Area of Science:

  • Occupational Health
  • Cardiovascular Disease Prevention
  • Health Promotion Programs

Background:

  • Elevated cholesterol poses a significant cardiovascular risk.
  • Worksite health programs are crucial for employee well-being.
  • Comprehensive programs may benefit from targeted interventions.

Purpose of the Study:

  • To assess the added value of a specific cholesterol management program.
  • To evaluate its effectiveness beyond existing health promotion efforts.
  • To determine its impact on employees with high cholesterol levels.

Main Methods:

  • A randomized controlled trial was conducted with blue- and white-collar employees.
  • Participants with cholesterol ≥ 240 mg/dL were assigned to an enhanced program (IMPACT) or a control group.

  • One-year follow-up serum cholesterol measures were obtained via venipuncture.

    • Main Results:

    • The enhanced program group showed a mean cholesterol decline of 16.6 mg/dL versus 10.0 mg/dL in controls.
    • While mean differences were not statistically significant, 36% of program participants reduced cholesterol below 240 mg/dL compared to 21% in controls.
    • This difference in percentage reduction was statistically significant.

    Conclusions:

    • The enhanced worksite cholesterol control program offers incremental benefits.
    • It is effective in increasing the proportion of employees achieving lower cholesterol levels.
    • Targeted interventions can enhance existing comprehensive health promotion programs.
