Resultados: De 45.161 brasileiros respondentes, verificou-se que, durante a pandemia, 40,4% (IC95% 39,0;41,8) se sentiram frequentemente tristes ou deprimidos, e 52,6% (IC95% 51,2;54,1) frequentemente ansiosos ou nervosos; 43,5% (IC95% 41,8;45,3) relataram início de problemas de sono, e 48,0% (IC95% 45,6;50,5) problema de sono preexistente agravado. Tristeza, nervosismo frequentes e alterações do sono estiveram mais presentes entre adultos jovens, mulheres e pessoas com antecedente de depressão. Conclusão: As elevadas prevalências encontradas indicam a necessidade de garantir a provisão de serviços de atenção à saúde mental e à qualidade do sono, adaptados ao contexto pandêmico.

Background Physical inactivity and sedentary behavior are major concerns for public health. Although global initiatives have been successful in monitoring physical activity (PA) worldwide, there is no systematic action for the monitoring of correlates of these behaviors, especially in low- and middle-income countries. Here we describe the prevalence and distribution of PA domains and sitting time in population sub-groups of six south American countries. Methods Data from the South American Physical Activity and Sedentary Behavior Network (SAPASEN) were used, which includes representative data from Argentina ( n = 26,932), Brazil ( n = 52,490), Chile ( n = 3719), Ecuador ( n = 19,851), Peru ( n = 8820), and Suriname ( n = 5170). Self-reported leisure time (≥150 min/week), (≥150 min/week), transport (≥10 min/week), and occupational PA total (≥10 min/week), as well as sitting time (≥4 h/day) were captured in each national survey. Sex, age, income, and educational status were exposures. Descriptive statistics and harmonized random effect meta-analyses were conducted. Results The prevalence of PA during leisure (Argentina: 29.2% to Peru: 8.6%), transport (Peru: 69.7% to Ecuador: 8.8%), and occupation (Chile: 60.4 to Brazil 18.3%), and ≥4 h/day of sitting time (Peru: 78.8% to Brazil: 14.8%) differed widely between countries. Moreover, total PA ranged between 60.4% (Brazil) and 82.9% (Chile) among men, and between 49.4% (Ecuador) and 74.9% (Chile) among women. Women (low leisure and occupational PA) and those with a higher educational level (low transportation and occupational PA as well as high sitting time) were less active. Concerning total PA, men, young and middle-aged adults of high educational status (college or more) were, respectively, 47% [OR = 0.53 (95% CI = 0.36–0.78), I 2 = 76.6%], 25% [OR = 0.75 (95% CI = 0.61-0.93), I 2 = 30.4%] and 32% [OR = 0.68 (95% CI = 0.47-1.00), I 2 = 80.3%] less likely to be active. Conclusions PA and sitting time present great ranges and tend to vary across sex and educational status in South American countries. Country-specific exploration of trends and population-specific interventions may be warranted.

Our aim was to analyze the association between previously diagnosed lifetime depression and changes in physical activity (PA), TV-viewing, consumption of fruits and vegetables as well as frequency of ultra-processed food (UPF) consumption. Data of 41,923 Brazilian adults (6,881 with depression and 35,042 without depression) were used. Participants reported PA (≥ 150 min/week), TV-viewing (≥ 4 h/day), frequency of eating fruits or vegetables (≤ 4 days/week) and UPF (≥ 5 days/week). For incidence indicators, we only considered participants without the risk behavior before the quarantine. People without and with depression presented, respectively, incidence of physical inactivity [70.1% (95%CI: 67.4-72.8) vs 76.3 (70.3-81.5)], high TV-viewing [31.2 (29.6-32.8) vs 33.9 (30.5-37.4)], low frequency of fruit or vegetable consumption [28.3 (25.8-31.0) vs 31.5 (26.1-37.5)] and elevated frequency of UPF consumption [9.7 (8.9-10.7) vs 15.2 (13.0-17.7)]. Participants with depression were more likely to present elevated frequency of UPF consumption incidence [OR:1.49 (95%CI:1.21-1.83)]. Thus, participants with previous diagnosis of depression were at risk for incidence of unhealthy diet behaviors.

