Prospective study of depressive symptoms and risk of stroke among japanese

We sought to examine the relationship between depressive symptoms and the incidence of stroke among Japanese men and women. A 10.3-year prospective study on the relationship between depressive symptoms and the incidence of stroke was conducted with 901 men and women aged 40 to 78 years in a rural Japanese community. Depressive symptoms were measured at baseline with the use of the Zung Self-Rating Depression Scale (SDS). The incidence of stroke was ascertained under systematic surveillance. During the 10-year follow-up, 69 strokes (39 ischemic strokes, 10 intracerebral hemorrhages, 10 subarachnoid hemorrhages, and 10 unclassified strokes) occurred. Age- and sex-adjusted prevalence of mild depression (SDS scores >/=40) at baseline was 25% among subjects with incident stroke and 12% among subjects without stroke (P
