“…Prolonged, excessive stress or depression are linked with thinking about suicide and attempted suicide (GoldmanMellor et al 2014); and most suicide attempts are by those who have previously thought of suicide (Bronisch and Wittchen 1994). For example, a 14-year follow-up study reported that stress and suicidal ideation were associated with action of suicidal thoughts (Fujino et al 2005). Short sleep duration may affect both psychological and physiological health conditions, with negative effects on judgment, fatigue, stress, and impulse control.…”

Prolonged sedentary time and sleep deprivation are associated with mental health problems such as depression and stress symptoms. Moreover, mental illness is linked with suicidal thoughts and suicide attempts. However, it is not clear whether sedentary time and sleep duration are associated with stress symptoms and suicidal thoughts independent of physical activity. Thus, our study aimed to identify if sedentary time and sleep duration were associated with both stress symptoms and suicidal thoughts. The participants in present cross-sectional study were 4,674 general Korean adults (1,938 male; 2,736 female), aged ≥ 20 years. Prolonged sedentary time (≥ 420 min/day) was significantly associated with the increased risk of stress symptoms (OR, 1.30; 95% CI, 1.04-1.62) compared with sedentary time of < 240 min/day. The OR for stress symptoms was significant for individuals who had ≤ 5 h/day of sleep time (OR, 1.88; 95% CI, 1.48-2.38) compared with sleep duration of ≥ 7 h/day. Moreover, prolonged sedentary time (OR, 1.55; 95% CI, 1.01-2.42 in ≥ 420 min/day vs. < 240 min/day) and short sleep duration (OR, 1.75; 95% CI, 1.17-2.62 in ≤ 5 h/day vs. ≥ 7 h/day) were significantly associated with an increased risk for suicidal thoughts after adjusting for confounding factors including physical activity. Thus, prolonged sedentary time and sleep deprivation are independently associated with both the risk of stress symptoms and suicidal thoughts. From a public health perspective, reducing sedentary time and improvement of sleep deprivation may serve as an effective strategy for preventing mental illness.

“…6,7 However, in recent years there has been growing evidence that sleep problems are risk factors for self-harm and suicidal behaviour and that this relationship is independent of psychiatric disorder. [8][9][10][11][12] Despite the accumulation of evidence confirming a relationship between sleep problems and self-harm in adolescents, the utility of the findings has been circumscribed because the measures of sleep have tended to be brief. As a consequence, it is not clear whether specific characteristics of sleep disturbance are more strongly associated with risk of self-harm than others.…”

Sleep problems and self-harm in adolescence

ResultsAdolescents with sleep problems were significantly more likely to report self-harm than those without sleep problems. Insomnia, short sleep duration, long sleep onset latency, wake after sleep on set as well as large differences between weekdays versus weekends, yielded higher odds of self-harm consistent with a dose-response relationship. Depressive symptoms accounted for some, but not all, of this association. ConclusionsThe findings highlight a strong relationship between sleep problems and self-harm. Interventions to reduce adolescent self-harm ought to incorporate sleep problems as a treatment target.

“…This link has been reported in both clinical (Ağargün and Cartwright, 2003;Bernert et al, 2005;Sabo et al, 1991) and nonclinical population-based samples (Fujino et al, 2005;Goodwin and Marusic, 2008;Turvey et al, 2002) regarding suicidal ideation, suicide attempt, and death by suicide.…”

“…Cross-sectionally, insomnia has repeatedly been linked to greater levels of suicidal ideation (Ağargün et al, 1997a;Barraclough and Pallis, 1975) even after controlling for depressive symptoms (Bernert et al, 2005(Bernert et al, , 2009Chellappa and Araújo, 2007), and suicidal behavior (Goldstein et al, 2008;Sjöström et al, 2007). Longitudinal studies (though few) provide even more compelling evidence, indicating that insomnia emerges as a significant predictor of later suicidal ideation (McCall et al, 2010) and death by suicide (Fawcett et al, 1990;Fujino et al, 2005;Turvey et al, 2002).…”

The Denver staff continues to collaborate with the Florida State University site and seek guidance from its senior advisors, the Military External Advisory Board, and the Independent Scientific Peer Review Program. The MSRC is on track with its goals and is financially mindful in leveraging funds and reviewing its infrastructure to increase the funds available to support additional research. The MSRC also submitted a grant application to extend through years 6-10, establishing new research priorities and extending its scope. SUBJECT TERMS• Funding research projects Introduction:The Military Suicide Research Consortium's ultimate goal is suicide prevention in the military, through research, including on primary, secondary, and tertiary interventions, as well as through information management/scientific communications (cataloguing and disseminating knowledge on military suicide). Specifically, suicidal personnel compromise force readiness, place a strain on the healthcare resources of the military, impact unit morale, and take a large emotional toll on the involved friends, family, and commanders. There is significant stigma associated with being suicidal, which limits the extent to which at-risk individuals are willing to seek help. Moreover, decision-makers need a go-to resource for accurate, efficient, and fast answers regarding suicidal behavior as policies and programs are devel...
