PROJECT SUMMARY Obesity is a critical public health issue, and is responsible for a growing prevalence of diverse comorbidities that reduce quality of life and increase mortality risk. Obesity is an important risk factor for chronic kidney disease (CKD) and cardiovascular disease (CVD). Upregulation of the renin-angiotensin- aldosterone system, heightened sympathetic nervous system activity, vascular stiffness, and release of inflammatory cytokines contribute to the increased risk of CKD and CVD in obese patients. Accordingly, obesity is highly associated with the development of hypertension. As adiposity increases, patients are prone to glomerular hyperfiltration, amplified renal sodium reabsorption, extracellular volume overload, and impaired natriuresis. Thus, patients with excess adipose tissue are often more physiologically complex than lean hypertensive patients, and are at greater risk for many adverse outcomes related to hypertension. Nonetheless, little is known about appropriate blood pressure goals or the effects of specific antihypertensive agents on degree of blood pressure control in obese patients. The objective of the proposed studies is to better understand 1) if adiposity influences the effect of antihypertensive class on degree of BP control, and 2) the effect that degree of BP control has on the development and progression of CKD and CVD in obese, hypertensive patients. We will use prospective 24- hour ambulatory blood pressure monitoring in addition to longitudinal analyses of retrospective electronic health record data from two extremely largescale health systems, taking into account time-updated exposures and confounders. We will also use the electronic health record data to assess if there is a difference in initial antihypertensive class selection or BP threshold for initiation of antihypertensive treatment in obese versus non-obese patients. Using a multidisciplinary approach, we anticipate that this design will facilitate future optimization of medical management of patients with obesity and hypertension. I am currently funded by an NIH F32 grant, with board certification in Internal Medicine and Nephrology, and a Masters of Science in Clinical Epidemiology from the University of Pennsylvania. The K23 Career Development Award will enable me to develop research aimed at optimizing the pharmacologic management of the millions of obese, hypertensive patients living in the United States. My previous experience and training in longitudinal analyses have prepared me to engage in the work proposed in the studies, and will compliment my proposed intensive education in patient-oriented hypertension research, advanced longitudinal analytic techniques, pharmacoepidemiologic methods, and cardiovascular epidemiologic outcomes research. With the support of my highly experienced mentorship team and the ample resources available at the University of Pennsylvania’s Center for Clinical Epidemiology and Biostatistics, my goal is to foster a career of enduring research as an independent physician scientist, and to become a leader in the field of renal hypertension.

项目摘要 肥胖是一个严重的公共卫生问题，是导致各种疾病日益流行的原因。 降低生活质量和增加死亡风险的合并症。肥胖是一个重要的危险因素， 慢性肾病（CKD）和心血管疾病（CVD）。肾素-血管紧张素- 醛固酮系统，交感神经系统活动增强，血管僵硬， 炎性细胞因子导致肥胖患者CKD和CVD风险增加。因此，委员会认为， 肥胖与高血压的发展高度相关。随着肥胖症的增加， 肾小球过度滤过，肾钠重吸收增强，细胞外容量超负荷， 尿钠排泄因此，脂肪组织过多的患者通常比瘦的患者在生理上更复杂 高血压患者的高血压，并在许多与高血压有关的不良后果的风险更大。 尽管如此，对于适当的血压目标或特定抗高血压药物的作用知之甚少 药物对肥胖患者血压控制程度的影响。 拟议研究的目的是更好地了解1）肥胖是否影响 降压类别对血压控制程度的影响，以及2）血压控制程度对血压控制程度的影响。 肥胖、高血压患者中CKD和CVD的发生和进展。我们会用24小时- 小时动态血压监测以及回顾性电子血压监测的纵向分析 两个规模极大的卫生系统的健康记录数据，考虑到随时间更新的接触情况 和混杂因素。我们还将使用电子健康记录数据来评估初始 肥胖患者开始抗高血压治疗的降压药物类别选择或血压阈值与 非肥胖患者。使用多学科的方法，我们预计这种设计将有助于未来 优化肥胖和高血压患者的医疗管理。 我目前由NIH F32资助，拥有内科和肾脏学的委员会认证， 宾夕法尼亚大学临床流行病学硕士。K23职业生涯 开发奖将使我能够开发旨在优化药理学管理的研究 数百万肥胖高血压患者中的一员我以前的经验和训练 在纵向分析中，我为从事研究中提出的工作做好了准备，并将予以赞扬 我提出的强化教育以患者为导向的高血压研究，先进的纵向分析 技术、药物流行病学方法和心血管流行病学结果研究。与 我经验丰富的导师团队的支持和充足的资源，在大学 宾夕法尼亚临床流行病学和生物统计学中心，我的目标是培养一个持久的职业生涯， 作为一名独立的医生科学家进行研究，并成为肾性高血压领域的领导者。
