The Australian National Standard for rail workers five years on

Area of Science:

• Occupational Health
• Cardiovascular Health
• Public Health Policy

Background:

• RailCorp train drivers exceeded Australian population prevalence for obesity and hypertension.
• Cardiovascular risk factors significantly impacted fitness for duty in rail safety workers.

Purpose of the Study:

• To evaluate changes in health condition prevalence among train drivers five years post-implementation of the National Standard for Health Assessment of Rail Safety Workers.
• To assess the impact of the health standard on cardiovascular risk factors in rail safety personnel.

Main Methods:

• A retrospective file review of 1094 RailCorp drivers and driver recruits was conducted.
• Data was collected for health assessments performed between February 1, 2009, and January 31, 2010.

Main Results:

• Significant decreases observed in systolic blood pressure (35% to 22%), total cholesterol (39% to 32%), and smoking rates (25% to 20%).
• Significant increases noted in obesity (40% to 47%), diabetes (7% to 11%), and pre-diabetes (2% to 5%) prevalence.
• Despite adverse trends in obesity and diabetes, improvements in other cardiovascular markers resulted in a neutral overall cardiac risk score.

Conclusions:

• The rise in obesity among drivers mirrors general population trends and is also seen in new recruits.
• Increased screening likely contributes to the higher detection rates of diabetes and pre-diabetes, linked to rising obesity.
• Improvements in blood pressure, cholesterol, and smoking status offset negative trends, maintaining overall cardiac risk.
