Night shiftwork and prostate-specific antigen level in a tire manufacturing factory

Area of Science:

• Occupational Health
• Urology
• Endocrinology

Background:

• Emerging evidence suggests a potential association between night shiftwork and increased prostate cancer risk or elevated serum prostate-specific antigen (PSA).
• Prostate-specific antigen (PSA) is a key biomarker in prostate health monitoring and cancer screening.

Purpose of the Study:

• To investigate the relationship between rotating night shiftwork and serum PSA levels.
• To determine if night shift schedules impact prostate health markers.

Main Methods:

• A cross-sectional study involving 3,195 male production workers from a tire manufacturing facility.
• Measurement of serum PSA levels and collection of data on relevant confounding factors.

Main Results:

• The average serum PSA level was 0.98 ± 0.79 ng/mL.
• Lower PSA levels were observed in younger, obese, and physically active individuals.
• While night shift workers (n=2,832) had slightly lower PSA levels than day workers (n=363), this difference was not statistically significant.

Conclusions:

• This study did not find evidence supporting a link between night shiftwork and increased serum PSA levels, contrary to some prior research.
• Further investigation with consistent methodologies is required to clarify the complex association between shiftwork and prostate health outcomes.
