Factors Associated with Sedentary Behavior in Patients with Intermittent Claudication

Abstract

Objectives Time spent in sedentary behavior has been associated with cardiometabolic risk factor 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 of 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) have 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 of the sedentary time were male sex (b=0.217, R2=0.180, p=0.001), body mass index (b=0.154, R2=0.059, p=0.013), peak walking time (b=−0.360, R2=0.066, p=<0.001) and walking economy (b=−0.187, R2=0.142, p=0.004). 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.

The Impact of Supervised Exercise Training on Traditional Cardiovascular Risk Factors in Patients With Intermittent Claudication: A Systematic Review and Meta-Analysis

“…49 Moreover, walking interventions in a broad range of health conditions did not find any effect on HDL-C or triglycerides. 50,51 Next, obesity in IC patients is an important risk factor since it is directly associated with walking ability, 52 improvement during SET, 52,53 sedentary behaviour, 54 and subsequent development of other CV risk factors. 55 More specifically, this progression of CV risk factors is linked with body composition and the visceral distribution of fat mass.…”

Visual data: a new tool to improve the presentation of clinical trial results

“…Tertiles and quartiles: outcomes have no established cut-off points, and some studies have used arbitrary values based on the median, tertiles, quartiles or percentiles, which can be contested. ( 11 , 12 )…”

“…Tercis e quartis: os desfechos não têm pontos de corte estabelecidos, e alguns estudos usaram valores arbitrários baseados na mediana, em tercis, quartis ou percentis, o que poderia ser contestado. ( 11 , 12 )…”

The Active Supination Dorsiflexion Test Guided Therapeutic Intervention for Shin and Calf Pain: A Case Report

“…Lower leg, shin and calf pain are frequently encountered in rehabilitation settings. It is a condition prevalent in both active and sedentary individuals [1,2]. Individuals presenting to a primary care setting with lower leg, shin and calf pain are evaluated for the possible presence of blood clots [3], chronic exertional compartment syndrome (CECS) [4], stress fractures [5], and infrequently malignancy [6].…”
