What are the trends in suicidal ideation and intentional self-harm in a large national cohort of commercially insured childbearing individuals?
In this serial cross-sectional analysis of 595 237 childbearing individuals 1 year before and after giving birth, suicidal ideation and intentional self-harm increased significantly between 2006 and 2017. Non-Hispanic Black individuals, those with low-income, and younger individuals as well as those with comorbid anxiety, depression, or other serious mental illness had larger escalations.
Clinical and policy interventions for addressing this health crisis should be tailored to meet the unique needs of childbearing individuals in the year before and following birth, particularly among high-risk groups.
Suicide deaths are a leading cause of maternal mortality in the US, yet the prevalence and trends in suicidality (suicidal ideation and/or intentional self-harm) among childbearing individuals remain poorly described.
To characterize trends in suicidality among childbearing individuals.
Design, Setting, and Participants
This serial cross-sectional study analyzed data from a medical claims database for a large commercially insured population in the US from January 2006 to December 2017. There were 2714 diagnoses of suicidality 1 year before or after 698 239 deliveries among 595 237 individuals aged 15 to 44 years who were continuously enrolled in a single commercial health insurance plan. Data were analyzed from October 2019 to September 2020.
Main Outcomes and Measures
The primary outcome was diagnosis of suicidality in childbearing individuals 1 year before or after birth based on the identification of relevant International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and ICD-10-CM diagnosis codes during at least 1 inpatient or 2 outpatient visits.
Of 595 237 included childbearing individuals, the mean (SD) age at delivery was 31.9 (6.4) years. A total of 40 568 individuals (6.8%) were Asian, 52 613 (8.6%) were Black, 73 172 (12.1%) were Hispanic, 369 501 (63.1%) were White, and 59 383 (9.5%) had unknown or missing race/ethnicity data. A total of 2683 individuals were diagnosed with suicidality 1 year before or after giving birth for a total of 2714 diagnoses. The prevalence of suicidal ideation increased from 0.1% per 100 individuals in 2006 to 0.5% per 100 individuals in 2017 (difference, 0.4%; SE, 0.03; P < .001). Intentional self-harm prevalence increased from 0.1% per 100 individuals in 2006 to 0.2% per 100 individuals in 2017 (difference, 0.1%; SE, 0.02; P < .001). Suicidality prevalence increased from 0.2% per 100 individuals in 2006 to 0.6% per 100 individuals in 2017 (difference, 0.4%; SE, 0.04; P < .001). Diagnoses of suicidality with comorbid depression or anxiety increased from 1.2% per 100 individuals in 2006 to 2.6% per 100 individuals in 2017 (difference, 1.4%; SE, 0.2; P < .001). Diagnoses of suicidality with comorbid bipolar or psychotic disorders increased from 6.9% per 100 individuals in 2006 to 16.9% per 100 individuals in 2017 (difference, 10.1%; SE, 0.2; P < .001). Non-Hispanic Black individuals, individuals with lower income, and younger individuals experienced larger increases in suicidality over the study period.
Conclusions and Relevance
In this cross-sectional study of US childbearing individuals, the prevalence of suicidal ideation and intentional self-harm occurring in the year preceding or following birth increased substantially over a 12-year period. Policy makers, health plans, and clinicians should ensure access to universal suicidality screening and appropriate treatment for pregnant and postpartum individuals and seek health system and policy avenues to mitigate this growing public health crisis, particularly for high-risk groups.
