ABSTRACT OBJECTIVE: To explore the associations between current mental health symptoms and social disparities in university students. METHODS: We recruited participants from nine public universities in Brazil, from August to November 2022, using online advertisements and in-person lectures. All participants completed an online survey containing social (sex, race/color, gender identity, sexual orientation, and income) and mental health assessments. The Jeopardy index was composed of social variables. The index considered zero points for subjects with less oppressive experienced characteristics (men, White, cisgender, heterosexual, higher income) and one point for the opposite characteristics. We defined six clusters according to Jeopardy Index results: 0, 1, 2, 3, 4, and 5 points, with the greatest number of points representing the most disadvantaged group. The mental health symptoms were assessed on two levels. First by the “DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure – Adult,” and second by the “Patient Health Questionnaire-9,” and the “Generalized Anxiety Disorder Questionnaire-7.” Adjusted Odds Ratio (OR) analyses was performed for age and educational level. RESULTS: 748 participants were allocated into the six Jeopardy clusters: 0 (n = 46; 6.1%), 1 (n = 112; 15.0%), 2 (n = 163; 21.8%), 3 (n = 218; 29.1%), 4 (n = 171; 22.9%), and 5 (n = 38; 5.1%). It was observed a high prevalence of anxiety (42.5%) and depression (51.0%), however, the less privileged group (5) had a higher risk of having severe symptoms of anxiety (OR = 6.21; 1.51–25.58; p < 0.01) and depression (OR = 8.60; 2.15–34.43; p < 0.01), compared against the most privileged group. CONCLUSION: Although anxiety and depressive symptoms were highly prevalent for all participants, these disorders are not equally distributed in this population and the intersectionality between social factors plays an important role in contributing to these differences.

Resumo O objetivo é analisar as associações da vitimização e perpetração do bullying com sintomas depressivos e qualidade de vida relacionada à saúde (QVRS) em uma amostra de adolescentes brasileiros do ensino médio. Os adolescentes (n=852, 50,2% do sexo feminino, idade média: 16,4 anos) responderam a um questionário sobre sintomas depressivos elaborado a partir da Escala de Depressão do Center for Epidemiologic Studies. A QVRS foi medida através do Índice Kidscreen-10, e a informação relacionada com o bullying foi extraída de duas questões diferentes (vítimas e agressores). Foram utilizados modelos de regressão logística multinível. Os adolescentes vítimas de bullying apresentaram níveis mais altos de sintomas depressivos e uma percepção mais baixa de QVRS do que aqueles que não eram vítimas. Por outro lado, foi encontrada uma relação inversa entre os perpetradores de bullying em comparação com aqueles que não eram perpetradores. O impacto na saúde dos adolescentes varia de acordo com o seu papel em situações de bullying.

Resumen El objetivo es analizar las asociaciones de victimización y perpetración de bullying con síntomas depresivos y calidad de vida relacionada con la salud (CVRS) en una muestra de adolescentes brasileños de secundaria. Los adolescentes (n=852, 50,2% mujeres, edad media: 16,4 años) respondieron a un cuestionario sobre síntomas depresivos extraído de la Escala de Depresión del Centro de Estudios Epidemiológicos. La CVRS se midió mediante el índice Kidscreen-10 y la información relacionada con el acoso se extrajo de dos preguntas diferentes (víctimas y agresores). Se utilizaron modelos de regresión logística multinivel. Los adolescentes que fueron víctimas de bullying tuvieron mayores niveles de síntomas depresivos y una menor percepción de CVRS que aquellos que no fueron víctimas. Por otro lado, se encontró una relación inversa entre los perpetradores de acoso escolar respecto a aquellos que no lo fueron. El impacto en la salud de los adolescentes varía según su papel en situaciones de bullying.

