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 .
Effectiveness of a Worksite-based Weight Loss Randomized Controlled Trial: The WORKSITE Study
Objective To determine the effectiveness of an individually-targeted Internet-based intervention with monetary incentives ( INCENT ) at reducing weight of overweight and obese employees when compared to a less-intensive intervention ( Livin ’ My Weigh [ LMW ] ) 6-months after program initiation . Design and Methods Twenty-eight worksites were r and omly assigned to either  INCENT  or LMW conditions . Both programs used evidence -based strategies to support weight loss . INCENT was delivered via daily e-mails over 12 months while LMW was delivered quarterly via both newsletters and onsite educational sessions . Generalized linear mixed models were conducted for weight change from baseline to 6-month post program and using an intention-to-treat ( ITT ) analysis to include all participants with baseline weight measurements . Results Across 28 worksites , 1,790 employees ( M=47 years of age ; 79 % Caucasian ; 74 % women ) participated . Participants lost an average of 2.27 lbs ( p<0.001 ) with a BMI decrease of 0.36 kg/m2 ( p<0.001 ) and 1.30 lbs ( p<0.01 ) and a BMI decrease of 0.20 kg/m2 ( p<0.01 ) in INCENT and LMW , respectively . The difference between INCENT and LMW group in weight loss and BMI reduction were not statistically significant . Conclusion The current study suggests that INCENT and a minimal intervention alternative may be effective approaches to help decrease the overall obesity burden within worksites
