Table 4. 3-year incidence of (comorbid) common mental disorders.

Incident any mood disorder (n at risk = 4,098) Incident any anxiety disorder (n at risk = 4,113) Incident any substance use disorder (n at risk = 4,326)
% OR (95% CI) % OR (95% CI) % OR (95% CI)
NONE 4.7 1 4.2 1 3.3 1
PHYonly 4.5 1.14 (0.72,1.80)* 5.1 1.40 (0.94,2.07) 2.4 1.14 (0.61,2.12)
MUSonly 8.7 1.89 (0.97,3.71) 5.7 1.29 (0.54,3.10) 4.0 1.76 (0.56,5.51)
MUS+PHY 10.3 2.92 (1.27,6.74)* 6.5 1.60 (0.72,3.54) 2.2 1.91 (0.54,6.77)

The analyses were adjusted for sex, age, partner status, employment situation and level of education.

NONE: No explained physical symptoms, no MUS

PHYonly: explained physical symptoms, no MUS

MUSonly: MUS, no explained physical symptoms

MUS+PHY: both MUS and explained physical symptoms

Percentages: weighted data

OR: odds ratio

95% CI: 95% confidence interval

The number at risk varies per category, because only first incidence cases were used.

* When PHYonly, MUSonly and MUS+PHY were respectively used as the reference group, the only significant difference was found between PHYonly and MUS+PHY for any incident mood disorder.
