Abstract

Courier workers face high occupational demands that may impact their health, including gastrointestinal disorders. This study aimed to analyze the association between workload, work fatigue, and the incidence of gastric acid disease among package delivery couriers. An observational analytical study with a cross-sectional design was conducted in March 2025 at the main branch office of PT JNE in Medan. All 50 couriers were included as participants via total sampling. Primary data were collected through structured interviews using a pre-tested questionnaire. Data analysis involved univariate and bivariate analysis using the Chi-Square test. The incidence of gastric acid disease was 72%. Most couriers reported high physical workload (66%), high to very high mental workload (72%), and high to very high work fatigue (68%). Statistically significant associations were found between the incidence of gastric acid disease and physical workload ( p = 0.047 ) , mental workload ( p = 0.022 ) , and work fatigue ( p < 0.001 ) . The strongest association was with work fatigue, where 100% of couriers with high and very high fatigue levels experienced gastric acid disease. In conclusion, workload and work fatigue are significantly associated with the incidence of gastric acid disease among couriers.
