Resumo A pandemia de COVID-19 provocou alterações na vida, afetando hábitos e comportamentos e uma de suas consequências é aumento de peso. O objetivo foi avaliar a associação entre trabalho remoto e ganho de peso durante a pandemia de COVID-19 em duas cidades do sul do Brasil. Estudo transversal de base populacional realizado na região sul do Brasil. Os dados foram coletados face a face, em domicílios selecionados por amostragem censitária. O desfecho foi ganho de peso e a exposição foi trabalho remoto. Para verificar essa associação, utilizou-se Regressão de Poisson para calcular a razão de prevalência bruta e ajustada e seus intervalos de confiança de 95%, com nível de significância de 5%. Foram entrevistados 2.152 indivíduos. A prevalência de ganho de peso durante a pandemia foi de 38,4% (IC95% 36,1-40,7), sendo maior naqueles que trabalharam remotamente (47,0% vs 37,7, p=0,02). Indivíduos que trabalharam remotamente tiveram 23% mais chances de ganhar peso durante a pandemia comparados àqueles que não trabalharam remotamente (RP: 1,23; IC95% 1,02-1,49).

Abstract The COVID-19 pandemic caused changes in life, affecting habits and behaviors, and one of its consequences is an increase in weight. We aimed to evaluate the association between remote work and weight gain during the COVID-19 pandemic in two cities in southern Brazil. A population-based cross-sectional study carried out in the southern region of Brazil. Data were collected face-to-face, in households selected by census sampling. The outcome was weight gain, and the exposure was remote working. To verify this association, Poisson Regression was used to calculate the crude and adjusted prevalence ratio and its 95% confidence intervals, using 5% significance level. In total, 2,152 individuals were interviewed. The prevalence of weight gain during the pandemic was 38.4% (95%CI 36.1-40.7), being significantly higher in those who worked remotely (47.0% vs 37.7, p=0.02). Those individuals who worked remotely were 23% more likely to gain weight during the pandemic compared to those who did not work remotely (PR: 1.23; 95%CI 1.02-1.49). Health and education services may be encouraged to implement educational actions at the collective level, aimed at enlightening the population and preventing weight gain in periods of confinement.

ABSTRACT Objective To analyze the prevalence and factors associated with alcohol consumption among pregnant women. Methods This cross-sectional study examined pregnant women living in Brazilian capitals using information collected by the Noncommunicable Chronic Disease Risk Factor Surveillance System (Vigitel) between 2006 and 2021. This study calculated the prevalence of both excessive and any amount of alcohol consumption by pregnant women and their associations with sociodemographic variables. Multivariate analysis was performed with prevalence ratios based on Poisson crude and adjusted regressions; the threshold for statistical significance was set at p<0.05. Results The sample comprised 4,734 pregnant women. The prevalence of any amount of alcohol consumption was 11.5% (95%CI = 9.8-13.6), and that of excessive consumption was 3.0% (95%CI = 2.1-4.2); both remained stable throughout the analyzed period. Being 35-54 years old and having low educational attainment were the main factors associated with both consumption patterns. Being Indigenous was highly associated only with excessive alcohol consumption, whereas being legally married and living in Northern Brazil were protective factors. Conclusion These findings emphasize the need for focused preventive strategies targeting the most vulnerable groups to mitigate alcohol consumption and its associated risks during pregnancy.

Abstract Background Passive smoking, which affects a large number of people, may create a predisposition to cardiovascular disease in a manner similar to active smoking. However, this relationship is poorly explored in the scientific literature. Objectives This study aimed to investigate the association between passive smoking and hypertension in an adult population in Brazil. Methods This panel study utilized data on the Brazilian population collected through a VIGITEL survey conducted between 2009 and 2021. The data were analyzed using Poisson regression with a 95% confidence interval (95%CI). Results The prevalence of hypertension in our population was 24.9% (95%CI 24.6-25.1), and passive smoking was observed in 16.3% (95%CI 16.0-16.5). The adjusted analysis revealed that passive smoking leads to a high risk of hypertension (PR=1.10; 95%CI 1.07 to 1.14), which was surprisingly close to the risk among heavy smokers (>1 pack or 20 cigarettes a day) (PR 1.09; 95%CI 1.06 to 1.13). Another noteworthy finding was the higher prevalence of hypertension among former smokers, highlighting associations that are poorly explained in the literature. Conclusion A significant association was found between passive smoking and hypertension, demonstrating that passive smokers are as prone to developing hypertension as heavy smokers. Therefore, we recommend a meta-analysis to consolidate the evidence on this subject and strengthen our findings.

