Effect of circuit training and walking on glycemic control in type 2 diabetic women assisted in primary care clinic in Pelotas/RS, 2017: A randomized trial / Efecto del entrenamiento en circuito y de la caminata sobre el control glicémico de mujeres diabéticas tipo 2 atendidas en clínicas de atención primária de Pelotas/RS, 2017: Ensayo aleatorio / Efeito do treinamento em circuito e da caminhada sobre o controle glicêmico de mulheres diabéticas tipo 2 assistidas em unidades básicas de saúde de Pelotas/RS, 2017: Ensaio randomizado

Objective: compare the effects of circuit training and walking on glycemic control in women with type 2 diabetes. Methods: this randomized trial in primary  care clinic. The primary outcomes assessed were glycated hemoglobin and fasting blood glucose. Two primary health care were randomized to the circuit training and three to the walking, including 41 women (circuit=28; walking=13). Intra- and inter-group comparisons were conducted by intention-to-treat. Results:  no changes were observed in glycated hemoglobin (p=0.209) and fasting blood glucose (p=0.123). Localized muscular resistance of the lower limbs and cardiorespiratory fitness increased in the functional training (p=0.002; p=0.009, respectively), and blood pressure decreased significantly in both groups (p=0.006; p=0.046, respectively). Conclusion: the interventions did not improve glycemic control. Circuit training was effective in improving physical fitness, and both models were effective in controlling participants' blood pressure.

Exercise as medicine! Physical activity mitigated the impact of the COVID-19 pandemic on depressive symptoms in adults with depression.

We investigated the longitudinal association between physical activity (PA) and symptoms of depression and anxiety in people with depression during the COVID-19 pandemic. We used data from baseline (June 2020) to wave 3 (June 2021) of the PAMPA Cohort, an ambispective cohort with adults in south Brazil. The Hospital Anxiety and Depression Scale assessed depressive and anxiety symptoms in all waves. Participants reported frequency (minutes), type (aerobic, strength, combined), and place (out of home, at home) of physical activity at baseline. Generalized linear models were used to investigate the interaction between time and PA, adjusting for possible confounding variables. Subjective memory decline was assessed using multivariate Cox proportional hazard regression models to obtain adjusted hazard ratio (HR) and respective 95% confidence interval (CI). Participants (n = 424) with self-reported clinically diagnosed depression were included. We observed a non-linear increase trajectory of depression during the first year of the COVID-19 pandemic. PA was associated with a slower trajectory of depressive (slope: -1.89; 95%CI: -3.34, -0.43 points) but not anxiety (slope: -1.33; 95%CI: -2.93, 0.25 points) symptoms during the COVID-19 pandemic. Participants who continued physically active from pre-pandemic in wave 1 showed a lower risk of subjective memory decline during follow-up than those who persisted inactive in the same period (HR: 0.52; 95%CI: 0.30, 0.89). PA attenuated the impact of the COVID-19 pandemic on depressive symptoms in adults living with depression in south Brazil. Regularity of physical activity was associated with fewer depression and anxiety symptoms and a lower risk of subjective memory decline.

Longitudinal impact of leisure-time physical activity on pain intensity and daily activity limitation in people with low back pain. Findings from the PAMPA cohort.

OBJECTIVE: We aimed to prospectively evaluate the association between leisure-time physical activity and outcomes related to low back pain (LBP), such as pain intensity and daily activity limitation. METHODS: We analyzed data from the PAMPA (Prospective Study about Mental and Physical Health) cohort, a longitudinal study with adults residing in Southern Brazil. Participants answered an online-based, self-administered questionnaire. Physical activity was assessed as minutes per week, and those who reported engaging in 150 min/week or more were considered active. We also assessed the types of activities participants engaged. Pain intensity was assessed with a numeric pain rating scale (from 0 to 10), and participants reported whether their pain restricted their daily activities. Generalized linear models were used to investigate the association between physical activity and LBP outcomes. RESULTS: Data from 991 individuals (82.7% women) aged 38.9 ± 13.9 were analyzed. Pain intensity was higher in those inactive in waves one (ß: 0.54; 95 % CI 0.23, 0.86), three (ß: 0.38; 95% CI 0.02, 0.75), and four (ß: 0.48; 95% CI 0.06, 0.90). Also, being physically inactive at wave one was associated with a higher probability of daily activity limitation at waves two (IRR 1.77; 95% CI 1.27; 2.46), three (IRR 1.63; 95% CI 1.17, 2.29), and four (IRR 1.73; 95% CI 1.20, 2.50). CONCLUSION: Not practicing at least 150 min/week of physical activity resulted in higher levels of pain and an increased risk of daily activity limitation in individuals with LBP. Moreover, various forms of activities have shown to be advantageous in alleviating pain among this group.

Potentially modifiable risk factors for dementia in six low-income and middle-income countries: A multinational, population-based survey.

