RESUMEN
Using baseline data of the Engage Cohort Study, a Canadian study of sexually active gay, bisexual and other men who have sex with men (GBM), we evaluated the association between sexual behavior and risk perception among HIV-negative participants and whether HIV treatment optimism moderated this relationship. Participants were recruited by respondent-driven-sampling (RDS). We defined high-risk sexual behavior in the past six months as any condomless anal sex with a casual partner (i.e. not the participant's main partner) with either unknown HIV-status where neither used pre-exposure prophylaxis or with a partner living with HIV having detectable/unknown viral load. We assessed HIV treatment optimism-skepticism using a 12-item scale. RDS-II-weighted adjusted logistic regression models examined associations with risk perception measured by the question "How would you assess your current risk of getting HIV?" (response options were on a 6-point Likert-scale ranging from "very unlikely" to "very likely", dichotomized into "No Perceived Risk" (very unlikely/unlikely) and "Perceived Risk" (somewhat likely/likely/very likely/I think I already have HIV). Of 1961 participants, engagement in high-risk sexual behavior was reported by 155 (17.0%), 62 (12.4%), 128 (17.2%) of participants in Montréal, Toronto, and Vancouver, respectively. High-risk sexual behavior increased the odds of perceived HIV risk (pooled adjusted odds ratio = 2.9, 95%CI = 2.2-3.8). HIV treatment optimism-skepticism scores moderated the relationship: for GBM engaging in high-risk sexual behavior, higher HIV treatment optimism-skepticism scores increased perceived HIV risk. Promoting awareness around advances related to HIV prevention and treatment is important for appropriate risk assessment and for increased engagement in prevention interventions.
RESUMEN: Evaluamos la asociación entre el comportamiento sexual y la percepción de riesgo entre los participantes VIH negativos y si el optimismo sobre el tratamiento del VIH moderó esta asociación. Definimos comportamiento sexual de alto riesgo en los últimos seis meses como cualquier sexo anal sin condón con una pareja casual con un estado de VIH desconocido donde ninguno utilizó profilaxis previa a la exposición o con una pareja que vive con el VIH y que tiene una carga viral detectable/desconocida. Se evaluó el optimismo sobre el tratamiento del VIH mediante una escala de 12 ítems. Los modelos de regresión logística ajustados examinaron las asociaciones con la percepción del riesgo ("Riesgo no percibido" vs. "Riesgo percibido"). De 1961 participantes, 155 (17,0%), 62 (12,4%), 128 (17,2%) de los participantes en Montreal, Toronto y Vancouver, informaron comportamiento sexual de alto riesgo. El comportamiento sexual de alto riesgo se mostró asociado con riesgo percibido. El optimismo sobre el tratamiento modero la asociación. Promover la conciencia sobre los avances relacionados con la prevención y el tratamiento del VIH es importante para una evaluación adecuada de los riesgos y una mayor participación en las intervenciones de prevención.

ABSTRACT Objective: to analyze the distinct features, incongruencies, and harmony between the features of Canadian-Brazilian community health nursing as well their practices. Method: ethnographic research conducted in primary healthcare clinics (city of João Pessoa, Brazil). Data collection unfolded from July to September 2018 and included direct, unstructured participant observation of collective social and professional-clientele interactions, with a structured personal digital log and reports of the researcher's observations, as well as social immersion in community settings. The fieldwork log was thematically analyzed to build the meaning of the comparative nursing practice. Results: analysis of observations' reports identified challenges and opportunities to promote sustainable changes and create a supportive environment. Nurses' competencies to promote health are in consonance with conceptual, political, and ethical sounding perspectives. Among the distinctive practices observed was that in Brazil, the prescribing practice has been well-established because legally the registered nurses are allowed to prescribe within the primary healthcare programs. In Canada, registered nurses have been granted authority to do so, upon receipt of specific training and under certain scope of advanced practice. Thematic analysis revealed uniqueness of the grasped information, incongruence between community health nursing practices and harmony between contextual practices of Brazil-Canada community health nursing composed the empirical evidence. Conclusions: this research uncovered the compatibility between Canadian and Brazilian practice as well as intricate features of Brazilian community health nurses. Unquestionably, the evidence sums up to the consolidation of the well-established Brazil-Canada cooperation in the field of primary health care. This evidence addresses the political perspective of cooperation for global health.

