Table 4. Associations between BMI at conscription and attempted and completed suicide 1981–2008^a; crude and adjusted hazard ratios per one standard deviation increase in BMI.

	Attempted suicide		Completed suicide
Total n (cases)	44 440 (821)		44 440 (408)
	HR	95% CI	HR	95% CI
Crude	0.89	0.83–0.96	0.94	0.85–1.04
Adjusted for:
All earlier variablesb	0.91	0.84–0.97	0.94	0.85–1.04
Psychiatric diagnosis 1973–80	0.92	0.85–0.98	0.96	0.87–1.06
SEP 1980	0.89	0.83–0.96	0.94	0.85–1.04
Unmarried/living alone 1980	0.90	0.84–0.96	0.95	0.86–1.04
All variables in adulthood	0.91	0.85–0.98	0.96	0.87–1.06
All variablesc	0.93	0.86–1.00	0.96	0.87–1.06

Abbreviations: BMI, Body Mass Index; CI, Confidence Interval; HR, Hazard Ratio; N, Number; SEP, Socio-Economic Position.

^aMen who died before 1981 or have missing data on any variable recorded in adulthood are excluded; thus, estimates are slightly different from the analyses presented in table 3.

^bAdjusted for childhood SEP, crowded housing, height, emotional control, risky use of alcohol, smoking, depressed mood, and psychiatric diagnosis at conscription.

^cAdjusted for all factors in childhood, at conscription and in adulthood.
