Abstract
The aims of study were to investigate risk factors associated with attempted and completed suicide. This nested case–control study was conducted using the medical and death data of nearly all pregnant women for the period 2002–2012 in Taiwan. A total of 139 cases of attempted suicide and 95 cases of completed suicide were identified; for each case, 10 controls were randomly selected and matched to the cases according to age and year of delivery. A conditional logistic regression model was used. The mean attempted and completed suicide rates were 9.91 and 6.86 per 100,000 women with live births, respectively. Never having married and postpartum depression also increased the risk of attempted suicide (OR = 2.06; 95% CI = 1.09–3.88 and OR = 2.51; 95% CI = 1.10–5.75, respectively) and completed suicide (OR = 20.27; 95% CI = 8.99–45.73 and OR = 21.72; 95% CI = 8.08–58.37, respectively). Other factors for attempted suicide included being widowed or divorced, and having a caesarean delivery or suicide history. Other factors for completed suicide included lower education level, low infant birth weight, and diagnosis of anxiety or mood disorder. These results suggest that people should appropriately assess potential risk factors and provide assistance for postnatal women to reduce the occurrence of suicide events.

Postpartum depression is a common complication of childbearing[6] and has been identified as a major risk of suicide[7]
The data used in this nested case–control study were collected for the period 2000–2012 from the Health and Welfare Data Science Center (HWDC), Ministry of Health and Welfare, Taiwan, which is linked to the National Birth Registry, National Death Certification Registry, and National Health Insurance Research Database (NHIRD) by national identification numbers
Summary
The aims of study were to investigate risk factors associated with attempted and completed suicide. Other factors for completed suicide included lower education level, low infant birth weight, and diagnosis of anxiety or mood disorder. These results suggest that people should appropriately assess potential risk factors and provide assistance for postnatal women to reduce the occurrence of suicide events. The known risk factors for attempted suicide in perinatal women include younger age, unmarried status, a lower education level, previous suicide attempts, intimate partner violence, alcohol or drug use, and psychiatric disorders such as anxiety and depression[10,12,13,14]. Gold et al.[5] examined 2083 female suicide victims and found that mental health, substance use, and intimate partner conflict were associated with pregnancy-associated suicide
