Existing predictive models lack integration of sociocultural and physiological factors, particularly in non-Western populations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To develop a culturally tailored risk-prediction model for depression in patients with somatization symptoms, emphasizing early identification and personalized intervention.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A prospective cohort study included 200 somatization patients (SSS\u226538, PHQ-2&amp;lt;3) from a Chinese hospital (May 2020\u2013August 2022). LASSO regression identified predictors from 18 variables, followed by multivariate logistic regression to construct a nomogram. Model performance was assessed via ROC-AUC, calibration curves, Hosmer-Lemeshow test, and decision curve analysis (DCA). Internal validation used 200 bootstrap resamples.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Five independent predictors were identified: advanced age (OR=1.11, 95% CI: 1.02\u20131.20), poor self-rated health (OR=2.07, 95% CI: 1.04\u20134.30), lack of co-residence with children (OR=1.63, 95% CI: 1.10\u20132.42), low income (OR=1.45, 95% CI: 1.05\u20132.01), and self-medication (OR=1.32, 95% CI: 1.01\u20131.73). The nomogram demonstrated strong discrimination (AUC=0.810, 95% CI: 0.728\u20130.893) and calibration (Hosmer-Lemeshow p=0.32). DCA confirmed clinical utility: at threshold probabilities &amp;gt;5%, the model provided higher net benefit than \u201ctreat-all\u201d or \u201ctreat-none\u201d strategies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This model integrates sociocultural (e.g., family structure) and behavioral factors to predict depression risk in somatizing patients, particularly in East Asian contexts. It offers a practical tool for clinicians to prioritize high-risk individuals, reducing diagnostic delays and healthcare burdens. Future multicenter studies should validate its generalizability and incorporate biomarkers (e.g., inflammatory markers) to enhance mechanistic insights.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpsyt.2025.1555513","type":"journal-article","created":{"date-parts":[[2025,4,1]],"date-time":"2025-04-01T08:49:49Z","timestamp":1743497389000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Construction
