Table 1.
Number of individuals scored on health related variables at military enrolment (N = 918 888).
Table 2.
If an IQ-test was taken, the Stanine score were present. Five is considered mean IQ, while 9 is the highest IQ. If no IQ test was taken the scores A, B and C were used. The two different IQ measures were merged into 1 combined score.

Estimated state probabilities for the states in Fig 1; (1) Employment, (2) Sick leave, (3) Vocational rehabilitation, (4) Medical rehabilitation, (5) Time limited disability benefits, (6) Disability benefits, (7) Emigrated, and (8) Dead. A is for 806 277 men with average to high IQ. B is for 57 092 men with low IQ. C is for 576 414 men without mental health problems. D is for 33 880 men with mental health problems. E is for 518 852 men without mental problems and average to high IQ. F is for the 8 130 men with mental problems and a low IQ.

Table 5.
Unadjusted hazard rate ratios based on discrete time models (generalized estimation equations–GEE), showing the risk ratios with relation to mental health and IQ at military enrolment.
Men with average IQ and no mental health problems are the reference group in all comparisons. There were 585 061 males with complete data for the current analyses.
