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 .
Weight gain prevention in the school worksite setting: results of a multi-level cluster randomized trial.
OBJECTIVE To describe the effectiveness , reach and implementation of a weight  gain  prevention intervention among public school employees . METHOD A multi-level intervention was tested in a cluster r and omized trial among 782 employees in 12 central Massachusetts public high schools from 2009 to 2012 . The intervention targeted the nutrition and physical activity environment and policies , the social environment and individual knowledge , attitudes and skills . The intervention was compared to a material s only condition . The primary outcome measures were change in weight and body mass index ( BMI ) at 24-month follow-up . Implementation of physical environment , policy and social environment strategies at the school and interpersonal levels , and intervention participation at the individual level were assessed . RESULTS At 24-month follow-up , there was a net change ( difference of the difference ) of -3.03 pounds ( p=.04 ) and of -.48 BMI units ( p=.05 ) between intervention and comparison conditions . The majority of intervention strategies were successfully implemented by all intervention schools , although establishing formal policies was challenging . Employee participation in programs targeting the physical and social environment was maintained over time . CONCLUSION This study supports that a multi-level intervention integrated within the organizational culture can be successfully implemented and prevent weight gain in public high school employees
