Medical program for shift workers--impacts on chronic disease and mortality outcomes

Area of Science:

• Occupational Health
• Industrial Hygiene
• Public Health

Background:

• Shift work poses significant health challenges.
• BASF SE introduced a health program in 1983 for shift workers.
• The program included medical exams and health promotion.

Purpose of the Study:

• To evaluate the long-term health effects of BASF SE's supplemental health program.
• To assess the impact on mortality and disease incidence in shift workers.
• To understand the role of occupational health interventions.

Main Methods:

• Cohort study of 14,128 rotating shift workers and 17,218 day workers.
• Electronic job history searches and linkage to health/mortality records.
• 11-year follow-up period (1996-2006).

Main Results:

• Shift workers had marginally lower mortality risks.
• Higher incidence of obesity, diabetes, and circulatory/digestive diseases in shift workers.
• Observed differences may relate to surveillance or direct shift work effects.

Conclusions:

• Comprehensive occupational medical examinations and health interventions may reduce shift work's negative health impacts.
• Proactive health programs are crucial for shift worker well-being.
• Further research needed to differentiate surveillance effects from direct shift work impacts.
