African-American adolescents living in high-risk inner-city environments have been disproportionately affected by the epidemics of human immunodeficiency virus (HIV) and other sexually transmitted diseases. Understanding the factors that influence the use of condoms by adolescents is critical for developing effective behavioral interventions. The present study examined the demographic, psychosocial, and behavioral correlates of condom use among African-American adolescents residing in public housing developments in an HIV epicenter (San Francisco) and prospectively evaluated the stability of these significant cross-sectional variables to predict consistent condom use.
A prospective study.
Two public housing developments in San Francisco.
African-American adolescents and young adults between 12 and 21 years of age were recruited though street outreach and completed a theoretically derived research interview assessing HIV-related knowledge, attitudes, and behaviors. After a 6-month period, adolescents completed a follow-up interview similar to the baseline measure. Among adolescents reporting sexual activity in the 6 months before completing the baseline interview (n = 116), logistic regression analysis evaluated the influence of demographic, psychosocial, and behavioral factors on consistent condom use.
Adolescents who had high assertive self-efficacy to demand condom use (adjusted odds ratio [OR], 11), perceived peer norms as supporting condom use (OR, 4.2), had greater impulse control (OR, 3.7), were male (OR, 4.7), and were younger (OR, 2.9) were more likely to report consistent condom use. Frequency of sexual intercourse was inversely related to condom use; adolescents with higher numbers of sexual episodes were less likely to use condoms consistently. Prospective analyses identified the baseline level of condom use as the best predictor of condom use at the 6-month follow-up. Adolescents who were consistent condom users at baseline were 7.4 times as likely to be consistent condom users during the follow-up period. Of those adolescents changing their frequency of condom use during the follow-up interval, significantly more engaged in risky behavior; 33.3% changed from consistent to inconsistent condom use, whereas 20.6% changed from inconsistent to consistent use (OR, 1.6).
The findings suggest that HIV prevention programs need to be implemented early, before high-risk behaviors are established and may be more difficult to modify.
生活在高风险市中心城区环境中的非裔美国青少年受人类免疫缺陷病毒(HIV)及其他性传播疾病流行的影响尤为严重。了解影响青少年使用避孕套的因素对于制定有效的行为干预措施至关重要。本研究调查了居住在HIV高发区(旧金山)公共住房开发区的非裔美国青少年使用避孕套的人口统计学、心理社会及行为学相关因素,并前瞻性评估了这些显著的横断面变量预测持续使用避孕套的稳定性。
前瞻性研究。
旧金山的两个公共住房开发区。
通过街头宣传招募了年龄在12至21岁之间的非裔美国青少年和青年,并完成了一项基于理论推导的研究访谈,评估与HIV相关的知识、态度和行为。6个月后,青少年完成了一次与基线测量类似的随访访谈。在完成基线访谈前6个月内有性行为的青少年(n = 116)中,逻辑回归分析评估了人口统计学、心理社会和行为因素对持续使用避孕套的影响。
对要求使用避孕套有高度自信自我效能感的青少年(调整优势比[OR],11)、认为同伴规范支持使用避孕套的青少年(OR,4.2)、有更强冲动控制能力的青少年(OR,3.7)、男性青少年(OR,4.7)以及年龄较小的青少年(OR,2.9)更有可能报告持续使用避孕套。性交频率与避孕套使用呈负相关;性交次数较多的青少年持续使用避孕套的可能性较小。前瞻性分析确定基线时的避孕套使用水平是6个月随访时避孕套使用的最佳预测指标。基线时持续使用避孕套的青少年在随访期间持续使用避孕套的可能性是其他青少年的7.4倍。在随访期间改变避孕套使用频率的青少年中,从事危险行为的比例显著更高;33.3%的青少年从持续使用变为不持续使用避孕套,而20.6%的青少年从不持续使用变为持续使用(OR,1.6)。
研究结果表明,HIV预防项目需要在高风险行为形成之前尽早实施,因为高风险行为一旦形成可能更难改变。
