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 .
Images of a Healthy Worksite: A Group-Randomized Trial for Worksite Weight Gain Prevention With Employee Participation in Intervention Design.
OBJECTIVES We assessed the effects of a  worksite multiple-component intervention addressing diet and physical activity on employees ' mean body mass index ( BMI ) and the percentage of employees who were overweight or obese . METHODS This group-r and omized trial ( n = 3799 ) was conducted at 10 worksites in the northeastern United States . Worksites were paired and allocated into intervention and control conditions . Within- and between-groups changes in mean BMI s and in the percentage of overweight or obese employees were examined in a volunteer sample . RESULTS Within-group mean BMI s decreased by 0.54 kilograms per meter squared ( P = .02 ) and 0.12 kilograms per meter squared ( P = .73 ) at the intervention and control worksites , respectively , result ing in a difference in differences ( DID ) decrease of 0.42 kilograms per meter squared ( P = .33 ) . The within-group percentage of overweight or obese employees decreased by 3.7 % ( P = .07 ) at the intervention worksites and increased by 4.9 % ( P = .1 ) at the control worksites , result ing in a DID decline of 8.6 % ( P = .02 ) . CONCLUSIONS Our findings support a worksite population strategy that might eventually reduce the prevalence of overweight and obesity by minimizing environmental exposures to calorically dense foods and increasing exposures to opportunities for energy expenditure within worksite setting
