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 .
Efficacy of a workplace-based weight loss program for overweight male shift workers: the Workplace POWER (Preventing Obesity Without Eating like a Rabbit) randomized controlled trial.
OBJECTIVE To evaluate the feasibility and efficacy of a workplace-based weight loss program ( Workplace POWER-WP ) for male shift workers . METHOD A prospect i ve , two-armed r and omized controlled trial of 110 overweight/obese ( BMI 25 - 40 ) ( mean [ SD ] age = 44.4 [ 8.6 ] years ; BMI = 30.5 [ 3.6 ] ) male employees at Tomago Aluminium aged 18 - 65 . In October ( 2009 ) men were r and omized to either ( i ) WP program ( n=65 ) or ( ii ) a 14-week wait-list control group ( n=45 ) . The 3-month program involved one information session , program booklets , group-based financial incentives and an online component . Men were assessed at baseline and at 14-week follow-up for weight ( primary outcome ) , waist circumference , BMI , blood pressure , resting heart rate , self-reported physical activity and dietary variables , and physical activity and dietary cognitions . RESULTS Intention-to-treat analysis using linear mixed models revealed significant between group differences for weight loss after 14 weeks ( P < .001 , Cohen 's d = 0.34 ) . Significant intervention effects were also found for waist circumference ( P < .001 , d = 0.63 ) , BMI ( P < .001 , d = 0.41 ) , systolic blood pressure ( P = .02 , d = 0.48 ) , resting heart rate ( P < .001 , d = 0.81 ) , physical activity ( P = .03 , d = 0.77 ) , sweetened beverages ( P < .02 , d = 0.5 - 0.6 ) and physical activity-related cognitions ( P < .02 , d=0.6 ) . CONCLUSION The WP program was feasible and efficacious and result ed in significant weight loss and improved health-related outcomes and behaviours in overweight male shift workers
