BACKGROUND: The objective of this study was to investigate gender differences in authorship in physical activity and health research. METHODS: A bibliometric study including 23,399 articles from 105 countries was conducted to estimate the participation of female researchers in physical activity publications from 1950 to 2019. The frequency of female researchers was analyzed and classified by first and last authors and the overall percentage of female authors by region and country. RESULTS: The proportion of female first authors increased from <10% in the 50s and 80s to 55% in the last decade. On the other hand, the proportion of last authors increased from 8.7% to 41.1% in the same period. Most publications with female researchers were from the United States, Canada, Australia, Brazil, the Netherlands, Spain, England, Germany, Sweden, and China. Nine of these countries had over 50% of the articles published by female first authors. However, in all 10 countries, <50% of the articles were published by female last authors. CONCLUSIONS: The proportion of female researchers increased over time. However, regional differences exist and should be addressed in gender equity policies. There is a gap in the participation of female researchers as last authors. By actively addressing the gender gap in research, the global society can harness the full potential of all talented individuals, regardless of gender, leading to more inclusive and impactful scientific advancements.

This study aimed to analyze the physical activity trend of Brazilian schoolchildren and the associations with demographic, socioeconomic, and behavioral variables by using the Brazilian National Survey of School Health (PeNSE) in its four editions - 2009, 2012, 2015, and 2019. Data from students (13-17 years old) participating in the four editions of the PeNSE (n = 392,922) were used. We describe the percentage of active, mean, and percentile values of moderate to vigorous intensity physical activity in minutes/week. Poisson's regression was adjusted for gender, age, skin color, goods score, and sedentary behavior (≥ 2 hours/day watching TV and ≥ 3 hours/day sitting time). As a limitation, the PeNSE/2009 sample refers only to the Brazilian capital cities. The percentage of active students decreased from 43.1% in 2009 to 18.2% in 2019. The mean moderate to vigorous intensity physical activity of PeNSE/2009 (mean = 318.4 minutes/week; 95%CI: 313.4-323.4) decreased 50% in 2019. In physical education, the weekly average in moderate to vigorous intensity physical activity of girls is less than 50 minutes and boys is greater than 60 minutes in the four editions of PeNSE, also 22.7% of girls reported (PeNSE/2019) not having taken physical education classes whereas the same thing is reported by 19.7% of boys. Sedentary behavior reduced regarding time watching TV, but sitting time increased by 50.1% (95%CI: 48.9-51.3) and 54% (95%CI: 53.1-54.9) between PeNSE/2009 and PeNSE/2019. As a consequence of the drop in physical activity levels, public policies that promote physical activity are necessary, including increasing physical education classes at school to at least three times a week.
O objetivo do estudo foi analisar a tendência de atividade física dos escolares brasileiros e as associações com variáveis demográficas, socioeconômicas e comportamentais, por meio da Pesquisa Nacional de Saúde do Escolar (PeNSE) em suas quatro edições - 2009, 2012, 2015 e 2019. Foram usados dados dos escolares (13-17 anos) participantes das quatro edições da PeNSE (n = 392.922). Descrevemos o percentual de ativos, a média e valores percentuais da atividade física de intensidade moderada à vigorosa em minutos/semana. A regressão de Poisson foi ajustada para sexo, idade, cor da pele, escore de bens e comportamento sedentário (≥ 2 horas/dia para assistir TV e ≥ 3 horas/dia de tempo sentado). Como limitação, a amostra da PeNSE/2009 refere-se apenas às capitais brasileiras. O percentual de ativos reduziu de 43,1% em 2009 para 18,2% em 2019. A média em atividade física de intensidade moderada à vigorosa da PeNSE/2009 (média = 318,4 minutos/semana; IC95%: 313,4-323,4) reduziu 50% em 2019. Na educação física, a média semanal em atividade física de intensidade moderada à vigorosa das meninas foi menor que 50 minutos, ao passo que a dos meninos foi maior que 60 minutos, nas quatro edições da PeNSE. Ainda, 22,7% das meninas relataram (PeNSE/2019) não ter tido aulas de educação física, enquanto o mesmo é relatado por 19,7% dos meninos. O comportamento sedentário sofreu redução no hábito de assistir TV, porém o tempo sentado aumentou de 50,1% (IC95%: 48,9-51,3) para 54% (IC95%: 53,1-54,9) entre a PeNSE/2009 e a PeNSE/2019. Como consequência da queda nos níveis de atividade física, são necessárias políticas públicas que promovam a atividade física, como aumentar as aulas de educação física na escola para, no mínimo, três vezes por semana.
El objetivo de este estudio fue analizar la tendencia de la actividad física del alumnado brasileño y sus asociaciones con las variables demográficas, socioeconómicas y de comportamiento mediante la Encuesta Nacional de Salud del Escolar (PeNSE) en sus cuatro ediciones (de 2009, 2012, 2015 y 2019). Se utilizaron los datos del alumnado (13-17 años) que participó en las cuatro ediciones de la PeNSE (n = 392.922). Se describieron el porcentaje de valores activos, la media y los valores percentiles de actividad física de intensidad moderada a vigorosa en minutos/semana. La regresión de Poisson se ajustó según sexo, edad, color de la piel, puntuación de activos y comportamiento sedentario (≥ 2 horas/día para ver televisión y ≥ 3 horas/día sentado). Como limitación, la muestra de la PeNSE/2009 se refiere únicamente a las capitales brasileñas. El porcentaje de activos disminuyó del 43,1% en 2009 al 18,2% en 2019. La media de actividad física de intensidad moderada a vigorosa de la PeNSE/2009 (media = 318,4 minutos/semana; IC95%: 313,4-323,4) tuvo una reducción de un 50% en 2019. En educación física, el promedio semanal en actividad física de intensidad moderada a vigorosa de las niñas fue menos de 50 minutos, y el de los niños llegó a 60 minutos en las cuatro ediciones de la PeNSE, además, el 22,7% de las niñas y el 19,7% de los niños (PeNSE/2019) informaron no haber tomado clases de educación física. Hubo una disminución en el comportamiento sedentario de ver televisión, pero el tiempo sentado aumentó del 50,1% (IC95%: 48,9-51,3) al 54% (IC95%: 53,1-54,9) entre la PeNSE/2009 y la PeNSE/2019. El descenso de los niveles de actividad física lleva a la necesidad de desarrollar políticas públicas que promuevan la actividad física, incluido el incremento de las clases de educación física en las escuelas al menos tres veces por semana.