Abstract The aim is to analyze the associations of bullying victimization and perpetration with depressive symptoms and health-related quality of life (HRQoL) in a sample of Brazilian high school adolescents. Adolescents (n=852, 50.2% female, mean age: 16.4 years) answered a questionnaire about depressive symptoms drawn from the Center for Epidemiologic Studies Depression Scale. HRQoL was measured using the Kidscreen-10 Index, and bullying-related information was extracted from two different questions (victims and perpetrators). Multilevel logistic regression models were used. Adolescent victims of bullying had higher levels of depressive symptoms and a lower perception of HRQoL than those who were not victims. On the other hand, an inverse relationship was found for perpetrators of bullying compared to those who were not perpetrators. Adolescents’ health-related impacts varied according to their role in bullying situations.

Abstract Objectives To assess alcohol use and perceived change in alcohol consumption (before and during the pandemic) in Brazilians during the COVID-19 pandemic, their correlates, and their associations with depressive, anxiety and co-occurring depressive and anxiety symptoms (D&A). Methods This is a cross-sectional study comprising 992 individuals in self-isolation. A self-report questionnaire was used to assess whether participants were drinking during self-isolation and whether they changed their drinking behavior (drinking less, more, or no change) from before to during the pandemic. D&A symptoms were assessed using the Beck Depression and Anxiety Inventories (BDI and BAI). Results A total of 68.5% of participants reported alcohol consumption during the pandemic, and 22.7% of these reported increased alcohol use. Smoking was positively associated with alcohol consumption during the pandemic. Alcohol consumption was associated with anxiety (OR = 1.40, 95%CI 1.06-1.85, p < 0.01) and D&A (OR = 1.38, 95%CI 1.02-1.87, p = 0.033) symptoms. Conclusions Drinking during self-isolation was prevalent and was associated with risk factors for alcohol use disorders. The long-term effects of high drinking rates and increased consumption should be proactively monitored and assessed. pandemic COVID19 COVID 19 COVID-1 correlates cooccurring co occurring D&A. DA .

ABSTRACT Objectives: The objectives of the present study were to assess sedentary behavior and physical activity levels before and during the COVID-19 pandemic in healthy individuals and in those with self-reported diagnosis of anxiety and/or depression, and also identify facilitators and barriers to physical activity in these populations. Methods: This is a cross-sectional survey based on a self-report questionnaire applied during the COVID-19 pandemic period. Results: In the total sample (N = 1,285) the prevalence of sedentary behavior (>8 hours/day) increased by 25% during social isolation. Social isolation increased sedentary time and decreased physical activity levels in healthy individuals and in those with self-reported diagnosis of anxiety and/or depression. In both groups, the most prevalent facilitators were supervised physical activity (before the pandemic) and activities and equipment to practice at home (during the pandemic). The most prevalent barriers were the lack of time to perform physical activities (before the pandemic) and inaccessible or distance places to practice (during the pandemic). Conclusion: The COVID-19 pandemic is related to an increased sedentary behavior and reduced physical activity levels. Significant changes in perceived barriers and facilitators to exercise were observed during the social isolation period.

RESUMO Objetivos: Os objetivos do presente estudo foram avaliar o comportamento sedentário e os níveis de atividade física antes e durante da pandemia de COVID-19 em indivíduos saudáveis e com diagnóstico autorreportado de ansiedade e/ou depressão e identificar os facilitadores e barreiras para a prática de atividade física nessas populações. Métodos: Trata-se de uma pesquisa de corte transversal baseada em um questionário de autorrelato aplicado durante o período de pandemia da COVID-19. Resultados: Na amostra total (N = 1.285), a prevalência de comportamento sedentário (>8 horas/dia) aumentou em 25% durante o isolamento social. O isolamento social aumentou o tempo sedentário e diminuiu os níveis de atividade física em indivíduos saudáveis, com ansiedade e/ou depressão autorreportada. Nos dois grupos, os facilitadores mais prevalentes foram a atividade física supervisionada (antes da pandemia) e as atividades e equipamentos para a prática em casa (durante a pandemia). As barreiras mais prevalentes foram a falta de tempo para realizar atividades físicas (antes da pandemia) e os locais inacessíveis ou distantes para a prática (durante a pandemia). Conclusão: A pandemia de COVID-19 está relacionada a aumento do comportamento sedentário e redução dos níveis de atividade física. Mudanças significativas nas barreiras percebidas e facilitadores ao exercício foram observadas durante o período de isolamento social.

