Abstract
INTRODUCTION. Commuting accidents, defined as those occurring during the usual journey between home and the workplace or vice versa, may cluster or vary across working days. However, in Ecuador, evidence on these temporal patterns remains limited. OBJECTIVE. To assess the presence of the 'Monday effect' and the 'Weekday effect' in commuting accident injuries in Ecuador, and to explore heterogeneity by sex and age group. METHOD. Exploratory study based on administrative records from 2023–2024 (n = 3,469). Daily proportions (95% CI), relative index (Monday = 100), and linear trends (β, R²) of commuting accidents during peak commuting hours (Monday to Friday) were estimated. Differences between consecutive days were assessed using the Z statistic (p < 0.05). RESULTS. Men accounted for the majority of accidents (61%). Among women ≤29 years, a significant increase was observed on Tuesday compared with Monday (p < 0.05), while among men ≥50 years, a significant downward trend from Monday to Friday was detected (β = −7.67; R² = 0.871; p = 0.020). In other groups, variations were not statistically significant. DISCUSSION AND CONCLUSIONS. Commuting accidents in Ecuador show a homogeneous distribution across the working week, with no confirmation of the temporal patterns analyzed, though vulnerable subgroups were identified. Longitudinal studies are needed to further examine these findings and support targeted preventive measures focused on mobility during peak hours.
