Poor Sleep and Decision-Making Disturbance Are Associated With Suicidal Ideation in Pre-natal Depression

Insomnia, poor sleep quality and perinatal suicidal risk: A systematic review and meta-analysis

Suicidal risk in mothers is a public health priority. Risk factors include biological, psychological and psychosocial factors. Among the biological factors, the role of sleep disturbances as potential contributors to increased suicidal risk during the peripartum period is becoming apparent. To explore this further, we conducted a systematic review following the PRISMA criteria. Currently, 10 studies have examined the role of insomnia and poor sleep quality in suicidal risk during the peripartum period and have involved 807,760 women. The data showed that disturbed sleep and poor sleep quality increase the risk of suicidal ideation in both pregnant women with and without perinatal depression. The results of the meta-analysis indicated that insomnia and poor sleep quality increase the odds of suicidal risk in pregnant women by more than threefold (OR = 3.47; 95% CI: 2.63-4.57). Specifically, the odds ratio (OR) for poor sleep quality was 3.72 (95% CI: 2.58-5.34; p < 0.001), and for insomnia symptoms, after taking into account perinatal depression, was 4.76 (95% CI: 1.83-12.34; p < 0.001). These findings emphasise the importance of assessing and addressing sleep disturbances during the peripartum period to mitigate their adverse effects on peripartum psychopathology and suicidal risk.

Relationships among insomnia, executive function, and suicidal ideation in depressed outpatients: A mediation analysis

Insomnia is a risk factor for suicide, and both are associated with cognitive problems. However, prior research has not examined insomnia, cognition, and suicidal ideation within one sample. We describe cross-sectional associations among insomnia, psychomotor speed, set shifting, and suicidal ideation in 85 depressed adults. Greater insomnia was associated with slower psychomotor speed, while slower psychomotor speed was associated with a greater level (i.e., elaboration of suicide planning) and intensity of suicidal ideation in the past week. Slower set shifting was associated with a greater level and intensity of suicidal ideation in the past week. Mediation analysis indicated that psychomotor speed and set shifting both had a significant total effect on the intensity of suicidal ideation in the past week; set shifting also had a significant total effect on the sum of intensity and suicidal ideation level in the past week. The level of insomnia explained only small percentages of the total effect of either psychomotor speed or set shifting on the intensity of suicidal ideation and the sum of intensity and suicidal ideation level. The findings in this sample demonstrate significant associations of slower psychomotor speed and set shifting with suicidal ideation, with negligible contribution from insomnia.

Maternal Suicide Ideation and Behaviour During Pregnancy and the First Postpartum Year: A Systematic Review of Psychological and Psychosocial Risk Factors

Suicide is a leading cause of maternal death during pregnancy and up to a year after birth (perinatal period). Many psychological and psychosocial risk factors for maternal suicidal ideation and behaviour have been investigated. Despite this, there have been no attempts to systematically search the literature on these risk factors. Additionally, few studies have described how the risk factors for suicidal ideation, attempted suicides and suicide deaths differ, which is essential for the development of tools to detect and target suicidal ideation and behaviour. Seven databases were searched up to June 2021 for studies that investigated the association between suicidal ideation and/or suicidal behaviour and psychological/psychosocial risk factors in pregnant and postpartum women. The search identified 17,338 records, of which 59 were included. These 59 studies sampled a total of 49,929 participants and investigated 32 different risk factors. Associations between abuse, experienced recently or during childhood, and maternal suicide ideation, attempted suicide and death were consistently reported. Social support was found to be less associated with suicide ideation but more so with suicide attempts. Identifying women who have experienced domestic violence or childhood abuse and ensuring all women have adequate emotional and practical support during the perinatal period may help to reduce the likelihood of suicidal behaviour.

Suicide and Maternal Mortality

PURPOSE OF REVIEW

Suicide is a leading cause of death in the perinatal period (pregnancy and 1 year postpartum). We review recent findings on prevalence, risk factors, outcomes, and prevention and intervention for suicide during pregnancy and the first year postpartum.

RECENT FINDINGS

Standardization of definitions and ascertainment of maternal deaths have improved identification of perinatal deaths by suicide and risk factors for perinatal suicide. Reports of a protective effect of pregnancy and postpartum on suicide risk may be inflated. Clinicians must be vigilant for risk of suicide among their perinatal patients, especially those with mental health diagnoses or prior suicide attempts. Pregnancy and the year postpartum are a time of increased access to healthcare for many, offering many opportunities to identify and intervene for suicide risk. Universal screening for suicide as part of assessment of depression and anxiety along with improved access to mental health treatments can reduce risk of perinatal suicide.

Suicidal ideation and behavior among perinatal women and their association with sleep disturbances, medical conditions, and known risk factors

OBJECTIVE

Suicide is considered one of the leading causes of maternal mortality, especially among women with postpartum depression. In the current systematic review, we conducted a qualitative data synthesis of recent studies exploring novel risk factors including sleep disturbances and medical conditions, alongside known and significant risk factors for perinatal suicidality.

EVIDENCE ACQUISITION

We conducted a systematic search of the literature according to PRISMA guidelines on PubMed, PsycNET, and Scopus databases. Search terms were "pregnancy" "OR" "postpartum" "OR" "peripartum" "OR" "perinatal" "OR" "postnatal" combined with the Boolean "AND" operator with "suicide" "OR" "suicidality" "OR" "suicidal ideation" "OR" "suicidal behavior."

EVIDENCE SYNTHESIS

The initial search yielded 1,458 records, of which 51 research reports that met inclusion criteria were analyzed. These 51 studies sampled a total of 45,942 participants. Clinically, sleep disturbance, psychopathology, and social support have been identified as dominant risk factors for suicidal behavior among pregnant and postpartum women, as well as medical conditions and aversive life events.

CONCLUSION

Monitoring sleep disturbance, depression, and perceived social support is critical given that they are significant risk factors for suicide among perinatal women. Early identification of perinatal women who may be at risk of suicide, although not depressed, is crucial.

LIMITATIONS

The use of tools designed to identify depression to identify suicidal risk, fail to identify women who are at risk but who do not suffer from depression. Other methodological limitations are the lack of longitudinal studies and the complexity of examining suicidal behavior in sample studies.
