Abstract
ABSTRACTBackground:US suicide rates among older women have substantially increased over the past decade. We examined potential differences in sociodemographic and risk/precipitating factors among older female suicide decedents who died by drug overdose versus firearms, hanging/suffocation, and other means, and postmortem toxicology results by suicide means. METHODS: Data are from the 2005 to 2015 US National Violent Death Reporting System (N = 12,401 female decedents aged 50 years and over). We used three logistic regression models, with overdose versus firearms, overdose versus hanging/suffocation, and overdose versus "other" means as the dependent variables, to examine associations between suicide means and sociodemographic and risk/precipitating factors. χ2 tests were used to examine positive toxicology of prescription and illicit drugs by suicide means. RESULTS: Compared to firearm users, overdose users were younger and had higher odds of having had previous suicide attempts/intent disclosures, mental disorders (e.g. depression/dysthymia: AOR = 1.18, 95% CI = 1.05-1.34), and substance abuse other than alcohol, but lower odds of having had relationship problems and any crisis. Compared to hanging/suffocation, overdose declined (AOR = 0.95, 95% CI = 0.93-0.97) during the study period and was less prevalent among Hispanic and Asian women and those with job/finance/housing problems. Toxicology reports showed that 47%, 43%, and 45% of overdose users were antidepressant, opiate, and benzodiazepine positive, respectively. Firearm users had the lowest rates of positive toxicology results for these drugs. CONCLUSIONS: Suicide prevention should include limiting access to large quantities of prescription medications and firearms for those at risk of suicide. More effective mental health/substance abuse treatment and chronic illness management support are also needed.
