Marital status, sex, and suicide: new longitudinal findings and Durkheim’s marital status propositions

Abstract

The purpose of the paper was to use new longitudinal data to investigate the impact of marital status on suicide, and test Durkheim’s marital status propositions. Previous research found marital status was associated with suicide, but some studies neglected sex, most of the research was cross-sectional, and divorce and separated statuses were often combined. Data were obtained from the latest release of the U.S. National Longitudinal Mortality Study (NLMS), consisting of the largest U.S. sample of suicide victims, 2,013 out of 1.5 million persons. Proportional hazards and logistic regression models were fitted to the NLMS data based on follow-up from 1990 to 2011. Results showed that when combined, the divorced and separated were over 88% more likely to suicide than the married (ARR = 1.886, CI = 1.649, 2.156). When split, the divorced had suicide risk that was over 97% higher than that of the married (ARR = 1.973, CI = 1.711, 2.274). Separated individuals experienced suicide risk that was nearly 52% greater than that of the married (ARR = 1.515, CI = 1.130, 2.037). The Mountain and southern census divisions had higher suicide risks than New England. Discussion focused mainly on Durkheim’s theory of suicide.
