RESUMEN
INTRODUCTION: Physical activity (PA) improves health outcomes for people with type II diabetes mellitus (diabetes), but little is known about PA among Dominicans. The purpose was to evaluate PA participation and perceptions among people with diabetes in the Dominican Republic (DR). METHODS: Participants (N=29) were recruited from an urban diabetes clinic in DR. PA was assessed via accelerometry and Godin Leisure Time Exercise Questionnaire (GLTEQ). RESULTS: Eighteen women and 11 men enrolled (age: 55 ± 13 years; BMI: 28.6 ± 4.5 kg·m-2). Twenty-seven participants reached acceptable wear time. Using a one-minute bout minimum, moderate- to vigorous-intensity PA (MVPA) was 152.2 ± 59.7 min·day-1; no vigorous PA was recorded. GLTEQ scores (103 ± 98) classified 25 participants as active. Around 93% reported that PA was "very important" for their health. There was no association between GLTEQ and MVPA (p>0.2). Participants who reported being "very active" (n=17) did more MVPA than those who were "rarely active" or "somewhat active" (n=10; p=0.02). CONCLUSION: Dominicans with diabetes are highly physically active but do very little vigorous PA. The GLTEQ was not an accurate measure of PA. Future research should develop validated questionnaires and evaluate structured exercise and dietary interventions.
RESUMEN
Over the past few years, organizations around the world have tried to reach different populations with recommendations about physical activity (PA), due to this subject playing an important role in the phases of intention development and in preparation for it. Thus, the knowledge of future educators in the fields of health and PA is of vital importance when improving the levels of the latter in students. The objective of this research is to determine what knowledge future teachers have about health and PA, examining possible disparities according to the gender, age, and level of physical exercise of the participants. In addition, the psychometric properties of the instrument used were explored. A total of 321 Colombian university students from the Faculty of Education between the ages of sixteen and thirty-five participated in this study, providing sociodemographic information by filling out the CUAFYS-A questionnaire. Significant differences were found in the scale items according to sex and self-perception of being physically active. Also, the findings revealed a single-factor structure with nine items that had satisfactory reliability (α = 0.71; CR = 0.72) and excellent goodness-of-fit indices (RMSEA = 0.055 (90% CI (0.3, 0.8), RMSR = 0.02, CFI = 0.935, NNFI = 0.912, CMIN/DF = 1.97). Therefore, strategies and campaigns to promote PA knowledge in prospective teachers should be tailored according to gender and PA levels. Similarly, the CUAFYS-A questionnaire can be considered a valid and reliable instrument to identify the PA knowledge of future educators.
RESUMEN
BACKGROUND: Social distancing measures designed to contain the COVID-19 pandemic can restrict physical activity, a particular concern for high-risk patient groups. We assessed rheumatoid arthritis patients' physical activity and sedentary behavior level, pain, fatigue, and health-related quality of life prior to and during the social distancing measures implemented in Sao Paulo, Brazil. METHODS: Post-menopausal females diagnosed with rheumatoid arthritis were assessed before (from March 2018 to March 2020) and during (from 24 May to 7 July 2020) social distancing measures to contain COVID-19 pandemic, using a within-subjects, repeated-measure design. Physical activity and sedentary behavior were assessed using accelerometry (ActivPAL micro). Pain, fatigue, and health-related quality of life were assessed by questionnaires. RESULTS: Mean age was 60.9 years and BMI was 29.5 Kg/m2. Disease activity ranged from remission to moderate activity. During social distancing, there were reductions in light-intensity activity (13.0% [-0.2 h/day, 95% CI: -0.4 to -0.04; p = 0.016]) and moderate-to-vigorous physical activity (38.8% [-4.5 min/day, 95% CI: -8.1 to -0.9; p = 0.015]), but not in standing time and sedentary time. However, time spent in prolonged bouts of sitting ≥30 min increased by 34% (1.0 h/day, 95% CI: 0.3 to 1.7; p = 0.006) and ≥60 min increased by 85% (1.0 h/day, 95% CI: 0.5 to 1.6). There were no changes in pain, fatigue, and health-related quality of life (all p > 0.050). CONCLUSIONS: Imposed social distancing measures to contain the COVID-19 outbreak were associated with decreased physical activity and increased prolonged sedentary behavior, but did not change clinical symptoms sitting among patients with rheumatoid arthritis.

