项目摘要

DESCRIPTION (provided by applicant): Pediatric health disparities in the area of asthma, obesity and cardiovascular fitness continue to exist. Specifically, asthma and obesity are highly prevalent co-morbid conditions that disproportionately affect ethnic minority and urban children. These conditions share pathophysiological (e.g., inflammatory mediators) and contextual (living in an urban neighborhood) correlates, which may increase the risk for both conditions. A key lifestyle behavior implicated in both asthma morbidity and obesity risk is physical activity. Some children with asthma tend to restrict overall activities, including physical activity, when symptoms are in poor control. Although stressors related to urban living may also serve as barriers to physical activity among this group, we know little about the potential cultural and contextual mechanisms that help explain the association between asthma and physical activity in ethnic minority children. This ancillary study offers a unique opportunity to examine the association between asthma, physical activity and cultural and contextual factors in a group of urban children who are followed as part of their participation in Project NAPS (Nocturnal Asthma and Performance in School (R01 HD057220; Koinis Mitchell, PI). Project NAPS includes three, 4-week assessment periods (Session 1, S2, & S3) over the course of one academic year. In this ancillary study, we will incorporate objectively measured physical activity, and perceptions of asthma, physical activity and context to the third assessment period (S3), and add a fourth assessment period (S4) to occur at the start of the following academic year. This additional time point will provide: 1) an opportunity to examine the co-occurrence of asthma and allergic rhinitis symptoms, physical activity, and sedentary behavior, and 2) an in depth examination (at S3 and S4) of potential cultural and contextual influences on physical activity in a sample of 150 children with persistent asthma who are overweight/obese or healthy weight. We hypothesize that children with more asthma and allergic rhinitis symptoms will participate in less moderate to vigorous physical activity (MVPA) and more sedentary activities. These associations will be more pronounced in children from Latino and AA backgrounds than in Non-Latino White children. We further hypothesize that fear related to asthma and perceptions of neighborhood safety will each be independent predictors of MVPA, and will predict activity levels beyond actual asthma symptom level and measured neighborhood characteristics. We also expect these associations will be more pronounced in caregivers from Latino and AA backgrounds. Finally, we hypothesize that caregivers' perception of exercise as a trigger for asthma will be related to less MVPA and more sedentary behavior. This association will be apparent even when accounting for children's actual exercise-induced brochospasm status (EIB). A similar pattern will be found for children's perceptions. This association will be more pronounced in caregivers and children of Latino and AA backgrounds. This line of research has significant implications for the development of cultural tailored interventions to: increase physical activity n urban children with persistent asthma; and improve caregiver understanding of asthma symptoms and exercise induced-bronchospasm. Ultimately, study findings could have implications for improving the standard of care for urban and ethnic minority children with persistent asthma.

描述（由申请人提供）：哮喘，肥胖和心血管健身领域的小儿健康差异继续存在。具体而言，哮喘和肥胖是高度普遍的合并症，对少数民族和城市儿童的影响不成比例。这些疾病具有病理生理（例如炎症介体）和情境（生活在城市社区）的相关性，这可能会增加两种情况的风险。与哮喘发病率和肥胖风险有关的关键生活方式行为是体育锻炼。当症状受到控制不佳时，一些哮喘患者倾向于限制包括体育活动在内的整体活动。尽管与城市生活有关的压力源也可能是该小组体育锻炼的障碍，但我们对潜在的文化和上下文机制知之甚少，这些机制有助于解释少数民族儿童哮喘与体育活动之间的关联。这项辅助研究提供了一个独特的机会，可以检查一群城市儿童哮喘，体育活动与文化和情境因素之间的关联，这些儿童被遵循的一部分是他们参与项目小睡的一部分（夜间哮喘和学校的表现（R01 HD057220； R01 HD057220; Koinis Mitchell，PI）。 ancillary study, we will incorporate objectively measured physical activity, and perceptions of asthma, physical activity and context to the third assessment period (S3), and add a fourth assessment period (S4) to occur at the start of the following academic year. This additional time point will provide: 1) an opportunity to examine the co-occurrence of asthma and allergic rhinitis symptoms, physical activity, and sedentary behavior, and 2) an in depth examination (at S3和S4）潜在的文化和情境影响对超重/肥胖或健康体重的150名持续性哮喘的儿童样本中的体育活动影响。我们假设患有更多哮喘和过敏性鼻炎症状的儿童将参加中等至剧烈的体育锻炼（MVPA）和更多久坐的活动。与非拉丁裔白人儿童相比，来自拉丁裔和AA背景的儿童和AA背景的孩子将更明显。我们进一步假设，与哮喘和邻里安全的看法有关的恐惧将是MVPA的独立预测因素，并将预测超出实际哮喘症状水平和测量邻居特征的活动水平。我们还希望这些关联在拉丁裔和AA背景的护理人员中会更加明显。最后，我们假设护理人员将运动作为哮喘的触发感与MVPA和更久坐的行为有关。即使考虑到儿童实际锻炼引起的小册子状态（EIB），这种关联也将是显而易见的。对于儿童的看法，也会发现类似的模式。在拉丁裔和AA背景的护理人员和子女中，该协会将更加明显。这项研究对文化量身定制的干预措施的发展具有重要意义：增加体育锻炼的持续性哮喘的城市儿童；并提高护理人员对哮喘症状的理解和锻炼诱导的支气管痉挛。最终，研究结果可能对改善持续性哮喘的城市和少数民族儿童的护理标准有影响。
