RESUMO
BACKGROUND: The Vascular Quality of Life Questionnaire (VascuQoL-6) was proposed to evaluate specific quality of life of peripheral artery disease (PAD) patients. However, there is no Brazilian-Portuguese version available, blunting its use in Brazilian patients. The objective of the study was to analyze the psychometric properties of a translated Brazilian-Portuguese version of VascuQoL-6 in Brazilian patients with PAD with intermittent claudication symptoms. METHODS: One hundred eleven patients with PAD participated in the study. After translation and retranslation, construct validity was analyzed by identifying correlation between VascuQoL-6 scores, general World Health Organization qualify of life (WHOQOL) score, and subjective and objective functional capacity tests. To determine the reliability, internal consistency and test-retest reliability with at least 7 days interval between 2 questionnaire applications were calculated. RESULTS: Significant correlations between the VascuQoL-6 score and total WHOQOL score (r = 0.44; P < 0.05) were observed. Moreover, we observed negative correlations between the VascuQoL-6 score and 4-meter usual pace (r = -0.33; P < 0.05) and 4-meter fast pace (r = -0.34; P < 0.05) and positive correlation with onset claudication distance (r = 0.39; P < 0.05) and total walking distance (r = 0.29; P ≤ 0.05). Internal consistency was 0.84, whereas the intraclass coefficient correlation was 0.84, with no differences in VascuQoL-6 scores between the 2 applications days. CONCLUSIONS: The Brazilian-Portuguese version of the VascuQoL-6 presents adequate valid and reliability indicators, allowing its use in patients with PAD with intermittent claudication symptoms.

OBJECTIVES: Time spent in sedentary behavior has been associated with cardio-metabolic risk factors in the general population and in patients with symptomatic peripheral artery disease (PAD). Given the association of sedentary behavior and poor health outcomes, it is important to identify factors associated with sedentary behavior in these patients. The aim of this study was to identify factors associated with the sedentary time in patients with symptomatic PAD. METHODS: The sample included 297 patients with symptomatic PAD. Sedentary behavior was assessed using a step activity monitor and the patients were divided into tertiles. Demographic data, body mass index, comorbid conditions, and measures of severity of PAD (ankle brachial index, ischemic window, claudication measurements, peak oxygen uptake and walking economy) were obtained. RESULTS: Patients in the highest tertile (i.e. more sedentary) had a higher body mass index and a higher prevalence of diabetes mellitus, metabolic syndrome, and obesity than patients in the lowest tertile, whereas their peak walking time, peak oxygen uptake, and walking economy were lower (p < .05 for all). Using multiple regression procedures, the factors associated with the sedentary time were male sex (b = .217, R2 = .180, p = .001), body mass index (b = .154, R2 = .059, p = .013), peak walking time (b = -.360, R2 = .066, p ≤ .001), and walking economy (b = -.187, R2 = .142, p = .004). CONCLUSION: In patients with symptomatic PAD, greater time spent in sedentary behavior was found in men, and in patients with higher body mass index, lower peak walking time, and lower walking economy.

OBJECTIVE: Time spent in sedentary behavior has been associated with worse inflammation and cardiometabolic biomarkers in various populations. However, the association between time spent in sedentary behavior and biomarkers remains unknown in patients with intermittent claudication. The aim of the current study was to analyze the relationship between sedentary behavior and inflammatory and cardiometabolic biomarkers in patients with symptomatic peripheral arterial disease (PAD). METHODS: The sample included 297 patients with intermittent claudication. Sedentary behavior was assessed using a step activity monitor. Biomarkers of inflammation, oxidative stress, lipid profile, insulin resistance, and endogenous fibrinolysis were assessed. Demographic data, body mass index, physical activity status, and measures of severity of PAD (ankle-brachial index, peak walking time, and ischemic window) also were obtained. RESULTS: Time spent in sedentary behavior was related with high-sensitivity C-reactive protein (b = 0.187; P = .005), glucose (b = 0.238; P < .001), fibrinogen (b = 0.167; P = .017), plasminogen activator inhibitor 1 activity (b = 0.143; P = .036), and high-density lipoprotein cholesterol (b = -0.133; P = .029). After adjustment for sex, age, physical activity status, body mass index, and severity of PAD, sedentary behavior remained related with high-sensitivity C-reactive protein (b = 0.170; P = .015), glucose (b = 0.178; P = .004), fibrinogen (b = 0.189; P = .010), and high-density lipoprotein cholesterol (b = -0.128; P = .032). CONCLUSIONS: Time spent in sedentary activities was associated with worse inflammatory and cardiometabolic profile in patients with intermittent claudication.
