Seattle 5-a-Day Work-Site Project: process evaluation.
The Seattle 5-a-Day Work-Site Project developed a community-based intervention to increase fruit and vegetable intake, using both environmental (including cafeteria and work-site-wide events) and individual strategies. The Employee Advisory Board developed its own protocol from a common skeleton and a minimum set of activities. Small work sites and work sites with fewer female employees delivered more displays, posters, and table tents per employee (p < .01 and p < .05, respectively). Dose was neither related to use of the intervention nor to change in fruit and vegetable intake. Use of informational materials increased fruit and vegetable intake in the cohort of employees with both baseline and follow-up data (p = .05). The intervention was associated both with increased employee use of the intervention (activities and materials) and with increased intake of fruit and vegetables. Work sites with medium average baseline intake were the most responsive. These findings can guide the development of more efficient community-based dietary interventions.
