Abstract

Background: Health-related quality of life is a major issue among patients with multiple sclerosis (MS). Chronic rhinosinusitis (CRS) poses a significant occupational health concern, particularly among factory workers exposed to environmental irritants such as cement dust. Objective: To determine the prevalence of CRS among Vietnamese cement factory workers and to identify associated demographic, occupational, and environmental risk factors. Methods: A cross-sectional study was conducted from June 2023 to June 2024 at the Hai Phong Cement Factory, involving 1,054 workers directly exposed to cement dust. CRS diagnosis followed Rosenfeld’s clinical criteria, including symptom duration, endoscopic findings, and imaging results. Data on demographic, occupational, and environmental characteristics were collected through structured interviews and clinical assessments. Logistic regression analyses identified predictors of CRS. Results: The prevalence of CRS was 8.92% (n=94). Significant risk factors included co-existing ear, nose, and throat (ENT) diseases (OR: 4.67, 95% CI: 2.59–8.41, p
