A 24-week worksite exercise program significantly improved sleep quality for employees. Women and shift workers experienced greater benefits from this intervention, highlighting exercise

Area of Science:

  • Occupational health
  • Behavioral science
  • Sleep medicine

Background:

  • Sleep disturbances are linked to increased disease risk in employees.
  • Exercise is a potential intervention for improving sleep quality, yet research is limited.
  • Worksite interventions offer a practical approach to address employee well-being.

Purpose of the Study:

  • To evaluate the impact of a 24-week worksite exercise and behavioral intervention on employee sleep quality.
  • To identify specific subgroups that may benefit most from such interventions.

Main Methods:

  • A 24-week worksite intervention combining exercise and behavioral components was implemented.
  • Self-rated sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).
  • Participants included 73 employees, with analysis comparing treatment vs. control groups and subgroups (women, men, shift workers).

Main Results:

  • The intervention group showed significantly greater improvements in PSQI scores compared to the control group.
  • Women and shift workers demonstrated more substantial improvements in sleep quality post-intervention.
  • Improvements in sleep scores were independent of baseline characteristics, psychological health, quality of life, or exercise compliance.

Conclusions:

  • A 24-week worksite exercise and behavioral intervention is effective in enhancing employee sleep quality.
  • Women and shift workers may particularly benefit from such programs.
  • Further research can explore mechanisms and long-term effects of worksite wellness initiatives on sleep.
