Substance Use and Other Health Consequences Among Katrina Evacuees in Houston

描述（由申请人提供）：本研究将研究与卡特里娜飓风有关的灾难相关经历如何影响休斯顿低收入，主要是非裔美国人撤离者的物质使用和滥用模式，药物治疗利用，艾滋病毒风险行为和网络以及当前健康状况的变化。报告显示，超过15万人从受灾地区重新安置到休斯顿。这项研究将提供一个概念框架来解释物质使用和滥用，行为和其他与健康相关的后果与卡特里娜飓风的灾难相关的经验。此外，该研究将提供有关自然灾害后药物和性风险行为以及与药物使用和滥用相关的风险网络的信息，这些信息可能对人类免疫缺陷病毒（HIV）和其他传染病的传播产生严重后果。该应用程序建议在灾难发生8个月后收集300名卡特里娜撤离者的样本调查数据，这些撤离者目前居住在休斯顿大都市区。此外，还提议进行人种学观察和75次深入访谈，并进行为期6个月的后续访谈。本研究采用多元风险因素模型和多方法方法，研究药物使用和滥用模式、药物治疗利用、性和药物HIV及相关感染风险行为和风险网络特征与当前健康状况和意愿的结果。提供详细的检查和撤离者的灾难相关经历，因为卡特里娜飓风和相关的心理困扰，其他个人创伤和研究结果；2. 具体说明灾前风险因素与当前结果之间的关系是如何由灾后风险因素介导的；3. 说明灾后心理和其他个人创伤风险因素如何调节灾后风险因素与当前结果的关系，以及灾前风险因素的影响修正。4. 描述再安置吸毒者的社会网络、吸毒网络和性自我中心网络的网络特征以及这些网络的混合模式的程度；5. 通过使用人种学方法，确定卡特里娜飓风破坏、稳定或以其他方式影响药物获取、药物使用模式、获得和利用药物治疗服务的程度，以及社会进程和环境的影响。

DESCRIPTION (provided by applicant): This study will examine how disaster related experiences associated with Hurricane Katrina impact changes in substance use and abuse patterns, drug treatment utilization, HIV risk behaviors and networks, and current health status among low income, predominantly African American evacuees living in Houston. Reports indicate that over 150,000 individuals were relocated to Houston from the disaster stricken areas. This research will provide a conceptual framework to explain substance use and abuse, behavioral, and other health related consequences associated with the disaster related experiences of Hurricane Katrina. In addition, this research will provide information on the drug and sexual risk behaviors and risk networks associated with substance use and abuse after natural disasters that can have serious consequences for the spread of Human Immunodeficiency Virus (HIV) and other infectious diseases This application proposes to collect survey data on a sample of 300 drug using Katrina evacuees currently living in the greater Houston metropolitan area 8 months after the disaster. In addition, ethnographic observations and 75 in-depth interviews with a six-month follow-up interview are being proposed to be conducted with a sub-sample. Using the Multivariate Risk Factor Model and a multi-method approach, this study will examine the outcomes of substance use and abuse patterns, drug treatment utilization, sexual and drug HIV and related-infection risk behaviors and risk network characteristics and current health status and will: 1. Provide a detailed examination and the evacuees' disaster related experiences as a result of Hurricane Katrina and the associated psychological distress, other personal trauma and study outcomes; 2. Specify how the relationship between pre-disaster risk factors and current outcomes are mediated by post-disaster risk factors; 3. Specify how the relationship of within-disaster risk factors and current outcomes are mediated by post-disaster risk factors of psychological and other personal trauma, and the effect modification of pre-disaster risk factors. 4. Describe the network characteristics of the relocated drug users' social, drug use and sexual egocentric networks and the extent to which the mixing patterns of these networks; 5. Determine, through the use of ethnographic methods, the extent to which Hurricane Katrina disrupted, stabilized, or influenced in some other manner drug acquisition drug use patterns, and access to and utilization of drug treatment services and the influence of social processes and context.
