Short stature is reportedly associated with cardiovascular disease (CVD). However, the mechanism underlying this intriguing epidemiological finding is unclear. Pulse wave velocity (PWV), a marker of vascular stiffness, is a predictor of future CVD. Therefore, PWV may be affected by height even before overt CVD occurs. Here, we investigated the association between adult height and PWV in subjects without overt CVD.A total of 1019 subjects (48 ± 12 years old; 509 men, 21 with diabetes mellitus, 209 with hypertension) without overt CVD were enrolled, all of whom underwent brachial-ankle PWV (baPWV) measurements. The subjects were divided into 3 groups by height. A multiple regression model was used to estimate baPWV values among heights after the adjustment for confounders.Mean baPWV value was highest in the group with the shortest height for both sexes (both P < .001). Bivariate correlation analysis between height and baPWV showed significant correlations in men (r = -0.131, P = .003) and women (r = -0.180, P < .001). In the multiple regression analysis with adjustment for identified confounders, group height was a predictor of baPWV (P for trend = .003) in younger men (<50 years old) but not in older men, while group height was correlated with baPWV in older women (≥50 years old, P for trend = .014) but not in younger women.Height is inversely correlated with baPWV in subjects without overt CVD, especially in younger men and older women. This may explain the historical epidemiological observation of an inverse relationship between height and CVD.
据报道,身材矮小与心血管疾病(CVD)有关。然而,这一有趣的流行病学发现背后的机制尚不清楚。脉搏波速度(PWV)是血管僵硬度的一个指标,是未来心血管疾病的一个预测因子。因此,即使在明显的心血管疾病发生之前,PWV也可能受到身高的影响。在这里,我们研究了无明显心血管疾病的受试者中成人身高与PWV之间的关联。
共纳入1019名无明显心血管疾病的受试者(48±12岁;509名男性,其中21名患有糖尿病,209名患有高血压),所有受试者均进行了臂踝脉搏波速度(baPWV)测量。受试者按身高分为3组。采用多元回归模型在调整混杂因素后估计不同身高组的baPWV值。
男女身高最短组的平均baPWV值最高(均P<0.001)。身高与baPWV的双变量相关性分析显示,男性(r=-0.131,P=0.003)和女性(r=-0.180,P<0.001)之间存在显著相关性。在调整已识别混杂因素的多元回归分析中,身高分组是年轻男性(<50岁)baPWV的预测因子(趋势P=0.003),但老年男性中不是,而身高分组与老年女性(≥50岁,趋势P=0.014)的baPWV相关,但年轻女性中不是。
在无明显心血管疾病的受试者中,身高与baPWV呈负相关,尤其是在年轻男性和老年女性中。这可能解释了身高与心血管疾病之间负相关的历史流行病学观察结果。
