PS07-003, Minority HIV/AIDS Research Initiative (MARI)

描述（由申请人提供）：拟议的研究项目将使用定量和定性数据来探索与男性发生性关系的年轻（18-30 岁）黑人男性 (BMSM) 遇到其他男性并进行性行为的社会和情境背景的特征。该研究将侧重于了解与风险行为相关的背景因素。情境因素以两种方式概念化：1）与性冒险行为近端相关的因素（即近端风险因素，例如性活动期间的物质使用、性伴侣和环境的特征、对性伴侣的感受以及与性伴侣的沟通），以及2）与性冒险行为远端相关的因素（即远端风险因素，例如儿童和青少年暴露于赤贫、父母或照顾者的物质使用、和/或暴力和创伤）。该研究还将探讨年轻 BMSM 中与艾滋病毒保护行为相关的弹性以及其他个人和社会因素，并描述该人群中有效艾滋病毒预防和治疗的障碍和促进因素。这项工作的总体目标是帮助确定针对年轻 BMSM 的预防信息和个人、团体和社区层面干预措施的潜在有效组成部分。定性数据将来自对 50 名年轻黑人 MSM 进行的生活史访谈。定量数据将通过横断面调查和纵向、基于互联网的结构化每周日记收集，由 200 名年轻 BMSM 完成。这项拟议的研究通过研究可能使年轻 BMSM 面临艾滋病毒高风险的因素，对公共健康具有重要意义。针对这一人群开展的大规模研究项目很少，并且只设计了少量干预措施来有效影响这一人群。该项目采用概念和分析方法，重点描述年轻 BMSM 中性冒险行为的背景。通过采用这种方法，我们能够更好地确定有效的预防信息，并确定针对年轻 BMSM 的个人、群体和社区层面干预措施的必要组成部分。

DESCRIPTION (provided by applicant): The proposed research project will use quantitative and qualitative data to explore features of the social and situational contexts in which young (18-30 yrs old) Black men who have sex with men (BMSM) meet other men and engage in sexual behaviors. The research will focus on understanding the contextual factors associated with risk behavior. Contextual factors are conceptualized in two ways: 1) those proximally linked to sexual risk-taking (i.e., proximal risk factors, such as substance use during sexual activity, characteristics of sex partners and settings, feelings toward sex partners, and communication with sex partners), and 2) those distally related to sexual risk-taking (i.e., distal risk factors, such as childhood and adolescent exposure to abject poverty, substance use by parents or caregivers, and/or violence and trauma). The research will also explore resiliency and other personal and social factors associated with HIV protective behaviors among young BMSM, as well as describe the barriers and facilitators to effective HIV prevention and treatment in this population. The overarching goal of the work is to aid in the identification of potentially effective components of prevention messages and individual-, group-, and community-level interventions directed toward young BMSM. Qualitative data will be derived from life history interviews conducted with 50 young Black MSM. Quantitative data will be collected through a cross-sectional survey and a longitudinal, Internet-based structured weekly diary that 200 young BMSM will complete. The proposed study has great significance to public health, by examining the factors that that may place young BMSM at heightened risk for HIV. Few large-scale research projects have been conducted with this group, and only a small number of interventions have been designed that effectively reach this population. The project takes a conceptual and analytical approach that focuses on describing the contexts of sexual risk-taking behavior among young BMSM. By taking this approach, we are better able to ascertain effective prevention messages, and to identify the necessary components of individual-, group-, and community-level interventions directed toward young BMSM.
