The mental health status of refugees and asylum seekers attending a refugee health clinic including comparisons with a matched sample of Australian-born residents

Table 5 Risk Ratio estimates comparing mental illness in the study refugee sample with matched Australian-born group

	K10 abnormal (≥ 20) % (n)	K10 normal (<20) % (n)	Conditional RR^a (95% CI)
Refugee clinic sample	50.7 (68)	49.3 (66)	3.16 (2.30 to 4.34)
Australian-born matched sample	16.1 (86)	83.9 (449)	3.16 (2.30 to 4.34)
	PTSD – yes % (n)	PTSD – no % (n)
PTSD – lifetime^b
Refugee clinic sample	30.6 (41)	66.4 (89)	2.25 (1.53 to 3.29)
Australian-born matched sample	13.8 (74)	86.2 (461)	2.25 (1.53 to 3.29)
PTSD – month^b
Refugee clinic sample	22.4 (30)	74.6 (100)	4.44 (2.64 to 7.48)
Australian-born matched sample	5.0 (27)	95.0 (508)	4.44 (2.64 to 7.48)
	Abnormal K10 and/or PTSD % (n)	Normal K10 and no PTSD % (n)
K10 and/or PTSD – lifetime^b
Refugee clinic sample	56.7 (76)	43.3 (58)	2.84 (2.09 to 3.87)
Australian-born matched sample	26.4 (141)	73.6 (394)	2.84 (2.09 to 3.87)
K10 and/or PTSD – month^b
Refugee clinic sample	51.5 (69)	48.5 (65)	2.15 (1.62 to 2.85)
Australian-born matched sample	18.1 (97)	81.9 (438)	2.15 (1.62 to 2.85)

Note. There were 134 refugees with matched comparisons included in this analysis. All refugees completed the K10 but 131 completed the PTSD-8
^aRisk ratio (RR) is estimated from the conditional Poisson regression model, where the ‘conditional’ refers to stratum created for each matched set
^bPTSD screened in the refugee sample using the PTSD-8 and classified in the Australian-born matched sample using ICD–10 criteria
