We conducted and evaluated a 4-year, web-based wellness program involving 2498 global employees. The program was designed to encourage improvement in diet, exercise level, and weight control. Each month, after enrollment, participants were prompted to log on and enter personal data. Four years' worth of nonparametric data were analyzed. Seventy-seven percent of participants were men, 53% were overweight or obese, and mean beginning body mass index (BMI) was 25.9. Only 35% of starting participants ate five or more servings of fruit and vegetables daily, and fewer than 38% engaged in 30 min of activity or 10,000 steps. At the end of the intervention, there was a statistically significant (p < 0.05) improvement in the diet, exercise habits, and weight of participants. Results suggests that our web-based wellness intervention was successful in improving key health indicators for a mobile, global workforce.
