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 .
Effectiveness of a Worksite Intervention for Male Construction Workers on Dietary and Physical Activity Behaviors, Body Mass Index, and Health Outcomes: Results of a Randomized Controlled Trial
Purpose : To evaluate the effectiveness of an individually tailored intervention for improvement in lifestyle behavior , health indicators , and prevention and reduction of overweight among construction workers . Design : R and omized controlled trial . Setting : Various blue-collar departments of a large construction company in the Netherl and s. Participants : Blue-collar workers r and omized to an intervention ( n = 162 ) or a control group ( n = 152 ) . Intervention : The intervention group received individual coaching sessions , tailored information , and material s to improve lifestyle behavior during a 6-month period , and the control group received usual care . Measures : Body weight , body mass index ( BMI ) , waist circumference , physical activity ( PA ) levels , dietary behavior , blood pressure , and blood cholesterol were assessed . Analysis : Effectiveness of the intervention on outcome measures at 6- and 12-month follow-up was assessed by using linear and logistic regression models adjusting for baseline levels . Results : After 6 months , a statistically significant intervention effect was found on body weight ( B = −1.06 , P = .010 ) , BMI ( B = −0.32 , P = .010 ) , and waist circumference ( B = −1.38 , P = .032 ) . At 6 months , the percentage of those meeting public health guidelines for PA increased significantly in the intervention group compared to the control group ( B = 2.06 , P = .032 ) , and for sugar-sweetened beverages , an intervention effect was found at 6 months as well ( B = −2.82 , P = .003 ) . At 12 months , for weight-related outcomes , these differences were slightly smaller and no longer statistically significant . The intervention was not effective on the total amount of moderate to vigorous PA and other dietary and health outcomes . Conclusion : Intervention participants showed positive changes in vigorous PA and intake of sugar-sweetened beverages compared to controls , as well as effects on weight-related outcomes at 6 months . Long-term effects were still promising but not statistically significant
Reduction in blood pressure , lipids and blood glucose was not statistically significant .
