AbstractPrevious studies were controversial about the role of psychosocial factors in the pathogenesis of esophageal cancer (EC). This study aimed to systematically evaluate the effect size of psychosocial risk factors for EC in Chinese cohort.A literature search was conducted in both English and Chinese databases, and odds ratios (OR) with the corresponding 95% confidence intervals (CI) were pooled using a random-effects model.28 studies were identified with a total of 6951 EC cases and 7469 controls. The meta-analysis indicated a higher risk of EC among the individuals with psychological trauma (OR: 2.36, 95% CI: 1.71-3.26), Type A behavior (OR: 1.40, 95% CI: 1.17-1.67), depression (OR: 4.00, 95% CI: 2.44-6.55), melancholy (OR: 2.06, 95% CI: 1.32-3.20), always in sulks (OR: 2.49, 95% CI: 1.21-5.12), and irritable personality (OR: 2.13, 95% CI: 1.58-2.89). A lower EC risk was found in the individuals with good interpersonal relationship (OR: 0.35, 95% CI: 0.17-0.70) and outgoing personality (OR: 0.39, 95% CI: 0.19-0.78).This meta-analysis suggested a potential association between psychosocial factors and EC risk. For the individuals with psychosocial risk factors, physicians should pay more attention to EC screening.Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
