RESUMEN

OBJECTIVES: The purpose of this investigation was to verify the association between mental health (MH) indicators with walking capacity in patients with PAD. METHODS: Two hundred and forty-six patients with PAD and claudication symptoms participated in this study. Physical function was assessed objectively with the 6-min walk test (6MWT) and subjectively using the Walking Impairment Questionnaire (WIQ). MH was assessed by the World Health Organization Quality of Life-Bref (WHOQOL-Bref) (six questions were selected - 1, 2, 10, 16, 19, and 26). Patients were divided into tertile groups according to their composite z-score for mental health (Low MH, Middle MH, and High MH). RESULTS: The High MH group presented higher scores (p < 0.05) for the WIQ (distance = 26.8 ± 25.6, speed = 25.4 ± 17.3, and stairs = 33.6 ± 27.5), claudication onset distance (161.6 ± 83.6 m), and total walking distance (352.9 ± 79.6 m) compared to Low MH (WIQ distance = 14.8 ± 16.2, 17.7 ± 13.0, and stairs = 22.7 ± 20.7). Additionally, the High MH group presented a longer claudication onset distance (115.5 ± 70.5 m), and total walking distance in 6MWT (306.6 ± 83.2 m), and higher scores in the total walking distance compared to Middle MH (309.5 ± 93.6 m) (p < 0.05). CONCLUSION: In patients with PAD, MH was positively associated with walking capacity. Based on these results, treatments that can improve mental health, through different mechanisms, can also positively influence the ability of these patients to walk.

RESUMEN

The aims of the current study were to analyze the association between the barriers to and changes in physical activity levels and sedentary behavior, as well as to examine whether these barriers change over time in patients with peripheral artery disease. In this longitudinal study, we assessed 72 patients (68% men; 65.7 ± 9.2 years). Physical activity was measured over a 7-day period using an accelerometer, and data were collected on time spent in sedentary activities, low-light physical activities, and moderate-to-vigorous physical activities. Personal and environmental barriers to physical activity were collected using yes or no questions. Assessments were repeated in the same patients after 27 months (95% confidence interval [26, 28] months). Most barriers remained stable in these patients; however, those who reported lack of money experienced an increase in sedentary behavior (ß = 392.9 [159.7] min/week, p = .02) and a decrease in low-light physical activity (ß = -372.4 [140.1] min/week, p = .02). These findings suggest that patients with symptomatic peripheral artery disease typically exhibit stable barriers over time, and individuals reporting lack of money demonstrated a decrease in low-light physical activity and an increase in sedentary behavior after 27 months.

RESUMEN

BACKGROUND: The mechanisms underlying functional impairments in symptomatic PAD patients are controversial and poorly understood. Endothelial dysfunction and arterial stiffness have been proposed as potential mechanisms related to functional impairment in symptomatic PAD patients, however, more studies are needed to confirm these associations. OBJECTIVE: To analyze the association between vascular function and walking impairment in patients with peripheral arterial disease (PAD) and symptoms of claudication. METHODS: This was a cross-sectional study that included 68 patients with symptomatic PAD. All patients underwent an objective (Six-minute walk test [6MWT], 4-meter walk test) and a subjective (Walking Impairment Questionnaire [WIQ]) measurement of walking impairment. Vascular parameters measured were pulse-wave velocity (PWV) and flow-mediated dilation (FMD). Multiple linear regression was performed to investigate the association among walking impairment variables with vascular function parameters. RESULTS: No significant associations between the claudication onset distance (PWV: b=.060, P = 0.842; FMD: b=-.192, P = 0.456), 6MWT (PWV: b=.007, P = 0..975; FMD: b=.090, P = 0.725), WIQ distance (PWV: b=.337, P = 0.117; FMD: b=-.025, P = 0.895) WIQ speed (PWV: b=.320, P = 0.181; FMD: b=-.028, P = 0.497), WIQ stairs (PWV: b=.256, P = 0.204; FMD: b=-.228, P = 0.230), 4-meter usual walk (PWV: b=-.421, P = 0.107; FMD: b=-.338, P = 0.112), 4-meter fast walk (PWV: b=-.496, P = 0.063; FMD: b=-.371, P = 0.086) and vascular function were found. CONCLUSIONS: In symptomatic PAD patients, vascular function is not associated to walking impairment, even when adjusting for comorbid conditions and diabetes.

