Risk Prediction of Coronary Artery Disease among Naval Forces

Background: Coronary artery disease (CAD) risk factors seem to cluster in some occupational groups. Objective: The present study was designed to investigate CAD risk factors among naval forces as an example of a high risk sector and to construct a risk prediction model for the disease. Methods: A case control study was carried out at the general naval hospital (GNH) in Alexandria. The study included 250 male consecutive naval CAD cases with a control group of 250 males matches for age, occupational level, sociodemographic characteristics and, free from CAD. All participants were subjected to a questionnaire about personal data, occupational history and exposures, occupational and leisure physical activity, dietary habits, smoking, and medical history. Anthropometric measurements, sitting blood pressure, and lipid profile were determined by the standard methods. Results: revealed that occupational sedentary activity and perceived occupational noise were the significantly reported special occupational characteristics together with other conventional risk factors among CAD naval cases verses controls (p
