Tendencia de consejerías en actividad física y enfermedades cardiometabólicas en el Maule, Chile: estudio previo a pandemia por COVID-19 entre 2012 y 2019 / Trend in Physical Activity Counseling and Cardiometabolic Diseases in Maule, Chile: COVID-19 Pre-Pandemic Study between 2012 and 2019

BACKGROUND: Physical activity (PA) practice reduces the adverse effects of COVID-19. PA counseling promotes healthy lifestyles and prevents cardiometabolic diseases. AIM: To assess the trend in cases of PA counseling and the cardiometabolic disease between 2012 and 2019 (before COVID-19) in a southern Chilean region. MATERIAL AND METHODS: Records of Maule Region Health Service for 731.163 men, and 829.097 women aged < 10 to ≥ 65 years were analyzed. The average annual percentage change (AAPC) during the study period and the annual percentage change (APC) during intermediate periods, were calculated. RESULTS: There was a significant decrease in PA counseling in women in the study period (AAPC: −13.6%). In the 2012-2017 period a significant decrease in counseling for total, men and women were observed (APC: −18.1, −16.5 and −19.1%, respectively). Obesity increased significantly in total, men and women in the 2012-2019 period (AAPC: 10.1, 8.5 and 10.7%, respectively). The same trend was observed for hypertension (AAPC: 8.1, 8.5 and 7.6% respectively) and elevated blood glucose (AAPC: 10, 11.5 and 9.6%, respectively). CONCLUSIONS: In the study period PA counseling decreased along with an increase in obesity, hypertension and high blood glucose. Increasing PA counseling is a mainstay in the prevention of cardiometabolic diseases and probably to prevent contagion and complement the treatment of COVID-19.

Barreras y facilitadores para la formulación de políticas públicas que regulan los ambientes alimentarios obesogénicos: revisión de la literatura / Barriers and facilitators to policymaking public policies that regulate obesogenic food environments: review of the literature

INTRODUCCIÓN: Los ambientes alimentarios determinan en gran medida el comportamiento alimentario de la población, por lo que se asocian a la epidemia de obesidad. Es responsabilidad de los Estados formular e implementar políticas para intervenir los ambientes alimentarios obesogénicos. El éxito de las políticas dependerá de factores que actúan como barreras o facilitadores. OBJETIVO: Identificar las barreras y facilitadores que se presentan al formular e implementar políticas públicas que aborden los ambientes alimentarios obesogénicos. MATERIAL Y MÉTODO: Estudio secundario en base a revisión narrativa. La identificación, tamizaje y selección de los artículos publicados se guio por el diagrama PRISMA. Para la identificación se recurrió a las bases de datos electrónicas PubMed, Scielo, Scopus y Web of Science (WOS), ingresando campos de búsqueda y palabras clave. En el tamizaje se eliminaron los duplicados y se aplicaron criterios de inclusión. La calidad metodológica de los estudios elegibles se evaluó con el protocolo CASPe. RESULTADOS: Se revisaron estudios cualitativos que usaron entrevistas a actores claves. Las barreras identificadas para el proceso de formulación de políticas de ambientes alimentarios obesogénicos son el impacto económico negativo, falta de evidencia científica sobre la efectividad de las políticas, influencia de la industria alimentaria, debilidades de coordinación y cooperación técnica. Los facilitadores identificados son el compromiso político de los Estados con las agencias internacionales, enfoque de trabajo conjunto con la industria alimentaria y el apoyo académico. CONCLUSIÓN: La formulación de políticas para intervenir ambientes alimentarios obesogénicos está especialmente limitada por la industria alimentaria. Es relevante generar evidencia científica del impacto que, las regulaciones implementadas, han tenido en los factores económicos y sobre la salud de la población. La colaboración entre gobiernos e industria alimentaria, podría derivar políticas que, además de impactar positivamente la salud de la población, sean una oportunidad para el sector privado y la generación de empleo.