RESUMEN

BACKGROUND: Exercise program has been recommended for the treatment of symptomatic peripheral artery disease (PAD) patients. However, whether exercise promotes reduction in arterial stiffness in these patients, who exhibit high arterial stiffness, is poor known. AIM: To analyze the effects of a single session of resistance, walking, and combined exercises on arterial stiffness in symptomatic PAD patients and to describe individual responses and identify clinical predictors of arterial stiffness responses after exercises. METHODS: Twelve patients with symptomatic PAD underwent four experimental sessions in random order: walking exercise (W - 10 bouts of 2-min walking at the speed corresponding to the onset of claudication pain with 2-min interval among sets), resistance exercise (R - 2 sets of 10 reps in eight resistance exercises), combined exercise (CO - 1 set of 10 reps in eight resistance exercises + 5 bouts of 2-min walking with 2-min interval between) and control session (C - resting in exercise room). Ambulatory arterial stiffness index (AASI) was obtained during ambulatory period after each session. Body mass index, ankle brachial index, sex and age also were evaluated. RESULTS: AASI was lower in R compared to other sessions (R - 0.52 ± 0.05; W - 0.59 ± 0.05; CO - 0.64 ± 0.05; C - 0.60 ± 0.05, P < 0.001), with 75% of patients presenting lower AASI after R session. No difference was found between W, CO and C sessions (P> 0.05). Ankle brachial index was negatively correlated with R and W sessions net effect (r = -0.618 and -0.750, respectively; P< 0.05 for both), no correlation was found with CO. CONCLUSION: A single bout of resistance exercise acutely reduces arterial stiffness in symptomatic PAD, while walking and combined exercise did not alter this variable. This response is more likely to occur in individuals with less severe disease.

RESUMEN

BACKGROUND: The Coronavirus 2019 (COVID-19) pandemic has had a negative impact on the population's behavior. In this context, the effect of the COVID-19 pandemic on drug treatment of patients with peripheral arterial disease (PAD) and intermittent claudication (IC) remains unclear. OBJECTIVES: To analyze the impact of the COVID-19 pandemic on drug treatment of patients with PAD and IC. METHODS: In this cross-sectional, observational study, 136 patients with PAD and IC were recruited from our database and answered a questionnaire by telephone involving the following questions: a) precautions related to COVID-19; b) general health status; and c) treatment of diseases. Subsequently, patients were divided into two groups according to difficulty in obtaining their drugs (DOD: difficulty obtaining drugs, or NDOD: no difficulty obtaining drugs) and overall health was compared between groups. RESULTS: Seventeen percent of patients reported difficulties with obtaining drugs during the pandemic. A higher proportion of these patients reported being sadder (56.5% vs. 24.8%, P < 0.01) and having more difficulty sleeping (56.5% vs. 24.8%, P < 0.01) than of the patients in the NDOD group (P <0.01). The groups did not differ in terms of impairment of walking capability, anxiety, stress, or depression (P> 0.05). CONCLUSIONS: A higher proportion of patients in the DOD group reported being sadder and having greater difficulty sleeping compared to the NDOD group during the COVID-19 pandemic.