OBJECTIVE: The novel coronavirus (SARS-CoV-2) has had an influence on almost the entire world and has become a major public health problem. Many countries have introduced measures that restrict the movement of the population and that may negatively influence the physical activity (PA) levels. The aim of this study was to examine the factors associated with changes in PA in Serbia during the COVID-19 outbreak. METHODS: The cross-sectional study was conducted from the 9th through the 13th of April 2020. A total of 340 people, all contacted using Viber, were invited to participate in the study. The study instrument was a questionnaire that gathered information regarding social characteristics, PA during the outbreak, PA before the outbreak, and fear of COVID-19. RESULTS: A total of 50 participants (14.7%) had low levels of PA in the 7 days prior to the study, while 133 (39.1%) had moderate and 106 (31.2%) had high levels of PA. The participants with high levels of PA had significantly higher energy expenditures before than after the COVID-19 outbreak (P < .001). There were no significant differences between the participants with different levels of PA in the scores on the Fear of COVID-19 scale (low: 13.4 ± 5.2; moderate: 12.6 ± 4.4; high: 13.8 ± 5.5; P = .204). CONCLUSION: One-sixth of the participants had low PA levels, and as restrictive measures are still in place in many countries, the lack of PA in high proportions of the general population may cause significant public health concerns.

BACKGROUND: Hemodialysis (HD) treatment affects functioning, physical activity level, clinical biomarkers, and body composition. However, the association between these variables with functioning, considering International Classification of Functioning, Disability and Health (ICF) domains remains unclear. Thus, the aim of this study was to investigate the possible association between physical activity, biomarkers, and body composition with functioning in HD patients in reference to the ICF. METHODS: Eighty HD patients performed different tests grouped according to ICF domain: Body structure and function - handgrip strength (HS), 5-repetition sit-to-stand test, and 60-s sit-to-stand test (5-STS, 60-STS, respectively); Activity - short physical performance battery (SPPB); and Participation - participation scale questionnaire. Physical activity [Human Activity Profile questionnaire (HAP)], body composition (Dual-energy X-ray absorptiometry), Parathormone (PTH), and alkaline phosphatase were analyzed as possible variables associated with ICF domains. Data analyses were performed using simple and multiple regression models adjusted for age, duration of HD, and diuresis volume. RESULTS: In the body structure and function domain, appendicular lean mass, PTH level, and age were associated with HS (R2 = 0.558); HAP and PTH were associated with 5-STS (R2 = 0.263); and HAP, PTH, duration of HD, and age were associated with 60-STS (R2 = 0.337). In the activity domain, HAP, PTH, alkaline phosphatase, duration of HD, age, and body fat were associated with SPPB (R2 = 0.689). Finally, only HAP was associated with the participation scale (R2 = 0.067). CONCLUSION: Physical activity and PTH levels are determinant protagonists of functioning in all ICF domains in hemodialysis patients.

