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 .
Environmental Changes to Control Obesity: A Randomized Controlled Trial in Manufacturing Companies
Purpose : To determine the effects of an environmental intervention on obesity , disease risk factors , and dietary intake in an employee population . Design : R and omized controlled community trial . Setting : Eight manufacturing companies in Kentucky with ~ 150 to 350 employees each . Subjects : R and omly selected employees . Intervention : Multicomponent environmental intervention that included employee advisory committees , point-of-decision prompts , walking paths , cafeteria/vending changes , and educational material s. Measures : Height ; weight ; body fat ; blood pressure ; fasting lipids , glucose and insulin ; and dietary intake were assessed prior to and 3 , 6 , and 12 months after initiation of the intervention . Analysis : Mixed-model repeat-measure analyses of covariance were used to analyze data collected over the study period . Categorical data were analyzed in contingency tables . A p value of .05 was used to judge statistical significance . Results : There were no intervention effects for outcome variables , with the exception of lower intake of saturated fat and dietary cholesterol in the intervention group compared to the control group . Over the course of the study , changes in anthropometry and bio measures were similar in both groups . Conclusions : Findings indicate that subtle environmental changes alone may not impact employees ' weight and health ; however , such institutional-level approaches may be essential to support healthy lifestyle habits that are initiated by more intensive efforts . Academic research ers should continue to partner with employers and practitioners to develop , implement , and evaluate innovative health promotion strategies including environmental interventions .
