Objective:To analyze the risk factors of stress perception in patients with systemic lupus erythematosus (SLE) , and construct and validate a risk prediction model for health risk stress perception in SLE patients.Methods:This study is a cross-sectional study. From October 2020 to March 2021, totals of 310 SLE inpatients and outpatients in the Department of Rheumatology and Immunology from 4 general hospitals in Anhui Province were selected as the modeling object. According to the patients' stress perception score, they were divided into the group with health risk stress ( n=132) and the group without health risk stress ( n=178) . The general data, SLE disease activity, general self-efficacy, emotional intelligence, resilience, sleep disturbance, anxiety, depression were compared between the two groups, and independent risk factors were screened out and Logistic regression was used to construct a risk prediction model. Hosmer-Lemeshow and receiver operator characteristic curve (ROC) area were used to test the fit and prediction effect of the model, respectively, and 206 patients were included for model validation. Results:Binary Logistic regression analysis showed that SLE disease activity, resilience, anxiety, payment type, and family monthly income were the influencing factors of stress perception in SLE patients, and the difference was statistically significant ( P<0.05) . Hosmer-Lemeshow fit test showed χ 2=6.123, P=0.633. Besides, the area under the ROC, maximum Youden index, predictive critical value, sensitivity and specificity were 0.903, 0.660, 0.497, 0.795 and 0.865 respectively. Conclusions:This study is based on five independent risk factors of SLE patients' stress perception, namely SLE disease activity, resilience, anxiety, payment type, and family monthly income. The risk prediction model has good sensitivity and specificity, which can provide a reference for clinical assessment of health risk stress perception in SLE patients.