OBJECTIVES: We aimed to determine the proportion of dementia cases potentially preventable in six low-income and middle-income countries. STUDY DESIGN: We analyzed data from 19,278 adults aged 50 years or more from China, South Africa, Ghana, India, Russia, and Mexico included in the WHO's Study on global AGEing and adult health. MAIN OUTCOME MEASURES: We calculated the population attributable fraction for ten potentially modifiable risk factors: less education, hearing loss, hypertension, diabetes, depression, heavy drinking, obesity, smoking, physical inactivity, and social isolation. Weighted attributable fraction was calculated considering communality among risk factors. RESULTS: We estimated that 37.6 % of the burden of dementia might be attributable to these risk factors. The highest and lowest overall weighted attributable fractions were 38.3 % and 22.9 % in China and Ghana, respectively. Less education (8.3 %), smoking (6.3 %), and physical inactivity (5.7 %) showed the highest attributable fraction for dementia. The overall attributable fraction was higher in the poorest (38.1 %) than in the richest (30.9 %) income quintile. The burden of obesity, diabetes, and hypertension was 61 % higher in the wealthiest than in the poorest population. A total of 7.2 million cases of dementia in these six low- and middle-income countries are potentially caused by these ten potentially modifiable risk factors. CONCLUSIONS: Overall, 38 % of cases of dementia in China, South Africa, Ghana, India, Russia, and Mexico can be attributable to ten potentially modifiable risk factors. Cardiometabolic risk factors account for a more significant burden of dementia in the wealthiest population. Less education had the highest population attributable fraction independent of living area and income.

Caffeine Supplementation Effects on Concurrent Training Performance in Resistance-Trained Men: A Double-Blind Placebo-Controlled Crossover Study.

Purpose: The aim of the present study was to investigate the effects of acute caffeine supplementation on the performance during a session of resistance training alone (RT) or in combination with aerobic training (i.e. concurrent training; CT). Method: Fourteen resistance-trained men (23.1 ± 4.2 years) were recruited and performed both RT and CT under three different conditions: control (CONT), placebo (PLA), and caffeine (CAF; 6 mg.kg-1) for a total of six experimental conditions. Results: Both total and per set number of repetitions, and total volume load were lower during CT as compared to RT, irrespective of the supplementation condition (all p < .001), whereas a supplementation main effect was observed for the total number of repetitions (p = .001), the number of repetitions in the first (p = .002) and second sets (p = .001), and total volume load (p = .001). RPE values were higher after the CT sessions than after the RT sessions (p < .001), whereas no differences were observed between supplementation conditions (p = .865). Conclusions: Caffeine supplementation was not sufficient to minimize the acute interference effect on strength performance in a CT session when compared to RT alone. In contrast, caffeine improved strength performance during the first set of both CT and RT, while maintaining a similar RPE between the supplementation conditions. However, the overall effect was small.

Prevalence and factors associated with long COVID in adults from Southern Brazil: findings from the PAMPA cohort.

Most COVID-19 survivors have reported experiencing persistent symptoms after the infection - these types of cases are known as long COVID. Since Brazil was an epicenter of the COVID-19 pandemic, a high burden of long COVID is expected. This study aimed to identify the prevalence and factors associated with long COVID in adults in Southern Brazil, analyzing data from the PAMPA cohort. Participants filled out a self-reported online questionnaire in June 2022. This study only included subjects who tested positive for COVID-19. Long COVID was defined by any symptoms that persisted for at least three months after the SARS-CoV-2 infection. Poisson's regression models with robust variance were used to identify factors associated with long COVID; and results were reported as prevalence ratios (PR) and respective 95% confidence intervals (95%CI). A total of 1,001 participants (77.4% women, mean age [SD] = 38.3 [11.9] years) were analyzed. The prevalence of long COVID among these patients was 77.4% (95%CI: 74.7; 79.9). The likelihood of long COVID was higher in unvaccinated participants (PR = 1.23, 95%CI: 1.06; 1.42), in those with chronic conditions (PR = 1.13, 95%CI: 1.04; 1.24), and in those who were hospitalized due to the COVID-19 infection (PR = 1.24, 95%CI: 1.16; 1.32). This prevalence was also higher in women (PR = 1.21, 95%CI: 1.09; 1.33) than in men. Physical activity was associated with a reduced likelihood of fatigue, neurological complications, coughing, and headaches as persistent symptoms after a COVID-19 infection. It was found that three out of four adults in Southern Brazil experienced long COVID. Public policies aiming to reduce the burden of long COVID must be prioritized, especially in groups that are at higher risk of developing this harmful condition.

Systematic review and meta-analysis on population attributable fraction for physical inactivity to dementia.

