Area of Science:

  • Occupational Health
  • Cardiovascular Disease Prevention
  • Health Promotion Programs

Background:

  • Hypertension is a major public health concern, particularly in workplace settings.
  • Effective blood pressure control strategies are needed to reduce cardiovascular risk.
  • Work-site health promotion programs offer a platform for intervention.

Purpose of the Study:

  • To evaluate the incremental effectiveness of a comprehensive work-site blood pressure control program.
  • To assess the impact of counseling and personalized mailings beyond standard physician referral.

Main Methods:

  • A randomized controlled trial was conducted at four work sites.
  • Eligible participants (blood pressure >= 140/90 mm Hg) were randomized to an intervention or control group.

  • The intervention group received physician referral, monthly work-site counseling, and personalized mailings; the control group received only physician referral.
  • Main Results:

    • After one year, intervention subjects showed average blood pressure declines of 8.5/3.9 mm Hg compared to controls.
    • Adjusted analyses revealed decreases of 7.6 mm Hg for systolic and 2.4 mm Hg for diastolic blood pressure in the intervention group.
    • These findings indicate a statistically significant incremental benefit of the work-site program.

    Conclusions:

    • Work-site blood pressure control programs incorporating counseling and personalized mailings can provide incremental benefits.
    • Such interventions are effective in improving blood pressure control among high-risk employees.
    • Integrating targeted health promotion into the workplace is a viable strategy for cardiovascular disease prevention.
