Table 2. Logistic regression analyses using caseness of anxiety, depression, insomnia, excessive sleepiness and chronic fatigue as dependent variables, and night work status (no night work experience, current night work, previous night work) as independent variables.

	Crude					Adjusted*
	Anxiety	Depression	Insomnia	Excessive sleepiness	Chronic fatigue	Anxiety	Depression	Insomnia	Excessive sleepiness	Chronic fatigue
No night work experience	1.00	1.00	1.00	1.00	1.00	1.00	1.00	1.00	1.00	1.00
Current night work	1.04 (.73–1.49)	1.46 (.82–2.59)	1.38 (1.04–1.83)	1.21 (.87–1.68)	1.69 (1.02–2.81)	1.18 (.81–1.74)	1.35 (.75–2.42)	1.48 (1.10–1.99)	1.27 (.90–1.80)	1.78 (1.02–3.11)
Previous night work	1.13 (.76–1.68)	1.78 (.96–3.29)	1.33 (.97–1.83)	.99 (.69–1.43)	1.73 (1.00–3.00)	1.27 (.82–1.94)	1.53 (.81–2.87)	1.45 (1.04–2.02)	1.12 (.76–1.65)	1.69 (.93–3.09)

The independent variables were inserted simultaneously, and no night work experience was used as the reference category. Results are reported as odds-ratios, and 95% confidence intervals are shown in parentheses. Underlined values are statistically significant.

^*Adjusted analyses were adjusted for age, gender, and years of work experience, marital status and children living at home.
