Suicide mortality rate by work status

Status No. at risk No. of suicides Person-years Unadjusted rate (95% CI) Age-adjusted rate (95% CI) Multivariate-adjusted rate (95% CI)
Separated 2,075 10 72,945 13.7 (7.4, 25.5) 13.6 (7.3, 25.4) 13.1 (6.9, 24.8)
Current 1,153 20 18,841 106.1 (68.5, 164.5) 107.2 (69.2, 166.2) 110.5 (70.8, 172.4)
Rate-ratio* 7.7 (3.6, 16.5) 7.9 (3.7, 16.8) 8.4 (3.8, 18.7)

The suicide mortality rate is expressed per 100,000 person-years. The 95% CI was computed using the Poisson regression model.

*

The rate-ratio is calculated as the mortality rate among currently employed officers divided by the mortality rate among separated officers.

**

Rate is adjusted for age and years of service.