RESUMEN

PURPOSE: The aim of this study was to analyze the effects of isometric handgrip training (IHT) on ambulatory blood pressure (BP) in individuals aged 18 yr and older. REVIEW METHODS: A systematic review and meta-analysis was performed in Medline and Web of Science, encompassing studies published until July 2023, as well as the gray literature. We calculated the mean difference (MD) and 95% CI using an inverse variance method with a random effects model. SUMMARY: Considering both published and unpublished studies, we observed an effect of IHT on awake diastolic BP (MD = -2.02; 95% CI, -3.89 to -0.15 mmHg; P = .03). There were no significant effects on 24-hr systolic BP (MD = -1.31; 95% CI, -3.84 to 1.22 mmHg; P = .31), asleep systolic BP (MD = -0.84; 95% CI, -3.31 to 1.63 mmHg; P = .50), awake systolic BP (MD = -0.93: 95% CI, -3.10 to 1.23 mmHg; P = .40), 24-hr diastolic BP (MD = -0.96; 95% CI, -2.65 to 0.74 mmHg; P = .27), or asleep diastolic BP (MD = -1.27; 95% CI, -3.22 to 0.67 mmHg; P = .20). In conclusion, the effects of IHT on ambulatory BP were observed primarily in awake diastolic BP among individuals over 18 yr of age.

RESUMEN

PURPOSE: The six-minute walk test (6MWT) is extensively employed to evaluate gait impairment in patients with symptomatic peripheral artery disease (PAD) and has been associated with different health outcomes. However, various approaches exist for calculating and interpreting the six-minute test in order to address the needs of patients more effectively. Therefore, we investigated how these different approaches correlate with functional capacity and cardiovascular health in patients with symptomatic PAD. METHODS: In total, 227 PAD patients [65.2% men and 67 (13) y.o.] were included in this cross-sectional study. The 6MWT was performed along a 30-meter corridor and the distance was expressed in three ways: absolute (described as the meters walked during the test), relativized (based on the results of the 6MWT in healthy individuals), and DW (multiplying the body weight in kilograms by the absolute distance in the 6MWT). A functional capacity z-score was calculated using the results of the handgrip strength test, 4-meter walking test, and sit-and-stand test. A cardiovascular parameter z-score was calculated with data on brachial and central blood pressure, the low-frequency component/high-frequency component ratio, and carotid-femoral pulse wave velocity. RESULTS: The absolute (b = 0.30, 95%CI: 18-0.43, R² = 0.11, p < 0.001) and DW (b = 0.40, 95%CI: 27-0.53, R² = 0.17, p < 0.001) measures were related to functional capacity, independently of sex, age, and the ankle-arm index of the patients. Neither absolute nor DW were related to cardiovascular health. The relativized measure was not associated with either functional capacity or cardiovascular health. CONCLUSION: In patients with symptomatic PAD, absolute and DW measures are related to functional capacity, but not cardiovascular function.

RESUMEN

BACKGROUND: Previous cross-sectional studies have demonstrated that physical activity is associated with lower cardiovascular risk in patients with peripheral artery disease (PAD). However, it is not possible to establish causality, and longitudinal design studies are required. OBJECTIVE: To analyze the changes in cardiovascular risk parameters and physical activity levels after a 2-year follow-up in patients with symptomatic PAD. METHODS: This study started in 2015. In the first phase, 268 patients were included. In the second phase, after 2 years (median = 26 months), 72 patients were re-evaluated. Cardiovascular risk parameters, such as blood pressure, cardiac autonomic modulation, and arterial stiffness, and physical activity levels were measured at baseline and after 2 years of follow-up. Association among delta changes (values from follow-up - baseline) in physical activity and cardiovascular parameters were analyzed by multiple linear regression. The significance level was set at p < 0.05. RESULTS: Patients reduced their total physical activity levels compared to baseline (baseline = 2257.6 ± 774.5 versus follow-up = 2041 ± 676.2 min/week, p = 0.001). After follow-up, ankle-brachial index (0.62 ± 0.20 versus 0.54 ± 0.20, p = 0.003), and standard deviation of all RR intervals (43.4 ± 27.0 versus 25.1 ± 13.4 ms, p < 0.001) were lower, whereas carotid-femoral pulse wave velocity was higher (9.0 ± 3.0 versus 10.7 ± 3.4 m/s, p = 0.002) compared to baseline values. We did not observe any association among delta values of physical activity levels and cardiovascular risk parameters. CONCLUSION: Patients with PAD had reduced physical activity levels and impaired cardiovascular risk parameters during 2-year follow-up.


