Multimorbidity patterns and its associated factors in Korean shift workers: A population-based study
ABSTRACT
Background:
Multimorbidity is a crucial factor that influences premature death rates, poor health, and healthcare utilization. Approximately one-fifth of the global workforce is involved in shift work which is associated with increased risk for several chronic diseases and multimorbidity.
Objective:
This study aimed to identify multimorbidity patterns and examine the factors associated with multimorbidity among shift workers in Korea.
Methods:
Data from the Korea National Health and Nutrition Examination Surveys (KNHANES) from 2016 to 2020 were utilized. The study included n = 1,704 (Weighted N = 2,697,228) Korean shift workers aged 19 and older. Multimorbidity patterns were identified by network analysis, and a survey-corrected logistic regression analysis was performed to identify influencing factors of multimorbidity among the workers.
Results:
The overall prevalence of multimorbidity was 13.7%. Network analysis results revealed that chronic diseases clustered into three groups: 1) cardiometabolic multimorbidity 2) musculoskeletal multimorbidity, and 3) an unclassified disease group. Logistic regression indicated that age, income, regular work, and obesity were significant factors influencing multimorbidity.
Conclusions:
The findings revealed that several socioeconomic and behavioral factors were associated with multimorbidity among shift workers indicating the need for policy development related to work schedule modification. Further organization-level screening and intervention programs are needed to prevent and manage multimorbidity among shift workers.
