Child cognitive development is often compromised in contexts of poverty and adversity, and these deficits tend to endure and affect the child across the life course. In the conditions of poverty and violence that characterise many low- and middle-income countries (LMIC), the capacity of parents to provide the kind of care that promotes good child development may be severely compromised, especially where caregivers suffer from depression. One avenue of early intervention focuses on the quality of the early mother–infant relationship. The aim of this study was to examine the long-term impact of an early intervention to improve the mother–infant relationship quality on child cognitive outcomes at 13 years of age. We also estimated the current costs to replicate the intervention.

前 1000 天：对母亲来说够了，但对孩子来说不够？早期干预母亲抑郁情绪和儿童认知发展的长期结果：随机对照试验的随访

在贫困和逆境的情况下，儿童的认知发展往往会受到影响，这些缺陷往往会持续存在并影响儿童的整个生命历程。在许多低收入和中等收入国家 (LMIC) 的贫困和暴力条件下，父母提供促进儿童良好发展的护理的能力可能会受到严重影响，尤其是在照顾者患有抑郁症的情况下。早期干预的一种途径侧重于早期母婴关系的质量。本研究的目的是检查早期干预以改善母婴关系质量对 13 岁儿童认知结果的长期影响。我们还估计了复制干预的当前成本。