INTRODUCTION: Food environments largely determine the eating behavior of the population, which is why they are associated with the obesity epidemic. It is the responsibility of States to formulate and implement policies to intervene in obesogenic food environments. The success of the policies will depend on factors that act as barriers or facilitators. OBJECTIVE: To identify the barriers and facilitators for the formulation and implementation of public policies that address obesogenic food environments. MATERIAL AND METHOD: Secondary study based on narrative review. The identification, screening and selection of published articles was guided by the PRISMA diagram. For the identification, the electronic databases PubMed, Scielo, Scopus and Web of Science (WOS) were used, entering search fields and keywords. In the screening, duplicates were eliminated and inclusion criteria were applied. The methodological quality of eligible studies was assessed using the CASPe protocol. RESULTS: Qualitative studies that used interviews with key actors were reviewed. The barriers identified for the process of formulating policies on obesogenic food environments are the negative economic impact, lack of scientific evidence on the effectiveness of policies, influence of the food industry, weaknesses in coordination and technical cooperation. The identified facilitators are the political commitment of the States with international agencies, a joint work approach with the food industry and academic support. CONCLUSION: Policymaking to intervene in obesogenic food environments is especially limited by the food industry. It is relevant to generate scientific evidence of the impact that the implemented regulations have had on economic factors and on the health of the population. Collaboration between governments and the food industry could derive policies that, in addition to having a positive impact on the health of the population, would mean an opportunity for the private sector and the generation of employment.

Relação entre o perfil de adesão e as barreiras para a permanência no programa de extensão "yoga: awaken one" / Relationship between the membership profile and the barriers to stay in the "yoga: awaken one" extension program

Objetivo: Investigar a relação entre o perfil de adesão e barreiras percebidas por estudantes universitários para permanência no Programa de Extensão "Yoga: Awaken ONE". Métodos: Foram realizados dois cortes transversais com universitários da Universidade Federal do Recôncavo da Bahia. O primeiro foi composto por 16 indivíduos e investigou o perfil demográfico, socioeconômico, antropométrico, da aptidão física e da qualidade de vida dos universitários que ingressaram no Programa de Extensão. O segundo visou identificar as barreiras para permanência de 13 estudantes (dentre os 16 iniciais) que haviam se afastado do Programa após quatro meses do início. Resultados: Houve predominância de indivíduos do sexo feminino, dos cursos de graduação em Educação Física e Pedagogia e da classe socioeconômica C. A maioria dos participantes estava com indicadores adequados de gordura corporal. Observou-se grande proporção de indivíduos com indicadores baixos de flexibilidade e força muscular. Para a qualidade de vida, a menor mediana foi observada para o domínio meio ambiente e a maior para o domínio relações sociais. As principais barreiras percebidas para a prática de yoga pelos universitários foram "jornada de estudos extensa" e "jornada de trabalho extensa". Observou-se correlação do perfil sociodemográfico, indicadores de obesidade, variáveis hemodinâmicas, flexibilidade, força muscular e qualidade de vida com barreiras percebidas para permanência no Programa de Extensão universitária "Yoga: Awaken ONE". Conclusões: Estes achados sugerem que o perfil do público universitário pode ser determinante para a permanência ou evasão de programas de promoção de exercícios físicos e precisa ser considerado em propostas de programas de extensão universitária.

Objective: Investigate the relationship between the member adherence profile and barriers perceived by university students to remain in the "Yoga: Awaken ONE" Extension Program. Methods: Two cross-sections were carried out with university students from the Federal University of Recôncavo da Bahia. The first was composed of 16 individuals and investigated the demographic, socioeconomic, anthropometric, physical fitness, and quality of life profile of university students joining the Extension Program. The second aimed at identifying the barriers to remain in the program faced by 13 students (out of the initial 16) who had withdrawn from the Program four months after the beginning. Results: There was a predominance of female individuals, from undergraduate courses in Physical Education and Pedagogy, and from the C socioeconomic class. Most participants had adequate body fat indexes. There was a large proportion of individuals with low flexibility and muscle strength. For quality of life, the lowest median was observed for the environment domain, while the highest could be noted for the social relationship domain. The main barriers perceived for the practice of yoga by university students were "long study hours" and "long work hours". There was a correlation between sociodemographic profile, obesity indicators, hemodynamic variables, flexibility, muscle strength, and QOL with the perceived barriers to stay in the "Yoga: Awaken ONE" university extension program. Conclusions: These findings suggest that the profile of the university audience can be a determinant for the permanence or dropout of programs that promote physical exercise and therefore, it should be taken into consideration in proposals for university extension programs.

