Depression Increased Stroke Risk抑郁增加中风风险

A cohort study of US adults over age 50 found that depressive symptoms were associated with increased stroke risk even if depressive symptoms remitted over a 2‐year period. Study participants (n=16 178, stroke free and noninstitutionalized at baseline) were interviewed biennially from 1998 to 2010. Adjusted marginal structural Cox proportional hazards were used and stratified by age, race or ethnicity, and sex. Stroke hazard was elevated among participants with stable high or remitted depressive symptoms compared with participants with stable low/no depressive symptoms. Stable high depressive symptom predicted stroke among all subgroups. Remitted depressive symptoms predicted increased stroke hazard among women and non‐Hispanic white participants and was marginally associated among Hispanics. The link between depression and stroke is well established. Biological mechanisms driving the depression-stroke link could be long term or short term.
