Editorial endogamy in some Latin American dental journals

Objective: Scientific publication in a journal by a member of the editorial committee of the same journal is known as authorial endogamy. To determine the presence of authorial endogamy in some Latin American dental journals. Material and Methods: Observational, descriptive, retrospective study. Eight dental journals from Brazil, Cuba and Chile indexed to Scopus in the period of 2018 - 2021 were analyzed. An evaluation was made of the manuscripts that include a member of the editorial committee as author. The results were expressed in percentages and frequency measurements and for the bivariate analysis, the Mann-Whitney U test and Fisher's exact test were used (p<0.05). Results: A total of 2026 articles, from which 14.52% (n=256), of authorial endogamy were found. The endogamy articles were mostly original articles 98.05% (n=252), experimental design 39.70% (n=102), advisory council 49.36% (n=153), co-authorship position 58.97% (n=184), with presence of 1 endogamic author per article 82.94% (n=214), the number of days from submission to acceptance were statistically lower in endogamic articles (p=0.003). Conclusion: The presence of editorial endogamy in some dental journals in Latin America was low, this finding is more frequent in original articles, mostly from the advisory board and as co-author. Additionally; it was found that endogamic articles took less days in editorial process. (AU)

Risk factors for dental caries in Latin American and Caribbean countries

Abstract Identifying the risk factors for dental caries is vital in epidemiology and clinical practices for developing effective preventive strategies, both, at the individual and collective levels. Different causality/determination models have been proposed to understand the development process of dental caries. In the present review, we designed a model inspired by the world-known social determinants models proposed in the 90s and more recently in the 10s, wherein the contextual factors are placed more externally and encompass the individual factors. The contextual factors included those related to the cultural and societal values, as well as the social and health government policies. The individual factors were classified into the following categories: socioeconomic (social class, occupation, income, and education level), demographic characteristics (age, sex, and ethnicity), behavioral factors (non-use of fluoride dentifrice, sugar consumption, poor oral hygiene, and lack of preventive dental care), and biological factors (recent caries experience/active caries lesions, biofilm retentive factors, developmental defects of the enamel, disabilities, saliva amount and quality, cariogenic biofilm). Each of these variables was addressed, while focusing on the current evidence from studies conducted in Latin American and Caribbean countries (LACC). Based on the proposed model, educational aspects were addressed, and individual caries risk assessment and management decisions were proposed; further, implications for public health policies and clinical practice were described. The identification of modifiable risk factors for dental caries should be the basis for multi-strategy actions that consider the diversity of Latin American communities.

Management of dental caries lesions in Latin American and Caribbean countries

Abstract Caries management at the lesion level is dependent on the lesion activity, the presence of a cavitation (either cleanable or non-cleanable), and lesion depth as evaluated via radiographic examination. A variety of non-invasive, micro-invasive, and minimally invasive treatment (with or without restoration) options are available for primary and permanent teeth. Non-invasive strategies include oral hygiene instructions, dietary counseling, and personal as well as professional use of fluoridated products that reduce demineralization and increase re-mineralization. Micro-invasive procedures include the use of occlusal resin sealants and resin infiltrants, while minimally invasive strategies comprise those related to selective removal of caries tissues and placement of restorations. Deep caries management includes indirect pulp capping, while exposed pulp may be treated using direct pulp capping and partial or complete pulpotomy. The aim of the present study was to review available evidence on recommended preventive and restorative strategies for caries lesions in Latin American/Caribbean countries, and subsequently develop evidence-based recommendations for treatment options that take into consideration material availability, emphasize ways to adapt available treatments to the local context, and suggest ways in which dentists and health systems can adopt these treatments.