Introduction The Coronavirus disease-19 (COVID-19) pandemic affected countries worldwide and has changed peoples’ lives. A reduction in physical activity and increased mental health problems were observed, mainly in the first year of the COVID-19 pandemic. Thus, this systematic review aims to examine the association between physical activity and mental health during the first year of the COVID-19 pandemic. Methods In July 2021, a search was applied to PubMed, Scopus, and Web of Science. Eligibility criteria included cross-sectional, prospective, and longitudinal study designs and studies published in English; outcomes included physical activity and mental health (e.g., depressive symptoms, anxiety, positive and negative effects, well-being). Results Thirty-one studies were included in this review. Overall, the studies suggested that higher physical activity is associated with higher well-being, quality of life as well as lower depressive symptoms, anxiety, and stress, independently of age. There was no consensus for the optimal physical activity level for mitigating negative mental symptoms, neither for the frequency nor for the type of physical activity. Women were more vulnerable to mental health changes and men were more susceptive to physical activity changes. Conclusion Physical activity has been a good and effective choice to mitigate the negative effects of the COVID-19 pandemic on mental health during the first year of the COVID-19 pandemic. Public health policies should alert for possibilities to increase physical activity during the stay-at-home order in many countries worldwide.

Background Our aim was to investigate the mediating role of worsening sleep quality in the association of the incidence of physical inactivity, high TV-viewing, and high computer/tablet use with loneliness, sadness, and anxiety. Methods Data of 45,160 Brazilian adults from a nationwide behavior survey, conducted between April 24th and May 24th (2020), were used. Participants reported physical inactivity (PI; <150 min/week), high TV-viewing (TV; ≥4 h/day), and high computer/tablet use (PC; ≥4 h/day) before and during COVID-19 quarantine (exposures). For incidence indicators, we only considered participants without the risk behavior before quarantine. Changes in sleep quality during the quarantine period (maintained/got better or worsened) were treated as a mediator. Elevated frequencies of feelings of loneliness, sadness (feel sad, crestfallen, or depressed), and anxiety (feel worried, anxious, or nervous) during the pandemic period were the study outcomes. Analyses were adjusted for sex, age group, highest academic achievement, working status during quarantine, skin color, previous diagnosis of depression, and adherence to quarantine. Mediation models were created using the Karlson Holm Breen method. Results The incidence of PI, high TV, and high PC use was associated with loneliness, sadness, and anxiety feelings. Worsening sleep quality partly mediated the association of the incidence of PI, high TV, and high PC use with loneliness (PI:30.9%; TV:19.6%; PC: 30.5%), sadness (PI:29.8%; TV:29.3%; PC: 39.1%), and anxiety (PI:21.9%; TV:30.0%; PC:38.5%). Conclusion The association of the incidence of physical inactivity and sedentary behaviors with mental health indicators is partly mediated by worsening sleep quality during the COVID-19 pandemic quarantine.

Resumo: O presente estudo tem o objetivo de caracterizar a população idosa brasileira durante a pandemia de COVID-19, considerando suas condições de saúde, socioeconômicas, desigualdade de sexo, adesão ao distanciamento social e sentimento de tristeza ou depressão. Estudo transversal realizado com idosos brasileiros que participaram de um inquérito de saúde (N = 9.173), com método de amostragem “bola de neve virtual”. Os dados foram coletados via web, por meio de questionário autopreenchido. Foram estimadas prevalências, intervalos de confiança e, para verificar a independência das estimativas, utilizou-se o teste qui-quadrado de Pearson. Durante a pandemia, houve diminuição da renda em quase metade dos domicílios dos idosos. O distanciamento social total foi adotado por 30,9% (IC95%: 27,8; 34,1) e 12,2% (IC95%: 10,1; 14,7) não aderiram. Idosos que não trabalhavam antes da pandemia aderiram em maior número às medidas de distanciamento social total. Grande parte apresentou comorbidades associadas ao maior risco de desenvolvimento da forma grave de COVID-19. Sentimentos de solidão, ansiedade e tristeza foram frequentes entre os idosos, especialmente entre as mulheres. A pandemia da COVID-19 aprofundou a desigualdade ao afetar os idosos mais vulneráveis. Estratégias para mitigar a solidão e o distanciamento social devem ser feitas levando-se em conta a vulnerabilidade social e a acentuada diferença entre homens e mulheres quanto à composição domiciliar e às condições socioeconômicas e de trabalho. Recomenda-se o desenvolvimento de pesquisas representativas da população idosa brasileira e que investiguem o impacto da pandemia neste grupo.