OBJECTIVES: The aim of this study was to investigate the effect of maternal's depression trajectory in the first 1000 days of the child's life on the prevalence of early childhood dental caries (ECC), in a birth cohort. MATERIALS AND METHODS: All infants born in Pelotas in 2015 were identified, and the mothers were invited to participate in the cohort. A total of 3645 children were included in the study. The outcome was ECC at 48 months of age assessed according to ICDAS. Maternal depression was collected using Edinburgh Postnatal Depression Scale (EPDS) antenatally, at 3, 12, and 24 months of age. Maternal depressive symptom trajectory variables were created using group-based trajectory models and adopting two cutoff points. Poisson regression model with robust variance was used to identify the total effect of maternal depressive symptom trajectories on ECC, adjusting by confounders. RESULTS: A total of 29.2% of the mothers presented a high trajectory for screening of depression, and 18.8% presented a high trajectory of depression diagnosis. The prevalence of ECC was 26.7%. After adjusted analysis, maternal depression trajectories (screening and diagnosis) from pregnancy to 24 months increased the risk for ECC at 48 months of age (RR = 1.14; 95% CI 1.02-1.28 and RR = 1.19; 95% CI 1.05-1.35). CONCLUSIONS: Children from mothers with high depression trajectory had higher risk of having dental caries at 48 months compared to children from mothers with low depression trajectory. CLINICAL RELEVANCE: Strategies of early detection and treatment of maternal mental disorders during the Golden Period should be considered of high priority in health services since it could impact positively in children's life.