Dental caries prevalence, prospects, and challenges for Latin America and Caribbean countries: a summary and final recommendations from a Regional Consensus

Abstract Dental caries can be effectively managed and prevented from developing into cavitated lesions while preserving tooth structure at all levels. However, the strong correlation between caries and socioeconomic factors may compromise the efficacy of preventive strategies. The high prevalence of persistent inequalities in dental caries in Latin American and Caribbean countries (LACC) is a matter of concern. The estimates of the burden of disease in some countries in this region are outdated or absent. This paper aims to summarize and present the final recommendations of a regional Consensus for Dental Caries Prevalence, Prospects, and Challenges for LACC. This consensus is based on four articles that were written by a team of Latin American experts, reviewed by dental associations, and presented and discussed in two consensus events. The following domains were explored: epidemiology, risk factors, prevention strategies, and management of dental caries with a focus on restorative procedures. Dental caries can manifest throughout the lifespan of an individual, making it a matter of concern for infants, children, adults, and older people alike. The prevalence rates of untreated caries in deciduous and permanent teeth are high in many parts of the world, including LACCs. Previous evidence suggests that the prevalence of dental caries in 12-year-olds is moderate to high in most Latin American countries. Moreover, the prevalence of treatment needs and dental caries in the adult and elderly population can also be regarded as high in this region. The risk/protective factors (e.g., sugar consumption, exposure to fluoride, and oral hygiene) probably operate similarly in all LACCs, although variations in the interplay of these factors in some countries and within the same country cannot be ruled out. Although salt and water fluoridation programs are implemented in many countries, there is a need for implementation of a surveillance policy. There is also room for improvement with regard to the introduction of minimal intervention techniques in practice and public health programs. Dental caries is a marker of social disadvantage, and oral health promotion programs and interventions aimed at reducing the burden of dental caries in LACCs must consider the complexity of the socioeconomic dynamics in this region. There is an urgent need to promote engagement of stakeholders, policymakers, medical personnel, universities, dental associations, community members, and industries to develop regional plans that enhance the oral health agenda for LACCs. A list of recommendations has been presented to underpin strategies aimed at reducing the prevalence and severity of dental caries and improving the quality of life of the impacted LACC population in the near future.

Dental caries experience and its impact on quality of life in Latin American and Caribbean countries

Abstract Robust epidemiological data allow for logical interventions taken in the interest of public health. Dental caries is a major public health problem driven by increased sugar consumption and various biological, behavioral, and psychosocial factors, and is known to strongly affect an individual's quality of life. This study aims to critically review epidemiological data on the prevalence of dental caries in Latin American and Caribbean countries (LACC) and its impact on the oral health-related quality of life (OHRQoL) of the population. Although the majority of national surveys did not include all age groups and several countries reported a reduction in the prevalence of cavitated carious lesions, most nations still exhibited a high burden of decayed teeth. OHRQoL evaluation was limited to children and older adults only, and was not included in any national survey. Study heterogeneity and methodological issues hindered comparison of evidence between studies and over time, and updating national level data on caries prevalence and its impact on OHRQoL should be prioritized in LACCs.

Community interventions and strategies for caries control in Latin American and Caribbean countries

Abstract Dental caries remains highly prevalent in Latin American and Caribbean countries (LACC). However, this disease can be controlled through interventions that implement evidence-based strategies in an affordable manner and that target all population groups instead of the most affluent only. Therefore, the aim of this report was to summarize the main scientifically documented community interventions and strategies based on restriction of sugars consumption, use of fluoride, and the use of occlusal sealants for caries control in LACC. A critical literature review was carried out in a systematic manner that included defined search strategies, independent review of the identified publications, and compilation of results in this report. Three systematic searches were conducted using the PubMed, LILACS, and SciELO databases to identify studies related to community interventions and strategies for caries control in LACC. Of the 37 publications identified, twenty-six focused on fluoride use, eight on occlusal sealant use, and three on the restriction of sugar consumption. Documented community interventions for sugars restriction were scarce in the region and were based on food supplementation, sugar replacement, and education. Thus, local and/or national policies should prioritize investment in upstream, coherent, and integrated population-wide policies such as taxes on sugary drinks and stronger regulation of advertising and promotion of sugary foods and drinks mainly targeting children. The main fluoride-based strategies used drinking water, refined domestic salt, cow milk, toothpaste and, to a lesser extent, mouth-rinses, acidulated phosphate fluoride (APF) gels, and varnishes to deliver fluoride to the population. Evidence of fluoride use was seen in Argentina, Belize, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, and Venezuela. Studies reporting the use of occlusal sealants were mainly located in Brazil, Chile, Colombia, Costa Rica, Peru, Mexico, and Venezuela. Community interventions restricting sugar consumption should be implemented at the individual level and through public policies. The use of fluoride must be monitored at the local, regional, and national levels so as to achieve maximum anti-caries effect while also minimizing the risk of dental fluorosis. Moreover, fluoridated water and salt programs, used as a mutually exclusive community level strategy for caries control, should expand their benefits to reach non-covered areas of the LACC while also simultaneously providing adequate surveillance of the fluoride concentration delivered to the population. Regulating the concentration of soluble fluoride (for anti-caries effect) in dentifrice formulations is also necessary in order to provide the population with an effective strategy for disease control. Targeting culturally appropriate, economically sustainable caries control interventions to rural populations and native ethnic groups such as indigenous people, quilombolas (African-origin), and riverside Amazonian people remains a crucial challenge.