ABSTRACT Objective: Substance misuse can lead to several consequences for physical and mental health. Physical exercise is an important ally to pharmacological and psychotherapeutic treatment for substance use. However, the literature is still scarce regarding long-term interventions. Thus, this study aims to describe the acceptability and effects of combined physical training intervention (aerobic and strength). Methods: This study comprises an n-of-1 clinical trial that was performed with a 64-year-old male individual with alcohol use disorder. The treatment lasted 12 weeks and evaluated the association of multidisciplinary interventions on quality of life, depressive symptoms, cognitive impairment, and anxiety. Results: The participant improved general quality of life (12.5%), no alterations were found for depressive symptoms, there was an improvement in cognition (20%), as well a reduction in the trait (16.2%) and state (14.7%) anxiety symptoms of the participant. Conclusions: These findings allude to the importance of non-drug therapeutic resources such as structured physical exercise, associated with other offers in the treatment of alcohol use disorder.

RESUMO Objetivo: O uso de substâncias psicoativas pode levar a diversas consequências à saúde física e mental. O exercício físico é um importante aliado ao tratamento farmacológico e psicoterápico para o uso de substâncias. No entanto, a literatura ainda é escassa em relação às intervenções de longa duração. Dessa forma, este estudo objetiva descrever a aceitabilidade e os efeitos de uma intervenção de treinamento físico combinado (aeróbico e força). Métodos: Este estudo compreende um n-of-1 clinical trial que foi realizado com um indivíduo do sexo masculino, de 64 anos de idade, com transtorno por uso de álcool. O tratamento teve a duração de 12 semanas e avaliou a associação de intervenções multiprofissionais sobre a qualidade de vida, sintomas depressivos, comprometimento cognitivo e ansiedade. Resultados: O participante melhorou a qualidade de vida geral (12,5%), não foram encontradas alterações para sintomas depressivos, houve melhora na cognição (20%), bem como redução nos sintomas de ansiedade traço (16,2%) e estado (14,7%) do participante. Conclusões: Esses achados aludem à importância de recursos terapêuticos não medicamentosos como o exercício físico estruturado, associados às demais ofertas no tratamento para o transtorno por uso de álcool.

Objective: To assess differences in blood inflammatory cytokines between people with alcohol use disorder (AUD) and healthy controls (HC). Methods: Searches were performed from inception through April 14, 2021. Meta-analyses with random-effects models were used to calculate the standardized mean difference ([SMD], 95%CI), and potential sources of heterogeneity were explored trough meta-regressions and subgroup analysis. Results: The meta-analysis included 23 studies on the following 14 cytokines: tumor necrosis factor (TNF)-α, IL-1, IL-1RA, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-13, IL15, interferon (IFN)-γ and sCD14. There were significantly higher concentrations of IL-6 (n=462 AUD and 408 HC; SMD = 0.523; 95%CI 0.136-0.909; p = 0.008) in AUD than HC. No significant differences were found in the other 13 cytokines. Conclusion: We found that IL-6 levels were significantly higher in individuals with AUD than HC and that other cytokines were not altered. This can be explained by the small number of studies, their methodological heterogeneity, and confounding factors (active use, abstinence, quantity, and physical or psychiatric illnesses, for example). Despite a great deal of evidence about alcohol and inflammatory diseases, studies assessing the role of neuroimmune signaling in the development and severity of AUD are still lacking.

Objective: Conduct a systematic review and meta-analysis to evaluate levels of anger among substance users compared to non-user controls and to analyze the possible association between anger and psychoactive substance use (PSU). Methods: The procedures of this review followed the Meta-Analyzes of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Four electronic databases (MEDLINE, EMBASE, BIREME, PsycINFO) were searched. Results: Twelve studies were included in the meta-analysis; 10 used the State-Trait Anger Expression Inventory (STAXI) anger trait subscale and two used the Buss-Perry-Aggression Questionnaire (BPAQ) anger subscale. The sample included 2,294 users of psychoactive substances and 2,143 non-users, all male. The mean difference in anger scale scores between users and non-users was 2.151 (95%CI 1.166-3.134, p ≤ 0.00, inconsistency index [I2] = 98.83) standard deviations. Age and abstinence duration did not moderate the difference in anger between substance users and non-users. Conclusion: Users of psychoactive substances had elevated anger scores compared to non-users, which represents a high risk of relapse. It is suggested that PSU treatment programs include intensive anger management modules, focusing on factors such as dealing with daily stressors, family conflicts, frustrations, and problems.

