A strong and consistent relationship has been observed between relative poverty and poor child health and wellbeing even among rich nations. This review set out to examine evidence that additional monies provided to poor or disadvantaged families may benefit children by reducing relative poverty and thereby improving children's health, well-being and educational attainment.
To assess the effectiveness of direct provision of additional monies to socially or economically disadvantaged families in improving children's health, well-being and educational attainment
In total 10 electronic databases were searched including the Cochrane library searched 2006 (Issue 1), Medline searched 1966 to May 2006 , Econlit searched 1969 to June 2006 and PsycINFO searched 1872 to June 2006, together with 3 libraries of working papers (MDRC, SSRN, SRDC). The general search strategy was [terms for income and financial benefits] and [paediatric terms] and [RCT filter]
Studies selected provided money to relatively poor families (which included a child under the age of 18 or a pregnant woman), were randomised or quasi-randomised, measured outcomes related to child health or wellbeing and were conducted in a high income country.
Titles and abstracts identified in the search were independently assessed for eligibility by two reviewers. Data were extracted and entered into RevMan, synthesised and presented in both written and graphical form (forest plots).
Nine trials including more than 25,000 participants were included in this review. No effect was observed on child health, measures of child mental health or emotional state. Non-significant effects favouring the intervention group were seen for child cognitive development and educational achievement, and a non-significant effect favouring controls in rates of teenage pregnancy.
AUTHORS' CONCLUSIONS: The review set out to examine the potential of financial support to poor families to improve circumstances for children. However, on the basis of current evidence we can not state unequivocally whether financial benefits delivered as an intervention are effective at improving child health or wellbeing in the short term. Our conclusions are limited by the fact that most of the studies had small effects on total household income and that while no conditions were attached to how money was spent, all studies included strict conditions for receipt of payments. We note particular concerns by some authors that sanctions and conditions (such as working hours) placed on families may increase family stress.
即使在富裕国家,也已观察到相对贫困与儿童健康及幸福之间存在着紧密且一致的关系。本综述旨在研究证据,即向贫困或处境不利家庭提供额外资金,是否可能通过减少相对贫困从而改善儿童健康、幸福和教育成就,使儿童受益。
评估直接向社会或经济处境不利家庭提供额外资金,对改善儿童健康、幸福和教育成就的有效性。
共检索了10个电子数据库,包括2006年第1期的考克兰图书馆、1966年至2006年5月的医学期刊数据库、1969年至2006年6月的经济文献数据库以及1872年至2006年6月的心理学文摘数据库,还检索了3个工作论文库(MDRC、SSRN、SRDC)。一般检索策略为[收入和经济福利相关术语]、[儿科术语]和[随机对照试验过滤器]。
入选研究向相对贫困家庭(包括18岁以下儿童或孕妇)提供资金,采用随机或准随机分组,测量与儿童健康或幸福相关的结果,且在高收入国家进行。
两名评审员独立评估检索到的标题和摘要的入选资格。提取数据并录入RevMan,进行综合分析,并以书面和图表形式(森林图)呈现。
本综述纳入了9项试验,涉及超过25000名参与者。未观察到对儿童健康、儿童心理健康或情绪状态测量指标有影响。在儿童认知发展和教育成就方面,干预组有非显著的有利影响,而在青少年怀孕率方面,对照组有非显著的有利影响。
本综述旨在研究对贫困家庭的经济支持改善儿童状况的潜力。然而,根据现有证据,我们无法明确说明作为一种干预措施提供的经济福利在短期内是否能有效改善儿童健康或幸福。我们的结论受到以下事实限制:大多数研究对家庭总收入的影响较小,而且虽然资金使用方式没有附加条件,但所有研究都对资金接收设定了严格条件。我们注意到一些作者特别担心对家庭施加的制裁和条件(如工作时间)可能会增加家庭压力。
