aThe sample of enlisted soldiers (n = 9650 cases, 153,523 control person-months) is a subset of the total sample (n = 193,617 person-months) from the Army STARRS Historical Administrative Data Study (HADS). Control person-months were assigned a weight of 200 to adjust for under-sampling
-
bLogistic regression models included gender, age at Army entry, current age, race/ethnicity, education, marital status, time in service (≤ 1 year, 2 years, 3–4 years, 5–10 years, >10 years), deployment status (never, currently, or previously deployed), and military occupation. The model also included a dummy predictor variable for calendar month and year to control for secular trends
-
cTotal includes both cases (i.e., soldiers with a suicide attempt) and control person-months
-
dRate per 100,000 person-years, calculated based on n1/n2, where n1 is the unique number of soldiers within each category and n2 is the annual number of person-years, not person-months, in the population (n = 3.08 million)
