Changes in coronary risk profiles in employees after three years of multifactorial intervention

Area of Science:

• Occupational Health
• Preventive Cardiology
• Behavioral Science

Background:

• Lifestyle-related cardiovascular risk factors pose a significant public health burden.
• Workplace interventions are increasingly recognized as a viable strategy for health promotion.

Purpose of the Study:

• To evaluate the effectiveness of a worksite intervention on cardiovascular risk factors.
• To compare outcomes based on the adequacy of intervention implementation.

Main Methods:

• 1555 employees in four Spanish worksites received individualized counseling.
• A blinded assessment evaluated intervention adequacy after 3 years.
• Coronary risk changes were analyzed overall and stratified by implementation adequacy.

Main Results:

• Overall analysis showed a non-significant reduction in mean coronary risk (-0.02%).
• Adequate intervention implementation led to a significant risk reduction (-0.12%).
• Inadequate implementation resulted in a non-significant increase in risk (+0.08%).

Conclusions:

• Appropriately implemented worksite health programs can achieve significant, albeit small, reductions in cardiovascular risk.
• The effectiveness of workplace interventions is highly dependent on proper execution.
• These findings support the role of worksite programs in preventive cardiology strategies.