RESUMO Objetivos. Caracterizar como a atividade física e o comportamento sedentário têm sido medidos em pesquisas nacionais de saúde em países sul-americanos. Métodos. Foi realizada uma busca extensa de pesquisas nacionais de saúde de todos os 12 países sul-americanos em sites de saúde e órgãos nacionais de estatística, e pelo contato com pesquisadores e formuladores de políticas. Foram usados os seguintes critérios de elegibilidade para selecionar as pesquisas: conduzida em um país sul-americano; que tenha usado uma amostra nacionalmente representativa ≥ 18 anos; coordenada pelo setor público, privado ou público-privado; e que tenha avaliado a atividade física e/ou o comportamento sedentário. Os dados extraídos eram sobre informações gerais das pesquisas, detalhes específicos sobre a avaliação da atividade física e do comportamento sedentário e questões adicionais relacionadas ao comportamento na atividade. Resultados. Ao todo, 36 pesquisas foram incluídas, duas das quais foram conduzidas em vários países. Todas as pesquisas avaliaram a atividade física e 27 avaliaram o comportamento sedentário. A maioria das pesquisas (23/36; 64%) baseou-se em questionários internacionais previamente validados e 13 (57%) delas se desviaram das ferramentas de referência, introduzindo mudanças e adaptações. O comportamento sedentário foi avaliado principalmente por meio de perguntas sobre tempo de tela e/ou tempo diário sentado nos mesmos questionários sobre atividade física. Nenhuma pesquisa utilizou medições realizadas por dispositivos para gerar dados sobre esses comportamentos. Conclusões. As diferenças entre os instrumentos usados e as modificações limitam a comparabilidade dos dados entre os países, o que destaca a importância de padronizar a avaliação na América do Sul para as seções de atividade física e comportamento sedentário em pesquisas nacionais, com o objetivo mais amplo de contribuir para o estabelecimento de uma estratégia padronizada para a vigilância da atividade física e do comportamento sedentário na América do Sul.

RESUMEN Objetivos. Describir cómo se han medido la actividad física y el sedentarismo en las encuestas nacionales de salud en los países de América del Sur. Métodos. Se llevó a cabo una extensa búsqueda de encuestas nacionales de salud de los doce países sudamericanos en sitios web de salud, oficinas nacionales de estadística y mediante el contacto con investigadores y responsables de formular políticas. Para escoger las encuestas se emplearon los siguientes criterios de selección: realizada en un país sudamericano; muestra representativa a nivel nacional de ≥ 18 años; coordinada por el sector público, el sector privado o mixto público-privado; y evaluación de la actividad física o el sedentarismo. Se extrajeron datos como información general de las encuestas, detalles específicos de la evaluación de la actividad física y el sedentarismo, y otras preguntas relacionadas con la actividad física. Resultados. En total, se incluyeron 36 encuestas, dos de las cuales se realizaron en varios países. Todas las encuestas evaluaron la actividad física; 27, el sedentarismo. La mayoría de las encuestas (23/36; 64%) se basaron en cuestionarios internacionales anteriormente validados, de los cuales 13 (57%) se desviaron de las herramientas de referencia al tener cambios y adaptaciones. El sedentarismo se evaluó principalmente en los mismos cuestionarios de actividad física mediante preguntas sobre el tiempo invertido delante de pantallas o el tiempo diario sentado. Ninguna encuesta aplicó medidas basadas en dispositivos para obtener datos sobre estos comportamientos. Conclusiones. Las diferencias entre los instrumentos empleados y las modificaciones limitan la comparabilidad de los datos en todos los países. Esto pone de relieve la importancia de estandarizar la evaluación en América del Sur de las secciones dedicadas a la actividad física y al sedentarismo en las encuestas nacionales, con el objetivo general de contribuir a la creación de una estrategia estandarizada para la vigilancia de la actividad física y el sedentarismo en América del Sur.