Embedded implementation research determinants in Latin American health systems

ABSTRACT OBJECTIVE: To assess the determinants of embedded implementation research (EIR) conduct in seven Latin American and Caribbean countries. METHODS: This qualitative interpretative study conducted and analyzed 14 semi-structured interviews based on a grounded theory approach using Atlas-ti© 7.5.7. We grouped the conditions appointed by interviewees as determinants of EIR conduct into six domains. RESULTS: The participation of high-level engaged decision makers as research co-producers is an important EIR determinant that fosters research use. Nevertheless, EIR faces challenges such as dealing with key personnel changes and fluctuating political contexts. CONCLUSIONS: Despite its limitations, EIR is effective in creating a sense of ownership of research results among implementers, which helps bridge the gap between research and decision-making in health systems.

Climate change and environmental health in undergraduate health degrees in Latin America / Cambio climático y salud ambiental en carreras de salud de grado en Latinoamérica

ABSTRACT OBJECTIVE: Analyze the incorporation of climate change and environmental health courses in the curriculum grids of Medicine, Nursing, Nutrition and Clinical Psychology undergraduate courses in Latin American universities. METHODS: Descriptive and cross-sectional document review. Curriculum grids of the top ten Latin American universities were analyzed according to the rankings of QS Latin American University 2020, Times Higher Education World University 2020 and Academic Ranking of World Universities 2019. The presence of courses related to climate change and environmental health was sought in each curriculum grid. RESULTS: 104 of the 161 universities included in the study offered Medicine courses, 93 Nursing courses, 77 Nutrition courses and 118 Clinical Psychology courses. Most of the curriculum grids incorporated courses in public health and/or epidemiology (more than 70%); however, between 22% and 41% included courses on environmental health, and only one curriculum grid had a course on climate change in Medicine and Nursing (1%). CONCLUSIONS: Courses on climate change and environmental health have been scarcely introduced in the curriculum grids of the health field in Latin American universities. This could weaken the important role that health professionals play in providing health care to the population.

RESUMEN OBJETIVO: Analizar la incorporación de cursos de cambio climático y salud ambiental en las mallas curriculares del grado en Medicina, Enfermería, Nutrición y Psicología clínica en universidades latinoamericanas. MÉTODOS: Revisión documental de tipo descriptiva y transversal. Se analizaron las mallas curriculares de las diez primeras universidades latinoamericanas según los rankings QS Latin American University 2020, Times Higher Education World University 2020 y Academic Ranking of World Universities 2019. En cada malla curricular se buscó la presencia de cursos relacionados al cambio climático y la salud ambiental. RESULTADOS: De las 161 universidades que se incluyeron en el estudio, 104 ofrecían la carrera de Medicina, 93 de Enfermería, 77 de Nutrición y 118 de Psicología clínica. La mayor parte de las mallas curriculares incorporaron cursos de salud pública y/o epidemiología (más del 70%), sin embargo, entre el 22% y el 41% incluyeron cursos de salud ambiental, y solo una malla curricular tuvo un curso en cambio climático en Medicina y Enfermería (1%). CONCLUSIONES: Los cursos de cambio climático y salud ambiental han sido introducidos, de forma escasa, en las mallas curriculares del campo de la salud en universidades latinoamericanas. Esto podría debilitar el importante rol que cumplen los profesionales de la salud en la asistencia sanitaria a la población.