BACKGROUND: The 6-min walk test (6MWT) is a simple, inexpensive, reliable, and reproducible test that provides a reasonable estimate of the cardiorespiratory fitness (CRF). We aimed to assess the reliability and reproducibility of a self-administered 6MWT in asymptomatic adults using a free smartphone app. METHODS: In the 1st phase, 93 participants underwent a supervised 6MWT (6MWTsup) in a 30 m indoor corridor, using a triaxial accelerometer and their smartphones to compare the total step counts and to develop a 6-min walk distance (6MWD) prediction equation. In the 2nd phase, 25 participants performed the 6MWTsup and two self-administered 6MWTs outdoors (6MWTsa1 and 6MWTsa2, at least 48 h apart) using a free smartphone app. RESULTS: The agreement between accelerometer- and app-based total step counts was limited (mean difference, -58.7 steps (-8.7%): 95% confidence interval, -326.5 (-46.8%) to 209.1 (29.3%)). The best algorithm for predicting the 6MWTsupm included: 795.456 + (0.815 heightm app-steps) - (1.620 ageyears) - (3.005 weightkg) - (1.155 app-steps), R2 = 0.609). The intraclass correlation coefficient between 6MWTsa2 and 6MWTsa1 was excellent (0.91: 0.81-0.96). The coefficient of variation was 6.4%. The agreement between the two self-administered tests was narrow (-1.9 (0.2%) meters: -57.4 (-9.5%) to 61.3 (9.9%)). CONCLUSIONS: The self-administered 6MWT has excellent reliability and reproducibility in asymptomatic adults, being a valuable tool for assessing CRF in community-based interventions.

Os participantes foram submetidos à espirometria, bioimpedância, avaliação da capacidade de exercício com teste de Shuttle modificado (MST), o nível da atividade física foi medido por meio do questionário internacional de atividade física (IPAQ) e usando acelerômetro por 5 dias. Participaram 30 indivíduos com idade de 11,2 ± 3,6 anos e volume expirado forçado (VEF1) de 68,0 ± 24,8%. A mediana da distância percorrida no MST foi de 820 metros (66,3%) e demonstrou associação com a função pulmonar (r = 0,78), estado nutricional (r = 0,38), tempo de hospitalização (r = -0,42) e uso de antibióticos (r = -0,46). De acordo com o questionário, 20 pacientes (64,6%) foram classificados como sedentários, o acelerômetro revelou que os indivíduos passam 354,2 minutos em atividades sedentárias e apenas 14,9 minutos em atividades moderadas a vigorosas por dia. Quanto maior a porcentagem de tempo em atividade física moderada a vigorosa, maior o índice de massa corpórea (IMC) e menor o tempo de hospitalização. Assim, a capacidade de exercício e nível de atividade física em crianças e adolescentes com fibrose cística apresentou-se reduzida e associada com menores valores de IMC e aumento do tempo de hospitalização.
RESUMEN El propósito de este trabajo fue evaluar la capacidad de ejercicio y el nivel de actividad física diaria de los niños y adolescentes con fibrosis quística, así como asociarlos con el estado nutricional, la función pulmonar, la duración de la permanencia hospitalaria y el uso de antibióticos. Este es un estudio transversal realizado con individuos con fibrosis quística con edades comprendidas entre los 6 y los 18 años, y que registra información sobre el perfil clínico, los antecedentes de hospitalizaciones y el uso de antibióticos. Los participantes se sometieron a la espirometría, la bioimpedancia, la evaluación de la capacidad de ejercicio con la prueba de Shuttle modificada (MST); para medir el nivel de actividad física se aplicó el Cuestionario Internacional de Actividad Física (IPAQ) y el uso del acelerómetro durante 5 días. Participaron 30 personas de entre 11,2 ± 3,6 años de edad y volumen espirado forzado (VEF1) de 68,0 ± 24,8%. La mediana de la distancia recorrida en el MST fue de 820 metros (66,3%) y se mostró asociación con la función pulmonar (r=0,78), el estado nutricional (r=0,38), la duración de la permanencia hospitalaria (r=-0,42) y el uso de antibióticos (r=-0,46). El cuestionario reveló que 20 pacientes (64,6%) estaban sedentarios, y el acelerómetro evidenció que ellos pasan 354,2 minutos en actividades sedentarias y solo 14,9 minutos en actividades moderadas a intensas al día. Cuanto mayor sea el porcentaje de tiempo dedicado a la actividad física moderada a intensa, mayor será el índice de masa corporal (IMC) y menor la duración de la permanencia hospitalaria. Por lo tanto, la capacidad de ejercicio y el nivel de actividad física de niños y adolescentes con fibrosis quística fueron menores y están asociadas con bajos valores de IMC y con una permanencia hospitalaria más prolongada.