INTRODUCTION: The number of cases of dementia attributable to physical inactivity remains unclear due to heterogeneity in physical inactivity definitions and statistical approaches used. METHODS: Studies that used population-based samples to estimate the population attributable fraction (PAF) of physical inactivity for dementia were included in this review. Weighted PAFs were adjusted for communality among the risk factors (i.e., inactive persons may also share other risk factors) analyzed. Values were reported as percentage (%) of cases of dementia attributable to physical inactivity. RESULTS: We included 22 studies. The overall impact of physical inactivity, defined by any criteria, on dementia ranged from 6.6% (95% CI: 3.6%, 9.6%; weighted) to 16.6% (95% CI: 14.4%, 18.9%; unweighted). Studies using the WHO criterion for physical inactivity estimated a higher unweighted impact (ß = 7.3%; 95% CI: 2.0%, 12.6%) than studies using other criteria. DISCUSSION: Conservatively, one in 15 cases of dementia may be attributable to physical inactivity, defined by any criteria.

The association of aerobic and muscular fitness with cognitive impairment: Findings from a nationally representative survey.

This study aimed to characterize the combined association between cardiorespiratory fitness (CRF), muscular strength, and cognitive outcomes in middle-aged and older adults from low and middle-income countries (LMICs). We analyzed cross-sectional, population-based data from adults aged 50 years or older from six LMICs. Mild cognitive impairment (MCI) was defined according to the National Institute on Aging-Alzheimer's Association criteria. Estimated CRF (eCRF) was calculated using previously validated, sex-specific equations. Handgrip strength (HS) was used as an indicator of muscular strength. We used linear and robust Poisson regression models to examine the associations between eCRF, HS, and MCI. Data from 28,339 adults (63.1 [9.5] years) were analyzed. Participants with low eCRF (PR: 1.45; 95%CI: 1.11, 1.90) and HS (PR: 1.92; 95%CI: 1.79, 2.04) were more prone to have MCI. Participants with low HS showed higher likelihood of MCI than those with preserved HS through the CRF range; however, this difference was not seen among highly fit individuals (10 METs or higher). Each 1-MET (PR: 0.77; 95%CI: 0.67, 0.86) and 5-kgf (PR: 0.63; 95%CI: 0.48, 0.79) increase was associated with a reduction in the likelihood of MCI. eCRF and HS were strongly and independently associated with MCI in middle-aged and older adults.

Care seek behavior for low back pain in southern Brazil during the COVID-19 pandemic: a panel data analysis.

BACKGROUND: During the COVID-19 pandemic, people with low back pain (LBP) might have avoided seeking care for their pain. We aimed to investigate how the COVID-19 pandemic has affected LBP care seeking behavior among adults. METHODS: Data from four assessments of the PAMPA cohort were analyzed. Participants who reported experiencing LBP during wave one both before and during social restrictions (n = 1,753 and n = 1,712, respectively), wave two (n = 2,009), and wave three (n = 2,482) were included. We asked participants about sociodemographic, behavioral, and health factors and outcomes related to LBP. Poisson regression analyses were conducted, and data are presented as prevalence ratios (PR) and respective 95% confidence interval (95%CI). RESULTS: Overall, care seeking behavior decreased by half in the first months of restrictions, from 51.5% to 25.2%. Although there was an increase in care seeking behavior observed in the other two assessments (nearly 10 and 16 months after restrictions), it was insufficient to reach pre-pandemic levels. In the first months of restrictions, a similar scenario was observed for specific care, such as general practitioner and exercise professional care, with proportions of pre-pandemic levels reached after 10 and 16 months. Women were more likely to seek care for LBP 10 and 16 months after restrictions (PR 1.30 95%CI 1.11; 1.52, PR 1.22 95%CI 1.06; 1.39, respectively). Also, those participants who worked, were physically active, and reported pain-related disability and high pain levels were more likely to seek care at all time points assessed. CONCLUSION: Overall, care-seeking behavior for LBP significantly decreased in the first months of restrictions and increased in the following months; however, this behavior remained lower than pre-pandemic levels.

High-velocity resistance training improves executive function in mobility-limited older adults.

OBJECTIVES: To examine the effect of high-velocity resistance training (HVRT) on the executive function of middle-aged and older adults with and without mobility limitations. METHODS: Participants (n = 41, female: 48.9%) completed a supervised 12-week HVRT intervention (2 sessions/week; at 40-60% of one-repetition maximum). The sample included 17 middle-aged adults (40-55 years); 16 older adults (>60 years) and 8 mobility-limited older adults (LIM). Executive function was assessed before and after the intervention period and was reported as z-scores. Maximal dynamic strength, peak power, quadriceps muscle thickness, maximal isometric voluntary contraction (MVIC), and functional performance were also measured pre and post intervention. Training-related adaptations in cognitive measures were calculated using a Generalized Estimating Equation model. RESULTS: HVRT improved executive function in LIM (adjusted marginal mean differences [AMMD]: 0.21; 95%CI: 0.04, 0.38; p = 0.040) although no effect on middle-aged (AMMD: 0.04; 95%CI: -0.09; 0.17; p = 0.533) and older (AMMD: -0.11; 95%CI: -0.25; 0.02; p = 0.107) participants was observed. Improvements in maximal dynamic strength, peak power, MVIC, quadriceps muscle thickness, and functional performance were all associated with changes in executive function, and changes in the first four also seem to mediate the association between changes in functional performance and executive function. CONCLUSIONS: HVRT-induced improvement in executive function of mobility-limited older adults were mediated by changes in lower-body muscle strength, power, and muscle thickness. Our findings reinforce the relevance of muscle-strengthening exercises to preserve cognition and mobility in older adults.