Método: estudio etnográfico realizado en centros de atención primaria (ciudad de João Pessoa, Brasil). La recolección de datos se desarrolló de julio a septiembre de 2018 e incluyó la observación participante directa y no estructurada de las interacciones sociales colectivas y profesional-clientela, con un registro digital personal estructurado e informes de las observaciones del investigador, así como la inmersión social en entornos comunitarios. El registro de trabajo de campo se analizó temáticamente para construir el significado de la práctica de enfermería comparada. Resultados: el análisis de los informes de observaciones identificó desafíos y oportunidades para promover cambios sostenibles y crear un entorno de apoyo. Las competencias de los enfermeros para promover la salud están en consonancia con las perspectivas conceptuales, políticas y éticas. Entre las prácticas distintivas observadas, la práctica de prescripción ha sido bien establecida en Brasil porque legalmente las enfermeras están autorizadas a prescribir dentro de los programas de atención primaria de salud. En Canadá, a las enfermeras se les ha otorgado autoridad para hacerlo al recibir capacitación específica y bajo cierto alcance de práctica avanzada. El análisis temático reveló singularidad de la información captada, incongruencia entre las prácticas de enfermería en salud comunitaria y armonía entre las prácticas contextuales de enfermería en salud comunitaria Brasil-Canadá que compusieron la evidencia empírica. Conclusiones: esta investigación demostró que existe compatibilidad entre las prácticas canadiense y brasileña, así como las características de la enfermería comunitaria brasileña. Incuestionablemente, la evidencia resume la consolidación de la cooperación bien establecida entre Brasil y Canadá en el campo de la salud primaria. Esta evidencia aborda la perspectiva política de la cooperación para la salud global.

RESUMEN
Abstract Objectives: to describe the identification of fetal death during pregnancy in Brazilian and Canadian women. Methods: clinical-qualitative study with women who experienced the outcome of fetal death in their pregnancies, living in Maringá (Brazil) and participating in the Center d'intervention familiale (Canada). Data collection was performed through a semi-structured interview with the question: How did you find out about your baby's death? Readings were performed and the relevant aspects were categorized into themes according to the places where the death was confirmed. Results: in both countries, the main causes of death were the same, related to complications in pregnancy and childbirth, and health problems of the pregnant woman or fetus. Brazilian women had a higher frequency of deaths in the third trimester and Canadian women experienceda majority of deaths in the second trimester. The stillbirthswere found in different places, times and moments categorized at prenatal routine consultation, emergency care, expected death from congenital malformations of poor prognosis and labor. Conclusions: the determination of fetal death during pregnancy was due to possible intrinsic intercurrences of the pregnancy period. Based on the women's experiences, it was possible to demonstrate the clinical practice of identifying fetal death according to the cultural scenario. Continuous studies on prenatal care for women who had stillbirths are necessary for early detection of pathological conditions and appropriate interventions.
