The association between depression and diabetes in the perinatal period.

Both depression and diabetes are common in the perinatal period and result in serious consequences for mother and fetus. Although the association between depression and diabetes is well established, few studies have examined the association between these disorders during the perinatal period, when the etiology of depression and diabetes may differ from other periods over the life course. This article reviews the four most relevant epidemiologic papers that examined the association between depression and diabetes in the perinatal period and makes recommendations for future studies about how best to examine the association between these disorders during the perinatal period.
