Description

<p>Preventing cardiovascular disease (CVD) is an urgent public health challenge. Although brachial-ankle pulse wave velocity (baPWV) can indicate the risk of arterial stiffness and CVD, findings regarding whether baPWV is associated with smoking are inconsistent. This study considered the influence of smoking on arteriosclerosis, specifically focusing on secondhand smoke (SHS), and aimed to construct a strategy for preventing the worsening of arteriosclerosis. We recruited 295 male employees from five companies who had smoking habits such as being smokers, living with smokers, and exposure to SHS outside the home. We measured body composition and hemodynamics, including blood pressure and baPWV, and found that baPWV had significant positive correlations with age, smoking index, alcohol consumption, body-fat percentage, blood pressure, and heart rate, and significant negative correlations with height, fat-free mass, and lower-limb muscle mass. Moreover, baPWV showed a significant adverse effect on participants who had metabolic syndrome (MetS) risk factors such as hypertension, dyslipidemia, and diabetes. Multiple regression analysis showed that baPWV had significant positive relationships with age, height, MetS risk factors, cohabitation with smokers, blood pressure, and heart rate, and a significant negative relationship with lower-limb muscle mass. The same results were obtained when adjusting for current smoking status, smoking index, cohabitation with smokers at birth, and frequency of exposure to SHS outside the home. Exposure to tobacco smoke due to cohabitation with smokers increased baPWV regardless of the person’s smoking habits. Thus, to prevent an increase in baPWV in housemates and smokers, it is necessary for smokers to quit smoking.</p>
