Optimum weights for commercial divers.

R I McCallum, A Petrie

    British Journal of Industrial Medicine
    |May 1, 1984

    Summary
    This summary is machine-generated.

    Obesity increases decompression sickness risk in divers. Current weight tables are inaccurate for divers, leading to potential misclassifications and the need for updated standards.

    Area of Science:

    • Diving Medicine
    • Occupational Health

    Background:

    • Obesity is a known risk factor for decompression sickness.
    • Current height-weight tables used to assess diver fitness may be inappropriate for commercial divers.
    • Existing tables are based on general populations and may not accurately reflect divers' body composition.

    Purpose of the Study:

    • To evaluate the suitability of existing height-weight tables for commercial divers.
    • To determine if current obesity standards accurately identify divers at risk.
    • To highlight the need for updated reference standards for divers.

    Main Methods:

    • Analysis of weight measurements from 1520 divers in the Decompression Sickness Central Registry.
    • Comparison of diver weight data against a commonly used American height-weight table (1935-53).

    Related Experiment Videos

    Main Results:

    • Divers, as a group, are substantially heavier than the populations on which standard height-weight tables are based.
    • Using a 1935-53 American table, up to 13.6% of divers may be incorrectly classified as overweight.
    • Existing tables may lead to the exclusion of fit divers or the inclusion of at-risk individuals.

    Conclusions:

    • Published height-weight tables are unsuitable for assessing obesity in commercial divers.
    • There is a critical need for more recent and relevant height-weight data specific to divers.
    • Alternative or refined obesity measurements may be necessary for accurate diver fitness assessments.
