Some of the country's highest rates of morbidity and mortality from cardiovascular disease are found in lower-income black communities in the rural Southeast. Research suggests these disparities originate in the early decades of life, and partly reflect the influence of broader socioeconomic forces acting on behavioral and biological processes that accelerate cardiovascular disease progression. However, this hypothesis has not been tested explicitly. Here, we examine metabolic syndrome (MetS) in rural black young adults as a function of their family's economic conditions before and after the Great Recession.
In an ongoing prospective study, we followed 328 black youth from rural Georgia, who were 16 to 17 years old when the Great Recession began. When youth were 25, we assessed MetS prevalence using the International Diabetes Federation's guidelines. The sample's overall MetS prevalence was 18.6%, but rates varied depending on family economic trajectory from before to after the Great Recession. MetS prevalence was lowest (10.4%) among youth whose families maintained stable low-income conditions across the Recession. It was intermediate (21.8%) among downwardly mobile youth (ie, those whose families were lower income before the Recession, but slipped into poverty). The highest MetS rates (27.5%) were among youth whose families began the Recession in poverty, and sank into more meager conditions afterwards. The same patterns were observed with 3 alternative MetS definitions.
These patterns suggest that broader economic forces shape cardiometabolic risk in young blacks, and may exacerbate disparities already present in this community.
在农村东南部的低收入黑人社区,心血管疾病的发病率和死亡率是全国最高的。研究表明,这些差异起源于生命的早期,部分反映了更广泛的社会经济力量对加速心血管疾病进程的行为和生物过程的影响。然而,这一假设尚未得到明确验证。在这里,我们研究了农村黑人年轻成年人的代谢综合征(MetS),作为其家庭在大衰退前后经济状况的函数。
在一项正在进行的前瞻性研究中,我们跟踪了来自佐治亚州农村的 328 名黑人青年,他们在大衰退开始时年龄在 16 到 17 岁之间。当年轻人 25 岁时,我们根据国际糖尿病联合会的指南评估了 MetS 的患病率。该样本的总体 MetS 患病率为 18.6%,但根据家庭经济轨迹的变化而有所不同。在大衰退期间,家庭经济状况保持稳定的低收入家庭的年轻人中,MetS 的患病率最低(10.4%)。向下流动的年轻人(即家庭在大衰退前收入较低,但陷入贫困的年轻人)的患病率处于中间水平(21.8%)。家庭在大衰退开始时就处于贫困状态,之后又陷入更贫困状态的年轻人的 MetS 发病率最高(27.5%)。使用 3 种替代 MetS 定义也观察到了相同的模式。
这些模式表明,更广泛的经济力量塑造了年轻黑人的心脏代谢风险,并可能加剧了该社区已经存在的差异。