ABSTRACT To evaluate the exercise capacity and daily physical activity level among children and adolescents with cystic fibrosis, and its association with nutritional status, lung function, hospitalization time, and days taking antibiotics. This is a cross-sectional study in individuals with cystic fibrosis aged 6 to 18 years. Information on clinical profile, history of hospitalizations and antibiotic use were collected. Participants were submitted to spirometry, bioimpedance, and an assessment of exercise capacity with modified shuttle test (MST), and the level of physical activity was measured with the International Physical Activity Questionnaire (IPAQ) using an accelerometer for 5 days. In total, 30 individuals participated, aged 11.2±3.6 years, and 68.0±24.8% in forced expired volume in the first second (FEV1). The median distance covered in the MST was 820 meters (66.3%), showing association with lung function (r=0.78), nutritional status (r=0.38), hospitalization time (r=-0.42) and antibiotic use (r=-0.46). According to the questionnaire, 20 patients (64.6%) were classified as sedentary, the accelerometer revealed that the individuals spend 354.2 minutes in sedentary activities and only 14.9 minutes in moderate to vigorous activities per day. The higher the percentage of time in moderate to vigorous physical activity, the higher the body mass index (BMI) and the shorter the hospitalization time. Exercise capacity and level of physical activity in children and adolescents with cystic fibrosis is reduced and associated with lower BMI values and with an increase in hospitalization time.
RESUMEN
This study aimed atassessingthe physical activitylevel, heart rate and the salivary cortisol level of football society players.The sample consisted of 19 male mastersfootballplayerswith an average age of 56.7±3.9 years. The long form of the International Physical Activity Questionnaire (IPAQ)andPolar®heart rate monitors were usedas instruments, in additionto Salivette® tubes to measure salivary cortisol. Data analysis was performed by using the repeated measuresAnalysis of Variance (ANOVA) with Bonferroni post hoctest,and Spearman's Rank Correlation Coefficient. The results showed that the salivary cortisol concentration indicated an index of 1.97 ng/ml at the beginning of the match;40 minutes after that thesevalues increased to 8.00 ng/ml,and 60 minutesafter the match had started they reached 8.40 ng/ml. Considering the post-match moment, a moderate and positive correlation between the salivary cortisol concentration and heart rate (averageand maximum) wasseen. In conclusion,the physical effort expended during football Society practice needs to be monitored due to the high heart rate and high increase in the salivary cortisol concentrationofthis age group.

Low-income women are the group with the highest levels of obesity worldwide. In low-income settings, the use of predictive equations, which yield a measure of the individuals' BMR, is a feasible approach to estimate the individuals' total energy expenditure (TEE), using the factorial method (calculated-TEE = BMR × physical activity level), an important step of the obesity nutritional care. The present study aimed to identify the predictive equation that, in conjunction with metabolic equivalents of tasks (MET) data from accelerometers, yields the calculated-TEE with better agreement compared with the TEE measured by doubly labelled water (TEE-DLW). Forty-five women aged 19-45 years, with excess weight and mothers of undernourished children, were included. They received DLW to determine TEE (14 d); at the same time, they used triaxial accelerometers (7 d) to estimate their MET. The Bland-Altman method, paired-sample t tests, concordance correlation coefficient and root-mean-square error were used to assess the agreement. Maximum allowed differences were defined as 24 %, based on the within-variance coefficient of the energy intake of the sample. Eleven equations were studied. The calculated-TEE obtained by five equations showed non-significant bias: Dietary Reference Intake (Institute of Medicine (2005) Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids), FAO/WHO/UNU ((2001) Food and Nutrition Technical Report Series), Harris & Benedict ((1919) Proc Natl Acad Sci USA4, 370-373), Henry & Rees ((1991) Eur J Clin Nutr45, 177-185) and Schofield ((1985) Hum Nutr Clin Nutr39, 5-41). The mean percentage differences were -1·5, -0·8, 2·2, -2·2 and 2·0 %, respectively. Considering all parameters, FAO/WHO/UNU ((2001) Food and Nutrition Technical Report Series) equation performed slightly better than the others; nevertheless, no equation in conjunction with the estimated-MET showed a calculated-TEE with its CI for the Bland-Altman limits of agreement inside the pre-defined acceptable range.

