To evaluate an HIV risk-reduction intervention among Namibian adolescents.
A randomized trial of a 14-session face-to-face intervention emphasizing abstinence and safer sexual practices conducted among 515 youths (median age 17 years and median grade 11) attending 10 secondary schools located in two districts in Namibia. Youths were randomly assigned to the intervention or control condition at the level of the individual. HIV risk behaviours, intentions and perceptions were assessed at baseline, immediately post-intervention and at 6 and 12 months post-intervention.
Among all 515 youths who enrolled in the programme, rates of either abstinence or sex with a condom were not different between control and intervention youths at baseline or in the follow-up period. However, analyses conducted among the subset of youths who were sexually inexperienced at baseline (n = 255) revealed that a higher percentage of intervention youths (17%) than control youths (9%, P<0.05) remained sexually inexperienced one year later. Moreover, in the immediate post-intervention period, among baseline virgins who subsequently initiated sex, intervention youths were more likely than control youths to use a condom (18 versus 10%, P<0.05). Additional HIV-related risk behaviours (failure to discuss previous HIV risk exposure with one's sexual partner and alcohol use), intentions to use condoms, and perceptions of the ability to use condoms were positively affected by the intervention.
There is evidence that the 'My Future is My Choice' (MFMC) intervention is reducing HIV risk behaviours among sexually inexperienced participants aged 15-18. Related risk behaviours and perceptions are also positively impacted by the intervention.
评估纳米比亚青少年中一项降低艾滋病病毒感染风险的干预措施。
在纳米比亚两个地区的10所中学对515名青少年（年龄中位数17岁，年级中位数为11年级）开展一项随机试验，该干预措施为为期14节的面对面干预，重点强调禁欲和更安全的性行为。青少年在个体层面被随机分配到干预组或对照组。在基线期、干预刚结束后以及干预后6个月和12个月评估艾滋病病毒感染风险行为、意愿和认知。
在参与该项目的所有515名青少年中，对照组和干预组青少年在基线期或随访期的禁欲率或使用避孕套性行为的发生率没有差异。然而，对基线期无性行为经历的青少年亚组（n = 255）进行的分析显示，一年后仍无性行为经历的干预组青少年比例（17%）高于对照组青少年（9%，P<0.05）。此外，在干预刚结束后，在基线期为处女随后开始性行为的人群中，干预组青少年比对照组青少年更有可能使用避孕套（分别为18%和10%，P<0.05）。干预对其他与艾滋病病毒相关的风险行为（未与性伴侣讨论既往艾滋病病毒感染风险暴露情况以及饮酒）、使用避孕套的意愿以及对使用避孕套能力的认知产生了积极影响。
有证据表明，“我的未来我做主”（MFMC）干预措施正在降低15 - 18岁无性行为经历参与者的艾滋病病毒感染风险行为。该干预措施对相关风险行为和认知也产生了积极影响。
