['Altered arterial stiffness is a recognized risk factor of poor cardiovascular health. Chronic inflammation may increase arterial stiffness. We tested whether arterial stiffness is increased children with asthma, a chronic disease characterized by fluctuating airway and systemic inflammation. Arterial stiffness, expressed as carotid-femoral pulse wave velocity (PWVcf), was measured in 37 mild-to-moderate asthmatic children: 11 girls, median (range) age 11.1\xa0years (6-15). PWVcf in asthma was compared to PWVcf in 65 healthy controls matched for age, height, and gender previously studied in Germany and was correlated with airway inflammation and obstruction. PWVcf was higher in asthmatic children compared to controls: PWVcf median (interquartile range) was 4.7\xa0m/s (4.5-4.9) vs. 4.3\xa0m/s (4.1-4.7), p\u2009<\u20090.0001. In asthmatic children, PWVcf was inversely associated (r (2)\u2009=\u20090.20, p\u2009=\u20090.004) with forced expiratory volume in 1\xa0s (FEV1). This association remained significant after adjusting for possible confounders including body mass index, blood pressure, steroid use, and FeNO.'] Is arterial stiffness increased in asthmatic children?