BACKGROUND: Patients with major depression disorder presents increased rates of cognitive decline, reduced hippocampal volume, poor sleep quality, hypertension, obesity, suicidal ideation and behavior, and decreased functionality. Although continuous aerobic exercise (CAE) improves some of the aforementioned symptoms, comorbidities, and conditions, recent studies have suggested that performing aerobic exercise with motor complexity (AEMC) may be more beneficial for cognitive decline, hippocampal volume, and functionality. Therefore, this randomized controlled trial will compare the effects of CAE and AEMC on depression score, cognitive function, hippocampal volume, brain-derived neurotrophic factor expression, sleep parameters, cardiovascular risk parameters, suicidal behavior, functionality, and treatment costs in patients with depression. METHODS/DESIGN: Seventy-five medicated patients with depression will be recruited from a Basic Healthcare Unit to participate in this prospective, parallel group, single blinded, superiority, randomized controlled trial. Patients with depression according to DSM-V criteria will be balanced and randomly assigned (based on depression scores and number of depressive episodes) to a non-exercising control (C), CAE, and AEMC groups. The CAE and AEMC groups will exercise for 60 min, twice a week for 24 weeks (on non-consecutive days). Exercise intensity will be maintained between 12 and 14 points of the rating of perceived exertion scale (~ 70-80% of the maximum heart rate). The CAE group will perform a continuous aerobic exercise while the AEMC group will perform exercises with progressively increased motor complexity. Blinded raters will assess patients before and after the intervention period. The primary outcome measure will be the change in depression score measured by the Montgomery-Asberg Depression Rating Scale. Secondary outcomes will include measures of cognitive function, hippocampal volume, brain-derived neurotrophic factor expression, sleep parameters, cardiovascular risk parameters, suicidal behavior, functionality, and treatment costs. DISCUSSION: This study was selected in the call of public policy programs for the Brazilian Unified National Health System - "PPSUS 2015". To our knowledge, this is the first pragmatic trial to test the effect of adding AEMC to the pharmacological treatment of patients with depression and to evaluate the possible reductions in depression symptoms and healthcare costs. TRIAL REGISTRATION: Brazilian Clinical Trials Registry (ReBec) - RBR-9zgxzd - Registered on 4 Jan. 2017.

BACKGROUND: Physical activity level (PAL) is known to play an important role in reducing risk factors associated with sedentarism, in addition to improving the mental health and health-related quality of life (HRQL). OBJECTIVE: Investigate the relationship of PAL and their domains with HRQL, mood state (MS) and anxiety. Method: 140 Physical Education students (23.6 ± 3.7 years) were evaluated. The Baecke Habitual Physical Activity and Quality of Life (QOL-36) questionnaires, State-Trait Anxiety Inventories (STAI-S and STAI-T) and Profile of Mood States (POMS) scale were used to investigate PAL, HRQL and mental health indicators. Pearson's correlation coefficient examined the association between PAL and both mental health and HRQL parameters. RESULTS: There was a correlation between state anxiety and both the domain leisure-time physical activity (LTPA) (p = 0.013) and total PAL score (p = 0.010). In relation to MS, a negative correlation was found between LTPA and total mood disorder (TMD) (p = 0.004). However, there were positive correlations between the vigor subscale and both LTPA (p=0.001) and total PAL (p=0.019). With respect to HRQL, analysis of the relationship between LTPA and total PAL demonstrated positive coefficients with the physical component summary (PCS) (p=0.000; p = 0.005), mental component summary (MCS) (p = 0.000; p = 0.006) and total HRQL (p = 0.000; p = 0.003). CONCLUSION: The findings suggest that the rise in LTPA was related to an increase in HRQL and MS. However, PAL was positively related to anxiety.