Resumo Objetivos: descrever a identificação do óbito fetal durante a gestação em brasileiras e canadenses. Métodos: estudo clínico-qualitativo com mulheres que vivenciaram o desfecho do óbito fetal nas suas gestações, residentes em Maringá (Brasil) e participantes do Centre d'Intervention Familiale (Canadá). A coleta de dados foi realizada por meio de entrevista semidirigida com a pergunta: Como ficou sabendo da morte do seu bebê? Foram realizadas leituras e os aspectos relevantes foram categorizados em temas conforme os locais da confirmação do óbito. Resultados: nos dois países, as principais causas dos óbitos foram relacionadas às complicações na gravidez e parto, problemas de saúde da gestante ou do feto. As brasileiras com frequência maior dos óbitos no terceiro trimestre e as canadenses, no segundo trimestre. As categorias foram identificadas nos consultórios na rotina pré-natal, nos serviços de emergência, e nos serviços de imagem, ao detectar o óbito esperado nos casos de malformações congênitas de prognóstico ruim. Conclusão: a determinação óbito fetal durante a gestação foi em razão das possíveis intercorrências intrínsecas do período gravídico. A partir das experiências das mulheres, foi possível mostrar a prática clínica da identificação do óbito fetal de acordo com o cenário cultural. Contínuos estudos, sobre a assistência pré-natal das mulheres que tiveram óbito fetal, são necessários para detecção precoce das condições patológicas e intervenções adequadas.

Increased life expectancy and high costs of medicines and medical care have led to the use of herbal products. However, these items may contain toxic compounds that have an impact on public health. We will focus on the regulatory aspects and differences of these products marketed in the North American region (USA-Mexico-Canada) from government websites and selected literature. Mexico has an ancestral tradition of using plants for the treatment, improvement, and maintenance of human health as compared with Canada and the USA Currently, the use of herbal products in this region has a regulatory framework. The legal framework in these three countries is related to their history, idiosyncrasies, socio-economic and cultural aspects. Therefore, there are different public policies for herbal products consumed in the region. Mexico has a more specific classification of these products. In Canada, all herbal products are classified as natural health products and the safety and efficacy must be scientifically proven. In the USA, the development of botanical drugs is very recent. In particular, both herbal products classified as food supplements in Mexico and dietary supplements in the USA may have risks in both safety and efficacy.

During the 2021 mass protests in Colombia, and while international calls for the Colombian government to respect human rights were intensifying, Canada's position remained somewhat ambiguous. Part of Canada's ambiguity can be explained by a simplistic characterization of Colombia as a "weak state." This article assesses Canada's bilateral relationship by historizing the development of Colombia's governance in the key overlapping sectors of security, human rights, and natural resources. From extensive fieldwork, we distinguish two competing rationalities based on the articulation of the notions of "conflict" and "dissent" with the notion of the "rule of law." We believe that Canada's bilateral relation with Colombia in the last decades has overlooked the contradictions that exist between democratizing rationalities and antipolitical rationalities. As a result, Canada's foreign policy has been based on an overly simplistic conception of the relationship between development, security, and the rule of law.
RESUMEN
Chronic diseases are a major health problem worldwide, especially in lower-income jurisdictions. Considering this scenario, the World Health Organization has recently established, as a research priority, preventive interventions for populations from lower-income countries, such as the middle-income country of Brazil. The purpose of this article is to describe the components of a pan-Canadian lifestyle program adapted to Brazilians and to report its health and fitness outcomes. A 12-week program called ACCELERATION was translated and culturally adapted to Brazilians. A quasi-randomized controlled trial was designed, consisting of weekly emails and educational videos addressing risk factors for chronic disease. Health and fitness measures included body composition, cardiovascular variables, aerobic fitness, and muscular strength. The Brazilian experimental group showed maintenance in heart rate, blood pressure, and VO2max values while presenting an improvement of 3.3% in body fat percentage (p = 0.040, d = -0.325) and 5.1% in muscular strength (p = 0.039, d = 0.328). Overall, these results were similar to the Canadian intervention. Based on these findings, the Brazilian version of the program has the potential to contribute to the fight against chronic diseases in Brazil.
