Background: Health-related work functioning may be relevant to the safety of mining haulage operations. This study examined the relationship of source-defined Stanford Presenteeism Scale categories and job tenure with reported occupational events among dump truck operators.
Methods: A cross-sectional study included 112 operators recruited by incidental sampling from a workforce of 155 at a mining services company in East Kalimantan, Indonesia. The source report used the six-item Stanford Presenteeism Scale (SPS-6) and a binary measure of occupational accidents during the previous 12 months. The score cut-off and event classification were incompletely documented. Available aggregate tables were used to verify Pearson chi-square tests and calculate crude prevalence ratios with approximate 95% confidence intervals.
Results: Forty-two operators (37.5%) reported an event. Events were reported by 41 of 49 operators (83.7%) in the source high SPS-6 category and 1 of 63 (1.6%) in the low category (crude prevalence ratio 52.71; approximate 95% CI 7.51–369.89; Pearson p < .001). Event proportions were 58.3%, 43.2% and 12.8% across the source new, intermediate and long tenure categories, respectively (Pearson p < .001). No adjusted estimates were available.
Conclusion: Source-defined SPS-6 categories and tenure were associated with reported events in this sample. The meaning and magnitude of the SPS-6 contrast require caution because scoring direction is unverified and the comparator contains one event. These findings do not establish that working while ill causes accidents or that a screening intervention prevents them
