Association between period of residence in prefabricated temporary housing and deterioration of psychological distress among the subjects with lower psychological distress (K6 score <5) at the baseline (n=116)

	Period of residence in prefabricated temporary housing (years)			P trend
	<3 years	3–4 years	>4 years (still living in prefabricated temporary housing)
Number of subjects	59	43	14
Number of subjects with deterioration*	12	11	7
Crude OR (95% CI)	1.00 (reference)	1.35 (0.53 to 3.38)	3.80 (1.15 to 12.78)	0.049
Age–sex adjusted OR (95% CI)	1.00 (reference)	1.31 (0.51 to 3.33)	4.13 (1.22 to 14.50)	0.046
Multivariate adjusted OR (95% CI)†	1.00 (reference)	1.76 (0.61 to 5.29)	4.87 (1.26 to 20.28)	0.032

*Deterioration was defined as the change from lower (K6 score <5) (2011) to higher psychological distress (K6 score ≥5) (2016).

†Adjustment items were age, sex, K6 score at baseline, subjective economic status (poorest, fair to poorer or missing), social ties (strong ties, weak ties or missing) and self-rated health (good health, bad health or missing).