ABSTRACT Objectives. To characterize how physical activity and sedentary behavior have been measured in national health surveys in South American countries. Methods. An extensive search was made for national health surveys from all 12 South American countries through health websites, national statistical offices, and contact with researchers and policy-makers. The following eligibility criteria were used to select surveys: conducted in a South American country; used a nationally representative sample ≥ 18 years; coordinated by the public, private or mixed private–public sector; and assessed physical activity and/or sedentary behavior. Data were extracted on general information about the surveys, specific details about the physical activity and sedentary behavior assessment, and additional questions related to activity behavior. Results. In total, 36 surveys were included, two of which were multicountry surveys; all surveys assessed physical activity and 27 assessed sedentary behavior. Most surveys (23/36; 64%) were based on previously validated international questionnaires, but 13 (57%) of these deviated from the reference tools, introducing changes and adaptations. Sedentary behavior was assessed mostly through questions on screen time and/or daily sitting time in the same physical activity questionnaires. No survey used device-based measures to generate data on these behaviors. Conclusions. Differences between instruments used and modifications limit the comparability of data across countries. This highlights the importance of standardizing assessment within South America for physical activity and sedentary behavior sections in national surveys, with the broader aim of contributing to establishing a standardized strategy for the surveillance of physical activity and sedentary behavior in South America.

Objective: Our aim was to analyze the association between sugar-sweetened beverage consumption and depressive symptoms, as well as the extent to which TV viewing and physical activity moderate this association. Methods: We used cross-sectional data from the 2013 Brazilian National Survey (Pesquisa Nacional de Saúde) of 59,402 adults (33,482 women, mean age = 42.9 years, 95%CI 42.7-43.2 years). Depressive symptoms (Patient Health Questionnaire-9), physical activity, TV viewing, and sugar-sweetened beverage consumption, as well as potential confounders (chronological age, ethnicity, consumption of candy/sweets and fruit, multimorbidity, education, and employment status) were self-reported. Poisson regression models were used for association analyses. Results: The consumption of 16 or more glasses/week of sugar-sweetened beverages was associated with higher levels of severe depressive symptoms among women compared to no consumption (prevalence ratio [PR] 1.71 [95%CI 1.38-2.11]). Consistent interactions were observed between 1-5 glasses and TV viewing (PR 2.09 [95%CI 1.06-4.12]) and between 11-15 glasses and TV viewing (PR 2.90 [95%CI 1.29-6.50]) among men compared to no consumption, given that the co-occurrence of sugar-sweetened beverage consumption and elevated TV viewing was associated with higher odds of severe depressive symptoms. Sugar-sweetened beverage consumption did not interact with physical activity, only presenting an independent association. Conclusion: Sugar-sweetened beverage consumption was independently associated with severe depressive symptoms among women and interacted with TV viewing, but not with physical activity among men.

Abstract Introduction Physical activity, conceptualized as any bodily movement that results in energy expenditure, and its structured form, exercise, play an important role in public health, preventing and treating a wide range of physical conditions, including metabolic and cardiovascular diseases and obesity. Objective This article aims to provide a brief overview and summary of the evidence on: 1) the preventive effects of physical activity on a wide range of mental disorders; 2) the role of physical activity in promoting the physical health of people with mental disorders; 3) the role of exercise as a strategy to manage mental health symptoms in a range of mental disorders; and 4) the challenges and barriers faced when implementing exercise in clinical practice. Methods This was a narrative review. Results Compelling evidence has demonstrated that physical activity and exercise can also prevent common mental disorders, such as depression and anxiety disorders, and have multiple beneficial effects on the physical and mental health of people with a wide range of mental disorders. This body of evidence has been incorporated in national and international guidelines over the last decades, which have recommended the inclusion of physical activity and exercise as therapeutic approaches for mental disorders, mainly for depression and schizophrenia. Nonetheless, implementation into clinical practice has been slow, probably due to barriers associated both with patients and mental health professionals. Conclusion Increases in physical activity levels in populations are likely to reduce the mental health burden. Exercise interventions should be incorporated to the routine care of people with mental disorders due its multiple benefits on physical and mental health outcomes. A multidisciplinary approach is needed to overcome patients barriers and enhance adherence and benefits.

