Evidence about long-term effects of preventive health services for youth with complex needs is lacking. Prime Time, a youth development intervention, aims to reduce pregnancy risk among vulnerable adolescent females seeking clinic services.
In a randomized trial, 253 sexually active females aged 13-17 who were at high risk for pregnancy were assigned to the Prime Time intervention or usual clinic services. The 18-month intervention, initiated in 2007-2008, comprised regular meetings with case managers and participation in youth leadership groups. Trial participants completed surveys at baseline and 30 months. Regression analyses were used to evaluate differences between groups in sexual and psychosocial outcomes at follow-up.
At 30 months, the intervention group reported more months of consistent condom use (adjusted means, 1.8 vs. 1.1) and dual contraceptive use (0.9 vs. 0.3) in the past seven months than did controls. The intervention was most effective in promoting consistent use among participants with relatively high levels of connectedness to family or school. Fifteen percent of intervention participants, but only 6% of controls, reported having abstained from sex in the past six months (adjusted odds ratio, 2.9). Moreover, among high school graduates, those in the intervention group were more likely than those in the control group to have enrolled in college or technical school (72% vs. 37%; odds ratio, 4.5).
Health services grounded in a youth development framework can lead to reductions in sexual risk among vulnerable youth that are evident one year following conclusion of services.
针对有复杂需求的青年进行预防保健服务的长期效果的证据尚缺乏。黄金时间是一项青年发展干预措施,旨在降低寻求诊所服务的弱势青春期少女的怀孕风险。
在一项随机试验中,253 名有性行为且年龄在 13-17 岁之间、怀孕风险高的女性被分配到黄金时间干预组或常规诊所服务组。该 18 个月的干预措施于 2007-2008 年开始,包括与个案经理定期会面和参加青年领导小组。试验参与者在基线和 30 个月时完成了调查。回归分析用于评估随访时两组在性和心理社会结果方面的差异。
在 30 个月时,干预组报告过去七个月中有更多的月份持续使用避孕套(调整后的平均值,1.8 比 1.1)和双重避孕措施(0.9 比 0.3),比对照组多。该干预措施在促进与家庭或学校联系程度较高的参与者持续使用方面最有效。15%的干预组参与者,而只有 6%的对照组参与者,报告在过去六个月中禁欲(调整后的优势比,2.9)。此外,在高中毕业生中,干预组比对照组更有可能进入大学或技术学校(72%比 37%;优势比,4.5)。
以青年发展框架为基础的卫生服务可以减少弱势青年的性风险,这种效果在服务结束一年后仍然明显。