BACKGROUND: Motherhood has been associated with reduced leisure-time physical activity (LTPA) levels. We aim to assess maternal LTPA patterns from preconception to 4 years postpartum. METHODS: The study was developed with mothers from the Pelotas 2015 Birth Cohort, Southern Brazil (n = 4273). LTPA data were self-reported for preconception, antenatal, and 3, 12, 24, and 48 months postpartum. Information on LTPA referring to preconception (3 mo before pregnancy) and each gestational trimester was retrospectively collected in perinatal. The prevalence of active mothers was calculated according to recommendations (≥150 min/wk). We described changes in LTPA between follow-ups and estimated the probability of mothers being active according to previous LTPA. We used group-based trajectory analysis to identify patterns of LTPA throughout the follow-ups. RESULTS: The prevalence of active mothers during leisure time decreased in pregnancy and postpartum compared with preconception. At 12 months postpartum, LTPA levels rose again, but at 48 months, the rates of active mothers still had not returned to preconception levels. Prior LTPA engagement was an important determinant of the maintenance of LTPA. Trajectory analysis identified 4 patterns of maternal LTPA, and â¼80% of mothers were allocated to the "always inactive" group. Higher education and income, working outside the home, multiple births, and participating in the PAMELA study intervention were associated with a higher probability of mothers not being included in this predominantly inactive group. CONCLUSIONS: Motherhood is associated with declining rates of women meeting physical activity recommendations during pregnancy and early postpartum.

BACKGROUND: The association of physical activity through early childhood on children's chronic stress still is unclear. Therefore, the aim of the present study is to test the association of physical activity through early childhood (1-4 y) with chronic stress, measured by hair cortisol at age 4. METHODS: Longitudinal study including children from the 2015 Pelotas (Brazil) Birth Cohort. Cortisol at age 4 was measured using a hair sample, which provided cortisol concentration from the past months. Physical activity was measured using accelerometers at 1, 2, and 4 years. Linear regression models were used to assess the association between physical activity and chronic stress. Trajectory models were also applied to examine chronic stress in relation to physical activity patterns throughout early childhood. RESULTS: Children with valid physical activity and hair cortisol data were included in the analyses (N = 1475). Three groups of physical activity trajectories between 1 and 4 years were identified: low, medium, and high. No association between physical activity at 1, 2, and 4 years and chronic stress at age 4 was observed. However, children in the "high" physical activity trajectory presented low cortisol concentration; the magnitude of the regression coefficient was slightly larger in girls (ß = -0.125; 95% confidence interval, -0.326 to 0.074) than boys (ß = -0.051; 95% confidence interval, -0.196 to 0.09). CONCLUSION: There was no clear association between physical activity and chronic stress in early childhood. Trajectories models suggest that higher activity throughout early childhood may positively impact chronic stress; however, more studies are needed to confirm that hypothesis.

Physical activity for young children provides a wealth of benefits for health and development. However, little is known about the inter-relationship of physical activity and growth indicators. The aim of this study was to test the bi-directional associations of physical activity and growth indicators in children under five years of age. This prospective study included 1,575 children with data on physical activity and growth indicators at ages 12, 24 and 48 months. Accelerometers were used to measure physical activity. Z-scores for length/height-for-age, weight-for-length/height, weight-for-age and body mass index (BMI)-for-age were calculated. Bi-directional associations between physical activity and growth indicators were evaluated using cross-lagged panels based on Generalized Estimating Equations and cross-lagged structural equation models. Physical activity was consistently associated with lower weight-related growth indicators: BMI-for-age: ß=-0.12; Weight-for-age: ß=-0.11; Weight-for-length/height: ß=-0.12. Higher BMI-for-age indicated lower physical activity (ß=-0.06). When the exposure was lagged, the association of physical activity on weight-related growth indicators remained, but weight-related growth indicators showed a negative association on physical activity. A bi-directional association between physical activity and weight-related growth indicators was observed. The magnitude of associations were stronger when physical activity was modelled as exposure. These results reinforce the importance of physical activity since early years.