Abstract Introduction Individuals with major depressive disorder (MDD) face more barriers to engagement in sports and exercise interventions. Evaluating clinical and demographic factors associated with adherence to sports and exercise among MDD outpatients could support development of new options and strategies to increase their participation. Methods In a cross-sectional study, 268 depressed outpatients were evaluated (83.51% females; mean age = 50.74 [standard deviation {SD} = 10.39]). Sports and exercise participation were assessed using a question about participation frequency during the previous month. Clinical and demographic factors were evaluated. Linear regression was used to identify predictors of participation in sports and exercise. Results MDD patients with mild symptoms of depression (odds ratio [OR] = 2.42; 95% confidence interval [95%CI] 1.00, 5.88; p = 0.04) and patients with mild to moderate symptoms (OR = 3.96; 95%CI 1.41, 11.15; p = 0.009) were more likely to engage regularly in sports and exercise than patients with more severe depression. Moreover, smoking (OR = 0.23; 95%CI 0.67, 0.80; p = 0.007) and being divorced (OR = 0.22; 95%CI 0.57, 0.86; p = 0.03) were associated with lower rates of engagement in sports and exercise. Conclusion Our findings indicate a significant association between clinical and demographic factors and participation in sports and exercise among MDD outpatients.

Objective: The aim of this study was to understand the knowledge, beliefs, barriers, and behaviors of mental health professionals about physical activity and exercise for people with mental illness. Methods: The Portuguese version of The Exercise in Mental Illness Questionnaire was used to assess knowledge, beliefs, barriers, and behaviors about exercise prescription for people with mental illness in a sample of 73 mental health professionals (68.5% women, mean age = 37.0 years) from 10 Psychosocial Care Units (Centros de Atenção Psicossocial) in Porto Alegre and Canoas, state of Rio Grande do Sul, Brazil. Results: Most of respondents had received no formal training in exercise prescription. Exercise ranked fifth as the most important treatment, and most of the sample never or occasionally prescribed exercise. The most frequently reported barriers were lack of training in physical activity and exercise prescription and social stigma related to mental illness. Professionals who themselves met recommended physical activity levels found fewer barriers to prescribing physical activity and did so with greater frequency. Conclusion: Exercise is underrated and underused as a treatment. It is necessary to include physical activity and exercise training in mental health curricula. Physically active professionals are more likely to prescribe exercise and are less likely to encounter barriers to doing so. Interventions to increase physical activity levels among mental health professionals are necessary to decrease barriers to and increase the prescription of physical activity and exercise for mental health patients.

Objective: To evaluate the associations of moderate to vigorous physical activity (MVPA), vigorous physical activity (VPA), moderate physical activity (MPA), and sedentary behavior (SB) with depressive, anxiety, and co-occurring depressive and anxiety symptoms (D&amp;A) during the COVID-19 pandemic in Brazil.Methods: Cross-sectional online survey in self-isolating people. Self-reported MVPA, VPA, MPA, and SB (exposures), and depressive and anxiety symptoms (Beck Depression and Anxiety Inventories [BDI and BAI]) were collected. Associations of MVPA, VPA, MPA, and SB with prevalent depressive (BDI&gt;9), anxiety (BAI&gt;7), and D&amp;A (BDI&gt;9+BAI&gt;7) symptoms were investigated using logistic regressions, presented as odds ratio (OR) and 95% confidence interval (95%CI). Linear regressions were performed testing associations with symptom severity. Models were adjusted for confounding factors. Results: Participants (n=937, females=72.3%) performing ≥30min/day MVPA or ≥15min/day VPA had lower odds of prevalent depressive (ORMVPA=0.71, 95%CI=0.53-0.96; ORVPA=0.60, 95%CI=0.43-0.82), anxiety (ORMVPA=0.71, 95%CI=0.54-0.96; ORVPA=0.70, 95%CI=0.51-0.96), and co-occurring D&amp;A symptoms (ORMVPA=0.71, 95%CI=0.52-0.96; ORVPA=0.59, 95%CI=0.41-0.83). People spending ≥10h/day sedentary were more likely to have depressive symptoms (OR=1.39,95%CI=1.02-1.90). Each hour spent sedentary corresponded to 0.22 (95%CI=0.10-0.33) points and 0.16 (95%CI=0.02-0.31) points higher on the BDI and BAI, respectively.Conclusion: Higher MVPA and VPA levels are associated with lower odds of depressive, anxiety and D&amp;A symptoms. Higher SB is associated with higher odds of depressive symptoms.

