Shift-Based Differences in Hemoglobin Levels of Female Factory Workers in Gresik

Abstract

Introduction: Work shifts, which can include morning, afternoon, or night shifts, are a system where employees are expected to carry out their responsibilities outside of regular business hours. This system may affect sleep patterns and circadian rhythms, which can result in fatigue and poor performance. Levels of haemoglobin. Materials and Methods: This study aims to determine the differences in haemoglobin levels between female employees working morning, evening, and night shifts at Gresik-area industries. This study uses a cross-sectional design and the observational analytical approach. Purposive sampling was used to select 35 female employees in total. After every work shift, haemoglobin levels were measured using the Point of Care Testing (POCT) method. The Two-Way ANOVA test was used to look at how the average haemoglobin levels varied between shift groups. Results: The results showed that the average haemoglobin concentration was 13.0 g/dL in the morning, 12.7 g/dL in the afternoon, and 12.3 g/dL in the night shift. The results of the Two-Way ANOVA test showed a significant change in haemoglobin levels across shifts, with a p-value of 0.000 (p<0.05). Conclusion: According to the study's findings, female employees haemoglobin levels significantly throughout the morning, evening, and night shifts, with the lowest levels seen during night shifts.
