Abstract:Objective: To explore the relationship between somatization symptoms, anxiety, and depression in patients with chronic migraine (CM), and to provide reference for psychosocial evaluation and intervention in patients with chronic migraine. Methods: From January 2022 to February 2023, 278 patients with CM were collected from the Third Affiliated Hospital of Qiqihar Medical College. General clinical data were collected and the somatization symptoms, anxiety, depression, sleep, headache, and disability of the study subjects were evaluated using the Somatization Symptom Checklist (SSS), Generalized Anxiety Disorder Scale-7 (GAD-7), Patient Health Questionnaire - 9 (PHQ-9), Pittsburgh Sleep Quality Inventory (PSQI), NRS, and Migraine Disability Scale (MIDAS). Results: 150 patients with CM were screened positive for SSS, with a positive rate of 53.96%. Compared with SSS negative CM patients, SSS positive CM patients had a number of years of education [(9.95 ± 2.28) years vs (14.84 ± 4.01) years, t=2.228, P<0.012], a headache severity score [(3.89 ± 0.93) vs (6.95 ± 1.02) points, t=4.143, P=0.002], a headache duration [(6.69 ± 2.21) hours vs (19.73 ± 6.10) hours, t=4.892, P<0.001], a seizure frequency [(4.75 ± 1.63) times/d vs (8.38 ± 3.16) times/d, t=4.093, P=0.003] Headache duration [(8.17 ± 3.10) years vs (15.56 ± 4.73) years, t=4.441, P<0.001], disability score [(3.12 ± 0.83) points vs (5.91 ± 1.49) points, t=3.991, P=0.004], anxiety score [(2.87 ± 0.94) points vs (4.93 ± 1.91) points, t=0.731, P=0.315] Depression scores [(3.15 ± 1.79) points vs (7.17 ± 3.05) points, t=3.976, P<0.001] and sleep scores [(7.06 ± 3.14) points vs (12.50 ± 3.20) points, t=1.381, P=0.091] were higher. Analysis of related factors showed that headache severity score (P<0.001), headache duration (P=0.003), attack frequency (P=0.003), course of disease (P=0.001), disability score (P=0.004), anxiety score (P<0.001), depression score (P=0.003), and sleep score (P=0.004) were risk factors for somatization symptoms in CM patients. Conclusion: Somatization symptoms are common in CM patients, and severe headache severity, long duration of headache, frequent frequency of headache attacks, longer duration of headache, higher degree of disability, anxiety, depression, and poor sleep are risk factors for the occurrence of somatization symptoms in CM patients.