Management of overweight and obesity in children and adolescents by nurses: a mixed-method study / Manejo do sobrepeso e obesidade em crianças e adolescentes por enfermeiras: estudo de métodos mistos / Control del sobrepeso y la obesidad en niños y adolescentes por enfermeras: un estudio de métodos mixtos

Abstract Objective: to analyze the management of overweight and obesity in children and adolescents by nurses of the Family Health Strategy. Method: this is a study of convergent parallel mixed methods, developed in Health Centers of a municipality in northeastern Brazil. In the quantitative stage, data were collected from a questionnaire applied to 98 nurses and analyzed by descriptive statistics. For the qualitative stage, semi-structured interviews were conducted with seven nurses, interpreted by inductive thematic analysis. The quantitative and qualitative results were integrated and presented by a joint display. Results: most nurses rarely checked waist circumference (77.6%), dyslipidemia (55.7%), blood glucose (42.3%), and neither evaluated blood pressure (75.3%). In the qualitative results, we identified that there are nurses who did not classify body mass index according to sex and age. As for medical tests, the requests were mainly related to the routine of childcare. Guidance on physical activity and diet were given in a basic way or attributed to other professionals, and referrals to other services or professionals were not followed up. Conclusion: it is imperative to train nurses for the management of overweight and obesity in primary care for children and adolescents, with a view to quality of care for the prevention of comorbidities.

Epidemiological research progress on the relationship between children's dietary patterns and health / 中华预防医学杂志

As food preferences and eating habits form early in life, the development of healthy eating habits in early childhood is a way to prevent diet-related diseases. The dietary pattern approach examines the effect of an overall diet on health outcomes, instead of individual foods or nutrients, thereby presenting a comprehensive evaluation of children's dietary intake. This article reviews the current literature to summarize the main methods for assessing dietary patterns and explore relationships between children's dietary patterns and obesity, puberty onset, cardiovascular diseases, and neurodevelopment. The purpose of this review is to provide evidence-based support for reducing the risk of diet-related diseases in children and recommendations for future research directions.

Current status and progress of precision nutritional weight management guided by single nucleotide polymorphism / 中华预防医学杂志

The incidence of obesity in our country is increasing year by year. Diet and lifestyle interventions are the most commonly used weight loss measures, but their intervention effects are affected by individual genetics, environment and other factors. Genome-wide association analysis has found many SNPs related to weight loss, and explored the interaction between these loci and diet, intestinal flora and other environmental factors. This article summarizes the study of single nucleotide polymorphisms, the analysis of gene-environment interactions related to diet interventions for weight loss, and the multi-loci analysis and prediction models such as genetic risk scores and machine learning modeling in weight loss, which provides reference for the further application and development of the precise nutrition in medical weight loss.

Principales Estrategias de Intervención Nutricional realizadas en Chile en el decenio 2010-2020: avances y desafíos / Main Nutritional Intervention Strategies carried out in Chile in the 2010-2020 decade: progress and challenges

La alta prevalencia de obesidad en Chile, y su tendencia al aumento, constituye un problema de Salud Pública por su asociación con enfermedades crónicas no transmisibles. Durante la década 2010-2020, el estado de Chile implementó estrategias de intervención nutricional dirigidas a mantener o disminuir la prevalencia de obesidad. Regulaciones como la ley 20.606 sobre composición nutricional de los alimentos y su publicidad para modificar los entornos alimentarios, sistema elige vivir sano como modelo de gestión intersectorial constituido por políticas, planes y programas elaborados y ejecutados por distintos organismos del Estado, destinados a contribuir a generar hábitos y estilos de vida saludable y a prevenir y disminuir los factores y conductas de riesgo asociados a las enfermedades no transmisibles. A pesar de todos los esfuerzos, las encuestas poblacionales han demostrado que la obesidad continúa en aumento a lo largo del ciclo vital, por lo que es necesario fortalecer las estrategias existentes, pero con enfoque de determinantes sociales y de salud en todas las políticas, y a su vez mejorar los sistemas de evaluación de las estrategias implementadas en la población, midiendo su impacto además de su ejecución.

The high prevalence of obesity in Chile, and its increasing trend, constitutes a Public Health problem due to its association with chronic non-communicable diseases. During the 2010-2020 decade, the state of Chile implemented nutritional intervention strategies aimed at maintaining or reducing the prevalence of obesity. Regulations such as Law 20.606 on the nutritional composition of food and its advertising to modify food environments, Sistema chooses to live healthy System "EVS" Choose Healthy lifestyles as an intersectoral management model made up of policies, plans and programs prepared and executed by different State agencies, intended to contribute to healthy habits and lifestyles and to prevent and reduce risk factors and behaviors associated with non-communicable diseases. Despite all efforts, population surveys have shown that obesity continues to increase throughout the life cycle, which is why it is necessary to strengthen existing strategies, but with a focus on social and health determinants in all policies, since in turn, improve the evaluation systems of the strategies implemented in the population, measuring their impact, in addition to their implementation.

