indigenous, rural populations in Loreto, Peru, and national population data averages over level of formal education, literacy, barriers to accessing healthcare and maternal and sexual health. Even though only 5.9% (N = 7/117) of women had no formal health insurance coverage, money was reported as the leading barrier accessing healthcare (N = 88/117, 75.2%). Health literacy regarding cervical and breast cancer was poor. A high proportion of women highlighted fear of screening processes (70.8%, N = 80/113) and lack of available services (53.6%, N = 60/112) as barriers to cervical cancer screening.

CONCLUSION

Although progress has been made in improving healthcare access in Peru, such gains have not been experienced equitably and women living in remote communities face persistent marginalization regarding their health. There is a significant need for education related to and screening for cervical cancer in this region that is tailored to the reality of women's lives in remote communities in Loreto.

Trends and geographic pattern of stomach cancer mortality in Peru

BACKGROUND

Stomach cancer mortality rates in South America are among the highest in the world. In Peru, stomach cancer has the highest absolute number of cancer deaths in both sexes combined. We estimated mortality rates for stomach cancer in Peru by sex and geographical region between 2008 and 2015.

METHODS

We obtained death data for stomach cancer from the Peruvian Ministry of Health database. We estimated the age-standardized mortality rate (ASMR) per 100,000 persons using the direct method and the world standard population.

RESULTS

A total of 25,020 deaths from stomach cancer were identified in the study period. At national level, stomach cancer mortality rates (per 100,000 population) for men ranged from 9.8 in 2008 to 8.8 in 2015 with a percent change of -16%, and for women from 8.8 in 2008 to 7.7 in 2015 with a percent change of -16.8%. The highlands had the highest mortality rates overall, mainly in Huancavelica and Huánuco. The rainforest had the lowest rates and the highest decline in stomach cancer ASMRs. The coast displayed intermediate rates overall.

CONCLUSIONS

Within the study period, mortality rates from stomach cancer in Peru declined by 16%. The highlands had the highest mortality rates as compared to those from the coast or rainforest region. These geographical differences in mortality could reflect a different distribution in stomach cancer risk factors as the prevalence of H. pylori, poor dietary habits, low socioeconomic background of the Andean population and the lack of a decentralized health system.

Health and Demographic Characteristics of Patients Attending a Newly-Opened Medical Facility in a Remote Amazonian Community: A Descriptive Study

Peru is a country with wide regional disparities in health. Remote Amazonian communities have high rates of poverty and poor access to health services. There is a lack of data on morbidity and use of health services in the region. We describe a descriptive, cross-sectional study of the demographic characteristics and presenting complaints of attendees to a newly-opened primary care facility in a remote community. This was supplemented by structured interviews of adult attendees to build a picture of sociocultural determinants of health locally, including engagement with traditional forms of medicine. Our study provides novel insights into an under-studied and under-resourced area. We found a young population with a high prevalence of infectious illnesses, particularly dermatological infections - a previously under-recognised source of morbidity in these communities. Poor literacy rates and widespread use of traditional forms of medicine have important implications for the provision of healthcare in this region.

Urban Youth Knowledge and Attitudes Regarding Lead Poisoning

Environmental health literacy (EHL) is a promising and evolving field of research that could benefit from youth engagement. Yet studies focused on youths' environmental health awareness and concerns are limited. For example, although lead exposure remains a threat to youth development in urban environments, no published studies have measured urban youth's knowledge of lead poisoning. A CBPR partnership established a youth advisory council (YAC) who helped to design, interpret and disseminate a mixed methods study exploring environmental health perceptions among urban youths ages 10-18. Surveys assessed awareness, attitudes, and knowledge regarding lead poisoning and five environmental health issues determined by the YAC. Focus group questions further contextualized youths' lead knowledge and understanding of youths' environmental health concerns. A majority of youth could identify specific sources of lead exposure but had minimal knowledge of prevention strategies, and focus group data revealed misinformation regarding lead sources and consequences. Survey and focus group respondents' level of awareness and concern regarding YAC-selected EH issues was high in comparison to lead poisoning. In particular, job opportunities and police brutality were endorsed as both neighborhood concerns and priorities. Awareness and knowledge of environmental health issues among urban youth have not been well described. These findings reinforce the importance of addressing problems of local relevance. Moving forward, lead poisoning prevention education for youth and youth EHL partnerships may benefit from incorporating an ecological approach wherein connections to the social and economic context are made explicit.

[Primary health care for South-American indigenous peoples: an integrative review of the literatureAtención primaria en salud a indígenas de América del Sur: revisión integrativa de la bibliografía]

Objective

To review the literature regarding the access to primary health care (PHC) by indigenous communities in South America, identifying the main access barriers.

Method

Integrative review of articles published from 2007 to 2017 in the LILACS, PubMed, and SciELO databases. The search terms "indigenous AND health AND Brazil" and "indigenous AND health NOT Brazil" were used in Portuguese and English. Articles published in English, Portuguese, or Spanish, focusing strictly on PHC and on South-American indigenous populations were included.

Results

Forty articles describing aspects of PHC for indigenous populations in eight countries - Brazil, Peru, Colombia, Bolivia, Argentina, Chile, Paraguay, and Ecuador - were included. The main barriers to accessing PHC were the difficulty of reaching the health care facilities closest to villages; difficulty in communicating with health care professionals; inadequate transportation to the health care units; lack of epidemiological data on indigenous villages; lack of information regarding local indigenous cultures; and fear of discrimination or humiliation on the part of indigenous patients.