School-based obesity prevention interventions in Latin America: A systematic review

ABSTRACT OBJECTIVE To evaluate the implementation and effectiveness of school-based interventions to prevent obesity conducted in Latin America and provide suggestions for future prevention efforts in countries of the region. METHODS Articles published in English, Spanish, and Portuguese between 2000 and 2017 were searched in four online databases (Google Scholar, PubMed, LILACS, and REDALYC). Inclusion criteria were: studies targeting school-aged children and adolescents (6-18 years old), focusing on preventing obesity in a Latin American country using at least one school-based component, reporting at least one obesity-related outcome, comprising controlled or before-and-after design, and including information on intervention components and/or process. RESULTS Sixteen studies met the inclusion criteria. Most effective interventions (n = 3) had moderate quality and included multi-component school-based programs to promote health education and parental involvement focused on healthy eating and physical activity behaviors. These studies also presented a better study designs, few limitations for execution, and a minimum duration of six months. CONCLUSIONS Evidence-based prevention experiences are important guides for future strategies implemented in the region. Alongside gender differences, an adequate duration, and the combined use of quantitative and qualitative evaluation methods, evidence-based prevention should be considered to provide a clearer and deeper understanding of the true effects of school-based interventions.

Neoliberalism in Latin America: effects on health system reforms / Neoliberalismo na América Latina: efeitos nas reformas dos sistemas de saúde

ABSTRACT OBJECTIVE To analyze the recommendations of international organizations based on the Washington Consensus on health system reforms of selected countries in Latin America and the Caribbean in the 1980s and 1990s and to investigate the effects of the competitive market logic on public action in the health system. METHODS Comparative analysis of the characteristics of health system reforms conducted in the 1980s and 1990s, still seen in Brazil, Argentina, Chile, Colombia, Mexico and Peru. Data were collected by documental analysis and literature review. The systems were described based on the characteristics of: co-payment, privatization mechanisms, decentralization, fragmentation of the system, integration of funding sources and coverage of the population (universal or segmented). RESULTS The reforms were implemented differently, worsening inequalities in health service delivery systems. Changes related to the neoliberal idea of transforming public action in the direction of private logic point to the predominance of competition rules and the reduction in economic costs in all countries analyzed, contrary to the logic of universal health systems. CONCLUSION The reduction in economic costs, the fragmentation of systems and inequalities in the provision of health services, among others, may mean other future costs resulting from low protection to the population's health. A striking and multidimensional counter-reform is essential to make health a right of all again, in a solidarity system that can lead to the reduction in inequalities and a more democratic society.

RESUMO OBJETIVO Analisar as recomendações dos organismos internacionais pautadas no Consenso de Washington para as reformas dos sistemas de saúde de países selecionados da América Latina e Caribe nas décadas de 1980 e 1990 e investigar os efeitos da lógica concorrencial de mercado sobre a ação pública nos sistema de saúde. MÉTODOS Análise comparada de características das reformas dos sistemas de saúde realizadas nas décadas de 1980 e 1990, presentes até o momento no Brasil, Argentina, Chile, Colômbia, México e Peru. Os dados foram coletados por análise documental e revisão de literatura. Os sistemas foram descritos quanto às características de: copagamento, mecanismos de privatização, descentralização, fragmentação do sistema, integração das fontes de financiamento e cobertura da população (universal ou segmentada). RESULTADOS As reformas foram implementadas de forma variada, aprofundando desigualdades nos sistemas de prestação de serviços de saúde. As mudanças, ao serem relacionadas à ideia neoliberal de transformar a ação pública na direção da lógica privada, apontam para o predomínio das regras da concorrência e da redução dos custos econômicos em todos os países analisados, contrariando a lógica dos sistemas universais de saúde. CONCLUSÃO A redução dos custos econômicos, a fragmentação dos sistemas e as desigualdades na prestação de serviços de saúde, entre outros, poderão significar outros custos futuros decorrentes da baixa proteção à saúde da população. É imprescindível uma contrarreforma contundente e multidimensional, que retome a saúde como direito de todos, em um sistema solidário que possa levar à redução das desigualdades e a uma sociedade mais democrática.