Thirty five percent of participants reported having lack of time, 11% reported problems with internet connectivity and 3.9%, personal or work problems. Conclusions: This is the first experience with MOOC in health and nutrition to prevent obesity in Chile. Considering the good results and positive evaluation of these courses, we estimate that they are an important tool to prevent obesity and chronic diseases in Chile, Latin America and other regions of the world.

Reference Equation for the Six-Minute Walk Test in Brazilian Patients with Obesity

Abstract Background: Obesity has repercussions on functional capacity (FC). The six-minute walk test (6MWT) is a useful tool for assessing submaximal FC, and the distance reached at 6 minutes of walking (D6MW) is a relevant prognostic marker. Objective: This paper aims to establish a reference equation for the distance predicted in 6MWT in obese Brazilian subjects. Methods: This study included 460 patients (306 women), with a body mass index (BMI) > 30 kg/m2, 71% (328) of whom presented a grade III obesity (BMI ≥ 40 Kg/m²) and were evaluated with 6MWT. Heart rate, blood pressure, oxygen saturation and Borg scale perception of effort were recorded before and after the 6MWT. For statistical analysis, Kolmogorov-Smirnov tests, an unpaired T-Test, Pearson's correlation, and multiple linear regression were used, together with a significance level set at p<0.05. Results: Gender, age, and BMI were significantly correlated with D6MW and were identified by multiple linear regression as the best predictors of the D6MW. Together, they explain 48.7% of the D6MW variance for obese Brazilian subjects. Based on these findings, an equation was proposed - D6MW = 930.138 + (27.130 x Genderfemales = 0; males = 1) − (5.550 x BMI kg/m2) − (4.442 x Age years). When the average of the D6MW obtained with the above equation was compared to the average calculated with the equations described in medical literature for healthy and obese individuals, the latter tended to overestimate the D6MW. Conclusion: The proposed reference equation exhibited better assessment of FC in obese Brazilian patients, providing proper subsidies for the follow up ofinterventions in this population..

Diabetes mellitus, obesidad, cáncer y la necesidad de nuevas estrategias de prevención / Diabetes Mellitus, Obesity, Cancer and the Need for New Prevention Strategies

Durante los últimos años ha cobrado especial importancia la relación entre la diabetes mellitus (DM) y el cáncer, la cual ha sido reconocida por las guías de la American Diabetes Association1 y referida recientemente en el 9no Atlas de la Federación Internacional de Diabetes (IDF; por sus siglas en inglés).2 La asociación está basada en la evidencia científica y en el hecho de que ambas enfermedades comparten factores de riesgo comunes como obesidad, sobrepeso y dieta poco saludable, junto con situaciones características de la diabetes, como la hiperinsulinemia, hiperglucemia e inflamación. Por su parte, el sobrepeso y la obesidad tienen un efecto sobre el cáncer, de manera independiente y asociada a la DM. En el año 2012, el 5,7 por ciento de diferentes tipos cáncer fueron atribuibles a los efectos combinados de la diabetes mellitus tipo 1 y diabetes mellitus tipo 2 (DMT2) y el elevado índice de masa corporal (IMC) (≥25 kg/m2), ascendiendo esta cifra a nivel mundial a más de 800 000 nuevos casos de cáncer ese año.3) Asimismo, el sobrepeso y la obesidad en la adolescencia se asocian con el riesgo de desarrollar cáncer en etapas posteriores de la vida, con un aumento de la mortalidad por esta causa.4 En el reporte de 2018 del Cancer Research UK,5 se estimó que el alto IMC causa más cáncer de intestino...(AU)

Obesidad, intervención escolar, actividad física y estilos de vida saludable en niños españoles / Obesity, School Intervention; Physical Activity and Healthy Lifestyles in Spanish Children