FUNDAMENTO: Estudos transversais anteriores demonstraram que a atividade física está associada a menor risco cardiovascular em pacientes com doença arterial periférica (DAP). No entanto, não é possível estabelecer causalidade e estudos com desenho longitudinal são necessários. OBJETIVO: Analisar as alterações nos parâmetros de risco cardiovascular e níveis de atividade física após 2 anos de acompanhamento em pacientes com DAP sintomática. MÉTODOS: O presente estudo teve início em 2015. Na primeira fase, foram incluídos 268 pacientes. Na segunda fase, após 2 anos (mediana = 26 meses), foram reavaliados 72 pacientes. Parâmetros de risco cardiovascular, como pressão arterial, modulação autonômica cardíaca e rigidez arterial, e níveis de atividade física foram medidos na linha de base e após 2 anos de acompanhamento. A associação entre as alterações delta (valores após 2 anos ­ valores da linha de base) na atividade física e nos parâmetros cardiovasculares foi analisada por meio de regressão linear múltipla. O nível de significância foi estabelecido em p < 0,05 com DAP. RESULTADOS: Pacientes reduziram seus níveis totais de atividade física em comparação com a linha de base (linha de base = 2.257,6 ± 774,5 versus acompanhamento = 2.041 ± 676,2 min/semana, p = 0,001). Após o acompanhamento, o índice tornozelo-braquial (0,62 ± 0,20 versus 0,54 ± 0,20, p = 0,003) e o desvio padrão de todos os intervalos RR (43,4 ± 27,0 versus 25,1 ± 13,4 ms, p < 0,001) foram menores, enquanto a velocidade da onda de pulso carotídeo-femoral foi maior (9,0 ± 3,0 versus 10,7 ± 3,4 m/s, p = 0,002) em relação aos valores basais. Não observamos associação entre os valores delta dos níveis de atividade física e os parâmetros de risco cardiovascular. CONCLUSÃO: Pacientes com DAP tiveram níveis reduzidos de atividade física e comprometimento em relação aos parâmetros de risco cardiovascular após 2 anos de acompanhamento.

RESUMEN

OBJECTIVE: To verify the association of changes on physical activity levels during coronavirus disease 2019 (COVID-19) outbreak of individuals with normal weight and overweight/obesity, and the influence of sex in this relationship. METHODS: This cross-sectional study (survey research) was conducted in Brazil between May 5 and May 17, 2020. Participants (n=1,828 / 1,062 women >18 years) were invited through social media to answer a structured questionnaire via Google Forms. The online assessment included self-reported responses to questions on physical activity, overall health, weight, and height. Binary logistic regression analyzed the relationship between overweight/obesity (body mass index ≥25kg/m2), the impact of COVID-19 on physical activity level, and the influence of sex. RESULTS: Compared to normal weight people, those with overweight/obesity practice less moderate to vigorous physical activity (p<0.001). There were associations between women and men with overweight/obesity and the impact of COVID-19 on the physical activity practice compared to normal weight people, adjusted by age, education level, social isolation, and previous physical activity level (p<0.017). CONCLUSION: The study found an association of weight and changes in physical activity levels. Individuals with overweight/obesity were more likely to have a lower physical activity level during COVID-19 pandemic, regardless of sex.

RESUMEN

BACKGROUND: Exercise with self-selected intensity (SSI) has emerged as a new strategy for exercise prescription aiming to increase exercise adherence in Parkinson's disease (PD). OBJECTIVE: We compared the cardiovascular, perceived exertion and affective responses during traditional aerobic exercise and with SSI in PD. METHODS: Twenty patients with PD performed two aerobic exercise sessions in random order with an interval of at least 72 h between them: Traditional session (cycle ergometer, 25 min, 50 rpm) with imposed intensity (II) (60-80% maximum heart rate [HR]) and SSI: (cycle ergometer, 25 min, 50 rpm) with SSI. The HR (Polar V800 monitor), systolic blood pressure (auscultatory method), rating of perceived exertion (Borg scale 6-20) and affective responses (feeling scale) were assessed during the exercise at 8th and 18th minute. The Generalized Estimating Equation Model was used for comparison between both sessions (P < 0.05). RESULTS: The exercise intensity was not significantly different between both exercise sessions (8th minute: II -76.3±1.0 vs. SSI -76.5±1.3 % of maximal HR; 18th minute: II -78.9±0.9 vs. SSI -79.1±1.3 % of maximal HR, p = 0.93). Blood pressure, perceived exertion and affective responses were also not significantly different between both sessions (P > 0.05). CONCLUSIONS: Cardiovascular and psychophysiological responses were not different during aerobic exercise performed with II and with SSI in patients with PD.

