The multivariate regression analysis models confirmed the association between poor sleep quality and the presence of some or many financial problems (OR 1.74; 95% CI 1.17–2.57 and OR 6.96; 95% CI 3.32–14.55, respectively) and less physical activity or worse eating habits (OR 1.62; 95% CI 1.13–2.32 and OR 3.7; 95% CI 2.2–6.24, respectively). Again, the association between a change toward mixed behaviour in eating habits and poor sleep quality was confirmed in the adjusted model of multivariate regression analyses. The regression models also confirmed the association between poor sleep quality and the presence of a sense of tension (OR 3.51; 95% CI 2.44–5.03), loneliness (OR 3.07; 95% CI 2.07–4.53) upset (OR 3.01; 95% CI 2.10–4.32), uncertainty (OR 2.71; 95% CI 1.81–4.06) fear (OR 2.42; 95% CI 1.65–3.54) and/ or worry (OR 2.30; 95% CI 1.60–3.32) (Appendix A).
