ABSTRACT Childhood obesity is a major public health threat with rates increasing at an alarming rate worldwide. Currently 22.4% of children and adolescents are obese, approximately 16.7 million, with rates of obesity increasing in all age groups in the pediatric population. Obese children are more likely to be diagnosed with several major morbidities (hypertension, hyperlipidemia, coronary artery disease, and diabetes). The estimated annual health care costs of obesity- related illness are a staggering $190.2 billion or nearly 21% of annual medical spending in the United States. Household air pollution (HAP) is a term that describes the health and environmental impacts of pollutants produced from incomplete combustion of solid fuels such as wood, coal, charcoal, animal dung, crop wastes burnt on open fires or wood-burning stoves in poorly ventilated homes and releases suspended particulate matter (PM). There are few studies examining the role of household air pollution including PM2.5 in cardiovascular risk in the setting of pediatric obesity. An important component of cardiovascular health is a diurnal variation of blood pressure, where nocturnal levels are approximately 20% lower than daytime values. The absence of nocturnal BP-dipping in childhood may be an important indicator of early disease risks and our team has recently published evidence that childhood obesity is associated with non-dipping. The specific project proposed here will test the hypothesis that exposure to household air pollution increases cardiovascular risk in obese children through an inflammation- related disruption in diurnal BP regulation. This project will recruit patients aged 10-18 to define relationships between at-home air quality and hypertension risk factors. A pilot study to determine the impact of high efficacy particulate matter (HEPA) filtration units on air quality exposure and health risks will be measured in these patients as well. This research addresses a significant public health issue by understanding and identifying environmental exposures in a vulnerable high-risk group of rural children in order to develop new treatments to improve their health.

抽象的 儿童肥胖是主要的公共卫生威胁，费率以惊人的速度增加 全世界。目前有22.4％的儿童和青少年肥胖，约1670万， 小儿人群中所有年龄段的肥胖率随着肥胖率的增加。肥胖的孩子是 更有可能被诊断出患有几种主要病毒（高血压，高脂血症， 冠状动脉疾病和糖尿病）。肥胖的估计年度医疗保健费用 - 相关疾病是惊人的1,902亿美元，或近21％的年度医疗支出 美国。家庭空气污染（HAP）是一个描述健康和 固体燃料不完全燃烧产生的污染物的环境影响，例如 木材，煤炭，木炭，动物粪便，在露天大火或燃木炉子上燃烧的农作物浪费 通风不良并释放悬浮的颗粒物（PM）。很少有研究 检查家庭空气污染的作用，包括PM2.5在心脏血管风险中 小儿肥胖。心血管健康的重要组成部分是 血压，夜间水平比白天值低20％。这 儿童期缺乏夜间BP浸泡可能是早期疾病的重要指标 风险和我们的团队最近发表了证据，表明儿童肥胖与 非浸水。这里提出的具体项目将检验以下假设 家庭空气污染通过炎症增加了肥胖儿童的心血管风险 - 昼夜BP调节中的相关破坏。该项目将招募10-18岁的患者定义 在家空气质量与高血压风险因素之间的关系。试点研究 确定高效颗粒物（HEPA）过滤单元对空气质量的影响 这些患者也将测量暴露和健康风险。这项研究解决了 通过理解和确定环境暴露的重大公共卫生问题 脆弱的高风险农村儿童群体，以开发新的治疗方法以改善其 健康。