RESUMEN

OBJECTIVE: To examine the impact of hypertension on cardiovascular health in patients with symptomatic peripheral artery disease and to identify factors associated with uncontrolled hypertension. METHODS: A cross-sectional study including 251 patients with symptomatic peripheral artery disease (63.9% males, mean age 67±10 years). Following hypertension diagnosis, blood pressure was measured to determine control of hypertension. Arterial stiffness (carotid-femoral pulse wave velocity) and cardiac autonomic modulation (sympathovagal balance) were assessed. RESULTS: Hypertension was associated with higher carotid-femoral pulse wave velocity, regardless of sex, age, ankle-brachial index, body mass index, walking capacity, heart rate, or comorbidities (ß=2.59±0.76m/s, b=0.318, p=0.003). Patients with systolic blood pressure ≥120mmHg had higher carotid-femoral pulse wave velocity values than normotensive individuals, and hypertensive patients with systolic blood pressure of ≤119mmHg (normotensive: 7.6±2.4m/s=≤119mmHg: 8.1±2.2m/s 120-129mmHg:9.8±2.6m/s=≥130mmHg: 9.9±2.9m/s, p<0.005). Sympathovagal balance was not associated with hypertension (p>0.05). CONCLUSION: Hypertensive patients with symptomatic peripheral artery disease have increased arterial stiffness. Arterial stiffness is even greater in patients with uncontrolled high blood pressure.

RESUMEN

BACKGROUND: Meta-analyses have demonstrated that isometric handgrip training (IHT) decreases blood pressure in hypertensive individuals. Nonetheless, most studies were conducted in laboratory settings and its effects in real-world settings remain unclear. OBJECTIVE: To analyze the effects of IHT on office and ambulatory blood pressure in hypertensive patients attended within primary healthcare. DESIGN AND SETTING: Randomized controlled trial conducted in primary healthcare units within the Family Health Program, Petrolina, Pernambuco, Brazil. METHODS: 63 hypertensive patients (30-79 years old; 70% female) were randomly allocated into IHT or control groups. IHT was performed three times per week (4 x 2 minutes at 30% of maximal voluntary contraction, one-minute rest between bouts, alternating the hands). Before and after the 12-week training period, office and ambulatory blood pressure and heart rate variability were obtained. The significance level was set at P < 0.05 (two-tailed testing) for all analyses. RESULTS: IHT significantly decreased office systolic blood pressure (IHT: 129 ± 4 versus 121 ± 3 mmHg, P < 0.05; control: 126 ± 4 versus 126 ± 3 mmHg, P > 0.05), whereas there was no effect on diastolic blood pressure (IHT: 83 ± 3 versus 79 ± 2 mmHg, P > 0.05; control: 81 ± 3 versus 77 ± 3 mmHg, P > 0.05). Heart rate variability and ambulatory blood pressure were not altered by the interventions (P > 0.05 for all). CONCLUSION: IHT reduced office systolic blood pressure in hypertensive patients attended within primary care. However, there were effects regarding diastolic blood pressure, ambulatory blood pressure or heart rate variability. CLINICALTRIALS.GOV IDENTIFIER: NCT03216317.