Association of Sleep Duration and Use of Sleeping Medication with Multimorbidity in Adults: Results from the PAMPA (Brazil) Cohort Study.

Objective To analyze the association of sleep duration and use of sleeping medication with multimorbidity. Materials and Methods We conducted a cross-sectional study using data from the Prospective Study about Mental and Physical Health (PAMPA) cohort. Multimorbidity was defined as the presence of two or more conditions from a list of twelve health problems. Descriptive analyses were performed considering proportion and its 95% confidence interval (95%CI). We performed logistic regression (to obtain odds ratios, ORs) to estimate the associations, including models adjusted for confounding factors. Results In total, 2,936 participants were included, 79,1% of them women, 54.2% aged between 18 and 39 years, and 88.9% with white skin color. Compared with regular sleep (seven to eight hours a day), five hours or less of sleep increased the odds of multimorbidity by 145% (95%CI: 1.90-3.14), and 9 hours or more of sleep increased the odds by 49% (95%CI: 1.14-1.95) for the crude model; the results remained significant even in the adjusted models. Discussion Consumption of sleeping medication was associated with multimorbidity. Short and prolonged sleep duration increased the odds of multimorbidity, regardless of the sociodemographic and behavior characteristics. The regular use of sleeping medication was also associated with multimorbidity. The results of the present study are important but require caution due to reverse causality, and longitudinal studies are needed to confirm the findings.

Incidence of memory complaints during the COVID-19 pandemic in Southern Brazil: findings from PAMPA cohort.

Population-level studies investigating the incidence of memory complaints during the COVID-19 pandemic are scarce. Objective: This study aimed to examine the incidence of memory complaints over 15 months during the COVID-19 pandemic in adults from Southern Brazil. Methods: Data from the PAMPA (Prospective Study about Mental and Physical Health in Adults) cohort, a longitudinal study with adults residing in Southern Brazil, were analyzed. An online-based, self-administered questionnaire was used to assess self-rated memory. Participants rated their memories as excellent, very good, good, fair, or poor. Incident memory complaints were defined as worse memory perception from baseline to follow-up. Cox proportional hazard models were used to identify factors associated with the increased risk of memory complaints. Results: During follow-up, a cumulative incidence of 57.6% for memory complaints was observed. Female sex (hazard ratio [HR] 1.49; 95% confidence intervals [CI] 1.16-1.94), lack of access to prescribed medicine (HR: 1.54; 95%CI 1.06-2.23), and worsened anxiety symptoms (HR: 1.81; 95%CI 1.49-2.21) were associated with an increased risk of memory complaints. Regular practice of physical activity was associated with a reduced risk of memory complaints (HR: 0.65; 95%CI 0.57-0.74). Conclusion: Since the COVID-19 pandemic, 6 in 10 adults in Southern Brazil have developed memory complaints. Factors including sex and lack of medications increased the risk of incident memory complaints. Physical activity reduced the risk of incident memory complaints during the COVID-19 pandemic.

Estudos em nível populacional que investiguem a incidência de queixa na memória durante a pandemia de COVID-19 são escassos. Objetivo: Nosso objetivo foi examinar a incidência de queixa na memória, ao longo de 15 meses durante a pandemia de COVID-19, em adultos do Sul do Brasil. Métodos: Foram analisados dados da coorte Estudo Prospectivo sobre Saúde Mental e Física em Adultos (PAMPA), um estudo longitudinal com adultos residentes no Sul do Brasil. Um questionário autoadministrado online foi usado para avaliar a memória autorreferida. Os participantes classificaram sua memória como excelente, muito boa, boa, regular ou ruim. A queixa na memória incidente foi definida como pior percepção de memória desde a linha de base até o acompanhamento. Modelos de risco proporcional de Cox foram usados para identificar fatores associados ao aumento do risco de queixa na memória incidente. Resultados: Durante o seguimento, observou-se incidência cumulativa de 57,6% para queixa na memória. Sexo feminino (hazard ratio ­ HR 1,49; intervalo de confiança ­ IC 95% 1,16­1,94), falta de acesso ao medicamento prescrito (HR: 1,54; IC95% 1,06­2,23) e sintomas de ansiedade (HR: 1,81; IC95% 1,49­2,21) foram associados a risco aumentado de queixa na memória incidente. A prática regular de atividade física foi vista como fator protetor (HR: 0,65; IC95% 0,57­0,74). Conclusões: Desde a pandemia de COVID-19, seis em cada dez adultos no Sul do Brasil desenvolveram queixa na memória. Fatores como sexo e falta de medicamentos aumentaram o risco de queixa na memória incidente. A atividade física reduziu o risco de queixa na memória incidente durante a pandemia de COVID-19.

