Shift work and dietary behaviors among Korean workers.

ABSTRACT:

Background

Shift work is associated with irregular dietary habits and poor nutritional intake, increasing the risk of chronic diseases. This study aimed to assess dietary quality and nutritional intake according to shift work status among Korean adult workers.

Methods

Data from 15 121 adult workers aged ≥20 years from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2013 and 2021 were analyzed. Dietary quality was evaluated using the Korean Healthy Eating Index (KHEI), and shift work status was determined by self-reported working hours. Associations between shift work and dietary quality were assessed using multivariable logistic regression, accounting for the complex survey design. Stratified analyses by gender were also conducted.