RESUMEN
BACKGROUND: The COVID-19 pandemic has challenged health services and governments in Canada and around the world. Our research aims to evaluate the effect of domestic and international air travel patterns on the COVID-19 pandemic in Canadian provinces and territories. METHODS: Air travel data were obtained through licensed access to the 'BlueDot Intelligence Platform', BlueDot Inc. Daily provincial and territorial COVID-19 cases for Canada and global figures, including mortality, cases recovered and population data were downloaded from public datasets. The effects of domestic and international air travel and passenger volume on the number of local and non-local infected people in each Canadian province and territory were evaluated with a semi-Markov model. Provinces and territories are grouped into large (>100 000 confirmed COVID-19 cases and >1 000 000 inhabitants) and small jurisdictions (≤100 000 confirmed COVID-19 cases and ≤1 000 000 inhabitants). RESULTS: Our results show a clear decline in passenger volumes from March 2020 due to public health policies, interventions and other measures taken to limit or control the spread of COVID-19. As the measures were eased, some provinces and territories saw small increases in passenger volumes, although travel remained below pre-pandemic levels. During the early phase of disease introduction, the burden of illness is determined by the connectivity of jurisdictions. In provinces with a larger population and greater connectivity, the burden of illness is driven by case importation, although local transmission rapidly replaces imported cases as the most important driver of increasing new infections. In smaller jurisdictions, a steep increase in cases is seen after importation, leading to outbreaks within the community. CONCLUSIONS: Historical travel volumes, combined with data on an emerging infection, are useful to understand the behaviour of an infectious agent in regions of Canada with different connectivity and population size. Historical travel information is important for public health planning and pandemic resource allocation.

INTRODUCTION: Introducing legislation that restricts companies from exposing children to marketing of unhealthy food and beverage products is both politically and technically difficult. To advance the literature on the technical design of food marketing legislation, and to support governments around the world with legislative development, we aimed to describe the legislative approach from three governments. METHODS: A multiple case study methodology was adopted to describe how three governments approached designing comprehensive food marketing legislation (Chile, Canada and the United Kingdom). A conceptual framework outlining best practice design principles guided our methodological approach to examine how each country designed the technical aspects of their regulatory response, including the regulatory form adopted, the substantive content of the laws, and the implementation and governance mechanisms used. Data from documentary evidence and 15 semi-structured key informant interviews were collected and synthesised using a directed content analysis. RESULTS: All three countries varied in their legislative design and were therefore considered of variable strength regarding the legislative elements used to protect children from unhealthy food marketing. When compared against the conceptual framework, some elements of best practice design were present, particularly relating to the governance of legislative design and implementation, but the scope of each law (or proposed laws) had limitations. These included: the exclusion of brand marketing; not protecting children up to age 18; focusing solely on child-directed marketing instead of all marketing that children are likely to be exposed to; and not allocating sufficient resources to effectively monitor and enforce the laws. The United Kingdom's approach to legislation is the most comprehensive and more likely to meet its regulatory objectives. CONCLUSIONS: Our synthesis and analysis of the technical elements of food marketing laws can support governments around the world as they develop their own food marketing restrictions. An analysis of the three approaches illustrates an evolution in the design of food marketing laws over time, as well as the design strengths offered by a legislative approach. Opportunities remain for strengthening legislative responses to protect children from unhealthy food marketing practices.

BACKGROUND: Although marriage is associated with favourable reproductive outcomes among adult women, it is not known whether the marriage advantage applies to girls (< 18 years). The contribution of girl child marriage (< 18 years) to perinatal health is understudied in the Americas. METHODS: National singleton birth registrations were used to estimate the prevalence of girl child marriage among mothers in Brazil (2011-2018, N = 23,117,661), Ecuador (2014-2018, N = 1,519,168), the USA (2014-2018, N = 18,618,283) and Canada (2008-2018, N = 3,907,610). The joint associations between marital status and maternal age groups (< 18, 18-19 and 20-24 years) with preterm birth (< 37 weeks), small-for-gestational age (SGA < 10 percentile) and repeat birth were assessed with logistic regression. RESULTS: The proportion of births to < 18-year-old mothers was 9.9% in Ecuador, 8.9% in Brazil, 1.5% in the United States and 0.9% in Canada, and marriage prevalence among < 18-year-old mothers was 3.0%, 4.8%, 3.7% and 1.7%, respectively. In fully-adjusted models, marriage was associated with lower odds of preterm birth and SGA among 20-24-year-old mothers in the four countries. Compared to unmarried 20-24-year-old women, married and unmarried < 18-year-old girls had higher odds of preterm birth in the four countries, and slightly higher odds of SGA in Brazil and Ecuador but not in the USA and Canada. In comparisons within age groups, the odds of repeat birth among < 18-year-old married mothers exceeded that of their unmarried counterparts in Ecuador [AOR: 1.99, 95%CI: 1.82, 2.18], the USA [AOR: 2.96, 95%CI: 2.79, 3.14], and Canada [AOR: 2.17, 95%CI: 1.67, 2.82], although minimally in Brazil [AOR: 1.09, 95%CI: 1.07, 1.11]. CONCLUSIONS: The prevalence of births to < 18-year-old mothers varies considerably in the Americas. Girl child marriage was differentially associated with perinatal health indicators across countries, suggesting context-specific mechanisms.

