To determine the impact on teenage pregnancy of interventions that address the social disadvantage associated with early parenthood and to assess the appropriateness of such interventions for young people in the United Kingdom.
Systematic review, including a statistical meta-analysis of controlled trials on interventions for early parenthood and a thematic synthesis of qualitative studies that investigated the views on early parenthood of young people living in the UK.
12 electronic bibliographic databases, five key journals, reference lists of relevant studies, study authors, and experts in the field. Review methods Two independent reviewers assessed the methodological quality of studies and abstracted data.
Ten controlled trials and five qualitative studies were included. Controlled trials evaluated either early childhood interventions or youth development programmes. The overall pooled effect size showed that teenage pregnancy rates were 39% lower among individuals receiving an intervention than in those receiving standard practice or no intervention (relative risk 0.61; 95% confidence interval 0.48 to 0.77). Three main themes associated with early parenthood emerged from the qualitative studies: dislike of school; poor material circumstances and unhappy childhood; and low expectations for the future. Comparison of these factors related to teenage pregnancy with the content of the programmes used in the controlled trials indicated that both early childhood interventions and youth development programmes are appropriate strategies for reducing unintended teenage pregnancies. The programmes aim to promote engagement with school through learning support, ameliorate unhappy childhood through guidance and social support, and raise aspirations through career development and work experience. However, none of these approaches directly tackles all the societal, community, and family level factors that influence young people's routes to early parenthood.
A small but reliable evidence base supports the effectiveness and appropriateness of early childhood interventions and youth development programmes for reducing unintended teenage pregnancy. Combining the findings from both controlled trials and qualitative studies provides a strong evidence base for informing effective public policy.
确定应对与早育相关的社会不利因素的干预措施对青少年怀孕的影响,并评估此类干预措施对英国年轻人的适用性。
系统评价,包括对早育干预措施的对照试验进行统计荟萃分析,以及对调查英国年轻人对早育看法的定性研究进行主题综合分析。
12个电子书目数据库、5种主要期刊、相关研究的参考文献列表、研究作者以及该领域的专家。综述方法:两名独立评审员评估研究的方法学质量并提取数据。
纳入了10项对照试验和5项定性研究。对照试验评估了幼儿期干预措施或青年发展项目。总体合并效应量显示,接受干预的个体的青少年怀孕率比接受标准做法或未接受干预的个体低39%(相对风险0.61;95%置信区间0.48至0.77)。定性研究中出现了与早育相关的三个主要主题:不喜欢上学;物质条件差和童年不幸福;以及对未来期望低。将这些与青少年怀孕相关的因素与对照试验中使用的项目内容进行比较表明,幼儿期干预措施和青年发展项目都是减少意外青少年怀孕的合适策略。这些项目旨在通过学习支持促进与学校的互动,通过指导和社会支持改善不幸福的童年,并通过职业发展和工作经验提高期望。然而,这些方法都没有直接解决影响年轻人早育途径的所有社会、社区和家庭层面的因素。
少量但可靠的证据支持幼儿期干预措施和青年发展项目在减少意外青少年怀孕方面的有效性和适用性。将对照试验和定性研究的结果结合起来为制定有效的公共政策提供了有力的证据基础。