Resumo Introdução: A depressão maior (DM) é uma doença associada ao estresse crônico que pode apresentar um desequilíbrio nos níveis de cortisol, podendo ser recuperado com a remissão dos sintomas. O exercício tem sido utilizado como uma ferramenta para promover mudanças nos níveis de cortisol em indivíduos saudáveis. No entanto, não se sabe se o exercício produz os mesmos resultados em indivíduos com DM. Objetivo: Revisar evidências de alterações dos níveis de cortisol após o exercício em indivíduos com DM. Métodos: Foi realizada busca nas bases de dados PubMed, SciELO, LILACS, ISI Web of Knowledge, Scopus e PsycInfo. Procedeu-se a metanálise com o cálculo do tamanho do efeito da diferença de média padronizada. Foi utilizado o software Stata v.11.0. Resultados: Foram obtidos na busca 463 estudos. Após o procedimento de seleção, cinco artigos com sete análises foram incluídos. O tipo de exercício, frequência de treinamento, tipo de medida do cortisol e tipo de grupo controle foram analisados como subgrupos. Houve uma redução dos níveis de cortisol no grupo de exercício. Além disso, a análise de sensibilidade e análises de subgrupos revelaram um efeito do tipo (exercício aeróbico) e da frequência (cinco vezes por semana) de exercício na redução dos níveis de cortisol. No entanto, esses resultados devem ser interpretados com cautela, devido ao pequeno número de estudos e uma heterogeneidade substancial entre eles. Conclusão: O exercício promove redução dos níveis de cortisol em indivíduos com DM. No entanto, esse achado pode ser influenciado pelo tipo de exercício, medida do cortisol e frequência semanal.

Abstract Introduction: Major depressive disorder (MDD) is a prevalent medical illness that is associated with chronic stress. Patients with MDD can show an imbalance in cortisol levels, which can be restored with the remission of symptoms. Physical exercise training has been used as a tool to promote changes in cortisol levels in healthy individuals. However, it is unknown if exercise can produce the same results in individuals with MDD. Objective: To review evidence of cortisol changes after exercise training in individuals with MDD. Methods: We conducted a search on PubMed, SciELO, LILACS, ISI Web of Knowledge, Scopus, and PsycInfo databases. Random effects meta-analysis was performed and standardized mean difference (SMD) effect size was calculated. Analyses of forest and funnel plots was conducted using Stata v.11.0 software. Results: At first, 463 studies were obtained in the search. After completion of the selection procedure, five articles with seven analyses were included. Type of exercise, frequency of training, cortisol measurement, and type of control group were analyzed. There was a reduction of cortisol levels in the exercise group (SMD = −0.65, 95%CI 1.30-0.01). Moreover, sensitivity analysis and subgroup analyses revealed an effect of type (aerobic exercise) and frequency (five times per week) of exercise on reduction of cortisol levels. However, these results should be interpreted cautiously due to the small number of studies and a substantial heterogeneity among them. Conclusion: Physical exercise promotes a reduction in cortisol levels in individuals with MDD. However, this finding can be influenced by type of exercise, weekly frequency, and type of cortisol measurement.
