Chronic Health Risks in Commercial Fishermen: A Cross-Sectional Analysis from a Small Rural Fishing Village in Alaska

Area of Science:

• Occupational Health
• Environmental Health
• Public Health

Background:

• Commercial fishing is a high-risk occupation with potential for chronic health issues.
• The National Institute for Occupational Safety and Health (NIOSH) prioritizes Total Worker Health™ initiatives.
• Understanding health risks in this population is crucial for developing effective interventions.

Purpose of the Study:

• To evaluate chronic health risks in commercial fishermen before and during the fishing season.
• To assess the impact of occupational factors on fishermen's health.
• To inform the development of health promotion programs.

Main Methods:

• A survey was conducted with gillnet license holders in Cordova, Alaska (n=607).
• Preseason (March 2015) and mid-season (July 2015) surveys assessed health behaviors.
• Physical exams and FitBit™ monitoring were performed on a subset of participants.

Main Results:

• Participants (n=66 preseason, n=38 mid-season) were predominantly white males, average age 49, with average BMI 27 (70% overweight/obese).
• During the fishing season, fishermen reported longer hours, less sleep, and reduced aerobic exercise (P < .05).
• Prevalence of hearing loss (80% at 4kHz), upper extremity disorders (70%), and rotator cuff tendonitis (40%) was high.

Conclusions:

• Fishermen exhibit higher rates of hearing loss, upper extremity disorders, and sleep apnea risk factors compared to the general population.
• Occupational exposures (noise, repetitive motions, long hours) exacerbate these chronic conditions.
• Targeted health promotion programs are essential for improving the total worker health of commercial fishermen.
