A risky sex prevention intervention for middle school age minority girls

项目总结（见说明）： 黑人少女经常从事危险的性行为。这些行为是黑人女孩感染艾滋病毒的主要原因。危险的行为包括过早发生性行为，不使用避孕套，多个性伴侣，以及在性行为之前使用酒精或药物。针对这些行为的干预措施已经过测试，但没有一项措施能影响黑人女孩和妇女中艾滋病毒感染率的不成比例。这项研究的目的是推迟性行为的开始或减少黑人女孩的危险性行为。该提案旨在测试一种多组成部分、家庭一级、适合发展的、以社区为基础的干预措施，以利于：（目标1）推迟或减少危险性行为，（目标2）增加艾滋病毒知识、与母亲的沟通、种族自豪感、赋权、自尊和性自信，以及（目标3）改善母亲与女儿的沟通和联系以及对孕产妇的监测：两组设计将比较干预组和注意力控制组。样本将包括96名黑人中学生和96名她们的母亲。将提供为期12周的干预措施，加强母女关系，建立种族/民族自豪感，以帮助黑人女孩建立自尊和自信，并增强保护自己免受艾滋病毒感染的能力。采取干预措施的母亲举办的会议侧重于青少年发展、与女儿公开交流的价值以及女孩面临的与性有关的社会压力。注意对照组女孩和母亲接受为期12周的一般健康教育干预，重点是改善健康（例如，糖尿病、吸烟）。将在基线、术后、3个月和9个月随访时收集结局数据。分析：为了检查干预是否降低了性启动或从事危险性行为的可能性（目标1），将确定是否成功实现这一目标。对于目标2+3，将计算两组中每组的平均值，并比较每个测量值。将使用同时合并t置信区间来调整多个测量值，以估计组间差异的幅度。影响：一项有益的干预措施的结果将用于改变艾滋病毒预防科学，并在社区环境中进行翻译，以减少黑人女孩的危险性行为。

PROJECT SUMMARY (See instructions): Black adolescent girls often engage in risky sex behaviors. These behaviors are the primary reason that black girls contract HIV. Risky behaviors include having sex at an early age, sex without condoms, multiple partners, and using alcohol or drugs prior to sex. Interventions to address these behaviors have been tested; yet none has affected the disproportionate rate of HIV among black girls and women. The goal of the proposed study is to delay sex initiation or reduce risky sex behaviors among black girls. This proposal is to test a multi-component, family-level, developmentally appropriate, community-based intervention for benefit in: (Aim1) delaying or decreasing risky sex, (Aim2) increasing HIV knowledge, communication with mothers, racial pride, empowerment, self-esteem and sexual assertiveness, and (Aim3) improving mother's communication and bonding with daughters and maternal monitoring: A 2-group design will compare intervention and attention control groups. The sample will include 96 black middle school-aged girls and 96 of their mothers. A 12-week intervention will be provided enhancing mother-daughter relationships and building racial/ethnic pride to help black girls develop self-esteem and assertiveness and be empowered to protect against HIV. Intervention mothers have sessions focused on adolescent development, the value of open communication with daughters, and social pressures related to sex that girls face. Attention control group girls and mothers receive a 12-week general health education intervention focused on improving health (e.g., diabetes, smoking) in girls. Data will be collected at baseline, post, 3 and 9 month follow-up on outcomes. Analysis: To examine whether the intervention reduces the likelihood of sexual initiation or engaging in risky sex (Aim1), success or lack of success in achieving this will be determined. For Aims 2+3 means will be calculated for each of the two groups and compared for each measure. Simultaneous pooled-t confidence intervals to adjust for multiple measures will be used to estimate the magnitude of the difference between groups. Impact: The findings of a beneficial intervention will be used to change HIV prevention science and for translation across community settings to decrease risky sex among black girls.