BACKGROUND: Physical education (PE) classes in schools are considered relevant to implement interventions, especially focused on physical activity. However, evidence overviews on how PE classes contribute to general health (physical, social, affective, and cognitive domains) are still needed. Thus, we summarized evidence synthesis (eg, systematic reviews) that addressed the contribution of PE classes to the health of school-aged children and adolescents. METHODS: We performed a scoping review with searches in 8 databases and institutional websites to find systematic reviews or meta-analyses that answered this review's research question. Data charting form included the identification of the study, health outcomes, and PE classes' strategies (policies and environment, curriculum, appropriate instructions, and evaluation). An interactive process was performed to build the evidence summary. RESULTS: An initial search yielded 2264 titles, and 49 systematic reviews (including 11 with meta-analysis) were included in this review. Most documents reported the main benefits of PE classes on physical domain outcomes (eg, physical activity, cardiorespiratory fitness, body mass index, and fundamental motor skills). However, evidence on the benefits of PE classes in affective (eg, enjoyment, motivation, and autonomy); social (eg, cooperation, problem-solving, and making friends); and cognitive (eg, memory, attention, concentration, and decision making) domains were found. Strategies on PE classes for health benefits were highlighted. CONCLUSIONS: These elements were detailed in the evidence summary, which may be considered to guide researchers, teachers, and practitioners to define research and practice priorities on PE class interventions for health in the school context.

RESUMEN
This prospective cohort study within an open-label, single-arm, phase 4 vaccination trial (clinicaltrials.gov #NCT04754698) aimed to investigate the association between physical activity and persistent anti-SARS-CoV-2 antibodies 6 months after two-dose schedule of CoronaVac in autoimmune rheumatic diseases (ARD) patients (n = 748). Persistent immunogenicity 6 months after the full-course vaccination was assessed using seroconversion rates of total anti-SARS-CoV-2 S1/S2 IgG, geometric mean titers of anti-S1/S2 IgG (GMT), and frequency of positive neutralizing antibodies (NAb). Physical activity was assessed trough questionnaire. Adjusted point estimates from logistic regression models indicated that physically active patients had greater odds of seroconversion rates (OR: 1.5 [95%CI: 1.1 to 2.1]) and NAb positivity (OR: 1.5 [95%CI: 1.0 to 2.1]), and approximately 43% greater GMT (42.8% [95%CI: 11.9 to 82.2]) than inactive ones. In conclusion, among immunocompromised patients, being physically active was associated with an increment in antibody persistence through 6 months after a full-course of an inactivated SARS-CoV-2 vaccine.

The NEPHROS is a randomized controlled trial which applied a 16-week aerobic and resistance training to patients with chronic kidney disease (CKD) and high blood pressure. This report describes a long-term post-trial follow-up, comparing survival, health-related quality of life (HRQoL), and estimated glomerular filtration rate (GFR) change between the intervention and control groups according to in-trial cardiovascular risk factors. Three years after the original trial, NEPHROS participants were re-evaluated. Cox proportional hazards model was used to compare survival time and linear regression for changes in GFR and physical and mental HRQoL summary scores between intervention and control groups according to age, sex, and in-trial GFR, C-reactive protein, glucose, lipids, ankle-brachial index (ABI), functional capacity, and blood pressure. Of the 150 participants of NEPHROS, 128 were included in the long-term analysis. The previous exercise training had no effects on survival, GFR, or HRQoL. Baseline in-trial GFR (HR = 0.95, 95%CI: 0.92; 0.98) and ABI (HR = 0.03, 95%CI: 0.002; 0.43) were positive independent predictors for survival. Lower ABI (coefficient = 9.00, 95%CI: 0.43; 17.5) and higher systolic blood pressure (coefficient = -0.13, 95%CI: -0.24; -0.03) were independent predictors for GFR decline. A 16-week exercise program had no long-term effect on survival, quality of life, or glomerular filtration in patients with CKD stages 2 to 4. Lower GFR and ABI and higher systolic blood pressure were associated with poorer prognosis among CKD patients.

