To investigate the psychology status and quality of life in patients with inflammatory bowel disease(IBD) in China, and to analyze the influencing factors.

From September 2021 to May 2022, 42 hospitals in 22 provinces(autonomous regions and municipalities directly under the central government) in China, the clinical data of 2 478 IBD patients were collected, which included age, gender, weight, first visit or not, disease activity, disease course, main clinical manifestations(diarrhea, abdominal pain, hematochezia, extraintestinal manifestations), complications, treatment medication(5-aminosalicylic acid, glucocorticoids, immunosuppressive agents, and biological agents), and whether to have surgery. Anxiety, depression, sleep quality and quality of life of IBD patients were evaluated by generalized anxiety disorder-7 items, patient health questionnaire-9 items, Pittsburgh sleep quality index and inflammatory bowel disease questionnaire, and the related influencing factors were analyzed. Univariate analysis and multiple linear regression analysis were used for statistical analysis.

The average age of 2 478 IBD patients was 37.96 years old, and male counted for 62.43%(1 547/2 478). There were 61.82%(1 532/2 478) of the IBD patients in the active stage of disease, mostly mild or moderate(588 and 734 cases). There were 60.61%(1 502/2 478) of the IBD patients with different degrees of anxiety, 58.35%(1 446/2 478) of the IBD patients with different degrees of depression, and 48.87%(1 211/2 478) of the IBD patients had different degrees of sleep problems. The results of multiple linear regression analysis indicated that female, higher level of disease activity and longer disease course were independent risk factors of anxiety, depression and sleep quality in the IBD patients(unstandardized regression coefficient(95% confidence interval) 1.08(0.65 to 1.50), 0.45(0.23 to 0.68), 0.19(0.02 to 0.36), 0.83(0.33 to 1.32), 0.62(0.36 to 0.88), 0.28(0.08 to 0.47), 0.47(0.16 to 0.77), 0.39(0.23 to 0.55), 0.14(0.02 to 0.26); P<0.001, <0.001, =0.025 , =0.001, <0.001, =0.005, =0.003, <0.001, =0.027). The usage of biological agents was an independent protective factor of anxiety(unstandardized regression coefficient(95% confidence interval) -0.67(-1.17 to -0.17), P=0.008), and older age was an independent risk factor of sleep quality(unstandardized regression coefficient(95% confidence interval) 0.35(0.09 to 0.61), P=0.008). Higher level of disease activity, symptoms of diarrhea, abdominal pain, presence of extraintestinal manifestations, usage of 5-aminosalicylic acid and glucocorticoid, and with surgical treatment were independent risk factors of quality of life(unstandardized regression coefficient(95% confidence interval) -11.00(-12.24 to -9.76), -2.90(-5.26 to -0.55), -3.93(-6.25 to -1.61), -5.79(-9.87 to -1.71), -4.78(-7.79 to -1.76), -7.71(-11.07 to -4.35), -4.37(-8.00 to -0.73); P<0.001, =0.016, =0.001, =0.005 , =0.002, <0.001, =0.019), while the usage of biological agents was an independent protective factor of quality of life (unstandardized regression coefficient(95% confidence interval) 4.72(1.97 to 7.48), P=0.001).

IBD patients generally have different degrees of anxiety, depression and sleep problems, which affect the quality of life of patients. Gender, disease activity and disease course are the influencing factors of mental disorders in IBD patients.
