Economic results
No study included in the review measured the effect of worksite interventions on employee absenteeism, productivity and/or healthcare costs.
Environmental interventions
A relatively small number of studies evaluated the effectiveness of worksite environmental interventions alone[28,29] or in combination with health education
[21-25,33]. Findings of these eight studies were generally positive for dietary outcomes but effect sizes were small. Direct comparison with the eight studies that evaluated
employee education interventions is difficult due to variability in study design and outcome measures, but typically individual-level interventions appeared to deliver
slightly greater effects than environmental interventions.
