Burns School of Medicine. Aims: To examine mortality rates and causes of death among a cohort of substance-using mothers and to identify risk factors that predict mortality. Design, setting, participants: This is a prospective study of a cohort of 4,447 substance-using mothers (pregnant or parenting) who were enrolled during 2000 to 2002 in 40 drug abuse treatment programs across California. Methods: All mothers were assessed at baseline using the Addiction Severity Index. Mortality data were obtained from the National Death Index and causes of death were coded using ICD-10. Standardized mortality ratios (SMR) were calculated relative to women in the general population adjusted for age. Proportional hazard (Cox) regression was used to identify risk factors predicting death. Results: By the end of 2010, 194 deaths were confirmed, corresponding to a crude mortality rate of 4.47 per 1000 person-years and SMR of 8.4 (95% CI=7.2-9.6). Drug overdose (28.8%), cardiovascular disease (10%), and alcohol or drug disorders (8.9%) were the leading causes of death. Baseline factors associated with higher mortality included older age, being white (relative to African American or Hispanic), heroin, alcohol, cocaine, or marijuana (relative to methamphetamine) as the primary drug problem, drug injection, and greater severity of employment, medical/health, and psychiatric problems. Conclusions: Substance-using mothers have 8.4 times the mortality than that observed among US women of similar age. Greater severity of employment, medical/health, and psychiatric problems contributed to the elevated mortality. Published 11 August 2011 in Addiction.
