Table 2.

Per capita unadjusted mean medical expenditures among adults aged 18–64 years, differentiated by diabetes treatment mode and major depressive disorder (MDD) status.

Diabetes treatment mode	MDD Status	n	Expenditures (2008 $)

			Outpatient	Inpatient	Prescription drugs	Total
ITDM (n = 101,050)	MDD w/Med	4441	14,512	15,384	9122	39,018
	MDD w/out Med	595	13,431	11,162	5683	30,276
	No MDD	96,014	7986	5338	5069	18,393
NITDM (n = 299,445)	MDD w/Med	9453	10,877	7556	6313	24,747
	MDD w/out Med	1428	9229	6407	3321	18,957
	No MDD	288,564	5003	2625	2656	10,284

ITDM, insulin-treated diabetes mellitus; NITDM, non-insulin-treated diabetes mellitus.

MDD w/Med: persons with MDD treated with antidepressant medication; MDD w/out Med: persons with MDD not treated with antidepressant medication.

Difference in mean expenditures between MDD w/Med and no MDD, between MDD w/out Med and no MDD were all statistically different (p < 0.01, one tailed).

Difference in mean expenditures for outpatient, prescription drugs and total expenditures between MDD w/Med and MDD w/out Med (except for inpatient expenses; not significant at 5%) were statistically different (p < 0.01).

Difference in mean expenditures between ITDM and NITDM means were statistically different for all corresponding categories (p < 0.01).