Scientific diasporas from developing countries represent an opportunity to strengthen international collaborations. These collaborations build upon the desire of members of the diasporas to establish scientific, academic, technological, and cultural exchange networks with the communities in their country of origin. While Mexico has a significant number of scientists residing abroad, particularly in North America, and most of them are committed to aid in the country's development, institutional coordination has not harnessed its benefits. In this work, we present an analysis of initiatives carried out by Mexican scientists, members of the diaspora, studying or working in the United States of America and Canada. The study is based on a set of interviews with members of this diaspora. We asked scientists about the conditions that enabled or obstructed their initiatives back in Mexico, and we discussed the role of these factors for capacity building. We also provide general recommendations to enhance contributions to the advancement of science in the country.

Babesia and Theileria are apicomplexan parasites that cause established and emerging diseases in humans, domestic and wild animals. These protozoans are transmitted by Ixodid ticks causing babesiosis or theileriosis, both characterized by fever, hemolytic anemia, jaundice, and splenomegaly. In North America (NA), the most common species affecting humans is B. microti, which is distributed in the Northeastern and Upper Midwestern United States (US), where the tick vector Ixodes scapularis is established. In livestock, B. bovis and B. bigemina are the most important pathogens causing bovine babesiosis in tropical regions of Mexico. Despite efforts toward eradication of their tick vector, Rhipicephalus microplus, B. bovis and B. bigemina present a constant threat of being reintroduced into the southern US and represent a continuous concern for the US cattle industry. Occasional outbreaks of T. equi, and T. orientalis have occurred in horses and cattle, respectively, in the US, with significant economic implications for livestock including quarantine, production loss, and euthanasia of infected animals. In addition, a new species, T. haneyi, has been recently discovered in horses from the Mexico-US border. Domestic dogs are hosts to at least four species of Babesia in NA that may result in clinical disease that ranges from subclinical to acute, severe anemia. Herein we review the pathogenesis, diagnosis, and epidemiology of the most important diseases caused by Babesia and Theileria to humans, domestic and wild animals in Canada, the US, and Mexico.
RESUMEN
OBJECTIVES: To examine characteristics of children referred for obesity management based on referral frequency, child- and referrer-related variables associated with re-referral, and determine whether re-referral increased treatment initiation. STUDY DESIGN: This population-level, retrospective analysis included all 2- to 17-year-olds referred for obesity management to 1 of 3 multidisciplinary clinics in Alberta, Canada between April 2013 and December 2017. Children were dichotomized based on referral frequency, specifically once only or more than once (re-referred). Data were retrieved from standardized referral forms and patient registries. Analyses included logistic regression and generalized estimating equations models. RESULT: We analyzed data from 2745 children (47.2% female; mean age: 11.4 years; mean body mass index z score: 3.03) and 2705 physicians (60.2% female; 65.6% pediatricians). Overall, 300 (10.2%) children were re-referred with most (n = 276; 92.0%) being referred twice. Children were less likely to be re-referred if they were referred by a family physician (vs pediatrician) (aOR 0.62; 95% CI 0.46-0.84; P = .0018) or scheduled a clinic appointment following their index referral (aOR: 0.29; 95% CI 0.21-0.4; P < .001). Treatment initiation was higher in children who were referred once only (42.1%) vs their re-referred peers (18.0%; P < .0001); however, for children who were re-referred, they were more likely to initiate treatment following their second referral (aOR 2.3; 95% CI 1.22-4.31; P = .01). This improvement was not sustained on subsequent referrals (aOR 0.44; 95% CI 0.17-1.12; P = .08). CONCLUSIONS: Few children were re-referred for pediatric obesity management; however, for those children who were re-referred, being re-referred once only increased the likelihood of treatment initiation.

