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 .
Life-style intervention at the worksite--reduction of cardiovascular risk factors in a randomized study.
OBJECTIVES This study tested a feasible method for screening for cardiovascular risk at the worksite and investigated the effects of a long-term comprehensive program of life-style intervention to prevent cardiovascular disease . METHODS Employees in the public sector filled out a self-administered question naire with questions on social , medical , and work-related factors . The respondents numbered 454 ( 80 % ) . A score sum for cardiovascular risk was calculated ( range 1 - 20 , median 7.0 ) , and the 128 subjects with a sum above 8 were invited to a health examination including blood sampling . Thereafter the subjects were invited to participate , following r and omization , in a comprehensive , 18-month , life-style intervention program to improve cardiovascular risk or in a control group . RESULTS The intervention group significantly decreased body mass index , diastolic blood pressure , heart rate , low-density lipoprotein ( LDL ) cholesterol , and smoking habits during the intervention . The initially elevated serum cortisol , as a marker of stress reaction , normalized in the intervention group . In the control group LDL cholesterol also decreased , but the glucose and triglyceride levels increased , and smoking habits were unchanged . Sick days for a given period decreased after 1 year in the intervention group but not in the control group . CONCLUSIONS Several cardiovascular risk factors can be improved and morning serum cortisol normalized during a long-term life-style intervention program with a r and omized design using a worksite population of middle-aged subjects . The use of a 2-step screening program , with an initial question naire followed by a health check of subjects with elevated risk , is feasible for worksite setting
