Reduction in blood pressure , lipids and blood glucose was not statistically significant .
Conclusions Workplace interventions  significantly reduced body weight , BMI and waist circumference .
Non-significant results for biochemical markers could be due to them being secondary outcomes in most studies .
Background Adults in urban areas spend almost 77 % of their waking time being inactive at workplaces , which leaves little time for physical activity .
The aim of this systematic review and meta- analysis was to synthesize evidence for the effect of workplace physical activity interventions on the cardio-metabolic health markers ( body weight , waist circumference , body mass index ( BMI ) , blood pressure , lipids and blood glucose ) among working adults .
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
