title: Workplace physical activity interventions: a systematic review.
abstract: OBJECTIVE
  To assess the effectiveness of workplace interventions in improving physical activity.
  
  
  METHODS
  EBSCO research database (and all subdatabases).
  
  
  METHODS
  Articles were published from 2000 to 2010 in English, had appropriate designs, and measured employees' physical activity, energy consumption, and/or body mass index (BMI) as primary outcomes. Articles that did not meet the inclusion criteria were excluded.
  
  
  METHODS
  Data extracted included study design, study population, duration, intervention activities, outcomes, and results.
  
  
  RESULTS
  Data were synthesized into one table. Results of each relevant outcome including p values were combined.
  
  
  RESULTS
  Twelve (60%) of 20 selected interventions reported an improvement in physical activity level, steps, or BMI, and there was one slowed step reduction in the intervention group. Among these, 10 were less than 6 months in duration; 9 used pedometers; 6 applied Internet-based approaches; and 5 included activities targeting social and environmental levels. Seven of 8 interventions with pre-posttest and quasi-experimental controlled design showed improvement on at least one outcome. However, 7 of 12 randomized controlled trials (RCTs) did not prove effective in any outcome.
  
  
  CONCLUSIONS
  Interventions that had less rigorous research designs, used pedometers, applied Internet-based approaches, and included activities at social and environmental levels were more likely to report being effective than those without these characteristics.
