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 .
Modest effects of a controlled worksite environmental intervention on cardiovascular risk in office workers.
OBJECTIVE To present the effects of a relatively modest environmental intervention on biological cardiovascular risk indicators . METHOD A controlled trial , including two worksites . Measurements ( i.e. , body composition , blood pressure and serum cholesterol ) took place at baseline and at 3- and 12-month follow-up . The 12-month environmental intervention ( The Hague , The Netherl and s , 2004 ) consisted of : a ' Food'-part : to stimulate healthier food choices by means of product information in the canteen , and a ' Steps'-part : focused on stimulating stair use by means of motivational prompts in staircases and on elevator doors . RESULTS Significant differences in change between groups ( n=540 ) in favor of the intervention group were found on : [ 1 ] total cholesterol for women ( -0.35 mmol/l ) ; [ 2 ] HDL for men at 3 months ( 0.05 mmol/l ) and 12 months ( 0.10 mmol/l ) ; and [ 3 ] the total-HDL ratio for the total intervention group at 3 and 12 months ( -0.45 mmol/l ) . Both groups showed a decrease in all body composition values at both follow-ups . A significant difference in change in systolic BP was found in favor of the control group ( approximately 4 mm Hg ) , due to an increase in the intervention group at both follow-ups . CONCLUSIONS Based on the contrasting results , this modest environmental intervention was ineffective in reducing cardiovascular risk in a population of office workers
