Concerning the overall duration of these hospitalizations, the Poisson regression analysis (adjusted for age, sex, and SES) showed that only depression was positively associated with the duration of the first hospitalization, whereas anxiety and DP/DR were inversely correlated (PHQ-9, RR 1.10, 95%CI, 1.09–1.11, p < 0.001; GAD-2, RR 0.79, 95%CI, 0.77–0.80, p < 0.001; CDS-2, RR 0.93, 95%CI, 0.90–0.95, p < 0.001). The gene discussed is GAD1; the disease is depressive symptom measurement.