RESUMEN
BACKGROUND: Physical activity levels seem to play a role in patellofemoral pain (PFP); however, few studies have been conducted to confirm this hypothesis. OBJECTIVES: To determine the reported pain levels of women with and without PFP who maintain different levels of physical activity; to determine the capability of these levels to predict pain; and to test the capability of two stair-negotiation protocols, with and without external load, to equalize pain between groups. METHOD: Four groups were divided based on the women's physical activity levels: moderate activity PFP group (28), moderate activity control group (23), intense activity PFP group (22), and intense activity control group (22). All participants were asked to perform 15 repetitions of stair negotiation with and without external load on a seven-step staircase on two separate days. Pain levels were reported using a visual analog scale at five distinct moments: previous month, before stair negotiation, after stair negotiation, before patellofemoral joint (PFJ) loading protocol, and after PFJ loading protocol. RESULTS: The intense activity PFP group showed higher levels of pain than the moderate activity PFP group (F(8,158)=11.714, p=0.000, η2=0.30). The PFJ loading protocol was able to equalize and exacerbate pain in the PFP groups. CONCLUSION: Intense physical activity seems to have a higher association with knee pain than moderate physical activity. A PFJ loading protocol may be an alternative to equalize pain in women with PFP during clinical assessments.

Research using questionnaires has shown that physical activity level (PAL) is associated with healthcare costs. The purpose of this study was to examine the association between objectively measured PAL and healthcare costs among hypertensive and diabetic noninstitutionalized Brazilian older people. The method consisted of a cross-sectional study forming part of the SABE Study, composed of 377 older people interviewed in 2010. Expenditures were estimated taking into account self-reported medicine prescription, outpatient service, and hospitalizations, with the highest quartile of expenditures considered as a risk category. PAL was estimated using an Actigraph accelerometer. Associations were expressed as odds ratios and 95% confidence intervals, adjusted for covariates. Overall expenditures were higher in the sedentary group. The insufficiently active group presented greater odds for higher total, outpatient, and hospitalization expenditure. It was concluded that healthcare expenditures were lower in more active hypertensive and diabetic older people. The promotion of physical activity could be relevant in the attenuation of the burden of chronic diseases in economic losses.

This cross-sectional study analyzed the association between physical activity (PA) and social jetlag (SJL) among shift workers. We evaluated 423 employees, aged between 18 and 60 years, who worked in a poultry-processing company in Brazil. Physical activity levels (PAL) were determined by the short form of the International Physical Activity Questionnaire (IPAQ-SF). SJL was calculated as the absolute difference between the time of mid-sleep on work and free days. The percentage of workers insufficiently active was high on all shifts, with no significant differences between the 3 shifts. The amount of time spent in sedentary behavior on workdays did not differ between shifts. Among night-shift workers, negative associations were observed between SJL and 1) the duration and weekly energy expenditure while walking; 2) the frequency of moderate and vigorous PA; and 3) the total energy expenditure related to PA. Even though PAL did not differ among workers on different shifts, we found a high prevalence of subjects who were insufficiently active or too sedentary among all groups. Also, SJL was negatively associated with PA in night-shift workers. These results suggest that PA should be encouraged among shift workers and that SJL may be an important factor in reducing PA in this cohort.

OBJECTIVE: To compare muscle strength (i.e. lower- and upper-body strength) and function between physically inactive childhood-onset systemic lupus erythematosus patients (C-SLE) and healthy controls (CTRL). METHODS: This was a cross-sectional study and the sample consisted of 19 C-SLE (age between 9 and 18 years) and 15 CTRL matched by age, sex, body mass index (BMI), and physical activity levels (assessed by accelerometry). Lower- and upper-body strength was assessed by the one-repetition-maximum (1-RM) test. Isometric strength was assessed through a handgrip dynamometer. Muscle function was evaluated by the timed-stands test (TST) and the timed-up-and-go test (TUG). RESULTS: When compared with CTRL, C-SLE showed lower leg-press and bench-press 1-RM (p=0.026 and p=0.008, respectively), and a tendency toward lower handgrip strength (p=0.052). C-SLE showed lower TST scores (p=0.036) and a tendency toward higher TUG scores (p=0.070) when compared with CTRL. CONCLUSION: Physically inactive C-SLE patients with very mild disease showed reduced muscle strength and functionality when compared with healthy controls matched by physical activity levels. These findings suggest C-SLE patients may greatly suffer from a physically inactive lifestyle than healthy controls do. Moreover, some sub-clinical "residual" effect of the disease or its pharmacological treatment seems to affect C-SLE patients even with a well-controlled disease.

