The "long arm" of childhood health: linking childhood disability to late midlife mental health.

A growing body of research underscores the early origins of health in later life; however, relatively little is known about the relationship between childhood physical health and adult mental health. This research explores the relationship between childhood disability and depressive symptoms among a nationally representative sample of late midlife adults (N = 3,572). Using data from Waves 8-10 (2006-2010) of the Health and Retirement Study, a series of ordinary least squares regression models were created to assess the number of depressive symptoms. Childhood disability was significantly associated with higher levels of depressive symptoms; however, late midlife social and health factors accounted for differences between those with and without childhood disability. Late midlife physical health appeared to be a particularly salient mediator. Individuals who experience childhood disability may accumulate more physical impairment over the life course, thus experiencing worse mental health such as greater depressive symptoms in late midlife.