Resumo Fundamento O tabagismo passivo (TP), que afeta um grande número de pessoas, pode criar uma predisposição para doenças cardiovasculares de forma semelhante ao tabagismo ativo. No entanto, essa relação é pouco explorada na literatura científica. Objetivos Este estudo teve como objetivo investigar a associação entre TP e hipertensão em uma população adulta no Brasil. Métodos Este estudo de painel utilizou dados da população brasileira coletados por meio de uma pesquisa VIGITEL realizada entre 2009 e 2021. Os dados foram analisados por meio de regressão de Poisson com intervalo de confiança de 95% (IC95%). Resultados A prevalência de hipertensão em nossa população foi de 24,9% (IC95% 24,6-25,1), e o TP foi observado em 16,3% (IC95% 16,0-16,5). A análise ajustada revelou que o TP leva a um alto risco de hipertensão (RP=1,10; IC95% 1,07 a 1,14), que foi surpreendentemente próximo ao risco entre fumantes pesados (>1 maço ou 20 cigarros por dia) (RP 1,09; IC95% 1,06 a 1,13). Outro achado digno de nota foi a maior prevalência de hipertensão entre ex-fumantes, destacando associações que estão mal explicadas na literatura. Conclusão Foi encontrada uma associação significativa entre TP e hipertensão, demonstrando que fumantes passivos são tão propensos a desenvolver hipertensão quanto fumantes pesados. Portanto, recomendamos uma meta-análise para consolidar as evidências sobre este assunto e fortalecer nossas descobertas.

RESUMO Objetivo Avaliar a prevalência do uso de drogas ilícitas nos anos de 2015 e 2019 entre estudantes de graduação de uma universidade pública do sul do Brasil, observando diferenças na proporção do uso dessas substâncias nesse período, bem como os fatores associados a esse comportamento. Métodos Estudo de painel, realizado a partir de duas pesquisas com corte transversal, nos anos de 2015 e 2019. Os dados foram coletados através de questionário autoadministrado. Realizou-se análise multivariada, por meio da regressão de Poisson. Resultados Participaram 1.423 estudantes em 2015 e 996 estudantes em 2019. A prevalência do uso de drogas ilícitas na vida, no ano e no mês aumentou entre os dois anos de estudo e as drogas mais utilizadas foram maconha, seguida por drogas sintéticas. As variáveis independentes associadas ao uso de drogas ilícitas no último mês nas duas pesquisas foram migração acadêmica, ser do sexo masculino, ter entre 18 e 24 anos, morar com amigos, ter um familiar que usa ou já usou drogas, ter um amigo que usa ou já usou drogas, ter usado álcool no último mês e ter usado tabaco no último mês. A prática religiosa foi fator de proteção. Conclusão A tendência do uso de drogas ilícitas mostrou-se crescente. Estudantes que migram de suas cidades para estudar na universidade apresentam maior prevalência de uso de drogas ilícitas no último mês. Diante destes resultados, sugerimos a criação de programas de acolhimento e acompanhamento dos estudantes com especial atenção para aqueles que migram de outras cidades para estudar.

ABSTRACT Objective To assess the prevalence of illicit drug use in the years 2015 and 2019 among undergraduate students at a public university in southern Brazil, examining differences in the proportion of substance use during this period, as well as the factors associated with this behavior. Methods A panel study conducted from two cross-sectional surveys in 2015 and 2019. Data were collected through self-administered questionnaires. Multivariate analysis was performed using Poisson regression. Results 1,423 students participated in 2015, and 996 students participated in 2019. The prevalence of lifetime, past-year, and past-month illicit drug use increased between the two study years, with marijuana being the most commonly used drug, followed by synthetic drugs. Independent variables associated with illicit drug use in the past month in both surveys were academic migration, being male, aged 18 to 24 years, living with friends, having a family member who currently or previously used drugs, having a friend who currently or previously used drugs, using alcohol in the past month, and using tobacco in the past month. Religious practice was a protective factor. Conclusion The trend of illicit drug use showed an increasing pattern. Students who migrate from their hometowns to study at the university have a higher prevalence of illicit drug use in the past month. In light of these results, we suggest the implementation of programs to support and monitor students, with particular attention to those who migrate from other cities to study.

