Role of Blood Glucose Examination in Diabetic Shift Worker with Presenteeism: Is It Needed or Not?

Introduction. Abnormality in glucose metabolism could lead to diabetes. Shift workers experience physiological changes (zeitgeber) and circadian misalignment, thus increasing the risk of diabetes and will lead to various complication including on the occupation. It could affect cognitive function and could lead to presenteeism. Despite the condition, it is unclear whether routine blood glucose examination should be done in such case. Methods. Literature searching for the evidence-based has been conducted through “PICO” method. We continued the searching using electronic databases: “PubMed”, “EMBASE”, “Scopus”, “JSTOR”, and “Hand Searching”. Our inclusion criteria were human study, English article, full text article, and publication last for 10 years, while non-productive age population, animal study, duplicate article, and not-relevant article were excluded. Results. We found three valid cross-sectional studies. All of the studies were appraised by Oxford Centre of Evidence Based Medicine etiology worksheet. Discussion. Hyperglycemia could lead to worse performance on task of verbal and visual memory, visual perception, and attention and will lower productivity. Studies found that diabetic workers were prone to experience presenteeism loss higher than normal workers (high presenteeism loss; aOR 1.31 (1.04-1.66) vs moderate presenteeism loss; aOR 1.41 (1.17-1.70)) and poor glycemic control in diabetic workers had higher odds to experience presenteeism loss (aOR 1.80; 1.08-3.02). Conclussion. Shift workers could affect metabolic process leading to diabetes. While studies shown there were relation between blood glucose and presenteeism, however the evidence of routine blood glucose examination in shift worker apart from controlling glycemic level in diabetic workers hadn’t been established.
