Relationship between childhood socioeconomic position and adverse childhood experiences (ACEs): a systematic review

'Adverse childhood experiences' (ACEs) are associated with increased risk of negative outcomes in later life: ACEs have consequently become a policy priority in many countries. Despite ACEs being highly socially patterned, there has been very little discussion in the political discourse regarding the role of childhood socioeconomic position (SEP) in understanding and addressing them. The aim here was to undertake a systematic review of the literature on the relationship between childhood SEP and ACEs.

MEDLINE, PsycINFO, ProQuest and Cochrane Library databases were searched. Inclusion criteria were: (1) measurement of SEP in childhood; (2) measurement of multiple ACEs; (3) ACEs were the outcome; and (4) statistical quantification of the relationship between childhood SEP and ACEs. Search terms included ACEs, SEP and synonyms; a second search additionally included 'maltreatment'. Overall study quality/risk of bias was calculated using a modified version of the Hamilton Tool.