ABSTRACT Objective: We aimed to analyze the frequency of adherence to social distancing and individual protection measures of adult and older populations in two cities in southern Brazil and to characterize the sociodemographic aspects of these individuals. Methods: This cross-sectional, population-based study was conducted in the cities of Rio Grande, RS, and Criciúma, SC, Brazil. The outcome measure was the frequency of adherence to social distancing measures. Fisher's exact test (5% significance) was used to calculate the differences in prevalence according to exposure variables. Results: Among the 2,170 participants over the age of 18, the prevalence of adherence to social distancing was 18.5%. Adherence was significantly higher among women; older adults; single, divorced, or widowed people with a low educational level; people of lower socioeconomic status; and people affected by multiple chronic diseases. Conclusion: Approximately one in five respondents adhered to measures of social distancing, and adherence was more prevalent among the risk groups.

RESUMO Objetivo: Analisar se a pandemia da COVID-19 está associada ao aumento do sentimento de tristeza entre adultos e idosos do sul do Brasil. Métodos: Dois estudos transversais de base populacional foram conduzidos com a mesma população-alvo em 2016 e 2020 com indivíduos com 18 anos ou mais. O desfecho foi o sentimento de tristeza, medido pela escala de faces. As variáveis de exposição foram infecção pelo coronavírus SARS-COV-19, contato com alguém infectado pela COVID-19, presença de algum sintoma da COVID-19, trabalho remoto após a pandemia, distanciamento social, comportamento infodêmico e medo da COVID-19. Resultados: No geral, 1.300 (2016) e 1.307 (2020) indivíduos foram entrevistados no seus domicílios. A prevalência de tristeza foi de 9,0% (IC95% 6,9 a 11,2) em 2016 e 15,2% (IC95% 12,3 a 18,0) em 2020. A única variável do cenário pandêmico associada à tristeza foi o medo da COVID-19. Indivíduos com maior medo da pandemia tiveram 50% mais probabilidade de se sentirem tristes. No entanto, esse efeito desapareceu quando o estresse foi incluído no modelo de análise. Conclusões: Foi observado aumento na prevalência de tristeza, mostrando que o medo da COVID-19 esteve associado a maior frequência de tristeza. Essa associação foi provavelmente mediada pelo nível de estresse.

ABSTRACT Objective: To analyze whether the COVID-19 pandemic is associated with an increment in the feeling of sadness among adults and elderly individuals from southern Brazil. Methods: Two cross-sectional population-based studies were conducted with the same target population in 2016 and 2020 with individuals aged 18 years or older. The outcome was a feeling of sadness, measured through the scale of faces. The exposure variables were infection by the coronavirus SARS-COV-19, contact with someone infected by COVID-19, presence of any symptoms of COVID-19, remote work after the pandemic, social distancing, infodemic behavior, and fear of COVID-19. Results: Overall, 1,300 (2016) and 1,307 (2020) individuals were interviewed at home. The prevalence of sadness was 9.0% (95% CI 6.9 to 11.2) in 2016 and 15.2% (95% CI 12.3 to 18.0) in 2020. The only variable of the pandemic setting associated with sadness was fear of COVID-19. Individuals with a higher fear of the pandemic were 50% more likely to be sad. However, this effect disappeared when stress was included in the model. Conclusions: An increase in the prevalence of sadness was observed, showing that fear of COVID-19 was associated with a greater frequency of sadness. This association was probably mediated by stress level.

ABSTRACT Objective: To compare the glucose metabolism of patients with chronic hepatitis C virus infection treated with direct-acting antivirals (DAAs) in pretreatment and sustained viral response (SVR) periods. Materials and methods: This was an intervention pre-post study of 273 patients with chronic hepatitis C virus infection treated with DAAs from March 2018 to December 2019. Glycidic metabolism was evaluated through homeostasis model assessment (HOMA) – insulin resistance (IR) and HOMA-β indices and assessments of insulinemia and HbA1c levels. These parameters were analyzed with a T test by paired comparison of the means of the variables and Wilcoxon's test paired for the median; in the variables with an abnormal distribution, the Z score was generated for the mean in both the pretreatment and SVR periods. Statistical significance was considered at p ≤ 0.05. Results: Among 273 participants, 125 (45.8%) had prediabetes, and 50 (18.3%) had diabetes. In SVR, there was a significant increase in platelets, albumin, alkaline phosphatase, cholesterol and triglycerides and a significant decrease in aspartate aminotransferase, alanine aminotransferase, gamma GT and bilirubin. The HOMA-IR and HOMA-β indices increased in SVR from 1.95 to 2.29 (p = 0.087) and 71.20 to 82.60 (p = 0.001), respectively. Insulinemia increased from 7.60 μU/mL to 8.90 μU/mL (p = 0.011). HbA1c decreased from 5.6 to 5.4 (p < 0.001). Among patients with prediabetes and those with diabetes, the reduction in HbA1c values was significant (p = 0.006 and p = 0.026, respectively). Conclusion: SVR significantly impacts and leads to improvement in glucose metabolism in patients with chronic liver disease induced by hepatitis C virus.