Strategies for the prevention of periodontal disease and its impact on general health in Latin America. Section III: Prevention

Abstract: Dental plaque removal and the understanding of risk factors, risk indicators and social determinants are important components in the prevention of periodontal disease. Periodontal diseases and dental caries are largely preventable conditions, but require a "common risk factor approach" with non-communicable diseases with the purpose of improving their prevention and control, and positive impact on health. The aim of this consensus was to identify the evidence and gaps in periodontal prevention in Latin American, and to propose individual and collective recommendations for the population, health professionals, dental practice and government. The prevention of periodontal diseases in Latin America has mainly been focused on oral hygiene instruction, use of toothbrushes and interproximal devices, but in some patients, it is necessary to use adjuncts to these measures, such as antimicrobial and/or probiotic products that are backed by broad scientific evidence. Some evidence has shown that there are inadequate knowledge, attitudes and practices among patients, dentist and other health professionals. The prevention of periodontal diseases and caries should be adopted as a healthy lifestyle routine, because of their local and systemic effects. Recently, new empowerment strategies have been proposed in order to generate behavioral changes. Periodontal diseases can often be prevented, or controlled by joined efforts between government health systems, scientific associations, universities, health professionals, private companies and communities. In conclusion, the relations between periodontal diseases, caries, healthy lifestyles and NCD's offer an ideal opportunity to change Latin American prevention strategies at both the individual level and population levels.

Periodontal disease and its impact on general health in Latin America: LAOHA Consensus Meeting Report

Abstract: Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. However, most of these aspects are studied and discussed globally, which may hamper a clear interpretation of the findings and the design of effective plans of action for specific regions or populations. For example, in Latin America, epidemiological data about the distribution of periodontal diseases is still scarce, mainly when it comes to nationwide representative samples. This Consensus aimed to address the following topics related to periodontal diseases in Latin America: a) The impact of the global burden of periodontal diseases on health: a global reality; b) Periodontal diseases in Latin America; c) Strategies for the prevention of periodontal diseases in Latin America; d) Problems associated with diagnosis of periodontal conditions and possible solutions for Latin America; e) Treatment of Periodontitis. This consensus will help to increase awareness about diagnosis, prevention and treatment of periodontal diseases, in the context of Latin American countries.

Periodontal disease and its impact on general health in Latin America. Section V: Treatment of periodontitis

Abstract: Gingivitis and periodontitis are associated with a negative impact on Oral Health Related Quality of Life (OHRQoL), exerting a significant influence on aspects related to the patients' function and esthetics. Periodontitis has been associated with several systemic conditions, including adverse pregnancy outcomes, cardiovascular diseases, type 2 diabetes mellitus (DM), respiratory disorders, fatal pneumonia in hemodialysis patients, chronic renal disease and metabolic syndrome. The aim of this paper was to review the results of different periodontal treatments and their impacts on patients' OHRQoL and systemic health. Non-surgical and surgical periodontal treatments are predictable procedures in terms of controlling infection, reducing probing pocket depth and gaining clinical attachment. In addition, the treatment of periodontitis may significantly improve OHRQoL and promote a reduction in the levels of systemic markers of inflammation, including some cytokines associated with cardiovascular diseases. Studies have also suggested that periodontal treatment may improve glycemic control in patients with DM. Strategies and actions for preventing the onset and recurrence of periodontitis, and the challenges facing the field of periodontology in the XXI century are presented in this review.

Periodontal disease and its impact on general health in Latin America. Section II: Introduction part II

Abstract: The epidemiological data on gingivitis and periodontitis in Latin America are scarce, as the majority of the Latin American studies have analyzed probing depth instead of clinical attachment loss. Reported data have shown high variations in results between different Latin American countries, with the main causes of these differences being the clinical case definition and methodological strategies used. In general, data have revealed that the prevalence of periodontal disease is higher in Latin Americans than in populations in the USA or Europe. Regarding its relations with other diseases and conditions, some Latin American studies have focused on the association between periodontitis and adverse pregnancy outcomes, or poor glycemic control in diabetic patients; however, these studies have reported controversial results. In Chile, reports have indicated that periodontal treatment significantly reduced the preterm birth rate; however, no association between periodontitis and perinatal outcome was found in Brazil. For diabetes mellitus, Brazilian studies have reported controversial findings; however, a Chilean interventional study reported significant reductions in the glycosylated hemoglobin levels after periodontal treatment. Although epidemiological data for Latin America are scarce, the information available at present is useful for establishing national policies on health promotion, prevention, and treatment of periodontal disease. Therefore, dental schools must play a key role in educating professionals who are highly trained in the promotion, prevention, early diagnosis and treatment of periodontal disease, with an approach to risk, and strong biopsychosocial and ethical components. Thus, future Latin American dentists would be able to face the challenge of decreasing the prevalence of periodontal diseases by leading interdisciplinary health teamwork.