INTRODUCTION: Injection drug use initiation is commonly facilitated by other people who inject drugs (PWID). We investigated how the gender of PWID influences their risk of providing initiation assistance to others across two distinct geo-cultural settings. METHODS: Data were drawn from two prospective cohorts in Tijuana, Mexico and Vancouver, Canada which conducted semi-annual interviews within the PReventing Injecting by Modifying Existing Responses (PRIMER) study. Participants consisted of PWID who had reported never providing injection initiation assistance at baseline. We then conducted site-specific discrete-time survival analyses assessing the relationship between gender and other relevant covariates (e.g. age and past 6-month sex work) on the risk of the first reported instance of providing initiation assistance. RESULTS: Of 1988 PWID (Tijuana: n = 596; Vancouver: n = 1392), 256 (43%) and 511 (36.7%) participants were women, and 42 (1.7%) and 78 (1.6%) reported recent injection initiation assistance across a median of three and two follow-up visits, respectively. Women had a lower risk of providing injection initiation assistance for the first time in Tijuana (adjusted hazard ratio = 0.52, 95% confidence interval 0.27-0.99), but not in Vancouver. Gendered pathways, like sex work, were associated with providing initiation assistance for the first time in Vancouver (adjusted hazard ratio = 1.97, 95% confidence interval 1.08-3.61). DISCUSSION AND CONCLUSIONS: Women in Tijuana, but not Vancouver, were less likely to provide first-time initiation assistance among PWID. These results can inform gender- and site-specific prevention efforts aimed at reducing transitions into drug injecting across geographic contexts.

Purpose: To identify key attributes of Canadian clinical registered dietitian (RD) jobs associated with high rates of turnover.Methods: Managers of clinical RDs in Canada were eligible to complete a survey on the topic of turnover in clinical RD positions. Specifically, key details were sought regarding positions with the highest and lowest turnover in each manager's portfolio.Results: High turnover (HT) positions turned over an average of 4.0 times in a 5-year period in contrast to 0.3 times in low turnover (LT) positions. Resignation was the top reason for turnover in both HT and LT positions. HT and LT positions were of analogous full-time equivalent, had comparable caseloads, and served clients/patients with similar diagnoses including diabetes and neurological conditions.Conclusions: There is significant variation in the frequency of turnover across positions in clinical dietetics in Canada. What differentiates HT positions from LT positions remains unclear. More research is required to guide managers seeking to balance turnover and preclude uneven nutrition care quality across units and programs.

STUDY BACKGROUND: The aging population in Canada has been increasing steadily over the past 40 years, however, there is limited information about the meaning of aging well amongst older Brazilian women in Canada. METHODS: A Heideggerian interpretive phenomenology study was conducted to understand the meaning of aging well amongst older Brazilian women in the post-migration context living in the Greater Toronto Area (GTA) in Ontario, Canada. RESULTS: Eight older Brazilian women residing in the GTA were recruited through purposive and snowball sampling and participated in individual face-to-face interviews. Through data analysis and the incorporation of Heidegger's four existentials of human existence, the themes that emerged were (a) Embracing being part of a mosaic, (b) Aging with grace, (c) Chasing your dreams and (d) Being a bridge and not a fence. The overarching theme was: Finding the silver lining: Aging well. CONCLUSION: This study informs nursing practice, research and policy development to advance the health of older immigrant adults in Canada.