Conclusions

Studies regarding the health of indigenous populations in South America are scarce. It is evident that national health systems still need to advance towards an intercultural medicine that respects the social, cultural, and economic realities of all communities, with knowledge and consideration for different forms of care.

Developmental delay in the Amazon: The social determinants and prevalence among rural communities in Peru

The consequences of poor child development are becoming increasingly recognized. Programs are being put in place around the world to improve child development by providing healthy and stimulating environments for children. However, these programs often have limited reach and little is known about the prevalence of developmental delay in under-developed communities. The current study set-out to better understand the prevalence of developmental delay in rural communities in the Amazon region of Peru. Also, it explores social determinants that are associated with any delay. Cross-sectional study by evaluating developmental delay in children under 4 years utilizing Ages and Stages Questionnaire (ASQ-3). Additionally, conducting a social determinants questionnaire answered by caretakers to identify social drivers for developmental delay. The data was analyzed with multi-variant analysis to measure association. The prevalence of developmental delay in the Amazonian communities was 26.7% (19.3% in communication, 11.4% in gross motor skills, 8% in both) (N = 596). The multivariate logistic regression analysis revealed significant associations between developmental delay and; level of education (OR 0.64, p = 0.009), age of mother during child's birth (OR 0.96, p = 0.002), visits by community health agents (OR 0.73, p = 0.013), and river as primary water source (OR 2.39, p = 0.001). The social determinants questionnaire revealed that 39% of the mothers had their first child before the age of 17, nearly half stopped going to school before the age of 12 (52%), 29% gave birth at home, 13% breast fed for less than 7 months, and 50% of the children had diarrhea in the last month. There is still a great need to improve the conditions for child development in the Amazon region of Peru. One-fourth of the children suffer from developmental delay, which will likely impede their potentials for life unless something is done. The impact of education, age of mother at birth of the child, community health agents, and access to clean drinking water were important findings. Improvements can be made in these areas to create a large, cost-effective impact on the well-being of the communities.

HIV and syphilis in the context of community vulnerability among indigenous people in the Brazilian Amazon

BACKGROUND

Contextual factors shape the risk of acquiring human immunodeficiency virus (HIV) and syphilis. We estimated the prevalence of both infections among indigenous people in nine indigenous health districts of the Brazilian Amazon and examined the context of community vulnerability to acquiring these infections.

METHODS

We trained 509 health care workers to screen sexually active populations in the community for syphilis and HIV using rapid testing (RT). We then assessed the prevalence of HIV and syphilis using RT. A multivariable analysis was used to identify factors associated with syphilis infection (sociodemographic, condom use, intrusion, population mobility, and violence).

RESULTS

Of the 45,967 indigenous people tested, the mean age was 22.5 years (standard deviation: 9.2), and 56.5% were female. Overall, for HIV, the prevalence was 0.13% (57/43,221), and for syphilis, the prevalence was 1.82% (745/40,934). The prevalence in men, women, and pregnant women for HIV was 0.16%, 0.11%, and 0.07%, respectively, and for syphilis, it was 2.23%, 1.51%, and 1.52%, respectively. The district Vale do Javari had the highest prevalence of both infections (HIV: 3.38%, syphilis: 1.39%). This district also had the highest population mobility and intrusion and the lowest availability of prenatal services. Syphilis infection was independently associated with age (odds ratio [OR] 1.04, 95% confidence interval [CI]: 1.03-1.05), male sex (OR 1.32, 95% CI: 1.14-1.52), and mobility (moderate: OR: 7.46, 95% CI: 2.69-20.67; high: OR 7.09, 95% CI: 3.79-13.26).

CONCLUSIONS

The large-scale integration of RT in remote areas increased case detection among pregnant women, especially for syphilis, in districts with higher vulnerability. Mobility is an important risk factor, especially in districts with higher vulnerability. Contextually appropriate approaches that address this factor could contribute to the long-term success of HIV and syphilis control programs.

Health, healthcare access, and use of traditional versus modern medicine in remote Peruvian Amazon communities: a descriptive study of knowledge, attitudes, and practices

There is an urgent need for healthcare research, funding, and infrastructure in the Peruvian Amazon. We performed a descriptive study of health, health knowledge and practice, and healthcare access of 13 remote communities of the Manatí and Amazon Rivers in northeastern Peru. Eighty-five adults attending a medical boat service were interviewed to collect data on socioeconomic position, health, diagnosed illnesses, pain, healthcare access, and traditional versus modern medicine use. In this setting, poverty and gender inequality were prevalent, and healthcare access was limited by long distances to the health post and long waiting times. There was a high burden of reported pain (mainly head and musculoskeletal) and chronic non-communicable diseases, such as hypertension (19%). Nearly all participants felt that they did not completely understand their diagnosed illnesses and wanted to know more. Participants preferred modern over traditional medicine, predominantly because of mistrust or lack of belief in traditional medicine. Our findings provide novel evidence concerning transitional health beliefs, hidden pain, and chronic non-communicable disease prevalence in marginalized communities of the Peruvian Amazon. Healthcare provision was limited by a breach between health education, knowledge, and access. Additional participatory research with similar rural populations is required to inform regional healthcare policy and decision-making.