Latin American interventions in children and adolescents' sedentary behavior: a systematic review

ABSTRACT OBJECTIVE To identify and evaluate the effects of community-based interventions on the sedentary behavior (SB) of Latin American children and adolescents. METHODS A systematic review on community-based trials to reduce and/or control SB in Latin American countries (Prospero: CRD42017072157). Five databases (PubMed, Web of Science, Scopus, SciELO and Lilacs) and a reference lists were searched. RESULTS Ten intervention studies met the eligibility criteria and composed the descriptive synthesis. These studies were conducted in Brazil (n=5), Mexico (n=3), Ecuador (n=1) and Colombia (n=1). Most interventions were implemented in schools (n=8) by educational components, such as meetings, lessons, and seminars, on health-related subjects (n=6). Only two studies adopted specific strategies to reduce/control SB; others focused on increasing physical activity and/or improving diet. Only one study used an accelerometer to measure SB. Seven studies investigated recreational screen time. Eight studies showed statistically significant effects on SB reduction (80%). CONCLUSIONS Latin America community-based interventions reduced children and adolescents' SB. Further studies should: define SB as a primary outcome and implement strategies to reduce such behaviour; focus in different SBs and settings, other than recreational screen time or at-home sitting time; and use objective tools together with questionnaires to measure sedentary behaviour in.

Scoping review of studies on food marketing in Latin America: Summary of existing evidence and research gaps

ABSTRACT OBJECTIVE To document the evidence about marketing of ultra-processed foods and "non-alcoholic" beverages in Latin America. METHODS We performed a structured search of quantitative and qualitative studies in PubMed, SciELO and LILACS, published between January 2000 and May 2017 and conducted in Latin America. We conducted a quality assessment following a standardized tool and a thematic analysis to identify key typologies of marketing across studies RESULTS Out of 521 studies screened by title and abstract, we included 36 in this review; 27 of them analyzed television advertisement. Other marketing channels studied were food packaging, point of sale and outdoor advertisement. Studies found television advertises foods and beverages that are mostly ultraprocessed foods and have low nutritional value, particularly those promoted during children's programming. We also observed children have a literal interpretation of images printed on food packaging, so this can be deceiving. Several studies also found proximity to unhealthy foods may increase their consumption. Finally, the thematic analysis identified the following typologies of food marketing: a) television advertisement, b) food packaging marketing, c) marketing strategies at points of sale and d) other marketing strategies. We found almost no advertisements for unprocessed or minimally processed foods such as fruits and vegetables. We did not find any studies on digital marketing conducted in the region. CONCLUSIONS This review found that the main channel of food marketing was television advertising. This synthesis provides insights to the challenges unhealthy eating represents to the public health of Latin America and identifies knowledge gaps to guide future research.

Epidemiologia da doença periodontal na América Latina / Epidemiology of periodontal disease in Latin America

Doença periodontal é uma infecção que pode levar a perda do periodonto de maneira irreversível e, em seus estágios mais avançados, resultar na perda do elemento dentário. Por isso, estudos sobre a prevalência da doença periodontal são de grande importância para que profissionais, leigos e governantes possam identificar a prevalência e a severidade da doença e ainda, traçar estratégias de saúde individuais e comunitárias de prevenção, tratamento e controle da doença periodontal. O objetivo da presente revisão foi analisar os aspectos epidemiológicos desta doença e a sua distribuição na América Latina. Diversos estudos foram empregados na avaliação periodontal de indivíduos de diferentes idades e localidades geográficas. Com base nos resultados e observações dos trabalhos apresentados, a doença periodontal na forma de gengivite ou periodontite, parece ser altamente prevalente na população. Estas observações são, no entanto, derivadas de estudos realizados em um limitado número de localidades. São necessários mais estudos epidemiológicos para traçar com exatidão o perfil desta doença na população da América Latina.
