Abstract

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.
