A pilot scheme was introduced in Manchester to provide additional social support to pregnant women at above average risk of giving birth to a low-birthweight baby. The help of lay workers, known as family workers, was made available to eligible women. The effect on infant birthweight of offering the help of a family worker was assessed by a randomized controlled trial. No significant differences were observed between the experimental and control group, but on a number of grounds the interpretation of this finding is not straightforward, and further research is recommended.
在曼彻斯特推行了一项试点计划，为分娩低体重婴儿风险高于平均水平的孕妇提供额外的社会支持。向符合条件的妇女提供了非专业工作人员（即家庭工作人员）的帮助。通过一项随机对照试验评估了提供家庭工作人员帮助对婴儿出生体重的影响。实验组和对照组之间未观察到显著差异，但基于若干理由，这一结果的解释并不简单，因此建议进行进一步研究。
