How Shift Work and Age Affect Workers in the Offshore Oil Industry

Circadian Biology Weekly Brief ↗PubMed ↗

Updated

Abstract

A total of 199 oil rig shift workers were examined for sleep and health issues related to shift work.

  • No significant associations were found between age or years of shift work exposure and sleep or health parameters.
  • Swing shift workers reported longer sleep duration compared to day shift workers.
  • Sleep duration for swing shift workers decreased with age, while it increased with age for day shift workers.
  • Significant associations were observed between morningness and sleep latency, sleep efficiency, and insomnia.
  • Findings suggest that older workers may tolerate shift work well, potentially influenced by a healthy worker effect or selection bias.