BACKGROUND: Understanding which strategies have been recommended for the promotion of active and healthy lifestyles through physical education (PE) classes can guide PE policies and practice. Therefore, we summarized worldwide recommendations regarding strategies for PE classes that have aimed to promote active and healthy lifestyles among school-aged children and adolescents. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines were utilized. A literature search was carried out in June 2020 in eight peer-reviewed literature databases, in addition to searches in institutional and personal libraries. The eligibility criteria included any online document that included recommendations targeting any dimension of PE classes (e.g., policy and environment, curriculum, appropriate instruction, student assessment, and strategies that interact with PE) published since 2000. RESULTS: In total, 2,408 potentially eligible documents were screened. Of these, 63 were included in the final analysis. The recommended strategies were as follows: six referred to policy and environment (valuing PE, higher frequency and duration of classes, inclusive PE classes, mandatory daily classes, evaluation of PE classes, and qualified teachers), five to curriculum (structure, type of content, cross-cutting themes, and components that improve PE classes), four to appropriate instruction (promotion of physical activities, inclusion of social issues, employment of the use of innovative technologies, and organization of the teaching-learning process), and three to student assessment (understanding human movement concepts, evaluation of contents, and assessment methods to develop an active and healthy lifestyle). CONCLUSION: Twenty-one strategies recommended for PE classes linked to five dimensions aimed at different target populations were identified. Over half were linked to the dimensions of policy and environment and appropriate instruction. PE is recommended to be mandatory and valued at all educational levels, with weekly frequency that contributes to an active and healthy lifestyle. This review shows that guaranteeing different experiences beyond sports, improving social inclusion, using innovative technologies, and providing adequate materials and spaces to be important challenges and ways to guide policies, programs, and new research in this field of knowledge.

BACKGROUND: The aim of this study was to investigate longitudinal associations between physical activity and early childhood neurodevelopment. METHODS: Data from 1673 children from the 2015 Pelotas (Brazil) birth cohort study were analyzed. Physical activity was measured using accelerometers on the wrist at ages 1, 2, and 4 years. Neurodevelopment was measured using the Battelle Development Inventory at age 4 years. Linear regression models were used to test trajectories and cumulative associations of physical activity with child neurodevelopment. RESULTS: Of the 3 physical activity trajectories observed, children in the medium (ß = 1.17; 95% confidence interval, 0.25 to 2.10) and high (ß = 2.22; 95% confidence interval, 0.61 to 3.82) trajectories showed higher neurodevelopment scores than children in the lower activity trajectory. Cumulative analyses showed that children in the highest tertile of physical activity in all follow-ups presented a mean neurodevelopment score 4.57 (95% confidence interval, 2.63 to 6.51) higher than children in the lowest tertile in all follow-ups. All analyses showed a dose-response characteristic of association, with higher physical activity indicating higher neurodevelopment scores. CONCLUSIONS: Physical activity may be an important predictor of neurodevelopment through early childhood.

