Evaluation of the COVID-19 pandemic effect on the development of somatic symptoms in patients with mood disorders: a case-control study

Somatic symptoms are one of the most common complaints among patients with psychiatric disorders and are considered as one of the most common psychiatric disorders in the new coronavirus pandemic. This study aimed to evaluate the effect of the COVID-19 pandemic on the physical symptoms in patients with mood disorders and compare it with healthy individuals. In this case-control study, 67 patients with mood disorders were referred to the psychiatric clinic of 5 Azar Hospital in Gorgan, who met the inclusion criteria, and 68 healthy individuals as control group were entered into the study. For all participants after informed consent, a demographic information questionnaire was completed along with Screening for Somatic Symptoms-7 (SOMS7) and Patient Health Questionnaire-15 (PHQ-15), and the data were analysed by SPSS software version 25. The mean score obtained for the SOMS-7 questionnaire for the group of patients with mood disorders and the control group was 32.37 ± 8.19 and 35.42 ± 11.3, respectively. The mean obtained for the PHQ-15 questionnaire for the mood disorders group and the control group was 8.56 ± 5.93 and 5.86 ± 4.63, respectively. In the mood disorder group, 26.9% of patients had no risk for physical symptoms, 31.3% of patients had a low risk, 25.4% of patients had a moderate risk, and 16.4% of patients had a high risk for physical symptoms. The statistical test showed that although the risk of physical symptoms was high in both groups, this rate was higher in the group with mood disorders, and there is a significant difference between the two groups (P < 0.05). The results also showed a significant and direct relationship between the two questionnaires (P < 0.05). According to the results, although the prevalence of somatic symptoms increased in both groups, the prevalence of somatic symptoms is significantly higher in the mood disorder group.
