项目摘要

DESCRIPTION (provided by applicant): Asthma has reached epidemic proportions in the United States and African-Americans fare worse than whites on all measures of asthma morbidity. Reasons for the disparity have not been satisfactorily explained. Psychosocial factors like experiences of violence and living in disadvantaged and/or inner city neighborhoods have been found to play a role in childhood asthma prevalence and severity. While the role of psychosocial factors in asthma expression has been studied in children there is little research on such factors in adults. Stress is the putative mechanism and there are plausible biological mechanisms by which it may contribute to the incidence of adult-onset asthma. Psychosocial factors may be of particular importance in asthma incidence in black women because the prevalence of experiences of violence, racism, depression, and living in disadvantaged neighborhoods are higher than in white women. If such experiences increase the risk of adult onset asthma, they may contribute to the racial disparity in asthma morbidity. The objective of this application is to fill this gap in knowledge about the role of psychosocial factors in incident adult-onset asthma in African American women. Our central hypothesis is that individual- and neighborhood-level psychosocial factors that may lead to stress increase the risk of adult-onset asthma in African-American women. The rationale for the proposed research is that the identification of factors that increase the risk of adult-onset asthma is a necessary step in the development of preventive policies and interventions to reduce both levels of adult-onset asthma and the gap in black/white asthma morbidity. The specific aims of this application are to 1) estimate the influence of experiences of racism, experiences of violence during childhood and adolescence, and depressive symptoms to asthma incidence and 2) to estimate the influence of neighborhood socioeconomic status (SES), racial segregation, and urbanicity to asthma incidence. We will conduct prospective analyses using data from the Black Women's Health Study (BWHS). The BWHS cohort, assembled in 1995, includes approximately 59,000 African-American women from across the U.S. Detailed information on demographics, medical and reproductive history, and disease endpoints including asthma, was collected at baseline and in biennial follow- up questionnaires. On selected follow-up questionnaires, information was obtained on the psychosocial factors of interest. Participant addresses have been geocoded and linked with census data. Over 16 years of follow-up through 2011, approximately 1800 incident cases of asthma will have been reported. The study is innovative because it will be the first prospective study to consider the effects of the psychosocial exposures of interest on incident adult asthma in African American women. The proposed research is significant because positive results may direct intervention efforts to address stressors like racism and violence and may motivate further mechanistic studies of how chronic stress leads to asthma, which might inform the development of new therapeutic interventions. PUBLIC HEALTH RELEVANCE: The proposed research will identify psychosocial factors that contribute to asthma incidence in African American women and thus will fill gaps in knowledge about risk factors for adult-onset asthma and about reasons for the racial disparity in asthma morbidity in the US. Results from the proposed study have the potential to inform preventive strategies at the individual and societal level. Thus the proposed research is relevant to the part of NIH's mission that seeks to extend healthy life and reduce the burdens of illness and disability.
描述(由申请人提供):哮喘在美国已达到流行病的比例,非洲裔美国人在哮喘发病率的所有指标上都比白人差。造成这种差异的原因尚未得到令人满意的解释。社会心理因素,如暴力经历和生活在弱势和/或内城社区已被发现在儿童哮喘的患病率和严重程度中发挥作用。虽然已经在儿童中研究了心理社会因素在哮喘表达中的作用,但在成人中对这些因素的研究很少。应激是公认的机制,并且存在可能的生物学机制,其可能有助于成人发作哮喘的发病率。心理社会因素在黑人女性哮喘发病率中可能特别重要,因为暴力、种族主义、抑郁和生活在弱势社区的经历的患病率高于白色女性。如果此类经历增加了成人发作哮喘的风险,则可能会导致哮喘发病率的种族差异。本申请的目的是填补这方面的知识空白,心理社会因素的作用,在事件成人发作的哮喘在非洲裔美国妇女。我们的中心假设是,可能导致压力的个人和社区水平的心理社会因素增加了非洲裔美国妇女成年期哮喘发作的风险。提出这项研究的理由是,确定增加成人发作哮喘风险的因素是制定预防政策和干预措施以减少成人发作哮喘水平和黑人/白色哮喘发病率差距的必要步骤。本申请的具体目的是:1)估计种族主义经历、儿童期和青少年期暴力经历以及抑郁症状对哮喘发病率的影响; 2)估计社区社会经济地位(SES)、种族隔离和城市化对哮喘发病率的影响。我们将使用黑人妇女健康研究(BWHS)的数据进行前瞻性分析。1995年收集的BWHS队列包括来自美国各地的约59,000名非洲裔美国妇女。在基线和两年一次的随访问卷中收集了关于人口统计学、病史和生殖史以及疾病终点(包括哮喘)的详细信息。在选定的后续调查问卷中,获得了有关感兴趣的心理社会因素的信息。参与者的地址已作地理编码,并与普查数据相联系。在截至2011年的16年随访中,将报告约1800例哮喘事件。这项研究是创新的,因为它将是第一个前瞻性研究,考虑到感兴趣的心理社会暴露对非洲裔美国妇女成人哮喘事件的影响。拟议的研究是重要的,因为积极的结果可能会指导干预工作,以解决种族主义和暴力等压力源,并可能激励进一步的机制研究慢性压力如何导致哮喘,这可能会为新的治疗干预措施的发展提供信息。 公共卫生相关性:这项拟议的研究将确定导致非洲裔美国妇女哮喘发病率的心理社会因素,从而填补有关成人发作哮喘风险因素和美国哮喘发病率种族差异原因的知识空白。拟议研究的结果有可能为个人和社会层面的预防战略提供信息。因此,拟议中的研究与NIH的部分使命相关,该使命旨在延长健康寿命,减少疾病和残疾的负担。