Introducción: El sobrepeso y la obesidad en la infancia y la adolescencia se han incrementado a nivel mundial durante las últimas décadas. Este hecho se asocia, principalmente, con la falta de actividad física, hábitos de vida y comportamientos alimenticios poco saludables. Objetivo: Analizar la efectividad de diferentes estudios de intervención escolar llevados a cabo en España para prevenir y tratar la obesidad en niños y niñas. Métodos: Se realizó una estrategia de búsqueda electrónica utilizando las bases de datos PubMed, Medline y SPORTdiscus y los términos school-based intervention, Spain, healthy lifestyle, obesity prevention, physical activity y nutrition childhood obesity y children obesity. Se identificaron 124 artículos y solo 11 cumplieron los criterios de inclusión. Conclusiones: Las intervenciones realizadas por el entorno escolar no fueron eficaces o significativas para cambiar los indicadores antropométricos de los niños, niñas y adolescentes españoles. Sin embargo, las intervenciones escolares unidas a la implicación familiar, pueden ser eficaces para modificar cambios en los hábitos nutricionales, nivel de actividad física y hábitos de vida saludable en la etapa infantojuvenil, ya que son los principales determinantes de obesidad en la infancia. Por último, la consolidación de un adecuado estilo de vida en etapas tempranas puede prevenir la obesidad y sobrepeso en la adultez(AU)

Introduction: Overweight and obesity in childhood and adolescence have increased worldwide in recent decades. This fact is associated mainly with a lack of physical activity, unhealthy lifestyle habits and eating behaviors. Objective: To analyze the effectiveness of different school intervention studies carried out in Spain to prevent and treat obesity in boys and girls. Methods: An electronic search strategy was carried out using the PubMed, Medline and SPORTdiscus databases, under the terms school-based intervention, Spain, healthy lifestyle, obesity prevention, physical activity, nutrition, childhood obesity and children obesity. 124 articles were identified and only 11 met the inclusion criteria. Conclusions: The interventions carried out by school were not effective or significant to change the anthropometric indicators of Spanish children and adolescents. However, school interventions, together with family involvement, can be effective in modifying changes in nutritional habits, level of physical activity and healthy lifestyle habits in the infant-juvenile stage, since they are the main determinants of obesity in childhood. Finally, establishing an adequate lifestyle early can prevent obesity and overweight in adulthood(AU)

Prática de atividade física para controle de diabetes, hipertensão e obesidade da população adulta na Atenção Primária à Saúde / Practice of physical activity to control diabetes, hypertension and obesity in the adult population in Primary Health Care

Esta revisão rápida foi comissionada e subsidiada pelo Ministério da Saúde, no âmbito do projeto GEREB-010-FIO-20 e faz parte da Coleção "Rapid response for health promotion". Contexto: As Doenças Crônicas Não Transmissíveis (DCNT) estão entre as principais causas de mortalidade no mundo. Diabetes mellitus tipo 2 (DM2), hipertensão arterial sistêmica (HAS) e obesidade são considerados problemas de saúde pública com alta prevalência em países pobres. A atividade física pode ser um fator protetivo para DCNT, auxiliando na prevenção e tratamento das doenças e da incapacidade funcional, por meio da redução da adiposidade corporal e da pressão arterial, melhora do perfil lipídico e da sensibilidade à insulina, entre outros benefícios. Pergunta: Quais intervenções de atividade física são efetivas para controle de diabetes, hipertensão e de sobrepeso/obesidade na Atenção Primária à Saúde (APS)? Métodos: Oito bases da literatura eletrônica foram buscadas em maio de 2021 para identificar revisões sistemáticas (RS) sobre intervenções de atividade física para controle ou melhoria dos quadros de diabetes, hipertensão e sobrepeso/obesidade. Utilizando atalhos de revisão rápida para simplificar o processo, foram realizadas seleção e extração dos dados com posterior avaliação da qualidade das RS. Em seguida, os resultados foram reunidos em síntese narrativa conforme similaridade. Resultados: A busca retornou 633 referências únicas, que após seleção resultaram na inclusão de 6 revisões sistemáticas, todas de confiança criticamente baixa na avaliação da qualidade metodológica. A maioria dos estudos foi realizada na Ásia e América do Norte, com destaque para China e Estados Unidos. Uma revisão sistemática incluiu estudos realizados no Brasil. O protocolo desta revisão previa a inclusão de estudos realizados em serviços de atenção primária à saúde, porém durante o processo de seleção foi necessário ampliar os critérios de elegibilidade, pois não foram identificados estudos restritos a contextos de APS. Algumas RS também incluíram o grupo de comparadores envolvendo atividade física e voluntários saudáveis. Os resultados foram apresentados em três categorias conforme a condição analisada: hipertensão, diabetes mellitus 2 e as três condições combinadas (HAS, DM2 e obesidade). Os estudos envolveram as seguintes intervenções: prática de tai chi chuan; treino de resistência e/ou aeróbico; aeróbico, musculação e educação sobre estilo de vida; yoga; treino de hidroginástica, fortalecimento, alongamento e Baduanjin; uso de monitores de atividade (acelerômetros ou pedômetros) e exercício de resistência progressiva; pedômetro com atividade física. A maioria dos resultados mostrou efeitos positivos (pressão arterial média; controle efetivo da pressão arterial - PA; redução das pressões arteriais sistólica (PAS) e diastólica (PAD); melhora na medida da hemoglobina glicada; diminuição significativa do índice de massa corporal - IMC), indicando também incertezas quanto a alguns desfechos. Conclusão: As RS que avaliaram pacientes hipertensos indicam redução na PA com a prática de atividade física, porém a certeza da evidência foi baixa em uma delas. O uso de monitores de atividade não resultou em melhora nos indicadores de pacientes com DM2. Uma das RS indicou que exercícios de resistência melhoraram a medida da hemoglobina glicada, mas não apresentaram efeito na composição corporal de pacientes com DM2 e sobrepeso. Já o uso de pedômetros, em uma RS, foi associado à diminuição no IMC e na PAS em pacientes com comorbidades. Os estudos incluídos devem ser avaliados com cautela, pois apresentaram falhas metodológicas que comprometem a confiança em seus resultados.