Effects of exercise training on inflammatory, neurotrophic and immunological markers and neurotransmitters in people with depression: A systematic review and meta-analysis.

BACKGROUND: Major depressive disorder is the most common type of mental disorder. The biological pathway by which exercise promotes its antidepressant effects remains uncleared. This study aimed to systematically review the chronic effect of exercise on blood biomarkers and its association with changes in depressive symptoms in adults with major depressive disorder. METHODS: Randomized controlled trials (RCT) published until February 2020 were screened in seven databases. Studies were systematically reviewed by two independent reviewers. Random effect meta-analysis was performed and reported as standardized mean differences (SMD) and 95 % confidence interval (CI). The meta- analysis protocol was registered with PROSPERO (CRD42021221177). RESULTS: From 3865 records, 12 studies (N = 757 participants, mean age [SD]: 43.0 [11.0], 66.2 % women) were included in this review. Exercise training resulted in superior increase in circulating BDNF (SMD: 0.44, 95%CI: 0.15, 0.73) and kynurenine (SMD: 0.29, 95%CI: 0.04, 0.54), and decrease depressive symptoms (SMD: -0.72, 95%CI: -1.08, -0.37) in adults with major depression disorder compared to control groups. Multivariate meta-regression analysis showed that improvements in circulating levels of BDNF, kynurenine and interleukyn-6 were associated with decreases in depressive symptoms. LIMITATIONS: Results were not stratified by the type of medication used by participants due to the lack of reporting of the included studies. Few studies provided data on other biomarkers (e.g., TNF-α and IL-10) besides BNDF and kynurenine. CONCLUSIONS: Antidepressant effect of exercise may be triggered by improved circulating levels of BNDF, kynurenine, and interleukine-6 in adults with major depressive disorder.

Short-term impact of COVID-19 pandemic on low back pain: data from the PAMPA Cohort, Brazil.

BACKGROUND: To evaluate the short-term impact of COVID-19 pandemic on low back pain (LBP) outcomes in southern Brazil. METHODS: Data from the PAMPA Cohort were analyzed. Adults were recruited between June and July 2020 in the Rio Grande do Sul state using online-based strategies. Participants responded a self-reported, online questionnaire on LBP with two timepoints: before (retrospectively) and during COVID-19 pandemic. We assessed LBP experience, LBP-related activity limitation (no/yes), and LBP intensity (0 to 10 [strongest pain]). RESULTS: From a total sample of 2,321 respondents (mean age: 37.6 ± 13.5; 75.4% women), the prevalence of LBP did not change significantly from before (74.7% [95%CI 72.3; 76.9]) to the first months of pandemic (74.2% [95%CI 71.9; 76.3]). However, an increased pain levels (ß: 0.40; 95%CI 0.22; 0.58) and a higher likelihood for activity limitation due to LBP was observed (PR 1.14; 95%CI 1.01; 1.29). Longitudinal analyzes showed that age, gender, BMI, chronic diseases, physical activity, and anxiety and depression symptoms, were associated with LBP in the first pandemic months. CONCLUSION: Although the prevalence of LBP did not change at the first months of COVID-19 pandemic, LBP-induced impairment in daily activities and pain intensity was higher when compared to before the pandemic.

Chronic low back pain prevalence in Federal Highway Police Officers: A cross-sectional study.

BACKGROUND: Police officers are exposed to specific occupational tasks, which require lifting, trunk flexion and rotation, carrying weight, and frequent standing periods, which may be associated with an increased risk of experiencing low back pain (LBP). OBJECTIVE: To describe the prevalence and intensity of chronic LBP (CLBP) in Brazilian Federal Highway Police officers (FHPO) from the Rio Grande do Sul state and evaluate its associated factors. METHODS: A total of 208 FHPOs participated in this study. The participants answered an electronic questionnaire containing sociodemographic, behavioral, and occupational questions, and CLBP history. Data analysis comprises descriptive statistics and Poisson regression models. RESULTS: Most of the FHPO were male, aged 41 or more, lived with a partner and were physically active. Sixty-seven percent of FHPO had CLBP, and the median pain intensity was 3.0 (IQR = 0- 5). Participants who lived with a partner were less likely to report CLBP (PR = 0.80; 95% CI = 0.64; 0.99). On the other hand, those who worked as FHPO for more than 11 years were more likely to report CLPB (PR = 1.32; 95% CI = 1.06; 1.63), and high pain intensity (ß= 0.95; 95% CI = 0.19; 1.71). CONCLUSIONS: The high CLBP prevalence among FHPO from Rio Grande do Sul state indicates a need to highlight the importance for police organizations to promote CLBP prevention and implement workplace management programs.