Tobacco combustion exposure worsens rheumatoid arthritis (RA). Non-combustible tobacco devices, as heat-not-burn tobacco (HNBT), are emerging as harm reduction to smokers by releasing nicotine and lower combustible tobacco products. Nevertheless, HNBT toxicity remains unclear. Hence, here we investigated the impacts of the tobacco combustible product (cigarette smoke; CS) or HNBT vapor exposures on antigen-induced arthritis (AIA) in C57BL/6 mice. Animals were exposed to airflow, HNBT vapor, or CS during 1 h/twice a day, under the Health Canada Intense (HCI) smoking regime, between days 14 to 20 after the first immunization. At day 21, 16 h after the last exposures, mice were i.a. challenged and the AIA effects were evaluated 24 h later. CS- or HNBT-exposed mice presented equivalent blood nicotine levels. CS exposure worsened articular symptoms, pulmonary inflammation, and expression of lung metallothioneins. Nevertheless, CS or HNBT exposures reduced lymphoid organs' cellularity, splenocyte proliferation and IL-2 secretion. Additional in vitro CS or HNBT exposures confirmed the harmful effects on splenocytes, which were partially mediated by the activation of nicotine/α7nAchR pathway. Associated, data demonstrate the toxic mechanisms of CS or HNBT inhalation at HCI regime on RA, and highlight that further investigations are fundamental to assure the toxicity of emerging tobacco products on the immune system during specific challenges.

ABSTRACT As the leading risk for death, population control of increased blood pressure represents a major challenge for all countries of the Americas. In the early 1990's, Canada had a hypertension control rate of 13%. The control rate increased to 68% in 2010, accompanied by a sharp decline in cardiovascular disease. The unprecedented improvement in hypertension control started around the year 2000 when a comprehensive program to implement annually updated hypertension treatment recommendations started. The program included a comprehensive monitoring system for hypertension control. After 2011, there was a marked decrease in emphasis on implementation and evaluation and the hypertension control rate declined, driven by a reduction in control in women from 69% to 49%. A coalition of health and scientific organizations formed in 2011 with a priority to develop advocacy positions for dietary policies to prevent and control hypertension. By 2015, the positions were adopted by most federal political parties, but implementation has been slow. This manuscript reviews key success factors and learnings. Some key success factors included having broad representation on the program steering committee, multidisciplinary engagement with substantive primary care involvement, unbiased up to date credible recommendations, development and active adaptation of education resources based on field experience, extensive implementation of primary care resources, annual review of the program and hypertension indicators and developing and emphasizing the few interventions important for hypertension control. Learnings included the need for having strong national and provincial government engagement and support, and retaining primary care organizations and clinicians in the implementation and evaluation.
RESUMEN La hipertensión arterial representa el principal riesgo de muerte; controlarla a nivel de la población constituye un desafío importante para todos los países de la Región de las Américas. A principios de la década de 1990, Canadá presentaba una tasa de control de la hipertensión del 13%. La tasa de control aumentó al 68% en el 2010, lo que vino acompañado por una disminución importante de las enfermedades cardiovasculares. Esta mejora sin precedentes en el control de la hipertensión empezó alrededor del año 2000 cuando se inició un programa integral para aplicar las recomendaciones sobre el tratamiento de la hipertensión, actualizadas anualmente. El programa incluyó un sistema de monitoreo integral para el control de la hipertensión. Después del 2011, hubo una marcada disminución del énfasis en la implementación y la evaluación, y la tasa de control de la hipertensión disminuyó, impulsada por una reducción en el control en las mujeres, que pasó del 69% al 49%. En el 2011, se formó una coalición de organizaciones científicas y de salud con la prioridad de elaborar una campaña de defensa y promoción de las políticas alimentarias para prevenir y controlar la hipertensión. Para el año 2015, esta postura fue adoptada por la mayoría de los partidos políticos federales, aunque la implementación ha sido lenta. En este artículo se revisan los factores clave de éxito y las lecciones aprendidas. Algunos factores clave de éxito fueron tener una amplia representación en el comité directivo del programa; el compromiso multidisciplinario con la participación sustantiva del sector de la atención primaria; unas recomendaciones creíbles, imparciales y actualizadas; el desarrollo y la adaptación activa de recursos educativos basados en la experiencia en el terreno; la amplia implementación de los recursos de la atención primaria; la revisión anual del programa y de los indicadores de hipertensión; y el desarrollo y el énfasis en unas pocas intervenciones importantes para el control de la hipertensión. Entre las lecciones aprendidas se encontró la necesidad de contar con un fuerte compromiso y apoyo del gobierno nacional y provincial, y de mantener a las organizaciones de atención primaria y al personal médico en la implementación y la evaluación.