O estudo NEPHROS é um ensaio controlado e randomizado que aplicou um programa de treinamento aeróbico e de força com duração de 16 semanas em pacientes com doença renal crônica e hipertensão arterial. O artigo descreve o seguimento pós-ensaio de longo prazo, comparando sobrevida, qualidade de vida relacionada à saúde (HRQoL) e mudança na taxa de filtração glomerular estimada (TFGe) entre o grupo de intervenção e o grupo controle, e de acordo com fatores de risco cardiovascular registrados durante o ensaio. Os participantes do estudo NEPHROS foram reavaliados três anos depois do ensaio original. Foi usada a razão de riscos proporcionais de Cox para comparar o tempo de sobrevida, e a regressão linear para comparar a mudança na TFGe e as pontuações gerais de HRQoL física e mental, entre os grupos de intervenção e controle, de acordo com idade, sexo e níveis durante o ensaio original de TFGe, proteína C-reativa, glicose, lipídios, índice tornozelo-braquial (ITB), capacidade funcional e pressão arterial. Entre os 150 participantes do NEPHROS, 128 foram incluídos na análise de seguimento. Não foi observado nenhum efeito do treinamento na sobrevida, TFGe ou HRQoL. As medidas durante o ensaio original de TFGe (HR = 0,95; IC95%: 0,92; 0,98) e ITB (HR = 0,03; IC95%: 0,002; 0,43) foram preditores positivos independentes de sobrevida. ITB mais baixo (coeficiente = 9,00; IC95%: 0,43; 17,5) e pressão sistólica mais alta (coeficiente = -0,13; IC95% -0,24; -0.03) foram preditores independentes de declínio da TFGe. O programa de exercício de 16 semanas não teve efeito no longo prazo sobre sobrevida, qualidade de vida ou mudança na taxa de filtração glomerular em pacientes com doença renal crônica de estágios 2 a 4. Níveis mais baixos de TFGe e ITB e pressão arterial sistólica mais elevada estiveram associados a prior prognóstico entre pacientes com doença renal crônica.
NEPHROS es un ensayo controlado aleatorio que aplicó un entrenamiento de 16 semanas aeróbico y de resistencia a pacientes con enfermedad crónica de riñón y presión alta. El informe actual describe un seguimiento de largo plazo post ensayo, comparando supervivencia, calidad de vida relacionada con la salud (HRQoL) y el cambio de tasa estimada de filtración glomerular (eGFR) entre los grupos de intervención y control, y según factores de riesgo cardiovascular en el ensayo. Tras tres años del ensayo original, los participantes en NEPHROS fueron reevaluados. Se usó el modelo de Cox de riesgos proporcionales para comparar el tiempo de supervivencia y la regresión lineal para comparar el cambio en los marcadores resumen eGFR, físicos y mentales HRQoL, entre los grupos de intervención y grupos de control, y según edad, sexo, y eGFR en el ensayo, proteína C-reactiva, glucosa, lípidos, índice tobillo-brazo (ABI), capacidad funcional y presión sanguínea. De los 150 participantes de NEPHROS, 128 personas fueron incluidas en el análisis a largo plazo. No se observó un cambio en el efecto del entrenamiento físico previo en la supervivencia, eGFR o HRQoL. La base de referencia en el ensayo eGFR (HR = 0,95; 95%CI: 0,92; 0,98) y ABI (HR = 0,03; 95%CI: 0,002; 0,43) fueron predictores independientes positivos para la supervivencia. Un más bajo ABI (coeficiente = 9,00; 95%CI: 0,43; 17,5) y una presión sistólica sanguínea más alta (coeficiente = -0,13; 95%CI -0,24; -0,03) fueron predictores independientes para la disminución de la eGFR. El programa de ejercicio de dieciséis semanas no tuvo un efecto a largo plazo en la supervivencia, calidad de vida o cambio en la filtración glomerular en pacientes con etapas 2 a 4 enfermedad crónica de riñón. Una eGFR y ABI más bajos, y una presión más alta sistólica de sangre estuvieron asociadas con una prognosis más escasa entre pacientes enfermedad crónica de riñón.

OBJECTIVE: To evaluate the prevalence of reports of symptoms of COVID-19 among individuals with and without antibodies and identify those with greater capability to predict the presence of antibodies against SARS-CoV-2. METHODS: The study uses data collected in phases 5 to 8 of Epicovid-19-RS. The presence of antibodies against SARS-CoV-2 was evaluated by a rapid test. The occurrence of cough, fever, palpitations, sore throat, difficulty breathing, changes in taste and smell, vomiting, diarrhea, body pain, shaking, and headache since March 2020 was also evaluated. Then, the capability to predict the evaluated symptoms concerning the presence of antibodies was calculated. RESULTS: A total of 18,000 individuals were interviewed and 181 had antibodies against COVID-19 in phases 5 to 8. The proportion of asymptomatic individuals was 19.9% among participants with antibodies and 49.7% among those without antibodies. All symptoms were reported more frequently by individuals with antibodies. The division of the prevalence of symptoms among individuals with antibodies by the prevalence among individuals without antibodies showed the following prevalence ratios: for changes in smell or taste (9.1), fever (4.2), tremors (3.9), breathing difficulty (3.2) and cough (2.8 times). Anosmia and fever were the symptoms with a greater capability to predict the presence of antibodies. CONCLUSION: The prevalence of symptoms was higher among individuals with antibodies against SARS-CoV-2. The proportion of asymptomatic individuals was low. Altered smell or taste and fever were the symptoms that most predict the presence of antibodies. These results can help to identify probable cases, contributing to the clinical diagnosis and screening of patients for testing and isolation guidance in positive cases, especially in scenarios of the scarcity of diagnostic COVID-19 tests.
