Healio (8/1, Laboy) reported a study found that “sleep/wake rhythm disruptions were associated with greater suicidal ideation severity among older adults with depression.” Thirty study participants with a mean age of 62 and a history of depression “wore an actigraph device on their wrist to track sleep/wake measures, including duration, fragmentation, interdaily stability and relative amplitude.” Researchers found that “when adjusted for depression severity, both interdaily stability and relative amplitude remained significantly associated with suicidal ideation despite being attenuated by 36% to 40%. The sleep duration-suicide ideation association was attenuated by 83% and lost its statistical significance.” Researchers concluded, “These data suggest that both insufficient sleep duration and rhythm disturbances are targets for suicide prevention, although these factors may act through different pathways.” The study was published in the Journal of Clinical Psychiatry.
