Body height has been recently related to the risk of coronary heart disease and metabolic risk factors. However, data are scarce regarding the relationship between body height and early-stage atherosclerotic changes, especially in Chinese individuals. In this study, we aimed to comprehensively examine the associations of body height with early-stage atherosclerosis and blood pressure in Chinese adults. Carotid-femoral pulse wave velocity (cfPWV), carotid-radial pulse wave velocity (crPWV), carotid artery-dorsalis pedis pulse wave velocity (cdPWV), and body height were measured in 5098 men and women. All samples were obtained from a community-based health examination survey in central China. After adjusting for sex, age, weight, fasting glucose level, lipid level, creatinine, and heart rate, low body heights were significantly associated with higher cfPWV, crPWV, and blood pressure (all P for trend <.01), whereas no significant association was found between body height and cdPWV. In addition, we found a significant interaction between prehypertension status and body height in relation to cfPWV, after adjusting for covariates (P for interaction = .0024). The associations were stronger in participants with prehypertension than in those with normal blood pressure. Compared to the group with the tallest stature and normal blood pressure, individuals in the group with the shortest stature and prehypertension had nearly a 2.5 m/s higher cfPWV. These results indicate that short body height was associated with an increased risk of early-stage atherosclerosis in Chinese adults, independent of traditional cardiometabolic risk factors. Prehypertension might modify the association between body height and cfPWV.