Resumo Investigar fatores associados a pior qualidade do sono. Estudo transversal realizado em 2019, com amostragem aleatória sistemática. Informações sobre sono foram obtidas através do Mini Sleep Questionaire (MSQ). Variáveis independentes incluíram características sociodemográficas, comportamentais, acadêmicas e de saúde psicológica. Análises ajustadas foram feitas com regressão de Poisson. Participaram 996 estudantes de graduação. A pior qualidade de sono atingiu 23,1% da amostra (IC95% 20,5-25,9), oscilando de 13,4% para os com pouca preocupação com violência no bairro a 36,5% para aqueles com menor suporte social. Na análise ajustada, sexo feminino [RP] 1,81; (IC95% 1,33-2,45), preocupação com violência no bairro [RP] 2,21; (IC95% 1,48-3,28), discriminação na universidade [RP] 1,42; (IC95% 1,08-1,86) e insegurança alimentar [RP] 1,45; (IC95% 1,11-1,89) associaram-se a presença de pior qualidade do sono, assim como ter menor suporte social e renda e apresentar sofrimento psicológico. Os resultados destacam fatores socioeconômicos e de saúde mental que interferem na qualidade do sono e demonstram a necessidade de reflexão e proposição de intervenções capazes de minimizar este problema. 2019 sistemática MSQ.

Abstract To investigate factors associated with poor sleep quality. A cross-sectional study was conducted in 2019 with random sampling. Information on sleep was obtained using the Mini Sleep Questionnaire (MSQ). Independent variables included sociodemographic, behavioural, academic and psychological health characteristics. Adjusted analyzes were performed using Poisson regression. A total of 996 undergraduate students participated in the study. The poor sleep quality affected 23.1% of the sample (95%CI 20.5-25.9), ranging from 13.4% for those with little concern about violence in the neighbourhood to 36.5% for those with less social support. In the adjusted analysis, female sex [PR] 1.81; (95%CI 1.33-2.45), concern about violence in the neighbourhood [PR] 2.21; (95%CI 1.48-3.28), discrimination at university [PR] 1.42; (95%CI 1.08-1.86) and food insecurity [PR] 1.45; (95%CI 1.11-1.89) were associated with the presence of poor sleep quality, as well as having less social support and income and suffering psychological distress. The results highlight socioeconomic and mental health factors that affect sleep quality and demonstrate the need for reflection and interventions capable of minimizing this problem. crosssectional cross sectional 201 sampling MSQ.

Resumo O objetivo deste artigo é investigar a associação entre trabalho remoto e dores nas costas durante a pandemia da COVID-19 e analisar essa relação segundo o índice de massa corporal. Estudo transversal de base populacional realizado em duas cidades no sul do Brasil em indivíduos acima de 18 anos. Dados foram coletados por meio de entrevistas domiciliares entre outubro-janeiro de 2020-2021. Desfechos: dor nas costas (cervical, torácica, lombar/aguda, crônica) e intensidade da dor. Variável de exposição: trabalho remoto. Para as análises, foram utilizadas regressão de Poisson com ajuste robusto para variância, estratificadas pelo IMC (eutrófico vs. sobrepeso/obeso) e restritas àqueles que trabalharam no último mês. Durante a pandemia, 1.016 trabalharam, média 42 anos (DP = 14), entre 18 a 93 anos. Trabalho remoto foi realizado por 7,7% dos indivíduos. Prevalência de dor nas costas: 25.6% (IC95%:19,5 a 31,7%). Trabalhadores remotos com sobrepeso/obesidade sentiram dor aguda cervical RP = 2,82 (IC95%:1,15 a 6,92); torácica aguda RP = 1,81 (IC95%:3,76 a 8,68); lombar crônica RP = 1,85 (IC95%:1,04 a 3,29), comparados àqueles que não trabalharam. Cerca de um em cada quatro trabalhadores remotos reportou dor nas costas durante a pandemia. O IMC mostrou-se ser um importante moderador entre defechos e variável de exposição.

