    Area of Science:

    • Occupational Health
    • Biostatistics
    • Epidemiology

    Background:

    • Occupational mortality studies are crucial for worker health surveillance.
    • Accurate analysis requires robust statistical methods to account for confounding factors.
    • Existing methods may face challenges with data sparsity and comparison population selection.

    Purpose of the Study:

    • To develop an interactive computer program for analyzing occupational mortality data.
    • To provide flexibility in selecting comparison populations (internal, external, US general population).
    • To enable control for confounding factors and data collection differences.

    Main Methods:

    • The program computes standardized mortality odds ratio (SMOR) and standardized proportional mortality ratio (SPMR).
    • It allows user-defined age and time intervals to mitigate data loss from stratification.
    • Analysis involves selecting reference causes of death from predefined categories.

    Main Results:

    • The program offers rapid, cost-efficient interactive results on mainframe systems.
    • It enhances control over confounding variables through flexible comparison population selection.
    • User-defined interval lengths reduce information loss in sparse data scenarios.

    Conclusions:

    • The developed program provides a flexible and efficient tool for occupational mortality study analysis.
    • It aids researchers in controlling for confounders and improving data utilization.
    • The interactive nature and cost-efficiency make it valuable for occupational health research.
