Social stress research concerned with understanding health inequalities among older adults does not always consider the potential for early trauma to influence current psychological and subjective well-being. In this project, the stress process and life course perspectives are applied to better understand whether exposure to trauma early in life continues to influence mental and subjective health in the second part of the life course and whether socio-economic status, current stressors, psychosocial resources and social support mediate or moderate this relationship. The sample consists of adults aged 50 years and older from the 1994/1995 Canadian National Population Health Survey. Exposure to childhood trauma was associated with greater psychological distress, depression and poorer self-rated health in later life, and these relationships were partially mediated by the components of the stress process model. Age and gender did not moderate the relationship between early trauma and health in this sample.
