Cardiovascular disease (CVD) is the leading cause of death in the United States. Women are more likely than men to present with advanced disease and experience higher CVD-related morbidity and mortality. Metabolic syndrome is a constellation of risk factors for Type 2 diabetes mellitus (T2DM) and CVD. Abdominal adiposity, a component of metabolic syndrome, is associated with insulin resistance and promotes an atherogenic inflammatory milieu. Cardiometabolic risk (CMR) encompasses metabolic syndrome and incorporates other risk factors such as lifestyle choices, gender, and genetics as risk factors for CVD yet still does not include more recently recognized physiological risk factors such as vitamin D deficiency or psychosocial risk factors such as perceived stress and lack of social support. Because a more comprehensive view of CVD risk factors may facilitate earlier identification and risk reduction, we undertook this exploratory pilot study to answer the question, How do healthy women with and without abdominal adiposity differ physiologically and psychosocially?. We recruited a total of 41 women for a single study visit and assessed a battery of baseline physiological and psychological measures. While the women in this study were free of any diagnoses associated with increased CMR, women with increased waist circumference (WC) exhibited significantly altered levels of several measures associated with impending CMR including insulin sensitivity, lipids, and adiponectin as well as lower social support. These findings suggest that a more comprehensive conceptualization of and refinement of measures for CMR may be useful for identifying and reducing CMR and ultimately CVD in women.
心血管疾病(CVD)是美国的主要死因。女性比男性更容易出现晚期疾病,并经历更高的 CVD 相关发病率和死亡率。代谢综合征是 2 型糖尿病(T2DM)和 CVD 的一系列危险因素。腹型肥胖是代谢综合征的一个组成部分,与胰岛素抵抗有关,并促进动脉粥样硬化性炎症环境。心脏代谢风险(CMR)包含代谢综合征,并纳入其他风险因素,如生活方式选择、性别和遗传作为 CVD 的风险因素,但仍不包括最近认识到的生理风险因素,如维生素 D 缺乏或心理社会风险因素,如感知压力和缺乏社会支持。由于对 CVD 风险因素的更全面了解可能有助于更早地识别和降低风险,我们进行了这项探索性试点研究,以回答这个问题:“有和没有腹型肥胖的健康女性在生理和心理社会方面有何不同?”。我们总共招募了 41 名女性进行单次研究访问,并评估了一系列基线生理和心理测量。虽然本研究中的女性没有任何与增加 CMR 相关的诊断,但腰围增加(WC)的女性表现出与即将发生的 CMR 相关的几个测量值的显著改变,包括胰岛素敏感性、脂质和脂联素,以及较低的社会支持。这些发现表明,对 CMR 的更全面概念化和措施的改进可能有助于识别和降低女性的 CMR 和最终 CVD。