Prevalence and factors associated with long COVID in adults from Southern Brazil: findings from the PAMPA cohort / Prevalência e fatores associados à COVID longa em adultos do Sul do Brasil: achados da coorte PAMPA / Prevalencia y factores asociados con el COVID largo en adultos del Sur de Brasil: hallazgos de la cohorte PAMPA

Abstract: Most COVID-19 survivors have reported experiencing persistent symptoms after the infection - these types of cases are known as long COVID. Since Brazil was an epicenter of the COVID-19 pandemic, a high burden of long COVID is expected. This study aimed to identify the prevalence and factors associated with long COVID in adults in Southern Brazil, analyzing data from the PAMPA cohort. Participants filled out a self-reported online questionnaire in June 2022. This study only included subjects who tested positive for COVID-19. Long COVID was defined by any symptoms that persisted for at least three months after the SARS-CoV-2 infection. Poisson's regression models with robust variance were used to identify factors associated with long COVID; and results were reported as prevalence ratios (PR) and respective 95% confidence intervals (95%CI). A total of 1,001 participants (77.4% women, mean age [SD] = 38.3 [11.9] years) were analyzed. The prevalence of long COVID among these patients was 77.4% (95%CI: 74.7; 79.9). The likelihood of long COVID was higher in unvaccinated participants (PR = 1.23, 95%CI: 1.06; 1.42), in those with chronic conditions (PR = 1.13, 95%CI: 1.04; 1.24), and in those who were hospitalized due to the COVID-19 infection (PR = 1.24, 95%CI: 1.16; 1.32). This prevalence was also higher in women (PR = 1.21, 95%CI: 1.09; 1.33) than in men. Physical activity was associated with a reduced likelihood of fatigue, neurological complications, coughing, and headaches as persistent symptoms after a COVID-19 infection. It was found that three out of four adults in Southern Brazil experienced long COVID. Public policies aiming to reduce the burden of long COVID must be prioritized, especially in groups that are at higher risk of developing this harmful condition.

Resumo: A maior parte dos sobreviventes da COVID-19 relatou sintomas persistentes após a infecção, também conhecida como COVID longa. O Brasil foi um epicentro da pandemia de COVID-19, logo, espera-se uma alta carga de COVID longa. Este estudo teve como objetivo identificar a prevalência e os fatores associados à COVID longa em adultos no Sul do Brasil. Foram analisados dados da coorte PAMPA. Os participantes preencheram um questionário online autoaplicável em junho de 2022. Foram incluídos apenas os participantes que testaram positivo para COVID-19. A COVID longa foi definida como qualquer sintoma que persistiu por pelo menos três meses após a infecção do SARS-CoV-2. Os modelos de regressão de Poisson com variância robusta foram usados para identificar fatores associados à COVID longa; os resultados foram relatados como razão de prevalência (RP) e seus respectivos intervalos de 95% de confiança (IC95%). Ao todo, 1.001 participantes (77,4% mulheres, idade média [DP] = 38,3 [11,9] anos) foram analisados. A prevalência da COVID longa foi de 77,4% (IC95%: 74,7; 79,9). A probabilidade da COVID longa foi maior em participantes não vacinados (RP = 1,23, IC95%: 1,06; 1,42), pessoas com condições crônicas (RP = 1,13, IC95%: 1,04; 1,24), e pacientes hospitalizados devido à infecção por COVID-19 (RP = 1,24, IC95%: 1,16; 1,32) em comparação com as contrapartes. A prevalência foi maior em mulheres (RP = 1,21, IC95%: 1,09; 1,33) do que em homens. A atividade física foi associada à probabilidade reduzida de fadiga, complicações neurológicas, tosse e dor de cabeça como sintomas persistentes após a infecção por COVID-19. Três em cada quatro adultos no Sul do Brasil tiveram COVID longa. Políticas públicas que visem reduzir a carga da covid longa devem ser priorizadas, especialmente nos grupos de maior risco desta condição.

