Developing a Job-Exposure Matrix for Sedentary Behavior: A Study Based on the Inpatient Clinico-Occupational Database of Rosai Hospital Group.

Abstract

Objective: The aim of the study is to develop a job-exposure matrix for sedentary behavior and assess its relationship with noncommunicable diseases.

Methods: We constructed a job-exposure matrix using occupational and industry classifications combined with data on daily average sitting durations from 41,718 individuals. This matrix was then applied to a cohort of 706,939 participants in a case-control study to explore the link between sedentary behavior and noncommunicable disease risks.

Results: The matrix effectively identified sedentary behavior across different occupational groups. Using the matrix to assess sedentary behavior, associations were found between increased sedentary activity and heightened risks of diabetes, acute myocardial infarction, and endometrial cancer, while a reduced risk was observed for stroke.

Conclusions: The job-exposure matrix provides valuable insights into the health impacts of sedentary behavior in the workplace, underscoring significant disease risks associated with prolonged inactivity.
