Area of Science:

  • Maritime Health
  • Occupational Medicine
  • Public Health

Background:

  • Danish seafarers exhibit a high prevalence of lifestyle-related diseases.
  • Obesity is a significant concern and potential safety issue within the maritime industry.

Purpose of the Study:

  • To investigate the prevalence of overweight conditions among male seafarers.
  • To assess the implications of establishing a maximum Body Mass Index (BMI) for seafarer employment.

Main Methods:

  • Utilized data from mandatory pre-employment health examinations, including height and weight measurements to calculate BMI.
  • Defined weight categories: normal (BMI 20-25), moderate overweight (BMI 25-30), and obesity (BMI ≥30).
  • Included basic information from seafarers' last employment period prior to examination.

Main Results:

  • The study included 1257 male seafarers.
  • Overweight prevalence was statistically higher in all age groups compared to a reference population ashore.
  • In the 45-66 age group, 76.6% were overweight, with 30.9% classified as obese.

Conclusions:

  • The employed methodology effectively profiles seafarer health objectively for national and international comparison.
  • High rates of overweight and obesity among seafarers pose risks to both individual health and shipboard safety.
  • Establishing fixed BMI limits for seafarers on Danish ships could result in widespread license loss, even with high thresholds.