Resumen: La mayoría de los supervivientes de la COVID-19 relató síntomas persistentes tras la infección, también conocida como COVID largo. Brasil fue un epicentro de la pandemia de COVID-19, así, se espera una alta carga de COVID largo. El objetivo de este estudio fue identificar la prevalencia y los factores asociados con la COVID largo en adultos en el Sur de Brasil. Se analizaron datos de la cohorte PAMPA. Los participantes rellenaron un cuestionario en línea autoadministrado en junio de 2022. Solo se incluyeron los participantes que dieron positivo para COVID-19. La COVID largo fue definida como cualquier síntoma que persistió durante al menos tres meses tras la infección del SARS-CoV-2. Se utilizaron los modelos de regresión de Poisson con varianza robusta para identificar factores asociados con el COVID largo; se relataron los resultados como razón de prevalencia (RP) y sus respectivos intervalos de 95% confianza de 95% (IC95%). En total, se analizaron 1.001 participantes (el 77,4% mujeres, edad media [DP] = 38,3 [11,9] años). La prevalencia del COVID largo fue del 77,4% (IC95%: 74,7; 79,9). La probabilidad del COVID largo fue más alta en participantes no vacunados (RP = 1,23, IC95%: 1,06; 1,42), personas con condiciones crónicas (RP = 1,13, IC95%: 1,04; 1,24) y pacientes hospitalizados debido a la infección por COVID-19 (RP = 1,24, IC95%: 1,16; 1,32) en comparación con sus contrapartes. La prevalencia fue más alta en mujeres (RP = 1,21, IC95%: 1,09; 1,33) que en hombres. La actividad física se asoció con la probabilidad reducida de fatiga, complicaciones neurológicas, tos y dolor de cabeza como síntomas persistentes tras la infección por COVID-19. Tres de cada cuatro adultos en el Sur de Brasil han tenido COVID largo. Se deben priorizar las políticas públicas destinadas a reducir la carga del COVID largo, sobre todo en los grupos de mayor riesgo para esta condición.

Incidence of memory complaints during the COVID-19 pandemic in Southern Brazil: findings from PAMPA cohort / Incidência de queixas de memória durante a pandemia de COVID-19 no sul do Brasil: dados da coorte PAMPA

ABSTRACT. Population-level studies investigating the incidence of memory complaints during the COVID-19 pandemic are scarce. Objective: This study aimed to examine the incidence of memory complaints over 15 months during the COVID-19 pandemic in adults from Southern Brazil. Methods: Data from the PAMPA (Prospective Study about Mental and Physical Health in Adults) cohort, a longitudinal study with adults residing in Southern Brazil, were analyzed. An online-based, self-administered questionnaire was used to assess self-rated memory. Participants rated their memories as excellent, very good, good, fair, or poor. Incident memory complaints were defined as worse memory perception from baseline to follow-up. Cox proportional hazard models were used to identify factors associated with the increased risk of memory complaints. Results: During follow-up, a cumulative incidence of 57.6% for memory complaints was observed. Female sex (hazard ratio [HR] 1.49; 95% confidence intervals [CI] 1.16-1.94), lack of access to prescribed medicine (HR: 1.54; 95%CI 1.06-2.23), and worsened anxiety symptoms (HR: 1.81; 95%CI 1.49-2.21) were associated with an increased risk of memory complaints. Regular practice of physical activity was associated with a reduced risk of memory complaints (HR: 0.65; 95%CI 0.57-0.74). Conclusion: Since the COVID-19 pandemic, 6 in 10 adults in Southern Brazil have developed memory complaints. Factors including sex and lack of medications increased the risk of incident memory complaints. Physical activity reduced the risk of incident memory complaints during the COVID-19 pandemic.

RESUMO. Estudos em nível populacional que investiguem a incidência de queixa na memória durante a pandemia de COVID-19 são escassos. Objetivo: Nosso objetivo foi examinar a incidência de queixa na memória, ao longo de 15 meses durante a pandemia de COVID-19, em adultos do Sul do Brasil. Métodos: Foram analisados dados da coorte Estudo Prospectivo sobre Saúde Mental e Física em Adultos (PAMPA), um estudo longitudinal com adultos residentes no Sul do Brasil. Um questionário autoadministrado online foi usado para avaliar a memória autorreferida. Os participantes classificaram sua memória como excelente, muito boa, boa, regular ou ruim. A queixa na memória incidente foi definida como pior percepção de memória desde a linha de base até o acompanhamento. Modelos de risco proporcional de Cox foram usados para identificar fatores associados ao aumento do risco de queixa na memória incidente. Resultados: Durante o seguimento, observou-se incidência cumulativa de 57,6% para queixa na memória. Sexo feminino (hazard ratio — HR 1,49; intervalo de confiança — IC 95% 1,16-1,94), falta de acesso ao medicamento prescrito (HR: 1,54; IC95% 1,06-2,23) e sintomas de ansiedade (HR: 1,81; IC95% 1,49-2,21) foram associados a risco aumentado de queixa na memória incidente. A prática regular de atividade física foi vista como fator protetor (HR: 0,65; IC95% 0,57-0,74). Conclusões: Desde a pandemia de COVID-19, seis em cada dez adultos no Sul do Brasil desenvolveram queixa na memória. Fatores como sexo e falta de medicamentos aumentaram o risco de queixa na memória incidente. A atividade física reduziu o risco de queixa na memória incidente durante a pandemia de COVID-19.