RESUMO Objetivo: Comparar a força muscular (ou seja, a força muscular dos membros superiores e inferiores) e a capacidade funcional de pacientes fisicamente inativos com lúpus eritematoso sistêmico de início juvenil (LESJ) com controles saudáveis (CTRL). Métodos: Estudo transversal cuja amostra foi composta por 19 pacientes com LESJ (entre 9 e 18 anos) e 15 CTRL pareados por idade, sexo, índice de massa corporal (IMC) e nível de atividade física (avaliada através do uso de acelerômetros). A força dos membros superiores e inferiores foi avaliada pelo teste de uma repetição máxima (1-RM). A força isométrica foi avaliada através do uso de um dinamômetro. A capacidade funcional foi avaliada pelo Timed-stands test (TST) e Timed-up-and-go test (TUG). Resultados: Quando comparados com os CTRL, os pacientes com LESJ apresentaram menor força em 1-RM no Leg press e supino (p = 0,026 e p = 0,008, respectivamente) e uma tendência a menor força de preensão manual (p = 0,052). Os pacientes com LESJ apresentaram menores escores no TST (p = 0,036) e uma tendência a maior pontuação no TUG (p = 0,070), quando comparados com o grupo CTRL. Conclusão Pacientes com LESJ, fisicamente inativos, com doença muito leve mostraram redução na força muscular e capacidade funcional quando comparados com controles saudáveis pareados por níveis de atividade física. Esses achados sugerem que pacientes com LESJ podem apresentar mais efeitos deletérios por manter um estilo de vida fisicamente inativo do que controles saudáveis. Além disso, alguns efeitos “residuais” subclínicos da doença ou do tratamento farmacológico parecem afetar pacientes com LESJ, mesmo com uma doença bem controlada.

To examine the agreement and association between objectively measured and indirectly assessed physical activity levels in patients with juvenile dermatomyositis (JDM) and juvenile systemic lupus erythematosus (JSLE) patients. The sample consisted of 19 JDM patients (age 8 to 22 years) and 20 JSLE patients (age 9 to 18 years). Physical activity level was objectively measured using Actigraph® accelerometers and indirectly assessed by the short-form International Physical Activity Questionnaire (IPAQ). Spearman's correlation coefficients were calculated to test possible associations between physical activity levels across the two instruments. The Bland-Altman technique was used to calculate bias and limits of agreement. Correlations between objectively measured and indirectly assessed physical activity levels in JDM and JSLE were weak, varying from R = 0.03 to R = 0.33 (all p > 0.05). Total physical activity was correlated between accelerometer and IPAQ in JSLE (R = 0.51, p = 0.021). Bland-Altman analyses suggested that IPAQ tended to highly underestimate sedentary time and light physical activity in JDM (mean bias 105.7 and 199.8 min, respectively) and JSLE (mean bias 36.4 and 127.8 min, respectively). Mean biases of moderate-to-vigorous physical activity were also highly variable, ranging from -42.9 to 54.9 min and -59.4 to 89.8 min for JDM and JSLE, respectively. IPAQ was shown to not be valid to assess physical activity levels in patients with JDM and JSLE when compared against accelerometry. While the validation of reliable self-reported instruments that measure physical activity in pediatric rheumatic patients remains necessary, the use of validated tools that objectively measure physical activity is recommended in both clinical and research settings.