RESUMEN

BACKGROUND: This study aimed to analyze the effect of frailty on walking capacity and physical activity levels of patients with peripheral artery disease (PAD). METHODS: A cross-sectional study including 216 symptomatic PAD patients (e.g. claudication) was conducted. Moreover, the frailty profile was established, for which six-minute walk test, Walking Impairment Questionnaire (WIQ), and physical activity level were evaluated. RESULTS: Frailty was prevalent in 13.4%, 72.2%, and 14.4% of frail, pre-frail, and not-frail patients, respectively. Walking capacity was lower in frail patients than in not-frail patients (p < 0.024). The domains of distance and speed of WIQ were lower in frail patients than in not-frail patients, and these domains were also lower in pre-frail than in not-frail patients (p < 0.050 for all). The domain of stairs was lower in frail patients than in not-frail and pre-frail patients (p = 0.016). Physical activity levels were similar among groups (p > 0.050). CONCLUSION: Frailty is associated with further walking impairment in patients with PAD.

RESUMEN

BACKGROUND: Although 2-min step test (2MST) has been useful in general population, no study has investigated its validity in patients with peripheral artery disease (PAD). OBJECTIVE: To analyze the validity and reliability of the 2MST in patients with PAD and claudication symptoms. METHODS: Twenty-four patients with PAD and claudication symptoms were recruited and performed the 2MST comparing it to the six-minute walk test (6MWT). Test performance, step indicators, and heart rate were measured during the test. Validity was verified using Pearson correlation between the performance of 2MST (number of steps) and 6MWT (distance and number of steps). The reliability was analyzed by the intraclass correlation coefficient and by the limits of agreement of Bland and Altman. RESULTS: A similar performance was observed between the two 2MST (65 ±â€¯10 steps vs. 66 ±â€¯10 steps, p = 0.43) with a significant intraclass coefficient correlation of 0.945. The bias between tests was of 0.79 steps with the limits of agreement between -9.6 and 11.2 steps. The 90% minimum detectable difference was 3.2 steps. The number of steps in 2MST was significantly correlated with the number of steps in 6MWT (r = 0.55, p<0.01). However, the number of steps in 2MST did not correlate with distance in the 6MWT (r = 0.26, p = 0.23). The peak heart rate was lower in 2MST compared to 6MWT (p<0.05). CONCLUSION: The 2MST present adequate reliability and validity in patients with symptomatic PAD.

RESUMEN

OBJECTIVE: To describe physical activity habits and barriers for physical activity practice in patients with peripheral artery disease and claudication symptoms during Coronavirus 2019 (COVID-19) pandemic. METHODS: In this cross-sectional survey study, 127 patients with peripheral artery disease (59.8% men; 68±9 years old; and 81.9% had the peripheral artery disease diagnosis ≥5 years old) were included. The physical activity habits and barriers for physical activity practice were assessed through telephone interview using a questionnaire with questions related to: (a) COVID-19 personal care; (b) overall health; (c) physical activity habits; (d) for those who were inactive, the barriers for physical activity practice. RESULTS: Only 26.8% of patients reported practicing physical activity during the COVID-19 pandemic. Exercise characteristics more common among these patients include walking, performed at least 5 days a week, during 31-60 min at light intensity. In contrast, among physically inactive patients, pain, injury or disability (55%), the COVID-19 pandemic (50%), the need to rest due to leg pain (29%), and lack of energy (27%) were the most frequent barriers to physical activity practice. CONCLUSION: The physical activity level of patients with peripheral artery disease is impacted by the COVID-19 pandemic.