Abstract This article aims to investigate the association between remote work and Back Pain during the COVID-19 pandemic, and to analyze this relationship according to the body mass index. Population-based, cross-sectional study carried in two cities in southern Brazil, in individuals aged 18 years and over. Data were collected through household interviews from October to January 2020/21. Outcomes: back pain (cervical, thoracic, lumbar/acute, chronic) and pain intensity. Exposure variable: remote work. For the analyses, Poisson regression with robust adjustment for variance was used, stratified by BMI (eutrophic vs overweight/obese), and restricted to those who had worked in the past month. 1,016 had worked during the pandemic, average 42 years old (SD = 14), varying from 18 to 93 years. Remote work was performed by 7.7% of the individuals. Prevalence of back pain: 25.6% (95%CI: 19.5 to 31.7%). Overweight/obese remote workers felt pain acute cervical pain PR = 2.82 (95%CI: 1.15 to 6.92); chronic low back PR = 1.85 (95%CI: 1.04 to 3.29); acute thoracic PR = 1.81(95%CI: 3.76 to 8.68) compared to those who did not work.

Abstract Introduction There are several negative impacts on the physical and mental health of people presenting internet addiction, including development of mood disorders, such as depression. Objective The aim of the study was to evaluate the association between internet addiction and depressive symptoms, as well as to test the mediating role of physical activity in this association. Methods A cross-sectional study was conducted with undergraduate students from three universities (one private and two public institutions) in southern Brazil. Depressive symptoms were measured with the Beck Depression Inventory (BDI-21), internet addiction with the Internet Addiction Test (IAT-20), and physical activity with the International Physical Activity Questionnaire (IPAQ – short version). Poisson regression and the Karlson-Holm-Breen mediation method were used for statistical analyses. Results We observed a dose-response relationship between internet addiction and depressive symptoms. Levels of physical activity mediated the association between moderate internet addiction and depressive symptoms, accounting for 10.7% of the effect observed. Conclusion Internet addiction can be detrimental to individuals’ health, contributing to development of depressive symptoms. Along with psychological and pharmacological therapies, prescription of physical activities is recommended. disorders depression crosssectional cross sectional one institutions Brazil BDI21, BDI21 BDI 21 , (BDI-21) IAT20, IAT20 IAT 20 (IAT-20) IPAQ version. version . version) KarlsonHolmBreen Karlson Holm Breen analyses doseresponse dose response 107 10 7 10.7 individuals therapies recommended BDI2 2 (BDI-21 IAT2 (IAT-20 1 10.

RESUMO Objetivo: Investigar a prevalência e os fatores associados ao risco de suicídio em estudantes do ensino médio de uma instituição federal de ensino do Rio Grande do Sul (IFRS). Métodos: Trata-se de um estudo transversal realizado com base em um censo de estudantes (n=510) matriculados no IFRS, Campus Rio Grande, no segundo semestre de 2019. Os dados foram coletados por meio de questionário autoaplicável. O risco de suicídio foi medido com o instrumento Mini-International Neuropsychiatric Interview e a análise dos dados foi conduzida por meio de regressão de Poisson com ajuste robusto da variância. Resultados: A prevalência do risco alto de suicídio foi de 17,3% (intervalo de confiança — IC95% 14,0–20,0), tendo como fatores independentemente associados: sexo feminino, maior nível socioeconômico, consumo de álcool, menor suporte social, tentativa de perder peso, comportamento autolesivo e maior risco de depressão, ansiedade e estresse. Conclusões: Um em cada seis estudantes apresentou elevado risco de suicídio. A identificação dos fatores associados ao desfecho é útil para identificar os casos mais graves e encaminhá-los para atendimento especializado.

ABSTRACT Objective: To investigate the prevalence and factors associated with suicide risk among high school students from a federal educational institution in Rio Grande do Sul (IFRS). Methods: This is a cross-sectional study based on a census of students (n=510) enrolled in IFRS, campus Rio Grande, in the second half of 2019. Data were collected through a self-administered questionnaire. Suicide risk was measured with the instrument Mini-International Neuropsychiatric Interview, and data were analyzed using Poisson regression with robust variance adjustment. Results: The prevalence of high suicide risk was 17.3% (95% confidence interval — 95%CI 14.0–20.0), with the following independent associated factors: female gender, higher socioeconomic status, alcohol consumption, less social support, attempt to lose weight, self-harm behavior, and increased risk of depression, anxiety, and stress. Conclusions: One in six students showed a high suicide risk. The identification of factors associated with the outcome is useful for detecting the most severe cases and referring them to specialized care.

