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 .
Improving Employee Health: Evaluation of a Worksite Lifestyle Change Program to Decrease Risk Factors for Diabetes and Cardiovascular Disease
Objective : To determine whether an evidence -based , behavioral lifestyle intervention program delivered at a worksite setting is effective in improving type 2 diabetes and cardiovascular disease risk factors .  Methods : A r and omized 6-month delayed control design was utilized , with two thirds of the participants assigned to begin intervention immediately , and one third beginning 6 months later . The year-long program ( weekly for 3 months transitioning to monthly ) focused on weight loss and increasing physical activity . Results : The immediate intervention group had greater mean weight loss ( −10.4 lb , 5.1 % , vs −2.3 lb , 1 % ; P = 0.0001 ) than the delayed control group at 6 months and relatively greater improvements in activity , HbA1c , and other risk factors . The delayed group experienced similar improvements after completing the intervention program . Conclusions : A worksite behavioral lifestyle intervention is feasible and effective in significantly improving risk factors for type 2 diabetes and cardiovascular disease