RESUMEN

Background: Elevated screen time has been associated with addictive behaviors, such as alcohol and sugar intake and smoking. Considering the substantial increase in screen time caused by social isolation policies, this study aimed to analyze the association of increased screen time in different devices during the COVID-19 pandemic with consumption and increased desire of alcohol, smoking, and sweetened foods in adults. Methods: A sample of 1,897 adults with a mean age of 37.9 (13.3) years was assessed by an online survey, being composed by 58% of women. Participants were asked whether screen time in television, cell phone, and computer increased during the pandemic, as well as how much time is spent in each device. Closed questions assessed the frequency of alcohol and sweetened food consumption, smoking, and an increased desire to drink and smoke during the pandemic. Educational level, age, sex, feeling of stress, anxiety, depression, and use of a screen device for physical activity were covariates. Binary logistic regression models considered adjustment for covariates and for mutual habits. Results: Increased television time was associated with increased desire to drink (OR = 1.46, 95% CI: 1.12; 1.89) and increased sweetened food consumption (OR = 1.53, 95% CI: 1.18; 1.99), while an increase in computer use was negatively associated with consumption of alcohol (OR = 0.68, 95% CI: 0.53; 0.86) and sweetened foods (OR = 0.78, 95% CI: 0.62; 0.98). Increased cell phone time was associated with increased sweetened food consumption during the pandemic (OR = 1.78, 95% CI: 1.18; 2.67). Participants with increased time in the three devices were less likely to consume sweetened foods for ≥5 days per week (OR = 0.63, 95% CI: 0.39; 0.99) but were twice as likely to have sweetened food consumption increased during pandemic (OR = 2.04, 95% CI: 1.07; 3.88). Conclusion: Increased screen time was differently associated with consumption and desire for alcohol and sweets according to screen devices. Increased time in television and cell phones need to be considered for further investigations of behavioral impairments caused by the pandemic.

RESUMEN

BACKGROUND: To examine the associations between physical activity (PA) and sedentary behavior (SB) with walking capacity and the effects of reallocating time from SB to PA in patients with symptomatic peripheral artery disease (PAD) using compositional data analysis. METHODS: This cross-sectional study included 178 patients (34% females, mean age = 66 [9] y, body mass index = 27.8 [5.0] kg/m2, and ankle-brachial index = 0.60 [0.18]). Walking capacity was assessed as the total walking distance (TWD) achieved in a 6-minute walk test, while SB, light-intensity PA, and moderate to vigorous-intensity PA (MVPA) were measured by a triaxial accelerometer and conceptualized as a time-use composition. Associations between time reallocation among wake-time behaviors and TWD were determined using compositional isotemporal substitution models. RESULTS: A positive association of MVPA with TWD (relative to remaining behaviors) was found in men (ßilr = 66.9, SE = 21.4, P = .003) and women (ßilr = 56.5, SE = 19.8; P = .005). Reallocating 30 minutes per week from SB to MVPA was associated with higher TWD in men (6.7 m; 95% confidence interval, 2.6-10.9 m) and women (4.5 m; 95% confidence interval, 1.5-7.5 m). CONCLUSIONS: The findings highlight, using a compositional approach, the beneficial and independent association of MVPA with walking capacity in patients with symptomatic PAD, whereas SB and light-intensity PA were not associated.

RESUMEN

OBJECTIVE: To investigate the impact of the coronavirus 2019 pandemic on physical activity levels and sedentary behavior among Brazilians residents aged ≥18 years. METHODS: An online survey was distributed through a social media platform between May 5 and 17, 2020. Participants completed a structured questionnaire in Google Forms, which assessed the physical activity level and sedentary behavior of adults in Brazil during the pandemic. RESULTS: Age (OR: 0.98; 95%CI: 0.97-0.99), chronic disease (OR: 1.29; 95%CI: 1.03-1.63), physical inactivity before the coronavirus 2019 pandemic (OR: 2.20; 95%CI: 1.78-2.72) and overweight (OR: 1.34; 95%CI: 1.09-1.65) showed higher risk of impact on physical activity levels. Increased sitting time was associated with older individuals (OR: 0.97; 95%CI: 0.96-0.98), inactivity (OR: 1.51; 95%CI: 1.16-1.96), chronic disease (OR: 1.65; 95%CI: 1.23-2.22), higher number of days in social isolation (OR: 1.01; 95%CI: 1.00-1.02) and higher schooling levels (OR: 1.87; 95%CI: 1.26-2.78). CONCLUSION: Our results demonstrated that advanced age, chronic disease and physical inactivity before social isolation had a greater risk of impact on reduced physical activity levels and increased sitting time during the coronavirus 2019 disease pandemic.

RESUMEN

Randomized controlled trials are known to be the best tool to determine the effects of an intervention; however, most healthcare professionals are not able to adequately understand the results. In this report, concepts, applications, examples, and advantages of using visual data as a complementary tool in the results section of original articles are presented. Visual simplification of data presentation will improve general understanding of clinical research.