Resumo Investigar fatores associados a pior qualidade do sono. Estudo transversal realizado em 2019, com amostragem aleatória sistemática. Informações sobre sono foram obtidas através do Mini Sleep Questionaire (MSQ). Variáveis independentes incluíram características sociodemográficas, comportamentais, acadêmicas e de saúde psicológica. Análises ajustadas foram feitas com regressão de Poisson. Participaram 996 estudantes de graduação. A pior qualidade de sono atingiu 23,1% da amostra (IC95% 20,5-25,9), oscilando de 13,4% para os com pouca preocupação com violência no bairro a 36,5% para aqueles com menor suporte social. Na análise ajustada, sexo feminino [RP] 1,81; (IC95% 1,33-2,45), preocupação com violência no bairro [RP] 2,21; (IC95% 1,48-3,28), discriminação na universidade [RP] 1,42; (IC95% 1,08-1,86) e insegurança alimentar [RP] 1,45; (IC95% 1,11-1,89) associaram-se a presença de pior qualidade do sono, assim como ter menor suporte social e renda e apresentar sofrimento psicológico. Os resultados destacam fatores socioeconômicos e de saúde mental que interferem na qualidade do sono e demonstram a necessidade de reflexão e proposição de intervenções capazes de minimizar este problema.

Abstract To investigate factors associated with poor sleep quality. A cross-sectional study was conducted in 2019 with random sampling. Information on sleep was obtained using the Mini Sleep Questionnaire (MSQ). Independent variables included sociodemographic, behavioural, academic and psychological health characteristics. Adjusted analyzes were performed using Poisson regression. A total of 996 undergraduate students participated in the study. The poor sleep quality affected 23.1% of the sample (95%CI 20.5-25.9), ranging from 13.4% for those with little concern about violence in the neighbourhood to 36.5% for those with less social support. In the adjusted analysis, female sex [PR] 1.81; (95%CI 1.33-2.45), concern about violence in the neighbourhood [PR] 2.21; (95%CI 1.48-3.28), discrimination at university [PR] 1.42; (95%CI 1.08-1.86) and food insecurity [PR] 1.45; (95%CI 1.11-1.89) were associated with the presence of poor sleep quality, as well as having less social support and income and suffering psychological distress. The results highlight socioeconomic and mental health factors that affect sleep quality and demonstrate the need for reflection and interventions capable of minimizing this problem.

ABSTRACT The aim of this study was to verify the association between the degree of wisdom and the level of leisure-time physical activity (PA) of students from a federal public school in southern Brazil. Observational cross-sectional study with 462 young people of both sexes between 15 and 18 years old. Data collection was performed using a self-administered questionnaire on the REDCap platform. The independent variable was the “level of leisure PA” (inactive, insufficiently active, and physically active) and the outcome was the “degree of wisdom” evaluated through a validated questionnaire (SD-WISE7). There was a linear trend towards an increase in the wisdom score according to the level of PA. This trend and significant association continued in the adjusted analysis, with active students averaging 1.84 points more in the wisdom score compared to inactive students. In conclusion, the wisest young people are also the most physically active young people. In view of the potential beneficial effects, current studies may consider wisdom as a possible mediator of PA with health outcomes.

RESUMO O objetivo deste estudo foi verificar a associação entre o grau de sabedoria e o nível de atividade física de lazer (AF) de alunos de uma escola pública federal do sul do Brasil. Estudo observacional de corte transversal com 462 jovens de ambos os sexos entre 15 e 18 anos de idade. A coleta de dados foi realizada por meio de um questionário autoaplicável na plataforma REDCap. A variável independente foi o “nível de AF de lazer” (inativo, insuficientemente ativo e ativo fisicamente) e o desfecho foi a “grau de sabedoria” avaliados por meio de questionários validados. Observou-se tendência linear de aumento do escore de sabedoria conforme o nível de AF. Essa tendência e associação significativa se manteve na análise ajustada, com os ativos tendo em média 1.84 pontos a mais no escore de sabedoria em comparação aos inativos. Em conclusão, os jovens mais sábios também são os jovens mais ativos fisicamente. Tendo em vista os potenciais efeitos benéficos, os estudos atuais podem considerar a sabedoria como um possível mediador da AF com desfechos em saúde.
