DESCRIPTION (provided by applicant): The prevalence of asthma varies among communities in the United States. Within New York City (NYC), the reported prevalence of pediatric asthma and hospitalization rates for asthma vary markedly between adjacent neighborhoods. We hypothesize that the difference in the prevalence of asthma observed between neighborhoods in NYC is due to differences in exposure to asthma/allergy environmental triggers (indoor cockroach and mouse allergens, and local sources of diesel particulates), physical activity levels and high body mass index for age. To test this hypothesis, we propose to recruit 800 children age 7 years who reside in NYC and have been enrolled in the HIP health plan through a parent or guardian's employment since birth. The children will be recruited from two types of neighborhoods of approximately equal HIP population size, 1) high asthma prevalence (~16%) neighborhoods [HAPN] 2) lower asthma prevalence (~9%) neighborhoods [LAPN]. Children will be classified as asthmatic or non-asthmatic by telephone administration of the ISAAC survey plus report of asthma controller medication. Employing stratified quota sampling we will recruit an equal number of asthmatics (n=400) and randomly selected non-asthmatics (n=400) enrolled from the combined population of HAPN and LAPN children. The HIP sampling frame will yield a multi-ethnic sample of children from low- middle and middle income homes, all of whom have similar access to health care. We will include measures on SES, ethnicity and built environment in multivariate analyses to control for these potential confounders. This study will use the same measures that are being employed in three other asthma studies being conducted on children the same age who live neighborhoods of high asthma prevalence in NYC. Aim 1. We hypothesize that, compared to children living in LAPN; children living in HAPN will be 1a.) More exposed to cockroach and mouse allergens in the dust and to diesel particulate matter in the air, 1b.) More likely to be sensitized to cockroach and mouse allergens, and 1c.) More sedentary and have a higher body mass index for age. Aim 2. We hypothesize that among children with asthma in LAPN, children with asthma in HAPN will have 2a.) More severe asthma (as classified by symptoms and spirometry), 2b.) higher levels of exhaled nitric oxide, a measure of airway inflammation. Aim 3. We hypothesize that among children sensitized to at least one allergen (i.e., atopic), those who live in a HAPN will be more likely to have asthma than those who live in an LAPN.

描述（由申请人提供）：美国不同社区的哮喘患病率不同。在纽约市（NYC）内，报告的儿童哮喘患病率和哮喘住院率在相邻社区之间存在显著差异。我们假设，在纽约市的社区之间观察到的哮喘患病率的差异是由于暴露于哮喘/过敏环境触发因素（室内蟑螂和小鼠过敏原，以及柴油颗粒物的本地来源），体力活动水平和年龄的高体重指数的差异。为了检验这一假设，我们建议招募800名7岁的儿童，他们居住在纽约市，并从出生起就通过父母或监护人的就业参加了HIP健康计划。儿童将从两类HIP人群规模大致相等的社区招募，1）哮喘患病率高（~16%）的社区[HAPN] 2）哮喘患病率较低（~9%）的社区[LAPN]。通过电话管理ISAAC调查加上哮喘控制药物报告，将儿童分类为哮喘或非哮喘。采用分层配额抽样，我们将招募相同数量的哮喘患者（n=400），并从HAPN和LAPN儿童合并人群中随机选择非哮喘患者（n=400）。HIP抽样框架将产生来自中低收入家庭的多种族儿童样本，所有这些儿童都有类似的保健机会。我们将在多变量分析中包括SES，种族和建筑环境的措施，以控制这些潜在的混杂因素。这项研究将使用与其他三项哮喘研究相同的措施，这些研究是在纽约市哮喘高发社区的同龄儿童中进行的。目标1.我们假设，与生活在LAPN的儿童相比，生活在HAPN的儿童将是1a。更多地暴露于灰尘中的蟑螂和老鼠过敏原以及空气中的柴油颗粒物，1b。更容易对蟑螂和老鼠过敏原过敏，和1c。更多的久坐不动，并有较高的身体质量指数的年龄。目标二。我们假设在LAPN的哮喘儿童中，HAPN的哮喘儿童将有2a。）更严重的哮喘（根据症状和肺功能测定法分类），2b.）呼出的一氧化氮水平更高，这是气道炎症的一个指标。目标3。我们假设，在对至少一种过敏原敏感的儿童中（即，特应性），生活在HAPN中的人比生活在LAPN中的人更容易患哮喘。