Knee, low back and disabling pain and their associated factors in instructors of gym clubs: a census study / Fatores associados às dores no joelho, na lombar e incapacitante em instrutores de academias de ginástica: um estudo censitário

Abstract Background Although gym club instructors are closely linked to health and well-being, this group of workers shows specific characteristics that may favor the involvement in musculoskeletal disorders in their occupational routines. Objective To identify the prevalence of knee, low back, and disabling pain and their association with sociodemographic, nutritional, and occupational variables in instructors from gym clubs in the city of Pelotas, southern Brazil. Method A census-type study was carried out with all professionals working at gym clubs (n=497). Crude and multivariable analyses were performed considering "sex", "age", "income", "occupational physical activity", "time working at the gym clubs" and "modality performed" as exposures. Outcomes were disabling pain, and knee and low back pain. Results The disabling pain affected 20.9% of the workers and was associated with the gym clubs modality performed and with the working longest time in the gym clubs. Half of the professionals related to low back pain in the previous year. This outcome was associated with the age (inversely), of females and Pilates instructors. The knee pains affected, in the last year, 41.5% of the professionals; there was a significant association between age (inversely) and time of work in the gym clubs. Conclusion The instructors had a high prevalence of the three outcomes analyzed. Those who have been working longer time at gym clubs, women, youngers, Pilates, or gymnastic instructors were at an increased risk of presenting the outcomes.

Resumo Introdução Embora os instrutores de academias de ginástica estejam ligados à saúde e ao bem-estar, esse grupo de trabalhadores apresenta características específicas que podem favorecer o surgimento de distúrbios osteomusculares em suas rotinas ocupacionais. Objetivo Verificar a prevalência de dor no joelho, dor lombar e dor incapacitante e sua associação com variáveis sociodemográficas, nutricional e ocupacionais em instrutores de academias de ginástica da cidade de Pelotas, Brasil. Método Censo realizado com todos os profissionais atuantes nas academias da cidade (n=497). Foi realizada análise bruta e ajustada (regressão de Poisson), considerando as variáveis de exposição "sexo", "idade", "renda", "atividade física ocupacional", "anos de trabalho como profissional de academia" e "modalidade ministrada". As variáveis desfecho foram dor no joelho, dor lombar e dor incapacitante. Resultados A dor incapacitante acometeu 20,9% dos profissionais e esteve associada com a função de ministrar aulas de ginástica e com o maior tempo de trabalho em academia. Metade dos entrevistados referiu sentir dor lombar no último ano, sendo associado à idade (inversamente), ao sexo feminino e ministrar aulas de Pilates. A dor no joelho acometeu, no último ano, 41,5% dos profissionais, havendo associação significativa com a idade (inversamente) e o tempo de trabalho em academia. Conclusão Conclui-se que os instrutores das academias de ginástica tiveram uma alta prevalência dos três desfechos analisados. O tempo de trabalho em academia, o sexo feminino, idade, profissionais de Pilates e de ginástica estiveram associados com maiores prevalências das dores investigadas.

Physical activity and the incidence of depression during the COVID-19 pandemic in Brazil: Findings from the PAMPA cohort.

We examined the longitudinal association between physical activity (PA) and the incidence of self-reported diagnosed depression in adults in southern Brazil during the COVID-19 pandemic. Data from the PAMPA (Prospective Study About Mental and Physical Health) cohort was used. Data collection for baseline was carried out on June-July 2020, with two follow-up assessments taking place six months apart. An online, self-reported questionnaire assessed depression and PA. Depression was assessed by asking participants whether they were ever diagnosed with depression. We included 441 participants (women: 75.9%; mean age [SD]: 38.0 [13.5]) in southern Brazil. Over the follow-up, 21.8% (95% confidence interval [CI]: 18.1%-25.9%) were diagnosed with depression. Insufficiently active (<150 min per week of physical activity) (Incidence rate [IR]: 61.9; 95%CI: 39.5-102.4; p = 0.047) and active (≥150 min per week of physical activity) (IR: 50.4; 95%CI: 31.9-84.0; p = 0.015) participants had reduced IR of depression per 1000 persons-year at risk compared to inactive ones (0 min per week of physical activity) (IR: 99.9; 95%CI: 79.7-126.8). In the adjusted analyses, participants in the insufficient active (hazard ratio [HR]: 0.58; 95%CI: 0.34-0.98) and active (HR: 0.53; 95%CI: 0.31-0.93) group had a lower risk of developing depression than the inactive group. PA both at and out of home reduced the risk of incident depression (HR: 0.49; 95%CI: 0.25-0.98) compared to no physical activity. Endurance (HR: 0.52; 95%CI: 0.28-0.97) and endurance plus strengthening (HR: 0.40; 95%CI: 0.17-0.95) PA reduced the risk of incident depression compared to none. Being physically active during pandemic, regardless of the amount of PA practiced, reduced the incidence of depression in adults in southern Brazil.
