Summary

Shift workers are more likely to start smoking, independent of education. This highlights potential interventions for shift worker health risks.

Area of Science:

  • Occupational Health
  • Epidemiology
  • Public Health

Background:

  • Smoking is a confounding factor in cardiovascular disease risk among shift workers.
  • Previous studies suggested a link between shift work and increased smoking, but with small sample sizes.
  • The Maastricht Cohort study investigated the longitudinal relationship between smoking and shift work in a larger population.

Purpose of the Study:

  • To investigate the longitudinal relationship between shift work and smoking behavior.
  • To determine if shift work influences the initiation or cessation of smoking.
  • To provide data for health interventions targeting shift workers.

Main Methods:

  • Longitudinal study of 12,140 employees over two years using self-administered questionnaires.

  • Comparison between daytime workers (74%) and non-day shift workers (26%).
  • Logistic regression analysis adjusted for age, gender, and educational level to assess risks of starting or quitting smoking.

    • Main Results:

    • Shift workers had a significantly higher risk of starting to smoke during the follow-up period (odds ratio: 1.46, p = 0.03).
    • The risk of quitting smoking was slightly lower in shift workers but not statistically significant (odds ratio: 0.91, p = 0.5).
    • Shift work was independently associated with an increased likelihood of initiating smoking.

    Conclusions:

    • Shift workers are more prone to start smoking, irrespective of their educational level.
    • Findings have implications for understanding cardiovascular disease risk in shift workers.
    • The results support the need for targeted interventions to reduce smoking-related health risks in shift workers.