This rapid review was commissioned and subsidized by the Ministry of Health, within the scope of the GEREB-010-FIO-20 project and is part of the "Rapid response for health promotion" Collection. Context: Chronic Noncommunicable Diseases (NCDs) are among the leading causes of mortality in the world. Type 2 diabetes mellitus (DM2), systemic arterial hypertension (SAH) and obesity are considered public health problems with high prevalence in poor countries. Physical activity can be a protective factor for NCDs, helping to prevent and treat diseases and functional disability, by reducing body adiposity and blood pressure, improving lipid profile and insulin sensitivity, among other benefits. Question: Which physical activity interventions are effective for controlling diabetes, hypertension and overweight/obesity in Primary Health Care (PHC)? Methods: Eight electronic literature databases were searched in May 2021 to identify systematic reviews (SR) on physical activity interventions to control or improve diabetes, hypertension and overweight/obesity. Using quick review shortcuts to simplify the process, data selection and extraction were performed with subsequent evaluation of the SR quality. Then, the results were gathered in narrative synthesis according to similarity. Results: The search returned 633 unique references, which after selection resulted in the inclusion of 6 systematic reviews, all with critically low confidence in the assessment of methodological quality. Most studies were carried out in Asia and North America, with emphasis on China and the United States. A systematic review included studies carried out in Brazil. The protocol of this review provided for the inclusion of studies carried out in primary health care services, but during the selection process it was necessary to expand the eligibility criteria, as no studies restricted to PHC contexts were identified. Some SRs also included the group of comparators involving physical activity and healthy volunteers. The results were presented in three categories according to the condition analyzed: hypertension, diabetes mellitus 2 and the three conditions combined (SAH, DM2 and obesity). The studies involved the following interventions: practice of tai chi chuan; resistance and/or aerobic training; aerobics, strength training and lifestyle education; yoga; water aerobics, strengthening, stretching and Baduanjin training; use of activity monitors (accelerometers or pedometers) and progressive resistance exercise; pedometer with physical activity. Most of the results showed positive effects (mean blood pressure; effective control of blood pressure - BP; reduction of systolic (SBP) and diastolic (DBP) blood pressures; improvement in the measurement of glycated hemoglobin; significant decrease in body mass index - BMI ), also indicating uncertainties regarding some outcomes. Conclusion: The SRs that evaluated hypertensive patients indicated a reduction in BP with the practice of physical activity, but the certainty of the evidence was low in one of them. The use of activity monitors did not result in an improvement in the indicators of patients with DM2. One of the RS indicated that resistance exercises improved the measurement of glycated hemoglobin, but had no effect on the body composition of patients with DM2 and overweight. The use of pedometers in an SR was associated with a decrease in BMI and SBP in patients with comorbidities. The included studies should be evaluated with caution, as they had methodological flaws that compromise confidence in their results.
