Programs that had professionals frequently interact with participants , regardless if the interactions were done daily , weekly , or monthly , led to a change in body composition .
Additionally , programs that incorporated a motivation theory and provided content relevant to participants ' needs result ed in a change in body composition .
Conclusion Evidence supports that future worksite wellness programs that are design ed using a motivational theory and content that is created relevant to participants ' needs and that has frequent interactions with participants may result in a change in body composition

Worksite environment intervention to prevent obesity among metropolitan transit workers.
OBJECTIVE The results of an 18-month worksite intervention to prevent obesity among metropolitan transit workers are reported . METHODS Four garages in a major metropolitan area were r and omized to intervention or control groups . Data were collected during the fall of 2005 prior to the start of the intervention and during the fall of 2007 , after the intervention ended . Intervention program components at the garage included enhancement of the physical activity facilities , increased availability of and lower prices on healthy vending machine choices , and group behavioral programs . Mixed model estimates from cross-sectional and cohort sample s were pooled with weights inverse to the variance of their respective estimates of the intervention effects . RESULTS Measurement  participation rates were 78 % at baseline and 74 % at follow-up . The intervention effect on garage mean BMI change was not significant ( -0.14 kg/m(2 ) ) . Energy intake decreased significantly , and fruit and vegetable intake increased significantly in intervention garages compared to control garages . Physical activity change was not significant . CONCLUSION Worksite environmental interventions for nutrition and physical activity behavior change may have limited impact on BMI among transit workers who spend most of their workday outside the worksite