RESUMO O controle populacional da hipertensão arterial - o maior fator de risco de morte - representa um grande desafio para todos os países das Américas. No início da década de 1990, o Canadá tinha uma taxa de controle de hipertensão de 13%. Esse índice aumentou para 68% em 2010, acompanhado por um declínio acentuado das doenças cardiovasculares. A melhoria sem precedentes no controle da hipertensão começou por volta do ano 2000, quando teve início um programa abrangente para implementar recomendações de tratamento de hipertensão atualizadas anualmente. O programa incluía um sistema integral de monitoramento do controle da hipertensão. Após 2011, houve uma acentuada redução da ênfase na implementação e avaliação, e a taxa de controle de hipertensão caiu, principalmente às custas de uma redução deste controle em mulheres (de 69% para 49%). Uma coalizão de organizações científicas e de saúde formou-se em 2011 com a prioridade de desenvolver posições de defesa de políticas alimentares para prevenir e controlar a hipertensão. Até 2015, essas posições haviam sido adotadas pela maioria dos partidos políticos federais, mas a implementação tem sido lenta. Este manuscrito examina fatores-chave de sucesso e aprendizados. Alguns fatores-chave de sucesso incluíram uma ampla representatividade no comitê diretor do programa, engajamento multidisciplinar (com envolvimento significativo da atenção primária), recomendações imparciais e confiáveis, elaboração e adaptação ativa de recursos didáticos com base na experiência de campo, ampla implementação dos recursos da atenção primária, revisão anual do programa e dos indicadores de hipertensão e desenvolvimento e ênfase das poucas intervenções realmente importantes para o controle da hipertensão. As lições aprendidas incluíram a necessidade de ter forte envolvimento e apoio dos governos nacional e subnacionais e manter organizações e médicos da atenção primária engajados na implementação e avaliação.
RESUMEN
In light of new evidence on the prevention of chronic diseases and the elevated rates of overweight and obesity in Brazil and Canada, this critical review aims to interpret and synthesize current aspects regarding dietary and physical activity initiatives in both countries and make future recommendations. The pioneering work presented in the last Brazilian dietary guidelines has been called a model that can be applied globally, given its conceptualization of healthy eating that translates easily to practical guidance. The new Canadian Food Guide has incorporated similar aspects, also putting the country as a leader in dietary guidance. With these new recommendations, citizens in both Brazil and Canada have access to impactful evidence-informed nutritional guidelines. Both documents propose eating patterns that focus not only on health benefits, such as chronic disease prevention, but also incorporate well-being concerning cultural, economic, sociodemographic, biological, and ecological dimensions. A similar approach is required for physical activity to allow individuals to have attainable health and life goals and thereby fully enjoy their lives, regardless of geographical location, health status, and socioeconomic condition, a concept recently described as physical activity security. The wholistic dietary guidelines from both countries represent a change in paradigm in public health. Likewise, national evidence-based policies are warranted to reduce disparities in physical activity, allowing healthier and more active lifestyles for everyone.
