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
Background Adult obesity is globally recognized as a public health concern .
As adults spend most of their weekdays at work , worksite wellness programs may include topics of nutrition education and physical activity to improve an employee 's body composition .
However , results are inconsistent with the impact they have on employees ' body composition .
Objective The purpose of this systematic review was to evaluate  worksite wellness nutrition and physical activity programs and their subsequent impact on participants ' body composition .
Cost-effectiveness of a long-term Internet-delivered worksite health promotion programme on physical activity and nutrition: a cluster randomized controlled trial
This study aims to evaluate the cost-effectiveness of a long-term workplace health promotion programme on physical activity ( PA ) and nutrition . In total , 924 participants enrolled in a 2-year cluster r and omized controlled trial , with departments ( n = 74 ) within companies ( n = 6 ) as the unit of r and omization . The intervention was compared with a st and ard programme consisting of a physical health check with face-to-face advice and personal feedback on a website . The intervention consisted of several additional website functionalities : action-oriented feedback , self-monitoring , possibility to ask questions and monthly e-mail messages . Primary outcomes were meeting the guidelines for PA and fruit and vegetable intake . Secondary outcomes were self-perceived health , obesity , elevated blood pressure , elevated cholesterol level and maximum oxygen uptake . Direct and indirect costs were calculated from a societal perspective , and a process evaluation was performed . Of the 924 participants , 72 % participated in the first and 60 % in the second follow-up . No statistically significant differences were found on primary and secondary outcomes , nor on costs . Average direct costs per participant over the 2-year period were € 376 , and average indirect costs were € 9476 . In conclusion , no additional benefits were found in effects or cost savings . Therefore , the programme in its current form can not be recommended for implementation
